0.003 microns. Among everything that is special about the Swiss-made IQAir HealthPro Plus air purifier, this number is at the top. It’s the reason why IQAir HealthPro Plus is often called the ‘#1 Rated Air Purifier For Allergies And Asthma‘.
The width of a single human hair is about 75 microns. As we’ll see in this IQAir HealthPro Plus review, everything revolves around the most thorough removal of air pollutants from indoor air.
The reason for that is the number 0.003 microns; it’s the average sizes of pores in the HyperHEPA air filters IQAir air purifiers use famous for.
Understanding The IQAir’s HyperHEPA Filters
In essence, IQAir HealthPro Plus is so special because it uses HyperHEPA filters that are 100x better than True HEPA filters and 30x better than medical-grade H13 HEPA filters. Here is a quick comparison in terms of the size of air pollutants these 3 filters can capture:
- True HEPA filters can capture more than 99.97% of 0.3-micron air pollutants. That’s 1/250 of the width of human hair.
- H13 medical-grade HEPA filters can capture more than 99% of 0.1-micron air pollutants. That’s 1/750 of the width of human hair.
- IQAir HealthPro Plus’s HyperHEPA filters can capture more than 99.5% of 0.003-micron air pollutants. That’s 1/25.000 of the width of human hair.
Only Hyper HEPA – filters used by IQAir HealthPro Plus – can capture the smallest ultrafine air pollutants. In fact, according to IQAir:
“Ultrafine particles are smaller than 0.1 microns, make up about 90% of all airborne particles, and have been linked to heart attacks, strokes, asthma, and even cancer.”
Here’s a visual representation of True HEPA vs. H13 HEPA vs. IQAir HealthPro Plus’s HyperHEPA filters:
It’s pretty obvious that IQAir HealthPro Plus is one of the most advanced and thorough air purifiers.
Here’s the deal:
Despite being the class-of-its-own air purifier, we are going to review the IQAir HealthPro Plus like any other air purifier. We’ll look at under the hood at its heart – the filtration system – as well as the air purifier’s CADR rating, coverage area, noise levels, prices, and any available IQAir HealthPro Plus sales.
There’s one thing we need to keep in mind when going through all the customary air purifier metrics: No other air purifier can capture the ultrasmall air pollutants like IQAir air purifier. It’s truly an incredible better-than-medical-grade air purifier.
Here’s the full list of the IQAir HealthPro Plus’s specification and features we’re going to look into:
IQAir HealthPro Plus Review At-A-Glance: Hands down the most thorough class-of-its-own air purifier for large up to 1125 sq ft spaces. IQAir HealthPro Plus can capture 100x smaller particles than a True HEPA filter, and it about 30x more thorough than medical-grade H13 HEPA filters. Drawbacks: This unique Swiss-made air purifier has a higher price, obviously. Overall, it’s one of the best air purifiers, clearly worth the cost. Its the title of ‘#1 Rated Air Purifier For Allergies And Asthma’ is very well deserved.

IQAir Air Purifier Filters
The filtration system is the heart of any air purifier. In the case of IQAir HealthPro Plus, the filters are especially important. They are the ones that enable this Swiss-made machine to capture even the smallest ultrafine air pollutants.
As you can see from the HEPA filter comparison visualization above, HyperHEPA filters IQAir uses can, in addition to coarse and fine particles, take care of ultrafine particles.
These include tobacco smoke, certain viruses, soot, and pet dander. According to IQAir, these ultrafine air pollutants only IQAir HealthPro Plus can capture may affect the following organs:
- Eyes.
- Nose.
- Throat.
- Lungs.
- Heart.
- Brain.
- Kidney.
- Liver.
It seems that by removing them you’re removing the potential threat. Here is the total system efficiency difference the use of HyperHEPA filters makes, compared to filters employed by other air purifiers:
It gets even better:
HEPA filters need to be replaced, on average, every 6-9 months. In comparison, the IQAir’s HyperHEPA filters need to be replaced, on average every 4 years and 2 months. That’s 50 months in total.
50-month HyperHEPA filters can almost be considered permanent filters.
The very capability of HyperHEPA filters is unmatched by any other air purifier, including the best Alen BreatheSmart, BlueAir, Coway, or even Dyson air purifiers.
This is why both IQAir HealthPro and IQ Atem are on the list of the best air purifiers in 2023.
HyperHEPA is the main filter. IQAir also uses brilliant and long-lasting secondary filters:
Secondary Filtration (PreMax And V5-Cell Filters)
PreMax is a glass microfiber pre-filter. Its main job is protecting the precious HyperHEPA filter by removing larger particles. These larger particles also need to be removed in order to improve indoor air quality. If they would have to be filtered out by HyperHEPA filter, it would quickly reach the filter’s capacity; its lifespan would be shortened.
Pre-filter is classified as EN 779 class F8. That means that it removes more than 55% of any air pollutants that are larger than 0.3 microns.
PreMax’s total surface area is more than 20 square feet to ensure a high capacity and long lifespan. If you run the IQAir HealthPro Plus 10 hours per day on speed 3, they are tested to last for 16 months, after which time you will need a replacement filter. Replacement PreMax filter cost about $80, you can get them here.
The 2nd secondary filter is the odor-removing V5-Cell filter. This is an advanced granular activated carbon filter, design to remove gaseous indoor air pollutants. These include different odors and chemicals; from kitchen odors to cigarette smells, volatile organic chemicals (VOCs), and even formaldehyde.
The V5-Cell is not a standard activated carbon filter. It is an advanced filter that uses both adsorptions as well as chemisorption to remove odors, and have a prolonged lifespan of about 2 years.
While standard carbon filters weigh from 0.5 lbs to 2 lbs, the V5-Cell weighs 5 lbs. With activated carbon, the weight is the most important aspect (you can read more about that in the Essential Air Purifier’s Guide here). Replacement V5-Cell filter costs about $100 and it’s available here.
IQAir HealthPro Plus CADR Rating
The CADR rating is the one metric, based on which we can compare all portable HEPA air purifiers. This Clean Air Deliver Rate rating was developed by AHAM and measured the efficacy of air purifier to reduce 3 most common air pollutants:
- Smoke particles between 0.09 and 1.0 microns in diameter.
- Dust particles between 0.5 and 3 microns in diameter.
- Pollen particles between 5 and 11 microns in diameter.
IQAir HealthPro Plus has a high 300 CADR rating, thanks to the efficacy of HyperHEPA filters.
What is really important to understand that IQAir HealthPro Plus goes far beyond what its CADR rating might suggest. As we see, the CADR rating is measured for particles that at bigger than 0.09 microns; that’s something HEPA filter air purifiers are good at.
IQAir HealthPro Plus can remove particles that are a lot smaller than what the CADR rating measures. For example, the HyperHEPA filter additionally removes all allergens with sizes between 0.003 and 0.09 microns that CADR rating is unable to measure.
With such extremely high efficiency for small as well as ultrasmall air pollutants, the IQAir HealthPro Plus has a big coverage area:
IQAir HealthPro Plus Square Footage (Room Size)
IQAir HealthPro Plus is one of the biggest portable air purifiers. It has a recommended coverage area of up to 1,125 sq ft and can thus be considered a whole-house air purifier.
It has 6 fan speed settings in total. The higher Speed 6 can achieve the max. airflow of 300 CFM. This is the very setting to set for 1,125 square footage.
You can also use speed settings from 1 to 5. Here is the calculated square footage or room size of all fan speed settings:
- Speed 1: Airflow of 40 CFM with 150 sq ft coverage.
- Speed 2: Airflow of 75 CFM with 281 sq ft coverage.
- Speed 3: Airflow of 130 CFM with 488 sq ft coverage.
- Speed 4: Airflow of 170 CFM with 638 sq ft coverage.
- Speed 5: Airflow of 200 CFM with 750 sq ft coverage.
- Speed 6: Airflow of 300 CFM with 1,125 sq ft coverage.
It’s useful to keep these coverages in mind. IQAir HealthPro Plus is Swiss-made and they use the metric units (namely cubic meters instead of CFM) while in the US we use imperial units.
Let’s look at how much electricity is needed to power IQAir HealthPro Plus air cleaner:
IQAir HealthPro Plus Power Consumption (Wattage)
IQAir HealthPro Plus required 220/240V voltage at 50/60 Hz to run.
As with all air purifiers, IQAir HealthPro Plus doesn’t spend a whole lot of electricity. However, because it’s a bigger device and the fact that it needs higher air pressure to push the air through smaller HyperHEPA wholes, it has an above-average wattage.
Obviously, every speed setting has its own wattage requirements. Speed 1, for example, is powered by 20 Watts. The highest Speed 6 is powered by 135 Watts. The standby wattage is below 1W.
What does that mean in electricity costs?
Not much. If you run the IQAir HealthPro Plus on the highest speed 24/7, it will spend 3.24 kWh per hour. With less usage and at a middle-level speed setting, it’s more realistic that you will spend about 1 kWh per day on powering the IQAir air purifier.
That equals to about $1/week in electricity costs or about $50/year.
Power consumption is quite insignificant. What really matters, and what many people who are buying an IQAir air purifier are afraid of, are high noise levels:
IQAir HealthPro Plus Noise Levels
Bigger air purifiers like IQAir HealthPro Plus tend to have higher noise levels. That’s only understandable.
IQAir HealthPro Plus has an additional problem to overcome: It has to force air through a 100x smaller sieve than in the case of True HEPA filtration. That amounting pressure before the HyperHEPA filter should, in theory, increase noise levels.
Fortunately, IQAir HealthPro Plus noise levels are relatively low for its size and its remarkable filtration efficiency. At the highest Speed 6, the maximum noise levels IQAir HealthPro Plus generates is 57 dB. That’s more than bedroom-friendly Alen BreatheSmart air purifiers but a lot less than Molekule air purifiers, for example.
At the lowest Speed 1, the IQAir HealthPro Plus has a noise level of only 22 dB. The noise levels increase to 33 dB, 41 dB, 47 dB, 52 dB for Speeds 2, 3, 4, and 4, respectively.
All in all, achieving low noise levels is a bigger air purifier requires quite a lot of brilliant engineering. It’s clear that IQAir HealthPro Plus was splendidly designed in this aspect as well.
IQAir Air Purifier Special Features
IQAir HealthPro Plus has a barrage of special features. The most important ones ensure quiet and high-efficiency, as we have seen in the review of IQAir HealthPro Plus’s specification thus far.
These include:
- Triple-Seal technology. Designed to eliminate air leakages via the use of 3D UltraSeal, 100% sealing filter media, and individual seals. Essentially, no air escapes unfiltered.
- New upgraded fan. This is one that can deliver 300 CFM airflow, allowing IQAir air purifier to be used in up to 1,125 sq ft area.
- EvenFlow diffuser. Patented tech by IQAir, this diffuser can achieve 320° air delivery without using noisy outlets or annoying drafts.
All these extra features are there to achieve smooth high-caliber operation. The extra features that will help users control and maintain the IQAir air purifier include:
- Operation options that can be programmable, and set via remote control.
- Monitoring of filter-life (light will go off when any filter needs replacing).
All in all, most of these technological advancements are there to achieve such super specs.

Final Verdict On IQAir Air Purifier
If you’ve read through all the specification assessments, you can see that the IQAir air purifier is a remarkable machine. The only competition it has is the Alen BreatheSmart 75i.
A lot of it can be put down to the highest efficiency for the smallest air pollutants, thanks to the thorough HyperHEPA filters. But that’s only a part of it.
Secondary PreMax and V5-Cell filters, low noise levels, energy-efficiency, and affordable price are all part of brilliant engineering that went into the IQAir HealthPro Plus.
All in all, we are quite critical when it comes to air purifier ratings. That’s why it is important that we do point out the IQAir purifier has one of the highest ratings among all air purification devices:
Overall IQAir HealthPro Plus rating:
I have RUN my IQ Air purifier for 8 years now … I run it all year long… sometimes when I turn it off and forget to turn it back on for hours… MY eyes and sinuses start in… So I turn it back on and in one hour the difference is astounding.
Does this air purifier emit ozone? I read that some do, but its not listed anywhere about this one.
Hi Mel, IQAir doesn’t emit ozone. The company has several blog posts about the dangers of ozone-emitting air purifiers, all of this dangers are pretty real.
does it Pass california Prop 65?
Hi Jim, that’s a good question. IQAir company doesn’t specifically state that, however, we found this quote from the manufacturer “Since the housing of the HealthPro Plus is constructed of computer-grade ABS plastic is does not require a California Prop 65 warning.” So, it seems that it does pass the California Prop 65.
