Our verdict

The IQAir Healthpro plus is the best pure HEPA + activated charcoal air purifier on the market. It’s perfect for a large room or open space area but doesn’t come cheap with both the initial unit cost of nearly $900 plus the electricity and filter costs adding an extra $365 per year.


If you don’t mind the use of ionizer technology, then you will likely prefer to look at other units that can perform at similar levels for less cost (such as the Blueair Blue Pure 211+), but if you have any concerns about ionizer technology and want the best performance money can buy, then this is the air purifier you will want in your home.

IQAir has been in the business of cleaning air since 1963 and currently, all manufacturing is based in Switzerland and southern Germany. It’s still owned by the original Hammes family and is now a major player in the US and China market for air purifiers. You can even watch Frank Hammes step into a smoke chamber with only this air purifier to protect him!

This particular model that I am reviewing is the IQAir Healthpro Plus 250, which is priced at $899 and so is at the higher budget end for most home users. 

This particular unit has been on the market since 2017 and has won several awards, including the top air purifier from the Evening Standard in the UK.

While there is a ton of positive sentiment behind this particular air purifier, I will not let that affect my overall review as I want to uncover if it is worth its large price tag.

As with all the air purifiers we review here at HouseFresh, we bought the IQAir Healthpro Plus with our own money, and we have tested it both in our testing room and in our home to evaluate its performance in real-life situations.

  1. In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
  2. We set up our trusted Purpleair Indoor Sensor with the latest Bosch gas sensor to track levels of PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 and VOCs in the air.
  3. We switch the air purifier to its highest speed and measure how long it takes to get our room air quality down to PM1 level to 0.
  4. 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.
  5. We track sound levels emitted by the air purifier at different fan speeds with the help of a commercial sound meter.

The reason we do all this is to be able to compare different products side by side. It wouldn’t be fair otherwise to do so using only the specifications provided by manufacturers, as we know for a fact that some manufacturers inflate (or even hide) important metrics related to performance.

The lowdown on the IQAir Healthpro Plus

“The IQAir Healthpro plus is one of the best pure HEPA + Activated charcoal air purifiers on the market, BUT its outstanding performance doesn’t come cheap.”
— Danny Ashton, HouseFresh Founder & Senior Writer

If you don’t have time to read my full review, you can just go through my pros and cons for a quick snapshot of my findings:

What we really like

It is manufactured in Switzerland utilizing the best technologies and the safes procedures — the performance of each unit is manually tested before it’s delivered to your home
Top performance with 300 CFM and the ability to remove odors with 5 lbs of activated charcoal — it cleaned our test room in 25 minutes.
It doesn’t use an ionizer nor generates harmful byproducts such as ozone gas. I’m still not sold on the benefits of ionizers long term, unlike HEPA technology, which has been proven again and again to be a great way to keep the air clean.
HyperHEPA is best in class for any air purifier — it can clean 99.5% of particles smaller than 0.003 microns
It comes with a 10 year warranty
The filters can last up to 4 years, when most units have filters that need to be replaced every 6-12 months.

What we think could be better

It comes without an auto function and app support
I found the wheels were challenging to fit, and a quick search on Google showed me that i wasn’t the only one
The price is at the top end of the market for a unit that can offer 300 CFM performance

The specifications

Before we jump into the stats it’s worth taking the time to talk a little about CADR and CFM. The team at IQAir are not big fans of CADR as they believe it is biased in favor of Hybrid units (those that use Ionizer and HEPA) You can read more about their argument over at the IQAir blog.

In simple terms, IQAir doesn’t use any ionizer technology compared to others in this space (Blueair and Alen) due to health concerns and efficiency decreases from particle charging.

Whilst a hybrid technology could clean the air quicker, if you had similar concerns about ozone or ionizers, then you would want to take a closer look at something like the IQAir HealthPro Plus.

It looks like an 80s printer

“Is it a printer?”

That was the first thing my wife said when she saw it, and I have to agree, as the Healthpro Plus gives off office printer/copier vibes.

Once I saw the IQAir Healthpro Plus box, I knew there was a huge unit inside. It was a little intimidating, actually.

The IQAir Healthpro Plus comes well packaged in a large box and includes a remote, wheels, and power cable are packed separately.

Inside the box, you can also find a certificate of performance. IQAir’s team in Switzerland makes sure that every unit is tested before it goes out to you. As you can see from the certificate, my unit actually performed better than the published rate, with Speed 6 providing 494 m3/h vs 440 m3/h.

As I mentioned above, inside the box, you will also find the wheels, which you will need to attach to your Healthpro Plus yourself. You just need to connect the wheels to the brackets at the bottom of the unit, so it should be a straightforward job for you…

Unfortunately, it wasn’t a straightforward job for me. Unlike most castor wheels, these didn’t just click into place with the brackets. The only way I could manage to make the wheels click into place was by putting my entire body weight onto the unit. Throughout this process, I was very worried about the possibility of breaking the whole thing.

This was the only complication I ran into when it came to using the IQAir Healthpro Plus. I will be okay if I don’t need to remove the wheels for whatever reason, as I worry they are now latched on super tightly and might break apart if I force them out. This is something that IQAir could definitely improve in future versions.

Once the wheels were on, I could move the IQAir Healthpro Plus around the house to test its portability and closely inspect the unit.

The main case is a thick plastic shell that houses each of the different filters with a fan at the bottom that draws air up through the pre-filter and into the other filters. 

Once I finished testing the air cleaning speed, electricity consumption and noise levels generated by the IQAir Healthpro Plus, I had to find a spot for it in my home as I was assigned to use this air purifier long-term to assess potential issues that could arise. Right now, I have the Healthpro Plus in my hallway, and while it did get a strange look from my wife the first morning I set it up, it’s now a part of the house and doesn’t get in the way. The positioning is great because it sits in the middle of the house and it catches any cooking smells from the kitchen or the smoke from the wood burner in the TV room before they travel to the rest of the house.

Simple controls without smart functions

The buttons on the control panel at the top of the IQAir Healthpro Plus are easy to use, without unnecessary options or cryptic icons.

This fairly simple system offers users the ability to increase fan speed with the touch of a button, and also check out the amount of time left in the filters before they need to be replaced. It’s a straightforward system compared to many other more modern air purifiers with multiple screens and touch buttons.

The IQAir Healthpro Plus comes with a remote control that is basically a portable version of the control panel embedded at the top of the unit. I quickly stored it because I have small children, who like to play with (and misplace) remote controls. I prefer to use the buttons on the control panel anyway.

IQAir Healthpro Plus Remote

I was a little disappointed not to see the implementation of a smart mode that would allow the IQAir Healthpro Plus to come on automatically when it senses pollutants in the air, but this is a technology that requires an onboard air quality sensor and that is not available with this unit at this moment in time.

That being said, the controls include a timer button to program a routine for the air purifier to switch itself off at night or when you leave the house, for example. However, you have to set this manually each day, setting hours for the air purifier to turn itself on and off. Not ideal by any stretch.

Another thing that would be nice to have is a child lock. My youngest loves buttons, so it is not uncommon to find him turning the IQAir Healthpro Plus on and off.

Outstanding filter technology

The IQAir Healthpro Plus is heavy at 46Ibs and I was worried how much of that weight was wasted as part of the chassis. I was wrong.

This is not a large air purifier full of empty space. When I opened the top cover of the Healthpro Plus, I could see that the engineers at IQAir had used every inch to fill it with filters. This means that will be getting a good amount of performance for the floor space it takes up.

The IQAir Healthpro Plus comes with a V5-Cell filter, which is packed with over 5 lbs of activated carbon and KMn05 alumina to deal with odors and VOCs.

Upon closer inspection, one can see the individual pellets of activated carbon inside the V5-Cell Filter:

How IQAir’s HyperHEPA filter works

The initial pre-filter stops large particles like pet dander and dust particles. These are pulled into the fan as air passes through the V5-Cell, removing gas and odors before the air is finally pushed through the primary HyperHEPA filter.

The benefit of this layout is that only pre-cleaned air passes through the most expensive HyperHEPA filter and can be found for around $200 (the pre-filter is half that price.)

According to IQAir, you will need to replace the pre-filter every 18 months, but you only have to replace the HyperHEPA every 4 years, which compares favorably to other high-end air purifiers.

The IQAir Healthpro Plus cleared our test room in 25 minutes

As I mentioned at the beginning of this review, we always test every air purifier performing the same job (cleaning the air from pollutants emitted by a powerful incense stick) under the same conditions in the same test room. This allows us to compare different air purifiers like for like.  

I used an air quality monitor to track air quality changes over time to find out how quickly the IQAir Healthpro Plus can reduce the amount of PM1, PM2.5, and PM10 particles in the air. These tiny particles are responsible for the bulk of health issues relating to indoor air pollutants, as they can make their way deep into the lungs.

The IQAir HealthPro Plus took 25 minutes to get the room back to a reading of 0.01 PM1, 0.16 PM2.5, and 0.16 PM10.

You can see the full data here:

You can see the sheer power of the IQAir Healthpro Plus by looking at how quickly the air sensor changes when put close to the airflow exit on this air purifier in the video below:

From an air cleaning performance perspective, the IQAir Healthpro Plus performed as well as I expected. I can now understand why Frank Hammes was so confident about using this air purifier as his primary air supply in this video where he is locked in a smoke chamber.

Air cleaning performance test Results

The table below allows you to compare the performance of the IQAir Healthpro Plus against the top 10 units we have tested:

The IQAir Healthpro Plus is one of the best pure HEPA + activated charcoal air purifiers on the market, but it is also quite pricey.

Noise levels test results

Here is how the IQAir Healthpro Plus compares against units with a similar air-cleaning performance in regards to noise output:

If you are interested in hearing the noise to find out just how loud the IQAir Health Pro Plus is, then be sure to check out the video below which shows noise levels generated by the unit as you move from the lowest to the highest speed levels:

The cost to run a Healthpro Plus: $365.04 per year

A big unit like this does cost a lot more in the initial outlay, but another thing to consider is the extra costs for electricity and filters. 

1. Electricity costs = $165.04 per year

Rather than take the averages from the manufacturer’s website, I tested the electricity usage for each different speed for this air purifier:

  • Speed 1: 21 watts
  • Speed 2: 38.7 watts
  • Speed 3: 57.7 watts
  • Speed 4: 81.6 watts
  • Speed 5: 113.9 watts
  • Speed 6: 156.5 watts

Using the Department of Energy’s appliance energy calculator, we can see that at its highest setting, this air purifier will cost $165.04 per year.

2. Filter costs = $200 per year

Another area to consider is the replacement of filters. The genuine IQAir HyperHEPA and V5 filters are currently out of stock on Amazon but the pre-filter is available at $155.78 – remember the pre-filter needs to be changed every 18 months.

There are a number of generic filters that fit the IQAir Healthpro units with packages of all three including V5 and HyperHEPA coming in at $249.99. That being said, these filters are not built by IQAir so performance may not be at the same level.

Whilst you would hopefully not have to change all the filters every year, you would expect to budget at least $200 per year for filter running costs on top of the unit’s costs.

Bottom line

I had high expectations for the IQAir Healthpro Plus, and its performance in our real-world tests didn’t disappoint. 

Yes, it isn’t cheap but any level of performance of 300 CFM doesn’t come cheap with comparable high-performance units such as the Blueair classic 405 at $599 and the Alen 75i at $749. These units can perform at this level for less money due to their hybrid use of an ionizer combined with a HEPA filter. 

IQAir is clear that they don’t recommend Ionizer technology but I could totally understand situations such as large amounts of smoke that you would benefit from this extra power without the extra cost of a pure HEPA /activated charcoal system. 

The question of whether you should get a unit like the IQAir Healthpro Plus will depend on your position on using hybrid systems that utilize ionizers. If you have any concerns about ionizers or specific health concerns, then the Healthpro Plus is currently the most powerful HEPA/Activated charcoal unit on the market. If you don’t want to get the odor and VOC filter, you can buy a version that has a more powerful HyperHEPA performance at $50 less, which is the IQAir HealthPro (no plus) and IQAir Healthpro compact — it might make more sense depending on your specific use case.


We calculated the monthly energy consumption costs with the help of the Department of Energy’s appliance energy calculator. We calculated yearly costs associated with running the IQAir Healthpro Plus for 24 hours a day for 365 days. We ran this calculation utilizing the US average utility rate of $0.12/kWh as of February 4th, 2023.
