Midea Cube 50 pint dehumidifier review

Midea Cube Dehumidifier Basement

Midea is a large Chinese electronic appliance company that has existed since 1968. It has over 160,000 employees worldwide and has an extensive product range from refrigerators to large HVAC systems. 

In a recent survey from Consumer Reports, Midea was included as one of the most reliable based on a survey of their members, so I was very excited when the Cube arrived.

Most residential dehumidifiers have a similar design: a rectangular box with a small bucket at the bottom. With the Cube, Midea has chosen a completely different technique that, as you can guess from the name, uses a cube as a bucket, allowing for a much bigger water bucket than the traditional design. 

The Midea Cube was launched in 2019, which means it is a reasonably new dehumidifier design. Since then, it has been very popular with consumers, so we were keen to test and review it for ourselves.  

I am reviewing the 50-pint model (MAD50PS1QWT) with a built-in pump, which is recommended for spaces up to 4500 square feet. This model is usually found for just under $300, but smaller versions go down to $200 for the 20-pint version.

  1. We set up the dehumidifier inside our very humid basement of 2,000 sq. ft.
  2. We set up our trusted SensorPush wireless hygrometer to track humidity levels in the air every minute while the dehumidifier is running.

A simple black cube that you can stack up

The large drainage bucket in the Midea Cube means you won’t need to make as many trips to the sink to get rid of the water removed from the air.

One thing I really like about this dehumidifier design is that you can save a ton of space when not using it by putting it inside the water bucket. This means that when storing, you will take up a lot less space than a traditional design.

Midea Cube Dehumidifier Open

You get the option of white or black. Personally, I like how well the black Cube looks; it easily fits into the surroundings in a place like a basement (which is where I have my Midea Cube).

You can see how different the design looks when comparing it to the similar-sized devices from Honeywell and Frigidaire. The entire box beneath can hold water, so you can really see how much extra water this device can hold compared to competing brands. 

The main fan is at the top of the device and a control panel is underneath. It includes a screen that gives you the level of humidity in the air as a percentage.

Midea Cube Dehumidifier Top

The control panel comes with buttons for adjusting the desired humidity and choosing the pump type. You also get a setting for selecting how high you want the bucket to fill up โ€” if you think the full 4.2 gallons will be too heavy to empty easily, you can reduce this so the device will only fill up half the bucket. Finally, you also get a timer button, meaning you can run the device for several hours.

Midea Cube Dehumidifier Control

Another great feature of the Midea Cube is the pump. When the Cube is in pump mode, the water the dehumidifier is pulling from the air can be simply pumped from the device into a drain through a pump drain hose that is included in the box.

I was pleased to see how clear the instructions were on the Cube itself:

My not-so-great experience setting up the Midea Air app

To set up the app mode, you will need to connect the Midea Cube to your phone by holding the power button for three seconds. From there, itโ€™s all about getting the Midea Air app set up on your smartphone.

Honestly, it was not easy setting up the Midea Air app on my iPhone. 

For starters, you canโ€™t use it on a 5ghz WiFi โ€“ even if your router can provide for both 2.4 and 5 GHz on the same network, you must create a WiFi connection that only has 2.4 GHz. They make this clear in the app, but this could be a total pain for people, especially those with a router from their internet provider that might not provide an easy way to set this up. 

The next issue I encountered was when I tried logging in using my Apple account. It did allow me to set up the app using this login, but when I tried to add the Midea Cube, it failed every time. 

I was able to set it up with a standard email address login, but feel that they should remove the ability to use third-party login choices if they donโ€™t work.

cq5dam.web .5000.5000

The setup involved several steps as the app connected to the onboard WiFi, and then finally, you chose the WiFi you want to use to control the dehumidifier. 

Compared with setting up the smart App with Levoit or Dyson, this was far from easy. I would love to see this improved in future iterations. 

There was also a concerning alert when I finally set up the app that said that the Midea Air app was no longer being updated and asked me to move to a different app than the one that was included in the material that came with the Midea Cube. You can still use the current Midea Air app, but it was concerning that they were not providing updates and I worry that, at some point, this app may no longer work. 

Once I was in the app and connected to my Midea Cube, I was happy with the overall design and UX. The Midea Air app includes features that are unavailable on the control panel, such as the estimated time when you will need to empty the water bucket.

00sefEqMi3KnLljaIjzi6Za 4..v1626202675

Setting the bucket level is also much easier with a simple visualization inside the app vs the numbers on the onboard control panel.

While the installation was far from easy, I could see myself using this app daily versus the on-board buttons because it saves me a trip down the basement.

Two filters to keep the device free of dust

The Midea Cube has two filters, one on each side of the device. This is a unique feature not found in many dehumidifiers.

A big issue for all types of dehumidifiers is ensuring that no dust or particles get into the device, as this can reduce the device’s efficiency and lead to faults over time. 

Most residential-style dehumidifiers use just one filter, so it was good to see the Midea Cube comes with two filters, one on each side. 

Midea Cube Dehumidifier Filter

Both filters use mesh to block small particles from entering the device and are easy to remove and clean. The dehumidifier also has a light to alert you when itโ€™s time to clean the filters.  

As a rule of thumb, it’s recommended to clean the filters every 2-3 weeks when the dehumidifier is used, as dust can accumulate quickly, especially in a location like a basement.

Tip

Be aware that these filters are used only to protect the machine. They wonโ€™t be able to clean the air โ€” you will need an air purifier if youโ€™re looking for air filtering capabilities.

The filters are easy to remove by just pulling them from the side. The best thing is that you can remove them fully to allow you to clean them thoroughly. Here is a video to show you how simple it is to do this:

The Midea Cube took 6 minutes to reduce the humidity in our testing tent

This powerful dehumidifier took only 6 minutes to reduce the air in our test tent from 65% to 45%

We tested the Midea Cube in a Gorilla Shorty Tent with a width and length of 3 feet and a height of 4.92 feet. This testing space has a volume of 44.28 feet, and this small space allows us to test all sizes of dehumidifiers in the same space. 

This model has also been tested by Energy Star and was found to remove 50 pints of water, which means it will be powerful enough to keep even a large area (up to 4500 sq. ft.) clear of humidity. 

Noise levels test results

Noise is a key feature for a device like a dehumidifier as you will likely have to run it continuously, so if it’s overly loud, this could create a problem. Thankfully, the Midea cube is a fairly quiet device, considering the amount of water it can remove in 24 hours. 

But noise can be subjective, so I made sure to include a video of the device running so you can hear for yourself:

The cost to run a Midea Cube: $446.78 per year

When buying a dehumidifier, upfront costs are important but you also need to be mindful of long-term costs.

Considering that a dehumidifier is an air conditioning unit in reverse, they can be power hungry and energy usage is higher with more powerful devices. 

While the total cost of running this device is on the high side, considering the amount of water it can remove, this is one of the most efficient devices on the market. With 1.8 liters of water removed for every kWh of energy, ENERGY STAR has certified this device

If you donโ€™t have a large space, you can reduce long-term costs by choosing a smaller device such as the 20 or 30-pint mode. Be sure to match the water removal level to the size and space of the location you want to reduce humidity.

Bottom line: Is the Midea Cube worth it?

An innovative design that is one of the best home dehumidifiers on the market

The Midea Cube is one of the best dehumidifiers we have reviewed for those looking to reduce humidity in their home.

Midea Cube Dehumidifier Storage

Itโ€™s priced well, considering the features and water removal rates, and it comes from a brand that has been making appliances for a long time. 

While we had some issues with the WiFi setup, its smart features worked well and made it easier to use the device in the long term. 

I would prefer to see a warranty that covers the dehumidifier for longer than just one year. Still, this is my favorite dehumidifier for consumers looking for a large water bucket that wonโ€™t need emptying all the time.

Levoit Core 300S review

Levoit Core 300S Kitchen Counter

If youโ€™ve decided you need an air purifier and researched the units available, youโ€™re most likely to have come across the Levoit brand. Levoit changed the game when they started engineering units in 2017 and have grown to be one of the most popular air purifier manufacturers on the planet.

The 300S is an upgrade on Levoitโ€™s hugely successful 300 to fit in with their Core S (Smart) range. That means that the Core 300S comes with a built-in sensor that monitors the air quality in your home in real-time, making it possible for the air purifier to come on automatically when needed. You can see air quality levels in your room on the screen, or you can access the data on your phone through Levoitโ€™s VeSync app.

But it begs the question, is it worth paying the extra $50 for the Core 300S over the 300?

To find out, we bought the Levoit Core 300S with our own money and put it through its paces to assess its air cleaning performance, sound levels at each fan speed, energy consumption, day-to-day usability and long-term maintenance costs.

With all this data, I will be able to compare the Levoit Core 300S to the more than 90 air purifiers we have tested to date. The result? A comprehensive review to help you decide if this is the right device for you.

The lowdown on the Levoit Core 300S

If you donโ€™t have time to read the full review, check out what I liked and what I think Levoit could have done better for the 300S.

What we really like

You can connect it to your smartphone through Levoitโ€™s VeSync app to operate it remotely, set routines and more.
It comes with an auto mode thanks to its onboard air quality sensor.
It shows the quality of the air in the room in real time via a bright LED wheel around the control panel.
There are lots of generic filters available, so you can rest assured you won’t find it difficult to find filters in stock when the time comes to replace them

What we think could be better

It doesn’t come with enough activated carbon to deal with serious odors or VOCs.
I wish you could remove the pre-filter to clean it, but it’s a bonded all-in-1 cylindrical filter.

Basic design, intuitive functionality

Levoit has engineered the Core 300S to be extremely user-friendly without compromising on design.

Levoit Core 300S Dining Room

Levoit isnโ€™t known for edgy designs, but that doesnโ€™t mean the 300S looks bad. Its white, cylindrical body is compact, light and easy to move between rooms. It doesnโ€™t take up much floor space and could also fit on a tabletop, desk or kitchen side.

The 300S sits firmly in the โ€œmid-sizeโ€ category when you put it next to some of the other Levoit units weโ€™ve tested. You can see in the image below how it compares to bigger Levoit devices such as the popular Vital 200S (left), the Core 600S (middle) and the EverestAir (right).

Levoit Air Purifiers Together

When comparing the 300S side-by-side with the 300, you will see that they look pretty much identical. The only visible differences can be found when looking at the control panel on top and when comparing the back of each devices.

Levoit Core 300S VS Core 300S Comparison 1

On the back of the Core 300S, you will find Levoitโ€™s AirSightโ„ข Plus air quality sensor. This feature scans the surroundings, detecting how many pollutants are in the air, in real time. You need to keep the air quality sensor unobstructed and free of dust for it to do its job effectively.

Levoit Core 300S Airsight

The 300S uses this air quality data to determine the most suitable fan speed when running in auto-mode, and it also stores it in the VeSync smartphone app.

But you won’t need to be looking at your phone all the time to find out how good the air quality is in your room because the 300S displays this information on the control panel on top of the device in the form of an LED color-coded ring around the power button:

Levoit Core 300S Controls

This brings me to the controls of the Core 300S and I’ve got to say, they are intuitive and easy-to-use at a glance, which is something I’ve come to expect from Levoit at this point.

There are minimal button descriptions, but the icons used are pretty self-explanatory. Here are which functions each button controls:

PowerPress once to turn the power on/off.
Press and hold to configure the air purifier and connect to the VeSync app.
Auto ModeWhen engaged, this allows the 300S to automatically adjust its fan speed to neutralize the amount of pollutants in the air (perfect for when my cat farts). 
Display LightsYou can turn off the display lights if you donโ€™t want them distracting you. Ideal for when Iโ€™m using auto mode at night.
Display LockPressing the button once locks the display so no settings can be altered. Press and hold for 3 seconds to unlock. Perfect if you have curious kids and/or pets.
TimerYou can set a timer to turn off your 300S for anything from 1-24 hours.
Night Mode/Filter ResetPressing the night mode button reduces the fan to its lowest speed and turns off the display lights for undisturbed sleep.
To reset the filter indicator light, press and hold for 3 seconds.
Fan SpeedCycle through three of the unit’s fan speeds.

There are a few more lights you will come across, all packed onto the control panel. On top are the fan speed indicators and the Wi-Fi signal to show that the unit is connected to your app. Below is the filter indicator light, which prompts you to replace the filter with a new one and an LED display to show the timer.

The smartphone app

As I mentioned briefly in the introduction, Levoit models in the โ€˜Sโ€™ (Smart) range include the ability to connect to their VeSync smartphone app. This allows you to have complete control of your 300S and the capacity to monitor the quality of the air in your home from anywhere in the world.

Connecting your device is a straightforward task and doesnโ€™t take long. All you need is to have the app downloaded, have a good wifi connection and be next to your air purifier. You can even connect multiple units to control and monitor the air quality in each room.

Levoit Core 300S App1

The app itself is very intuitive and easy to navigate. The air quality is displayed on the screen with buttons to control fan speeds, engage Auto or Sleep modes, and set a timer or schedule when you want the air purifier to power on and off.

Levoit Core 300S App2

If you have smart home devices at home already, you will be pleased to learn that you can connect the VeSync app to your Alexa or Google Home device in order to enable voice commands.

Levoit Core 300S App3

Hereโ€™s what happened when I subjected my 300S to a burst of airborne pollutants at close range.

3-stage air filtration with activated carbon

Years after its release, Levoit was forced to remove all mentions of HEPA filtration from their marketing.

Levoit prides itself on the quality of its filters, and so it should, as weโ€™ve never had any issues with them and found them to be extremely effective at removing harmful particles from the air. But a certain disruption has meant Levoit has had to make a few changes to their marketing materials.

Before I get into all that, letโ€™s talk about the filter itself.

Levoit Core 300S Filter

Inside the Core 300S, youโ€™ll find Levoitโ€™s trademark 3-stage filtration system:

  • Pre Filter – This is the first line of defense by trapping larger particles like dust and dander from the air by capturing them in its fabric material. By removing these contaminants here, it prolongs the life of the main filter. 

The pre-filter is the exterior layer of the Levoit Core 300S, so larger particles (such as pet hair and fluff) will get stuck to it. In order to extend the life of the other layers of the filter, you will need to vacuum the pre-filter regularly:

How to Vacuum Air Purifier Pre Filter

  • ARC Formulaโ„ข Activated Carbon Filter – This is made up of lots of small pieces of activated carbon that remove VOCs (Volatile Organic Compounds) and odors from the air using a process called adsorption. When these harmful pollutants hit the activated carbon they become stuck to it, unable to pass through.
  • Main Filter – This is where the magic happens. The main filter comprises of a tightly woven maze of fibers that trap microscopic particles (I always think of a fly trapped in a spider’s web), removing them from the air.

On August 15, 2023, Dyson contacted the National Advertising Division, stating that the branding of Levoitโ€™s filters was misleading by classifying them as HEPA.

In response to this challenge, VeSync (Levoitโ€™s parent company) โ€œasserted its belief in the efficiency of its productsโ€ and promised to update its testing data. Months later, Levoit instead opted for removing all traces of the word HEPA from its branding, packaging and promotional material.

So, does this mean that Levoit particle filters are inherently bad? Not really.

HEPA is an efficiency standard for air filters, but that doesn’t mean that only filters certified as HEPA are good. For example, we have seen excellent air cleaning results with air purifiers like the CleanAirKits Luggable XL-7, which uses MERV 13 filters instead of HEPA.

As I mentioned, you can check the remaining lifespan of your filter in the VeSync app but donโ€™t worry if you donโ€™t have access to that, as a red warning light will appear on your control panel when the filter needs to be replaced.

When the time comes, itโ€™s extremely simple to replace the filter:

  1. Unplug your Core 300S
  1. Turn the unit upside down and twist off the cap anti-clockwise
  1. Pull out the filter and replace it with the new one
  1. Twist the cap back on clockwise

Check out the process in my instructional video.

Tip

Levoit filters will arrive wrapped in plastic packaging, so itโ€™s paramount that you remove all of this before inserting the new filter into your 300S. If you donโ€™t, the filter simply wonโ€™t work, and youโ€™ll probably start to notice an unpleasant burning smell coming from your air purifier.

The Levoit Core 300S cleared our 728-cubic-feet test room in 45 minutes

This is two minutes slower than the Philips 800 Series but six minutes faster than the PuroAir 240.

Levoit Core 300S Kitchen Smells

We test all the air purifiers in the same rooms following the same process to assess the performance of each unit individually, as well as to make it possible to compare the data against other air purifiers we review. In this section of the article, I will take you through our tests.

Particle removal test

For our particle removal test, we lit an incense stick to fill our 728-cubic-feet test room with simulated contaminants. We then turned on the Core 300S at its highest fan speed and used our PurpleAir Zen particle counter to monitor how long it took for the 300S to clear all PM1 pollutants from the air.

Here are the results:

The 300S cleared our room of contaminants in 45 minutes, making it fifteen minutes faster than the original Core 300 (54 minutes).

The Core 300S is a small air purifier, so I wasnโ€™t expecting results to match units like the Levoit EverestAir (16 minutes) or the Blast Mini from Smart Air (15 minutes).

Considering its size, the 300S offers good air cleaning performance but there are other small air purifiers available today that proved to be more effective and that offer better value for your money like the Winix A231 (40 minutes) or the Philips 800 Series (43 minutes).

Noise levels test

All air purifiers make noise; whether it be the fan spinning or the motor running it, the sound is unavoidable. The issue is that if your air purifier is too loud, the likelihood is that someone will switch it off eventually as nobody wants to have a noisy fan running while doing deep work or watching a movie.

That is why we used a sound level monitor to record how much noise the Core 300S generates at each fan speed:

  • Speed 1: 38.9 dBA
  • Speed 2: 45.7 dBA
  • Speed 3: 54.5 dBA


When comparing the performance you get when running at top speed with the noise generated (54.5 dB), the Core 300S doesn’t particularly stand out as neither quiet nor noisy:

AIR PURIFIER MODELSOUND LEVEL AT TOP SPEED (dBA)TIME TO REACH PM1 ZERO AT TOP SPEED
Levoit Core 30050.2 dB(A)54 minutes
Philips 800 Series51.3 dB(A)43 minutes
Levoit Vital 100S53.8 dB(A)37 minutes
Levoit Core 300S54.5 dB(A)45 minutes
IKEA STARKVIND57.4 dB(A)32 minutes
Winix A231 (Zero Compact)57.9 dB(A)40 minutes
Molekule Air Mini+67.4 dB(A)61 minutes

When you compare it to other small air purifiers, youโ€™ll see that the 300S is on par. As you can see in the table above, the Winix A231 is louder than the 300S so if you were considering going with the A231 based on our particle removal test, then this is something to keep in mind.

Noise is subjective, so we video each unit we test to give you a good idea of how much sound it makes. Hereโ€™s the noise the 300S makes at each fan speed.

The cost to run a Core 300S: $79.43 per year

1. Electricity costs = $24.44 per year

Air purifiers need electricity to run, so the amount of energy it uses should be high on your list of considerations when looking to buy one. As the cost of energy continues to rise, finding an energy-efficient air purifier is more important than ever, especially as itโ€™s recommended you run your unit 24 hours a day.

The Core 300S is more energy-efficient than its predecessor, pulling 21.8 watts at its highest fan speed. Assuming you would run your 300S all day, every day at its top speed, this will add $24.44 to your annual electricity bill. Unless youโ€™re living in a consistently highly polluted area, you won’t need to have it at this level all the time, so the cost will most likely be lower.

When we compare the energy consumption of the Core 300S to other similarly sized (and priced) air purifiers, you will find that the 300S is a lot more energy-efficient than most:

AIR PURIFIER MODELENERGY CONSUMPTION AT TOP SPEED (watts)TIME TO REACH PM1 ZERO AT TOP SPEED
Philips 800 Series20.0 watts43 minutes
Levoit Core 300S21.8 watts45 minutes
Levoit Vital 100S27.3 watts37 minutes
Levoit Core 30035.5 watts54 minutes
PuroAir 24036.2 watts51 minutes
IKEA STARKVIND38.4 watts32 minutes
Molekule Air Mini+39.7 watts61 minutes
Winix A231 (Zero Compact)45.6 watts40 minutes

2. Filter costs = $54.99 per year

As filters trap particles from the air, they become full over time because those particles have nowhere to go. Most air purifiers use filters that need replacing when full, so itโ€™s important to factor the cost of replacing them into your budget.

Genuine Levoit filter replacements cost around $25.99 for the original and $35.99 for the higher-spec filters (which we highly recommend over the original filter). As each filter lasts from 6-8 months (depending on usage), you should budget for two a year ($54.99):

When combining energy consumption costs with filter replacement prices, we found that the Core 300S has some of the cheapest yearly running costs, second only to what we calculated when reviewing the Philips 800 Series:

Molekule Air Mini+$44.10$199.98$244.08

We tested the Pureburg generic filters that you can buy for $24 for two filters and found they slowed air cleaning performance a little but did use pelleted activated carbon like the genuine Levoit filters – a good alternative if you want to lower long-term costs a little:


Bottom Line: Is the Levoit Core 300S worth it?

The Core 300S is a worthwhile upgrade on the Core 300 and a good choise for a small bedroom, dorm or home office.

The Levoit Core 300S is small, smart and highly efficient at removing harmful pollutants from your home. Most importantly, it is affordable.

But is it dated?

Levoit Core 300S Kitchen

What was once one of the most affordable air purifiers on the market has been overtaken by one of the best air purifiers we tested in 2024: the AirFanta 3Pro. This model is part of a new generation of air purifiers powered by PC fans and designed to be built at home. So if the idea of a super silent but powerful small air purifier tickles your fancy, then check out our review of this awesome new device taking the air purification world by storm right now.

If you like the look of the Core 300S but have some more budget to play with or a large room to clean, then I recommend sizing up and going with the 400S instead. If you want to check out other newer models from Levoit, I suggest you take a look at the Vital 100S, which is priced in the same bracket as the 300S but outperformed it. 

Now, if you want something about the same size as the Core 300S with a cylindrical size and HEPA filtration, then you should check out the Winix A230/Zero Compact and the Philips 800 Series.

I still recommend the Core 300S to people with a small budget who want a reliable unit with smart functionalities and app support, but the market has changed, and there are other pretty great air purifiers available today that offer better value.

Levoit Vital 200S review

Levoit Vital 200S Living Room

Levoit is probably the best-selling air purifier brand in the United States. That fact will not surprise you if you, like me, have used Levoit air purifiers in your home.

Their product range includes top-end devices like the Levoit EverestAir, which is one of the fastest air purifiers we have tested, reaching PM1 zero in a swift 16 minutes. Levoit also produces budget-friendly air purifiers like the trusted Core 300, which managed to clean our room in 54 minutes.

So, we were excited to finally get a chance to test and review the Levoit Vital 200S. It has a more traditional look than the EverestAir or the Core series, and is aimed at medium-sized rooms up to 400 square feet.

We bought the Vital 200S with our own money so we could test it following the same methodology we have used to test over 100 air purifiers since 2020. In this review, I will share the results of our tests and my experience after having this device at home for well over two years now.

The pros and cons of the Levoit Vital 200S

A summary of our top-level findings after testing this air purifier following our methodology.

A super efficient fan combined with a high-quality particle and activated charcoal filter results in a powerful air purifier.

Retailing at $189.99, the Levoit Vital 200S gives you plenty of bang for your buck.”

CONS

It has a bonded filter, so once the carbon runs out (which usually happens within 6 months), youโ€™ll have to replace the whole thing, even if the particle filter still has life in it.
The air quality sensor is an optical sensor, so you need to keep it clean for it to report accurate readings.
I would like to see an independent test that could offer a filter grade after Levoit removed all mentions of HEPA from their marketing.

PROS

It offers a high level of air cleaning performance to $ ratio, completing our particle removal test as fast as units double its price.
You get smart features and smartphone connectivity through Levoit’s VeSync app.
It remembers settings and modes, so if you unplug it and plug it back in, the Vital 200S will still remember what it was last doing.
There are a ton of generic filters available that keep long-term costs low.

In August of 2023, Dyson officially challenged Levoitโ€™s use of ‘True HEPA 13 filters’ in their marketing and advertising through the BBB National Programs National Advertising Division (NAD). As a result, Levoit removed all mentions of โ€œHEPA H13โ€ in their marketing materials for all their air purifiers (including the Vital 200S).

Now, itโ€™s worth mentioning that a higher grade HEPA is not required to clean the air of even the tiniest particles, as lower grade filters still pick up these small particles in multiple passes. Still, we donโ€™t appreciate manufacturers not being transparent about technical specifications.

Design and smart features

Rather than use the cylindrical design we see with the Levoit Core series, the Vital 200S is a standard rectangle that pulls air from the front and pushes it out of the top. 

Levoit Vital 200S Close Up

Compared to the Levoit air purifier range, it shares a closer resemblance to the premium Levoit EverestAir, although I have to say I prefer the look of the pricier EverestAir โ€” do you blame me? Have a look at it:

Levoit EverestAir Fireplace
Levoit Vital 200S Sensor

You will need to clean the optical sensor every two months to ensure it continues to be accurate when using the device on auto mode. This is one of the reasons why I prefer laser sensors, as I know many people will forget to clean the sensor and this will lead to the air quality readings not being as accurate as they could be.

Levoit Vital 200S Top

From right to left you get an auto-mode button, a night mode button, the fan speed button, the power button, a timer button, a child lock button and lastly a button to turn the lights on and off. The power button is surrounded by an LED ring that changes color surrounded by lights that change color depending on indoor air quality. 

The Vital 200S comes with app connectivity through the VeSync app, which is the app used by a range of Levoit gadgets and is well-rated across Android and Apple ecosystems. 

Levoit Vesync App

The app uses Vesync, which is the app used by a range of Levoit gadgets and is well-rated across Android and Apple ecosystems. 

I tested the Apple app, and it was easy to install and add the Vital 200S quickly. You can adjust the air purifierโ€™s settings via the app and also see what the current indoor air quality rating is in the room where itโ€™s set.

Levoit Vital 200 App Ad
Levoit Vital 200 App

The main app screen has internal ads for different Levoit products, which I would prefer it didnโ€™t, but once you go into the air purifier, there are no ads shown. 

One feature that I havenโ€™t seen in other Levoit air purifiers is a light detection mode that allows the device to switch off the display and run extra quiet when low light is detected. This is a great feature for those wanting to use it in a bedroom.

Filtration technology

An all-in-one particle filter with pelleted activated carbon. You will need to replace both filters even if only one of them needs replacing.

Levoit Vital 200S Filter Side

Levoit initially stated that the Vital 200S uses HEPA H13, which is medical grade and can remove 99.97% of particles measuring 0.3 microns. But as you know, Dysonโ€™s challenges Levoit’s claims through the BBB National Programs National Advertising Division (NAD) and as a result, VeSync removed all mentions of ‘HEPA’ from their marketing materials.

Levoit Vital 200S HEPA Filter

It comes with a bonded particle and gas filter that performed very well in our particle removal test.

Levoit Vital 200S Activated Carbon Filter

The gas filter uses pelleted charcoal that is much better than the impregnated fabric we see with some manufacturers. 

How to Vacuum Air Purifier Pre Filter

It comes with a removable pre-filter which is much easier to clean than the pre-filter in the cylindrical Core 300/300S.

While you do get a good amount of activated carbon in the Vital 200S, if you have serious issues with VOCs and gasses, you should look for an air purifier with a much bigger filter with lbs of activated carbon such as the Alen BreatheSmart 75i, the IQAir HealthPro Plus and the Austin Air HealthMate.

Remember that most air purifier filters will arrive in a plastic bag, so be sure to remove the filter from the bag before you switch it on; otherwise, it will make your air quality worse!

Levoit Vital 200S Open

When the time comes to change the filter in your Levoit Vital 200S, youโ€™ll find that the process is simple and straightforward.

Air cleaning performance

The real-world performance of the Levoit Vital 200S matches reported CADR scores.

Running at full speed, the Vital 200S brought the levels of PM1ug/m3 to zero in 23 minutes. That makes the Levoit Vital 200S one of the fastest units we have tested under $200.

The Levoit Vital 200S was able to complete our particle removal test faster than the popular Winix 5510 but without using an ionizer function.

Levoit Vital 200S Particle Removal

As the table shows, the AirFanta 3Pro offered a higher clean air delivery rate for a cheaper price. This goes to show the power of PC fans compared to retail HEPA air purifiers.

Sound levels

In our testing, the sound levels of the Vital 200S ranged from 38.3 to 57.7 dBA

Levoit Vital 200S sound test

As I always say, air purifiers that are too loud, get turned off eventually. That is why we used a sound meter to measure how much sound the Levoit Vital 200S generates from three feet away. We did this across all four fan speeds:

FAN SPEEDSOUND LEVEL
Speed 138.3 dB
Speed 241.9 dB
Speed 353.8 dB
Speed 457.7 dB

We can now compare the air cleaning performance and sound level at top speed against data from other air purifiers in the same price range:

Levoit Vital 200S Sound Performance

As you can see from the table, the sound generated by the Vital 200S at top speed is quieter than that of most other air purifiers with a similar clean air delivery rate.

Running at the Vital 200S at speed 2 generates 42.5 dBA of sound, which is below the 45 dB(A) limit we have set for our quiet performance tests.

So I repeated the particle removal test with the 200S running at speed 2, and it managed to reach PM1 zero in 46 minutes.

Levoit Vital 200S Sub45 dB

As you can see from the table, the Vital 200S offers more powerful air cleaning performance at sub-45 dBA fan speeds than popular devices such as the Winix 5510 and the Coway Airmega 250S.

However, it is still no match to PC fan-powered air purifiers such as the Luggable XL-7 from CleanAirKits and the AirFanta 3Pro.

But sound can be very subjective, so we recorded a video of the air purifier running at different fan speeds:

Long-term running costs

Running a Levoit Vital 200S will cost you $99.47 per year, combining energy consumption costs and filter replacement prices.

As always, we used our energy meter, we recorded a maximum of 44.55 watts consumed by the Vital 200S when running at full speed. This equates to $49.48 per year if you were to keep it running 24 hours per day at its highest speed. 

Here are the full results for each fan speed:

MODEENERGY USAGE
Standby0.97 watts
Sleep mode3.21 watts
Speed 15.71 watts
Speed two8.01 watts
Speed 331.96 watts
Top Speed44.55 watts

This tells me that the Levoit Vital 200S has a very efficient fan that can move a lot of air without excessive energy usage. Itโ€™s great to see that newer models of air purifiers can perform well AND be energy efficient.

Considering you need to replace the filter every 12 months and that the replacement costs $49.99, you can expect to also spend $49.99 per year on filters.

When we combine the estimated electricity costs with the filter replacement costs, you can see that the Vital 200S offers great value in the long term as well:

Levoit Vital 200S Yearly costs

Regarding the filters themselves, you have other options in addition to the original filter: one aimed at those looking to deal with pet allergies, a smoke remover filter, and one that includes toxin absorbers. The price of these filters ranges from $49 to $65 dollars, so they are not cheap but they are also not super expensive.

If you want to reduce yearly running costs further, you will be happy to hear that there are many generic filters available for half the price of the genuine filters from Levoit – it’s worth mentioning that performance will vary:

Bottom line: Is the Levoit Vital 200S worth it?

With a list price of $189.99, it offers excellent value for the money, with air cleaning performance that matches units that cost twice the price.

Levoit Vital 200S Fireplace

If you want to get the best air cleaning for $ ratio and want to avoid ionizer technology, the Levoit Vital 200S is definitely worthy of consideration.

It includes many smart features that are normally only found on more expensive models but still manages to clean the air as effectively as we’ve seen from units like the iconic Winix 5500-2 but without the use of an ionizer.

Those with larger spaces will want to look at bigger units like the Levoit Core 600S ($299.99), but for those with a space between 400-500 square feet, the Vital 200S is a great choice as it will be able to keep your air clean for an affordable price. 

Noise levels associated to the Vital 200S are lower than the average and it comes with a sleep mode and the possibility of turning off the lights of the display (not to disturb your sleep), making it a very good option for a medium-sized bedroom.

Due to the lack of a True HEPA H13 filter, I don’t recommend this device for medical settings. However, as our in-house test showed, the Vital 200S can clean all tiny particles of 1 micron in 23 minutes. Air cleaning performance nearly three times as fast as the Levoit Core 300 ($99) and is only one minute slower than the larger Levoit Core 600S ($300).

For those who want to keep a medium-sized room clean of tiny particles and donโ€™t want to spend more than $190, then the Levoit Vital 200S is well worth checking out. And if money is tighter, do check out the PC fan-powered AirFanta 3Pro.

IQAir Atem Car review

IQAir Atem Car 2

Founded in 1963, IQAir is one of the oldest air purifier brands around. Their high-end (and high-priced) units are manufactured in Germany, which makes them stand out at a time when most other brands have moved manufacturing to China.

I immediately became a big fan of the IQAir Healthpro Plus when I reviewed it in 2021, although itโ€™s not cheap to buy or run, with filters costing up to $200 per year.

The IQAir Atem was released in 2017. It is aimed at people looking to use an air purifier in the car or as a portable unit for their desk. 

At $399.99, it costs the same as some larger air purifiers we have reviewed, so itโ€™s not cheap, but we had high expectations and wanted to see how well it performed at keeping the air inside our car clean. 

There are two versions of the IQAir Atem, the Atem Desk and Atem Car, both priced at $399.99. The only difference is that the filter used in the Atem Desk canโ€™t deal with gasses but the unit can be plugged into a traditional outlet โ€” the car model uses the car DC power outlet. 

For $99 you can buy a desk accessory kit or car accessory kit to swap modes. 

  1. In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
  2. We set up our trusted Purpleair Indoor Sensor with the latest Bosch gas sensor to track levels of PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 and VOCs in the air.

  3. We switch the air purifier to its highest speed and measure how long it takes to get our room air quality down to PM1 level to 0.

TL;DR The lowdown on the IQAir Atem Car

Danny Ashton HouseFresh
โ€œThe best car air purifier on the market. It cleaned our Tesla model 3 in 37 minutes, but it comes with a hefty price tag. It has a high-quality HEPA filter, which can remove gasses and odors. Still, for those on a budget, there are better value devices for keeping your air clean.โ€

IQAir Atem Car 2

PRICE on amazon PRICE on IQAIR

If you donโ€™t want to read my full review, here are my key findings to help you figure out if the IQAir Atem Car is the right air purifier for you: 

What we really like

It cleaned our Tesla Model 3 in 37 minutes โ€” 10 minutes quicker than the Smart Air QT3 and Westinghouse 1804.
Its design stands out for the right reasons.
The build quality is excellent, as expected from IQAir.
The HEPA filter is large and of high quality.
The app works well, but itโ€™s a little slow to adjust to changes.
Itโ€™s quiet when running on low fan speeds.

What we think could be better

The price โ€” at nearly $400, this is not an affordable air purifier.
Seat attachment didnโ€™t work on our Tesla Model 3 as it has no adjustable headrests โ€” it might be an issue if you drive a similar vehicle.
Touch buttons are not very intuitive and it was often easier to adjust using the app.

The specifications

Cost per CADR is a hefty $22.66 in comparison the Levoit Core 300 is 68 cents!

On paper, the IQAir Atem is a low-powered unit compared to traditional air purifier designs. Still, itโ€™s entirely designed for vehicle use โ€” with seat attachment and 12-24V DC power cable.

Clean design that fits a modern car 

As you can see, IQAir has gone for a modern design that will fit well in most vehicles, moving away from the clunky beige design we see with their larger units (and in other portable air purifiers).

IQAir Atem Front

Most of the car air purifiers we recommend have to be placed somewhere inside the car, but the IQAir Atem offers a few different options for where to put it.

The first and top option is to use the straps to put it in place around the headrest of the driver or passenger seat. In this way, it doesnโ€™t take up any space and can be easily adjusted by passengers in the back.

IQAir Atem Car 1

Sadly, this way of securing the Atem is not as effective in a Tesla Model 3 because the headrests donโ€™t have the normal rails. This didnโ€™t deter me from strapping the Atem to my seat but, while it did fit, it wasnโ€™t fully secure.

IQAir Atem Back

IQAir also recommends strapping it in an empty seat in the back. This isnโ€™t perfect, as it uses up a full seat, but itโ€™s a good option for those with headrests that donโ€™t work with the IQAir Atem design.

When we compare the IQAir Atem to other portable units, you can see itโ€™s much bigger and far less portable than other car air purifiers:

Portable Air Purifiers Comparison

Similarly to some of the portable air purifiers, there is no screen on the Atem. Now, what I wasnโ€™t expecting is the lack of physical buttons: everything is done with one touch by pressing the Atem logo that sits in the center of the device.

IQAir Atem Car 3

You will hear a sound when pressing the logo, but I found it was hard to hear it when there was a lot going on or the kids were in the car with me. That is why I ended up using the app to adjust the fan speed a lot more often than the button.

IQAir Atem Car App

Powerful HyperHEPA Plus filter

The car version of the IQAir Atem comes with IQAirโ€™s famous HyperHEPA Plus filter that can clean the air from pollutants as well as gasses and odors. This is essential when driving on highways or roads with high levels of traffic pollution.

IQAir Atem Open

When you take the filter out of the IQAir Atem Car you can see where that $400 was spent. 

The sizeable filter takes up a lot of space in the unit.

IQAir Atem HEPA top

The HyperHEPA filter is clearly of high quality, similar to what is used in IQAirโ€™s larger models. I was surprised at first to see a small, cheap-looking carbon-like filter on one side, but I realized that this was just a filter to protect the fan and isnโ€™t used to clean the air.

IQAir Atem Fan filter

The Atem Carโ€™s HyperHEPA Plus is $10 more and includes gas filtration technology. The regular Atem Desk filter only includes HEPA without the ability to clean the air from odors and gasses.

IQAir Atem HEPA Side

The filters are easily removed once you click the button on the back of the device near the power cord.

IQAir Atem No Filter

Many air purifiers will ship their HEPA filters in plastic, so ensure you remove them before starting the unit, or it wonโ€™t work.

The Atem cleared our Tesla Model 3 in 37 minutes

Similarly to other portable air purifiers, I tested the IQAir Atem in two different environments: the interior of our Tesla Model 3 (around 97 cubic ft.) and inside our 728 cubic ft. test room.

In both cases, I first used an incense stick to fill the space with smoke pollutants. Then, I recorded how fast the IQAir Atem could clean the air while running at its top fan speed. As usual, I did this by measuring PM1.0ug/m levels in real time with the help of our industrial quality air quality sensor from PurpleAir, which uses the latest Bosch BME680/688 gas sensor.

Itโ€™s worth mentioning that before running this test inside my car, I ensured all internal fans in the Tesla Model 3 were switched off. The results of this test are based on running the IQAir at its highest possible fan speed while being plugged into the car: 

Air cleaning performance test results

I expected the IQAir Atem would be faster than other portable units that we have tested like the Smart Air QT3. Still, I was impressed with how fast it could clean our Tesla Model 3 of particle pollution. See the comparison below:

When comparing the performance of the IQAir Atem to small corded air purifiers AND portable air purifiers cleaning the air inside our home lab, I was actually quite pleased to see how well the Atem faired:

Noise levels test results 

The standard noise levels are very quiet on speeds 1 (35dB) and 2 (40dB) and you often forget that the air purifier is running. I changed the fan speed in the app to 100% and the noise is pretty noticeable at this speed (58dB), so I can understand why this is not the default.

Overall, the Atem runs a little louder than the Smart Air QT3 at both its lowest speed (35dB vs 32dB) and highest speed (58dB vs 49dB).

The cost to run an IQAir Atem: $106.46 per year

For a small air purifier, itโ€™s not a cheap unit to run โ€” it costs much more than other portable purifiers, due to the high price of its HyperHEPA plus filters.

1. Electricity costs = $16.47 per year

Like other small, portable air purifiers you can use inside your car or other vehicles, the IQAir Atem doesnโ€™t use much energy. Our meter reading test showed that it pulls just 10.8 watts when running at its highest fan speed. 

Assuming we run the IQAir Atem for 24 hours a day every day (365 days) non-stop, it would still only use $16.47 worth of energy.

IQAir Atem Power

2. Filter costs = $89.99 per year

Similar to the larger IQAir units, the filter costs associated to the IQAir Atem are much higher compared to other portable air purifiers. The HyperHEPA Plus Filter costs up to $89.99 per year and the HyperHEPA Plus costs $79.99, but it cannot deal with gasses and odors. 

At the point of writing this review, no generic filters are available for the IQAir Atem Car, so you will have to stick to genuine IQAir filters. The only problem is that IQAir filters seem to be unavailable on Amazon, so you will need to get them directly from IQAir.com. Not as convenient as I would like.


Bottom line

The IQAir Atem is the best car air purifier on the market right now. 

Yes, it isnโ€™t as affordable as other portable air purifiers. Yes, the filters are not available to buy on Amazon and are quite expensive too. But one cannot deny the sheer air cleaning power of this device.

IQAir Atem Room

Those looking to save money would be better off with something like the Smart Air QT3 or the Westinghouse 1804.

But the IQAir Atem is my top pick for a car air purifier for those of you who drive through highly polluted highways and roads every day, and who have a good budget to spend. You wonโ€™t regret buying an air purifier from IQAir.

Westinghouse 1804 review

Westinghouse 1804 Car Panel

Westinghouse was founded in 1886 by inventor George Westinghouse. Over the years, it has been involved in many markets, from nuclear power to buying the TV broadcaster CBS.

Today, many consumer products are created by Westinghouse – from commercial pressure washers to air purifiers. The Westinghouse 1804 is designed to be a portable air purifier with an onboard lithium-ion battery. 

Itโ€™s relatively unique in the market as it combines a True HEPA filter with NCCO technology, a type of catalytic oxidation that, in lab tests, has been shown to reduce levels of VOCs.

The main competitors to the Westinghouse 1804 would be other portable air purifiers like the Smart Air QT3, Pure Zone Mini and the IQAir Atem

  1. In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
  2. We set up our trusted Purpleair Indoor Sensor with the latest Bosch gas sensor to track levels of PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 and VOCs in the air.
    purpleair
  3. We switch the air purifier to its highest speed and measure how long it takes to get our room air quality down to PM1 level to 0.
  4. For portable air purifiers, we repeat this test inside our Tesla Model 3 to see how good the unit is at cleaning the air in a small enclosed space.
    Testing QT3 in Tesla
  5. We use an energy meter to measure precisely how much electricity is used when running the unit at the lowest and highest fan speed settings.
    enery meter
  6. We track sound levels emitted by the air purifier at different fan speeds with the help of a commercial sound meter.

We take our air purifier tests seriously and never recommend any models until we thoroughly evaluate them in our home lab. 

Using our in-house test data means we can avoid the marketing jargon used by many air purifier brands and have a simple way to show consumers how well a device will perform in their home.

TL;DR The lowdown on the 1804

Danny Ashton HouseFresh
โ€œAn impressive 47 minutes at removing all pollutants from our Tesla Model 3, I was impressed with how well the unit could run on battery power alone. I am still not sure how comfortable I am with the NCCO reactor as itโ€™s still a new technology, but for its size, this unit is very efficient at removing particle pollution from the air.โ€

What we really like

Small design with a solid leather-like handle makes it easy to move around
Fast at removing pollutants from our test environment of the Tesla Model 3 in 47 minutes
Quiet operation, especially when compared to pure HEPA-based portable air purifiers
Powerful battery of 3000 mAH that lasts up to eight hours
HEPA filters are cheap at $8
The NCCO filter only needs replacing every 5 years

What we think could be better

NCCO technology could potentially create chemical byproducts, similar to ionizer air purifiers
No smart mode like app support or auto-mode
Only two fan speeds to choose from

The specifications

Cost per CADR of $8.60 is higher than the Smart Air QT3 ($2) but less than the IQAir Atem ($10.23)

As we expect with a portable air purifier, this has a much lower CADR than we see with traditional designs used in the home. We expected it to perform less than the Atem or QT3 due to its lower CADR score.

Easy to carry and simple design

The Westinghouse 1804 is a simple air purifier that is easy to carry around or keep in the car.

Westinghouse 1804 Front

Weighing just one kilogram, the Westinghouse 1804 is light, small and easy to carryโ€”the perfect combination for a portable air purifier.

The combination of white and cream colors with accent details in brown leather might not be everyoneโ€™s cup of tea, but it wonโ€™t stand out like a sore thumb in most vehicles.

If youโ€™ve been browsing through portable air purifiers for a bit, you might recognize that the Smart Air QT3 shares the same color palette: 

Portable Air Purifiers Comparison

When comparing the Westinghouse 1804 with other car air purifiers we have tested, you will see that this unit blends into the group. Itโ€™s not as small as the PureZone Mini but it is definitely smaller than the QT3 and looks tiny compared to the IQAir Atem Car.

True HEPA and NCCO technology filtration

One of the standout features of the Westinghouse 1804 is that it uses a combination of True HEPA filtration with an NCCO reactor.

Westinghouse 1804 Unit filter

When you first receive the Westinghouse 1804, you will see that the True HEPA is wrapped in plastic, and the NCCO reactor is a foil wrapper.

Westinghouse 1804 Filter Packaging

Tip

Make sure to remove all the filter packaging; otherwise, the unit wonโ€™t work. 

The True HEPA filter is pretty large, considering how small the Westinghouse 1804 is:

Westinghouse 1804 HEPA

Upon closer inspection, I could see the True HEPA filter in the Westinghouse 1804 is of high quality, as one would expect from a big brand such as Westinghouse.

When it comes to replacing the filter, the process is pretty straightforward:

The one button on the right side makes removing the front case section easy. Once you open it, you can see the True HEPA first and then the NCCO zeolite filter behind it. 

Westinghouse 1804 Unit no filter

The Westinghouse 1804 is super easy to control as it only has one button that switches the unit on and then, with extra presses, changes the fan speed. It only has 2 fan speeds.

Westinghouse 1804 Controls

What is an NCCO reactor anyway?

Iโ€™ll be honest: when I first read the word โ€˜reactorโ€™ after NCCO, I got slightly worried as it doesnโ€™t sound safe at all.

Upon reading about it, I learned that NCCO stands for Nano Confined Catalytic Oxidation. NCCO technology uses โ€˜contained ozoneโ€™ in combination with zeolites (microporous, crystalline materials used as commercial adsorbents and catalysts) and other porous materials to decompose pollutants into water vapor and carbon dioxide. 

When you open the NCCO reactor, we can see the Zeolite balls used in the NCCO process. 

Westinghouse 1804 Filter

I didnโ€™t like the mention of ozone, so I did some more research and found a study that states that there is no secondary pollution or re-release of pollutants in the NCCO process. This means that even though ozone is involved, and unlike ionizing technology, the Westinghouse 1804 shouldnโ€™t be releasing ozone into the air.

This all sounds good, but I wanted to investigate further. 

I noticed that the Westinghouse 1804 used special triangle screws to secure the front panel of the unit. Thanks to the magic of Amazon.com, I could obtain a set of specialized screwdrivers that allowed me to open up the Westinghouse 1804 so I could have a closer look under its hood to see what was hiding behind the front panel.

Opening Up the Westinghouse 1804

As soon as I removed the front panel, I could see the main fan, which is connected to the motherboard, 3200 mAH battery and a strange black box that seems to be part of the NCCO system. 

Thanks to the magic of Google Lens, I identified this as a negative ion module, making me think that the Westinghouseโ€™s NCCO reactor is just a zeolite filter combined with an old-fashioned ionizer function. Ionizers used to be super popular ten years ago but were pulled from the market as many units were found to release dangerous ozone levels. 

This might explain why security bolts were used on the device, as this ionizer could generate high ozone levels if not enabled with the zeolite filter. 

I used my ozone detector while running the Westinghouse 1804 inside my car and it didnโ€™t take long for ozone levels to rise up to 0.3 ppb. This is a very low amount of ozone but it is not zero.

Ozone detector VS Westinghouse 1804

Of course, it is way lower than the 50 ppb threshold set in order to achieve a CARB certification, which the Westinghouse 1804 has.

I am disappointed to see the use of an ionizer and more so from their lack of openness about this with references to NCCO. 

The 1804 cleared our TeslaModel 3 in 47 minutes

As we have been doing portable air purifier tests, we have been using our Tesla Model 3, creating incense smoke and then measuring how long each air purifier takes to remove all PM1ug/m3 pollutants. 

Westinghouse 1804 Testing

The Tesla Model 3 has a reasonably small cabin with around 97 cubic feet of volume. Similar to our home lab tests, we used the industrial grade sensor in the Purpleair Indoor sensor to continuously track levels of  PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m.

You can see our data below:

Air cleaning performance test results

With a CADR of 15 CFM, I was expecting it to perform to be a little better than the Pure Zone Mini, which has a CADR of 10 CFM, but I was surprised to see it perform as well as the QT3 and only 10 minutes slower than the $400 IQAir Atem. 

Combining the ionizer โ€œNCCOโ€ and true HEPA allows it to remove pollutants much quicker than we would assume, going off the reported CADR scores alone. 

While I was disappointed that the Westinghouse 1804 uses an ionizer, I canโ€™t disagree that it performed well at removing pollutants in the car.

Noise levels test results

One area of the Westinghouse 1804 that stands out is the low level of sound used, with a maximum of 39.8 dB. This is similar to what we see with other brands that use ionizers like Blueair, as they can run the fan lower but clean the air more efficiently due to the use of an ionizer.

The Westinghouse performed well when compared with other portable units.

Sound can be very subjective, so we created a video of the Westinghouse 1804 running at both its fan speeds.

The cost to run a 1804: $27.81 per year

1. Electricity costs = $3.81

As we expect with a portable air purifier, the Westinghouse 1804 doesnโ€™t use much energy, with 2.5 watts pulled at its highest speed.

2. Filter costs = $24

While the True HEPA filter replacements only cost $8 each, you need to change them every 4 months. You can even get the price down to $5 if you use generic filters.

This is much less than the IQAir Atem Car and just a little less than what we see with the Smart Air QT3.

When comparing the costs associated with running the Westinghouse 1804 with other portable air purifiers, it is clear that the 1804 is the most cost-efficient unit:

Bottom line

The Westinghouse 1804 is a powerful and cheap portable air purifier, but I do worry about the use of an ionizer.

Westinghouse 1804 Car Panel

At $129, the Westinghouse 1804 is cheap, especially compared to the $400 IQAir Atem Car. It performed well in our test to remove pollutants from our Tesla Model 3, but I am concerned about the use of an ionizer. 

If you donโ€™t worry too much about the ionizer and are happy to get better performance for a reasonable price, then the Westinghouse 1804 is worth a look. 

But for most people, we would recommend the Smart Air QT3 as itโ€™s cheaper to buy and has the same level of performance with zero risks of chemical by-products.

At HouseFresh, we have been reviewing air quality products since 2010. In all these years, we learned not to rely on manufacturers’ claims and the ever-so-glowing marketing materials. That is why we buy products with our own money, so we can write unbiased reviews after we’ve had enough time to evaluate air quality products in our home lab. Every unit we recommend has been thoroughly tested to assess its performance, energy consumption, and noise levels emitted in real-life environments. If you have any questions about our testing process for different types of air quality products, just drop us an email at danny@housefresh.com.

SOURCES

We calculated yearly costs associated with running the Westinghouse 1804  24 hours a day, 365 days per year utilizing the latest average energy prices as reported by the Bureau of Labor Statistics of $0.174/kWh as of May 2024.

Alen BreatheSmart Flex review

Alen BreatheSmart

Alen is a well-known brand in the world of air purifiers and the Austin-based company has been building air purifiers since 1999. They currently have 72 employees and had a revenue of just under 30 million dollars last year. 

One of their stand-out features is a lifetime guarantee โ€” unique in the air purifier industry, but it does require you to sign up for their filter subscription. We have already reviewed the Alen 75i and 45i, which impressed us, although they are a little pricier than competitors with similar air cleaning performance. 

The Alen Breathsmart Flex is based on the 45i but lacks the ionizer and smart features. It still has a similar level of air-cleaning power and looks very similar. We were keen to test the performance of the Breathsmart Flex in our home and see if it matched the performance of the Alen 45i.

Most air purifier reviews are just pictures and overly optimistic write-ups. Journalists at these publications are biased to sell the unit without digging deeper than running the air purifier a few times.  We donโ€™t have deals with manufacturers or a big corporation watching what we say, and we have no problem saying if an air purifier is terrible.

We donโ€™t just take manufacturers at their word, either; we test all our units in our home lab to see how well they remove particles and share this data directly with you.

Read our full testing methodology.

On paper, the Alen BreatheSmart Flex is very similar to the Alen 45i, although it lacks many smart features and an ionizer function. Read on to find out what differentiates these two Alen air purifiers.

Alen BreatheSmart

What we really like

Lower price for a similar CADR to the Alen 45i โ€” both units cleaned all PM1 pollutants from our test room in exactly 34 minutes.
Maximum of 50.7 dB at its highest speed, which compares favorably with other competing models with this CADR.
24.2 watts at its highest setting makes this one of the most efficient air purifiers we have tested and keeps long-term costs low.
Options to choose filters for specific needs such as those with higher levels of activated charcoal for more severe issues with VOCs, gasses and odors.
Lifetime warranty, which is something you only get with Alen air purifiers.

What we think could be better

No smart features such as App support or Auto mode โ€” you need to pay extra for the Alen 45i to get this.
Filter costs are higher with Alen, over $100 for the HeavySmoke filter that includes 2+ lbs of activated charcoal.

A fairly standard “Alen-looking” air purifier

The Alen Flex has a simple design and a small footprint considering its power.

You get a fairly standard Alen design with the Alen Flex, with a shiny white cover and a control panel on top. This is the same design you will see across other Alen devices in the BreatheSmart series such as the 45i and the 75i.

Alen BreatheSmart

It doesnโ€™t particularly stand out, but itโ€™s also unlikely to be something to start a conversation for the wrong reasons.

The control panel is simple and straightforward, in line with other air purifiers by Alen.

Alen BreatheSmart Flex Controls Alen BreatheSmart Flex VS Alen BeatheSmart

From left to right:

  • Filter indicator with three lights (green, yellow, red) to warn you when the filter needs to be replaced
  • Timer button to set the air purifier so it runs for 2, 4 or 12 hours before turning off automatically
  • Power button in the center to turn the unit on and off
  • Speed button to switch between fan speeds (with the highest being Turbo speed)
  • Lock button which allows you to lock the control panel after pressing and holding it for three seconds

Comparing the Alen Flex with the Alen 45i

If you have been researching Alen air purifiers for a while, you are likely to have run into another unit that looks A LOT like the Flex: the Alen BreatheSmart 45i.

When comparing the Flex to the 45i side by side, you will see that they both look as if they were to have been built from the same mold, with nearly identical design:

Alen BreatheSmart Flex VS Alen BeatheSmart 45i

Both the Alen 45i and the Alen Flex have many of the same features, such as the child safety guard and a removable front cover that can be swapped out for five different colors.

The biggest difference comes when you compare the control panel of both units side by side:

Comparing the Alen Flex VS Alen 45i

The control panel of the Alen Flex lacks buttons for the ionizer, auto mode and options for adjusting the light. 

That means that unlike the 45i, the Flex doesnโ€™t come in an in-built ionizer function (yay for those who prefer mechanical filtration only!) or with an auto mode (it does however come with a timer function, which is not the same but itโ€™s good to have).

Something worth noting: The Flex does not offer app support.

That said, you can connect your Alen Flex with the Alen air quality monitor, enabling you to understand your air quality and enable intelligent air purifier features. However, the monitor costs $129. 

Tip

If smart functions are important to you, you should consider going for the Alen BreatheSmart 45i instead as it will offer more bang for your buck.

High quality customizable filters 

As default you will get medical-grade H13 HEPA filtration, but you can choose different levels of carbon filtration as well.

Alen BreatheSmart Flex Pre Filter

As with all the Alen air purifiers, you will get to pick from four different options when buying your Flex:

B4-Pure FilterCaptures allergens, dust, mold, and germs
B4-Fresh FilterAll of the above + carbon to absorb common household odors 
B4-Odor FilterAll of the above + odor neutralizer to absorb pet odors and other unwanted smells 
FL40-H Heavy Smoke FilterAll of the above + 2.3 lbs of active carbon to absorb chemicals, VOCs and smoke

Every single Alen filter includes medical-grade H13 HEPA filtration that captures 99.9% of particles as small as 0.1 micron (e.g. dust, allergens, and harmful fine pollutants).

Alen BreatheSmart Flex HEPA Filter

That said, my recommendation would be to get at least the FL40 Filter, as it comes with 2.3 lbs of activated carbon that can help remove unwanted smells and dangerous gases from the air.

The additional cost on top of the basic B4-Pure Filter is not a lot, and you will get an activated carbon filter in addition to the H13 HEPA filter:

Alen BreatheSmart Flex Activated Carbon Filter CloseUp

But if you just want an air purifier for allergies and do not need gas or odor removal, you can save a little money with the B4-Pure Filter filter option.

Tip

As with many HEPA-based air purifiers, the filters for the Alen Flex arrive inside a plastic bag, so be sure to remove them from the wrapping before you use them. 

I was pleased to report that the Alen Flex filter had an ample red warning to remove the plastic, so I canโ€™t imagine anyone ignoring this. I wish more air purifier manufacturers would do this.

Alen Flex Filter Bag

Changing the filter in the Alen BreatheSmart Flex is pretty straightforward. You just need to remove the back panel and you will be able to access the filters. Check out the video below for a step-by-step guide:

The Alen Flex cleared our test room in 34 minutes

Thatโ€™s the exact same time it took the more expensive Alen 45i, which uses an ionizer!

As with all the reviews we produce at HouseFresh, we tested the Alen Breathsmart Flex in our test room, which measures 728 cubic feet. We burned an incense stick to simulate indoor pollution and used two Purpleair laser particle counter sensors to record how long it took for the Alen Flex to remove PM1, PM2.5 and PM10 particles from the air.

You can see the test results in the chart below:

As you can see, the Alen Flex cleaned our test room at the exact same speed as the upgraded Alen BreatheSmart 45i. It will be effective for small to medium-sized rooms. For those with large rooms, you will want to look at the much larger Alen 75i.

Noise levels test results, compared

As with the Alen 45i, the Flex is one of the quietest air purifiers we have tested here at HouseFresh. At its highest level, it hits a maximum of 50.7 dB(A), less than the sound generated by a standard refrigerator.

In comparison, many air purifiers with similar power levels can reach beyond 55 dB and the Mila and IQAir Healthpro Plus go up to 59.2 dB and 61.2 dB, respectively. One feature of Alen air purifiers is that they also utilize pink noise, which is meant to be even more sleep-friendly white noise. 

We know noise can be subjective, so here’s a video to allow you to hear the different noise levels associated with running the Alen Flex across each of the available fan speeds:

The cost to run an Alen Flex: $83,23 per year

This calculation assumes you will stick to OEM filter replacements from Alen.

1. Electricity costs = $25.23 per year

Even at the highest speed, the Breathsmart Flex only pulled 24.2 watts, which is MUCH LESS than many competing air purifiers with this level of air cleaning performance. This means you can leave this unit on without worrying about large energy bills. 

2. Filter costs = $58.00 per year

The Breathsmart Flex uses the same filter choices we see with the Alen 45i, and on average, they are a little higher than we see from budget brands like Levoit or Taotronics. For those looking for large amounts of activated carbon, you will also have to pay a little more as these filters cost more than the Pure version. 

If you donโ€™t mind choosing non-Alen filters, you can get generic filters that cost $45.99 instead of $58 to reduce this cost a little.

Bottom line: Should you get an Alen Flex?

The perfect option for Alen fans who don’t want ionization technology and who don’t care about smart features.

The Alen Flex is the cheapest Alen air purifier sold. They can sell it at a lower cost than the Alen 45i as it lacks the ionizer and smart features. The Flex still benefits from the high level of air cleaning performance, filter options and lifetime warranty that all Alen brand air purifiers benefit from.

Alen BreatheSmart Flex Living Room

If you donโ€™t mind giving up the smart and auto mode for timers, then the Alen Breathsmart Flex is an air purifier that will do an excellent job keeping small-medium-sized rooms clean. It doesnโ€™t create too much noise and has very low energy consumption.

Shark HP102 review

Shark HP102 Kitchen Counter

Youโ€™ve most likely heard of the other SharkNinja products โ€” the parent company for this air purifier. Theyโ€™ve had $3.7 billion in sales across their products, including vacuum cleaners, air fryers and blenders. 

Shark HP102 Kitchen Counter

Their air purifier range is relatively new, first hitting the market in June 2021 but, as a company, they have been making other electronic products since 1994. 

The main focus of the Shark air purifier range is the Nanoseal HEPA that blocks 99.98% of particles as small as 0.1-0.2 microns, which is similar to the U.S. standard HEPA H13 filter (99.5% of 0.3 microns). 

The onboard sensor shows you the current level of air quality and can be switched into auto mode, which adjusts the fan speed based on current indoor air quality issues. 

Its main competitor is the smart Levoit Core 300S, also suitable for a similar-sized room. The 300S has a little more CADR but doesnโ€™t have the high-end screen you get with the Shark HP102.

TL;DR The lowdown on the HP102

Danny Ashton HouseFresh

โ€œSharkNinja has entered the air purifier market with the HP102, clearly targeting the same segment as the Levoit Core 300S.

With comparable CADR, auto-mode and just a 10-gram difference in weight from the Core 300S, we expected less performance due to lower CADR. Despite its low CADR, its air-cleaning performance was impressive and completed our smoke removal test quicker than the Core 300S.

The Shark HP102 screen offers a clear, constant view of indoor air quality, which I prefer over the Core 300S. If you’re seeking a compact room air purifier, the HP102 deserves your consideration.โ€

If you’re on a rush or just like to read the summary more than the whole thing, then this section is for you.

What we really like

Two minutes faster than the Levoit Core 300 to clear our test room.
High-quality screens for both the display and the control panel.
The air quality sensor adjusts very quickly to detect pollutants.
High-end build quality โ€” similar to other products by the company.
Lots of cheaper generic filters available.
It would provide a good level of air changes per hour for spaces less than 219 sq. ft.
Very impressed with their manual โ€” itโ€™s packed with lots of great tips to get the best out of your HP102.

What we think could be better

The advertising of 500 sq. ft. is too big a space, at least half this.

I will go into it in more detail further down the review but in the photo below you can see how the two units look when compared side to side: 

Shark HP102 VS Levoit Core 300S

You can see the difference the display screen makes to the overall look when you place it next to the Core 300S. The HP102 looks a lot more modern, making it a better fit for those with smart appliances around the home. 

Between the display screen and the touchscreen in the control panel at the top, the Shark HP102 is a great air purifier for techy households:

Shark HP102 Display screen Control panel

Letโ€™s move on to the top control panel, which you can see in the photo below right on the edge of the air output vents:

Shark HP102 Control panel

The buttons are pretty straightforward – from right to left:

1. Child Lock: Press and hold for two seconds to lock (and unlock) the top control panel buttons. 

2. Filter Life: Press to show the remaining filter life. This button will flash to indicate when the filter needs changing.

3. Shut-Off Timer: Press to set the number of hours for the HP102 to run before it automatically shuts off.

4. Brightness: Press to dim the brightness of both the top control panel and the front display screen.

5. Air Info: Press to switch between air quality display options:

6. Auto Mode: When you press Auto Mode, the fan speed will automatically increase or decrease based on real time air quality readings.

โ€œAuto Mode is easy to engage and you can control the fans via the screen. The timer is a one-time choice. You can adjust the lights to be on or off, which is excellent for those wanting to keep it running at night, which I highly recommend.โ€ 
โ€” Danny Ashton, HouseFresh Founder & Senior Writer

7. Fan Speed: Press to adjust the speed of the fan, moving from 1 Low, 2 Medium, 3 High and 4 Maximum. Keep in mind that once you press the Fan Speed button, you will deactivate Auto Mode.

Understanding the air quality rings 

The circular air quality indicator on the display screen is the main highlight of the Shark HP102. 

When you turn on the HP102, its sensor will automatically analyze the air quality in the room. Once it’s done, you will be able to see the current air quality with a colored ring on the display:

๐Ÿ”ต
GOOD
A blue ring means your air quality has a low level of particle concentration (0-25 particles per cubic meter)
๐ŸŸ 
FAIR
An amber ring means your air quality shows a moderate level of particle concentration (26-80 particles per cubic meter)
๐Ÿ”ด
POOR
A red ring means there is a high level of particle concentration in the air (81-430+ particles per cubic meter)

The screen is easily understood and adjusted quickly when we conducted the incense smoke test in our test room:

Shark HP102 Air Quality Sensor

An unexpected great: The air quality sensor on board the HP102 measures PM1, PM2.5 and PM10. All the figures matched what we saw with our PurpleAir Indoor sensor, which uses laboratory-quality air sensors. 

๐ŸŒฟ Once your HP102 reaches the 100% clean air status (when running on Auto Mode), the air purifier will enter Eco Mode to optimize the filter’s life.

NanoSealโ„ข technology that supercharges the HEPA filter

The filters are tested to IEST-RP-CC007.3, 0.1-0.2 microns, which makes them unique. But they do seem very similar to the popular HEPA H13, which we see used by Levoit and other brands. 

Shark HP102 Filter Top View

When you pick up the filter, you can tell itโ€™s well-made โ€” it feels like it will last longer than the cheaper feeling filters from Blueair (below a photo of the filter inside the Blue Pure 411+ to make my point better:

Blueair Blue Pure 411 HEPA Filter

Now, the photo I used at the top is a bit misleading as when you look at the filter in the HP102 from above, it looks like any other cylindrical air filter. But everything changes when you look at the filter from the front:

Shark HP102 Unit Next to Filter

This is not your typical HEPA filter. The Shark HP102 comes with a unique type of air filtration technology: the Shark NanoSealโ„ข filter. 

Shark HP102 Filter

Upon reading about this filter, I learned that it is a True HEPA multi-filter with a Microbanยฎ coating that inhibits the growth of bacteria on the surface of the filter.

The activated charcoal space is more significant than what you get with the Levoit Core 300S and it looks like pelletized activated carbon VS integrated charcoal fabric. For severe odors, though, you should look at air purifiers that use more activated charcoal, like the ones on our list of the best air purifiers for VOCs.

Tip

The filter in the HP102 is not washable, so keep it away from water. Something you can clean is the exterior and the interior of the unit itself. SharkNinja recommends that you do so every two months, using a microfiber cloth or a vacuum cleaner to remove dust and debris.

Replacing the filter in the Shark HP102 is a simple process. Something to remember is that as soon as you have installed the new filter, you need to press and hold the Filter Life button for 3 seconds in order to reset the filter life percentage.

I found a great tip inside the HP102 manual that I think is worth sharing:


Shark Logo

โ€œTo maximize the life of the filter, reorient it every three months: remove the filter, turn it upside down, then reinsert it, making sure that the side that was previously on top is now on the bottom.

This will help equalize the distribution of captured particles throughout the filter, helping to extend its useful life.โ€

– SharkNinja team


Remember that all new HEPA-based air purifiers will come with filters in plastic bags, so make sure to remove them before you turn on the air purifier. 

The Shark HP102 cleared our test room in 38 minutes

Based on the stated CADR, we expected less but were very happy to see this air purifier perform well in our home lab test.

Shark HP102 Testing

As part of this review, we filled a 728 cubic ft office with tiny particle pollutants caused by burning incense and tracked how fast our air purifier can clean the air. Our tests mean we can look beyond manufacturer data and identify which air purifiers are worth your consideration.

Air cleaning performance test results

It took the Shark HP102 38 minutes until our air quality sensor showed 0PM1. This is just above the Levoit Core 300 but longer than the Levoit Core 300S and the Alen BreatheSmart Flex.

This is a good level of cleaning power for the price โ€” the fact it also includes an air quality sensor provides additional value.

Noise levels test results

It has slightly lower sound levels than the Core 300S both at the lowest (63.1 dB VS 38.9 dB) and top (52.2 dB VS 54.5 dB). Overall, it compares favorably compared to several units. 

But you can listen for yourself to the different sound levels in our YouTube video below: 

The cost to run a Shark HP102: $61.15 per year

1. Electricity costs = $31.15

This unit only showed 20.42 watts at the highest speed, so it wonโ€™t hurt the energy bill too much โ€” it would only cost $31.15 to use all the time, 24/7, for a year.

2. Filter costs = $30.00

SharkNinja says you can go up to 12 months without replacing the filter, but genuine filters are currently hard to find on Amazon. 

Luckily, there are many generic filters for sale, so you can run this air purifier for less than $30 per year for new filters. The Levoit Core 300S has similar generic filters that cost $34 yearly for two filters every six months.

Overall, energy and filter costs are lower than other budget air purifier brands.

Okaysou AirMax 10L Pro review

Okaysou AirMax 10L Pro Living Room

Okaysou has been around since 2018 and, according to Linkedin, only has eight employees, mostly based in China. I became aware of their air purifiers when they started ranking among the most popular units sold on Amazon. 

They have also been marketing heavily, with TikTok posts showing how their air purifiers catch pollutants in the home.  

TikTok Okaysou

The AirMax 10L (available since December 2020) is a larger update to their popular AirMax 8L. It has a 5-in-1 filter system that combines different filters, including a rare ionic silver filter and two H13 filters. 

Since 2022, the team at Okaysou has sent our team no less than eight messages asking us to join their affiliate scheme and receive a free air purifier. We never accept free air purifiers, though. We bought the AirMax 10L with our own money, so you can be sure this review will be honest and unbiased.  

We also donโ€™t rely on what manufacturers say; we test all the units we review by analyzing how quickly they remove the smallest particles from the air. We can compare performance across brands and models by testing all our air purifiers in the same-sized space.

How we test air purifiers

Read our full testing methodology.

UPDATE 2024: Okaysou Corporation has declared bankruptcy

For those who own one of their units, some generic filters are still available on Amazon, but we don’t know for how long.

In 2022, Arovast Corporation and Etekcity Corporation (owners of the trademark Levoit) presented a patent lawsuit against Okaysou. They argued a design patent infringement on Okaysouโ€™s Cayman 608 (which looks A LOT like the Levoit Core 400S) and Apollo 718 (a copy of Levoit Vital 100).

Levoit Vs Okaysou

Almost a year later, Okaysu Corporation declared bankruptcy by filing a Chapter 11 voluntary petition. This is known as a “reorganization” bankruptcy because the company is allowed to continue its operations while it develops a plan to repay its creditors. 

The case then took a turn when Amazon joined forces in a Conversion Motion, which is a request to convert the reorganization bankruptcy into a โ€œliquidationโ€ bankruptcy. Liquidation, Chapter 7 of the Bankruptcy Code, means selling the companyโ€™s assets to pay off its debts. 

In December 2023, they achieved it: the court decided to convert the case to Chapter 7. Okaysouโ€™s website is currently down, and thereโ€™s no official Okaysou store on Amazon, either. The company’s prospects donโ€™t look good at all. 

Tip

If you own an Okaysou air purifier, I recommend buying filter replacements in bulk if you find them to ensure you can still use your device for a little longer.

Looks like a Levoit and Alen had a baby

This unit resembles the Levoit Vital 100 and takes many design features from other units like the Alen 45i. It also looks very similar to the Coway Airmega AP-1512HH

Okaysou AirMax 10L Pro Front

Itโ€™s fair to say that the designers at Okaysou took inspiration from the best-selling units made by major air purifier brands in designing the AirMax 10L.

In the photo below, you can see the AirMax 10L Pro side by side with the Levoit Vital 100:

Okaysou AirMax 10L Pro Levoit Vital 100 Comparison

The design is not a total rip off but the front panel of the Okaysou AirMax 10L Pro does bear some resemblance to the front panel of the Levoit Vital 100.

Things change when looking at both units side by side:

Okaysou AirMax 10L Pro Levoit Design Comparison

When looking at the Okaysou AirMax 10L Pro profile, you can see that itโ€™s reminiscent of the air purifiers designed by Alen:

Okaysou AirMax 10L Pro Alen 45i Comparison

As you can see, itโ€™s much smaller than the Alen 45i but it does feel like a little sibling. Even the air quality sensor is on the same side of the unit:

Okaysou AirMax 10L Pro Sensor

The air quality sensor is the main smart feature available on the Okaysou AirMax 10L Pro. The sensor changes color depending on the current level of indoor air quality. This feature allows you to enable auto-mode, a fan mode where the air purifier will automatically adjust fan speed levels based on the level of pollutants detected in the air. 

In addition to the auto-mode, the AirMax 10L Pro includes four timer settings, a child lock, three fan speeds, and a filter rest light.

Okaysou AirMax 10L Pro Controls

You donโ€™t get fancy touchscreens with the Okaysou AirMax 10L. Instead, you have four buttons that do everything. 

โ€œ5-in-1 Purification Systemโ€ that doesnโ€™t match our expectations

Most air purifiers use a combination of HEPA and activated charcoal to remove gasses and particles from the air. 
According to marketing materials, the Okaysou Airmax 10L Pro is โ€œequipped with 5-in-1 purification system, washable dual-filter, nanois-Fflter, and honeycomb activated carbon filterโ€.

Okaysou AirMax 10L Pro Marketing

Based on the image and the description above, I was expecting a sizeable pre-filter, two HEPE Filters, one โ€˜blue nanois filterโ€™, and an activated carbon filter. I kept looking inside the box because all I received was the following:

Okaysou AirMax 10L Pro All Filters

That said, I was pleased to see a honeycomb filter with active carbon pellets instead of the impregnated fabric you sometimes get in other budget air purifiers.

However, I believe this is misleading advertising. The H13 HEPA filter they show in their marketing materials in between the โ€˜Advanced Blue Nanois Filterโ€™ and the activated carbon filter is not, in fact, two separate filters but just one that is blue on one side and white on the other:

Okaysou AirMax 10L Pro All Filters 2

A simple fix to the marketing materials would be to use a similar visualization as Okaysou uses in the user manual of the AirMal 10L Pro:

Okaysou AirMax 10L Pro Manual

The diagram above makes it clear that the nanois filter and the โ€˜premium filterโ€™ are one thing, not two.

One thing I noticed when I first got the filters out was how thin they were โ€” the activated carbon filter was less than 1 cm wide. 

Just to put this into perspective, here is a comparison shot showing the filter of the Alen BreatheSmart Flex side by side with the filter of the Okaysou AirMax 10L Pro:

Okaysou AirMax 10L Pro Filter Comparison with Alen Flex

Another issue I found is the low quality of the pre-filter. 

The pre-filter is attached to the HEPA using velcro, but when I tried to detach it for the first time, the glue became unstuck, leaving it to flap:

Okaysou AirMax 10L Pro Pre Filter Break

When it comes to the filtration technology in the Okaysou AirMax 10L Pro, the unit comes with a unique filter called โ€œAdvanced Blue Nanois Filterโ€. It is a HEPA filter treated with silver ions, which are bioactive agents that can kill bacteria, viruses and other microorganisms.

Okaysou AirMax 10L Pro Blue Nano Ionic Silver Filter

While there has been evidence that using a filter coated with silver ions can help reduce bacteria levels, there is also evidence of the toxic effect of silver ions and silver nanoparticles towards human cells. 

Compared with other similarly designed air purifiers, there is a little gap on each side of the filters when they are sitting inside of the unit. I prefer a tighter fit to avoid air bypassing the filter.

Okaysou AirMax 10L Pro Open

Accessing the filters is not difficult at all. Here is a video showing you what to do:

Tip

As with all brand-new air purifiers, the filters for the Okaysou AirMax 10L will come in plastic bags. Make sure to remove them before you switch it on, or they wonโ€™t be able to do anything to remove pollutants from your air. 

After testing the unit and going through the filter’s performance, I would have liked Okaysou to include one large H13 HEPA filter and a more robust activated carbon filter. 

I disagree entirely with their marketing message that their 5-in-1 system is 40% better by using multiple filters. But more on that in the next section of my review, where I review our performance test results.

The Okaysou AirMax 10L cleared our test room in 42 minutes

Like all the reviews we publish here at HouseFresh, we put the Okaysou 10L through our performance test: The results were disappointing. 

Okaysou AirMax 10L Pro Test

In our 728 cubic ft home lab, we simulate particle pollution and VOCs with an incense stick and use a Purpleair Indoor Sensor to monitor particulate levels. We then activate the air purifier at its maximum speed and measure the duration required to reduce the room’s air quality to a PM1 level of zero.

This is what happened when we performed this air cleaning test on the Okaysou AirMax 10L Pro:

Air cleaning speed, compared

With a CADR of 147 CFM, we expected it to clean our room quicker than the Levoit Core 300, but it took four more minutes.

Compared to the Blueair Blue Pure 411+, the difference between CADR and real-world performance is even starker; the Blueair 411+ has a CADR of 121 CFM yet managed to clean our room in one minute less. 

I fail to see how Okaysou can give this air purifier a recommended room size of up to 1000 sq ft. This unit is way too underpowered for such a large space, so it is likely to be unable to clean the air once an hour.

Noise levels, compared

At 55.6 dB at its highest speed, this aligns with other units at this price point and air cleaning power, such as the Levoit Vital 100 at 55.3 dB and the Medify 25 at the same level of 52 dB. 

As usual, we have also recorded a video so you can hear the sound with your own ears as noise levels can be a subjective thing:

The cost to run an Okaysou AirMax 10L: $188.44 per year

1. Electricity costs = $88.54 per year

Rising energy costs are unlikely to go away soon. So these costs must be considered when looking at a device that you want to run continuously, like an air purifier

We saw 58.05 watts at its highest fan speed โ€” much higher than we expected for this cleaning performance. I imagine including the extra filters means the fan must work harder to push air through them effectively. 

In comparison, the Blueair 411+ cleaned our room one minute quicker and only pulled 10.4 watts. 

So, from an energy usage standpoint, the Okaysou AirMax 10L is much poorer when compared to other similar air purifiers. 

2. Filter costs = $99.90 per year

Mechanical filter technology uses HEPA and activated carbon to capture particles and gases that, over time, are held in the filter material. After some time, the filter will become so full of pollutants that you have to replace them to sustain cleaning performance. 

Okaysou recommends changing the filters every six months for the AirMax 10L and genuine filters are available for $49.95, equating to nearly $100 per year

This cost is less than the Dyson range of air purifiers and high-end units like the IQAir Healthpro Plus. But it is higher than the genuine filters for the Levoit Core 300 ($39.99.)

As with Levoit, Amazon does have several non-genuine filter options for less than that, which bring the yearly cost down by half, with two filter sets available for $52.99.

Bottom line: Should you buy an Airmax 10L Pro?

The Okaysou AirMax 10L Pro is an overly-marketed product that doesnโ€™t live up to the hype

In my opinion, Okaysou contacted us many times because they wanted us to write an overly optimistic review. Itโ€™s clear that they are experts in marketing, but the AirMax 10L is not an air purifier I would recommend. 

While itโ€™s pretty cheap, $199.99-$149.99, you still get better air cleaning performance with the $99 Levoit Core 300

I donโ€™t like how they present their filter process as 40% better than standard methods. If anything, our tests showed that it has less air-cleaning power than standard HEPA and activated charcoal.  

I have been around the world of air purifiers for 20+ years, and itโ€™s a regular occurrence that a new brand comes to market with many promises and a price that is easy to digest. 

Okaysou AirMax 10L Pro Fireplace

Sadly, the Okaysou, while not the worst air purifier we have tested, fails to match its marketing promises and for that alone, I would not recommend it. 

Instead, I would recommend the Levoit Core 300 and Blueair 411+ as they clean the air quicker for less money. They cost less initially and in the long term and come from a brand that doesnโ€™t bend the truth to sell more units.

Moiswell Defender MP70 145 pint dehumidifier review

Moiswell 145 Pint Dehumidifier Side

Moiswell is a specialist dehumidifier brand that produces large crawl space and commercial dehumidifiers, from 145 pints to 320 pints per day.

According to their website, the Moiswell brand belongs to Hongkong lnofia Technology Co. Limited, a company registered in Hong Kong in 2022.

As with all the dehumidifier reviews we produce here at HouseFresh, we bought the Moiswell 145 pint with our own money and tested its water removal ability and performance over time. We often will update our reviews if things change, such as when our pump died on our hOmeLabs 4000 dehumidifier last month.

  1. We set up the dehumidifier inside our very humid basement of 2,000 sq. ft.
  2. We set up our trusted SensorPush wireless hygrometer to track humidity levels in the air every minute while the dehumidifier is running.

  3. We switch the dehumidifier on to its highest speed and record how long it takes to lower the humidity levels in our basement.
  4. We use an energy meter to measure precisely how much electricity is used when running the dehumidifier.

Its height is 13.3 inches, which is small enough for even the tightest crawl spaces.

Moiswell 145 Pint Dehumidifier Front

I am currently using it on my basement floor as I havenโ€™t got around to mounting it on my floor joists. It weighs 70 lbs (or nearly 32 kg), so I will need help from someone else to mount it.

That being said, I was glad to see Moiswell added handles at the top of the dehumidifier, making it easier to move around – yes, it is still heavy but the handle bars make picking it up A LOT less challenging.

Moiswell 145 Pint Dehumidifier Top

When I first unboxed the Moiswell 145 Pint dehumidifier, I immediately noticed how much smaller it is compared to the other residential dehumidifiers we tested here at HouseFresh. 

Just to show you one example, check out the hOmeLabs 4000 – a residential air purifier that is super popular right now:

hOmeLabs 4000 sq ft Living Room

PRICE on amazon

It looks nice but the honest truth is that the hOmeLabs 4000 would be way too big for any crawl space, so if youโ€™re looking for a dehumidifier for a tight space, then the Moiswell is your best bet:

Moiswell 145 Pint Dehumidifier Close up

The control panel is really straightforward. It has four buttons, one for switching on/off, two for adjusting the humidity target and a timer function, so you can set it up to work for a specific amount of time.

Moiswell 145 Pint Dehumidifier Controls

I have connected the Moiswell to a Philips Hue Smart Plug, which means I can treat it like another smart home gadget. This allows me to fit the Moiswell into my existing automated routines for the house, plus it means that I can turn the dehumidifier on/off from anywhere as long as I can access the internet.ย 

Tip

If you are into building a smart home, the Philips Hue system is a cheap way of turning any gadget into a smart appliance.

Washable filter with a pump and drain

All dehumidifiers need to keep dirt from entering the unit, as it can cause damage and lead to failure in the future. 

The Moiswell Defender MP70 avoids this by making the washable filter slide out easily for cleaning.

Moiswell 145 Pint Dehumidifier Side

After using this dehumidifier in my basement for two months, I have to say that the Moiswell has a good-quality filter. It is much better than what you get with most of the residential dehumidifiers we have reviewed. 

I look forward to using the internal pump. You can use the gravity drain to connect a hose that will flow if you donโ€™t go against gravity. 

Moiswell 145 Pint Dehumidifier Hose

With the pump option, you also have an internal pump that can move the water vertically up to 16.5ft, which is excellent for use in basements where the drain is often higher than the basement floor. 

The Moiswell 145 Pint dehumidifier also offers you the option of using an external pump, allowing you to move water anywhere, depending on the pump’s power. 

Itโ€™s worth noting that these commercial-style dehumidifiers save space by not having a water bucket, so you will need a hose to remove the water. There is no option just to have the unit collect internally.

I am excited to see how well the pump performs over the long term, as after less than 12 months, our hOmeLabs dehumidifier pump failed, and I saw that this happens quite a bit with residential-style units. 

๐Ÿค“ I have noticed that many of the more prominent brands (Honeywell and Frigidaire) donโ€™t have as many residential-style dehumidifier units with pumps, which might be due to returns. 

I hope this dehumidifier has a higher-quality pump and wonโ€™t fail me, but I will update this review if it does.

The Moiswell Defender MP70 lowered humidity levels in my basement within 24 hours

I tested the Moiswell Defender MP70 in my very damp basement built in the 1890s. This space regularly gets very damp, reaching up to 74.1% humidity. Since the hOmeLabs pump failed, my basement had accumulated a lot of humidity, so it REALLY needed drying out. This set the perfect conditions for a test.

I used the internal pump to move water to an external drain outside my basement and was glad there was no water bucket to change. It would likely need changing multiple times a day. 

To measure the humidity levels over time, I used my Govee WIFI humidity sensor that tracks current humidity every minute. Using this data, I can share below how the Moiswell 145-pint dehumidifier helped to reduce humidity levels to a comfortable level:

Noise levels test results

When running, the Moiswell 145 Pint dehumidifier generated up to 58dB, so you canโ€™t hear it on the ground floor. I liked that the sound was continuous as it helped to blend into the other sounds around. 

But sound levels are a personal thing, so feel free to check out the video of the Moiswell Defender MP70 running in my basement: 

The cost to run a Moiswell 145 Pint dehumidifier: $541.37 per year

Dehumidifiers use a process similar to air conditioners and can use much more electricity than expected. Itโ€™s a little tricky to measure the exact amount of electricity a dehumidifier will use, depending on the current humidity conditions and settings you set up. 

The dehumidifier must run harder to reduce the humidity if it’s very humid. When it reaches the target level, it will stop until the humidity levels increase again. 

When we tested the Moiswell 145 pint when it was in humid conditions, it pulled 514.96 watts, which, if we assume it will run for 24 hours per day every day of the year, will be $541.37 which I think is likely much higher than will be your usage but worth keeping in mind as these large commercial units do use a lot of energy.

Bottom line

I am impressed with how well the Moiswell Defender MP70 dehumidifier reduced the humidity in my 2000 sqft damp basement. The product looks well made, and while it doesnโ€™t have any smart features, I could make it smart by connecting it to my Philips Hue system. 

Moiswell 145 Pint Dehumidifier Basement

If you have a sizeable damp basement, this commercial unit would be a better investment in the long term, especially considering how many residential-style units with pumps fail. 

If any issues arise, I will continue to update this update, but as of now, this is a powerful, well-built unit for a price that makes it much more affordable than better, well-known brands.

Atmotube PRO Review

ATMO Tube Pro Car

Created by Atmo, a startup based in San Francisco, California, the Atmotube PRO is designed to send air quality metrics to your smartphone. The guys at Atmo reached out and asked us to test the device.ย 

We usually don’t accept products for review as we prefer to buy everything ourselves, but we decided to accept the offer from Atmo as were reassured that we could be 100% unbiased without the need to “soften the blow” if there was anything about the Atmotube PRO that we didn’t particularly like.

The Atmotube PRO is listed for $189.99 but can often be found for around $150. Most air quality monitors we have reviewed here at HouseFresh have a screen showing you the latest reading, but the Atmotube PRO sends all this information directly to your phone. 

The high-end sensor has been tested by the AQ-Spec, so I was eager to put the Atmotube PRO to the test.

TL;DR The Low Down on the Atmotube PRO


danny

“A unique product that enables your smartphone to tell you the air quality right now with data on PM1, PM2.5, PM10 and VOCs. Itโ€™s currently the only device on the market with a lab-level air quality sensor connecting directly to your phone. I would like to see improvements in the battery and app in future versions, but for those in high-risk areas, the Atmotube PRO is worth a look.”

โ€” Danny Ashton, Founder & Senior Writer


ATMO Tube Pro Front

 

If you donโ€™t want to read my full review, these are the key things you need to know about the Atmotube PRO:

What We Really Like:

๐Ÿ‘ It can provide readings every minute, so you can see if air quality is high risk in real time
๐Ÿ‘ The app can trigger alerts with different air quality scores
๐Ÿ‘ It is a small device that is easy to keep attached to your trousers or backpack
๐Ÿ‘ The Android app is intuitive and easy-to-use for first time users
๐Ÿ‘ The air quality sensor is highly accurate

What We Think Could Be Better:

๐Ÿ‘Ž The battery runs out quickly, especially when you enable updates every minute

The Specifications

The lab-level air quality sensor on this device gives you insight into VOCs. When you realize that this sensor doesn’t have a screen, it can seem expensive compared to the QingPing Lite, which is available for less than $100. 

However, the Atmotube PROโ€™s VOC sensor is a significant advantage over the QP Lite.

Small Device You Can Hang From Your Bag

The Atmotube PRO is a simple, elegant-looking black box. It weighs close to nothing so it wouldn’t be painful to hang it from your belt or a strap on your backpack.

Personally, I decided to hang it from one of the hooks in my car as I didn’t have an air quality monitor on the car yet:

ATMO Tube Pro Car

This is a very simple air quality monitor, so you should theoretically be able to get it to work right out of the box. That said, you’re likely to have to charge the device before you get to use it properly.

To fully charge your Atmotube PRO, you have to plug the USB Type-C cable to a power supply for a minimum of 2 hours. You will notice that the LED light on the device will change color from orange to green, this means that the Atmotube is charged and ready to go.

When it comes to controls, the Atmotube PRO device doesnโ€™t have much going on – just one button:

Atomotube PRO Controls

That’s right. This little device features just one button that you can press to see the current air quality score, which is indicated by the color of the LED light above the button:

Atomotube PRO AQI Colors

๐Ÿ’ก Pro Tip: The moment you switch on the Atmotube PRO, the device will immediately begin to measure air quality, but Atmo clarifies on the accompanying Quick Start Guide that their measurements become more accurate after the first 12 hours of use as this gives the Atmotube PRO enough time for a thorough calibration.

Simple and Straightforward Mobile App

As I mentioned in the introduction to this review, the Atmotube PRO sends detailed air quality information directly to your phone. The device doesn’t have a screen, so if you want to learn more about the air quality metrics other than what you can guess through the LED light colour, then you need to get the app.

Atmotube Pro Phone App

Two cool things about the app:

  1. It will immediate alert you when the air you’re breathing is not safe enough
  2. It saves historical data on the different air quality factors

Inside the Atmotube app, you can click on the different types of pollutants/factors to see historical data from hourly, daily, weekly, monthly and even over the year. This is possible thanks to the fact that the Atmotube PRO takes readings every few seconds while it’s ON. This is great but it really takes a toll on its battery.

In order to extend your Atmotubeสผs battery life, you can open the app and go to Settings. Once there, you can select one of the different Modes depending on how often you’d like the PM sensor to take its readings. I seriously suggest you do this.

Export Your Air Quality Data

You can export all the data you collect with the Atmotube PRO, including even the latitude and longitude of your location. 

I tested the Atmotube PRO during a visit to a BBQ restaurant. I assumed there might be a higher level of particulates in the air but was shocked to see how high the readings reached to. By seeing the alerts on my phone as soon as we stepped into the restaurant, I chose to sit further away from the kitchen near an open window.

Having the data reported every minute was very useful for reducing exposure quickly:


Bottom Line: High Price for a Unique Air Quality Monitor

If you are on the hunt for a cheap but accurate air quality monitor, you should consider the QP Lite. That being said, the Atmotube PRO has some exciting features that might be useful for some people. 

I liked that you can evaluate current air quality every minute. The app alerts give you a heads up when you’re in a situation where air quality has turned bad so you can do something about it. If you were biking or hiking in areas affected by wildfires, then the Atmotube PRO would quickly alert you that the air is polluted, allowing you to make a quick decision to get out of the area.

This pro, however, comes with a con: taking air quality readings every minute seriously reduces battery life. If you were to do this, the Atmotube PRO’s battery would last for about a day, meaning that the device could be out-of-battery by the time you really need it. 

ATMO Tube Pro Front

I am interested in future iterations of this device, especially if they come with a more powerful battery.

While we wait for smartphones to come with integrated air quality monitors (wouldn’t that be great?), the Atmotube PRO is the only way to access air quality readings in real time on your phone. 

Levoit EverestAir review

Levoit EverestAir Living Room

Levoit is one of the leading names in the air purifier space due to the popularity of its Core Series of air purifiers (the 200S, 300S, 400S and 600S). We have tested all of these air purifiers in our test lab, and they scored very nicely – especially considering they are often much cheaper than competitors. 

I first got an email from a reader asking about the Levoit EverestAir in October last year. We had many units scheduled for testing and review at the time, but the idea of a premium model from Levoit interested me, so I added the EverestAir to our list of upcoming reviews. 

While the Levoit Core series is all about performance, the EverestAir has the same level of performance in a much more unique and better-looking design. 

The EverestAir is currently the only model in this new category from Levoit. It comes with a high CADR of 360 CFM, meaning it can clean the air 4.5 times in a room sized up to 600 sq. ft. 

CADR isnโ€™t the only way to evaluate an air purifier, though โ€” our testing showed that the EverestAir performed better than units with a bigger CADR (more on that below).

how we test
How we test air purifiers

Read our full testing methodology.

All this to say, here at HouseFresh, we do not rely solely on manufacturers’ claims or suggest any air purifiers until we thoroughly evaluate them. 

Using our own testing data allows us to compare units like for like, so we can tell you whether you should go for it or just consider a better/cheaper alternative instead.

The lowdown on the Levoit EverestAir

Danny Ashton HouseFresh
โ€œI love the look of the Levoit EverestAir and was pleasantly surprised at how well it did in our performance tests. Itโ€™s official: this is the second fastest air purifier we have tested. The EverestAir removed tiny smoke particle pollutants and odors from the air in our test room in just 13 minutes. And it looked great doing it, making it worth the higher price.โ€

As always, let me start by sharing the main pros and cons I have identified for the Levoit EverestAir including findings from all my experiments and details from my experience using this unit at home for six months:

What we really like

It looks like an air purifier designed by Apple, which rivals the Dyson units.
It has the same app support as with the other high-end Levoit units.
The ability to adjust the vent angles is something that is unique to this model.
Amazing performance โ€” cleaned our test room in 16 minutes.
The screen of the onboard air quality sensor is clear and easy to understand.
It is nearly silent on the lowest fan speed AND still able to clean our test room in 25 minutes.

What we think could be better

The initial price is much higher than the Core 600S.
Filter costs are higher but do last longer than cheaper Core series units โ€” up to 15 months.
The little wheels at the bottom of the device only go in one direction, making it difficult to maneuver the unit.

If Apple designed air purifiers

The Levoit EverestAir broke the mold Levoit has gotten us used to, taking some inspiration from modern consumer electronics.

Levoit EverestAir Front Design

๐Ÿ’กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10

The design of most Levoit air purifiers is pretty standard and generally heavily inspired by existing lines. Looking at the Core series, youโ€™ll quickly grow bored of the same white, boxy look with rounded edges. 

But thatโ€™s not what the EverestAir is all aboutโ€ฆ

Levoit EverestAir Fireplace

When looking at the unit from the front, I immediately got Blast Mini vibes:

Levoit EverestAir Top Front

But all that changes the moment you turn the unit around and find a sleek silver back panel:

Levoit EverestAir Back

The design lines are reminiscent of what we like in the Dyson air purifier combo: a touch of futurism. The key difference here is that the EverestAir not only looks good, but it also does a fantastic job at cleaning the air. Point for Levoit.

Most high CADR air purifiers have to be big so that they can house the enormous fan. But the engineers at Levoit have managed to provide large CADR in a smaller body. Just to give you an idea of size, we took a photo comparing the EverestAir against the powerful IQAir Healthpro Plus:

Levoit EverestAir VS IQAir HealthPro Plus

The Levoit EverestAir has a much more manageable size, yet it performs at a high level. But I have to say that this is not a small unit. The good news is that Levoit gave it wheels to make it easier to move from room to room:

Levoit EverestAir Wheels

With the EverestAir, Levoit has brought the Apple design aesthetic everyone knows and loves to the world of air purifiers. 

I particularly like the combination of a white front panel with silver for the main body and the black glass-effect plastic used for the control panel:

Levoit EverestAir Controls

In terms of the controls available in the EverestAir, from left to right, you get touchscreen buttons for sleep mode, auto mode, turbo, fan speed, fan angle, timer and on/off button. 

In the middle of the panel, you will see a screen where you can display filter info (filter life % so you know when itโ€™s time to replace the filter) and also air quality information (PM1, PM2.5 and PM10 particles in the air).

Thatโ€™s right. Air quality info on your display.

The EverestAir comes with a three-channel laser sensor that detects dust particles of PM1.0, PM2.5 and PM10. 

Levoit EverestAir .AQI Sensor

We were impressed by how quickly the screen changed when we started burning incense next to it to release pollutants into the air. When we turned on the unit, we could quickly track the speed at which the EverestAir was cleaning the air:

Levoit EverestAir AQI Working

The best part? The air quality sensor in the Levoit EverestAir matched what we could see in our trusted PurpleAir Indoor Sensor, which uses an industrial-grade particle sensor. ๐Ÿ‘๐Ÿ‘๐Ÿ‘

Before I move on to discussing air filtration technology, I have to mention the Levoit VeSync mobile app. It is super handy to be able to add my new EverestAir to my already existing account, allowing me to control the settings of this unit in addition to all the other Levoits I’ve got placed in different rooms around my house:

everest smartphone screens

Filters that can deal with anything

Like other filters from Levoit, the 3-stage filtration technology in the EverestAir combines a washable pre-filter, a main filter and pelleted activated carbon. 

Levoit EverestAir UnitFilter

This large filter can deal with both pollutants and smells: 

Levoit EverestAir Replacement Filter

One side of this filter features a high-quality main filter to tackle the tiniest airborne particles:

Levoit EverestAir HEPA Filter

The other side features a honeycomb activated carbon filter:

Levoit EverestAir Activated Carbon Filter

I was very impressed by the filter’s size, quality and amount of activated carbon. 

For tackling odors or chemicals, you need a good amount of carbon in your air purifierโ€™s filter, so it is great to see such a large quantity of activated carbon pellets included in the EverestAirโ€™s filter.

Just to show how big the filter is, I took a comparison photo showing the size difference between the EverestAir and the IQAir HealthPro Plus:

Levoit EverestAir Filter VS IQAir HealthPro Plus Filter

During our performance test, we saw that the VOC levels were reduced much quicker than units with smaller levels of carbon: the EverestAir brought VOC levels back to baseline in 160 minutes โ€” it takes many other air purifiers most of the day to achieve this. 

Changing the filters on the Levoit Everest is easy as they are accessible from the front. You can see how easy it is in our video below:

As with all brand-new air purifiers, the filters for the EverestAir will come in plastic bags. Make sure to remove them before you switch them on, or they wonโ€™t be able to do anything to remove pollutants from your air. 

The EverestAir cleared our test room in 16 minutes

As with all the air purifiers we review here at HouseFresh, we timed how fast the Levoit EverestAir could remove incense smoke particles from the air in our home lab.

Levoit EverestAir Testing

๐Ÿ’กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10

In our 728 cubic ft home lab, we simulate particle pollution and VOCs with an incense stick and use a Purpleair Indoor Sensor to monitor particulate levels. We then activate the air purifier at its maximum speed and measure the duration required to reduce the room’s air quality to a PM1 level of zero.

This is what happened when we performed this air cleaning test on the Levoit EverestAir:

The results we saw with the Levoit EverestAir blew us away. We repeated the test three (3) times because we couldnโ€™t believe what we were seeing.

Air cleaning performance test results

We expected good results with a CADR of 360 CFM but assumed it would be the same as the Alen BreatheSmart 75i and certainly not faster than the Levoit Core 600S. 

But we were delighted to see even better air cleaning performance results than the CADR we expected:

Excellent air cleaning performance at its lowest fan speed

I didn’t stop there. In addition to testing the air cleaning performance when running at its top fan speed, I also ran the test at the lowest fan speed, and the EverestAir delivered: this air purifier cleared all traces of incense smoke in our test room in just 29 minutes.

When comparing the EverestAir against all of the other Levoit air purifiers we have tested, you can see how it clearly defeats most of them when it comes to air cleaning speed, only outbeat by the Smart Air Blast Mini (15 minutes):

For those with larger rooms or large ceilings, the EverestAir will be more than capable of keeping the air clean. However, I would still push for a specialist air purifier for significant issues like VOC or chemicals like the AustinAir Healthmate, as they have much larger carbon filters,

Noise levels, compared

It hits up to 57.8 dB using the Turbo mode but is much quieter at the lower fan speeds, going as low as 39.1dB, which sounds like no noise to my ear.

Donโ€™t just take our word for it, have a listen for yourself as we go through the different fan speeds in the video below:

The cost to run an EverestAir: $173.57 per year

The cost to run the Levoit EverestAir is similar to other large air purifiers like the Blue Pure 211+ and Alen 75i

When comparing the long-term costs associated with replacing filters and energy consumption, you can see

1. Electricity costs = $73.58 per year

Energy costs always seem to go up, so itโ€™s essential to be aware of the long-term costs as air purifiers, in most cases, will be run continuously to keep the air clean. The Everest hit 69.8 watts using its turbo at the highest speed and went down to 9.85 watts at the lowest fan speed. 

The energy usage is higher than that of other smaller units, but it makes sense when you consider the performance. It compares well with similar big units like the IQAir Healthpro Plus, which pulls a whooping 145.2 watts. 

When comparing wattage usage to performance, the EverestAir is one of the most efficient air purifiers on the market. 

2. Filter costs = $99.99 per year

Many smaller air purifiers need their filters replaced every six months, so they can quickly add up to nearly $100 per year. While the filters for the EverestAir are not cheap, considering you can replace them every 12-15 months, the cost is very much in line with even the budget air purifiers we recommend. 

This chart shows how the costs stack up against other Levoit air purifier filter replacement costs:

As of writing this review, you can get two filters for under $99.99 if you donโ€™t get the genuine ones from Levoit, bringing costs down to nearly $65.98 per year.

Bottom line: Is the Levoit EverestAir worth it?

The EverestAir comes with a premium price tag that will be too expensive for most, but you can usually find it on deal during Amazon Prime Day and Black Friday.

Levoit has been creating very efficient air purifiers that perform well for a reasonable price, and it makes sense that they would create something for the premium market. That is exactly what the EverestAir is: a premium product that competes with the likes of Dyson and Air Doctor.

Levoit EverestAir Living Room

๐Ÿ’กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10

On paper, the EverestAir is a high-performing device, so we expected it to perform well in our home lab tests. It is one of Levoit’s most expensive units at $499.99, but we predicted it would fall short of the Levoit Core 600S in terms of performance.

You will get more power for your money with the Levoit Core Series, but the EverestAir beats them hands down for looks. We tested running this air purifier at the lowest fan speed, and it still cleaned our room in 25 minutes at 39.1 dB โ€” which was silent to my ear. 

Itโ€™s an easy air purifier to live with, but it doesnโ€™t come cheap.

SOURCES

We calculated yearly costs associated with running the Levoit EverestAir 24 hours a day, 365 days per year utilizing the Appliance Energy Calculator developed by the U.S. Department of Energy using the national average of of $0.12/kWh as of June 2024.

Levoit Vital 100 review

Levoit Vital 100 Kitchen

Levoit has earned quite a reputation in the air purifier space. Launched in 2016 by Vesync Co. โ€” a publicly traded Smart appliance company, Levoit has changed people’s perception of “cheap air purifiers,” offering features you’d expect in premium models at a fraction of the price. 

At only $96, the Vital 100 is an excellent choice for those looking to clean small-medium-sized rooms, with a unit that packs powerful filters. 

It is designed for rooms of up to 300 ftยฒ and based on its reported CADR and our tests, it is more suited to smaller spaces. 

Its main competitors for your dollars are the Levoit Core 300 and PUR 131, which we reviewed last year.

Levoit Vital 100 Utility Room logo

PRICE on amazon PRICE on LEVOIT

Short on time? Here’s our summary of the Levoit Vital 100. 

What we really like

It costs less than $100, sitting in the budget category
3-stage filtration that has a pre-filter, activated carbon pellets and a main filter
No use of ionizer, so zero byproducts created, such as ozone
Modern-looking design that wonโ€™t look out of place in a modern home
Easy to use with handy features like preset timers and filter replacement indicator

What we think could be better

A good looking unit with simple controls

The Vital 100 feels premium with a stylish look that complements home dรฉcor.

Its design is closer to that of the Levoit LV-PUR131 than the Levoit Core series, but I kind of like that โ€“ weโ€™ve got enough cylindrical air purifiers at home.

Levoit Vital 100 Front

The Levoit Vital 100 is a good-looking air purifier and is an easy unit to live with. It is compact, with a simple, glossy shell and rounded corners. Levoit offers this unit in two finishes โ€” white and gray. 

The Vital 100 only weighs 9.8 pounds, so you can easily carry it from room to room as needed. Even though the Vital 100 has a small footprint, it is less compact than the Levoit Core 300:

The control panel is at the top of the unit, similar to every other Levoit air purifier, so that is where you will find the different touch-LED buttons and indicators. 

Levoit Vital 100 Top

Levoit has included the following controls with this unit.

  • Power ON / OFF
  • Speed (for adjusting the fan speed)
  • Display (for adjusting the display light)
  • Timer (2, 4, or 8 hours)
  • Filter (for filter change notifications)

Each control comes with an icon and text label, making it even easier for a first-timer to operate the device. Blue LED lights are above the “Timer” and “Speed” buttons, so you can easily see your current setting.

Levoit Vital 100 Controls

The Levoit Vital 100 can’t be controlled via a smartphone. If these features are important to you, check the newer model, the Levoit LV 100S, which offers advanced features like Wi-Fi connectivity and smartphone support.

Tip

Keep in mind that smart functions will come at a higher price premium of $139.99 for the same level of cleaning power.

Powerful Levoit filters

Before purchasing any air purifier, it’s essential to know what filters the unit uses and how effective they are in cleaning specific contaminants in your home. 

The Levoit Vital 100 has a three-stage filtration system that tackles particulate at all levels. 

Fine washable pre-filter โ€” a washable filter that traps hair, pet fur and lint

Levoit Vital 100 Pre Filter

Main filter โ€” filters particles down to 0.3 microns, like dust, mold, pollen, dander and airborne germs but also does a great job of removing smaller particles than 0.3 microns, like viruses.

Levoit Vital 100 HEPA

Activated Carbon filter that uses pellets โ€” Absorbs VOCs and odors. I was pleased to see Levoit use pellet carbon versus the impregnated fabric you see with other brands use in activated carbon filters.

Levoit Vital 100 Activated Carbon Filter

The three-stage filtration system ensures that the system traps virtually all particles. You can quickly clean the pre-filter using a brush to remove any particle build-up, which helps increase the filter’s performance and lifespan. 

Levoit Vital 100 Filter details

Levoit has now removed the use of the term True HEPA or H13 for their filters when Dyson made a complaint to the BBB. Our test still showed that the level of filter they used was able to clean all pollutants of particles sized 1 micron or less. But until Levoit updates us, we won’t know the exact filter grade used.

Levoit recommends you replace the filters on the Vital 100 every 6 – 8 months. You don’t have to watch the calendar; the filter icon will illuminate when it’s time for a replacement.

Replacing the filter is simple. Just follow these easy steps:

  1. Unplug the unit 
  2. Remove the front panel by pulling it (it’s magnetized, so you don’t need to unclip anything) 
  3. Pull out the old filter using the tabs and remove the pre-filter, which is attached by velcro (this is the perfect time to give that a clean)
  4. Attach the pre-filter to the new filter and insert it the same way you removed it.
  5. Re-attach the front panel.

When you first receive your new air purifier, the filter will be in a plastic bag that needs to be removed before you start the machine. Otherwise, the air purifier will move air around the room, potentially worsening the air.

The Vital 100 cleared our test room in 49 minutes

At HouseFresh, we research CADR ratings and other metrics the manufacturer provides but don’t leave it at that. We perform our own thorough tests to see whether the unit performs as advertised. 

To test air purifiers in the real world, we utilize our home office, which measures 728 cubic feetโ€”roughly the size of a medium-sized bedroom. We burn incense sticks to fill the room with pollutants and use our indoor air sensor from Purpleair to see how quickly each unit can eliminate PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3 particles from the indoor air. 

We keep these conditions constant for all tests, allowing us to compare different air purifiers and see which performs best in removing indoor pollutants. 

So, how did the Levoit Vital 100 perform?

We were impressed by the performance of this unit, considering its price tag. It took the Levoit Vital 100 just 49 minutes to clean the air in our test room.

Air cleaning performance compared to other air purifiers

To put the test into context, check out how the performance of the Levoit Vital 100 compares to other units weโ€™ve tested:

Additionally, the Levoit Vital 100 is an incredibly quiet device. 

Noise levels test results

In our test, the unit produced 50 decibels of noise at maximum fan speed โ€” considered ultra-quiet by industry standards. The IQAir Healthpro Plus hits 69dB at its highest speed.

The cost to run a Levoit Vital 100: $134.13 per year

1. Electricity costs = $70.15 per year

The long-term costs of using an air purifier are essential, especially with the rising cost of electricity worldwide. The Levoit Vital 100 is not the most power-efficient unit we’ve tested, but it’s pretty efficient by industry standards. 

At the maximum speed, the unit pulled 45.99 watts, equating to $70.15 per year at 24/7 daily usage.

In comparison, the newer Levoit Core 300S cleaned quicker at 21.8 watts, and even the older Core 300 was 35.5 watts at its highest speed.

2. Filter costs = $63.98 per year

Another important factor to consider when buying an air purifier is filter costs. HEPA filters are the most effective at trapping indoor pollutants. Generally, replaceable HEPA filters should be replaced every six to twelve months. 

Levoit Vital 100 filters cost $31.99 for genuine filters, which is $63.98 per year in filter costs and you can find generic filters for $35.80 per year with two changes, which is a much better choice for most people. In comparison, genuine filters for core 300 are $79.98 per year and $39.99 for generic filters. 


Bottom line

The Levoit Vital 100 is an affordable, high-performing air purifier that cleaned our test room of all pollutants in just 49 minutes. Its filter costs are reasonable due to the availability of generic filters, and it’s certainly not worth upgrading if you have this air purifier, as it performed well in our particulate test. 

Levoit Vital 100 Kitchen

The Levoit Vital 100 is getting a bit old in air purifiers. While it delivered good results in our test, you will get better performance for your spend with something like the Levoit Core 300 for the same price or the upgraded Levoit Core 300S (for a little extra cost initially.)

SOURCES

We calculated yearly costs associated with running the Levoit Vital 100 for 24 hours a day, 365 days per year utilizing the latest average energy prices as reported by the Bureau of Labor Statistics of $0.174/kWh as of April 2024.

De’Longhi DEX214F dehumidifier review

DeLonghi DEX214F Living Room

The main use case for this dehumidifier was to keep my growing tent free of excess humidity – I didnโ€™t want to have something that took a lot of space but I also needed a unit that I could trust to deal with a large amount of humidifier as it would be located in our basement.

I will be honest, DeLonghi is not a brand I expected to run into in regards to dehumidifiers, as they are normally known for their coffee machines. But I read about the company and learned that they have significant history manufacturing heaters and air conditioners, so it makes total sense that they would move into the world of dehumidification.

As with all our hands-on reviews here at HouseFresh, I bought this unit with my own money, so I have no biases to give a better review than I would under normal circumstances. I also completed a series of tests in my own basement to assess the performance of the De’Longhi DEX214F in real-life conditions.

  1. We set up the dehumidifier inside our very humid basement of 2,000 sq. ft.
  2. We set up our trusted SensorPush wireless hygrometer to track humidity levels in the air every minute while the dehumidifier is running.

  3. We switch the dehumidifier on to its highest speed and record how long it takes to lower the humidity levels in our basement.
  4. We use an energy meter to measure precisely how much electricity is used when running the dehumidifier.
    How we test dehumidifiers Sound
  5. We track sound levels emitted by the dehumidifier with the help of our sound meter.

Right, let’s break down my first-hand experience using the De’Longhi DEX214F dehumidifier. I have been using this unit since September 2021, so I feel confident to give both a short-term and medium-term review of my experience.

The lowdown on the De’Longhi DEX214F

Danny Ashton HouseFresh
โ€œThe De’Longhi DEX214F is a mid-priced dehumidifier and can deal with 14 liters of water in a 24-hour period. If you are looking for a premium dehumidifier for a small to medium-sized room and are based in Europe, you should consider getting a De’Longhi DEX214F.โ€
โ€” Danny Ashton, HouseFresh Founder & Senior Writer
delonghi dehumidifier header

What we really like

Super simple control panel which makes it impossible to get wrong – this is not something you see very often in the world of dehumidifiers
The design is sleek and would pass the partner test for a unit that had to be used in a living room or hallway
High-performance, quickly removes humidity and the on-board sensors kick in quickly once humidity increases, so less power usage vs 24-hour full power
Good size for smaller rooms

What we think could be better

It felt cheap to use such a small amount of space for the โ€œallergen filterโ€
No option to get a model with a on-board pump

Clean design lines in a compact size

I know that looks are not the main focus for most people but it is something we like to assess when we know that a unit is going to be in a room all the time.

DeLonghi DEX214F Living Room

The Italian heritage is clear with this dehumidifier. The design of the De’Longhi DEX214F is a lot more aesthetically pleasing than most dehumidifiers we have tested. 

With its pearly white color and curves, the DEX214F breaks the mold used by other manufacturers who tend to release boxy dehumidifiers that are heavy and difficult to maneuver.

The handle is built into the main part of the unit, making it easy to move the dehumidifier from room to room if you need to do it. This is made even easier thanks to the low weight of this dehumidifier (only 24.9 lbs/11.3 kg when the tank is empty).

Unlike bigger units, it does not include a wall mount, so you can only use your De’Longhi DEX214F in cases where you have space to place it on the floor.

I doubt anyone is going to buy this dehumidifier for looks alone, but it is great to see the care De’Longhi took to make this unit look good when compared to the competition.

Another aspect of design that I always like to review is the control panel. After using the DEX214F at home for over six months, I am happy to report that this is one of the simplest units I have come across in terms of menu options.

DeLonghi DEX214F Control Panel

๐Ÿ’ง๐Ÿ’ง๐Ÿ’ง Approximately 40% environment humidity

๐Ÿ’ง๐Ÿ’ง Approximately 50% environment humidity

๐Ÿ’ง Approximately 60% environment humidity

The DEX214F also comes with a DRY mode ๐Ÿ‘•, which is very handy for speeding up the drying of laundry as it sets the dehumidifier to run at its top speed for a short period of time.

You will also get two indicator lights: one to let you know when the tank is full and another one to indicate that the room temperature is too low so the unit is operating at low-temp to ensure the dehumidifier doesn’t ice up.

If you’ve never used a dehumidifier before, these controls will be simple enough to ensure you can just switch on your unit and forget about it – until it’s time to empty the water tank at least!

Underwhelming double filtration technology

I would never recommend you use a dehumidifier to clean the air in the room as an air purifier will always be a better appliance for that specific job. That said, I was happy when I read that the De’Longhi DEX214F came with a double filter system as air filtration technology should keep out particulate matter that might damage the parts inside the unit.

The double filter in the DEX214F is comprised of a dust filter and a replaceable allergen filter for picking up smaller particles.

DeLonghi DEX214F Dust Filter

The dust filter is fine and covers the entire air intake but I wasnโ€™t impressed with the allergen filter.

The problem is that the โ€œallergen filterโ€ is very very small and only protects the air coming from one section of the air intake, so it is basically useless. 

Delonghi dehumidifier filter

Overall this was one of the weakest areas for this particular dehumidifier. I hope that De’Longhi looks at a more effective allergen filter for future models, such as the large filters used in British-made Ebac dehumidifiers.

The De’Longhi DEX214F lowered humidity levels in our test tent within 10 minutes

As I briefly explained earlier in this review, I ran three tests on the De’Longhi DEX214F in my basement to assess its performance in real-life conditions.

The first test was the dehumidification performance test, where I ran the DEX214F inside a Gorilla Grow Shorty Grow tent (3ft x 3ft) placed in the most humid area of my basement.

In the graphic below, you can see how quickly the humidity was reduced after switching on the dehumidifier:

Relative Humidity Test DEX214F 1

It took less than 10 minutes to reduce from 71% to under 30% relative humidity, which is to be expected in a small space but still impressive to see. By the way, I used a Govee Wifi hygrometer to measure the temperature and humidity levels. What I like about this device is that you set it and then easily pull data in one-minute intervals.

In the graph above, you can see how effective the onboard humidity detector is. You will see that the sensor detected rising humidity levels, and once they hit a high level (60%), the DEX214F automatically switched on to full power till humidity levels dropped.

Every time humidity levels exceeded the average, the onboard humidity detector picked up those levels and switched on the unit until the desired humidity was reached.

It’s worth mentioning that this is a test we have designed to test humidifiers in a controlled space (our grow tent). It is a small space, and most people wouldn’t even consider using a dehumidifier inside a tent, but in terms of our testing, I was pleasantly surprised by the dehumidification performance of the DEX214F.

The only downside was remembering to remove the water, as the 1.2L bucket gets filled pretty quickly in very humid conditions, and my basement is ridiculously humid.

Noise levels test results

When running at its top mode, the De’Longhi DEX214F hit a maximum of 40 dB. This is equivalent to a refrigerator humming in the background.

We’ve recorded a video where we take the dehumidifier from mode to mode so you can listen to the associated noise levels with your own ears, as I understand that noise levels are a personal thing.

The cost to run a De’Longhi DEX214F: $206.04 per year

As part of my testing, I used a power meter to see how much power was used when the dehumidifier was on standby mode (not actively removing water) and found that it used 1.5W (left), which is around $2.1 per year, assuming the average utility rate in the U.S. of $0.12/kWh.

DeLonghi DEX214F Electricity Consumption

Once the dehumidifier detects an increase in humidity, it will go into full power mode, and as you can see in the image to the right, it increased to 195.6W, which is $206.04 per year (U.S. average utility rate of $0.12/kWh).

The reality is that most people wonโ€™t need to run their dehumidifier non-stop for 24 hours a day every single day of the year. But by looking at these figures, you can clearly see the financial benefit of an automatic system that reduces usage when the humidity target is reached.

Bottom line

If you are looking for a premium dehumidifier for a small to medium-sized room and you are based in the European region, you can’t wrong with the De’Longhi DEX214F.

Itโ€™s not without its faults, such as the tiny โ€œallergen filterโ€ but these cons are minor when weighed in the context of this unit’s performance. The power of this dehumidifier more than makes up for these minor issues.

DeLonghi DEX214F Living Room

De’Longhi is not a company name I would have connected to powerful dehumidifiers, but now that I have tested one of their units firsthand, I am impressed. I would be interested in future models from this company, and I have high expectations for its long-term usage. I do hope they make these dehumidifiers available in America soon.

Rainbow RainMate review

Rainbow RainMate Side Table

The Rainbow RainMate air purifier was invented as part of a patent developed by Rexair in 1988. That patent expired in 2006, so the market is now full of these โ€œwater air purifiersโ€ that allegedly afilter air through water to remove pollutants.

While the primary market for this invention was a new type of vacuum cleaner, Rexair decided to use this technology on a smaller scale as part of an air cleaner. However, the Rainbow RainMate air purifier is not sold directly to the consumer. Instead, it’s used as part of a home sales presentation where a salesperson would try to sell a $3000-$4000 cleaning vacuum system while gifting or heavily discounting the price of the Rainbow RainMate along the way.

Iโ€™m not a fan of direct selling, as it naturally disadvantages the consumer, who will feel pressured to purchase something with someone in their home. Thankfully, I didnโ€™t have to sit through a presentation for my Rainbow RainMate.

We bought the Rainbow RainMate with our own money and tested it to assess its air cleaning performance, energy efficiency and sound generation. You can read more about our air purifier testing process, but in short, we gather comparable data to help consumers compare and contrast the minefield of air purifiers on the market.

We donโ€™t run ads on our site and are independent, so we are free to say exactly what we think about the air purifier we review. Unlike most sites that review air purifiers, we regularly share devices that fail to live up to the hype or those that should be avoided.

The lowdown on the Rainbow Rainmate

Danny Ashton HouseFresh
โ€œThe first thing that made me wary of this device’s effectiveness was the lack of data about its cleaning power. The manufacturer doesnโ€™t share clean air delivery rate (CADR) figures or third-party tests, which is the first indicator of a potentially bad investment.

The Rainbow RainMate has not associated filter costs, but it failed to complete our particle removal test.

After testing this device, it is my opinion that this is a pretty-looking fragrance diffuser, but it shouldn’t be considered an air purifier.โ€
โ€” Danny Ashton, HouseFresh Founder & Senior Writer

PRICE on amazon PRICE on EBAY

If you donโ€™t want to read my 2000-word review on this air purifier, then you can see my key points below:

What we really like

Itโ€™s not a massive investment. I paid $54 for my device, but there are also plenty of generic versions on Amazon.com for around $40.
Water is a sustainable filter. It doesnโ€™t create any harmful byproducts that you find with ionizers.
The LED lights look pretty good. This is especially true when you turn on this device in the dark.
Good diffuser. It’s a small and fairly easy way to deliver fragrances to your room.

What we think could be better

It doesn’t clean the air. It failed to remove particulate pollutants from the air in our particle removal tests.
It is sold door-to-door. I don’t like that the unit is sold directly via salespeople as it puts the consumer at a disadvantage and pressures them to buy.
It shouldnโ€™t be sold as an air purifier. This is a water-based fragrance diffuser.

HouseFresh rating:โ˜†โ˜†โ˜†โ˜†โ˜† (if we could give it negative stars, we would)

At HouseFresh, we have tested over 105 air purifiers and recently put together our list of the best cheap but great air purifiers. We also have small air purifiers for those who want something that doesn’t take up too much space and would make a great alternative to the Rainbow Rainmate.

Looks more like a coffee machine

The Rainbow RainMate looks more like a coffee maker than a standard air purifier.

Rainbow RainMate Living Room

Itโ€™s small and easy to use, and you can easily keep it on top of furniture. The design is pretty minimalist with a blue bowl for the water and a top you can unscrew to replace the water. On the top, you will also find one button with two modes: one to turn on the RainMate (one line) and another to turn on the LEDs (two lines).

Rainbow RainMate Top

This simple control panel makes the Rainbow RainMate incredibly easy to use.

You just need to switch it on when itโ€™s full of water by pressing the button with one line ( – ), and the RainMate will start pulling air from outside into the main tank, causing the water to start bubbling. If you want to add some color to the experience, you can turn on the LED light by pressing the button with two lines ( = ).

Rainbow RainMate Controls

The main tank needs to be filled with water before you can use your Rainbow RainMate, and this is also easy. Make sure to unplug the device before you unscrew the top cover, using the handle clockwise to reveal the opening of the water bowl.

Rainbow RainMate Open Bowl

As I mentioned earlier on in the review, I think the Rainbow RainMate is a nice air freshener. You can actually add fragrances to the water for aromatizing or deodorizing the air. The manual of the device clearly states that one should only use Rainbow brand fragrances in the RainMate as other oils and liquids could cause damage โ€” I haven’t tested this, so I can’t confirm whether this will be the case.

Before you plug and turn on the RainMate, you need to make sure the top is fully closed and that it doesn’t tilt or move when sitting on top of the water bowl.

Water filtration technology

No need to replace particle or gas filters with the Rainbow RainMate โ€” too good to be true?

Rainbow RainMate Bowl above

Unlike the standard air purifiers we review here at HouseFresh, the Rainbow RainMate uses water as the filter. The water will need changing when running the unit for a long time, but this will not incur additional long-term running costs compared to normal air purifiers with activated carbon and HEPA-like filters.

Rainbow RainMate Front

I have read many academic studies that support the excellent performance of HEPA filtration at removing particle pollutants. I’ve also read papers and studies supporting the performance of activated charcoal at clearing gasses from the air. However, I have never seen any studies supporting the technology used in the Rainbow RainMate or proving the power of water to remove particles and VOCs from the air.

The reality is that no one likes having to purchase new filters every six months, so water-based air filtration sounds like the perfect solution. That said, at this stage (and considering the performance of the Rainbow RainMate and similar units in our tests), I think this just sounds too good to be true.

The Rainbow RainMate was unable to clean the air in our test room

The RainMate took so long that the phone I use to record the particle removal test ran out of battery.

Rainbow RainMate Test

We started our test in the same 728-cubic-feet room where we tested all of our air purifiers, filling up the room with incense smoke at 2:11 p.m.

We switched the Rainbow RainMate on at 2:42 p.m. and then tracked the levels of PM1, PM2.5 and PM10 particles in the air with our air quality sensors from PurpleAir. We also filmed the test so our readers could see how well the device removes particles from the air in real time. 

You can view the video below:

Most particle removal tests are completed within 60 minutes, although some smaller devices can take double the amount of time. For example, the like the Levoit Core Mini took 113 minutes.

In the case of the Rainbow RainMate, the results were even worse.

For starters, at 5:25 p.m. my iPhone ran out of battery, so the test continued without being filmed. This was 163 minutes after 2:42 p.m., which was the time when I switched on the device.

However, the experiment continued until 6:03 p.m. At that time, I made an executive decision to end the test. At that point, the level of PM1 particles was still at 20.14 and any further reductions would just be down to the natural ventilation in the room.

Even after 3 hours and 35 minutes, our test room was still polluted with tiny particles.

Based on the 70+ air purifier performance tests we have completed so far, the Rainbow RainMate sits at the bottom of our leaderboard as it was unable to clean the air in our test room. The only other device we tested that was unable to remove all PM particles was the infamous Sharper Image Ionizer Breeze from 10+ years ago. 

Air cleaning performance, compared

You can see here how the terrible performance of the Rainbow RainMate Water Air Purifier compares to other low-budget units on the market:

We even compared it to devices like the IQair Atem Car, which is designed to work inside a car cabin, and the Rainbow RainMate still trailed far behind them.

The fact that this unit is touted as suitable for asthmatics and allergy sufferers is not true. This device will not be able to remove pollen and dander quickly enough to avoid triggering allergy/asthma symptoms.

Considering that Rainbow RainMate was unable to remove incense smoke pollutants, I know it will be useless against real-world issues such as wildfires or cigarette smoke, both of which create many more pollutants. 

Noise levels, compared

We recorded the noise levels generated by the Rainbow RainMate using a sound monitor from three feet away. While the sound is less intrusive than a standard fan, it still hits 53.3 dB, far from the silence touted in its marketing material.

This is how this compares to other small devices and some of the loudest we’ve tested:

As with all the air purifiers we have reviewed here at HouseFresh, I used an energy meter to measure how much electricity the Rainbow RainMate pulls when running.

Rainbow RainMate ElectricityTest

The Rainbow Rainmate pulled 10.7 watts without the lights running and 10.8 watts with the lights running. 

Electricity consumption with light offElectricity consumption with light on
10.7 watts10.8 watts

2. Filter costs = $0 per year

As this air purifier uses water to filter the air, there are no extra filter costs to consider, as you just change the water every few weeks. 

Bottom line: Is the Rainbow RainMate worth it?

You often hear the phrase, โ€œIt sounds too good to be true,โ€ and for the Rainbow RainMate, this might be the case. 

After testing the Rainbow RainMate, it is my opinion that this is a pretty-looking fragrance diffuser, but it shouldn’t be used as an air purifier โ€” especially not one to be used to help ease asthma and allergy symptoms. Our particle removal test showed the Rainbow Rainmate will not be able to clear the air of pollutants that trigger allergic symptoms.

Some of our YouTube viewers who have the Rainbow RainMate reported they enjoy the relaxing sound of the water twirling around inside the bowl and that they like the mood set by the LED lights. I agree with them that this is a cute water whirilpool thingy, but please don’t get confused to think this is an air purifier.

If you are trying to buy a small air purifier, I would suggest you look at the Winix A230 instead or the even smaller Smart Air QT3. You will have to accept that you will need filter replacements every few months, but in exchange, you will be confident that it is cleaning the air in your home.

Rainbow RainMate Lights

But if you want a water fragrance diffuser like the RainMate, you will be able to find one on eBay and you can also get a generic version on Amazon. I would suggest you don’t accept salespeople in your home as I have read that the RainMate is often offered free or as a โ€œprizeโ€ if you agree to a salesperson visiting your home with the goal of hosting a presentation to sell you a higher-priced vacuum cleaner ($4,000).

Now, I have written quite a few negative reviews of air purifiers over the last few years, but I have never received as many irate emails as I did when my video review of the Rainbow RainMate went live.

Most consumers will just feel a little embarrassed that they bought a sub-par product and will email me to ask for a recommendation that will not break the bank after they have already invested in a bad device. But in the case of the comments and emails i received about the RainMate, I wonder if these are not customers but people using the RainMate as part of their sales pitch for other products.

So I went over to Reddit to dig a little deeper and was shocked at the number of people talking about the Rainbow โ€œFresh Air Machine.โ€  From reading many threads, itโ€™s clear that the RainMate is being used as a hook to get salespeople though the door as part of a high-pressure in-person sale opportunity.

reddit rainbow rainmate

I would have hoped that the invention of the Internet would make this type of in-person sales technique obsolete, but unfortunately, that doesn’t seem to be the case. I hope this review will provide more insights to people who are feeling the pressure to get this product.

If you found it helpful, be sure to share it with your friends and on social media.

We used the Department of Energyโ€™s appliance energy calculator to calculate the yearly electricity costs associated with running the Rainbow RainMate for 24hs a day for 365 days. We ran this calculation utilizing the U.S. average utility rate of $0.12/kWh as of May 31st, 2024.

Smart Air QT3 review

Smart Air QT3 Small Room

Smart Air isnโ€™t one of the big-name air purifier brands yet. But it has been making waves in the industry recently with its low-cost yet powerful air purifiers. 

Born out of a desire to solve the air pollution problem, Smart Airโ€™s founder, Thomas Talhelm, entered the arena with a mission; to create easy-to-use, high-performing air purifiers at a fraction of the price of the top-tier models. 

By strapping a HEPA filter to a fan, Thomas successfully created a simple air purifier that created a buzz online and laid the foundation for Smart Air. Since its inception in 2013, Smart Air has been shipping affordable, no-nonsense air purifiers worldwide and providing free education on air pollution. 

Today, the company has a wide range of air purifiers, including the Smart Air QT3, the popular Sqair Air Purifier and the high-performance Blast MK 11 Air Purifier. The Smart Air QT3 is a compact air purifier designed to provide clean air on the go. 

At HouseFresh, we take pride in our review process, aiming to bring clarity to the world of air purifiers. We purchase every product we review out of our own pockets, allowing us to poke holes and bring to light what manufacturers will not tell you about the product. 

Hereโ€™s how we tested the Smart Air QT3:

  1. In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
  2. We set up our trusted Purpleair Indoor Sensor with the latest Bosch gas sensor to track levels of PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 and VOCs in the air.
    purpleair
  3. We switch the air purifier to its highest speed and measure how long it takes to get our room air quality down to PM1 level to 0.
  4. For portable air purifiers, we repeat this test inside our Tesla Model 3 to see how good the unit is at cleaning the air in a small enclosed space.

In this review, I will walk you through what we found when testing the QT3. But let’s start with a tl;dr for those of you who just can’t sit through a full in-depth review (no judging!)

The lowdown on the Smart Air QT3

Danny Ashton HouseFresh
โ€œThe QT3 is a solid portable air purifier from the team at Smart Air that is not yet perfect but is one of the more capable air purifiers you can use on the go.โ€
โ€” Danny Ashton, HouseFresh Founder & Senior Writer

Smart Air QT3 Car

U.S. PRICE UK PRICE

What we really like

It is portable and lightweight at only 610g
Perfectly safe, ozone-free technology as only uses HEPA technology
It’s a quiet air purifier (as low as 36 dB)
Can make clean air accessible no matter where you go, thanks to the 2,000mAh battery

What we think could be better

No activated carbon to deal with VOCs and odors
It is not yet available on Amazon
Only ideal for small spaces. It is not to be used as a replacement for a full-size air purifier like the Smart Air S or the SA600.

The specs

This model is the only portable that Smart Air makes and has become a significant favorite with travelers looking to reduce the risk of Covid-19. It costs $44 with a CADR of 24 CFM and has a recommended room size of up to 54 ftยฒ.

The QT3 looks great

This portable air purifier features a super-sleek design, as expected from a company like Smart Air. 

Smart Air QT3 Front

The Smart Air QT3 is a lightweight, aesthetically pleasing air purifier ideal for cleaning the air in a small room. It is made from high-grade plastic in fresh white and summer pink finishes. A cable tray at the top lets you keep your USB-C cable.

At the front of the device are fins that you can adjust manually. Unlike other air purifiers weโ€™ve tested, the QT3 has a plastic handle that makes it easier to carry around. 

Smart Air QT3 Top Down

Two versions are available for the Smart Air QT3: The Home Edition, which has no battery and the travel edition we received for this review. It comes with a 2,000mAh battery that lasts four hours, making it ideal for use when driving or on public transport.

Measuring 150 x 145 x 180mm, the QT3 has a small form factor compared to other air purifiers weโ€™ve tested. In comparison, itโ€™s much bigger than the Levoit Core 300 but similar in size to Levoit Core Mini

Below is a photo comparing it with another contender in the portable air purifier space: the Pure Enrichment PureZone Mini. The QT3 is much bigger in comparison, but they both stay true to their portable nature.

Smart Air QT3 VS PureZone Mini

At 1.3 lbs, the QT3 is very portable. While it’s a tad more prominent than the other mobile units available, it’s still very light for an air purifier.

Like other Smart Air units, the QT3 is simple to use with just two buttons.

Smart Air QT3 Controls 3

One is for powering the device, and the other is for adjusting the fan speed. Alongside the buttons are four LED lights, three for indicating the speed and the fourth one for the filter. The filter indicator will light up when the HEPA filter needs a replacement. 

It will not filter unwanted smells

The QT3 comes with a high-density H11 HEPA filter but it doesn’t include activated carbon

Smart Air QT3 Filter change 1

The Smart Air QT3 comes with high-density H11 HEPA filters, which can remove 95% of pollutants, like PM2.5, allergens, pollen, fur and bacteria.

Smart Air QT3 HEPA

The QT3 purifier contains no ionizers and doesnโ€™t emit dangerous chemicals like ozone. However, it lacks an activated carbon filter, so it cannot remove odors and volatile organic compounds (VOCs) from indoor air.

I understand this would likely have to be such a small charcoal filter that it’s unlikely to perform well, but I would love to see it in version two.

Smart Air QT3 HEPA top

In comparison, Levoit Core 300 and Levoit Core Mini are equipped with HEPA and Activated Carbon filters, effectively removing odors, VOCs and particles. However, they both need a plug to operate.

Smart Air QT3 Filter change 2

The other portable unit we like is the Pure Enrichment PureZone Mini. The PureZone Mini has activated charcoal, but itโ€™s so tiny that we didnโ€™t see any difference in odor when we tested it.

Changing the filter in your Smart Air QT3 is not difficult at all. One slight issue was that the filter would often slip if I knocked on the device, so I had to remove and reseat the case. It would be good to see a more secure filter in the next design.

Tip

When you first open the Smart Air QT3, the filter will be in a plastic wrapping, so be sure to remove this before you switch the unit on, or it will not be able to remove particles from your air.

The Smart Air QT3 cleared our Tesla Model 3 in 43 minutes

We conducted two tests on the Smart Air QT3: one inside our Tesla Model 3 and one inside the same 728 cubic ft test room, where we test the air cleaning performance of all our air purifiers.

In both cases, we simulated indoor particle pollution by burning an incense stick and tracking how long it took the QT3 to reduce the levels of PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3 in the air with the help of our trusted PurpleAir sensor.

It took the QT3 just 43 minutes to clear the air inside the cabin of our Tesla Model 3:

When it came to cleaning the air of our 728 cubic ft home lab, the QT3 understandably needed a lot more time:

Air cleaning performance, compared

I was impressed by the performance of the Smart Air QT3 when comparing its air cleaning speed with other portable air purifiers.

Things changed, however, when I compared the performance of the QT3 against non-portable air purifiers. Yes, the results look poor, but this is to be expected as portable air purifiers have a far lower air cleaning power (CADR).

That said, the QT3 performed better than its small portable competitors. Just to give you an idea, it took the Pure Enrichment PureZone Mini 5 hours and 39 minutes to clean the air in our test room – that’s one whole hour longer than the QT3.

Noise levels test results

Best Quiet Air Purifiers QT3

The Smart Air QT3 produced 40 dB at the highest fan speed, ideal for home or office use. The unit can go as low as 36.3 dB at the lowest speed, putting it on par with the best ultra-quiet air purifiers weโ€™ve tested.

As you can hear from the video, the noise generated by the QT3 is very quiet:

The cost to run a Smart Air QT3: $39.72 per year

1. Electricity costs = $13.73 per year

Many consumers think about the initial cost of an air purifier but often forget to think about its costs. The Smart Air QT3 isnโ€™t a cleaner that will cost a lot in bills as itโ€™s a small unit with a low power draw of only 9 watts at full power.

While the electricity costs associated with a unit like the Core Mini are a little cheaper ($6.31 per year), the QT3 will cost way less in terms of power consumption than a standard home air purifier like the Levoit Core 300, which costs $37.84 annually.

2. Filter costs = $25.99 per year

As HEPA works by trapping pollutants, these filters become full of particles and eventually restrict airflow to reduce performance. Smart Air has manufactured filters that cost less and last longer. The Smart AIR QT3 has filters available for just $25.99.

In comparison, filters for Core Mini will set you back $49.98, while Pure Enrichment Pure Zone Mini is slightly cheaper at only $20 for one set of filters.

  • LIFE SPAN: Each filter has an 800 hour life span
  • HIGH-QUALITY: Our high-quality HEPA filter pairs with the Smart Air QT3 Portable Air Purifier and Fan

Bottom line

The QT3 is a solid portable air purifier that cleaned the air in our Tesla Model 3 in under an hour

The Smart Air QT3 is not a great air purifier when compared to those you can plug in, as it can only clean a tiny area. It had issues cleaning in our small test room, but it did remove particles from the air when left for long enough.

Its stand-out feature is the ability to be used for travel with its battery, so itโ€™s one of the top portable air purifiers on the market.

Smart Air QT3 Kitchen

Filter prices are fair, as is the cost of the unit. If you have concerns with flying, the Smart Air QT3 is a great option. If you’re looking for an air purifier for your car or an RV, then you should also look at the IQAir Atem.

The QT3 is an air purifier designed explicitly for one type of job, so it is not the most versatile of units.

But you can rest assured that if portability is at the core of what you’re looking for, then the QT3 is one of the best options on the market.

We calculated yearly costs associated with running the Smart Air QT3 24 hours a day, 365 days per year utilizing the latest average energy prices as reported by the Bureau of Labor Statistics of $0.174/kWh as of May 2024.

QP Pro (Qingping CGS1) Review

Qingping Pro Close Up

Yes, itโ€™s probably the strangest brand name youโ€™ve ever seen, but Qingping has been busy making excellent high-end quality sensors with attractive price tags. 

Earlier this year, Smart Air reached out to us, and we got to test and review the smaller Qingping Lite. Its high-end sensor and screen impressed us, costing less than $100. Itโ€™s essentially a cheap air quality monitor that is as good as premium models that cost $250+ 

The Qingping Pro is a little more expensive at $139.99 but can track VOCs and includes a more prominent color screen. It also provides app support with the ability to download your data for analysis. 

TL;DR The Lowdown on the QP Pro

danny

โ€œAn improvement over the QP Lite with the same sensor accuracy and with the additional support for VOCs. It would still be good to have more particle sizes such as PM10 that is included with  the QP Lite, but for the price, this is still one of the best budget air quality monitors on the market.โ€ โ€” Danny Ashton, Founder & Senior Writer


Qingping Pro Living Room Close Up

If you donโ€™t want to read my full review, these are the key things you need to know about the QP Pro air quality monitor. 

What We Really Like:

๐Ÿ‘ The ability to track VOC and PM2.5 accurately without spending more than $150
๐Ÿ‘ The color screen shows PM2.5, temp, tVOC, CO2 and humidifier at one time
๐Ÿ‘ Battery mode allows you to use the sensor without having access to power
๐Ÿ‘ You can easily pull data from the device using the QingPing+ app
๐Ÿ‘ Size is perfect for use on a desk 
๐Ÿ‘ Screen design allows you to understand your current air quality quickly

What We Think Could Be Better:

๐Ÿ‘Ž Lack of PM10 and PM1 particle sensors which would be good to have in future versions
๐Ÿ‘Ž VOC sensor only shows all VOCs and is not able to provide insight on specific problematic VOCs like formaldehyde

The Specifications

Budget air quality monitor with the ability to track VOCs

Like the QP Lite, this is a cheap monitor, but it doesnโ€™t use cheap sensors. It uses the Sensor S8 for PM2.5, an SGP30 for VOC and the same temperature and humidifier sensors used in Teslas [Sensirion].

Perfect Desk Screen

As you can see, itโ€™s a good-looking device.

Qingping Pro Fireplace

The QP Pro has an attractive screen that shows all the information in an intuitive way, allowing you to keep all the different air quality readings in one place.

Qingping Pro Side

Looking at the unit from the side and the back, you can clearly see that itโ€™s bigger than the QP Lite:

Qingping Pro Back

In comparison, the QP Lite is better for travel โ€” I could see the screen getting damaged if you threw the QP Pro in your bag. Whereas the QP Lite is designed to be carried around.

Qingping lite Living Room

Simple System

While you use the top bar to change menus with the QP Lite, you just use the screen with the QP Pro. Itโ€™s similar to a smartphone, so there is no learning curve to use it. 

Qingping Pro Close Up

One significant benefit of the QP Pro over the Lite is having one screen that shows everything. With the QP Lite, you keep moving screens to see different sensor readings.

But that doesnโ€™t mean that the QP Pro doesnโ€™t allow you to go deeperโ€ฆ You will also be able to swipe the screen to move across different air quality factors.

You will have a dedicated screen for CO2 measurements:

Qingping Pro CO2

Another screen where to track TVOC (Total Volatile Organic Compounds) levels over time:

Qingping Pro tVOC History

AND a separate screen for PM2.5 particulate levels in the air:

Qingping Pro PM2.5

I had no issues connecting the Qingping+ app to the QP Pro; it connected to my 5GHZ WIFI with no issues. The air quality monitor will save the latest data on PM2.5, CO2, VOC and temperature and humidifier, allowing you to export this data to see changes over time.

Qingping QP Pro App 1

Like the QP Lite, data is provided every 15 minutes, which is fine for looking at historical data. However, I prefer having data every three minutes, which is the case with the Purpleair Indoor Sensor ($200 with no portable mode).

Qingping QP Pro App 2

Export Your Air Quality Data

I exported the data from my QP pro and then used Flourish to create this simple line graph:

If you use specific smart appliances like those from Xiaomi, you can enable your devices to switch on based on data from your air quality sensor. 

QP has also promised that a new update will allow for your data to be used with Google and Alexa, although this hasnโ€™t been rolled out yet, so I havenโ€™t had a chance to test it. 


Bottom Line: Good Price, High-End Sensors Desk Air Quality Monitor

The QP Pro can accurately measure VOCs, PM2.5, CO2, temperature and humidity โ€” features usually only available for $250+. 

Qingping Pro Living Room Close Up

Itโ€™s always a challenge to understand VOCs, as sensors can only measure all VOCs, including those that are not harmful. I would have preferred to see PM10 and PM1 rather than VOC, so I would still recommend the QP Lite over the QP Pro, as itโ€™s cheaper and gives more insight into particulate pollution. 

If you are a big fan of having a clear screen to see your air quality on your desk, then the QP Pro might be something to look at. 

AROEVE MK01 review

AROEVEMK01

AROEVE doesn’t make it easy to find out much about the company: their website is empty of information and there arenโ€™t many details on their Amazon profile page. When I tried to find out more information about the https://aroeve.com/ website through a WHOIS query that pulls out domain registration data, I learned that their site is hosted on Alibaba and the domain is registered in China. So, we assume that this is a Chinese company that sells primarily on Amazon.com.

The MK01 is the most popular air purifier sold by AROEVE, but they also have the MK02 ($55) and MK04 ($99) which are designed for larger rooms. The AROEVE MK01 is targeted towards smaller rooms (up to 215 sq. ft.) and includes an aroma pad. 

If you do a quick search on YouTube, you will see plenty of reviews for the MK01:

AROEVE MK01 YouTube Reviews

However, they are all very positive, making me think that many of these โ€œreviewersโ€ were provided this unit for free in return for a review.

Here at HouseFresh, we never accept free products in exchange for reviews, as we want to stay as unbiased as possible to provide our readers with the truth (positive or negative), so you can find the right air purifier for you. We ran a number of performance tests on the AROEVE MK01 before I wrote this review.

PRICE on amazon PRICE on EBAY

If you just want to know whether this air purifier is good or not then I can save you time and tell you to avoid this purifier and go for something else like the Taotronics AP-033.

What we really like

Itโ€™s a small unit, making it easy to put on a desk or in a location where a larger air purifier would be too big
The lights are cool, although I donโ€™t think they help with the air cleaning!

What we think could be better

AROEVE doesnโ€™t share the CADR score for this air purifier and thatโ€™s likely because itโ€™s very poor 
It took 2 hours and 43 minutes to get our home lab down to a breathable level 
It failed to remove all pollutants in 5 hours, something we usually only see with very small air purifiers
Filters are $19.99, which seems cheap but considering the lack of cleaning power is a total waste of money

Small and cheap with simple controls

From a design point of view, the AROEVE looks cheap but is certainly not the worst air purifier I have seen. The size is great and would be perfect if it was able to also achieve great cleaning power. 

AROEVE MK01 Close Up

The MK01 has simple controls with no app or auto mode. You can choose a timer of 6, 12, and 24 hours.

AROEVE MK01 Controls

When you compare it with the Levoit Core 300, the MK01 is much smaller. However, this means that the unit will find it hard to clean as much air in comparison, as mechanical filters such as HEPA require a large surface area and a powerful fan to effectively clean the air in a room.

AROEVE MK01 Comparison

Pointless medical grade filters

The MK01 uses HEPA H13 which is the medical grade of HEPA – a strange choice considering that the unit is so small. Higher grade HEPA like H13 need more airflow to work efficiently, so many manufacturers will often use lower grade filters.

AROEVE MK01 HEPA

These filters can move more air in a compact space, meaning a quicker clean. I assume that AROEVE uses H13 as a marketing tactic, as they make a big show of it on their Amazon page.

In addition to HEPA filter, the AROEVE MK01 also comes with a fine pre-filter and an activated carbon filter:

AROEVE MK01 Carbon Filter

Tip

Be sure to remove the filter from the plastic bag, as the unit will not work unless air can flow freely into the filter.

Watch our video if you are wondering how easy it will be to replace the filters in an AROEVE MK01:

The AROEVE MK01 cleared our test room in 2 hours and 43 minutes

When writing this review, I was surprised to see all the reviews for this unit that stated it cleaned their air well, although not one had tested this for real. 

At HouseFresh, we test all our units to confirm manufacturer data is correct. This allows us to uncover the performance of units without lab data, such as the AROEVE MK01. 

We conduct our tests in the same 728 cubic ft home office, which allows us to compare the performance across all the air purifiers weโ€™ve tested. The test has three parts:

  1. We introduce particulate pollutants into the room by using an incense stick
  2. We track the time it takes for the air purifier to remove all pollutants using an indoor sensor from Purpleair, that provides us with data on PM1.0ug/m3, PM2.5ug/m3, and PM10.0ug/m3
  3. Throughout it all, we gather energy consumption data with the help of a power meter and noise levels in decibels.

When it comes to the performance of the AROEVE MK01, we encountered the same issue we had with the Molekule Air Mini: the unit was unable to get the number of pollutants down to zero.

That being said, the MK01 managed to get air down to a breathable level (per World Health Organization guidelines) but had problems getting this level down further. This makes me think that this air purifier was too small for even our small office.

You can see the results of our air cleaning performance test in the interactive chart below:

To achieve the WHO breathable level it took 163 minutes (or 2 hours and 43 minutes), which is very poor compared to other units weโ€™ve tested – including the ULTTY CR021, a fan and air purifier unit that took 131 minutes to clean the air in the room.

Air cleaning test results

Overall, itโ€™s safe to say that this is one of the worst air purifiers we have tested here at HouseFresh.

Noise levels test results

At its lowest speed, the MK01 generated 39.8 dB of sound but you would not use this speed in reality as it is truly useless. The noise level doesn’t go up that much at the highest speed, reaching 48.1 dB. However, this is less than 1 dB higher than the Levoit Core 200S at top speed.

Have a listen for yourself:

The cost to run an AROEVE MK01: $44.85 per year

1. Electricity costs = $24.86 per year

With electricity costs expected to increase, this is a figure worth knowing before investing in an air purifier – a gadget that you will likely use 24/7, especially if you have issues with outdoor pollution.

Based on the U.S. Bureau of Labour Statistics average energy prices, this unit will cost you $24.86 a year to run constantly at top speed if you live in America.

2. Filter costs = $19.99 per year

AROEVE MK01 Filter unit

An area that customers new to air purifiers often forget about is that HEPA filters will need to be replaced every 6 months for smaller units. The filters from AROEVE are $19.99, and while this seems cheap when you compare it with its cleaning power, itโ€™s far too high to recommend to most people.

Bottom line: Should you get an AROEVE MK01?

On paper, the AROEVE MK01 seems perfect, as it is priced cheaply at $59.99 and has 4.5 stars on Amazon.

The reality becomes apparent when we use Fakespot and see that the MK01โ€™s adjusted score is 3 stars, due to the evidence of review manipulation.

MK01 Fakespot Amazon Reviews

Personally, I would recommend paying $20 extra and going for the Taotronics AP-033, which operates much better across all areas and has been proven to clean the air effectively in rooms larger than the recommended size for the MK01.

Blueair Blue Pure 311 Auto review

Blueair Blue 311 Kids Bedroom

Blueair is well known in the world of air purifiers as theyโ€™ve been selling them since 1996. Originally from Sweden, the company became part of the multinational Unilever in 2006. They create many different air purifier ranges, and Blue Pure is their budget performance range. This range doesnโ€™t have the features and extras you get in their premium ranges. 

The cheapest Blue Pure air purifier (Blue Pure 411+) is available for just $119.99, and the 311 Auto we are reviewing here costs $229.99.

As I always like to clarify, we donโ€™t accept free units in exchange for reviews. We buy all the air purifiers with our money, so we can share in detail how they perform with no biases. The core part of our review process is our performance test. This is where we put all units through the same test inside the same space so that we can compare their performance like for like.

How we test air purifiers

Read our full testing methodology.

This review will walk you through the findings of our performance test. Whenever possible, I will compare this unit with other similarly priced air purifiers on the market so you can decide which of them is better for your individual needs. I will also share my impressions when using this air purifier regarding the design, portability, user experience of its control panel, and more.

Okay, let’s get to it.

The lowdown on the Blueair Blue Pure 311 Auto

Danny Ashton HouseFresh
โ€œIf you donโ€™t want to use a bigger air purifier and have a room around 400 sqft, this is the perfect unit. I still think the Blue Pure 211+ is a better deal with an extra 100 CFM CADR for $100, but if this is too big/pricey, then make sure you check out the Blue Pure 311i Max as this has the same cleaning performance, price and also comes with smart app support.โ€
โ€” Danny Ashton, HouseFresh Founder & Senior Writer
Blueair Blue 311 Living Room

What we really like

Took 21 minutes to clean our test room compared with 43 minutes for the smaller Blue Pure 411+
53 dB at max fan speed was less than the Blue Pure 211+, which hit 56 dB
34.5 watts at full speed, which makes it one of the most efficient at this level of performance
Ability to customize the design with different choices of pre-filters
HEPASilent brings high CADR without the usual size and cost you see with pure HEPA and activated charcoal

What we think could be better

You need to pay more to get the auto mode which feels like it should be standard
Smart features are only available on the latest generation โ€” I wish this were rolled out to all models 
The ionizer function cannot be disabled

The specifications

250 CFM CADR for less than $240 is a strong proposition considering you would need $500+ for a similar performance from other air purifiers.

Customizable design and simple control panel

The Blue Pure range of air purifiers all have the same simple look, with one button to control everything. You also can change the pre-filter to fit your interior design scheme.

Blueair Blue 311 Top

Simple is the name of the game with the Blueair Blue Pure 311 Auto. The control panel canโ€™t get much simpler with a device like an air purifier. One-click switches into auto-mode, and you can then leave the unit to change speed automatically as it senses new pollutants.

Blueair Blue 311 Info

Pressing the button again, you can adjust the speed with three options. Press the same button again and it switches off. Itโ€™s that simple! 

On the front of the unit is a small LED that acts as an air quality indicator and a filter replacement warning light. When in auto mode, this light will report the air quality in your room with three different colors. Your air quality is measured in real-time using the sensors on the back of the unit.

Blueair Blue 311 Air Quality Sensor


A cool feature that Blueair has used previously is to customize your unit using the different color pre-filters. Keep the gray one it comes with, or spice it up a little by swapping it out for Arctic Trail, Night Waves, Archipelago Sand, Winter Reed or Aurora Light:

Blueair Blue Pure 311 Auto Fabric Options

The 311 Auto is the middle-sized unit in Blueairโ€™s Blue Pure range, between the smallest 411+ and the second largest 211+.

When comparing the Blue Pure 311 Auto (right) with the 411+ (left), you can see the difference in size is not as stark. The fact that the 311 Auto manages to drive 250 CFM with such a small unit is impressive:

Blueair Blue 411 VS 311 Auto Comparison

The size difference is more noticeable when comparing the 311 Auto (right) against the larger 211+ (left). The 211+ weighs 12.5 lbs (5.67 kg), nearly double the 311 Auto (6.8 lbs or 3.08 kg).

Blueair Blue 311 VS 211 Comparison

The Blueair Blue Pure 311 Auto is a good-looking air purifier that will fit small to medium-sized rooms without taking up too much space.

HEPASilent filtration technology for rooms sized 400 sq. ft.

As with all the Blueair range, the Blue Pure 311 Auto has a filter powered by HEPASilent technology, combining electrostatic and mechanical filtration technologies.

Blueair Blue 311 Filter Tag

Wondering how HEPASilent technology works? The fan draws air into the Blueair Blue Pure 311 Auto, where airborne particles receive an electrical charge causing them to adhere to the filters.

Larger particles get stuck in the washable pre-filter before the air moves through the HEPA filter, which removes pollen, dust, pet dander, viruses and bacteria:

Blueair Blue 311 HEPA Filter

From that point, the air moves through the activated carbon layer, which removes odors from pets, cooking and smoking.

Blueair Blue 311 Activated Carbon Filter

The HEPA filter will need replacing around every six months (the filter replacement indicator will let you know when), but donโ€™t worry; itโ€™s super easy to do so. 

Follow these step-by-step instructions:

  1. Unplug your 311 from the outlet
  2. Twist the top of the unit (the white bit) until you feel it unattached from the body, and remove
  3. Peel the velcro from the pre-filter and pull it from the HEPA filter
  4. Pull the pre-filter over the new HEPA filter and reattach the top
Tip

This is the perfect time to wash the pre-filter and clean the rest of the air purifier so it works to its maximum efficiency.

As with the 411 and 211 range, the Blueair Blue Pure 311 Auto brings excellent performance for $ spent, dB created and energy usage. The HEPASilent matches its expectations, and this unit has the best air cleaning performance value for rooms sized 400 sq. ft.

Be aware that when receiving a new unit or buying a replacement, the filters will be in a sealed bag and must be removed before they can be used.

The Blue Pure 311 Auto cleared our test room in 21 minutes

The main job of an air purifier is to remove tiny particles from the air, as we know how damaging they can be. We test every unit we review with the same methodology to determine its effectiveness in this area. 

We burn an incense stick in our 705 cubic ft test room, and using air quality sensors, we track how long it takes a specific air purifier to remove PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3. 

We track this data and compare the performance to all the other units we have tested.

</

Air cleaning performance test results

The Blueair Blue Pure 311 Auto took 21 minutes to achieve a level of 0 PM1. This is 22 minutes better than the smaller 411+ and only three minutes less than the larger and higher-priced 211+.

The 311 Auto provides excellent cleaning performance on a budget. It took the Alen 75i three more minutes to clean our test room. The Dyson HP04 combo unit, which costs over $700, took 63 more minutes to remove all the pollutants. 

Noise levels test results

The Blue Pure range is hard to beat for pure power to sound. We had high hopes for the HEPASilent technology and were impressed with the maximum level of 53 dB, which is in range with much smaller units with less performance like the Levoit Core 300, which took 40 minutes to clean and had a maximum sound level of 50dB. 

Cost to run the Blue Pure 311 Auto: $116.77 per year

1. Electricity costs = $36.79 per year

At its maximum fan speed, the Blueair Blue Pure 311 Auto only recorded 34.5 watts, the same as the highest-power LED bulbs on the market. Compared to competitors, it pulls much less power; the Levoit Core 300, for example, recorded 45 watts for less air-cleaning power. 

2. Filter costs = $79.98 per year

The filter costs are fair for this level of air cleaning performance and the all-in-one filter only needs replacing twice in 12 months. Some generic filters are available, which brings the cost per year down to $43.99 for two filters, one of the cheapest we have seen for this level of air cleaning.

Bottom line

The Blueair Blue Pure 311 Auto gives you a great performance ratio to sound, price and energy usage. This is the perfect air purifier for those who love the Blueair Blue Pure range and have rooms that are too big for a Blueair 411+ but not big enough to warrant a Blueair 211+.

Blueair Blue 311 Kids Bedroom

If you want an air purifier that with a customizable design that is lightweight and offers solid air cleaning performance for a medium-sized room (like a living room or a bedroom), then the Blueair Blue Pure 311 Auto is a good option to keep your room free of pollutants without noise disturbance or bulky aesthetics.

Blueair Blue Pure 411+ review

Blueair Blue Pure 411 Living Room

Originally from Sweden, Blueair has been in the air purifier industry since 1996. The company was bought by the mega-corporation Unilever in 2016.

Their Blue Pure series of air purifiers offer simple units that do an excellent job of cleaning the air. Their trademarked HEPAsilentโ„ข process combines a mechanical HEPA with an electrostatic charge to clean more air for less power, lower price and less noise. 

We already found the original OK to be a solid performer, and the Blue Pure 211+ is an easy purifier to recommend for those looking to clean larger spaces. 

The Blueair Blue Pure 411+ is the upgraded version that hopes to build on the success of the Blue Pure 411 with higher air cleaning power for less energy usage.

Weโ€™re here to tell you if it meets those high expectations.

My review will cover all our findings from the performance test outlined above. If you have any questions about this unit by the time you reach the end, please email me as I have tons of data.

The lowdown on the Blueair Blue Pure 411+

danny

โ€œA clear upgrade on the decent Blue Pure 411, the Blueair Blue Pure 411+ is an easy budget air purifier for those looking to clean a small space like a bedroom and who donโ€™t want something that will create a lot of noise.โ€

โ€” Danny Ashton, Founder & Senior Writer

Blueair Blue Pure 411 Kitchen

What we really like

Great cleaning performance to price โ€” cleaned our test room in 43 minutes for less than $140.
Max sound is one of the lowest we have tested at 52.3 dB.
Has a higher cleaning power but uses less energy than the 411.
Improved Pollen CADR over the older 411 with 131 CFM VS. 120 CFM.
Small footprint and easy to live with thanks to the alternative color pre-filters.

What we think could be better

Not pelleted activated carbon, so expect not to last as long for removing odors.
Not auto-mode unless you pay for the upgrade.
HEPASilent is non-optional.

Swedish design that is easy to live with

Blueair Blue Pure 411 Unit

I have been a big fan of Blue Air designs for a while. You can customize the overall look by changing the filter to a different color, but itโ€™s still a good-looking machine, even without the pre-filter.

Blueair Blue Pure 411 No Pre Filter

Simplicity is the name of the game with Blueair purifiers and the 411+ is no different. It has no fancy features like timers and auto-mode with app support, although upgraded models do offer these features for a higher price. 

Blueair Blue Pure 411 Top

I particularly liked the magnetic cord straightener as itโ€™s a convenient way to ensure the cable remains tidy and in place.

Blueair Blue Pure 411 Magnetic Cord

One of my favorite things about the Blueair Blue Pure 411+ is how compact it is compared to other units. Just to give you an idea of size, check out the photo below, where you can see how small it is compared to the Blue Pure 211+ (left) and the Blue Pure 311 Auto (right):

Comparison Photo Blueair Blue Pure 211 VS 411 VS 311

The Blue Pure range allows you to change the pre-filter to match your interior design, which feels like a nice Swedish touch.

Uniquetrademarked filter system 

Blueair combines HEPA, activated charcoal and electrostatic charge to create a combination filter that can achieve 120 CFM on less than 10 watts of electricity.

Blueair Blue Pure 411 Genuine Filter

Comparing cleaning performance and energy usage, itโ€™s clear that the HEPASilent filter fulfills its promise of cleaning the air quietly.

Blueair Blue Pure 411 HEPA Filter

A slight minor issue: the filter of the Blue Pure 411+ includes activated charcoal as an impregnated fabric โ€” they perform worse in general for VOC and gas removal than the pellets you see in some brands of air purifiers like the Alen BreatheSmart 45i and Levoit Core 300.

Blueair Blue Pure 411 Carbon Filter

As with all HEPA filters, they need replacing periodically when the fibers become complete with trapped particles. You wonโ€™t have to mark it on your calendar though; the 411+ will tell you when itโ€™s time with a glowing red light.

When the time comes, follow these simple steps:

  1. Unplug your 411+ and turn it upside down
  2. Twist the cap off to reveal the filter inside
  3. Use the tabs to pull the filter out of the unit
  4. Insert the new filter, replace the cap and plug your 411+ in
๐Ÿ’ก Pro Tip: When youโ€™re ready to replace the filter, this is the perfect opportunity to maintain your air purifier, like giving it a good clean inside and out.

Like many air purifiers, the Blueair 411+ will come with filters in a plastic bag, so be sure to remove them before you switch the unit on for the first time.

The Blueair 411+ cleared our test room in 43 minutes

We think itโ€™s super important to get a clear idea of how well an air purifier will do its primary job of removing particles from your home. 

We simulate pollution by burning an incense stick in our 728 cubic ft test room and track how quickly an air purifier can remove PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3 using the PurpleAir Indoor sensor.

Air cleaning performance test results

It took the Blue Air Pure 411+ 43 minutes to bring particulate pollutants down to zero in our test room. This compares favorably with its older brother, the Blueair 411, which did it in 68 minutes with similar power usage and price.

It compares very well to the Dyson PH03, a humidifier and air purifier combo that costs over $700 but needed 72 minutes to clean the same room. 

Noise levels test results

The stand-out feature of the Blueair 411+ is its maximum sound levels of 52.3 dB, much lower than many of the air purifiers we test when running at their top speed.

Best Quiet Air Purifiers 411

The Levoit Core 300 creates 50 dB, and the smarter Mila air purifier goes up to 59dB at its highest speed. The HEPASilent technology lives up to its name of cleaning the air without bringing sound pollution to your home. 

The cost to run a 411+: $34.69 per year

1. Electricity costs = $11.59

With maximum energy usage of 7.65 watts, the Blueair 411+ sips electricity at a meager rate. It compares well with the Levoit Core 300, which pulls 35.5 watts at maximum and even when compared to the lower cleaning performance of the Core 200S, which draws 28.4 watts. 

Blueair has managed to find a way to turn less than 10 watts into the ability to clean our room in 43 minutes. 

2. Filter costs = $23

Mechanical filters like HEPA and activated charcoal have a limited life as they become impregnated with particles from the air, restricting airflow and eventually reducing performance. 

Most small air purifiers need filter replacements every six months and the 411+ is the same. Genuine filters are a little cheaper than competitors at $23 compared to $39.99 for Levoit Core 300 and if you donโ€™t mind going for generic filters, you can find them for $10 per filter. 

Blueair Blue Pure 411+ Genuine Replacement Filter, Particle and Activated Carbon
  • Genuine Blueair replacement filter designed for Blue Pure 411 Auto, 411, and 411+
  • Particle + activated carbon filtration helps reduce allergens, dust, and odors
  • Easy to replace for maintaining cleaner indoor air and purifier performance

Bottom line

A great upgrade to the previous Blueair Blue Pure 411, the 411+ has improved cleaning power while maintaining low filters and energy usage costs. The primary benefit of this air purifier over others is the lower level of sound generation. 

Blueair Blue Pure 411 Entertainment Room

Pure Enrichment PureZone Mini review

Pure Enrichment PureZone Mini Car

The PureZone air purifier is made by Pure Enrichment, a brand from A Bear Down Brands, LLC, based in California. The company produces various home air quality products, from humidifiers to heat therapy. According to Linkedin, they were founded in 2010 and currently have 55 people working for them. 

They make products with a budget in mind, with many lower-priced products that are big sellers on Amazon. PureZone is their design for a portable air purifier and they also sell several standard air purifiers.

The lowdown on the Pure Enrichment PureZone Mini

danny

“The PureZone Mini is an affordable and portable air purifier โ€” great for traveling or for your car, but not a good option for using in your home.”

โ€” Danny Ashton, HouseFresh Founder & Senior Writer

Pure Enrichment PureZone Mini Bathroom

If you donโ€™t want to read my extensive review, here are my key points about the PureZone Mini air purifier:

What we really like

Portable design both in weight and size โ€” super easy to throw in a bag or take on the plane.
Simple to use with one button that does everything.
No ionizer or ion-generating technology that can make air quality worse.
USB-C charging with the ability to charge the battery quickly.
Battery lasts a decent amount of time with 12 hours on low, or 2.5 hours on the highest speed.

What we think could be better

Air cleaning performance is not enough for even the smallest rooms in your house.
Filter costs soon add up and could become a high cost if you use the unit often.
Activated charcoal is used in such small amounts itโ€™s not useful.

You Get What You Pay For

At less than $50 this is one the cheapest portable air purifiers on the market. But its air cleaning power wonโ€™t blow you away, with a CADR score of only 10 CFM.

Itโ€™s tiny!

I love how small the PureZone Mini is. It weighs just under 0.6 lbs, so it is also light enough to use for traveling. 

Pure Enrichment PureZone Mini Front and Back

The size of the PureZone Mini guarantees portability, especially considering the handle at the top of the unit. However, I think there are improvements to be made.

Pure Enrichment PureZone Mini Portable Air Purifier

โš ๏ธ Unfortunately, the handle came off a few times, leading to the unit falling to the floor. Luckily, the air purifier didnโ€™t suffer any damage and I could put the handle in place again.

You will be able to access the filters when turning the air purifier upside down.

Pure Enrichment PureZone Mini Top and Bottom

In terms of comparing the PureZone Mini with other similar portable air purifiers, the number one option would be the Smart Air QT3. Both these units are portable and have similar performance and specifications. In terms of design, the PureZone Mini is much smaller.

Smart Air QT3 VS PureZone Mini

Personally, I like the look of the QT3 but thatโ€™s my preference, for sure. I can see why other people would prefer the PureZone Mini – especially if the idea is to have the unit in their car, as it fits the cupholder like a glove.

Pure Enrichment PureZone Mini Car

Simple 3-speed control

The PureZone Mini portable air purifier is very simple, with just one button that switches it on and three selectable speed modes. 

Pure Enrichment PureZone Mini Controls

I suggest keeping it at the highest speed to clean the air effectively as this is a very small unit. You need to assess if youโ€™re comfortable with the noise level output at that speed, though! Keep reading to learn more about noise levels.

I read about some people hanging the Pure Enrichment Pure Zone around their necks. While I am not sure how effective this would be, it would be straightforward to do, considering how light and small this unit is.

Letโ€™s talk filters: True HEPA with activated charcoal

The PureZone Mini comes with a solid HEPA filter and a small amount of activated carbon. Itโ€™s not bad for filtering the air from particle pollution but it would be useless against VOCs.

Pure Enrichment PureZone Mini HEPA filter

The filters are defined as True HEPA โ€” similar to the H11 and H12 filters that will stop 99.97% of particles smaller than 0.3 microns. It makes sense they would choose to use a lower grade HEPA than the medical grade H13, as this would reduce airflow too much for such a small fan. 

Pure Enrichment PureZone Mini TrueHEPA Filter

There is also meant to be activated charcoal in the pre-filter, but it looks like a minimal amount and I doubt it would do much for odors. I bet it is just included to make it look good in marketing. You need significant amounts of carbon for it to be effective, and in such small amounts, this air purifier is nearly useless for gases and VOCs. 

PureZone Mini HEPA With Activated Charcoal

I liked exploring the interior of the PureZone Mini. Upon inspecting the fan, I would say it reminds me of those small fans used to cool computers. 

Replacing the filter is as straightforward as you could probably imagine. Turn the unit upside down, open the cover and extract the filter:

โš ๏ธ When you first open the Pure Enrichment PureZone Mini, remove the filter from the bag; otherwise, it will do nothing to remove pollutants in your air. 

The PureZone Mini cleared our test room in 5 hours and 39 minutes

No one wants to read an air purifier review that just looks at the design and aesthetics; we want to know how well the unit removes pollutants from your home air. 

As with all the air purifier reviews we conduct here at HouseFresh, we tested the PureZone Mini in our testing room of 728 cubic ft and tracked the removal of incense smoke using our indoor purple air sensor. 

The PurpleAir indoor sensor lets us see how quickly PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 particles are removed from the air. We test all our air purifiers in the same space, allowing us to compare performance across different devices. 

The PureZone Mini is a portable air purifier, so we had problems removing all the pollutants from our test room. 

In 5 hours and 39 minutes, it made the room breathable. Considering the small size of this air purifier, it makes sense that it would not be able to clean the air as it is designed for much smaller rooms. 

Air cleaning performance test results

It didn’t compare favorably with the Smart Air QT3, another portable design that took 267 minutes (roughly one hour less) to achieve a similar level of โ€œclean air.โ€ 

When compared to a non-portable unit like the Levoit Core 300, which managed to clear all pollutants in 40 minutes, you can see the potential downsides of portable air purifiers for use in the home.

Noise levels test results

We also tested noise levels emitted from the PureZone Mini with the help of our sound level monitor. Check out the chart below to find out how sound levels compare to other units:

Of course, noise levels can be a subjective thing as something you find noisy might be totally acceptable to me. Thatโ€™s why I recorded a video so you can hear the sound:

The cost to run a PureZone Mini: $31.42 per year

1. Electricity costs = $11.44

As this is a portable device, the electricity costs will be minimal and related to how much you use it. I was pleased to see a USB-C charging port, as we have many chargers in the house.

Pure Enrichment PureZone Mini Charging point

2. Filter costs = $19.98

$9.99 might seem cheap for a filter replacement, but considering how little air it can clean, the costs could soon start to add up if you use it regularly. In the long term, you would be better off with a large air purifier that would cost far less in filter replacements for any serious issues requiring long-term usage.

We saw that you could purchase generic versions of the filter, bringing costs down to $4.25 if you buy four.

Bottom line 

There are not many portable air purifiers on the market, and this is one of the better ones we have seen. It comes with all the downsides of portable air purifier designs, with a low level of air cleaning performance when used in most rooms in the house, but it could be helpful for travel during flights or driving. 

Pure Enrichment PureZone Mini Bathroom

I like the ability to be able to remove pollutants while I am driving, and for now, this is the primary use I would recommend. If that’s the type of air purification you’re looking for, you should also look at the Smart Air QT3.

Just be aware that you will be disappointed if you plan to use the Pure Enrichment PureZone Mini to replace a standard non-portable air purifier, such as the Levoit Core 300 or the Taotronics AP003.

Austin Air HealthMate review

Austin Healthmate Hallway

Richard Taylorโ€™s wife, Joyce, suffered from respiratory distress syndrome. He noticed that she only had relief when in a clean hospital room. So in 1990, he designed an air purifier that used True Medical HEPA and activated carbon to clean the air inside his home. Within a week of using the first device, Joyce could sleep undisturbed for the first time in years. That was the start of Austin Air.

Now, itโ€™s one of the world’s largest air cleaning manufacturers, with a reported revenue of $19.2 million. What makes this brand stand out is that Austin Air purifiers use much more activated carbon than what is typically found in traditional consumer air purifiers, with around 15 lbs of carbon and zeolite in the HealthMate I am reviewing today.

While this means that Austin Air purifiers are among the highest-priced on the market, they are great at removing gases, odors and VOCs that standard air purifiers find much harder to remove. Austin Air was tested by the U.S. Army and fulfilled the largest deployment of air purifiers in American history to support the air quality concerns in post-9/11 NYC. 

As with every air purifier review we publish here at HouseFresh, we bought the Austin Air HealthMate Standard (B400B1) with our own money to remain unbiased.

The pros and cons of the Austin Air HealthMate

A summary of our top-level findings after testing this air purifier following our methodology.

Austin Healthmate TV Room

โ€œThe Austin Air HealthMate is the best air purifier on the market for dealing with severe air quality issues connected to chemical gasses, unwanted odors and VOCs.

However, with its 15 lbs of carbon and a price that surpasses $700, this device is overkill for those looking to keep dust and pollen levels low due to its high initial and running costs.โ€

& Lead Tester

CONS

At maximum fan speed, it pulls 148 watts which are on the higher side compared to similar-performing units,
It has no app support, on-board sensor or smart features.
At 61.5 dBA, it gets pretty loud when running at top speed.

PROS

It comes with 15 lbs of activated carbon with zeolite, which is the largest amount we have seen in a household air purifier.
Filters last five years before they need to be changed.
It has a one-dial operation that is easy to use right out of the box.
It comes on castor wheels that run well.

The best feature: a large amount of activated carbon and zeolite

The Austin Air HealthMate comes with a HEPA filter and a whooping 15 lbs of carbon and zeolite.

This is the largest amount of carbon we have encountered in a filter across the nearly 100 air purifiers we have tested.

However, at over $700, this air purifier will be out of budget for most people. That is why I particularly want to highlight it for those of you wanting to remove harmful VOCs and unwanted odors from your air, as that is the one use case where spending $700 will make the most sense.

Austin Healthmate Filter VS Core 300

Tip

The closest I can make would be the IQAir HealthPro Plus, which costs around $900 and also comes with powerful HEPA filtration and a gas filter that combines activated carbon and zeolite, too.

The one thing I will say about the HealthPro Plus is that it performed better in our particle removal test, cleaning the air of PM1 pollutants in 28 minutes compared to the 52 minutes it took for the Austin Air HealthMate to achieve the same result.

Now, the big difference between the two is that the HealthPro Plus comes with only 5 lbs of carbon compared to the 15 lbs of carbon you get with the HealthMate.

Design, controls and features

Functional design elements that do the job without any bells and whistles.

Austin Healthmate Front

The HealthMate is one of the largest air purifiers we tested, based on weight and dimensions.

The HealthMate has a simple 3-function switch for switching the unit on and for changing the fan speed.

Austin Healthmate Controls

The top of the device is flat and can make a handy side table:

Austin Healthmate Front

With a body made out of metal and a MASSIVE filter, this is a heavy air purifier that weighs 47 lbs (21.3 kg).

Austin Healthmate Living Room

Luckily, it comes on wheels that make it easy to move around the house.

Austin Healthmate Wheels

โ€œWith infrequent filter changes, the Austin Air is cheaper to own than almost every other heavy-carbon-HEPA air purifier on the market.

But at 45 pounds HealthMate NEEDS the four caster type wheels to get around, and may prove difficult for the elderly or infirm to move about the home, or upstairs.”

When it comes to its size, we’re talking about an air purifier that will need its fair share of space. However, when compared side-by-side with its biggest competitor (the IQAir HealthPro Plus), you can see that even though the HealthMate has a similar floor footprint but is a much shorter unit.

IQAir Healthpro Plus VS Austin Healthmate

Filtration technology

The Austin Air HealthMate comes with a True HEPA filter and 15 lbs of carbon + zeolite mix.

Austin Healthmate Filter Change

Most air purifiers use a HEPA-based filter with a small amount of activated carbon via impregnated fabric or small pellets. The reason that small amounts of carbon are used is down to price and can quickly increase costs for the initial unit and replacement filters.

If you are dealing with unwanted odors and VOCs, you need the biggest amount of activated carbon available. The filter inside the HealthMate comes with 15 lbs of activated carbon and zeolite.

Austin Healthmate Filter

It is worth mentioning that replacing the filter in the HealthMate is not as straightforward as with other air purifiers I have tested. You will need a screwdriver:

Austin Healthmate Accesing Filters

 

Once you have detached the top of the unit from its body, you will be able to access the filter. Here is how it looks inside:

Air cleaning performance

We tested the HealthMate in our 728 cubic ft. test room, tracking how fast it removed all PM1 particles from the air after we filled the space with incense stick.

Austin Healthmate Hallway

According to our PurpleAir Zen sensor, the HealthMate needed 52 minutes to achieve PM1 zero in our 728 cubic ft. test room. We estimate a PM1 CADR of 156 cfm.

But this information in isolation probably doesn’t mean much to you, so I made a table to show you how the performance of the Austin Air HealthMate compares to other devices we have tested:

AIR PURIFIER MODELTIME TO REACH PM1 ZERO AT FULL SPEEDLIST PRICE
Smart Air Blast Mini MKII15 minutes$649.00
Levoit EverestAir16 minutes$499.99
Alen BreatheSmart 45i30 minutes$429.00
Winix 5500-223 minutes$249.99
Rabbit Air A324 minutes$749.95
Coway Airmega AP-1512hh Mighty26 minutes$229.99
IQAir HealthPro Plus28 minutes$1000.00
AirDoctor 300030 minutes$519.00
Austin Air HealthMate52 minutes$756.00

If this air purifier were to have been designed with the focus of removing particles from the air, then the results could be seen as unimpressive, considering that it cleaned our test room at a similar rate to the Levoit Core 300 (54 minutes), which is available for $99.

But you must consider that the Austin Air is designed to remove gasses and VOCs due to its larger-than-normal activated carbon and zeolite filter. And the thing with large amounts of carbon is that they restrict airflow, so this will have an effect in the particle removal performance of this air purifier.

Luckily our upgraded Purple Air Indoor sensor has the latest BME68 sensor that allows us to also track the level of VOCs in the air. 

Removing gasses takes much longer and even with the large filter of the Austin Air HealthMate, you can see that VOC levels are drastically reduced over the next few hours after we perform our particle test. By 2 p.m., we had reduced the level of VOC from 433.65ppm to 50.52ppm. 

Sound levels

The sound levels of the Austin Air HealthMate range from 42 dBA to 61.5 dBA โ€” this matches what we saw with the IQAir HealthPro Plus (61.2 dBA at top speed).

As part of our testing, we use a sound level meter to measure how much noise each of the air purifiers we review generates at each fan speed.

SpeedSound Level
142.0 dB
253.2 dB
361.5 dB

This is how this compares to other devices we tested:

AIR PURIFIER MODELSOUND LEVEL AT TOP SPEED (dB) TIME TO CLEAN OUR TEST ROOM
Smart Air Blast Mini MKII56.3 dB15 minutes
Levoit EverestAir57.8 dB16 minutes
Coway Airmega AP-1512hh Mighty60.1 dB25 minutes
IQAir Healthpro Plus61.2 dB28 minutes
Austin Air HealthMate HM40061.5 dB52 minutes
AirDoctor 300063.6 dB20 minutes

The ability to remove VOCs will likely require a more substantial fan to push the air through the large filter, so more noise is expected. While itโ€™s not painfully loud, it would be too loud if you had to work in the same room. 

That being said, I know that noise is subjective. Have a listen for yourself so you can assess whether the Austin Air HealthMate is too noisy for you.

I re-tested the particle removal performance of the HealthMate at its only sub-45 dBA fan speed (speed 1 @ 42 dBA) and it needed 76 minutes to reach PM1 zero:

Long-term running costs

Running a Austin Air HealthMate will cost you $226.95 per year, combining energy consumption costs and filter replacement prices.

As with all the air purifier reviews we publish here at HouseFresh, we did the math to calculate how much you should budget to run this specific device for a year accounting for energy costs and filter replacement costs.

First, we used a power meter to measure just how much electricity the HealthMate consumes at each of its fan speeds:

Fan speedEnergy consumed
161.1 watts
285.05 watts
3147.6 watts

This means that it would cost you $163.95 in energy costs for a year, based on 24/7 usage at top speed at the average U.S. energy rate.

The replacement filters for the HealthMate costs a whopping price of $315. Luckily, you only need to replace the filter every five years, which will translate into $63 per year in filter replacement costs.

Check the table below to compare the yearly running costs of an Austin Air HealthMate with what you can expect to pay with other similarly-priced and popular air purifiers:

AIR PURIFIER MODELESTIMATED ELECTRICITY COST (per year) FILTER REPLACEMENT COST (per year)YEARLY MAINTENANCE COST
Coway Airmega AP-1512hh Mighty$83.64$39.99$123.63
Winix 5500-2$57.82$79.99$137.81
Levoit EverestAir$73.58$99.99 $173.57
Smart Air SA600$56.55$141.47$198.02
AirDoctor 3000$104.63 $178.00$282.63
Austin Air HealthMate$164.39$57.90$283.03
Smart Air Blast Mini MKII$136.29$236.99 $373.28
IQAir HealthPro Plus$221.47 $200.00$421.47

Bottom line: Should you get an Austin Air HealthMate?

This is the best air purifier on the market today if you have serious issues with VOCs or odors. Otherwise, you should look into cheaper units.

If you have health concerns that tie back to VOCs or are experiencing significant issues with gasses, you canโ€™t get much better than the Austin Air HealthMate and its 15 lbs of activated carbon and zeolite.

However, for the vast majority of use cases, spending $700+ on this device will be overkill and unnecessary.

Austin Healthmate Living Room

The HealthMate comes with much more activated carbon than the IQAir HealthPro Plus (5 lbs VS 15 lbs) and is cheaper to buy and run. But when it comes to particle removal performance, the HealthPro Plus will offer you better bang for your buck – even at its higher price.

So for those looking for the best air purifier for dealing with serious VOCs, then the Austin Air HealthMate is definitely a top contender. But if you are just looking for a good air purifier that will help with common kitchen odors, dust and pollen, then you will be able to find a device for a fraction of the price in our list of the best air purifiers we recommend right now.

And if you’re looking at the HealthMate because you’re looking for an air purifier made in the USA, then you should also check out the Luggable XL-7 from the team at CleanAirKits. It doesn’t come with activated carbon so it will be useless against odors and gases but its particle removal performance is INCREDIBLE, it is whisper quiet thanks to the use of PC fans AND all the DIY kits are made in the USA.

Levoit LV-H128 review

Levoit LV H128 Close Up

If you’re in the market for a quality air purifier, you may have encountered the Levoit brand. The company is based in the U.S. though its products are manufactured in China. 

With over ten years of experience in air purification, Levoit has become one of the best-selling air purifier brands in the U.S. and Canada, with over 3 million happy customers worldwide. 

Currently, they offer Core, LV-H, Vital, LV-PUR and Vista models, with Core and LV-H being the most popular. The Levoit LV-H128 is a budget-friendly option designed for small rooms. Like the Levoit Core Mini, the LV-H128 also has an aromatherapy function, so you can use essential oils while cleaning the air in your room. Itโ€™s also in the same price range as the Core Mini, so it will be interesting to see how the LV-H128โ€™s performance compares.

As with every product we review, we bought the Levoit LV-H128 with our own money so we could run our usual experiments on it with no strings attached.

The lowdown on the Levoit LV H128

danny

โ€œThe Levoit LV-H128 is a cheap air purifier at less than $50. Its small size makes it an easy unit to live with, but its air-cleaning performance is weak even for the smallest of rooms.โ€

โ€” Danny Ashton, Founder & Senior Writer

Short on time? Here’s my summary of the Levoit LV-H128:

What we really like

Very low initial price to buy the unit.
The compact design makes it easy to use in any type of room.
Quiet sleep mode โ€” produces only 28 dB.
Aromatherapy function allows you to use essential oils to create scent in your home.
Small footprint.

What we think could be better

Air cleaning performance is weak compared to other units at this price point.
The carbon filter is small and not as efficient as expected.

The Levoit LV-H128 is designed for small rooms of up to 47 sq. ft with 4.8 standard air changes per hour. Air cleaning power-wise, itโ€™s very similar to the Core Mini, which has a recommended room size of 50 ft2.

Small design and one-button control

The Levoit LV-H128 is one of the smallest air purifiers made by Levoit but is still much bigger than the smallest โ€” the Core Mini.

Levoit LV H128 Window

As you can see below, compared to the Core 300 and 200S, the LV-H128 is much smaller in height and floor space required.

Levoit Core 200 VS LV H128 VS Core 300

Additionally, the unit has a dedicated aromatherapy slot on the top corner, which has a sponge that soaks up essential oils.

Levoit LV H128 Diffuser

As clean air flows out of the air purifier, it passes through the oil-soaked sponge and diffuses the scent into the room.

Levoit LV H128 Top

The LV-H128 has straightforward controls consisting of a single button. This button doubles as the power button and cycles through the air purifier’s various fan speeds. The three-speed modes are high, low and sleep.

Not enough carbon to kill odors 

Filtration technology is the most crucial factor for you to consider when buying an air purifier. Some filters can remove up to 99.99% of pollutants, while others emit chemical byproducts. 

Some can remove VOCs and odors, while others aren’t effective in this area.

So, how does the Levoit LV-H128 fair in this department?

Levoit LV H128 Filters Close Up

The LV-H128 features Levoitโ€™s popular three-stage filtration system. 

  • Pre-filter โ€” Traps large particles, like hair, fur and lint, from going further into the purifier
  • Main filter โ€”  Traps 99.97% of particles down to 0.3 microns, like dust, pollen, mold, bacteria and pet dander.
  • Activated Carbon filter โ€” Absorbs odors. I was disappointed to see this was made from a cheaper impregnated fabric instead of the pellets you get in the Levoit Core series
Levoit LV H128 Filters

It’s worth mentioning that the third layer doesn’t contain enough carbon to remove odors, so the LV-H128 isnโ€™t a unit I would recommend for those with issues with odors or gasses. 

โš ๏ธ Most new air purifiers come with the HEPA filter covered in plastic. Remove it before you start the unit; otherwise, it wonโ€™t work.

The Levoit LV-H128 cleared our test room in 86 minutes

At HouseFresh we aim to provide an unbiased opinion about the performance of the air purifiers we review. To achieve this, we check the CADR ratings and metrics the manufacturer lists, but we take each figure with a grain of salt. 

We know that some manufacturers are notorious for including misleading information to increase the popularity of their products. For this reason, we buy each unit so we can test their performance in our own home lab, which measures 728 cubic feet.

We burn incense sticks to fill the room with smoke pollutants and use our indoor air sensor from Purpleair to see how fast their purifier can eliminate PM10.0 ug/m3, PM2.5ug/m3 and PM1.0ug/m3 particles from the indoor air. 

You can see the results of this test in the chart below:

Air cleaning performance test results

The LV-H128 through took 1 hour and 26 minutes to remove all pollutants of PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3 from the indoor air. The $59 Levoit Core Mini took 1 hour and 53 minutes, with a 27-minute difference.

Itโ€™s worth mentioning that while the LV-H128 is not the fastest unit we’ve tested, it did manage to remove these pollutants from the air. 

Noise levels test results

In terms of sound levels, the Levoit LV-H128 is a quiet unit. At maximum fan speed, it produces 46 dB โ€” higher than the Core Mini, which operates at 44 dB. However, this unit can go very quiet at the lowest fan speed, producing a mere 37 dB of noise.

The cost to run a Levoit LV-H128: $62.93 per year

Another vital factor to consider when buying an air purifier is the overall cost of running the unit in the long term as you will need to pay for electricity and filter replacements.

1. Electricity Costs = $14.95

This unit has a minimal power consumption of just 10w on average, which makes sense considering its size and coverage.

At the highest speed, we saw that it pulled 9.8 watts, which equates to $14.95 per year at 24/7 usage every day. The newer Levoit Core Mini was slower but only pulled 6.4 watts at the highest speed.

2. Filter Costs = $47.98

Filter costs are another essential factor when buying an air purifier. The LV-128โ€™s HEPA filters should be replaced every six months. 

The genuine Levoit LV-H128 filters cost $23.99, which is $47.98 per year, but you can find generic filters for $11.34 per year with two changes. Thatโ€™s a much better choice for most people.

Bottom line

The Levoit LV-H128 is an underpowered air purifier. Out of all the units we have tested, this one took one of the longest times to remove all the pollutants in our test โ€” needing a whopping 1 hour and 26 minutes. 

The aromatherapy function might be a nice touch for some users, but it doesn’t change the fact that this air purifier will be too underpowered for most scenarios. 

Levoit LV H128 Window

Genuine filter costs are high when considering the cleaning power, but you can get very cheap generic ones at just over $5. 

Most people will be much better off with the Levoit Core 300. Itโ€™s more expensive to buy, but will be far more effective at cleaning the air and has similar long-term costs to the LV-H128.

hOmeLabs 4000 Sq. Ft. 50 pint dehumidifier review

hOmeLabs 4000 sq ft Living Room

hOmeLabs is a brand managed by Aterian that is listed on the Nasdaq and is responsible for 2000 products ranging from dehumidifiers to air purifiers. I first became aware of the hOmelabs 50-pint model with a pump when I analyzed the best-selling dehumidifiers on Amazon. 

This model stood out as the biggest seller of last year with over 40k reviews with an average review of 4.7 โ€” not easy for a product like a dehumidifier prone to faults. The main aim of this specific model is to bring a high capacity of dehumidification, including a pump but for far less money than you would usually pay. 

The hOmelabs 50-pint with pump can often be found for less than $250, while a similar unit from a brand like Honeywell with the same size and pump is over $350. hOmeLabs promises the same level of performance for $100 less, so I was super excited to test it for myself and see if it lives up to the hype.ย 

  1. We set up the dehumidifier inside our very humid basement of 2,000 sq. ft.
  2. We set up our trusted SensorPush wireless hygrometer to track humidity levels in the air every minute while the dehumidifier is running.

The lowdown on the hOmeLabs 4000 sq. ft. dehumidifier

danny

โ€œTop-level performance for $250 typically only found in the $350+ range. If you have a damp basement and can use the pump, this is the dehumidifier to get in 2023โ€โ€” Danny Ashton, Founder & Senior Writer


Donโ€™t want to read my full review? Then get my low down on what I think about the hOmeLabs dehumidifier:

What we really like

50 pints of water removed for $100 less than the competition
Uses less power compared to other models with the same capability – 520 watts vs. 700
The hose is long enough for most situations
Size is easy to live with and comes with wheels for easy moving around
Sound level of 53dB is easy to live with and is much lower than many similar dehumidifiers on the market

What we think could be better

It lacks a carry handle which would make it easier to move to different rooms
No smart mode or app support
Water tank capacity is smaller than other units at this performance level, so less attractive to those who will not be able to utilize the pump and hose
Six months after using the hOmeLabs in my basement, the internal pump started to fail and the hose was unusable due to the amount of mold growing inside of it

The specifications

This model stands out with the amount of dehumidification power for far less money than many other competitors with similar specs:

HouseFresh rating:โ˜…โ˜…โ˜…โœฉโœฉ
Water removal in 24 hours (2019 DOE Standard):50 pints
Water tank capacity:7 pints
Recommended room size:Up to 4000 sq. ft.
Noise level full power:53dB
Dimensions (in inches / in cm):11.75D x 15.75W x 25.3H inches (30D x 40W x 64H cm)
Weight (in pounds / in kg):42.50 lbs (19.3kg)
Energy consumption:520 watts (or $44 per month)

Looks good, and itโ€™s easy to use

hOmeLabs 4000 sq ft Front

Any dehumidifier is unlikely to win a design award, but the hOmeLabs 50-pint with pump looks good and has a super simple menu system. You can change the humidification target level at 1% variations.

hOmeLabs 4000 sq ft Top

I preferred the hOmeLabs menu to the Honeywell, as I found the icon-only buttons unclear with the Honeywell model. The hOmeLab uses text and icons, and I could quickly know what each button did without requiring me to check the web.

The hOmeLabs dehumidifier has a high-quality mesh that stops large particles and insects from entering the cooling coils. There is also an alert to inform you when to keep this clean, which alerts me every three months.

hOmeLabs 4000 sq ft Grill

Unlike other dehumidifiers we have tested, this unit doesnโ€™t use any filter beyond the dust/insect mesh, and I donโ€™t think this is such a bad thing. The main goal of a dehumidifier is to reduce humidity; if you are looking to clean the air of pollutants or odors, then you are much better off with a dedicated air purifier. 

No need to drain daily

One of the highlights of this particular unit was the inclusion of the pump.

hOmeLabs 4000 sq ft Tube Close Up

If you have ever used a dehumidifier, you will know that a real pain can be emptying the water bucket daily. This is fine for smaller rooms like a bathroom, but for a basement with a significant damp issue, you might be draining the water twice daily with a unit that can pull out 50 pints of water in 24 hours.

hOmeLabs 4000 sq ft Water tray

This dehumidifier comes with an extended 16.4ft hose that is long enough for most situations; I was able to have mine pump out water to a drain outside my basement.

hOmeLabs 4000 sq ft Attach tube

You need to connect the hose to the connector at the back and press the pump button when using the pump. The pump means that you can have the hose go higher as it will not require gravity, as you will be able to pump the water to another location.

Tip

You can use this model without the pump if youโ€™re not planning to place it in a humid room. However, in that case, you should probably go with a smaller dehumidifier without a pump, as it will be cheaper.

Intuitive control panel

The display screen shows the room’s current humidity level and you can then set your preferred target humidity up to a maximum of 80%. Once the dehumidifier detects hitting the desired humidity level, it automatically reduces power levels and the electricity you use.

hOmeLabs 4000 sq ft Controls

The pump button is vital if you want to use the pump as you need to press it, or the unit will just use the water tank. 

The timer allows you to have the dehumidifier on for a set amount of time, from 1-24 hours, which will switch off the dehumidifier after a set time. Iโ€™m sure this might have some use case. 

Personally, I prefer to set the humidity rate and let the machine decide when to be on or off. 

The hOmeLabs 4,000 sq ft lowered humidity levels in my basement within two weeks

This hOmeLabs dehumidifier can work up to 4000 square feet, so I tried it in my 2000 square foot very damp basement. My house is relatively old, so the basement gets very damp (90%+), so this is an excellent test for a unit with this level of performance. 

I set up the unit with the included hose, which is long enough to connect to an outside pipe and drain. This is great as all the water absorbed from the air is pumped outside without the need of emptying the tank continuously. I had previously tested other smaller units in my basement and found I was emptying the tank twice per day, which was a pain and usually led to me spilling a little water every time.

To test the level of the humidifier, I used my Govee WIFI humidity sensor, which allows me to track the humidifier over time and export the data to show the change over time. 

Before turning on the hOmeLabs, my basement showed 90+% humidity, so I set the hOmeLabs to 65% to see if we could hold this humidity level in the short and long term.

I switched on the dehumidifier on the 8th of October 2022, and you can see how quickly it reduced the initial humidity level from 90% down to the desired 65% by the 15th of October. Within two weeks, I saw significantly lower humidity levels. 

Once it reached 65%, I didnโ€™t switch off the unit. You can see how effectively it kept my basementโ€™s humidity levels in the 50-60% range, which is much healthier than before. My wife, who suffers from asthma, now finds it much easier to spend time in the basement when before, she would have problems after just a few minutes down there.

I ran the test for a number of months (between October and January) and in that time, I had two alerts to clean the filters and no issues with the pump or with the unit switching off, even when we went away for four weeks along the way.

Overall, I was super happy with its dehumidification performance both in the short and long term. 

Noise levels test results

The hOmeLabs 50-pint dehumidifier has a maximum sound level of 53dB, similar to a refrigerator. While certainly not silent, it doesnโ€™t stand out too much. Use a dehumidifier using a target humidifier level. 

You will find that the unit is not on full power all the time except when itโ€™s used for the first time and will often come on and off as needed, which helps to reduce the amount of sound generated. 

Sound levels are always personal, so we have produced a short video of what our hOmeLabs dehumidifier sounds like in our basement:

The cost to run a hOmeLabs 4,000 sq. ft. dehumidifier:  $528 per year

hOmeLabs 4000 sq ft Energy

The maximum amount of power that this dehumidifier will draw from the power is 520 watts, which, if we assume itโ€™s using this level of power all the time, will equate to $44 per month according to the Department of Energyโ€™s appliance energy calculator.

When not running at full power (once humidity levels had been reached) the dehumidifier used between 14.9 watts at the lowest and 74.7 watts at the highest โ€” much less than what you will see when you first use the dehumidifier in a very damp location, but something to consider when using longterm as it wonโ€™t cost as much as you might think.

hOmeLabs 4000 sq ft Power Usage

Dehumidifiers can certainly use a lot more power than many people expect. Still, for many uses, the unit will not draw maximum capacity as it will switch to a lower power mode when it reaches the level of humidification required.

Bottom line

I had high hopes for the hOmeLabs 50-pint with pump dehumidifier and Iโ€™m glad to say that it met those expectations. Certainly, there could be some improvements made to its pump and hose and it would also be good to see this unit come with a handle and an app for your smartphone. 

Still, for the price, itโ€™s hard not to recommend this dehumidifier for any homeowner with a damp room that can utilize the pump function. It does the job well, is easy to live with the sound levels and wonโ€™t cost too much electricity. 

hOmeLabs 4000 sq ft Front 01

Its main competitor is the Honeywell  [TP70PWK] dehumidifier, which has a handle and higher capacity for removing water but, at $100, is a hard choice over this hOmeLabs model. 

SOURCES

We calculated the monthly energy consumption costs using the Department of Energyโ€™s appliance energy calculator. We calculated yearly costs associated with running the hOmeLabs humidifier for 24hs a day for 365 days. We ran this calculation using the U.S. average utility rate of $0.12/kWh as of April 2023.

Blueair Pure Fan Auto Review

Blueair Pure Fan Auto Hallway

Blueair is one of the big names in the air purifier industry; it has been designing and manufacturing air purifiers since 2016. 

Since 2016, the company has been owned by Unilever; as of this year, it is now a Certified B Corporation. Since the sale, Blueair has been rapidly bringing out new units, and this Pure Fan Auto is their first attempt at an air purifier and fan combo. 

Previously the โ€œfan + air purifier comboโ€ market has been dominated by Dyson with their HP04 and HP03 that bring air purifier functionality to heaters, fans and even humidifiers. 

The Pure Fan Auto combines the features of an air purifier with a fan and is aimed at capturing some of the markets that Dyson has built.

We liked the Dyson fan + air purifier combos but felt that the air cleaning performance could be improved, so we were excited to see how the Blueair Pure Fan Auto performed. 

The lowdown on the Blueair Pure Fan Auto

danny

โ€œA powerful air purifier that is perfect for problems with pollen or dust but is slightly let down by the fan performance and its lack of activated charcoal filter.โ€

โ€” Danny Ashton, Founder & Senior Writer

Blueair Pure Fan Auto Hallway

If you prefer a quick overview of the Blueair Pure Fan Auto, these are the key takeaways.

What we really like

Powerful air cleaning performance โ€” it cleaned our test room in 26 minutes, which was only two minutes less than the IQAir Healthpro Plus.
Design is much better than what you usually see with air purifiers and could be a conversation piece.
Low long-term running costs.
Much smaller and easy to live with compared to other air purifiers with this level of air cleaning power.

What we think could be better

Lack of activated charcoal means it will not do anything for odors, gasses or VOCs.
Fan performance is much weaker than the Dyson combo units.
No app support or smart features beyond the auto-mode.

The specifications

The Blue Pure Fan Auto brings a high level of CADR without the usual high energy usage and sound generated that we see with units like the IQAir Healthpro Plus or Mila Air Purifier.

See the full specs for the Blue Pure Fan Auto below:

A functional art piece with simple controls

Blueair knows that design is super important to their customers. They have been continually investing in this over the past few years. Iโ€™m just going to say it: the Pure Fan Auto is one of the best-looking air purifiers that I have had a chance to review.

Blueair Pure Fan Auto Front

Its cube shape makes it easy to use in many places around the home, and doesnโ€™t even need to sit directly on the floor.

Blueair Pure Fan Auto Legs Close Up

The legs look like something from a high-end piece of furniture and even the fan holes’ design is aesthetically pleasing. 

Blueair Pure Fan Auto Grill Close Up

The auto mode includes a light in the top left-hand corner that adjusts depending on the level of particle pollution. The fan will also automatically adjust to provide more cleaning power depending on the level of air quality detected. 

If I wanted to compare the design and aesthetics of Blue Fan Auto with a similar unit, then I would need to look at the Dyson range of fan-air purifier combos. Personally, I prefer the looks of the Blueair unit as it fits my home interiors better and blends into the furniture we already have BUT I know thatโ€™s a personal preference.

Objectively, you can see in the image below how the Dyson combo units are considerably bigger (and heavier) and must be kept on the floor. 

Blueair Pure Fan Auto VS Dyson Fan Combo

After living with all three of these combo units in my own home, I can say that the Pure Fan Auto is a much easier air purifier to live with. You can tuck it away and it doesnโ€™t take a lot of space.

Plus, it comes with a leather carry handle, making it way easier to move to different locations around the house when compared to the chunkier Dyson units.

Blueair Pure Fan Auto Handle

As with the other Blueair purifiers we have reviewed, the control panel is super simple, with one button to turn it on and a fan button to adjust the fan speed, enable auto-mode and switch it to sleep mode. 

Blueair Pure Fan Auto Controls

I would have liked to have seen the ability to enable a sleep mode (lights off) that still works with the higher fan speeds. The sleep mode switches all the lights off but is restricted to a  low fan speed mode.

HEPASilent that lives up to its name

The Blueair Pure Fan Auto uses a HEPASilent system that combines an electrostatic charge with a HEPA filter that allows it to hit a CADR of 250 CFM, which is impressive considering it only draws 40.9 watts at full speed. 

Blueair Pure Fan Auto HEPA top

The main thing I noticed with the filter for the Blue Pure Fan Auto was the lack of activated charcoal. While HEPASilent will be super effective with dust or pollen, any issues with odors or VOCs will not be dealt with. 

As with other Blueair models of air purifiers, you can change the pre-filter color with five options.

Blueair Pure Fan Auto Pre filter

I would like a combined filter in future versions, as we saw with the Blue Pure 411+, including fabric impregnated with activated charcoal and HEPA.

As with all HEPA filters, Pure Fan Auto will need its filters replaced every 6 months as particles become trapped in the filter and eventually cause a reduction in the air cleaning performance. 

โš ๏ธ The filters for the Pure Fan Auto are delivered in a plastic bag, so be sure to remove this before you switch it on. Otherwise, the unit will do nothing to clean your air.

The Pure Fan Auto cleared our test room in 26 minutes

The main thing to look for when buying an air purifier is how well it can remove particles from the air, so we donโ€™t just trust what manufacturers tell us; we test it for ourselves. 

We simulate particle pollution by burning an incense stick in our 728 cubic ft test room and use our PurpleAir Indoor sensor to continuously track PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3.

Air cleaning performance test results

The Pure Fan Auto managed to clean our test room in 26 minutes which compares very favorably with the Dyson Combo units like the HP04, which cleaned in 84 minutes and the PH03, which took 70 minutes. 

The Pure Fan Auto took only two more minutes than the $700 IQAir HealthPro Plus and was one minute quicker than the Winix 5300-2.

For pure cleaning power, the power the Pure Fan Auto compares favorably with many air purifiers that donโ€™t have any fan capabilities. 

How did the fan perform?

As the Blueair Pure Fan Auto is not just an air purifier, we wanted to see how its fan functionality performed compared to other combo units like the Dyson range of fan/air purifiers.

Blueair Pure Fan Auto Fan speed test

We tested flow velocity using the Testo 4101 Wireless Anemometer at 3ft from the fan. Over 30 seconds, we saw the following flow velocity measurements for the Pure Fan Auto compared with the Dyson HP04:

Blueair Pure Fan Auto Dyson HP04
Overall average0.74 m/s2.61 m/s
Minimum total0.51 m/s2.26 m/s
Maximum total0.99 m/s2.91 m/s

We can see that the Dyson provided over 3.5 times the airflow when 3ft away from the fan. 

So while the Pure Fan Auto performs much better as an air purifier, the Dyson has much better fan performance.

Noise levels test results

At its lowest speed, Pure Fan Auto only produced 37.8 dB – as silent as a quiet library. When turning the unit up to its highest fan speed, it hit 59.6 dB, which is the sound of a conversation or that of music playing in the background.

Sound is lower than the IQAir Healthpro Plus, which hits 61.2 dB. It’s also much lower than the Molekule Mini, which hits 68 dB.

The cost to run a Blueair Pure Fan Auto: $85.61 per year

1. Electricity costs = $62.38

Energy costs will not decrease anytime soon, so we feel itโ€™s essential to monitor how much energy is used, as air purifiers are often needed 24/7 to keep your air continuously clean. 

The Pure Fan Auto compares very favorably with many units with a similar cleaning performance with only 40.9 watts at full power. Other units with similar CADR, such as the Coway Airmega AP-1512hh Mighty or the Winix 5300-2, draw 75.3 watts and 51, respectively.

2. Filter costs = $23.23

HEPA is designed to be replaced, as the particles are held inside the fiber material and at a certain point become so full of particles that it will lead to reduced air cleaning performance. 

The cost of authentic filters is lower than that of other air purifiers with similar air cleaning performance. You can even reduce this further with generic filters that cost $29.49 for one year with two filter changes.

Bottom Line

The Pure Fan Auto finally brings a high air cleaning performance with fan functionality. As with many modern Blueair air purifiers, it uses a low level of electricity to clean a lot of air without leading to lots of noise generated. 

Blueair Pure Fan Auto Living Room

If youโ€™re looking to replace a fan used in the bedroom, the Pure Fan Auto should be at the top of your list. The only downside is the lack of activated charcoal and the fan speed, which is much less than what you see with the Dyson units, which are great fans but poor air purifiers.

We calculated yearly costs associated with running the Blueair Pure Fan Auto 24 hours a day, 365 days per year utilizing the latest average energy prices as reported by the Bureau of Labor Statistics of $0.174/kWh as of April 2024.

TaoTronics AP005 review

Taotronics AP 005 Front Room

Since its inception in 2007, TaoTronics has made giant strides in consumer electronics, offering air purifiers, kitchen appliances and audio devices. The company is based in Shenzhen, China and its products are available in countries like Japan, Singapore, Germany and the U.S.

Theyโ€™re famous for their true wireless earbuds and powerful air purifiers, including the TaoTronics AP003 โ€” our best air purifier of 2022. 

As a Chinese manufacturer who sells directly to the U.S., they donโ€™t waste money on marketing, with their value proposition defined by their low cost. They currently have various air purifiers/fan combo units, including the AP001, AP005 and AP008. 

Owing to the exceptional performance of the AP003, we decided to buy the AP005 and put it to the test in real-life situations. Keep reading to learn more about the test results and see how it compares with our tested units.

TL;DR The lowdown on the TaoTronics AP005

danny

โ€œA powerful air purifier for the budget, but I would still prefer the slightly bigger AP003 model.โ€

โ€” Danny Ashton, Founder & Senior Writer

TaoTronics AP005 Bedroom

If you donโ€™t want to read the full review of the TaoTronics AP005, you can focus on the pros and cons:

What we really like

Smart auto mode for real-time air quality monitoring.
An easy-to-read color-coded system.
Small and compact design.
Three-stage filtration system.
Affordable at just $65.

What we think could be better

No mobile app.
Carbon filter used impregnated fabric vs. pellets that we prefer.
Not easy to find a unit you can buy via Amazon.

The specifications

The great thing about TaoTronics is that they offer affordable air purifiers with features youโ€™d expect in highly-priced models. At $65 for CADR 147 CFM, the AP005 provides excellent value for money compared to units with similar performance, like the Levoit Core 300.

Small footprint and easy-to-use controls

The TaoTronics AP005 is a cylindrical unit like its bigger brother, the AP003. The cylindrical design allows for a small footprint, which made it easier for me to use in different rooms without needing to move the furniture. 

TaoTronics AP005 Laundry room

The AP005 draws in air from the bottom, sucks it through the inner filter and expels it from the top. Tiny, numerous circular holes perforate the front and back of this unit, feeding air to the 3-stage filtration system. This efficient design allows for an even distribution of clean air. 

At the top, youโ€™ll find all of the TaoTronics AP005 controls. The control scheme is simple, with six touch buttons that are appropriately labeled to avoid confusion. At the bottom of the panel is a simple power button with an LED indicator. 

TaoTronics AP005 Controls

To the left side of the panel is a timer and filter indicator button. The timer automatically allows you to select your desired operation time for the device to turn off after the specified duration. The filter button illuminates when the filters need replacement. 

To the right are the speed and light buttons. The speed button lets you change the fan speed while the light button cycles through the different LED light levels: poor air quality, good air quality, and excellent air quality.

TaoTronics AP005 Air Quality Sensor

๐Ÿ’ก At the top is a lock button that disables the deviceโ€™s control panel to avoid unintended pressing.

Measuring 14.9H x 8.8W x 8.8D inches (37.8H x 22.4W x 22.4D cm), the AP005 is virtually the same size as the Levoit Core 300:

TaoTronics AP005 VS Levoit Core 300

If youโ€™re between the TaoTronics AP003 and the AP005, it will be useful to see the size difference between both units – you will need to have a lot more space in the room for the AP003:

TaoTronics AP005 VS TaoTronics AP003

Industry-grade air filtration system

I love that the TaoTronics AP005 uses industry-grade H13 True HEPA and Activated Carbon filters that donโ€™t produce harmful by-products like ozone โค๏ธ.

TaoTronics AP005 HEPA Filter

The TaoTronics AP005 features a 3-stage filtration system. 

  • Pre-filter โ€” Traps large particles such as hair, pet fur and lint
  • H13 True HEPA filter โ€” filters 99.97% of particles down to 0.3 microns, like dust, dander, pollen, mold and germs.
  • Activated Carbon filter โ€” Absorbs odors and harmful gases

Removing the filters is easy and can be done in three simple steps. Simply flip over and twist the filter cover indicator filter to open, remove the old filter and replace it with the new one, then align the triangle marks and twist the indicator to lock, and youโ€™re good to go. 

TaoTronics AP005 Replace Filter

Still unsure of how to do it? Check out this step-by-step video:

So, a recap, two more things I like about this unit: the filters are easy to remove, and filter replacements are readily available. 

โš ๏ธ New air purifiers will come with the HEPA filter covered in plastic or inside a plastic bag. Remove this before you start the unit; otherwise, it wonโ€™t work.

The TaoTronics AP005 cleared our test room in 36 minutes

The TaoTronics AP005 removed all pollutants in our 728 cubic feet test room in just 36 minutes. 

๐Ÿ’ต This puts the AP005 on our list of the top recommended models for those on a tight budget. 

As mentioned, we burn incense sticks and use our indoor sensor from Purpleair to track PM10.0 ug/m3, PM2.5ug/m3 and PM1.0ug/m3 levels in a controlled environment to see how fast an air purifier can remove all these pollutants from the indoor air.

As you can see from the graph, the AP005 cleared our test room in just 36 minutes, with PM10.0ug/m3 and PM2.5ug/m3 and levels dropping fast from the moment the device was turned on. 

Air cleaning performance test results

In terms of air cleaning performance and speed, it compared favorably with other units in its same price range such as the Levoit Core 300S.

When it comes to noise levels, the TaoTronics AP005 didnโ€™t disappoint. How much noise does it produce when operating at minimum and maximum fan speeds?

Noise levels test results

In our testing, the TaoTronics AP005 sound levels ranged from 25dB at the lowest fan speed to 50dB at the highest. This is pretty good compared to other air purifiers weโ€™ve tested. 

The TaoTronics AP005 compares favorably to many of the other units we have tested and is one of the quietest at its maximum speed. Take a listen for yourself:

The cost to run a TaoTronics AP005: $80.67 per year

1. Electricity costs = $44.69 per year

When buying an air purifier, youโ€™ll need to factor in the cost of running the unit, especially considering the rising electricity costs.  The good news is that the TaoTronics AP005 is a fairly efficient device. 

Our electricity usage monitor showed that the AP005 pulls 29.3 watts at full power, amounting to $44.69 a year, running it non-stop. 

In comparison, the Core 300 pulls 35.5 watts at maximum power, equating to $54.15 per year. 

2. Filter costs = $35.98 per year

Filter costs are another essential factor when buying an air purifier. HEPA and Activated Carbon filters work by removing pollutants from the indoor air and over time, these filters wear out and need to be replaced. 

Genuine filters for the AP005 cost $17.99 and must be replaced twice yearly. In comparison, you pay $34.99 for genuine TaoTronics AP003 replacement filters and $60 for the Levoit Core 300. 

Flintar TT-AP005 Replacement Filter, Compatible with TaoTronics TT-AP005 Air Purifier, H13 Grade Filtration and Activated Carbon Filter Set, 2-Pack
  • Contains Two (2) packs of premium 3-in-1 filtration system including Pre-Filter, H13 Grade Main Filter, and High-Efficiency Activated Carbon Filter
  • Pre-filter traps larger particles in the air like hair, dust, pet fur, lint and more
  • Activated Carbon Filter absorbs household odors from pets, cooking, smoking, wildfire, and harmful VOCโ€™s
  • H13 Grade Main Filter captures 99.97% of airborne particles down to 0.3 microns in size, creating fresh and purified air for you and your family
  • Easy to replace and disposable, no tools required. Replace the 3-in-1 filter every 3-6 months depending on the usage and environment


Bottom line

The TaoTronics AP005 is a cheap air purifier that can do a great job at removing particles from the air in small to medium-sized rooms. 

Itโ€™s a very effective air purifier for the price, although the lack of pelleted carbon means we would recommend the AP003 over it or the Levoit Core 300 as it will be more effective for odor and gasses.

Levoit is a company from the USA that manufactures all its units in China and they are part of Vesync Co Ltd, a publicly traded company with 1,200 employees. Itโ€™s been a significant player in the United States for budget air purifiers since it entered the market in 2017.

The Levoit LV-H132 was the first model that Levoit brought to market when it launched in 2017. It was designed as a smaller/budget-friendly air purifier for small spaces of up to 129 ftยฒ.  There are no timers, auto-mode and app support โ€” all things you find with newer Core Model S units. 

The Levoit Core 300 is one of my favorite air purifiers at HouseFresh, so we were excited to review the LV-H132.ย 

As with all our reviews here at HouseFresh, we bought the Levoit LV-H132 with our money. That means we can tell you precisely what we think. We always do our desk research, but when it comes to reviewing air purifiers, you need a way to compare performance. We have a simple way to compare performance across all different types of air purifiers that you donโ€™t need a Ph.D. to understand.ย

The lowdown on the Levoit LV-H132

โ€œIt has the same long-term cost as other Levoit units but with far less cleaning power. You can get much better performance with the Levoit Core 200S.โ€

PRICE on amazon PRICE on EBAY

If you donโ€™t want to read my full review, then here is my rundown on the LV-H132:

What we really like

Simple controls and light on top are an excellent design touch.
The initial cost is fair at under $70.
Generic filters are available that allow you to run it for just over $30 per year.
Sound levels are acceptable and very quiet at the lowest speed.
Filter light is appreciated and will allow for better long-term performance.

What we think could be better

Air cleaning performance is sub-par for this budget and would struggle with even the smallest rooms.
Efficiency is lower than other Levoit products, such as the Core Mini or Core 200S.
Long-term costs are high when you consider you can pay similar for twice the cleaning power with something like the Levoit Core 300.

Often found retailing for $70-$80, this is one of the cheapest air purifiers sold by Levoit.

Small design and simple controls

The stand-out design feature is the light in the middle of the purifier, which could act as a night light.

Levoit LV H132 Close Up

The LV-H132 has a simple control system โ€” a power on/off button, night light and fan speed button with three different speeds available. 

Levoit LV H132 Controls

You will notice that the third button shows an icon for the HEPA filters. This will turn on when itโ€™s time for you to replace the filters in the unit.

Once you have replaced your filters, the filter warning light can be reset if you hold it down for several seconds.

Limited filtration system that is not good enough

The LV-H132 includes the 3-stage filtration technology Levoit offers in all its units.

Levoit LV H132 Filter Removal

The filter in the LV-H132 includes a pre-filter cover that can be removed to expose the H13 True HEPA filter with an integrated activated carbon filter.

The main feature of the filter is the powerful medical-grade HEPA H13. However, due to its small size, the LV-H132 wonโ€™t be as powerful as other Levoit units when dealing with pollutants. That said, it gets the job done.

Levoit LV H132 HEPA Filter

A carbon filter is integrated, which will come in handy for combating gasses and odors. Similarly to the HEPA filter, the carbon filter is much smaller than those in units like the Core 300

The good news is that the LV-H132โ€™s carbon filter uses activated pellets โ€” better than many other budget units that use impregnated fabric.

Levoit LV H132 Carbon Filter

When it comes to replacing the filter, you will unlikely have any issues as the process is quite straightforward.ย 

You can watch this video to see how itโ€™s done:

Due to the small size of the LV-H132, it is limited in the number of pollutants it can remove, especially when compared to larger units. While we appreciate the use of pelleted charcoal, itโ€™s still minimal and is unlikely to significantly impact the amount of VOCs or odors in the air.ย 

Tip

New air purifiers will come with the HEPA filter covered in plastic or inside a plastic bag. Remove this before you start the unit; otherwise, it wonโ€™t work.

The Levoit LV-H132 cleared our test room in 98 minutes

We had high hopes for the LV-H132, considering how often it is recommended by big media sites, but it just didn’t deliver

We tested the LV-H132 following the same process for all other air purifiers we reviewed. We placed it in our 705 cubic ft test room, used an incense stick to generate smoke pollutants and then turned on the LV-H132 at full speed.

We used our PurpleAir indoor sensor to track PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3 to time how quickly the air purifier brought the level of pollutants back to 0.

Have a look for yourself:

It took 98 minutes to fully remove all the pollutants in our test room. 

Air cleaning speed, compared

This was much longer than the $99 Levoit Core 300, which took 40 minutes and was close to the much smaller and cheaper Levoit Core Mini, which took 113 minutes. Interestingly the Levoit Core 200S has the same price as the LV-H132 but took 61 minutes to clean our test room. 

At this level of cleaning performance and this price, itโ€™s tough to recommend the LV-H132 even for a small room, as consumers would get more bang for their buck with the Core 200S or even more with the Core 300 for just a little extra spent initially.

Noise levels, compared

As with many small air purifiers, at its lowest speed, the LV-H132 doesnโ€™t generate much noise at 25dB, but it reaches the same levels as the large Core 300 at the highest speed with 50dB of sound generated. 

We always like to record videos showing sound levels as noise can be subjective. Listen to the LV-H132 for yourself:

The cost to run a Levoit LV-H132: $70.36 per year

1. Electricity costs = $28.38 per year

The LV-H132 is now an older unit compared to the Core series of air purifiers and it shows with its energy usage. At its highest speed, we saw that it drew 26.7 watts, while the newer Levoit Core 300S managed to clean much quicker, which pulled only 14.6 watts. 

When calculating how much it would be added to your electricity bill if you ran the LV-H132 continuously 24/7, the final figure is quite reasonable at $28.38. I would still prefer to choose a more efficient unit like the Core 200S that uses the same amount of power but cleans our room 37 minutes quicker.

2. Filter costs = $45.98 per year

Filters directly from Levoit cost $20.99 per filter, which comes to $41.98 per year. For reference, the filters for the Levoit Core 200S cost $45.74, and the ones for the Core 300S costs $60.

One of the big benefits of a popular brand like Levoit is that you can often find many generic filters available at a lower cost. We found a generic filter set for the LV-H132 that brings total yearly costs down to $32 per year.

Bottom line: Is the Levoit LV-H132 worth it?

This cheap unit will cost you in the long run, and it won’t do a good job at cleaning your air

When the LV-H132 was first released in 2018, it wouldโ€™ve been a decent unit for those on a budget. As of right now, there are far too many high-performing budget air purifiers like the Levoit Core 300S or Taotronics AP003 that clean far more air and cost a similar amount both in initial machine cost and long-term costs in filters and electricity.

Levoit LV H132 Bedroom

If you need an air purifier for a small room, we would suggest looking at other units like the Levoit Core 200S at the same cost and, if possible, you should consider spending a little more for a large unit like the Levoit Core 300 or Taotronics AP003 that would cost the same in energy and filters but would be able to keep your air clean much cleaner.


SOURCES

We used the Department of Energyโ€™s appliance energy calculator to calculate yearly costs associated with running the Levo LVโ€“H132 for 24hs a day for 365 days. We ran this calculation utilizing the US average utility rate of $0.12/kWh as of 3rd March 2023.

Levoit Core Mini review

Levoit Core Mini Living Room Shelf NO LOGO

Levoit is currently one of three brands for Vesync Co which has offices in Los Angeles, USA, Shenzhen and Hong Kong, China, and is traded on the Hong Kong Stock Exchange. Running since 2012, its revenue last year was $458 million, and it has 1.24k employees, according to financial data.

The Levoit Core series really changed up the game in the world of air purifiers back in the late 2010s. Previously, cheaper units performed poorly and it was often better to recommend consumers avoid them. With the Levoit Core 300, Levoit brought a really good CADR score for less than $100 and forced other manufacturers to improve their game. Unlike many cheaper units, the Levoit Core series contains no ionizer functions and just relies on efficient fans with good-quality air filters. 

The Levoit Core Mini is still a โ€œCoreโ€ unit but is much smaller than any other air purifier in the series. I expected this unit would start a new trend for โ€œmini air purifiers,โ€ and I was right. Since the Core Mini was launched, various smaller units from other manufacturers have been released.

As with all the reviews we do here at HouseFresh, we bought the Levoit Core Mini with our own money to avoid any biases of accepting free goods in exchange for reviews. Our ultimate goal is to share the data and let you decide if this air purifier sounds like a good fit for you. If an air purifier sucks, we have no problem saying it. You can read about our methodology here.

The overall score for the Levoit Core Mini incorporates first-hand data results from our battery of tests, as well as our ratings for customer service, brand transparency and design & UX. Check out the full scorecard below to see the split of categories.

The pros and cons of the Levoit Core Mini

A summary of our top-level findings after testing this air purifier following our methodology.

“Unfortunately, the Core Mini wonโ€™t be powerful enough for rooms in your home and filter replacement costs will be high compared to other small units.

That said, this small air purifier can be a good option for travelers and to be used in small spaces like a car or an RV.”

CONS

With a CADR of 41 cfm, its air cleaning performance wonโ€™t be suitable for any space bigger 61 sq. ft., based on five air changes per hour.
Filter costs will quickly start to add up. It has higher filter costs than the Levoit Core 300S, but they must be replaced just as often.

PROS

It cleaned our test room of smoke pollutants in 136 minutes โ€” much better than more expensive models like the AROEVE MK01 (163 minutes) and the Briiv (291 minutes).
A very low power draw of 6.4 watts โ€” less than $10 of electricity cost per year to run continuously.
It is super small, so you could bring it along on trips as it can fit inside a backpack or suitcase.
It’s quieter than most, reaching 44.5 dBA at top speed.

Filtration technology

The Levoit Core Mini has a small, bonded cylindrical filter with Levoit’s signature 3-stage filtration.

You get a pre-filter mesh over a particle filter lined with a layer of activated carbon on the inside.

Levoit Core Mini Filter Close Up e1753287060464

The filter is very small, which means that they will need replacing more often than other units in Levoit’s Core series like the 300S or the 400S.

Levoit Core Mini Filter

Levoit used to advertise the filters in their Core series as True HEPA filters but discontinued the mentions of HEPA in their advertising after Dyson challenged their claim in front of the BBB National Programs National Advertising Division (NAD). This doesn’t change the fact that these filters work, but it is important to highlight that they are not HEPA-certified.

Design, controls and features

The Core Mini is a mini air purifier that you can hold with one hand.

Levoit Core Mini Living Room e1753287521262

It is the smallest unit in the Core range, weighing just 2.2 lbs and standing 10 inches high. It’s easy to carry around with you.

Levoit Core Mini Control Panel

The control panel sits at the top and it has four buttons, including three fan speeds and the power button. You also get a filter replacement indicator.

Levoit Core Mini VS Levoit Core 300S

It is much smaller than most models, including the Levoit Core 300S, which will be considered a small air purifier by most people.

Levoit Core Mini Essential Oils

One unexpected feature of the Levoit Core Mini is the ability to diffuse essential oils.

It’s good that you can use any essential oil you already use, so Levoit doesn’t force you to stick to a specific one.

While I donโ€™t believe many of the outrageous claims about the โ€œscienceโ€ of essential oils, it is a nice feature for an inexpensive air purifier that I imagine many people will be drawn to.

Air cleaning performance

The Core Mini needed 136 minutes to clean the air in our small 728 cubic feet test room, making it too underpowered for most rooms but a good alternative for an RV or campervan.

According to our PurpleAir Zen sensor, the Levoit Core Mini needed 136 minutes to achieve PM1 zero in our 728 cubic ft. test room. We estimate a PM1 CADR of 41 cfm, which would allow the Core Mini to provide five air changes per hour in spaces no larger than 61 sq. ft.

But this information in isolation wonโ€™t tell you much, so check out how this compares to other popular small air purifiers on the market today:

Levoit Core Mini Performance scaled

As you can see from the table, there is a reason why I always recommend our readers to buy the largest device they can live with. In simple terms, air purifiers are just a fan and a filter, so the bigger the fan and the bigger the filter, the better the performance.

In the case of the Core Mini, the $50 price tag might make it look very appealing but if you’re short on budget, I would recommend you to try and stretch to $75 to get a Winix A231 as it was able to complete our particle removal test in a third of the time it took the Core Mini.

Sound levels

In our testing, the sound levels of the Core Mini ranged from 37 dBA to 44.5 dBA.

Levoit Core Mini Sound Test

๐Ÿ’กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10

We used a sound level meter to measure how much noise our air purifiers generate at each fan speed.

At top speed, the Levoit Core Mini reaches 44.5 dBA. Check out the chart below to see how this compares to other similarly-priced air purifiers running at top speed:

But sound can be subjective so have a listen for yourself:

Long-term running costs

Running a Levoit Core Mini will cost you $81.96 per year, combining energy consumption costs and filter replacement prices.

As always, we used our energy meter to measure how much electricity the Core Mini uses when running at each fan speed and also while on standby. Energy consumption ranges from 1.2 watts on sleep mode to 6.4 watts when running at top speed.

This means that if you had to leave your 4 Pro running 24/7 at top speed, it would cost $7.11 in energy costs for a year, using average U.S. energy rates.

Considering you need to replace the filter every six months and that the replacement costs $24.99, you can expect to also spend $74.85 per year on filters.

When compared to other similar-performing air purifiers, the 4 Pro is generally cheaper to run, thanks to its low energy usage and low-cost OEM filters:

In comparison, you would be paying $60 for the Levoit Core 300S, cleaning much more air in the same period.

Bottom line: Should you buy a Levoit Core Mini?

With a dust CADR of 39 CFM, you won’t be able to use the Core Mini in a large space.

I like the Levoit Core Mini, but I do worry that itโ€™s likely not the best air purifier for everyone.

Itโ€™s too small for medium to large rooms, and the costs of filters will add up over time. But it costs less than $50, which equates to $0.7 per 1 CFM, which is okay for a unit of this size.

Levoit Core Mini Living Room

๐Ÿ’กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10

It is a good option for very small spaces like an RV or a car as itโ€™s portable and easy to find a space for.

But if you are looking for the best $ to performance, then the older Levoit Core 300 will give you much better performance and similar filter costs. And the Winix A231 will cost $25 more initially but will give you three times the air cleaning performance of the Core Mini.

ULTTY Fan and Air Purifier Combo CR021 review

ULTTY CR021 Combo Editorial no logo

When I took a deeper look into ULTTY, the company behind this air purifier/fan combo, there was not much information on their website. When I looked at archive.org, the first site went live on July 28th 2020, and in their ‘About’ page mentions a factory you can visit but that info was removed from the latest version of the site. Analyzing their website details further, DNS records show that the site was registered in China, which makes sense. 

ULTTY seems like a smaller version of Taotronics. They are both Chinese manufacturers selling units directly to American customers. They donโ€™t just sell fan and air purifier combos but also garden hoses and frying pans.

As a manufacturer who sells direct, they donโ€™t waste time on marketing, with their value proposition defined by their low cost and ability to manufacture new designs quickly. They currently have multiple types of air purifier/fan combo units, and also a fan/heater combo that sells very well. 

In the space of air purifier and fan combo units, we have one main player which is Dyson, and the next smaller competitor would be ULTTY. The main point of difference between ULTTY and the competition is the price: consumers can spend $150 to get a seemingly similar unit to a Dyson air purifier/fan combo, which costs at least $799. 

The unit we are reviewing today is the CR021, although now there is also a CR022 for sale which is slightly larger and more powerful. The ULTTY CR021 uses an H13 HEPA filter and can work as a fan and air purifier combo or just one without the other. 

All this to say, we didn’t just gather some features and specs from the manufacturer’s website and called it a day.

The lowdown on the ULTTY Bladeless Fan and Air Purifier Combo CR021

danny

“The ULTTY CR021 does the job but takes a long time, making it an okay option for really small spaces or for those of you who don’t need to clean the air quickly.”

โ€” Danny Ashton, Founder & Senior Writer

ULTTY CR021 Combo Editorial 2

Canโ€™t be bothered to read more? Then insert my key thoughts about this air purifier/fan combo straight into your brain below:

What we really like

The bladeless fan feels very sci-fi and futuristic.
It comes with an H13 HEPA filter, which is not normally used in cheaper air purifiers.
Simple remote that does everything you need.
Small size and lightweight, so easy to move around.
Price is much cheaper than big brand competitors.

What we think could be better

The lack of activated charcoal means it has no odor-removing ability.
Air cleaning performance is similar to a $70 air purifier.
No on-board sensor for indoor air pollution.
Cheaper build quality and design when compared with higher-priced models.

No Dyson, but still looks great

OK, so the ULTTY CR021 doesn’t look as sleek as the Dyson units, but considering its cost, itโ€™s not a bad looker.

It still has the bladeless fan of the Dyson, with the main body used as the location for the HEPA filters. The screen is simple, with 9 speeds available but no onboard particulate or VOC sensors.

When you compare it to the Dyson combo units, itโ€™s much shorter but has a similar floor footprint.

ULTTY CR021 Combo Comparrison

Unlike Dyson units that need an app to unlock all of their capabilities truly, the ULTTY keeps things simple with an old-school remote control.ย

With the remote, you can adjust the level of rotation, the fan speed, and also set night mode or timers. While an app would be nice, I would be worried that it wouldnโ€™t be built to the high standard we saw with the Dyson link app, so I am much happier with this simple approach to using this fan/air cleaner.

Filters wonโ€™t remove odors

The ULTTY CR021 comes with an H13 HEPA filter. This is the same medical-grade filter Dyson uses, but I think this was a mistake for such a low-powered fan.

Lower-grade HEPA filters can still remove many small particulate particles from the air and are usually a better fit for air purifiers with low-power fans.

ULTTY CR021 Combo Filter 2

The higher the grade of HEPA, the denser the fibers and the harder it is to push air through them. This was one of the reasons we saw such a high cleaning score for the Smart Air S even though it used H11.

ULTTY CR021 Combo Filter 1

The big downside about the type of filter ULTTY uses is that it has no activated charcoal – it doesnโ€™t even use the cheap impregnated type we see on lower-budget versions. This means that while the HEPA will remove particles, all odors will not be removed. This feels like a big home goal, as I know that most household users will want to remove odors. Thatโ€™s why we see activated charcoal used in budget air purifiers like the Levoit Core 300.

ULTTY CR021 Combo with filter

$149.99 AT amazon

The lack of activated charcoal is something that I really hope this manufacturer looks at for future versions, as right now, it has no odor-removing ability.

Changing the filter on the ULTTY CR021 is not difficult at all. Watch the video to find out how to do it:

This might seem silly, but do make sure you remove the filter from the plastic bag it arrives in. Every manufacturer will keep filters sealed so they are not used passively. If you don’t remove the plastic, the air will not be cleaned, and you might even cause overheating problems or melt the plastic. 

The ULTTY CR021 cleared our test room in 2 hours and 11 minutes 

As with all the reviews we perform here at HouseFresh, we went deep to see how well the ULTTY CR-021 is at removing pollutants from the air. 

ULTTY CR021 Combo Testing

We did this by performing the same test that all our air purifiers are put through to see how fast they clean one incense stickโ€™s worth of pollutants. As all our air purifiers are tested in the same room (a 728 cubic ft office), we can compare performance across all models and brands. 

We use a Purple Air indoor sensor to export the pollutant count every 2 minutes for PM1.0ug/m3, PM2.5ug/m3, and PM10.0ug/m3. As we also have a professional background in data analysis and information design, we like the visualize the data in an interactive chart for our readers to explore:

I knew this fan/air purifier combo wasnโ€™t going to beat records for cleaning particles from the air based on its price and reported CADR, but it was good to see that it did manage to remove all pollutants within 131 minutes. 

Air cleaning performance test results

In comparison, the Dyson HP04 air purifier and fan combo cleaned the air 47 faster than the ULTTY CR021, but this comes at a cost of nearly $900. Looking at pure air purifier performance, you will see that the ULTTY device is similar to the Levoit Core Mini with 113 minutes. However, this combo unit managed to clean the air quicker than the Aroeve MK01 which took 163 minutes with its pointless HEPA H13 filters.

Noise levels test results

The ULTTY has a maximum sound of 59 dB, less than the $360 Molekule Mini but more than the 44.5 dB we see with the Levoit Core mini. Itโ€™s a good unit for sound especially considering the function of a fan which is inherently noisier.

But feel free to listen to the actual noise levels in the video below to see if the sound would be a good fit for your ears:

The cost to run a ULTTY Bladeless Tower Fan and Air Purifier Combo CR021: $98.11 per year

Most people just look at the initial price of an air purifier, or as in this case, a fan/air purifier, but there are extra long-term costs you have to consider, with both electricity and filter costs needing to be considered. 

1. Electricity costs = $38.13

Energy costs are not getting cheaper and are doubtful to see any big drops in the next few years, so energy usage is now something that every homeowner needs to consider. There is no point in getting a gadget that uses so much electricity that it outweighs any benefit it provides. 

With a top wattage use of 25 watts, this air purifier/fan will not break the bank as even 24-hour usage will only cost $38.13 a year according to the U.S. average energy prices of the Bureau of Labour Statistics.

The fact that this does two jobs could be something to consider, as running both a fan and air purifier could cost much more than this.  Overall, itโ€™s an energy efficient machine for the price. 

2. Filter costs = $59.98

HEPA technology is remarkable โ€” just using fabric filters, you can remove tiny particles and viruses from the air. But the main downside is that these filters will need replacing over time if they are expected to keep cleaning air with the same performance. We based our calculations on filter replacement required every six months.

The genuine filters from the manufacturer cost $29.99, which might seem cheap, but considering it has no activated charcoal, is a little higher than I would want to pay. If you are open to generic filters, you can get them for under $15, which seems a fairer price considering the technology used. 

In comparison, you pay $70 for genuine Dyson air purifier replacement filters, which do contain activated charcoal, but you can see how these costs can start to add up. While not the cheapest filters, you can a 2-pack of generic filters for $39.39.

Bottom line: Should you get an ULTTY Combo CR021?

There are some major downsides to the ULTTY Bladeless Tower Fan and Air Purifier Combo CR021.

The lack of activated charcoal seems like something that could be fixed easily without a massive increase in price for filter replacements. As for the fan, I am as happy as I was with the Dyson โ€” having a bladeless fan is great for when you have kids as you donโ€™t have to worry about them poking it with their fingers.

If you like the idea of a fan and air purifier that doesnโ€™t cost the earth, then you donโ€™t have any other options currently than the ULTTY models. But if you are more worried about getting the best air cleaning bang for your buck, you would be better off with a cheap fan and a budget air purifier as you will get far more performance per $ spent. 

If you really want a combo fan + air purifier and have the money to spend, I would recommend the Dyson combo units as they look way better, have better performance, and have a ton of extra smart features with an app that is actually useful, but it does come at a cost that is closer to $1000.

Medify MA-14 review

Medify MA 14 Bathroom

Medify hasnโ€™t been making air purifiers as long as some; founded in 2017 in Deerfield Beach, Florida, USA, by an engineer set on helping reduce indoor air pollution. They now have a large range of units suitable for various room sizes to match your needs.

With this range of units, Medify has given itself an advantage over the competition. But, the focus isnโ€™t on variety; itโ€™s on the high-quality filters inside them, as they only use H13 or H14 HEPA filters in each model.

The โ€˜miniโ€™ air purifier market has grown significantly recently, with many brands offering units for smaller spaces. With so many models to choose from, like the Levoit Core Mini, the AROEVE MK01 and the notorious Molekule Air Mini, itโ€™s easy to see why finding the right one is essential. 

Weโ€™ve previously reviewed the larger MA-40 with its high CADR (Clean Air Delivery Rate), H13 HEPA filter and ionizer, and the MA-25 that outperformed other similarly priced units, so itโ€™ll be interesting to see how the smaller MA-14 performs.

Without further ado, this is what I learned after testing the Medify MA-14.

The lowdown on the Medift MA-14

danny

โ€œThe MA-14 is an okay unit when used in the right room. It would be ideal for taking on the road in your RV as it doesn’t take up much space and it’s quiet. But there are better air purifiers out there for the same price.โ€

โ€” Danny Ashton, Founder & Senior Writer

Medify MA

If you donโ€™t have time to read all the ins and outs of the MA-14, check out our โ€˜Too Long; Didnโ€™t Readโ€™ list of the main pros and cons of the unit.

What we really like

It’s nice and quiet.
Very easy to operate.
It’s light and effortless to move between rooms.
Comes with an H13 HEPA filter.

What we think could be better

I’d like to see them use activated carbon pellets in the filter.
Doesn’t have an air quality monitor.

Small, but surprisingly effective

For an air purifier of this size, youโ€™d expect it to have a reasonably low CADR as weโ€™ve seen in the Levoit Mini (32 CFM) or the Molekule Air Mini (estimated 25 CFM), but the MA-14 packs more of a punch with its CADR of 70 CFM which is closer to the $700 Dyson HP04 (89 CFM).

Looksโ€ฆlike a mini air purifier

Now that air purifiers have proved to be a โ€œmust-haveโ€ device in our homes, brands have to put a lot into the design of their units (see the Fร–RNUFTIG by IKEA, for example) to get our attention as customers. 

Medify MA 14 Kitchen

The MA-14 isnโ€™t breaking any molds with its design, but it still looks good (especially in black). My favorite feature is the stand attached to the bottom instead of the unit sitting flush to the floor, like MA-25.

Medify MA 14 Look

I like the look of the MA-14. Its curved lines and sunken grill give it a โ€œmodernโ€ feel, and the controls are right in front of you, making it very easy to use.

Small True HEPA H13 filter

The MA-14 has an ace up its sleeve by including a True HEPA H13 filter under the hood. It may be small, but we love seeing this grade filter used in home air purifiers. Also known as โ€œmedical grade,โ€ this type of HEPA can trap up to 99.9% of particles down to 0.1 microns.

Medify MA 14 Filter NO LOGO


If you donโ€™t know the difference between HEPA grades (aka you have a life), check out our handy chart or read our full guide here.

Variations of HEPA Filtration

Along with the HEPA is an in-built pre-filter and a layer of active carbon composite. The pre-filter is there to trap larger particles like dust in the air. These particles will settle on the surface of the pre-filter, which can be wiped off, prolonging the life of the HEPA.

Medify MA 14 Filter Top

Activated Carbon is used in many air purifier filters as it removes odors and other harmful VOCs (Volatile Organic Compounds) through adsorption*. Unfortunately, for this to be effective, the filter has to be packed with a large amount of activated carbon, which the MA-14 filter is not, making it more of a gesture than a solution.

Too much jargon? Donโ€™t worry; we have written an in-depth article that explains how an activated carbon filter works in easy-to-follow terms.

As with all HEPA filters, you must replace them periodically to keep them effective. Because the filter is small enough to fit inside the MA-14, itโ€™s recommended that you replace it every three-four months. Which, compared to other units, is fairly short.

Luckily, replacing the filter when the time comes is simple. All you need to do is follow these easy steps:

  1. Unplug the unit
  2. Turn it upside down and unscrew the cover clockwise to open
  3. Pull out the old filter and insert the new replacement
  4. Screw the cover counterclockwise to secure

Easy!

Medify MA 14 Filter Open Unit

Always remember to remove all the plastic wrapping before you insert a replacement filter into the unit. If you donโ€™t, the filter wonโ€™t be able to work and youโ€™ll probably cause a burning smell which, trust me, you donโ€™t want.

3 button control

Some of you out there will be searching for a unit with all the latest technology and gadgetry; well, sorry, keep looking. The MA-14 is a simple air purifier with a no-thrills approach. With only three buttons to operate, you canโ€™t get easier.

Medify MA 14 Control Buttons

There are four fan speeds to choose from:

1. Slow

2. Medium

3. Fast

S. Sleep

When you select Sleep, the fan will set to a slower than Slow speed and all the lights will automatically turn off after five seconds, so there are no distractions to keep you awake. To wake the unit back up, you need to press any button.

The Medify MA-14 cleared our test room in 77 minutesย 

When looking for the right air purifier for your space, you want to know how efficiently it removes pollutants from your room. That’s why one of the most important factors to remember is to buy a unit that can handle the size of your room.

Medify MA 14 Filter Unit

We recommend that the MA-14 be used in rooms around 109 sq ft to be effective, which may sound small for a living room or den but would be ideal in a small home office, bathroom or even in an RV.

We test each air purifier in the same conditions to compare the units we review like for like. We first fill our home lab (728 cubic ft) with incense smoke to see how fast each air purifier cleans the pollution generated by the smoke.

Medify MA 14 Testing

Once our room is thoroughly contaminated, we turn each unit on to its highest fan speed and measure how long it takes to remove all pollutants from the air. To monitor this process, we use the Purple Air indoor sensor, which updates the PM1.0ug/m3, PM2.5ug/m3 and PM10.0ug/m3 levels in the room at regular intervals. 

Once the test is complete, we compile all the data onto a graph to see how it performed.

As the MA-14 has a CADR of 70 CFM, we expected it to have a comparable result to the Fร–RNUFTIG from IKEA, which has the same CADR and we werenโ€™t expecting anything under 60 minutes as it was a big space for a small unit.

Hereโ€™s what we found with the Medify MA-14.

Air cleaning performance test results

The graph shows us that from the peak of contamination, it took the MA-14 77 minutes to clear all that smokey pollution from our testing room. There was no swift decline in the graph like we see from more powerful units, but it cleared the air consistently.

The Fร–RNUFTIG completed the same test in 65 minutes with the same CADR. Itโ€™s also less expensive and looks better. What gives IKEA the cleaning power over this Medify is the size of its fan compared to the smaller one inside the MA-14.

Noise levels test results

A great feature of the Medify MA-14 is the sound it produces. You wouldnโ€™t expect a unit of this size to produce a lot of noise, but sometimes these little units surprise you (like the Molekule Mini, for example). 

Luckily the MA-14 produces from 21dB on low to 48dB on high, which is about the same level as average room noise. Listen to this sound video, where I run through each fan speed.  

The cost to run a Medify MA-14: $111.05 per year

1. Electricity costs = $37.06

Nothing can be said to be certain in this world except death, taxes and rising energy costs. Hence, itโ€™s important to look at how much energy an air purifier uses to determine how much it will cost you to run per year.

Luckily, brands are energy conscious and do their best to make their products as efficient as possible. Not only does this save your wallet, but it also saves the planet as more energy = more pollution, which = more air purifiers, which = more energy and so on.

We used the average energy prices as reported by the U.S. Bureau of Labor Statistics to determine how much an air purifier will cost to run in your home. We estimate that the annual cost of running the MA-14 would be around $37.06 as we measured it to pull 24.3 watts of electricity from our socket. If we compare this again to the Fร–RNUFTIG, which only pulls 14.7 watts when running at top speed ($22.42 per year). IKEA’s unit not only clears our room faster and costs less to run each year.

2. Filter costs = $73.99

Another cost you need to consider when buying an air purifier is the price of replacement filters.

HEPA filters may be the most effective way to clear contaminants from your room, but it comes at a cost. HEPA filters work by trapping particles in their intricate maze of glass fibers, and over time, those fibers fill up and become less effective. Think of it like a spider web catching flies; there is no spider to clean up.

You should change the filters on the MA-14 every three to four months. The reason is that they are much smaller than most filters, so they fill up faster, meaning the cost to run is higher than other units with larger filters.

Once youโ€™ve used the filter it comes with, you should (if used in the correct sized room) be able to get away with buying a 2-pack of filters each year. If you go for the official Medify filters, a twin pack will set you back $73.99 on Amazon. Unofficial filters are cheaper, but we canโ€™t vouch for them as we havenโ€™t tested them.

Bottom line

Medify is a big player in the air purification game, and with units like the MA-40 and the MA-25, itโ€™s easy to see why. But the MA-14 seems to fall short for me. I would be as brazen as to say that the whole of the “mini air purifier” market falls short.

As a mini-unit, the MA-14 is better than most; it has a much higher CADR than others and outperformed the Levoit Core Mini in our home performance tests. But, when you compare it to other units you could buy in the same price bracket, like the Fร–RNUFTIG from IKEA or even the powerful AP003 from Taotronics, you could get so much more for your money.

Medify MA 14 Bathroom

The Medify MA-14 does have strengths. If the size is a factor, for example, youโ€™re looking for an RV, bathroom, or small home office air purifier, the MA-14 will sit neatly on a desk or the floor in a corner and not take up too much room. Itโ€™s also very quiet, so it wonโ€™t distract you from whatever youโ€™re doing.

The best part of this unit is that Medify has equipped it with an H13 HEPA filter, which has given it the edge over the competition. But with the lack of smart features and a small fan, thatโ€™s all the MA-14 has to offer.

Dyson PH03 Air Purifier and Humidifier Review

Dyson PH03 Living Room

Dyson was founded in England in 1991, and it has quickly grown to become a powerful brand with over $6.63 billion in revenue and 14,000 employees around the world. They are famous for their bagless cyclonic vacuum cleaner, conceived by founder and inventor James Dyson after he became frustrated with his Hoover vacuum continuously clogging.

Since then, Dyson has been regularly introducing their latest inventions to many different categories of household appliances – and the Dyson PH03 is no exception. The “Air Multiplier” was Dysonโ€™s approach to a fan with no blades. Since then, there have been multiple upgrades to this bladeless fan, such as the Dyson HP04 that included a fan, an air purifier and a heater. The Dyson PH03 is a combination of a bladeless fan, humidifier and air purifier. 

In the current market, there is nothing quite like this unit. Whilst there are a handful of humidifiers with air purifiers, there are no units that can also work as a bladeless fan. This new technology doesnโ€™t come cheap, however, as this particular unit is sold on average for $819.99, which is the same price range as the IQAir Healthpro Plus.

One thing I really dislike about Dyson is that they donโ€™t reveal the CADR score for their air purifiers. They suggest that itโ€™s unfair to their units, which have a different way of cleaning the air, but I think they want to keep consumers in the dark. 

When I reviewed the Dyson HP04, I was able to find the CADR score (169.6 m3/h or 88 CFM) on the Chinese website, as they have strict rules when selling in PRC. Thanks to Google Translate, I could get both the gaseous and particulate scores for the Dyson PH03:

Dyson PH03 Chinese CADR report

When we convert this to CFM we have a particulate CADR score of 99.8 CFM, which is higher than the HP04 but is the same level of cleaning performance as the Blueair Blue Pure 411 which has 120 CFM but costs $110.

Manufacturers have been known to fib about CADR scores and while I donโ€™t think Dyson would lie to the Chinese government, we want to know how well this air purifier can clean air in a real-world situation. That is why we tested this unit in our own home test lab.

The lowdown on the Dyson PH03 Air Purifier and Humidifier Combo Unit

Danny Ashton HouseFresh
โ€œA premium combination unit that includes a humidifier, fan and air purifier. The design, intelligent features and app are world-class but the Dyson PH03 has the same cleaning power of a $100 air purifier with a much higher price tag.โ€
โ€” Danny Ashton, HouseFresh Founder & Senior Writer

Dyson PH03 Living Room

PRICE on amazon PRICE on DYSON

If you donโ€™t fancy reading my 3000+ word review (how dare you!) then here are my key findings:

This is a fairly low-powered air purifier that can operate as a humidifier and provide cooling through an oscillating fan. It is currently the only appliance available in the world that can do this.

What we really like

Best air cleaning performance for a combo unit we have tested
Impressive to get humidifier, fan and air purifier in one unit
Pure HEPA, activated charcoal, and no ionizer, which means zero ozone is created
Design is off the charts in product design and the remote control. The Apple of the air purifier market
The app is a real game changer in this industry with a great UX

What we think could be better

High initial price and you can’t control the unit from the onboard buttons – need remote or app
Pure air cleaning performance is better with the $99 Levoit Core 300
The latest filter uses impregnated filters rather than separate charcoal pellets, which feels like a step down in performance

Mediocre air cleaning power

At nearly $900 the amount of cleaning power is similar to an air purifier in the $100 range, but this unit does have the functionality of a humidifier and a fan, so itโ€™s not a totally fair comparison. 

It is, however, something to consider if you are primarily looking for a gadget to clean your home air.

The Dyson PH03 looks like $900!

If we were hosting a beauty competition, the Dyson PH03 would win hands down. When we finish testing our units, I have no problems finding a home for these Dyson units and I donโ€™t think this is just because my family wants to sell them on eBay. 

Dyson PH03 Living Room

They look great, and you can easily see them adding to your home decor – air purifiers used to be beige units that looked more like photocopier machines than something you would want in your living room.

If you have a Dyson vacuum cleaner and you’re honest with yourself, you like it for its design as much as its ability to clean – and youโ€™re happy to pay a premium for this.

Dyson PH03 Back

The first thing I noticed that was different with the Dyson PH03 compared to the HP04 that we had tested previously, was the quality of the screen. Itโ€™s like a miniature monitor that has full color and can show little animations on how to remove filters or fix something rather than just showing an error code.

Dyson PH03 Screen

This screen also shows the exact level of pollutants to the nearest ug/m3, as well as a color code from green to purple. The additional VOC sensor is something you never see on an air purifier and whilst it takes a little longer to give a reading, itโ€™s good to see that in the future this might roll out to more affordable units.

Dyson PH03 Screen 2

As soon as I took this air purifier/humidifier combo out of the box, I noticed how much chunkier it was than the HP04.

Dyson PH03 Comparison

This makes sense considering it has a water reservoir with a cleaning function. Unlike the HP04, the whole unit doesnโ€™t move to provide oscillation. Instead, small slits on each side adjust the fan flow.

Dyson PH03 Water Tray

Adding a water reservoir could be problematic if the whole base unit rotated, so it makes sense that they have adjusted this feature. However, it does mean that the unit has a maxim oscillation of 90 degrees versus the 350 degrees you get with the Dyson HP04.

The same filter as other Dyson Combo Units

The HEPA filter used with this unit is rated as HEPA H13, and it also contains activated charcoal. When looking at the filter, you can see that the activated charcoal is impregnated into the HEPA filter, so this unit doesn’t come with a separate filter filled with activated charcoal pellets you often see in other air purifiers.

Dyson PH03 HEPA

Impregnated charcoal will still work, but it is not as effective as using large pellets, which you often see in higher-end units or even the budget Taotronics AP-003 we tested recently. 

When comparing the filter size with the HP04, it seems that Dyson has decided to make a few changes. While the HP04 has a separate activated charcoal filter with pellets, the newer model has an integrated system with the charcoal filter being a part of the HEPA.

Dyson PH03 Filter Unit

With activated charcoal, more surface area means more cleaning power for odors and VOCs, so this update to the filter seems like a step back for those looking for odor-cleaning power. I would prefer a separate charcoal filter vs a combination like we see with the PH03.

Dyson PH03 Filter

As with the HP04, the PH03 filter looks well-made, and the seals do a good job of ensuring no air can bypass the filter. The prefilters make removing the lint and dust that will build up over time easy. 

The Dyson approach to customer information is top-notch, with very clear labels that no one could miss, informing them to remove the plastic from the filter before using the unit.

The Dyson best in class app

The Dyson PH03 has only 2 buttons on the unit itself – a power-on button and a cleaning mode to clean the humidifier unit.

Dyson PH03 Controls

Handily, you also receive a remote control that is highly intuitive. As I first saw with the HP04, it sticks to the top of the unit magnetically – very cool.

Dyson PH03 Remote 2

The remote is small, light, and simple to use without referencing the manual. You can adjust the humidification, fan speed, and oscillation – and even request current pollutant levels from the onboard screen!

Dyson PH03 Remote 2 NO LOGO1

Similar to Apple TV, the Dyson remote control nearly makes you forget that you’re paying $900 for $100 air cleaning power as it just feels good to use.

PH03 MyDyson App setup

I got to test the Android App and similar to my experience with the Dyson PH03, the experience was sublime.If you have read any of my other air purifier reviews, you will know I am not normally a fan of apps, as most are usually poorly made and donโ€™t have any real value.

If only all air purifiers had an App like MyDyson, then it would be worth paying more for app-supported features. Pairing my unit took less than 10 seconds and only required me to enter my home Wi-Fi password.

MyDyson PH03 Setup and Ready

The app was ready to go within one minute. What I like the most is that the app gives me all the abilities of the remote as well as continuous updates on air quality for both particulates and VOCs. I could even receive air quality details for my local area.

Using the app, I could also easily switch between both machines I have in the house – if you love technology, then you will also love the MyDyson app. Donโ€™t just take my word for it; the app has 4.1 stars on Google Play (over 1M downloads) and 4.5 stars on Apple across 7.6K ratings.

The Dyson PH03 cleared our test room in 1 hour and 10 minutes

I love the look and smart features of the Dyson PH03, but letโ€™s get to the core issue: how well it cleans the air in our home. 

Many air purifier reviews you will read wonโ€™t put effort into finding out how well an air purifier cleans the air in the room, so we have made this our main focus here at HouseFresh. Painting the real picture is especially important with brands like Dyson, who donโ€™t share their CADR scores outside of China. We hope our reviews will inform consumers who are about to get caught up in jargon and marketing speak without knowing how well the unit they are about to buy does the job it was designed to do. 

Our testing process at HouseFresh is simple. We use the same room with all the air purifiers we test (728 cubic feet), the same size as an average small bedroom or office. We then create indoor pollution using an incense stick before putting the air purifier on full power and tracking how quickly it can bring the particulate matter down to zero. 

For testing, we use the Purple Air indoor sensor, which provides regular updates of the level of PM1.0ug/m3, PM2.5ug/m3, and PM10.0ug/m3 at regular intervals. With this information, we can visualize the room cleaning and reach a number we can compare with other air purifiers from different brands. 

Based on the CADR data from the Chinese store, we would expect this unit to be on par with the Blueair Blue Pure 411 or Levoit Core 200S – and it should be slightly quicker than the Dyson HP04.

So, enough about our processโ€ฆ How did the Dyson PH03 do? Have a look below at the results:

Hereโ€™s how it did:

  • It took 70 minutes to remove all particulate pollutants from the air in our test room lab.
  • This matched up with the CADR scores we saw in China: quicker than the Dyson HP04 which managed 84 minutes.
  • The Blue Pure 411 was quicker at 68 minutes which makes sense considering its CADR was 120 CFM vs 99.8 CFM.
  • Compared to the air purifiers we tested, the PH03 is at the lower end but is still much better than the Honeywell Air Genius 5 HFD320 (93 minutes) and the Germguardian AC4825e (104 minutes).

Air cleaning performance test results 

When you compare the cost to CADR score, itโ€™s one of the most expensive units, although it is still better than the Aroeve MK01.

โ„น๏ธ Fact: While itโ€™s not the most powerful air cleaning, the Dyson PH03 is currently the best combo unit we have tested.

Noise levels test results

Sound-wise, the Dyson PH03 is not overly quiet, but at its highest, it doesnโ€™t hit more than 54.3 dB. This is less than the IQAir Healthpro Plus (61.2 dB), but higher than what we saw from the Alen BreatheSmart Flex (51 dB.) Some of this will be because this unit also works as a fan, naturally louder than just a pure air purifier.

But sounds can be super subjective, so feel free to listen to the different speeds in our video below:

The cost to run a Dyson PH03: $93.6 per year

1. Electricity costs = $63.60

A cost that many consumers forget when looking at air purifiers is the amount of electricity required to run it in the long term. If you have a continuous issue with outdoor pollution, you will likely use your air purifier 24 hours per day – electricity costs can add up with power-hungry units. 

Luckily, the Dyson PH03 is efficient, especially considering it does three jobs in one. When we tested it at its highest speed, it only pulled 41.7 watts which is much better than units with less cleaning power, such as the GermGuardian AC4825e that pulled 44.25 watts on full power. 

This level of energy consumption would cost you around $63.60 per year, according to the average energy prices in the U.S. as reported by the Bureu of Labour Statistics.

2. Filter costs = $30

Filter costs are another thing that air purifier customers can forget, and they can add up over time. HEPA and activated charcoal are mechanical filtration technology, which means that they will need to be replaced over time as pollutants get lodged in the filter. 

Dyson says that the filters will need replacing every 12 months, which is better than many smaller units that need to be replaced every 6 months. For reference, the genuine filters cost $79.99 each. This is on the higher end, as the filters for most units with this cleaning power cost less than $50 on average. 

However, this wonโ€™t be too bad if they only need replacing every 12 months. I will update this review to see how long we can get with our current filters. 

You should also be aware that non-genuine filters exist for this air purifier, with a pack of 2 available for $59.99. A cost of $30 per filter is a lot more palatable. While genuine filters are priced higher than the competition, the availability of generic filters means long-term costs should align with other units with this cleaning power.

Bottom Line

This is normally an easy section to write up, with most air purifiers falling into the โ€˜goodโ€™ or โ€˜badโ€™ camps. However, itโ€™s much trickier with the Dyson PH03 humidifier, fan and air purifier combo. 

Just looking at pure value for air cleaning power, it could seem that you are seriously overpaying with the Dyson PH03. But, this unit has a ton of extra features, its design is attractive, and it comes with top-end smart features that are unique across the whole air purifier industry.

Like Apple, Dyson has made design a key focus with these gadgets. For those people happy to pay the โ€œDyson taxโ€ you will be pleased with a great fan humidifier combo that can also keep your bedroom air clean of particles, VOCs and gasses. It truly feels like an Apple device with the tech.

If you want to get the best bang for your cleaning buck, you are much better off investing in the reigning best budget air purifier in our rankings, which is less than $100 and has twice the cleaning power of this Dyson fan and humidifier combo. Be sure to check out the latest air purifier prime day deals and Black Friday air purifier deals, as often, the Dyson units have some of the biggest discounts during these sales.

Dyson PH03 Close Up

I donโ€™t think this unit is aimed at these customers. Dyson, as it does with all its appliances, is promoting high-end units that are 100% focused on the customer experience – from the design of the unit, the use of the remote, the weight of the remote, and all the smart app-supported features. 

They offer a two-year warranty and if you have ever had other Dyson gadgets, you will know they do everything in their power to keep you happy if anything goes wrong.

The reality is that there is no other gadget on the market that does everything the Dyson PH03 can do, so it makes sense that the team at Dyson is charging a premium for it. 

If you are happy to pay a premium for a โ€œDysonโ€ and need a unit capable of humidification with an oscillating fan and an air purifier suitable for a small to medium-sized bedroom, this is the unit you should go for. 

If itโ€™s just the air cleaning power you are after, there are much better air purifiers that perform just as well, but you will give up the technology and design that the Dyson unit brings. 

Most people should pass on this unit, but I am pleased to see the improvements in cleaning power and features as Dyson keeps innovating in this sector. I hope they stick around to develop more units like this.

But which Dyson model is the best?

I find it strange that Dyson has many air purifier combo unit variations. For example, for the humidifier, fan, and air purifier range, you have:

– Dyson Pure PH04
– Dyson Pure PH03 
– Dyson Pure PH3A
– Dyson PH02
– Dyson PH01

The first thing to note is that all the above units use the same filter system, so the HEPA filter and activated charcoal setup is the same for all models. There is also an additional Cryptomic layer featured in the Dyson PH04 and PH02 aimed at removing Formaldehyde. 

The PH3A is similar to the PH03 but doesnโ€™t come with any app support or Cryptomic layer and is slightly cheaper. The app support is my favorite part of this unit, so I donโ€™t think itโ€™s a good trade. 

To buy direct from Dyson, you must buy the latest model number. However, if you shop elsewhere, you might find older models with essentially the same features but for a much better price. Keep an eye out for that if you want to save a little money.

At HouseFresh, we have been reviewing air quality products since 2010. In all these years, we learned not to rely on manufacturers’ claims and the ever-so-glowing marketing materials. That is why we buy products with our own money, so we can write unbiased reviews after we’ve had enough time to evaluate air quality products in our home lab. Every unit we recommend has been thoroughly tested to assess its performance, energy consumption, and noise levels emitted in real-life environments.
