Our verdict

The IQAir HealthPro Plus is the best pure HEPA + activated charcoal air purifier available to buy right now. 

 

It’s perfect for a large room or open space area, but it doesn’t come cheap: the HealthPro Plus comes with an upfront cost of nearly $900, plus additional $365 per year in electricity and filter replacement costs.

 

If you don’t mind the use of ionizer technology, you might want to look at other air purifiers with similar performance, such as the Blueair Pure 211+. 

 

But if you have any concerns about ionizer technology or have a severe health issue and want the best air cleaning performance money can buy, then the IQAir HealthPro Plus is the air purifier you will want in your home.

IQAir was founded in 1963 by Klaus and lifelong asthmatic Manfred Hammes to reduce indoor air pollution from coal smoke from ovens that people used in their homes at the time. All IQAir air purifiers are manufactured in Switzerland and southern Germany, which makes IQAir stand out against its competitors, who mainly produce devices in China.

The Hammes family still owns the company and is now a significant player in the air purifier markets across the U.S. and China. You can even watch Frank Hammes step into a smoke chamber with only the IQAir HealthPro Plus to protect him!

This particular model that I am reviewing is the IQAir HealthPro Plus 250, which is priced at $899 and is at the higher end of the budget for most home users. That is why I will try to uncover whether the HealthPro Plus is worth its significant price tag — I don’t want anybody to buy this expensive air purifier and then regret it.

Why you can trust this review

As with all the air purifiers we review here at HouseFresh, we bought the IQAir HealthPro Plus with our money to test its performance, noise levels generated and electricity consumption. We don’t run ads on our site or accept freebies, so all our reviews are impartial, and we have no issues saying when a product sucks or doesn’t provide value. We do all this to compare different air purifiers side by side; you can read more about how we test air purifiers.

It wouldn’t be fair to use only the specifications provided by manufacturers, as we know that some manufacturers inflate (or even hide) important metrics related to air cleaning performance. That is why we not only conduct all these tests, but we also record them on video, so you can see exactly how the air purifier performed:

In addition to running all these experiments in our test room, I have been using the unit in my home for over a year, so I can share my impressions of having an IQAir HealthPro Plus in real-life situations.

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. It costs much more electricity and filter costs, which might be overkill for many household use cases.”
— 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 procedures, and the performance of each unit is manually tested before it’s delivered to your home.
It offers top performance with 300 CFM and can remove odors, gases and VOCs thanks to its 5 lbs of activated charcoal — it cleaned our test room of PM1 in 24 minutes.
It doesn’t use an ionizer nor generates harmful byproducts such as ozone gas. I’m still not sold on the long-term benefits of ionizers, 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, which is perfect for those with health conditions that means they need to reduce the level of exposure of particles to close to zero.
It comes with a 10-year warranty and the filters can last up to 4 years, when most units come with a 1-year warranty and filters that need to be replaced every 6-12 months.

What we think could be better

No app or auto-mode. But it does have a remote, so you can still adjust settings without using the onboard buttons.
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 offering 300 CFM performance.

IQAir’s stance on CADR tests

Before we jump into the stats, it’s worth taking the time to talk a little about CADR and CFM. The team at IQAir is not a fan 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 on IQAir’s 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. While hybrid technology could clean the air quicker, if you have similar concerns about ozone or ionizers, you should look closely at something like the IQAir HealthPro Plus.

Okay, maybe it does look like an 80s printer

“Is it a printer?” That was the first thing my wife said when she saw it.

The IQAir HealthPro Plus gives off office printer/copier vibes, but that might not be a bad thing if you are into vintage electronics.

Once I saw the IQAir HealthPro Plus box, I knew a huge unit was inside, and you would need two people to help move the box. The IQAir HealthPro Plus comes well packaged in a large box and includes a remote, wheels, and power cable packed separately.

Inside the box, you can also find a certificate of performance. 

IQAir’s team in Switzerland ensures that every unit is tested before it goes out to you. As you can see from the certificate, my unit 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 must 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, right?

Unfortunately, it wasn’t a straightforward job for me. 

Unlike most castor wheels, these didn’t just click into place with the brackets. I could only make the wheels click into place 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 encountered when using the IQAir HealthPro Plus. I hope 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 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 housing each filter with a fan at the bottom that draws air 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 reasonably 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 more modern air purifiers with multiple screens and touch buttons.

IQAir Healthpro Plus Remote

I was a little disappointed the IQAir HealthPro Plus doesn’t include a smart mode that would allow it 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 isn’t available on this model.

IQAir has launched a smart air purifier model that includes an in-built air quality sensor and app support: the Atem X. It doesn’t come cheap at $1,399, but we are excited to test and review it before the end of this year. 

That being said, the controls on the IQAir HealthPro Plus do 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 daily, setting hours for the air purifier to turn 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.

On the plus side, the IQAir HealthPro Plus comes with a remote control that is a portable version of the control panel embedded at the top of the unit.  

It’s a super simple remote, with buttons for all six fan speeds and to set the timer. 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.

Outstanding filter technology

A beast of an activated carbon filter with over 5lbs of carbon and zeolite mix.

IQAir’s HyperHEPA filter is a beast.

The IQAir HealthPro Plus is heavy at 46Ibs, and I was worried about 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 we will be getting a good amount of performance for the floor space it takes up.

The initial pre-filter stops large particles like pet dander and dust particles:

The air continues to be pulled into the fan, and as it passes through the V5-Cell, this next layer of filtration removes gas and odors:

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

The V5-Cell filter is packed with over 5 lbs of activated carbon and KMn05 alumina, making it one of the most powerful air filters on the market to deal with odors and VOCs.

You can see here how it compares with the activated carbon filter on the Levoit EverestAir:

Once the air passes through the V5-Cell filter, it reaches the last layer of filtration, where the air is finally pushed through the primary HyperHEPA filter.

Using a high-grade filter like HyperHEPA adds to the device’s cost and means more energy is required to push enough air. But this is an excellent feature for those who want to ensure that only clean air is released from the device, such as those with serious health issues or in a hospital setting.

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

According to IQAir, you must replace the pre-filter every 18 months. Still, you only have to replace the HyperHEPA every four years, which compares favorably to other high-end air purifiers.

You can see in the video below how the process for replacing the filters goes:

As the case with Levoit showed us, many manufacturers will say that a filter is HEPA grade but often do prove it with third-party lab reports. We have no worries about the IQAir HealthPro Plus as Interbasic Resources, Inc. did third-party testing on it and made the report available to the public.

They compared the effectiveness of the HyperHEPA filters with other air cleaning technologies (synthetic HEPA, fan-powered electronic air cleaners and electronic air cleaners without a fan) across a range of different particles, from viruses to pollen. IQAir’s HyperHEPA was able to sustain 99-100% removal efficiency.

That said, this is not a requirement for most consumers just looking to reduce the number of particles in the air, as standard synthetic filtered devices can eventually clean the air in the room with multiple passes through the filter.

The IQAir HealthPro Plus cleared our test room in 24 minutes

Considering the amount of carbon this air purifier uses, its particle removal is impressive.

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 of 728 cubic feet and tracking PM1, PM2.5 and PM10 using two PurpleAir air quality sensors.

We do this because it allows us to compare different air purifiers like-for-like and calculate estimates of CADR even when manufacturers don’t provide it, which is the case with IQAir. 

The IQAir HealthPro Plus took 24 minutes to return the room to a reading of 0 PM1 when tracked using the PurpleAir indoor sensor and 28 minutes to achieve 0 PM1 with the newer Purple Zen sensor.

As of 2024, we now film all our performance tests so you can view the test below:

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, especially when we consider the high-grade HEPA and large amounts of activated carbon used. I can now understand why IQAir CEO 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 compared

The table below allows you to compare the performance of the IQAir HealthPro Plus against similarly priced or sized units, including the fastest air purifiers we have tested:

The HeathPro Plus matched the Alen BreatheSmart 75i, but it was 13 minutes faster than the Austin Air HealthMate at removing the smoke from the air in our test room.

Airflow test results

We also used our Testo 410i anemometer to measure directly from the air outlet how fast the airflow is at each fan speed when taken directly from the device.

We found that at speed one, airflow averaged 0.5 m/s, and at speed six, it achieved 3.65 m/s. 

It is worth mentioning that I measured the airflow one year after setting up the HealthPro Plus in my hallway to ensure it would perform at its best as the filters have been ‘broken into’.

Noise levels test results

These are the results for each fan speed from 3ft away:

SpeedSound Level
136.9 dB
237.2 dB
340.9 dB
447.2 dB
553.9 dB
661.2 dB

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

AIR PURIFIER MODELSOUND LEVEL AT TOP SPEED (dB) TIME TO CLEAN OUR TEST ROOM
Coway Airmega AP-1512hh Mighty60.1 dB25 minutes
Austin Air HealthMate HM40061.5 dB37 minutes
Okaysou AirMax10L Pro55.6 dB44 minutes
Levoit Vital 200S57.7 dB18 minutes
IQAir Healthpro Plus61.2 dB26 minutes

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 an IQAir HealthPro Plus: $421.47 per year

The powerful fan and high-quality filters don’t come cheap.

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 = $221.47 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.

SpeedEnergy recorded
116.5 watts
232.7 watts
347.3 watts
469 watts
594.3 watts
6145.2 watts

This air purifier will cost $221.47 per year at its highest fan speed, based on my calculations using the latest average electricity price per kWh reported by the U.S. Bureau of Labor Statistics and assuming you would run the HealthPro Plus 24/7.

Compared to other devices, the IQAir Healthpro is more power-hungry than many of the devices we have tested:

AIR PURIFIER MODELENERGY CONSUMPTION AT TOP SPEED (watts)TIME TO CLEAN OUR TEST ROOM
Coway Airmega AP-1512hh Mighty77.3 watts25 minutes
Austin Air HealthMate HM400147.6 watts37 minutes
Okaysou AirMax10L Pro58.05 watts44 minutes
Levoit Vital 200S44.55 watts18 minutes
IQAir Health Pro Plus145.5 watts26 minutes

2. Filter costs = $200 per year

Another area to consider is the costs associated with replacing the filters. 

The original IQAir pre-filter is available for $155.78. Remember, it needs to be changed every 18 months.

The genuine IQAir HyperHEPA costs $199.00, but it only needs to be replaced every four years.

IQAir’s V5-Cell Gas and Odor Control Filter lasts up to two years, and it costs $99 when writing this review.

The good news is that generic filters that fit the IQAir HealthPro Plus, with packages of all three, including V5 and HyperHEPA, come in at $249.95.

That said, IQAir does not build these filters, so their performance may differ, and they will likely not put these through the same lab tests to certify the HEPA grade.

While 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, which is at the highest level compared to other air purifiers we have reviewed.

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 605 at $799.99 and the Alen BreatheSmart 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 understand situations where you would benefit from this extra power without the extra cost of a pure HEPA and activated charcoal system, such as cases when you are dealing with large amounts of smoke.

Whether you should get a unit like the IQAir HealthPro Plus depends on your position on using hybrid systems that utilize ionizers and your health issues. If you have any concerns about ionizers or specific health concerns, then the HealthPro Plus is currently the most powerful HEPA + Activated Charcoal air purifier on the market.

Suppose you don’t want to get the odor and VOC filter. In that case, 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 — both of them might make more sense, depending on your specific use case.

SOURCES

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