How many filters does it use?

The IQAir HealthPro Plus uses a set of three filters, which provides for a 4-stage filtration process which cleans the full spectrum of airborne pollutants. Each of the three filters are manufactured by IQAir in Switzerland to be the very best in each category.

Hyper-HEPA Filter (F3)
Stage 4 - HyperHEPA Filtration. IQAir's HyperHEPA filter is tested and certified to filter dust particles down to 0.003 microns (the world's smallest particle) with a guaranteed minimum efficiency of over 99.5%. This is 100 times better than what can be achieved by ordinary HEPA technology. The Hyper-HEPA filter eliminates bacteria, viruses and combustion particles from automobiles and smoke through a nano-fiber structure. HyperHEPA filtration technology is the safest, healthiest and most effective way to clean the air. Air is filtered with no ozone, no ions, no UV, no chemicals or any other unhealthy byproducts. Unlike the HEPA filters used in conventional air cleaners, the IQAir HyperHEPA filter is manufactured to such a high quality standard that it conforms to the most stringent hospital and cleanroom requirements.

V-5 Cell Gas and Odor Filter (F2)
Stages 2 and 3 - Granular Activated Carbon Adsorption and Pelletized Chemisorption. Patented V5 filtration provides the best solution for gas and odor elimination. The V5 filter combines two types of media - one that adsorbs odors and gases, and another media that changes the pollutant to an oxidized form. Granular activated carbon adsorption eliminates volatile organic compounds (VOC), which are responsible for odors. Pelletized chemisorption destroys harmful chemicals such as formaldehyde by an oxidation process inside a chemically active alumina pellet.

PreMax Prefilter (F1)
Stage 1 - Micro-Particle Filtration. While most air purifiers use small prefilters with particle efficiencies well below 20%, the large, commercial-sized super-efficient IQAir PreMax prefilter typically retains over 90% of coarse and fine dust. The PreMax prefilter is thus the most efficient pre-filter of any household air purifier, allowing the Hyper-HEPA filter and V5-Cell to last up to 5 times longer than similar filters in ordinary air purifiers.

* filter life can vary based on actual usage and pollution levels.


How is the HyperHEPA filter better than ordinary HEPA filters?

Ultrafine Particles:
Ultrafine particles are smaller than 0.1 microns. By sheer number, about 90% of all airborne particles are this size. The primary source of ultrafine particles is combustion from motor vehicles, refineries, industrial plants and even cooking. Viruses are also ultrafine particles. The small size of ultrafine particles enables them to be easily inhaled, deposited into the lungs and absorbed into the blood. They have been linked to heart attacks, strokes, asthma and even cancer.

Manufacturers of ordinary air filtration systems claim only that their systems filter particles larger than 0.3 microns. IQAir is different. IQAir’s HyperHEPA filtration is proven and certified to filter up to 99.5% of all particles down to 0.003 microns – the smallest particles that exist. Independent testing by laboratories and government agencies verifies the effectiveness of IQAir technology against ultrafine particles. When it comes to protection against ultrafine particulates, IQAir is the proven choice.

100x more filtration than ordinary HEPA:
Unlike other air purifiers, IQAir's HyperHEPA filtration system is proven to stop the smallest, most harmful particles in the air, all the way down to 0.003 microns – the smallest particles that exist. That includes viruses, pet dander, dust mites, air pollution and even cigarette smoke. IQAir uses nanofiber technology and innovative design to stop particles 100 times smaller than what other air purifiers claim. We don't just claim it, we prove it in rigorous independent testing.


Are the filters washable?

The filters in the HealthPro Plus are designed to be replaced when the end of their usable life has been reached. Filters that are washable or cleanable are not nearly as effective as replaceable filters. In addition, the HealthPro Plus requires absolutely no regular maintenance such as weekly or monthly cleaning, so you can stop worrying about maintaining and cleaning your air purifier, and just enjoy the peace of mind that comes with knowing you have the best air purifier in the world cleaning your family's air.


How long do they last?

The HyperHEPA filter lasts up to 4 years, the V-5 Cell Gas and Odor Filter up to 2 years, and the PreMax Prefilter lasts up to 18 months. These estimates assume average usage for 10 hours per day on speed 3. Your actual filter life will vary based on usage and environmental conditions.


How do I know when they need to be changed?

Each filter has its own dedicated indicator light to let you know when it needs changing.


How much do the replacement filters cost?

On average, the annual filter replacement cost will be around $200, or less than 60 cents/day. A unique feature of IQAir filters is that even when the lights are red and require a filter change, they are still fully efficient (unlike other brands which require very frequent filter changes to maintain their claimed efficiency).
