The COVID-19 pandemic fundamentally changed how we operated as a society. The โnew normal,โ a concept coined in 2008 after the financial crisis but then promptly forgotten, made a jarring comeback.
Fast-forward to 2024, a few years after the worst of the pandemic, and things seem to have returned to the โold normal.โ But still, itโs crucial not to become complacent. According to the CDC, 123.5 out of 100,000 people in the U.S. still get hospitalized for COVID-19, which means taking care of your air quality to prevent the spread of viruses and pathogens remains essential.
But you may remember that there was a time when we werenโt sure how exactly SARS-CoV-2 spread. It wasnโt only until May 2021 that the CDC updated its guidance and acknowledged the virus was airborne. The World Health Organization then corroborated that in December 2021 and has updated their definition to โthrough the air transmissionโ in April 2024.
All this (finally) leads us to the pressing question: Do HEPA filters really remove airborne viruses? Letโs examine how they work to see what they can do for the regular consumer.
What HEPA filtration science says about virus removal
HEPA (high-efficiency particulate air) filters are pleated sheets of the thinnest fibers intertwined to form a maze. According to the Environmental Protection Agency, HEPA filters can remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (ยตm).
But this doesnโt mean that it only works on particles this size.
HEPA grades are given for particles of 0.3 microns because these are the most penetrating size and the hardest to deal with by a filter.
In fact, HEPA filters can pick up smaller particles more easily. This is because the virus particles are pushed around by gas particles, increasing the chance of colliding with the filter fibers.
Viruses range from 0.02 to 0.5 microns. Influenza (the common flu) and SARS-CoV-2, for example, are approximately 0.1 microns. This means virus-size particles can easily be removed with HEPA-grade filters.
There have also been several studies that look directly at how well air filters work at removing COVID-19 virus particles.
Research carried out on coronavirus wards at Addenbrooke’s Hospital suggests that air filter machines removed almost all traces of airborne COVID-19 virus. To corroborate that research, a Japanese study showed that filtration using HEPA filters can consistently remove infectious SARS-CoV-2 from the air.
Bottom line: HEPA filters can effectively deal with airborne viruses.
Thereโs a lot of scientific research on how activated carbon filters can remove viruses and bacteria from water. Unfortunately, outside of the water, activated carbon filters can only adsorb gasses in the air, so they wonโt do anything for airborne virus particles.
Five tips for using an air purifier when youโre sick
Research has told us that air purifiers are effective tools for fighting off viruses. If itโs within your budget, you might want to consider investing in one to help ensure you keep a healthy home environment.
Here are some things to consider when using an air purifier to stave off sickness.
Tip #1: Make sure the air purifier has the right CADR for your room size
CADR (or clean air delivery rate) is how air purifiers are rated based on their particle removal performance.
A small air purifier will be too weak for a huge space, so you will want to choose one with a CADR high enough to provide at least 4.8 air changes per hour (or ACH).
As a rule of thumb, choose large air purifiers for large rooms, and be wary of tiny devices, as they are unlikely to provide enough air changes per hour in even the smallest of rooms.
Be aware that each room of your house will need an air purifier, so look for the right size for each room you want to keep clean.
Tip
We created a CADR calculator to make this easy to quickly figure out what is the right CADR for a specific room.
Tip #2: Run the air purifier 24/7
According to Faye McNeill of Columbia University, air purifiers’ auto modes arenโt adequate when trying to filter out airborne viruses or pathogens. Instead, you should run your air purifier at its strongest setting 24/7 while you or anybody in your household is sick to maximize the filtration of pollution and pathogens.
Tip #3: Place the unit strategically
If you live in a small apartment and have a very large air purifier that can cover it entirely, you wonโt have to worry about this too much. If not, experts suggest placing the air purifier three feet away from the person who is sick. Make sure there are no objects or walls blocking airflow.
Tip #4: Keep your pre-filter clean
Many air purifiers include a pre-filter used to catch large particles. Unless you clean it regularly, a dirty pre-filter can reduce the effectiveness of your device by up to 40%.
Through our own tests, we confirmed that dirty pre-filters can impact performance. So, we recommend purchasing air purifiers with a removable pre-filter to make it easier and healthier for you to vacuum and wipe them (or rinse them if itโs a washable pre-filter) every few weeks.
Tip #4: Change the filters periodically
HEPA filters become more effective at capturing particles over time, but all the trapped particles eventually clog the filter, making it more difficult for air to pass through it.
That is why it is important to replace your HEPA filter periodically.
Many air purifiers have in-built systems that notify you when the filter needs to be replaced. However, as a general rule, you should assess whether you need to replace your filters every six months.
When replacing a dirty HEPA filter after sickness, wear protective gear (face mask, goggles, gloves) and place the used filter in a disposal bag. This is also a good moment to give your air purifier a disinfecting scrub.
Yes, HEPA filters will help remove viruses from your air
The tiny particles associated with viruses like COVID-19 and influenza are so small that our bodies naturally canโt block them.
To maximize your protection when someone is sick in your home, you should still consider minimizing contact with that person (although we know that might not be at all possible in some cases) and ventilating your house.
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.
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 donโt 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 Okaysouโs Cayman 608 (which looks A LOT like the Levoit Core 400S) and Apollo 718 (a copy of Levoit Vital 100).
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 โliquidationโ bankruptcy. Liquidation, Chapter 7 of the Bankruptcy Code, means selling the companyโs assets to pay off its debts.
In December 2023, they achieved it: the court decided to convert the case to Chapter 7. Okaysouโs website is currently down, and thereโs no official Okaysou store on Amazon, either. The company’s prospects donโt 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.
The lowdown on the Okaysou AirMax 10L Pro
โThe Okaysou AirMax 10L Pro fails to meet the hype of its marketing and didnโt impress us in our real world air cleaning test and electricity usage.โ
โ Danny Ashton, HouseFresh Founder & Senior Writer
Itโs 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:
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:
When looking at the Okaysou AirMax 10L Pro profile, you can see that itโs reminiscent of the air purifiers designed by Alen:
As you can see, itโs 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:
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.
You donโt get fancy touchscreens with the Okaysou AirMax 10L. Instead, you have four buttons that do everything.
โ5-in-1 Purification Systemโ that doesnโt 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 โequipped with 5-in-1 purification system, washable dual-filter, nanois-Fflter, and honeycomb activated carbon filterโ.
Based on the image and the description above, I was expecting a sizeable pre-filter, two HEPE Filters, one โblue nanois filterโ, and an activated carbon filter. I kept looking inside the box because all I received was the following:
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 โAdvanced 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:
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:
The diagram above makes it clear that the nanois filter and the โpremium 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:
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:
When it comes to the filtration technology in the Okaysou AirMax 10L Pro, the unit comes with a unique filter called โAdvanced Blue Nanois Filterโ. It is a HEPA filter treated with silver ions, which are bioactive agents that can kill bacteria, viruses and other microorganisms.
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.
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 wonโt 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.
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.
The Okaysou AirMax 10L Pro is an overly-marketed product that doesnโt live up to the hype
In my opinion, Okaysou contacted us many times because they wanted us to write an overly optimistic review. Itโs clear that they are experts in marketing, but the AirMax 10L is not an air purifier I would recommend.
While itโs pretty cheap, $199.99-$149.99, you still get better air cleaning performance with the $99 Levoit Core 300.
I donโt 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 itโs a regular occurrence that a new brand comes to market with many promises and a price that is easy to digest.
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 doesnโt bend the truth to sell more units.
SOURCES
We calculated yearly costs associated with running the Okaysou AirMax 10L Pro 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.
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.
When you buy an air purifier, itโs not just the initial cost of the unit you need to consider. The filters inside the unit need to be replaced periodically for the unit to clean the air effectively.
But, instead of spending money (not to mention the waste) on new filters every time they become ineffective, canโt we simply clean and reuse them?
Over time, the activated carbon air filter becomes saturated as more contaminants get stuck to the carbon, reducing its ability to remove odors and harmful gasses. Itโs always recommended that you replace your carbon filter with a new one.
But does that mean you canโt wash and reuse them?
1.Carbon filters absorb water โ As carbon filters soak up water, it can take some time for them to dry out. If they are not completely dry (and quickly) when reinstalled, you risk mold growing. 2. May not remove all contaminants โ Washing carbon filters will get rid of any dust that is sitting on the surface. Still, there is no evidence to suggest whether it will remove any VOCs that have been adsorbed onto the carbon.
5-step guide on how to clean an activated carbon air filter
In most cases, we recommend replacing your used activated carbon filter with a brand-new one periodically. Many air purifiers will alert you when a fresh filter is needed.
Now, if this is not possible, then you should follow these five steps to clean your activated carbon filter.
Step 1: Turn off and unplug the purifier
Step 2: Remove the filter from your device
Step 3: Shake the filter to remove any accumulated dust
Tip
A vacuum cleaner will help remove any surface dust or dirt lodged in the filter.
Step 4: Wash the filter using warm running water
Tip
Use a dime-sized amount of liquid detergent and a sponge to scrub the filter gently and circularly.
Step 5: Leave to air dry before reassembling
โ ๏ธ As activated charcoal soaks up water, to avoid it being damaged by dampness and/or mold you must ensure the filter is completely dry before returning it to your air purifier.
Tip
As youโre already washing your activated carbon filter, this is the perfect time to clean the rest of your air purifier to ensure it runs effectively and efficiently. Check out our guide on how to clean an air purifier to learn how.
Making charcoal starts when a chemical reaction is introduced to a particular material, such as coal, wood, willow peat or bamboo. Much like when a fire goes out and leaves burnt wood behind, the charred remains formed from the chemical reaction is known as charcoal or carbon.
The activation process is when carbon is injected with hot air, carbon dioxide or steam to increase its surface area. With a larger surface area, the activated carbon can now capture more harmful molecules using absorption.
This means that pollutants such as odors and other VOCs (Volatile Organic Compounds) stick to the surface of the charcoal.
Because activated carbon effectively removes pollutants from the air, it is the perfect ingredient for an air purifier filter. Filter manufacturers use carbon in two forms for air purifiers: loose-fill carbon or a bonded carbon sheet.
Our research found that the filters containing loose-fill activated carbon are more effective at removing contaminants from the air than bonded sheet filters. The basic rule of thumb is the the more activated carbon a filter has, the more effective it is.
Through our performance testing, weโve found that filters that contain high levels of loose-fill carbon are more effective at removing harmful gasses than air purifiers that use bonded carbon sheets.
Here are our recommendations for air purifiers with high-performing activated carbon filters for various needs and room sizes.
Running an air purifier with a packed activated carbon filter is one of the most effective ways of removing odors and other VOCs from the air in your home. But their effectiveness lowers over time as they adsorb more harmful gasses.
Itโs highly recommended that, when your carbon filter is full, you buy and install a replacement.
You can, if you want, clean the filter, but be careful, follow our guide and make sure the filter is fully dry before you re-install it into your air purifier.
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 isnโt 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 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
โI love the look of the Levoit EverestAir and was pleasantly surprised at how well it did in our performance tests. Itโs 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.
The Levoit EverestAir broke the mold Levoit has gotten us used to, taking some inspiration from modern consumer electronics.
๐กexclusive 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, youโll quickly grow bored of the same white, boxy look with rounded edges.
But thatโs not what the EverestAir is all aboutโฆ
When looking at the unit from the front, I immediately got Blast Mini vibes:
But all that changes the moment you turn the unit around and find a sleek silver back panel:
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:
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:
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:
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 itโs time to replace the filter) and also air quality information (PM1, PM2.5 and PM10 particles in the air).
Thatโs 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.
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:
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. ๐๐๐
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:
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.
This large filter can deal with both pollutants and smells:
One side of this filter features a high-quality main filter to tackle the tiniest airborne particles:
The other side features a honeycomb 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 purifierโs filter, so it is great to see such a large quantity of activated carbon pellets included in the EverestAirโs 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:
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 wonโt 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.
๐กexclusive 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 couldnโt 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.
Donโt 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 itโs 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 donโt get the genuine ones from Levoit, bringing costs down to nearly $65.98 per year.
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.

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.
Itโs an easy air purifier to live with, but it doesnโt 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.
Whether you live in an apartment building or a condo, the smell of weed creeping into your own home can really impact your quality of life. The good news is that there are plenty of effective ways to eliminate the odor.
If youโre sensitive to weed smoke or just donโt like it, follow the steps below to lessen the problem.
1. Chat with your neighbors
It might be that your neighbors arenโt even aware the smoke is traveling into your home. So, first and foremost, talk to them and let them know that itโs causing you a problem.
Speak to them politely and kindly โ thereโs more chance the issue can be resolved amicably. For example, suggest to them that they might smoke in a different room or use an air purifier.
Anti-smoking laws can vary nationwide and recreational marijuana smoking is legal in states such as Oregon and Washington. This means that if you live in one of these states, you could suggest that your neighbor smokes on a back porch or backyard.
2. Open the windows
Ventilation is crucial when it comes to removing weed smoke. Opening windows (and doors) can help to air out your home and mitigate the smell.
Tip
If you have a fan, you could also create a cross-breeze by sticking one in the window โ facing outwards โ to help recirculate the air and freshen up your home.
3. Use natural odor absorbers
There are lots of essential store-cupboard items that can absorb and reduce smoke odors. Place small bowls of baking soda, coffee grinds, or vinegar around your place to help soak up the weed smell.
Tip
You can try using an activated charcoal bag as it has proven to be effective at eliminating pesky odors. You can even try to make your own, following our step-by-step guide to making a charcoal air purifier bag.
4. Try air fresheners
Air fresheners (sprays or plug-ins) are an excellent choice to offset the smell quickly. Just be aware, however, that these wonโt eradicate the odor (or the smoke!) but will only mask it for a time.
5. Use essential oils
As with the above, essential oils can effectively mask the smell of weed and help make your home smell fresh. You could place some drops in a bowl or use an oil diffuser. Another option is to use scented candles.
Tip
The following essential oils are well known for masking unwanted smells:
๐ Lemon ๐ฟ Eucalyptus ๐ฑ Tea tree oil
6. Cover your electrical outlets
Electrical outlets can be one of the main ways weed smoke infiltrates your home: when your neighbor smokes weed, part of it goes through their outlets and comes out through those in your own place.
Ensure all your sockets are covered with plugs or outlet seals to help prevent the smoke from getting into your space.
7. Seal gaps with weather stripping
Weed smoke can easily travel between apartments through windows, particularly if your neighbor smokes marijuana on a balcony or patio. Using weather stripping to fill gaps in your window frames will help block the weed smell from coming into your home.
8. Use a door sweep or thick towel to seal gaps beneath your door
Like windows, smoke can also travel between apartments by sneaking in under the doors. Fitting a rubber door sweep between your hallway door and the floor will help block the smoke from traveling to your home.
Tip
Alternatively, simply roll a damp, thick towel to cover the gap under your door.
9. Consider an air purifier with a powerful carbon filter
Air purifiers are great for removing all sorts of pollutants from indoor air, including weed smoke particles. Itโs best to go for a device with a high-quality HEPA filter AND a solid activated carbon filter – you will need both types of filtration in order to remove weed smell as well as smoke pollutants.
Tip
Pay attention to the CADR (Clean Air Delivery Rate), as this lets you know how much air the device will clean per minute. The higher the rate, the more effective itโll be.ย
Not sure which air purifier to get? Weโve put over 40 air purifiers through our rigorous testing process in the last year alone. These are our top three picks for weed smell:
10. Talk to your landlord
If you rent, make sure that you and the neighbor smoking weed are clear on the rules and policies of the building.The landlord is responsible for sorting out the problem if your neighbor continually violates the rules.
How to get rid of weed smell from previous owners
If youโve recently moved into your new home and thereโs a definite whiff of weed smell, follow these tips:
1. Clean the whole place from top to bottom
You need to go deep and give your home a thorough cleaning. If youโre forgetful, why not print out this handy checklist?
โ Wash walls, ceilings and hard surfaces โ simply use a mild soap or another appropriate cleaning product and rinse well. Also, be sure to scrub inside cabinets, drawers and closets.
โ Steam-clean your upholstery โ you can purchase special shampoos that actively remove odors rather than just masking them.
โ Wash the curtains โ donโt forget about blinds as well. Using an all-purpose cleaner, you can soak these in a bathtub. After scrubbing, hang to dry.
โ Clean the carpets โsmoke particles can get embedded in carpets, so itโs essential to clean them to remove the smell.For a deep clean, itโs worth getting them professionally cleaned.
โ Wash the windowsโ hot sunshine can warm windows covered in smoke and then spread the smell throughout your home.
2. Use natural deodorizers
As we already talked about, some great natural deodorizers can remove smoke smells. White vinegar and activated charcoal, in particular, are highly effective. You could pour some into a bowl (or bowls) and leave overnight to absorb the smell.
Tip
You can also sprinkle baking soda on carpets and upholstery. Let it sit for a few hours, and then vacuum it up.
3. Repaint your walls
If you can still detect weed smells after deep cleaning, you may need to repaint the walls.
Tip
Be sure to go for a high-quality paint that has a primer, however, as this will help lock in lingering odors.
Just like tobacco, the smell of weed can easily travel through to your home if your neighbor smokes, especially if they do so inside their apartment. And as marijuana has such a pungent odor, it can be even more noticeable than cigarette or cigar smoke.
This is because the particles within smoke are airborne and incredibly small, meaning that they can get through surfaces such as plaster. That said, itโs more likely that smoke particles will stick to the walls rather than travel through them.
However, you might be experiencing weed odors because the smoke might be getting into your home via small cracks, tiny holes or pores in the shared walls. Another alternative is that weed smoke and its associated smells are coming through the electrical outlets, windows and doors.
The intensity of the smell depends on various factors, such as how much your neighbor smokes, the thickness of the walls and your building or unitโs ventilation quality.
Final thoughts
Whether itโs creeping into your apartment from next-door neighbors or still lingering from previous owners, removing weed smoke odor from your home can be tricky. Yet you can do many things to make your apartment smell fresh again.
Ventilation is crucial, but you can also try using some natural odor-absorbers like white vinegar and charcoal. An air purifier with HEPA and activated carbon filters can also mitigate strong odors.
And donโt forget that simply having a friendly chat with a neighbor who smokes weed may just do the trick.
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.

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 weโve got enough cylindrical air purifiers at home.
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 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.
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
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.
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.
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 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:
Unplug the unit
Remove the front panel by pulling it (it’s magnetized, so you don’t need to unclip anything)
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)
Attach the pre-filter to the new filter and insert it the same way you removed it.
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 feetโroughly 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 weโve 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.
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.
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.
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.
If youโve researched air purifiers, youโre likely to have come across the brand Levoit. Since 2017, this company has been producing innovative air purifiers at price points that suit every consumer.
One of the latest innovations from Levoit comes in the form of their โSโ (aka smart) range. Levoit realizes that modern household devices are frequently becoming more reliant on app-based controls; I mean, who wants to get up to adjust settings these days?
Therefore Levoit has developed, what they call, the VeSync app that allows you to monitor and control your air purifier from anywhere in the world with a WiFi connection. Available on both Apple and Android devices, you can:
Set timers
Create schedules
Adjust modes and fan speeds
Monitor your current air quality
Receive important notifications about your device
Tip
Also if you have more than one Levoit S device in your home, you can control each one through the same app.
Both the units weโre pitting against each other have this capability and many other similarities, but when it comes down to it, which air purifier do you want to spend your hard-earned dollars on?
We will evaluate each unit in sections to show you the similarities and differences between the Core 300S and the Core 200S, choosing a winner for each category. Then weโll put it all under consideration and choose an overall winner.
TL;DR Which unit wins overall?
โIt’s more powerful and a little bigger, but the Levoit Core 300S is the perfect ratio of power to cost. In comparison, the 200S will cost the same long term but will always be struggling unless you use it in a tiny room.โ

When you put the specifications of these two units side-by-side (which we haveโฆscroll down), the data from both Levoit and our performance tests show us that the 300S wins hands down.
Even though these two are similar in size, the 300S boasts a CADR (Clean Air Delivery Rate) of 141 CFM (Cubic Feet per Minute), while the 200S hangs behind with 118 CFM.

The design
Regarding the design aesthetics, I have chosen the Core 200S as our winner. This was a close call as they both look so similar, but I think the 200S looks slightly more modern and ergonomic.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
When you compare them to designs from Blueair or Coway, Levoitโs Core range isnโt the best-looking air purifiers out there, but theyโre also not the worst. These air purifiers look incredibly similar, with the 300S having a band around its middle and a fraction bigger, but thatโs about it.
I chose the 200S as a winner merely because it looks a little sleeker than the 300S.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
A great design point that both air purifiers possess is that theyโre so easy to move between rooms. The 200S, weighing 6.6 lbs, and the slightly larger 300S, weighing 5.95 lbs, easily fit underneath your arm when transferring them to a different space.
As you can see, the differences are few and far between. Apart from the slight size difference, the recessed top grill and the gray band around the middle of the unit, you couldnโt tell them apart.
The control panel
The winner is the Core 300S. Both control panels have different pros, but the 300S has a color-coded air quality monitor ring and an LED display to show how long your timer is set for.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
First, let’s look at the 300S. The design and layout are similar to the Core 300, with a few subtle differences. The 300S comes with the addition of AirSight Plusโข technology that monitors the air quality in your room in real-time. The information is then displayed on the control panel as a color-coded light ring.
The 300S also has an auto mode controlled by the information from the air quality sensor.
When in auto mode, the 300S will change its fan speed in accordance with the PM2.5 in the air. A low PM2.5 (good air quality) will set the fan to its lowest speed, and a high PM2.5 (bad air quality) will increase the unit’s fan speed.
Along with auto mode, the 300S also features four fan speeds, including sleep mode, display lock, display light control and a timer that can be set to any countdown from 1-12 hours and uses its LED screen to display.
The 200S also comes with sleep mode, display lock, display light control and a timer, but can only be set to 2, 4 or 8-hour countdown. Unfortunately, the 200S doesnโt include Levoitโs AirSight Plusโข technology, which, in turn, means there is no auto mode, and you canโt monitor the air quality in your home.
The controls on the 200S also has a filter indicator light that illuminates when the filters are ready to be replaced and a button that turns its night light on and off, which doesnโt appear on the 300S.
Air filtration technology
When it comes to filtration technology, the Levoit Core 300S wins in our view due as you can customize the filter to your needs with four different replacements to choose from.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
Levoitโs โoriginalโ filter thatโs included with your 300S has three stages made up of a pre-filter (to capture larger particles like dust), a main particle filter and a layer of activated carbon filter for odors and gases.
You can replace the original filter with three other types of filters. If you have pets, the Pet Allergy Filter is engineered to tackle removing pet odors and alleviating allergies. If you live in an area with high levels of smoke, fog and VOCs, go for the Toxin Absorber. For ultimate protection, thereโs the four-stage Smoke Remover Filter that includes Custom High-Efficiency Activated Carbon.
With the 200S, there is only one filter option available, but that doesnโt mean that itโs bad. Levoit includes a three-stage circular filter comprising a nylon pre-filter for larger particles, a main airborne particle filter and an activated carbon filter.
When you receive your new unit, along with all of the exterior packaging, remember to open up your air purifier before you turn it on. You will most likely find that the filter is also packaged in a plastic bag. If you donโt remove this bag before operating the unit, a. the filter wonโt work and b. It will probably start to smell like burning plastic.
Air cleaning performance
In our own performance tests, the Core 300S cleared our room of contaminants 16 minutes faster than the 200S, making it the winner for this section of the comparison spotlight.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
In order to assess air cleaning performance, we fill our 728 cubic feet test room with incense smoke and use our PurpleAir Zen laser particle counter to record how long it takes for the air purifier to bring PM1 pollution down to zero.
Even though many of the features of the 300S and the 200S are extremely similar, our performance tests showed a big difference in the effectiveness of their air-cleaning abilities.
When you look at the CADR of each unit, 300S = 141 CFM, 200S = 118 CFM, you know that there will always be a difference in performanceโฆand it shows.
The 300S outperformed the 200S hands down with a whopping 16 minutes difference in the time it took them to clear the pollutants from our room.
The 300S cleared our test room in 45 minutes
The 200S cleared our test room in 61 minutes
When you look at their performances side-by-side itโs easy to see how they compare to each other and similar air purifiers on the market.
Noise levels test
There can be no clear winner regarding noise levels, as both units emit the same amount of noiseโฆ this one is a draw.
A lot of brands like to label their air purifiers with buzz words like โWhisper quietโ and even Levoit class the 300S as โquiet as a gentle breeze,โ but no unit can be completely silent.
Air purifiers contain a fan and motor to run it that both make noise when theyโre active, so it becomes a matter of how big the fan and motor are, how hard theyโre working and how well made they are that dictate how loud or quiet an air purifier is.
On their quietest setting, the Levoit Core 200S reached 39.6 decibels, while the Levoit Core 300S was quieter at 38.9 decibels. And when running at its highest fan speed, the 200S reached 49.1 decibels against the 54.5 decibels we recorded when testing the 300S.
When you compare them to the noise levels of other air purifiers of the same size, you see that they are quieter than most.
Yearly running costs
The winner is the Core 200S due to its energy efficiency and lower cost filter replacements.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
1. Yearly electricity costs = $29.85 (200S) versus $22.92 (300S)
When you buy an air purifier, itโs not only the initial cost of the unit you need to consider. You need to think about how much it costs to run. Not all air purifiers are created the same, and the running costs will differ depending on which one you get.
Both these units are highly energy efficient, earning themselves certifications from the California Air Resources Board, Energy Star and the FCC. The Core 200S will cost you, on average, $29.85 a year if you run the unit for 24 hrs a day, 365 days a year. The Core 300S will cost you an average of $22.92 per year. This is due to its higher CADR, as the 300S is working harder than the 200S.
2. Yearly filter costs = $51.98 (200S) versus $59.98 (300S Original Filter)
Another running cost to be considered when choosing the right air purifier for your home is the cost of replacement filters. If you donโt replace them when prompted, your air purifier will become less and less effective.
With the 200S, there are only two filter options, an official Levoit replacement or an unofficial version. Weโve only tested out the official Levoit filters, so we canโt testament to the effectiveness of the unofficial version.
The official filters will set you back $25.99 each, and the unofficial filters are significantly cheaper at $23.39 for two.The filter in the 200S has to be replaced every 6-8 months:
With the 300S, four official filters are available and unofficial versions to match. This time, we only tested the official โOriginalโ filter, but weโre confident the other official filters will be highly efficient. Prices start at $29.99 up to $39.99 for the highest spec replacement. Levoit recommends you replace the filter in the 300S every 6-8 months:
Air purifier filters are the most efficient way of removing harmful contaminants from the air in your home. They work by trapping microscopic particles in a tightly woven maze of fibers, removing them from the air.
Bottom line: Should you get a Levoit Core 300S or a Core 200S?
Both of these units are high-performing air purifiers with smart features at a budget price.
โ If you want air quality updates, app control and a great CADR โ go for the 300S.

By introducing the Core 300S, Levoit have pretty much omitted the need for the 200S. Yes, itโs slightly smaller and doesnโt cost as much to run. Still, when it comes down to performance and efficiency, the 300S surpasses the 200Sโฆall for an extra $50.

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 โwater 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.
Iโm 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 didnโt 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.
How we test air purifiers
Read our full testing methodology.
We donโt 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
โThe first thing that made me wary of this device’s effectiveness was the lack of data about its cleaning power. The manufacturer doesnโt 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
If you donโt want to read my 2000-word review on this air purifier, then you can see my key points below:
What we really like
Itโs 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 doesnโt 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 shouldnโt be sold as an air purifier. This is a water-based fragrance diffuser.

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.
Itโs 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).
This simple control panel makes the Rainbow RainMate incredibly easy to use.
You just need to switch it on when itโs 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 ( = ).
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.
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?
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.
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.
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:
The cost to run a Rainbow RainMate: $11.35 per year
1. Electricity costs = $11.35 per year
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.
The Rainbow Rainmate pulled 10.7 watts without the lights running and 10.8 watts with the lights running.
Electricity consumption with light off
Electricity consumption with light on
10.7 watts
10.8 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, โIt 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.
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 โprizeโ 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 โFresh Air Machine.โ From reading many threads, itโs 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.
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 Energyโs 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.
Levoit and Blueair are heavyweight brands, producing air purifiers that are sold across the world.
Levoit has been making air purifiers for over ten years and has earned a reputation for releasing reliable and innovative products with a budget price tag. They have even developed their own signature technologies to use in their units like VortexAirโข, QuietKEAPโข and AIRSIGHTโข Plus.
With two decades of experience, Blueair is known for taking the style of air purifiers to new levels, even winning awards in design along the way. They donโt only concentrate on looks; Blueair strives to push filter technology across their air purifiers with HEPASilentโข Technology (electrostatic filtration with HEPA) exclusive to Blueair units.
These two units showcase each company at the top of their game with the Core 600S from Levoit and Blue Pure 211+ from Blueair, so we wanted to pit them against each other. But we didnโt want to go on power and cleaning ability alone; we know you (the consumer) have more needs and wants from an air purifier.
So read on, where we examine looks, controls, filters, electricity consumption, noise levels and air cleaning performance to see who will reign victorious in the battle of these two incredible air purifiers.
TL;DR: Which unit wins overall?
โWe always knew this would be a hard decision as these two units display amazing qualities. But ultimately I choose the Levoit Core 600S as our overall winner for its impressive air cleaning performance, added smart functions, low noise output and energy efficiency.โ

๐ Very simple to operate: you will do it all with just one button.
๐ It is super quiet considering its power.
๐ You can customize the design with a variety of pre-filter fabrics.
๐ Cleared our test room in 18 minutes.
๐ The mobile app is great and can connect to Alexa or Google Home.
๐ It offers a high CADR for a low price.
๐ It is easy to move around thanks to the handles at each side.
๐ Cleared our test room in 15 minutes.
What we think could be better
What we think could be better
๐ The HEPASilent technology in the Blue Pure 211+ uses a bipolar ionization process with the potential of generating small amounts of ozone, and this is a feature that cannot be disabled.
๐ After using the 211+ at home for a few years, the mechanism to open the top doesn’t hold as well so sometimes I accidentally open the device when trying to move it around.
๐ It’s too big and too heavy not to have a handle somewhere to make it easier to move around.
๐ The main filter in the 600S is not, in fact, a True HEPA filter as advertised initially by Levoit. This doesn’t affect its performance, but it’s something we need to mention here.
๐ It makes an annoying whirring sound at low fan speeds that might bother you if you’re sensitive to sound.
๐ The sensor needs to be vacuumed regularly to ensure accurate readings.
The specifications compared side-by-side
The Levoit Core 600S is the clear winner due to its higher CADR score, its fastest cleaning performance and the additional smart features.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
Both air purifiers retail at around $300, which is incredible value for money when it comes to performance. With a lack of extra features in the 211+, the 600S wins overall. It can also be used in larger rooms (up to 635 sq. ft. vs. 540 sq. ft.) and has a higher clean air delivery rate (CADR) of 410 CFM vs. 350 CFM (Cubic Feet per Minute) from the 211+.
The only other air purifier we have tested with similar performance is Smart Airโs Blast Mini, which is substantially bigger and retails at around $600.
When it comes to the design aesthetics, the winner is the Blueair Blue Pure 211+ due to its brightly colored, customizable pre-filter and cosmic-looking grill.
Donโt get me wrong, the 600S doesnโt look bad, but it just looks like a traditional air purifier. It has curved edges that are more aesthetic than a straight box shape and unobtrusive branding.
The problem is, thereโs not much else to comment on.
Design and look are subjective, and the 600S is great for those who donโt want their air purifier to be noticed, but with its lack of creative design, itโs a little too plain for my taste.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
Blueair, on the other hand, is a brand that uses design to set it apart from other brands producing โtraditionalโ looking air purifiers, making them extremely popular with consumers who want an air purifier to fit into their modern lifestyle.
A great feature Blueair offers is its customizable pre-filters. The 211+ uses an exterior fabric pre-filter that is not just easy to clean (helping extend the life of its HEPA filter) but also offers a chance to adopt different colors so that you can customize your air purifier to fit the aesthetics of your room. Choose from Crystal Pink, Buff Yellow, Dark Shadow, Lunar Rock or the classic Diva Blue.
When you stand them side-by-side, the differences are clear. Although theyโre both box-type units, the 211+ is more stylized with its fabric pre-filter and gloss top.
Ease of use and control panel compared
When it comes to the control panel, the winner has to be the Blueair Blue Pure 211+ with its one-button control, making it super easy to use.
The Blue Pure 211+ may not be able to connect to an app or have any smart functions like an auto mode or air quality monitor, but with its one-button design, the 211+ could be the easiest air purifier to operate on the market.
All you need to do is push the button once to turn it on, press it to scroll through the various fan speeds, then push it again to turn it off. You canโt get simpler.
The large button on the front also acts as a filter replacement indicator, so you know when itโs time to buy a new HEPASilentโข filter. It will automatically glow yellow after five months of operation, giving you time to buy a replacement; when the filter is full, it will glow red to indicate that you need to install the new filter.
That said, the control panel in the Levoit Core 600S is also pretty good, if a little more complex:
Levoit has packed the 600S with additional features like an auto mode, sleep mode, timer, numerical & color-coded air quality monitor and the ability to turn off the display lights. But all of these functions need a button to operate them.
Yes, itโs intuitive and each button is spread out in a circle; nevertheless, the buttons are touch-sensitive and sometimes donโt activate on the first press, which can be frustrating.
The best control function Levoit has for its S range is the ability to control your air purifier using the VeSync app on your smartphone. Itโs easy to set up and once your device is connected, you can control the settings and fan speed, turn it on/off and monitor the air quality in your homeโฆfrom anywhere in the world with an internet connection.
Air filtration technology compared
The Levoit Core 600S wins in our view due to its HEPASmartโข technology + concentration of activated carbon. Plus, we donโt like the fact that the ionizer in the 211+ cannot be turned off.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
Levoit provides us with a three-stage circular filter inside the Core 600S that will remove harmful airborne contaminants (dust, bacteria & viruses, smoke, mold and allergens) by trapping them in its tightly woven maze of fibers.
In addition to this, the filter in the Core 600S contains loose-fill pellets of activated carbon over a bonded sheet. Weโve found that loose-fill carbon is a hell of a lot more effective at removing odors and VOCs (Volatile Organic Compounds) and have a longer lifespan over bonded carbon sheet filters like the one you will find inside the Blue Pure 211+.
The 211+ comes with, what Blueair calls, a HEPASilentโข filter. According to Blueair, โdual filtration delivers up to 45% more clean air faster, using up to 67% less noise and energy than HEPA filtration alone.โ It gives particles an electrostatic charge to cling to the filter more effectively. According to Smart Air, the technology is the same as the one used in ionizers โ itโs unfortunate that the user canโt deactivate this function, considering they can produce ozone.
Unlike the 600S, you can remove the pre-filter from the 211+ and wash it, prolonging the life of the HEPA filter as it removes larger particles from the air leaving the HEPA to deal with the smaller ones.
Tip
HEPA filters work by trapping contaminants when they become full of particles; they need replacing periodically with new ones to keep them effective.
When it comes to replacing the filters, both Blueair and Levoit keep it simple:
Always remember that when you get your new air purifier, the filter is usually inside the unit wrapped in a protective plastic bag. If you donโt remove this packaging before switching your air purifier on, it wonโt work properly, and youโll probably start to notice the smell of burning plastic.
Air cleaning test results compared
The Core 600S wowed us when we put it through our performance tests. It cleared the simulated contaminants from our testing room in just 15 minutes! Making it one of the fastest-performing air purifiers we have tested.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
If youโve read any of our product reviews before, youโll know that we donโt take manufacturers’ specifications as gospel. We conduct our own performance tests in a real-world environment to compare different air purifiers under the same conditions.
To see how efficient each unit is at removing pollutants from the air, we fill our 705 cubic ft office full of simulated contaminants (smoke from incense sticks). We then introduce an air purifier, crank it up to its highest fan speed, and measure how long it takes the unit to clear the room of smoke pollution with the help of our indoor sensor from Purpleair.
As with the other categories, the fight for the best-performing unit was another close call. Both the Core 600S and the Blue Pure 211+ performed amazingly in our home tests with only three minutes between them.
The data from our indoor sensor only shows us minute differences between each of these air purifiers. As you can see from the sharp decline in the results charts below, both the 600S and the 211+ spring into action, clearing even the smallest pollutants from our room at speed.
The Levoit Core 600S cleared our test room in 15 minutes
The Blueair Blue Pure 211+ cleared our test room in 18 minutes
As we test all of the air purifiers we review, we can compare them with other units to see how well they perform against each other.
The chart below shows the performance of our two competitors matched against some of the other high-performing units weโve reviewed.
Even though the 600S and 211+ are considered low-budget air purifiers (costing around $300 each), they out-performed units with much higher price tags.
For example, the Blast Mini from Smart Air is double the price and more than double the size of the 600S and the Alen BreatheSmart 75i can set you back around $750 and isnโt nearly as stylish as the 211+.
Noise levels test results compared
The Core 600S is five decibels quieter than the Blue Pure 211+ when running at its lowest fan speed level.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
All air purifiers make noise unless they are turned off. Inside the unit are a fan and a motor that will make a whirring sound that escalates as the fan speed increases. Brands often use words like โsilentโ or โwhisper quiet,โ but this doesnโt mean they are mute.
The Core 600S emits 26 dB (equivalent to a whisper from five feet away) at its lowest fan speed and 55 dB (equivalent to a refrigerator) at its highest, while the Blue Pure 211+ produces 31 dB (equivalent to a whisper nearby) at its lowest fan speed and 56 dB (equivalent to an electric toothbrush) at its highest. So, not a whole lot of difference there.
Comparing these two air purifiers with other units we have tested, you can see from our noise comparison chart that theyโre both pretty average regarding the sound they produce.
Tip
The perception of what is noisy and what is not can be quite subjective. That is why, we always shoot a video so you can get an idea of how it sounds at each one of its fan speeds:
Regarding expenses you can expect to pay in the long run, the winner is the Levoit Core 600S again due to its energy efficiency and lower filter replacement costs.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
1. Yearly electricity costs = $51.51 (600S) versus $64.12 (211+)
When buying a new air purifier and the initial cost of the unit, you need to keep in mind its running costs. After all, you donโt want a shock when your energy bill comes in.
Different air purifiers have different-sized motors, that take different amounts of electricity to run. With the rising energy costs globally, itโs best to know how much it will cost to run a unit before you buy it.
For the size and cleaning power of these two air purifiers, they are both very energy efficient. Our performance tests revealed that the 600S pulled 49 watts at full fan speed and low 6.2 watts at its slowest. On the other hand, the 211+ pulled 55.5 watts on high and 16.7 watts on low.
2. Yearly filter costs = $100 (600S) versus $139.98 (211+)
Another high running cost to factor into your purchase is replacing your air purifiers’ filters. Brands offer different filter lifespans and charge different prices for replacement filters, usually dependent on size and strength. The good news is that in most cases, you will be able to purchase generic filter replacements at a cheaper cost.
The average lifespan of a HEPA filter in an air purifier is around 6 months, but these guidelines depend on the specific air purifier, how often you use it and how much pollution the filters remove.
The filter in the Levoit Core 600S has to be replaced every 6 months:
HEPA filters effectively remove airborne contaminants from rooms as they trap and keep those microscopic particles in their tightly woven maze of fibers. As they capture more and more particles, the filter starts to become full and, in turn, less effective. Thatโs why you need to replace them periodically.
Bottom line: Should you get a Levoit Core 600S or a Blueair Blue Pure 211+ ?
Both the Levoit Core 600S and Blueair Blue Pure 211+ are high-performing, powerful air purifiers. So, which one is best for you?
โ If you want smart functions, a mobile app and worry about ozone โ go for the Core 600S.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
โ If you want a customizable design and value simplicity in the control panel โ then the Blue Pure 211+ is the unit for you.
While the 600S has added functions and higher cleaning power, the 211+ has the looks and is easier to operate. But both are fantastic value for money regarding the unit’s initial price and running costs.
HouseFresh strives to give you open, honest, accurate and unbiased reviews. We donโt just research the products we review; we buy them with our money. This allows us the freedom to give you our real opinions, whether they be good or bad. Having the products in our hands allows us to put each air purifier through its paces to see how it operates in a real-world scenario.

Smart Air isnโt 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 Airโs 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.
Hereโs how we tested the Smart Air QT3:
In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
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.
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.
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.
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.
We track sound levels emitted by the air purifier at different fan speeds with the help of a commercial sound meter.
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
โThe 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

The QT3 looks great
This portable air purifier features a super-sleek design, as expected from a company like Smart Air.
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 weโve tested, the QT3 has a plastic handle that makes it easier to carry around.
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 weโve tested. In comparison, itโs 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.
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.
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
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.
The QT3 purifier contains no ionizers and doesnโt 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.
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.
The other portable unit we like is the Pure Enrichment PureZone Mini. The PureZone Mini has activated charcoal, but itโs so tiny that we didnโt 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
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 weโve 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 isnโt a cleaner that will cost a lot in bills as itโs 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.
BREATHE CLEAN AIR: Take a breath of fresh air! Our HEPA filters 0.3-micron as well as 0.07-micron airborne particles
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 itโs one of the top portable air purifiers on the market.
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.
SOURCES
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.
If you don’t have time to read this full article, here’s a summary of what we will cover:
Ionizers can slightly improve the efficiency of mechanical air filtration of HEPA and activated carbon filters, boosting the ability of the unit to remove particulate matter and odors from your environment.
Unfortunately, they do this by generating and releasing negative ions into the air, which can produce a harmful gas called ozone and also increase small particulate matter (PM2.5) levels along the way.
In this article, weโll dig deeper into what an air ionizer is, its potential harm and its limitations.
Ready to learn more? Letโs get to it!
What does an air ionizer do?
For this one, youโll have to think back to your high school chemistry lessons.
Ions are so minuscule that theyโre invisible to the human eye. Nevertheless, theyโre all around us, floating in the air.
Remember particles and molecules? Theyโre all made up of ions, which can have either positive (cation) or negative (anion) charges. Negative ions (anions) become negative when they gain an electron, whereas positive ions (cations) become positive when they lose an electron.
Unlike an air purifier, which works by filtering through a series of finer and finer filters, an air ionizer generates negative ions, which are then released into the surrounding air.
These are then attracted to positive particles in your atmosphere, such as cigarette smoke. This creates an electric charge, which causes the particles to stick together.
Once stuck together, they land on surfaces around you. This can include your ceiling and walls, floors and tabletops and furnishings, such as curtains, rugs and carpets.
These clumped-together particles can then be removed and cleaned away. Sometimes, the ionizer will have metal plates built-in, which collect the particles for you. You will, however, need to wipe these down from time to time.
Are you still with me?
Now that you understand how ionizers work, let’s go over some research about their air cleaning efficiency and the effects they can have on our health.
The pros and cons of air ionizers
While ionizers can be beneficial, they canโt completely clean up your environment.
Letโs get into the pros and cons:
Air ionizer pros
Ionizers can remove certain-sized particles from your environment. The result is that odors may be removed, which can help make your air feel fresh.
A 2018 study found that negative ions could efficiently remove particulate matter, even including ultrafine particulate matter. They were also able to kill mold and fungi.
A 2013 study also found that exposure to negative ions in high-density could contribute to a lower depression score, decrease stress and positively affect sleep and comfort levels.
Another study conducted in 2021 also found that positive and negative ions could significantly create an antibacterial atmosphere against bacteria. The study concluded that air ionizers would be handy for tackling airborne bacteria and infections.
Air ionizer cons
The EPA notes that ionizers are ineffective at removing gasses (such as VOCs), odors, pollen and house dust from your environment. They can even create VOCs as a by-product.
Ozone is also generated as a by-product of ionizers, a known lung irritant harmful to your health. There can be all sorts of harmful side effects from inhaling ozone, which in the short term can include:
– Irritation of the throat – Chest pains – Coughing and shortness of breath – Breathing difficulties
In the long term, you could also be looking at more serious lung conditions. A 2008 study found that ionizers were generally not strong enough to affect particulate levels unless they were particularly strong.
Another 2008 study also found that in addition to ozone, formaldehyde and ultrafine particulate matter were released into the atmosphere by ionizers.
HouseFresh doesnโt recommend air ionizers
โResearch shows that negative ions could enhance the ability of an air purifier to remove particulate matter and odors, including mold, fungi and even bacteria.
However, ionizers can generate ozone, VOCs and nitric oxide, leading to many health problems. That is why we do not recommend air purifiers that use this technology to anybody with respiratory issues or serious illness.
In our opinion, ionizers are not worth any risk when HEPA and activated charcoal don’t create chemical byproducts and work exceptionally well at removing harmful particles and gases from the air.
That being said, there are many good air purifiers on the market with ionization technology that can be turned on and off (such as the Winix 5500-2) for those who want to supercharge the air-cleaning performance of their units in specific situations but who prefer not to have an ionizer running in the background all the time.โ
โ Danny Ashton, HouseFresh Founder & Senior Writer
Still, even wildfires that donโt directly threaten your home can be dangerous because of their main byproduct: Smoke.
All homes โbreathe,โ and smoke can get in via joints, cracks and tiny gaps via a process known as infiltration. Wildfire smoke contains tiny, invisible particles and other contaminants that can cause many potentially dangerous health problems, including:
โ Bronchitis
โ Asthma attacks
โ Heart attack
โ Stroke
โ Lung cancer
โ Decline in cognitive function
The best defense is a good offense: Learn how to smoke-proof your home.
The three-step strategy to smoke-proof your home
If you have wildfires, check the AirNow website to anticipate air quality dangers.
Then follow our three-part strategy to smoke-proof your home โ Seal, Circulate, Clean:
Seal. Shut windows and doors, and inspect and repair caulking and weather stripping to eliminate gaps. Close outdoor intake dampers or vents on your central air conditioning systems as well as any window-mounted ACs. If you have portable ACs installed, check the seal around the exhaust mounts in the windowsโor remove them altogether and close the window.
If there are gaps under doors or anywhere else in the houseโplaces where you can feel a draft on windy daysโfill them in as best you can. Expanding foam, window and door caulk, or even old rags or leftover insulation can be used as short-term solutions to stop smoke from entering the home.
Circulate. Itโs best to keep air moving inside the house to keep it fresh and to maintain climate controlโif wildfires are nearby, staying cool inside the house is essential for your health and safety. If you canโt cool down the house, itโs best to evacuate if you possibly can because heat is a serious threat during a wildfire.
A key caveat here is to make sure your air conditioning systems are set to โrecirculate modeโ so they only cycle the air inside the house. If your system doesnโt have this setting, or if there is an outdoor damper or vent that you canโt close (or if itโs a single-hose portable air conditioner, which can pull air (and thus, smoke) into the room from the outside), donโt use your AC.
Clean. No matter how well you insulate and prepare your home for wildfires, thereโs a chance some smoke will get inside. The EPA recommends creating a โclean roomโ thatโs free from all air contaminants, including cooking or smoking, that can be used to reduce your exposure to wildfire smoke. Using an air purifier or air cleaner to keep the air inside a clean room or elsewhere in your home free from the fine particles that travel in wildfire smoke is a very good idea. Make sure your air cleaner has a high-efficiency filter, and run it at the highest setting as much as you canโremember, you may not be aware of particles in the air because they are so small.
Additionally, having some N95 respirator masks on hand is also an excellent idea if youโre going to ride out a wildfire in your home. This way if your efforts to keep the indoor air clean and circulating arenโt sufficient, or if you need to go outside for any reason, you will be protected from smoke and particles in the air.
Protecting your home during a wildfire
Wildfires move very fast and your home represents a rich fuel source. Most houses that burn down during wildfires ignite due to embers and burning debris carried by the wind, which means you can take steps to help protect your home.
This starts with understanding what the National Fire Protection Association (NFPA) calls the Home Ignition Zone, which is divided into three main categories:
Immediate Zone: 0-5 feet (this includes the home itself)
Intermediate Zone: 5-30 feet
Extended Zone: 30-100 feet
The Immediate Zone is crucial because embers can land on your home and start a fire. If wildfires are approaching your property, itโs best to start with the structure of your home itself and then work outwards from there to reduce flammable materials.
– Trim tree branches that overhang the home and trim branches within six feet of the ground.
– Inspect roof shingles and replace them as needed; embers penetrating the roof are common causes of home fires during wildfires.
– Inspect attics for openings allowing embers to enter the home and add 1/8th-inch metal screens to all vents. Adding wire mesh to screened-in areas like porches to resist embers is also a good idea.
– Remove all plants from the Immediate Zone, including landscaping. If thereโs a lawn, make sure it is hydrated. If itโs dry and brown, cut it as low to the ground as possible.
– Clear dead leaves and other debris from under decks and porches and between boards.Remove any materials that could ignite from floating embers.
– Instead of mulch, use crushed stone or gravel in your landscaping.
– Replace your roof with fire-rated products such as composite, clay, concrete shingles, or metal.- Replace siding and exteriors with fire-resistant materials like concrete siding, brick, plaster, or stucco.
– Replace your windows with dual-pane windows utilizing tempered glass in at least one pane.
– Single-pane windows can crack and shatter in extreme heat, allowing ember and smoke penetration.
The Intermediate Zone is where you can slow down a wildfireโs advance. While the immediate zone is about eliminating combustible materials, this area is more about spacing and maintenance.
– Replace soft landscaping with hardscaping where possible to reduce potential fuel sources.
– Ensure any structures are built using fire-resistant materials.
– Create fire โbreaksโ with non-flammable materials, e.g., pavement, pavers, or gravel at regular intervals.
– Clear vegetation under trees to prevent the spread of flames to branches and canopies.- If possible, maintain a minimum space between trees of 18 feet.
The Extended Zone will be your first opportunity to minimize a wildfireโs impact on your property. The goal here isn’t to eliminate a fire but to interrupt the fire’s path and keep flames to a minimum.
– Regularly clear ground of flammable materials, including dead vegetation, to reduce fuel.
– Keep any buildings or structures clear of ground plants or climbing plants.
– Ensure any structures in the Extended Zone are built using fire-resistant materials.
– If possible, maintain a minimum space between trees of 12 feet (within 30-60 feet from home) or 6 feet (within 60-100 feet from the home).
The best air purifiers for wildfire smoke
No matter how well you seal your home, smoke and dangerous particles can enter. A high-quality air purifier is vital to protecting your home and your family from the dangers of wildfire smoke.
HouseFresh performs exhaustive in-house performance testing on different air purifier models, collecting a wide range of data.
Using the data from these hands-on tests, weโve compiled our top three recommendations (including a Best Overall selection) for air purifiers that are most effective at removing wildfire smoke from your homeโs air depending on the size of the room being serviced, your budget, filter life and overall performance.

Final thoughts
Wildfires are frightening and destructive, burning anything in their path indiscriminately. If your home could be in the path of wildfires, you can take steps now to reduce the fire risk from floating embers by using suitable fire-resistant materials.
Remember you can protect your family by devising an evacuation plan that can be implemented without delays. But smoke is just as dangerous as the flames, so you also need a plan to keep the air inside your home safe and breathable.
Make your house as smoke-proof as possible by sealing gaps and ensuring the interior air is circulated and cleaned aggressively.
Sadly, most โbest air purifierโ lists you will find ranking on Google or YouTube are nothing more than the latest list of the best-selling devices, regardless of whether they will be suitable for large spaces.
In fact, most air purifiers are designed for small spaces (up to 300 sq. ft.), so the units recommended by big media publishers generally don’t pack the power needed to clean very large rooms. That can lead you to buy an underpowered air purifier that won’t be effective at keeping the air clear of pollutants because it just can’t clean the air fast enough.
For large rooms, you need an air purifier with a high clean air delivery rate (or CADR) to provide the recommended 4.8 air changes per hour needed to help reduce the level of particulate matter in the air. That is why all our picks for large spaces have a high CADR.
Of course, we didn’t stop there.
Before we put together the list you’re about to read, we tested the air cleaning performance of every air purifier by burning an incense stick in our test room and using two PurpleAir laser particle sensors to track how long each unit needed to remove the smallest particles (PM1) from the air. And that was just the first of many tests…
How we test air purifiers
Read our full testing methodology.
But we donโt just test our devices; we live with them. Our home is full of air purifiers, so we can uncover things that testing in isolation wonโt reveal โ from how easy it is to clean the pre-filter to how reliable the auto-mode or the app is.
Based on our first-hand data and experience living with these devices, these are the best large-room air purifiers available to buy right now.

Now, if video is your thing, you might prefer to watch the video version of this article:
Iโve chosen air purifiers with individual strengths because we all have different needs. Whether it be performance, sound, size or budget, this guide has something for everyone.
1. The best overall: Smart Air Blast Mini
A BIG air purifier with a huge fan and filter that still manages to clean the air quietlyโthe best-performing air purifier for rooms up to 703 sq. ft.
The CADR for this air purifier is 435 CFM (740 m3/h). Smart Air recommends it for spaces of 915 sq. ft. (85 m2), but based on our calculations, you will get 4.8 air changes in rooms up to 703 sq. ft. When we tested it running at top speed, it cleaned our test room in 12 minutes, which was quicker than any other device we had tested:
What is even more impressive is that the Blast Mini still managed to clean our test room in 16 minutes when running at its lowest fan speed which produced less than 45 dB of sound. This air purifier truly blew my mind.
Sure, the PC fan DIY kit air purifiers still provide quieter operation, but for pure air cleaning power at sub-45 dB, the Smart Blast Mini MKII is the device to beat:

What we really like
It is made out of metal, and while itโs heavy, it comes on wheels. Compared to most other air purifiers, this device can take a lot of knocksโperfect for a location like a school.
The lack of smart features. You donโt need to worry about app connectivity or WiFi connection. If there is a power cut, this device will come back on automatically when the power is restored.
The pre-filter is easy to remove for regular cleaning. It is better to have a removable pre-filter like the one that comes with the Blast Mini compared to cylindrical air purifier designs, where you need to remove the entire filter just to clean the pre-filter.
What we think could be better
It is not cheap. This air purifier will set you back around $599 if you’re buying from the U.S. or ยฃ450 if you’re in the UK.
It is far from ‘mini’. This is a heavy air purifier (59 lbs or 26.8 kg), and you canโt hide it away. It is called Mini because it is the small version of Smart Airโs Blast air purifier, which is basically a wall on wheels.
It gets noisy at top speed(56.3 dB). That said, you can run the Blast Mini at its lowest fan speed and it will still provide you with clean air faster than the majority of air purifiers on the market todayโand it is good to have that extra power there in case you need it!
Behind the stylish front cover of the Blast Mini, you will find an incredibly powerful fan and a huge, long-life H13 HEPA filter. It is worth mentioning that the Blast Mini doesnโt have an activated carbon filter as standard, so if you are looking for an air purifier to help tackle unwanted smells or VOCs in a large room, I highly recommend you spend a little extra to add a carbon filter.
There are no special bells and whistles on the Blast Mini like auto mode, air quality monitor or touch-screen control. Founded by people who werenโt happy with the cost of air purifiers, Smart Air set out to produce high-performing, low-cost, no-thrills units that do their job really well. That is why their devices donโt have sensors or any smart features, so I use my Blast Mini connected to our Philips Hue system to run it on a schedule that works for our home.
At $149.99, the AirFanta 3Pro is the most affordable high CADR air purifier on the market today for spaces up to 671 sq. ft.
Use the discount code HOUSEFRESH for 5% off when buying directly from AirFanta.
The design of the AirFanta 3Pro is inspired by the Corsi-Rosenthal box: a base at the bottom, a custom-made HEPA H11 filter on each side and an array of powerful PC fans on top. At its highest fan speed, it has a CADR of 436 CFM, so it can provide 4.8 air changes per hour in rooms up to 681 sq. ft.
Looking at those figures, you can probably understand why the 3Pro earned a spot on this list. Try finding a traditional HEPA device with a CADR north of 400 cfm for less than 150 bucks!
When running at its top speed, the 3Pro cleaned our 728 cubic ft. test room of all traces of PM1 particles in just 14 minutes with HEPA filters only and 18 minutes with HEPA + carbon filters.
When calculating the total running costs associated with running an AirFanta 3Pro at full speed every day, you can expect to spend $125.23 per yearโthis aligns with the running costs you will see with other popular air purifiers:

What we really like
The AirFanta 3Pro was designed to be portable. It can be disassembled and reassembled in just a few minutes, and it fits inside a carry-on luggage or even a medium-sized backpack.
It is small but incredibly powerful. It took just 14 minutes to clean our test room, which is just two minutes slower than the much larger Smart Air Blast Mini.
It comes with a power adapter to control the speed of the fans and the noise output. I tested it at lower voltages and still achieved solid air cleaning performanceโwhen running at 8V, it generated 47.2 dBA of noise and cleaned our test room in 17 minutes!
It is the cheapest PC fan-powered air purifier you can buy today. It is not only cheaper but also A LOT easier to put together than a standard DIY PC fan air purifier kit.
What we think could be better
It is the noisiest PC fan air purifier we tested. When running at top speed, we measured 56.3 dB, which is as loud as standard shop-bought HEPA devices.
It is the most electricity-hungry PC fan air purifier we tested. Energy costs are similar to standard retail HEPA devices when running at full speed.
You will not find any other air purifier with a CADR above 400 that you can bring along with you wherever you go. This makes the AirFanta an excellent choice for events and shows.
Like the Smart Air device, it doesnโt have any smart features, but the power control allows you to find a sound level you’re happy with. For those wanting to clean a large room for the best bang for the buck, the AirFanta 3Pro is our top choice.

The Luggable XL is another air purifier powered by PC fans that was also inspired by the Corsi-Rosenthal Box. While traditional CR boxes use box fans and work well, they also take up a lot of floor space and run loud. CleanAirKits improved on that design by bringing together a combination of powerful PC fans with HVAC filters, allowing the Luggable XL to clean the air effectively without excessive noise or energy usage.
We went with the 7 Sickleflow versions of the Luggable XL, which costs $227 as a kit without filters and $299 fully assembled. This version has an estimated CADR for dust of 323 CFM and in our testing, it cleared all PM1 pollutants inside our 728 cubic ft. test room in 20 minutes:
20 minutes is very good performance, matching what we saw with popular retail units like the Winix 5500-2 (20 minutes), the Levoit Vital 200S (18 minutes) and Philips 3000i Series (18 minutes). However, the thing that impressed me the most was the level of sound we recorded with our sound level monitor:

What we really like
It is the best performing quiet air purifier we have tested. As you can see in the table above, most HEPA retail devices running at their top speed are much louder than the 38.8 dB we recorded for the CleanAirKits Luggable XL-7.
The fans are standard PC fans and can be swapped out easily. I opted to go with the Cooler Master SickleFlow 120 fans offered by CleanAirKits on their website, but I could easily replace these if anything were to happen with the Cooler Master fans.
You can use any 25x20x1 HVAC filters. Although I do recommend choosing the 3M Filtrete 1900 MERV13 as they are some of the best we have come across.
It is incredibly energy-efficient, even with seven PC fans. In our tests, our Luggable XL-7 pulled just 10.55 watts! If you had to leave this device running 24/7, it would only add $11.09 to your yearly energy bill.
What we think could be better
It is not cheap considering you need to build it yourself. If you donโt need a super quiet air purifier, then you can get similar air cleaning performance for less than $150 with devices such as the AirFanta 3Pro. That said, there are many variations of the Luggable that could mean you get yours pre-assembled or even with less fans, which could help reduce the price.
It could be less durable than standard shop-bought HEPA devices or something like the Nukit Tempest. The design of the Luggable XL means that the filters are exposed, so they could be easily damaged if you are not careful.
Even though upfront costs can get a bit high depending on what options you go with, the CleanAirKits Luggable XL will be much cheaper in the long term thanks to the use of HVAC filters and the lower energy usage from the PC fans.
So, for those who want a super quiet air purifier for a large room, then look no further than the Luggable XL as it can provide five air changes per hour in rooms up to 485 sq. ft. while generating 38.8 decibels of noise.
If you want a device that can handle dust from large construction areas or gases inside big workshops, then consider this beast. The CleanShield HEPA 550 is suitable for 800 sq. ft. and has a reported CADR of 550 CFM. You can even daisy chain three of these devices together for a total combined airflow of 1650 CFM.
The AlorAir CleanShield HEPA 550 can quickly remove particles and gases in large spaces thanks to its combination of filters: You get one layer of HEPA + activated carbon, and then another layer with a MERV 10 filter for larger particles.
When we tested it in our test room, all PM1 particles were reduced to zero in a speedy 16 minutes. This landed the Alorair Air Scrubber 550 at the top of our leaderboard for air cleaning performance – but it doesnโt come cheap at $497 and it is super loud:

What we really like
The rotomolded polyethylene (LLDPE) chassis is super strong and durable. This is the perfect choice for those looking for something less delicate than the usual shop-bought HEPA devices to be used in a construction zone or a large workshop.
Its stackable and can be daisy-chained. You can connect multiple units together to achieve even greater air cleaning capability. However, Alorair recommends not stacking more than two units on top of each other.
It comes with a 10-year warranty. This is something we only see with long-standing manufacturers like IQAir or Alen, which makes their units more of an investment.
What we think could be better
The Alorair Air Scrubber 550 is the loudest air purifier we have ever tested. When we recorded noise levels generated with a sound meter from 3 ft. away, we measured 74.5 dBA at its top speed.
This device uses A LOT of energy, pulling 224 watts at its highest fan speed. This makes the Alorair 550 a very expensive option in the long run: assuming 24/7 operation, it can add over $240 to your energy bill.
To be clear, I wouldnโt use this like a standard air purifier. But for those who want something durable for large spaces to deal with renovation pollution, construction dust or workshop fumes, the the AlorAir CleanShield HEPA 550 is one to consider.

5. The best DIY option: Corsi-Rosenthal Box
A DIY air purifier for those who donโt want to buy another device for their homes that will be effective in rooms up to 680 sq. ft.
If you already have a box fan somewhere at home, you might be able to build an air purifier powerful enough for spaces as large as 680 sq. ft. Iโm talking about a device that went mainstream during the first wave of the COVID-19 pandemic: the Corsi-Rosenthal box.
The brainchild of Dr. Richard Corsi and Jim Rosenthal, this do-it-yourself unit uses the basic principle of what an air purifier is: a fan and a filter. The CR box consists of four (or five) HVAC filters attached to a box fan using tape. There are no fancy functions or features, auto mode or air quality sensors, which can be a con or a pro, depending on your opinion.
This is a great option if you need an air purifier right nowโeven the EPA has produced a study on DIY filters and found the Corsi-Rosenthal box to have the highest level of cleaning power for dealing with wildfire smoke. The very best design uses five filters, a cardboard shroud and has legs. We haven’t tested this version yet but we did test two other configurations.
The CR box with four MERV 13 filters and no shroud cleaned our test room in 32 minutes:
And the CR box with four MERV 13 filters and a cardboard shroud cleared the air in 30 minutes, meaning that the shroud shaved off two full minutes at no extra cost:
What we really like
You can build it with stuff you may have around your house right now. All you need is some HVAC filters, a box fan, cardboard and some duct tape.
You get a CADR estimated at around 274 CFM for around $85. It offers the same (and better!) air cleaning performance as much more expensive shop-bought devices such as the Mila (35 mins), the Austin Air HealthMate HM400 (37 minutes) and the PuroAir 240 (48 minutes).
What we think could be better
It takes up a ton of floor space. As you are looking for a device for a large space, this shouldnโt be a massive issue but you need to be aware of it. This unit uses 20x20x1 MERV 13 filters, so when made into a box, it will be pretty big.
It runs quite loud. When running at its top fan speed, our CR box hit 60.7 dB(A), and there is no way to adjust this as it is the only speed available after removing the dial to add the cardboard shroud.
So, for those wanting to build an air purifier suitable for large spaces with stuff they have around the house (or spending less than $100), then the Corsi-Rosenthal box is the best option.
Other units we tested but donโt recommend for large rooms
Austin Air HealthMate– A large, robust, American-made air purifier containing a filter packed with 15 lbs of activated carbon for dealing with VOCs. However, it didnโt have the cleaning power that we expected from a unit of this size. Our air cleaning performance test results show that it needed 37 minutes to clear all PM1 pollutants from the air in our small 728 cubic ft. test room โ that is nearly the same amount of time it took the Levoit Core 300, which is a small device that you can place on the kitchen counter.
Blueair Blue Pure 211+– This was a strong contender for our guide. Itโs powerful, comes with effective filters, looks really cool and is extremely easy to use. However, it didnโt make my list for one reason: you canโt disable its ionizer. I wrote about ionizer technology in depth here, but studies show that ionization produces harmful by-products, such as ozone and nitric oxide, that are not only harmful with people with respiratory conditions but can also interact with common household chemicals to generate new ultrafine particles.
PuroAir HEPA 14 240– Despitethe manufacturers’ bold claims, the PuroAir 240 simply doesnโt clean the air effectively in large spaces. This air purifier needed 48 minutes to clear all PM1 particles from the air in our small test room, so it would take hours to clean the air of a large space. Plus, considering it’s priced at $159, this is an expensive device for this level of air cleaning power.
Wrapping up
Before we close this article, I want to talk about very large spacesโthose close to 1000 sqft.
When youโre trying to find a solution for spaces this large, you will find that even the Smart Air Blast Mini will not be powerful enough to provide enough air changes per hour. Now, Smart Air does offer a large device called Blast, which is good for spaces of 1,300 sq. ft. and costs $929.
But you also have the option of using multiple devices.
To work out the total power of multiple devices, all you need to do is just add their CADR together.
1 x CleanAirKits Luggable XL-7 = 323 CFM
2 x CleanAirKits Luggable XL-7 = 646 CFM
A total CADR of 646 CFM is good for five5 air changes in spaces up to 970 sq. ft.
1 x AirFanta 3Pro = 436 CFM
3 x AirFanta 3Pro = 1308 CFM
A total CADR of 1308 CFM is good for five5 air changes in spaces up to 1960 sq. ft.
You can use our CADR calculator to figure out how much CADR you need depending on the size of the room:
I hope you find what you’re looking for among the air purifiers I chose for large spaces. As always, let me know in the comments if you have any questions. Or email me directly if you need help finding a device that works for your specific situation.
AROEVE doesn’t make it easy to find out much about the company: their website is empty of information and there arenโt 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:
However, they are all very positive, making me think that many of these โreviewersโ 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.

The lowdown on the AROEVE MK01
โNo filter costs but it failed to deliver when it came to cleaning the air in my home..โ
โ Danny Ashton, HouseFresh Founder & Senior Writer
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
Itโs 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 donโt think they help with the air cleaning!
What we think could be better
AROEVE doesnโt share the CADR score for this air purifier and thatโs likely because itโs 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.
The MK01 has simple controls with no app or auto mode. You can choose a timer of 6, 12, and 24 hours.
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.
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.
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:
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 weโve tested. The test has three parts:
We introduce particulate pollutants into the room by using an incense stick
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
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 weโve 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, itโs 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
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, itโs far too high to recommend to most people.
Keep Your Money: Our filter uses uniquely adsorption reaction filtration technology, unlike the off-brand filter that imitates us on the market, we use environmentally friendly and healthy materials.
Prevent Clogging: When hairs, dander, and other large particles meet the pre-filter layer, they will be blocked outside to prevent the air purifier from clogging.
Special Reaction Filter Layer: Reaction filter layer can react with harmful particles entering the filter and produce harmless substances. We use a unique production process that is unmatched by the rest of the filters.
Impressive Filtration: Impressive filter layer is used, which It can filter airborne such as smoke pollen dander hair smell. Improving air quality and promoting better health and well-being for you.
Removes Unpleasant Odors: The premium reaction filter layer physically absorbs unwanted odors and fumes such as smoke, cooking odors, and pet odors, as well as VOCs, which makes it a good choice for homes with pets, cooking, and smokers.
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 MK01โs adjusted score is 3 stars, due to the evidence of review manipulation.
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.

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.
Blueair is well known in the world of air purifiers as theyโve 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 doesnโt have the features and extras you get in their premium ranges.
As I always like to clarify, we donโt 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
โIf you donโt 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
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.
Simple is the name of the game with the Blueair Blue Pure 311 Auto. The control panel canโt 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.
Pressing the button again, you can adjust the speed with three options. Press the same button again and it switches off. Itโs 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.
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:
The 311 Auto is the middle-sized unit in Blueairโs 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:
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).
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.
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:
From that point, the air moves through the activated carbon layer, which removes odors from pets, cooking and smoking.
The HEPA filter will need replacing around every six months (the filter replacement indicator will let you know when), but donโt worry; itโs super easy to do so.
Follow these step-by-step instructions:
Unplug your 311 from the outlet
Twist the top of the unit (the white bit) until you feel it unattached from the body, and remove
Peel the velcro from the pre-filter and pull it from the HEPA filter
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.
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+.
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.

We calculated the monthly energy consumption costs with the help of the Department of Energyโs appliance energy calculator. We calculated yearly costs associated with running Blueair Blue Pure 311 Auto for 24hs a day for 365 days. We chose to run this calculation utilizing the U.S. average utility rate of $0.12/kWh as of the 1st of May, 2023.
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.
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 HEPAsilentโข 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.
Weโre 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+
โA 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 donโt want something that will create a lot of noise.โ
โ Danny Ashton, Founder & Senior Writer
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
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 itโs still a good-looking machine, even without the 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.
I particularly liked the magnetic cord straightener as itโs a convenient way to ensure the cable remains tidy and in place.
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):
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.
Comparing cleaning performance and energy usage, itโs clear that the HEPASilent filter fulfills its promise of cleaning the air quietly.
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.
As with all HEPA filters, they need replacing periodically when the fibers become complete with trapped particles. You wonโt have to mark it on your calendar though; the 411+ will tell you when itโs time with a glowing red light.
When the time comes, follow these simple steps:
Unplug your 411+ and turn it upside down
Twist the cap off to reveal the filter inside
Use the tabs to pull the filter out of the unit
Insert the new filter, replace the cap and plug your 411+ in
๐ก Pro Tip: When youโre 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 itโs 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.
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 donโt mind going for generic filters, you can find them for $10 per filter.
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.
If you have a small room and donโt want to generate too much noise, the Blueair 411+ is well worth considering.
We calculated yearly costs associated with running the Blueair Blue Pure 411+ 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.
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.

I didn’t sit down to write this review until AFTER we conducted all these tests. You can rest assured I will tell you if this is not a unit you should buy.
The lowdown on the Pure Enrichment PureZone Mini
“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
If you donโt 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 itโs 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 wonโt blow you away, with a CADR score of only 10 CFM.

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.
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.
โ ๏ธ Unfortunately, the handle came off a few times, leading to the unit falling to the floor. Luckily, the air purifier didnโt 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.
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.
Personally, I like the look of the QT3 but thatโs 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.
The PureZone Mini portable air purifier is very simple, with just one button that switches it on and three selectable speed modes.
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 youโre 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.
Letโs talk filters: True HEPA with activated charcoal
The PureZone Mini comes with a solid HEPA filter and a small amount of activated carbon. Itโs not bad for filtering the air from particle pollution but it would be useless against VOCs.
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.
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.
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:
โ ๏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 โclean 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. Thatโs 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.
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.
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.
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.

Hitting the open road in your RV is guaranteed to be a fun-filled adventure. But as well as collecting memories on your travels, youโll also bring some pretty polluted air on board.
This may sound at odds with the pristine air you often find in nature. However, inside your RV, you will commonly find particulate matter from traffic fumes and road dust, harmful VOCs emitted by gas stoves and may even face nature’s nastier side in wildfire smoke and allergies. Not to mention the stale smells that can occur if you have the whole family along for the ride.
Gas stoves emit nitrogen dioxide that irritates the lungs. Studies show that children exposed to VOCs created by such cookers are 42% more likely to develop asthma.
You are most exposed to harmful air pollution when traveling in a vehicle. Although RVโs will have an air filter, these struggle to keep exhaust fumes such as carbon monoxide and PM2.5 such as road dust out of the cabin. While rolling down your window increases your exposure by 80%.
Cooking, cleaning and even breathing contribute to excess moisture inside your RV, meaning mold can quickly become an issue. Inhaling mold particles can cause allergy-like symptoms, including stuffy nose, wheezing and itchy eyes and skin.
Being closer to nature can result in greater exposure to allergens. Pollen particles typically range between 2.5 and 25 microns, which can enter the respiratory system and seriously affect your vacation.
Wildfires are getting worse, affecting further reaches of the country for longer periods of time. This means you can quickly become exposed to harmful particulates when traveling in your RV during the spring and summer.
Remember that all of these harmful pollutants will be exemplified in the confined space of your RV. The EPA has conducted numerous studies that show indoor air pollution is 2-5 times worse than what we find outdoors, as pollutants become trapped and concentrated inside.
Itโs simple to remove these pollutants by using an air purifier to capture the most minuscule particles and allow you to enjoy your vacation without the threat of toxic air.
Youโll also benefit from being able to invest in a more compact (and cheaper) unit, as cleaning the air in an RV is much easier than in a traditional home.
In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
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.
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.
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.
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.
We track sound levels emitted by the air purifier at different fan speeds with the help of a commercial sound meter.
With our test data in hand, I was then able to select seven of the best air purifiers on the market that will help transform the air in your RV.
Staff Picks: The top 3 air purifiers for RVs
If youโre in a hurry to hit the road, here are our three top picks, allowing you to find a speedy solution to your air quality concerns.
Last update on 2026-04-04 / Affiliate links / Images from Amazon Product Advertising API
Whether you travel in a Tiny Home campervan or a house-on-wheels RV, your space can quickly turn from sanctuary to cesspit if you ignore your air quality. With all recreational vehicles being different, assessing your options to find the right purifier is essential.
Check out the complete list below to see various options suited to varying-sized spaces, styles and budgets.
The IQAir Atem eclipsed other portable units during our tests, clearing all traces of PM1 particles 10 minutes faster than the next best unit. Powered by a decent fan that achieves an airflow of 39 CFM and IQAirโs outstanding HyperHEPA Plus filter technology.
These filters can remove 99% of the smallest PM and gas particles. This means everything from exhaust fumes to road dust will be removed from your RV. Despite being a portable unit, the filter also comes with a 1-year lifespan โ the longest-lasting filter on this list.
This option looks sleek, and IQAir has clearly thought about how this unit will be used in a vehicle. You can simply sit it atop a surface inside your RV’s living quarters or attach it to the cabin’s headrest for targeted protection while you drive. Even the way you power this unit is geared toward RVs, connecting to the 12V DC adapter in your vehicle while drawing a minimal 3.4 watts at its highest speed.
What we really like
Rapid particulate removal for a portable air purifier
High quality, HEPA-certified filters
DC power makes it ideal for use on the road
The app is a valuable addition, offering enhanced controls even when youโre not near the purifier
What we think could be better
The controls are less responsive, but the app makes up for it
It will be out of many people’s budget
The downside is that you have to pay a lot more for this performance than elsewhere on the market. At $400, this is undoubtedly a premium option that may not appeal to all RV users.

With a higher rate of airflow, you can expect to eradicate harmful particulates and gasses found when traveling in an RV in record speed. Using Levoit’s hallmark 3-stage filtration, you can breathe easy knowing that all the common RV pollutants will be taken care of. From road dust to exhaust fumes and even the stinky odors that accumulate when vacationing with the whole family.
What we really like
It can clean a large area of all pollutants in an hour
More compact than the 300S for those tight on space
On sleep mode, it makes just 24 dB, allowing for round-the-clock protection
Low energy draw is ideal for solar or leisure battery use
What we think could be better
It requires to be plugged into the mains electricity
No on-board air sensor for real-time feedback or Auto mode
When we assess the CADR to $ ratio on offer from the 200S, it is seriously a shrewd investment. Add this to the fact you can also connect the purifier to a smartspeaker or the VeSync app and it really feels like a bargain.
You won’t find an in-built air sensor nor see the same speedy results as the more powerful 300S. However, you will notice a lower power draw, which is preferable when running on limited electricity and enjoy a more compact design that will slot into a medium-sized RV without stealing too much living space.

This increase in performance is evident when comparing test data with the ionizer-free Smart Air QT3. Despite the QT3 being a more powerful unit, they both cleared our Tesla of all pollutants in 47 minutes. An excellent time for both units.
Inside the 1804 is a HEPA filter to remove particulates and their patented NCCO (Nano Confined Catalytic Oxidation) reactor, which (much like activated carbon) removes VOCs and odors from the air in your RV.
Well designed to fit in a multitude of spaces in your RV without eating up much space
It comes with a built-in battery that can go on for up to eight hours
What we think could be better
NCCO filter means this might not be the best option for those with respiratory conditions
Only two fan speeds, which limits your response to changing pollutant levels
Thereโs no denying that the 1804 is an excellently designed air purifier. It comes with a modern aesthetic, a carry handle and a choice of four colors. Plus, its compact size means it will sit comfortably on a tabletop, nightstand, or even beside you in the cockpit as you go on your next adventure.
Another key feature that makes the Westinghouse excellent for use in an RV is its in-built battery. Providing enough juice for up to eight hours of pollutant-free air on a single charge.

For an air purifier that costs less than $40, Iโm not going to tell you this option will change your life. But for car campers, campervans or targeted use in small areas like the driverโs cabin, you will benefit from much cleaner air with this unit by your side.
Thatโs because this unit uses HEPA filters that are guaranteed to remove particles like road dust. Whatโs more, it comes with an activated carbon-impregnated pre-filter that will even take the edge off those unpleasant smells that all too often arise in an RV.

It took a long time to bring pollutant levels down to zero
It is quite underpowered in comparison to the other units on this list
The PureZone mini is also a doddle to use. It has a simple one-button control panel to select from its three fan speed options. It weighs less than 1 lb and will fit right into your luggage. Thereโs a nifty carry handle and its lithium-ion battery can last up to 12 hours before you need to put it back on charge.
Youโll also notice that this is the quietest option on the list, meaning it won’t distract you when sleeping, working or listening to your favorite road trip playlist.

7. An option including essential oils diffuser: Levoit Core Mini
The smallest Levoit air purifier in the Core line, the Mini is perfectly sized to fit into your RV without eating up precious floor space.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
The Levoit Core Mini proves that good things can come in small packages. Despite being the cheapest air purifier from the brand, it still shares the same technology as their high-end units.
Youโll find VortexAirโข technology, which pulls in air from 360 degrees, leaving no corner of your RV safe for pollutants to lurk in. As well as Levoit’s 3-stage filter that tackles the smallest dust, pollen and smoke particles, along with combatting odor and VOCs.
What we really like
Only air purifier to include an essential oil feature
Super compact, so wonโt take up too much space in your RV
Low energy draw is ideal when you only have limited power supply
It comes with Levoitโs excellent 3-stage filters
What we think could be better
Fairly low CADR for a mains-powered unit
I think it would struggle to clean the air in the advertised 178 sq. ft. space
Levoit decided to forego smart features and stick to a simple one-touch operation with three fan speeds on this unit. This makes operation simple and helps keep costs below $50, which is ideal for a unit used in an RV.
The Core Mini also has a secret weapon up its sleeve that will help with the stale and stinky smells that can overwhelm an RV. An essential oil tray on the side of the unit allows you to add your favorite fragrance and banish bad odor from your home on wheels.
What to look for when buying an air purifier for your RV
RVs are homes on wheels and with that come all the pollutants we find daily in our properties. With everyone sharing the same space, cooking dinner, sleeping and using the bathroom, pollutants can quickly build up. Not to mention the added exposure to traffic fumes, road dust and allergies you experience when traveling in a vehicle.
To find the right air purifier for your RV, consider these five key features that will help protect you when out on the road.
1. Does the air purifier utilize quality filters?
An air purifier is only as good as its filter technology. While varying forms are cropping up in newer appliances, the best (and safest) bet is to opt for mechanical filters that capture particles as they pass through the unit.
HEPA and Activated Carbon filters are peer-reviewed and proven to work. The HEPA stamp of approval indicates that a purifier can capture at least 99.97% of polluting particles as small as 0.3 microns, making it the ideal choice for the range of particles youโll encounter inside your RV.
Itโs worth noting that Levoit recently changed the terminology of their filters from H13 HEPA to simply a primary filter. While this would usually set off alarm bells, we are confident that Levoit air purifiers can still capture the tiniest particles, as weโve experienced it firsthand during our hands-on reviews.
2. Can the purifier clean the air effectively inside your RV?
Each purifier is designed to work in a specific sized room, so youโll need to measure your space and compare it to different unit’s suggested room sizes.
Youโll want to find a unit capable of completing at least four air changes per hour (ACH). This means intaking, cleaning and redistributing the air from your whole RV four times over to ensure it is free from pollutants.
Having recently spent my vacation in a classic VW Campervan, I know that to achieve 4.8 air changes per hour, the minimum power an air purifier needs is 19.55 CFM.
Those of you with larger vehicles will need more powerful units, so be sure to measure up and use our CFM Calculator below.
3. How much energy does the purifier use?
You may be relying on a limited power supply when on the road. So the last thing youโll want to do is drain your solar or leisure battery or only be able to utilize the purifier when connected to an electrical hookup.
By opting for an air purifier that draws minimal energy, you can preserve your power supply while keeping your air fresh for longer.
Alternatively, looking for rechargeable options with internal power sources will pay dividends for those seeking a more off-grid RV experience.
Such units include the Smart Air QT3, Westinghouse 1804 and Pure Enrichment PureZone Mini, while the IQAir Atem utilizes the in-cabin 12V power supply. Bear in mind that the Levoit Core Mini, 200S and 300S require a traditional power supply as these units are more powerful than their portable alternatives.
4. Will the air purifier get in the way?
Space is always in short supply when spending time in an RV.
Assess where the air purifier would work best in your RV. Youโll want to keep it near to where you spend the most time (i.e., the bed or driving cabin) or as close as possible to any known pollutant sources. This will give you a good idea of how much space you have to spare and what size purifier you can purchase.
Opting for a smaller air purifier that can fit neatly on the worktop or shelf is a logical choice, but remember not to purchase an underpowered unit.
Each purifier will also make varying sound levels, so if youโre a light sleeper, will be working while traveling or simply enjoy the sound of silence, itโs best to know what you’re letting yourself in for before you take the plunge. Many manufacturers are now developing quieter and quieter appliances, with technology such as Levoits QuietKEAP keeping volumes as minimal as possible.
Tip
To find a purifier’s decibel range, check out our Specs and Features table for each option or consult the manufacturer.
5. Will you benefit from any additional features?
Air purifiers are increasingly offering new and innovative ways to make cleaning the air simpler. Smart features such as Auto or Eco modes monitor the air and adjust the fan speeds to respond to the current air quality levels, while Smartspearker or App connectivity allows you greater control, even when you’re away from the appliance.
Some units also combine technologies, offering two devices in one, such as fans, heaters and humidity control. This can be particularly beneficial in an RV, with interchangeable weather conditions and often issues surrounding excess moisture.
Common questions about air purifiers for RVs
The best way to improve air quality is to reduce exposure to pollutants. This might mean avoiding driving at peak traffic hours, steering clear of dusty backcountry roads or keeping on top of RV cleaning chores.
While you can throw open your windows and doors when parked up and away from pollutant sources, doing so while driving will increase particle levels substantially.
Using an air purifier in your RV is a failsafe approach to improving air quality, as it captures all particles, from pollen to dust to mold, wherever you are in the world.
Air purifiers work really well inside an RV as they can circulate air more effectively in a compact single-room space (compared to a house or apartment). More air changes mean far fewer pollutants, even when the source is prevalent at the time.
Remember that air purifiers require electricity to operate, so be sure to consider how you will power the unit before making a purchase.
How you power an air purifier depends on the individual unit.
Traditional air purifiers used in a home setting will connect to a power socket like any other appliance. These can still be used in an RV if you have the correct power supply or will stay at RV parks or campgrounds with electrical hookups. Such units include the Lvoit Core 300S and Core 200S, which make great additions to larger RVs that require more powerful fan speeds.
Portable or personal air purifiers usually have an in-built power supply. Units like the Smart Air QT3 can be charged at home and used on the road without electricity. Purifiers such as the IQAir Atem have special power adapters to use in your vehicle – reducing the risk of running out of juice.
The Levoit Core 300S offers the best protection from a wide range of pollutants for those with access to mains electricity. Itโs the most powerful personal air purifier on this list and is ideal for larger RVs with multiple occupants.
For those without the luxury of a full electric hookup, the IQAir Atem is your best choice. This portable air purifier boasts the highest CADR score, allowing for rapid removal of pollutants from your RV.
Wrapping up
Whether you love getting away for the weekend or are a full-time van lifer, paying close attention to the air you breathe on the road is essential. Remember that when residing in a vehicle, youโll face all the same pollutants in the home but with added traffic, dust and allergen concerns.
Opt for a quality purifier with quality filters to combat harmful particles. Combining HEPA and Activated Carbon filters will provide you with the best protection. To see a real difference in your air quality, measure your RV and find a suitably powerful option. Otherwise, youโll lose precious RV space and energy without seeing the benefit.
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.
Richard Taylorโs 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, itโs 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.
โThe 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
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.
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.
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.
The top of the device is flat and can make a handy side table:
With a body made out of metal and a MASSIVE filter, this is a heavy air purifier that weighs 47 lbs (21.3 kg).
Luckily, it comes on wheels that make it easy to move around the house.
โWith 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.
Filtration technology
The Austin Air HealthMate comes with a True HEPA filter and 15 lbs of carbon + zeolite mix.
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.
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:
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.
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:

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.
Speed
Sound Level
1
42.0 dB
2
53.2 dB
3
61.5 dB
This is how this compares to other devices we tested:
AIR PURIFIER MODEL

61.2 dB
28 minutes
Austin Air HealthMate HM400
61.5 dB
52 minutes
AirDoctor 3000

20 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 itโs 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 speed
Energy consumed
1
61.1 watts
2
85.05 watts
3
147.6 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:

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 canโt 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.
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.

We calculated yearly costs associated with running the Austin Air Health Mate 24 hours a day, 365 days per year utilizing the appliance electricity consumption calculator from the U.S. Department of Energy as of January 2025.
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. Itโs also in the same price range as the Core Mini, so it will be interesting to see how the LV-H128โs 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
โThe 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, itโs 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.
As you can see below, compared to the Core 300 and 200S, the LV-H128 is much smaller in height and floor space required.
Additionally, the unit has a dedicated aromatherapy slot on the top corner, which has a sponge that soaks up essential oils.
As clean air flows out of the air purifier, it passes through the oil-soaked sponge and diffuses the scent into the room.
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?
The LV-H128 features Levoitโs 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
It’s worth mentioning that the third layer doesn’t contain enough carbon to remove odors, so the LV-H128 isnโt a unit I would recommend for those with issues with odors or gasses.
โ ๏ธ Most new air purifiers come with the HEPA filter covered in plastic. Remove it before you start the unit; otherwise, it wonโt 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.
Itโs 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-128โs 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. Thatโs a much better choice for most people.
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.
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. Itโs more expensive to buy, but will be far more effective at cleaning the air and has similar long-term costs to the LV-H128.
SOURCES
We calculated yearly costs associated with running the Levoit LVโH128 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.
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 โfan + 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
โA 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
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.

Blueair knows that design is super important to their customers. They have been continually investing in this over the past few years. Iโm 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.
Its cube shape makes it easy to use in many places around the home, and doesnโt even need to sit directly on the floor.
The legs look like something from a high-end piece of furniture and even the fan holes’ design is aesthetically pleasing.
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 thatโs 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.
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 doesnโt 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.
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.
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.
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.
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.
โ ๏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 donโt 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 donโt 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.
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 average
0.74 m/s
2.61 m/s
Minimum total
0.51 m/s
2.26 m/s
Maximum total
0.99 m/s
2.91 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 itโs 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.
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.
If youโre 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.

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.
Theyโre 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 donโt 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
โA powerful air purifier for the budget, but I would still prefer the slightly bigger AP003 model.โ
If you donโt 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 youโd 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.

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.
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, youโll 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.
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.
๐ก At the top is a lock button that disables the deviceโs 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:
If youโre 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:
Industry-grade air filtration system
I love that the TaoTronics AP005 uses industry-grade H13 True HEPA and Activated Carbon filters that donโt produce harmful by-products like ozone โค๏ธ.
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 youโre good to go.
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.
โ ๏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 wonโt 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.
๐ต 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 didnโt 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 weโve 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, youโll 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.
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 VOCโs
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.
Itโs 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.
But if you just want to remove particles and donโt have a big budget to spend, you canโt go wrong with the TaoTronics AP005.

Here are five things you should do regularly to remove dog smells throughout your home.
1. Use enzymatic cleaners
You can use these on upholstery, carpets and fabrics and clothing. The enzymes break down the molecules that create odors and can eradicate dog smells without leaving harsh chemicals or fragrances behind, making them safe to use around both pets and children.
The cleaners come in both spray and liquid forms and you can buy them at most major stores.
Step 1: Spray or pour the liquid cleaner onto the affected area Step 2: Let it sit for a few minutes Step 3: Wipe the area clean with a damp cloth
2. Vacuum with a HEPA device
While your dog may not be too keen on the sight and sound of the vacuum cleaner, itโs essential to hoover carpets and rugs frequently. Devices that use a HEPA (High-Efficiency Particulate Air) filter are the most effective for eliminating odors. This is because they capture dog fur, dander and odor particles rather than recirculate them back into the air like regular vacuums.
Alongside rugs and carpets, don’t neglect other areas in your home, such as curtains and furniture. Anything that can be vacuumed should be.
3. Sweep and mop floors
If you have wood, laminate or tile floors, give them a good sweep to remove dirt and dust and then get to work with your mop. But before you reach for the store-bought floor cleaner, consider using vinegar instead. Due to its high acidic content, vinegar is excellent for breaking down and neutralizing odor particles, thus obliterating dog smells.
Step 1: Mix ยฝ cup of vinegar with 1 gallon of warm water for the solution Step 2: After each dip in the bucket, ring out the mop thoroughly and let the floors air dry when finished
4. Freshen up with baking soda
The various chemicals within the soda neutralize and absorb other smells. Unlike vinegar, which has its own pungent smell, baking soda is odorless.
Step 1: Sprinkle baking soda onto your carpets Step 2: Let it sit for a few minutes Step 3: Vacuum it up
๐ก You can also pour baking soda into shallow bowls and place these around areas of your home.
5. Wash your dogโs bedding and toys
A dogโs bed is often a significant odor source due to all that fur, dander and saliva. And when their saliva gets all over their toys, the odor can permeate your home.
Step 1: Shake out the bedding to remove as many hairs as possible Step 2: Place both the bedding and toys in the wash โ you can add half a cup of white vinegar to your usual detergent to eliminate smells Step 3: Hang the bedding to dry
Why does my house smell of dog? (and how to prevent it)
Now, let’s look at the potential causes of that dog smell and how you can fix each one.
Odor Cause 1: Poor hygiene
If your dog gets wet from the rain or has rolled about in muddy patches and puddles, this can lead to a very pungent โwet dog smell.โ When your dogโs coat gets wet, microorganisms in dog hair effectively break free as the water evaporates. Waste products in the dogโs skin, like bacteria and yeast, fill your home with odors.
Equally, some dogsโ fur can become matted with dirt and bacteria, causing unpleasant smells.
Step 1: Gently coax or place your dog carefully in the tub (you might need a treat to encourage them) Step 2: Dilute the special dog shampoo by adding some to a bowl full of water Step 3: Check the water is warm, then wet your dog Step 4: Shampoo your dog twice. The first time removes dirt and the second means you can properly wash their skin Step 5: Ensure you clean areas like the pads of their feet, armpits and stomachs Step 6: Next, use the dog conditioner. Be sure to leave it on for a few minutes before rinsing away Step 7: Give your dog another rinse to ensure no soap is left on their fur Step 8: Dry them thoroughly with a towel and blower
Odor Cause 2: Skin infections
If you notice that your hand smells after stroking the dog, their skin could be to blame. Microbes, including bacteria and yeast, cover the skin and injury or disease can affect the skin’s natural barrier, leading to smelly infections. Skin infections can also result from poor hygiene, so bathing regularly, as described above, will help.
Chafing is another cause of odors and often affects parts of the dog where thereโs enfolded skin. For example, skin folds on their face, particularly the ears and body, such as the feet, anus and vulva.
Be sure to check, clean and dry these areas regularly and notice if the skin looks inflamed or sore. You might need to visit the vet if you spot blemishes or if your dog’s skin is itchy and uncomfortable.
Odor Cause 3: Ear infections
Dog ears are often warm, moist environments, yet certain breeds may be more prone to problems. For example, Springer Spaniels and Basset Hounds have notably hairy and floppy ears. This could make them more susceptible to ear infections, commonly caused by increased bacteria and yeast.
Similarly, if your dog has allergies or experiences hormonal imbalances, this can create a bacterial surge, leading to a toxic smell.
If you suspect your dog might have an ear infection, be sure to visit your vet.
โ Do not attempt to put anything inside the ear; this can be dangerous if the eardrum is damaged.
Odor Cause 4: Bad breath
Poor dental health is often the cause of bad breath, particularly the build-up of tartar and plaque. All mouths contain bacteria, but when plaque and tartar form on the teeth, the bacteria rise. Dental infections can then occur, which results in a putrid smell.Hair and food can also get caught in the tartar and inflamed gums, exacerbating the stench.
An underlying condition or disease can sometimes cause strong doggy breath, so visit your vet if youโre worried.
Brushing your dogโs teeth is the best way to prevent plaque formation.Use suitable canine toothpaste, and toothbrushes and brush daily (or at least weekly).
Odor Cause 5: Flatulence and poor diet
As much as we love them, dogs can be pretty disgusting regarding some of the things they consume. They can also eat very quickly, which may trigger digestive issues. Usually, however, if they ingest rotten food, any flatulence (aka farting) will be temporary. But the odor can still be a real problem.
Avoid letting your dog scavenge and feed them a plain, easily digestible diet to ease flatulence. If it continues, visit your vet if they have an underlying condition affecting their digestion.
Encourage your dog to eat more slowly using a food mat or dispensing toy.
Odor Cause 6: Anal glands
The anal glands are a natural part of your dogโs anatomy and are two tiny sacs on both sides of the rectum. They fill with pheromones to mark your dogโs territory and then empty again when the dog passes feces. However, they can become impacted and infected if they don’t empty.
Itโs not just a terrible smell youโll notice because the dog will probably also be very uncomfortable, dragging their bottom on the floor and scratching and licking their anus.
Visityour vet as soon as possible, as they can empty the anal glands. A higher fiber diet or fiber supplement can also help prevent this problem in the long term.
Can air purifiers ged rid of dog odors?
In a word: Yes.
The best air purifiers can sanitize the air inside your home while eliminating odors like dog smells. However, choosing a device with both a HEPA filter (just like with a vacuum) and an activated carbon filter is essential.
The HEPA can capture and trap tiny, airborne particles like pet dander, while the activated carbon (sometimes called charcoal) removes smells. The latter uses adsorption, meaning that odor particles stick to the carbon. Note that the more activated carbon a filter contains, the better it will be at removing odors.
The top 3 air purifiers for dog smells
Weโve tested many air purifiers at HouseFresh. We have our own testing room, which we fill with incense smoke and track how fast and effectively the purifier cleans the air.

Final thoughts
Itโs important to know what might be causing dog smells, and sometimes there can be a serious cause. Generally, however, simple things like regular bathing and teeth brushing can solve the problem.
If dog smells are a particular issue in your house, you can do many things to eliminate the odor. On top of methods such as vacuuming and utilizing vinegar and baking soda, an air purifier is one of the most effective ways to eliminate smells.
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. Itโs 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 donโt need a Ph.D. to understand.ย
How we test air purifiers
Read our full testing methodology.
Using the above process, we can compare units like for like instead of just scoring them based on manufacturer data.
Intro out of the way, letโs get on with this review, shall we?
The lowdown on the Levoit LV-H132
โIt 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
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.
You will notice that the third button shows an icon for the HEPA filters. This will turn on when itโs 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.
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 wonโt be as powerful as other Levoit units when dealing with pollutants. That said, it gets the job done.
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-H132โs carbon filter uses activated pellets โ better than many other budget units that use impregnated fabric.
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 itโs 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, itโs 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 wonโt 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, itโs 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 doesnโt 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.
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 wouldโve 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.
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 Energyโs appliance energy calculator to calculate yearly costs associated with running the Levo LVโH132 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.
Moving away from home can be an exciting experience, but living in close quarters with one or more roommates can be a daunting experience.
As you prepare to get your first taste of independent living, it makes sense to consider bringing an air purifier with you to fend off unwanted smells and protect your personal space from the dreaded freshman plague rife on campus, ready to strike against weary students.
The right air purifier will draw in air from your dorm and pass it through a series of filters that capture dust, pollen, smoke, odors and viruses. What’s left behind is clean, fresh air that will be redistributed into the space.
In this article, I shortlisted a handful of budget-friendly air purifiers that will not take up a lot of space but that are powerful enough to actually make a difference. We bought each device on this list with our own money so that we could run our usual battery of tests to assess their air cleaning performance, noise levels generated, energy consumption, yearly running costs and long-term user experience.
How we test air purifiers
Read our full testing methodology.
If you donโt have time to read my full article, check out the table below for a quick TL;DR of all the air purifiers I recommend for dorm rooms:
1. Best air purifier for small dorm rooms: Winix A231 (or A230)
Our top pick for dorm rooms no larger than 231 sq. ft. is a small air purifier with no smart features that you can find for less than $80.
Before I tell you more about this device, let me clarify that I’m writing here about the A231 because that is the model I tested: the white and grey device you can see in our photos. But if you prefer black, you can instead get the Winix A230, which is exactly the same as the A231 but in all black. Both devices have the exactly same internals, so it’s just a matter of taste. Right, with that info out of the way, let me tell you more about this unit.
If you are looking for a small air purifier you can have beside your bed or, on a narrow window sill or on top your desk, then the Winix A231 might be just what you want. With a CADR of 154 cfm, the Winix A231 can provide five air changes per hour in dorm rooms up to 231 sq. ft. thanks to a powerful fan and a high quality True HEPA filter packed with activated carbon. This combination allows the A231 to tackle both particles and gases, removing everything from dust to unwanted odors.
What we really like
It is small and compact, so it won’t take up too much space.
It cleaned our test room of PM1 pollutants in 40 minutes, which is 14 minutes faster than the similarly priced Levoit Core 300.
You can expect to spend $49.99 per year in filter replacements if you choose OEM filters, which is cheaper than most small air purifiers.
There are generic filters available on Amazon, which would bring long-term filter replacement costs down to under $20 per year.
What we think could be better
As with most small air purifiers, it can get loud at its top fan speed, reaching 57.9 dB, which will be too loud for some โ especially if you need to study.
If it loses power, the A231 will go back to default, with PlasmaWave enabled.
The Winix A231 comes with an inbuilt air quality sensor, so you get an auto-mode that will kick in autonomously as soon as the sensor detects pollutants in the air. This can come in handy if you want to set your air purifier and forget it. And, as with other Winix air purifiers, the A231 comes with PlasmaWave bipolar ionizer technology but you can disable it if you have concerns about ionization and ozone.
With a CADR of 430 cfm, the 3Pro can clean the air in larger dorm rooms (up to 671 sq. ft.) for just $175.99 if you go for the HEPA + carbon version.
Use the discount code HOUSEFRESH for 5% off when buying directly from AirFanta.
The AirFanta 3Pro is part of a new generation of air purifiers that are powered by PC fans, which make them a lot quieter and more energy efficient than traditional devices you will find at a retail store. The design of the 3Pro is inspired by a popular DIY air purifier you might have heard of called the Corsi-Rosenthal Box, with a base around which you get four filters that are topped with four PC fans which create the perfect cube.
The 3Pro is one of the most powerful air purifiers I have tested and it truly blew my mind in 2024, becoming one of our top recommendations. If you are looking for a relatively compact device (12.6 x inches, or 32 x 32 cm) that you can assemble yourself (and disassemble, when the time comes to go back home or move to a new place), then read on as the AirFanta 3Pro might be just what you’ve been looking for.
What we really like
It offers excellent value โ it has an estimated CADR of 430 cfm and you can buy it for $160-$175, whereas most air purifiers this powerful will cost you more than $500.
You can assemble it and disassemble it in just a couple of minutes, so you can take it with you wherever you go inside a small suitcase or big backpack.
It is relatively quiet considering its outstanding air cleaning power, hitting 56 dB at top speed.
Amazing performance, cleaning our test room in 17 minutes โ this is just two minutes slower than the much bigger and much more expensive Smart Air Blast Mini, which is a popular air purifier used in classrooms and offices.
What we think could be better
It is often out of stock on Amazon, but you should be able to find it on the official AirFanta store. By the way, when buying directly from AirFanta, you will get a 5% off when using the discount code HOUSEFRESH.
It is much louder (56.3 dBA) than other PC fan-powered air purifiers we have tested when running at full speed. Check out my CleanAirKits Luggable-XL review to see what I mean.
Traditional retail air purifiers come with a control panel at the top of the device with buttons or a screen for you to switch modes and fan speeds, but the AirFanta 3Pro doesn’t. Instead, you will get a 110-220v AC to 3-12v DC power adapter which will allow you to control the speed of the fans and the noise output.
Tip
We found that setting it to 6.54V is a sweet spot where the 3Pro offers excellent air cleaning while generating just 43dB, which is quieter than the recommended 45dB for classrooms โ a good sound level to keep it running in the back without it disturbing your sleep or study time.
The Vital 100s is a smart air purifier suitable for dorm rooms no larger than 219 sq. ft. with an on-board air quality sensor that connects to your smartphone for $139.99.
The Levoit Vital 100S has a dust CADR of 146, so this relatively small air purifier will be able to provide five air changes per hour in dorm rooms of up to 219 sq. ft. It comes with a removable pre-filter and a bonded main filter with a combination of activated carbon (to deal with odors and gases) and a HEPA-like particle filter (to filter out dust, pollen and other small particles).
If you are looking for a smart air purifier that you will be able to control and manage from your phone, then the Levoit Vital 100S is worthy of consideration. As with the Winix A231, the Vital 100S comes in an on-board air quality sensor that unlocks an auto-mode that will automatically adjust fan speeds based on the quality of your air. But it doesn’t stop there. You can also connect to your 100S from your smartphone through Levoit’s VeSync app, which is one of the most polished air purifier apps out there.
What we really like
It comes with a removable pre-filter that you can clean to extend the life of the main filter.
It comes with an auto-mode and app support, something rare in air purifiers selling for less than $200.
It is super energy efficient, with a max draw of 27.3 watts.
It comes with pelleted activated carbon for dealing with odors and gases, which is much better than the cheap impregnated fabric we see with air purifiers in this price range.
Weighting less than 7.5 lbs and measuring 6.4 x 12.8 x 16.1 in (or 16.3 x 32.5 x 40.8 cm), this is a relatively small air purifier that will fit most dorm rooms.
What we think could be better
The particle and the carbon filters are stuck together (a.k.a. bonded), so you will need to replace both of them even if the only one that needs replacing is the carbon filter (which usually runs out faster than the particle filter).
Levoit initially marketed the Vital 100S as having a HEPA filter but after Dyson complained to the BBB, they removed all mentions of HEPA without any explanation to the public. This doesn’t affect the performance of the 100S but it’s not a good look on Levoit.
The Levoit Vital 100S is the upgraded, smarter version of the older Vital 100 and the little sibling of the popular Vital 200S. The Vital 100S cleared our small 728 cubic feet test room of all PM1 particles in 37 minutes โ this is 11 minutes faster than the non-smart Vital 100 (48 minutes) and 17 minutes faster than the $99 Levoit Core 300 (54 minutes).

4. Best tabletop option: CleanAirKits Triple Exhalaron
Designed to be used as a table centerpiece, the Triple Exhalaron is a PC fan-powered air purifier with a CADR of 128 cfm that can be used in dorms no larger than 192 sq. ft.
The Triple Exhalaron is another PC fan-powered air purifier, this time manufactured by the team at CleanAirKits. The design of the Exhalaron is quite unique, with three cylindrical HEPA H10 filters (with activated carbon inside) that sit between a thin wooden base and a thick wooden top home to three CoolerMaster Mobius argb (2400 rpm) PC fans.
If you are looking for a small air purifier you can use in your dorm but also take with you to the library or bring to study groups, then look no further than the Triple Exhalaron from CleanAirKits as this is the only air purifier we have tested that has been designed from the ground up to be used as a table centerpiece ensuring it will reduce viral load.
What we really like
It is designed to be powered by a battery pack (with a male USBC pigtail), so you can take it with you around campus. You get up to 10 hours of use with a 20,000 mAh battery.
It is super quiet, ranging from 35.2 dB to 40.5 dB from its lowest to its highest fan speeds.
It looks pretty cool โ I know itโs a personal preference, but I really like the steampunk feel of the Exhalaron. Now, I know it won’t be everyone’s cup of tea.
What we think could be better
Initial price is much higher than all the other air purifiers on this list ($359.00).
Filter costs are higher but do last longer than cheaper Core series units โ up to 15 months
It has a CADR of 128 cfm, so it will be able to give you five air changes per hour in dorm rooms no larger than 192 sq. ft. This air purifier is super quiet, hitting just 40.5 dB when running at its top fan speed, while still being able to clean the air faster than popular small devices like the Levoit Core 300.
The Coway AP-1512HH is one of the most recommended air purifiers on the web, so you will probably have seen it if you’ve been doing your research for a while. This oldie but goodie will deliver five air changes per hour in dorm rooms of up to 360 sq. ft. thanks to its CADR of 240 cfm and its combination of a removable pre-filter, a True HEPA filter, a carbon impregnated filter and its bipolar ionizer (which you can disable if you prefer not to use). Filter replacement costs are some of the lowest we have seen.
The reason why I didn’t include it on this list is that in 2025, I think there are newer air purifiers that offer more value for a better upfront price. Plus, it is quite big and could be too bulky for small dorms. But if you like the look of it, or if you prefer to go with a device that has been on the market for over a decade, then the Coway Airmega AP-1512HH Mighty could be the best pick for you.
This small(ish) air purifier has a CADR of 185 cfm, making it a good choice for dorm rooms no larger than 277 sq. ft. It comes with H13 medical-grade HEPA filters that will be able to remove not just dust and pollen particles from the air but also bacteria and viruses. If odors and chemicals are an issue, you can buy the optional activated carbon filter, too.
This is a great air purifier on paper but I didn’t include it as one of my main picks because it generates nearly 60 decibels of noise at top speed (58.2 dB), which is likely to be too loud for a dorm where people are going to be studying and need quiet to concentrate.
But if you are looking for an air purifier that looks like a piece of furniture and are not too bothered by smart functions or loud noises, then the Smart Air S could be just the thing.
The Levoit Core 300S is the upgrade to the older, $99 Core 300, now sporting smart features such as smartphone connectivity and app support. The Core 300S is also more energy-efficient and much faster (45 minutes) at cleaning the air compared to its older counterpart (54 minutes), which is impressive considering it costs just $50 more.
It has a CADR of 141 cfm so it can clean the air five times per hour in dorm rooms as large as 211 sq. ft., and comes with a bonded filter including a pre-filter mesh, a particle filter and a layer of activated carbon. I chose to go with the Vital 100S instead of the Core 300S because it offers a higher CADR (146 cfm) for a lower price ($139.99).
But if you prefer a cylindrical design and want an air purifier that you will be able to manage from your phone, then the Levoit Core 300S might be the best option for you and your dorm room.
Other units we tested but donโt recommend for dorm rooms
Levoit Core Mini: In testing, this device took 1 hour and 53 minutes and had a CADR of 32 CFM, making it too small even for the smallest dorm rooms. You are better off saving up more and going for the bigger Core 200S or Core 300.
Medify MA-25: While this is cheap, the filter replacement costs were much higher than similar-performing units.
Blueair 411+ Auto: All Blueair air purifiers use a technology called HEPASilent, which uses an ionizer, but you canโt disable its use. The activated carbon used in these units is the fabric carbon, which we found far less effective than the pelleted carbon.
PuroAir 240: This is an air purifier that you will often find at the top of Amazon as a sponsored option but that doesn’t offer a good enough value for your money, based on the results of our performance tests.
What to look for in an air purifier for a dorm room
Sadly, many dorm rooms in America are in older buildings with poor ventilation, which can mean levels of indoor pollutants can quickly rise and cause problems.
Indoor air pollutants can cause health problems and can even affect grades; a study from Israel showed that those students who breathed in the air with a higher count of fine particles scored on average 2.3% lower. The EPA stated that children in classrooms in highly ventilated spaces perform better on standardized tests than children in poorly ventilated rooms.
To get the most from college, you must create a space in your dorm room free of tiny particle pollutants that have been shown to create health problems and reduced cognitive ability.
You should try to ventilate the dorm room as much as possible, but when this isnโt possible, an air purifier can do a great job of keeping the air clean of these tiny harm-causing particles.
But to get the right air purifier for a dorm, you need to consider the following:
1. Consider the size of your dorm room
The average dorm room in the United States measures around 228 square feet for a dorm room with two students. The good news is that smaller spaces need smaller air purifiers to be effective. Most air purifiers are given a CADR score that is used to give you an indication of an air purifier’s cleaning power. Higher CADR will allow you to keep a large space clean.
An average double-person dorm room of 228 square feet with an 8ft ceiling will need a CADR score of 145 CFM to provide the 4.8 air changes per hour that the EPA recommends for portable air cleaners. This is exactly the CADR of our number 1 pick, the Levoit Core 300.
You can use our CFM calculator to find out what CADR you need to clean the air in your dorm room at least four times per hour:
2. Look for activated carbon filtration if you worry about odors
Particle filters like HEPA or MERV are great for removing the tiny particles from the air in a dorm room but wonโt do anything about the odors that come with student living. An activated carbon filter can help to catch these odor gasses and keep the dorm room smelling better.
As a rule of thumb, you will want to choose an air purifier that uses pelleted carbon vs. the impregnated carbon fabric as we found that the latter will quickly lose effectiveness at removing odors.
3. Calculate long-term running costs
Most dorm rooms include free electricity usage. However, you will still need to replace the filters every six months for smaller air purifiers and potentially longer with larger devices.
We include the latest price for the genuine and generic filters for each recommended air purifier we review so you can know the accurate long-term running costs.
Tip
Be aware that running a large air purifier is often cheaper than you need as the filters are bigger and need replacing less often but often cost very similar.
4. Decide whether you need to get an air purifier with smart features
It feels like every appliance is smart nowadays, from your refrigerator to your television. It turns out that the same can be said for air purifiers.
The benefit of smart features is that they come with an onboard air quality sensor so that the air purifier will only kick in when it detects pollutants in the air. It is super useful for a kitchen but not mission-critical for a dorm room, so feel free to save money on a non-smart version.
But if budget is a concern, you can often find non-smart versions for cheaper prices. Sure, they won’t turn on and off automatically but you can simply keep the device running at a fan speed that you donโt find intrusive so it works all the time.
Why you should trust our recommendations
Unlike most guides to air purifiers you will come across on the internet, we actually put the air purifier we recommend through an in-depth testing process and share this data with our readers. We have reviewed over 90 air purifiers since 2020, and based on this original data, we have identified what we think are the best air purifiers suited for those living in dorm rooms.
We are 100% independent and don’t take review units in exchange for review; we pay retail like everyone else. This means we are free to say when an air purifier fails to deliver, and we don’t have any outside pressure to push certain brands or models.
If you still can’t find the right air purifier for your dorm room or just want to ask me more about our performance testing, please reach out to me directly danny@housefresh.com
PlasmaWave technology is a bipolar ionization process developed by Winix to boost the air cleaning capabilities of their air purifiers, while generating minimal levels of potentially harmful chemical byproducts like ozone.
But is this something you should be worried about?
The reason I ask is that most people become concerned about ozone generation upon reading the words โionizerโ or โionizationโ.
It is a valid concern, especially considering there have been a number of high-profile class action lawsuits involving ionizer air purifier models releasing ozone into the air to help remove pollutants. These lawsuits have led to very public bankruptcies of air purifier companies and even a blanket recommendation from Consumer Reports in 2003 to avoid ionizers altogether.
By 2010, all portable air purifiers sold in California had to be certified by the California Air Resources Board after being tested for ozone emissions to ensure devices meet the ozone emission concentration limit of 0.050 parts per million (50 ppb).
All these events led to big changes in the way in which air purifier manufacturers design these devices.
The original ionizer air purifiers used high voltage to release negative oxygen ions that would attach themselves to mid-sized particles, forcing them to fall onto surfaces. The problem was that this process also produced high levels of ozone and could lead to other potentially dangerous chemical byproducts.
Enter PlasmaWave.
How is PlasmaWave different from old-fashioned ionizers?
The team at Winix developed a new approach to ionization, with chemical by-products in mindโthe result was PlasmaWave.
Winix designed a new type of low-voltage ionization process that help reduce air pollutants, while producing much lower levels of ozone.
PlasmaWave releases electrical discharges that alter the molecules in the air to create positive hydrogen and negative oxygen ions (a.k.a. hydroxyl radicals). These hydroxyl radicals attach themselves to air pollutants to break down their chemistry but they are considered safer than ozone as they have a much shorter life.
To be clear, when enabling PlasmaWave, the air purifier will still produce ozone as a byproductโbut it’s a very low concentration that is well below the 50 ppb limit established by CARB.
For example, the EnergyStar report for the Winix 5500-2 shows zero ozone production, as any ozone is likely removed by the activated carbon filter in the air purifier before the air leaves the machine.
Another air purifier that has been certified as ozone-free even though it uses ionization technology is the Blueair 211+ (check out the Intertek certificate)โBlueair has trademarked their ionization process under HEPASilent technology.
But real life is not reflected in lab tests and those who have a sensitivity to ozone might disagree with the 50 ppb limits. Plus, older and broken devices may, over time, release higher levels of ozone.
My tip is to look for models that will allow you to enable and disable the ionizer function, as is the case with Winix devices. I hear from consumers who only realized they are sensitive to the chemicals produced by ionization technologies after buying devices without an on/off button.
Thatโs why we donโt recommend devices that donโt allow you to disable the ionizer function, as we see with Blueair Blue Pure models.
How effective is Plasmawave?
Our data shows that this Winix technology leads to an improvement in particle removal performance.
We donโt test for VOC removal performance yet, so we donโt have any firsthand data on how effective PlasmaWave can be at dealing with unwanted smells and gases. We have read a 2022 study into the effectiveness of ionizer technology (not PlasmaWave specifically) that showed mixed reports, as researchers found a reduction of some VOC levels while recording an increase in others.
The good news is that we have collected firsthand data on the particle removal performance of PlasmaWave-enabled air purifiers.
We used our PurpleAir Zen sensor to record how long it took for each of the following Winix air purifiers to clear the air of all PM1 incense smoke particles inside our 728 cubic feet test room:

The CADR figures above are based on our own testing. We compared PM1 removal rates achieved by each device with and without PlasmaWave enabled against the natural ventilation rate of our 728 cubic feet test room using the Air Cleaner Efficacy Investigation tool (ACE IT).
As you can see from the table, our data shows that PlasmaWave generally helps remove small particles quicker when combined with the True HEPA particle filter used in the Winix devices, leading to a small increase in overall CADR of around 5% on average.
Modern mechanical-powered air filters are much better than in previous years, so high CADR can still be achieved without any bipolar ionization process.
If you have more questions about PlasmaWave or ionizers in general, please leave them in the comments below, and I will do my best to answer them.
The Blueair company is one of the best in manufacturing high-performance air purifiers. Based in Sweden, they have 19 models of purifiers in their arsenal, like the Blue Pure 211+. Each one is designed to suit various budgets and different room sizes.
Air purifiers are designed to run continuously, so their components will undergo a certain amount of wear and tear. Eventually, something will inevitably become a problem.
The unit doesnโt work as expected, or it wonโt switch on. It may be power related or, as is most common, clogged or dirty filters cause units to malfunction.
However, following a few simple steps can solve most issues easily and quickly. We have listed below the most common complaints, operational issues and possible solutions for each.
Problem 1: Your Blueair air purifier wonโt turn on
It can be annoying and frustrating when your air purifier just wonโt turn on, but there could be a simple explanation.
โ Is the unit plugged into the outlet?
Check that you have plugged the power cord into a wall outlet. It may have been dislodged or pulled out by accident. If the power cord is not connected to an outlet, plug it in.
โ Is the switch in the ON position?
Check the switch and make sure it is in the ON position. It is pretty easy to accidentally knock the switch OFF without realizing it.
โ Is the filter clogged?
Check to see if the filter is clogged. A clogged filter may cause problems and prevent the unit from turning on. To solve the problem, clean or replace it.
โ Could it be a tripped breaker?
Look at your breaker panel to see if any breakers have tripped. If one is not in the ON position, switch it to OFF and then back to ON.
โ Is the cover in place?
If you have previously removed the covers or grilles, check that theyโre seated properly on the unit. Many cleaners will not run as a safety device if the covers or grilles are not securely seated.
โ Is the power rating inaccurate?
If the power rating is incorrect, your purifier wonโt turn on. Check the outlet to make sure that the power rating is right.
Problem 2: Your Blueair air purifier wonโt draw airย
โ Are the filters dirty?
One cause of this problem could be the filters. If the filters are dirty, they will restrict the airflow, so make sure they are clean. If not, then either clean them or replace them.
โ Is there a blockage?
Make sure no obstructions are blocking the airflow into the unit. Something may have fallen in front of the intake grille, or something behind the grille inside the purifier is causing a blockage.
Remove the grille and check it is clean and free from obstructions.
Problem 3: No air blowing out your Blueair air purifierย
โ Are the filters clogged?
If the filter is clogged or severely dirty, then that will affect the airflow. Clean or replace the filters as needed.
โ Is the exhaust grille blocked?
A blockage to the exhaust grille could be another cause, as air cannot get out without a clear pathway. Remove the exhaust grille to see if there is an obstruction. Make sure it is clean and put it back in place.
Try running the purifier once you have done these two checks.
โ Is there a lack of clearance?
Reduced airflow can occur if the air intake and outlet are placed too close to objects. Simply change your purifierโs location to leave more space around it.
Problem 4: No noise coming from your Blueair air purifier
There could be a few reasons for no noise coming from the cleaner.
โ Is it switched on?
If not, then thatโs the problem. If it is plugged in and switched on, then it may be a problem with the filter.
โ Is the filter dirty?
Dirty or clogged filters will limit the unitโs airflow and cause it not to make a noise, so clean or replace them.
Problem 5: Weird noises coming from your Blueair air purifier
If you hear weird noises coming from the purifier, there may be a couple of reasons.
โ Are the filters clean?
Check the filters to ensure they are clean and replace them.
โ Are the intake or exhaust grilles blocked?
Remove both to see if anything is blocking them. Clean them as necessary.
โ Are filters installed incorrectly?
If the filters havenโt been installed correctly, they can produce a noise when the unit is running. Check them for correct installation and rectify them if needed.
Problem 6: Your Blueair air purifier isnโt cleaning air
If you feel the air in your home isnโt being purified, then it could be a couple of things.
โ Is there dirt or debris inside the unit?
Any dirt or debris entering the purifier will get trapped in the filters. As a result, it wonโt clean the air as efficiently as it should. If so, you must replace the filters as soon as possible.
โ Are the grilles blocked?
Grilles that have become blocked will prevent the air from flowing through the purifier resulting in the air not being cleaned. Make sure both the intake and exhaust grilles are free from obstructions.
โ Is the room coverage too large?
Be sure only to use your unit in the recommended room size.

Problem 7: There are no lights on your Blueair air purifier
If no lights are being displayed, the cause is usually to do with power or the lack of it.
โ Is the power off?
Is it plugged in and switched on? If the answer to both questions is yes, it may be the fuse.
โ Is there a blown fuse?
Look to see if the fuse has blown, and if necessary, replace it with an identical fuse and see if that solves the problem.
โ Is the cover in place properly?
Double-check that the cover is back in place if you have opened the purifier to change the filter. A wrongly fitted cover will stop the unit from running and no lights will be displayed.
Problem 8: The sensor isnโt functioning on your Blueair air purifier
โ Is the sensor blocked sensor?
If the sensor itself becomes blocked, it will not function correctly. Clean the sensor with a vacuum cleaner and see if that solves the problem.
โ Are the filters dirty?
If the filters are dirty, that can prevent or restrict the airflow, which can cause the sensor to malfunction. Ensure all the filters in the purifier are clean, or replace them if youโve had them for a while.
Problem 9: An orange/red light is showing on your Blueair air purifier
โ Does the filter need to be replaced?
If your Blueair model has a red or orange alert light, it is time to replace your air filter. This will usually happen after about six months of use.
Problem 10: A strange smell coming from your Blueair air purifier
โ Is the filter clogged?
If you experience a strange smell coming from your air purifier, the first thing to check is the filter. If you havenโt cleaned or replaced the filter in some time, it may be clogged with dirt or debris, causing the smell.
Dirt or other pollutants could block the exhaust or intake grilles. Remove them, clean them and see if that solves the problem.
How to contact Blueair customer service
If you experience any issues with your Blueair air purifier and the solution cannot be found in the user manual or this guide, you should contact Blueair customer service. You can email them or submit an online contact form.
Finding the manual for your Blueair purifier
If you have misplaced the operating manual for your Blueair purifier, you can visit the Blueair website to track it down or just click on the relevant link below.
Air purifiers are pretty simple devices, and they can have a huge impact on your air quality. But, as with any electrical item, they can go wrong sometimes. Luckily there is usually a quick fix. If you have a problem with your Blueair purifier, follow the steps in this guide to get it up and running again.
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 โCoreโ unit but is much smaller than any other air purifier in the series. I expected this unit would start a new trend for โmini 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.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
“Unfortunately, the Core Mini wonโt 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.”
With a CADR of 41 cfm, its air cleaning performance wonโt 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.
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.
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 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.
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.
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.
It is much smaller than most models, including the Levoit Core 300S, which will be considered a small air purifier by most people.
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 donโt believe many of the outrageous claims about the โscienceโ 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.
๐กexclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
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 wonโt tell you much, so check out how this compares to other popular small air purifiers on the market today:
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.
๐กexclusive 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 $7.11in 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.
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 itโs likely not the best air purifier for everyone.
Itโs 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.
๐กexclusive 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 itโs 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.
According to the World Health Organisation, in 2022, 99% of the worldโs population is breathing polluted air. Itโs not a new issue, either: air pollution and its health effects have been on humanityโs radar for thousands of years. But while the phrase โair pollutionโ might conjure up images of thick smog and eye-watering smoke, the most harmful type of air pollution particles are invisible to the naked eye.
Particulate matter 2.5 (PM2.5) describes pollutant particles so small that they can pass into your bloodstream and cause a range of health problems. In fact, theyโre responsible for the deaths of around 4.2 million people worldwide each year. As it wonโt disappear completely anytime soon, the WHO wants to reduce average annual levels to no more than five micrograms per cubic meter of air (ยตg/m3).
Much of the world still has a long way to go in reducing harmful air pollution levels, but the good news is that some cities are making great strides toward cleaning up the air. With this in mind, our researchers at HouseFresh wondered: based on changing local levels of PM2.5, where in the world has air pollution improved โ or worsened โ the most in recent years?
For each of the 480 global cities in our analysis, we calculated the average air pollution level of the first nine months of 2019 and 2022 (measured in PM2.5 micrograms per cubic meter of air, or ยตg/m3). We then worked out the value difference between 2019 and 2022 to discover the cities where air pollution levels had increased or decreased the most.
Key findings
Out of 480 global cities, Dammam in Saudi Arabia has seen air pollution levels increase the most (+111.1ยตg/m3).
Ulan Bator, Mongolia, has seen air pollution levels decrease the most (-23.4ยตg/m3).
In Europe, Salamanca, Spain, saw air pollution levels rise the most (+5.1ยตg/m3), while levels in Skopje, North Macedonia, have dropped the most (-12.4ยตg/m3).
In the U.S., Miami (FL) and Salt Lake City (UT) saw air pollution increase the most (+1.8ยตg/m3), and Omaha (NE) saw the biggest decrease (-1.2ยตg/m3).
Which capital cities have seen the biggest change in air pollution levels?
Generated primarily by burning oil and wood, PM2.5 โ also known as fine particles โ is the most unhealthy type of particulate matter (particles of pollution suspended in the air) to breathe in.
While the WHO has made clear that even very low levels of PM2.5 can cause harm to someoneโs health, its new guideline for average annual concentrations is five micrograms per cubic meter of air (ยตg/m3). In other words, any location with an average annual PM2.5 level higher than that is considered to have unhealthier air. For example, the average annual concentration of PM2.5 in Beijing, China, was 40.54ยตg/m3 in 2021 โ much higher than the WHO guideline.
To find out how air pollution is changing in 70 capital cities around the world, we calculated the difference between local levels of PM2.5 in the air in 2019 and 2022. Explore our map to view our results.
Of all capital cities, Baghdad, Iraq, has seen the most drastic rise (+31.6ยตg/m3) in PM2.5 levels since 2019. One 2015 study found that 81% of PM2.5 from the city is โdominated by dust, sulfate, gasoline and diesel.โ The biggest change for the better can be found in Ulan Bator, the capital of Mongolia, where PM2.5 levels have dropped by 23.4ยตg/m3.
Dammam, Saudi Arabia, has seen air pollution increase more than in any other city
Our data reveals the top 10 global cities where air pollution levels have increased the most since 2019. Claiming the unfortunate top spot is Dammam, Saudi Arabia, where local PM2.5 levels have risen by 111.1ยตg/m3 โ more than any other city on the planet. Dammam is a significant center for the Saudi oil industry and is home to both the largest port in the Persian Gulf and the largest airport in the world. One study labels airports as โhotspotsโ for harmful PM2.5 air pollution.
In Europe, air pollution levels have dropped the most in Skopje, North Macedonia
Our analysis of changing air pollution levels in European cities reveals that Salamanca, Spain, has seen PM2.5 levels increase the most (+5.1ยตg/m3) since 2019. Another Spanish city, Palma, comes second (+3.7ยตg/m3). According to IQAir, vehicles are the main source of pollution in the countryโs urban areas. On the plus side, both cities are required to introduce low-emission zones for vehicles from 2023 as part of Spainโs plan to reach climate neutrality by 2050.
Skopje, the capital of North Macedonia, was once the most polluted capital city in Europe due to emissions from local industry, outdated cars and residents burning wood and plastic to keep warm. The good news is that local levels of PM2.5 have dropped (-12.4ยตg/m3) more than in any other European city since 2019. In recent years, concerned locals have been campaigning for better air quality, and the cityโs Green City Action Plan has prioritized improving the air.
Air quality in Miami and Salt Lake City has worsened more than any other U.S. city
In the U.S., our analysis reveals that air pollution has increased the most in Miami, Florida, and Salt Lake City, Utah: in both cities, PM2.5 levels have risen by 1.8ยตg/m3 since 2019. Salt Lake City, in particular, is at a natural disadvantage when it comes to poor air quality: situated in a valley, the city is prone to a meteorological effect known as inversion, which is when the cooler air of the city is trapped underneath the warmer air above it, keeping pollution close to ground level.
The situation is brighter in Omaha, Nebraska, where air pollution levels have decreased by 1.2ยตg/m3 since 2019 โ more than any other city in the U.S. Raleigh in North Carolina has seen the next biggest drop in air pollution (-1.1ยตg/m3). In 2022, the Governor of North Carolina issued an executive order to increase the number of sales of zero-emission trucks and buses. According to the Environmental Defense Fund, transportation is one of the most polluting sectors in the state.
The cities where air pollution has increased and decreased the most since 2019
From one city to the next, air pollution levels can vary drastically. To find out how air pollution levels have changed since 2019 in a city of your choice, explore our interactive table below.
Itโs only natural to be concerned about high levels of air pollution where you live. Fortunately, there are steps you can take to look after your health. If youโre in the U.S., you can use AirNow to find out what your local areaโs Air Quality Index score is and follow their guidance depending on the result. This might mean limiting time outside on days with particularly high levels of air pollution.
On a wider scale, making small changes to your daily life can help lower the level of harmful particulate matter in the air. For example, you might want to consider using public transportation, and if you do need to use your car, make sure you donโt leave it idling. If you want to make a bigger change, the American Lung Association has more information on taking part in their Healthy Air Campaign.
METHODOLOGY
Using data from aqicn.orgโs World Air Quality Index for each city, we calculated the difference between the average PM2.5 micrograms per cubic meter of air (ยตg/m3) value for the first nine months of 2019 and the first nine months of 2022. A formula developed by AirNow was used to convert AQI PM2.5 into ยตg/m3 values.
The original data for New York City is split into its constituent boroughs, so we used the average value of pollution levels across all boroughs. Cities in Ukraine were excluded from the comparison due to the ongoing military conflict having an inevitable impact on the level of air pollution. The data was collected in October 2022.
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 donโt just sell fan and air purifier combos but also garden hoses and frying pans.
As a manufacturer who sells direct, they donโt 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.
How we test air purifiers
Read our full testing methodology.
The lowdown on the ULTTY Bladeless Fan and Air Purifier Combo CR021
“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.”
Canโt 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, itโs 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.
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 wouldnโt 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 wonโt 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.
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.
The big downside about the type of filter ULTTY uses is that it has no activated charcoal – it doesnโt 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. Thatโs why we see activated charcoal used in budget air purifiers like the Levoit Core 300.
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.
We did this by performing the same test that all our air purifiers are put through to see how fast they clean one incense stickโs 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 wasnโt 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. Itโs 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, itโs 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.
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 donโt have to worry about them poking it with their fingers.
If you like the idea of a fan and air purifier that doesnโt cost the earth, then you donโt 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.
