Is This Air Purifier Right for Me?

If you have these air quality problems, then you need this HEPA purifier

  • Gaseous Contaminants
  • Formaldehyde
  • VOC's (Volatile Organic Compounds)
  • Hydrogen Sulfide
  • sulfur dioxide
  • airborne allergens
  • microorganisms

The IQAir GC MultiGas Air Cleaner is ideal for all living spaces, apartments, homes, bedrooms and offices. It is designed to remove a wide spectrum of gasous compounds, odors and particulates including smoke and formaldehyde by using a series of gas filters and the HEPA-type Filtration system to remove 99.5% of pollutants down to 0.003.


What is a HEPA Air Filter?

HEPA stands for High Efficiency Particulate Air. HEPA filters are made with randomly arranged fibers that trap particles as they pass through by three methods: Impaction, Interception, and Diffusion. Click here to learn more about HEPA Filters.

Standard HEPA filters can remove 99.97% of particles down to 0.3 microns in size. For comparison, human hair is around 60 microns around.

IQAir HyperHEPA filters have been proven to remove down to 0.003 microns which is 100 timers smaller than the average HEPA Purifier. This advanced cleaning technology makes this purifier the highest rated and reviewed purifier in America!


How Does it Work?

The IQAir Purifier uses 4 methods to remove 99.5% of particles:


1. PreMax™ Micro-Particle Pre-Filter:

  • Removes large particles like mold spores, pollen, dust, smoke, pet dander and allergens to preserve the HyperHEPA filter life
  • Controls the flow of coarse and fine dust particles
  • Made of 30 sqft of mini-pleat with solvent-free separators
  • 98% efficient at 5µm
  • Average Filter Life: 6-18 months

2. Cartridge-based activated carbon absorption Filter Element:

  • 10lbs of granular activated carbon
  • eliminates VOC's, solvents, & odors
  • Gas and Odor cartridge
  • Control of specific gaseous and chemical contaminants
  • Comes as a set of 4
  • Average Filter Life: 1-3 years

3. Cartridge-based Chemisorption Filter Element:

  • 17lbs of granular impregnated alumina (with KMn04 impregnated)
  • Uses an oxidation process to destroy harmful chemicals
  • oxidation process occurs within a chemically active alumina pellet
  • Housed within the Gas & Odor Cartridge listed above
  • Average Filter Life: 1-3 years

4. Micro-Charged Post-Filter Sleeves:

  • Set of Four
  • Creates sleeve for gas & Odor Cartridge to aid in removal of contaminants
  • Electrostatically charged fiber filtration
  • Eliminates post-filtration fine dust particles
  • Surface Area: 6.5 sq.ft.
  • Average Filter Life: 1-3 years


Advanced Controls


The IQAir has advanced features such as the intelligent filter life monitor that will accurately tell you when your filter needs to be replaced based on ACTUAL USAGE versus estimated time of filter life as other air cleaners use.

This will ensure that you are getting the most time and money out of your air filter to ensure maximum performance and reduce unnecessary replacement costs.


This purifier also features:

  • six fan speeds
  • automatic programming
  • a sleek remote control
  • Actual Filter Life Indicator
  • digital display


What Room Can I Put it In?

The IQAir MultiGas Air Purifier is ideal for all living spaces, apartments, homes, bedrooms and offices. If you suffer from allergies or asthma, we highly recommend you purchase one for your main family gathering area and one for your bedroom. This way you wake up feeling refreshed and always have clean air in the spaces you use the most.

Using the Highest-Quality HyperHEPA Filtration system to remove 99.5% (or better) of airborne pollutants down to 0.003, this purifier can provide serious Allergy and Asthma Relief in any room of the house!


Is it Loud?

The purifier was designed to be quiet by housing the red-label fan (highest powered in its class) inside the structure to minimize noise emmissions. This means you can put the purifier anywhere and not disturb anyone.

Decibels (dB) are used to measure sound. On the lowest setting, the IQAir is 43 decibals, which equates to the sound in a quiet bedroom at night. At the highest setting, the IQAir is 71 dB, which equates to a vacuum cleaner a few feet away.

HEPA Purifiers cannot be silent because they have to move air in order to clean the air. The IQAir has lower noise ratings than others which make it appealing to most.


How Long is the Warranty?

5 Year Warranty against all manufacturer's defects in parts and labor. Worry-Free for 5 can't beat that!

All IQAir Purifiers come with a hand-signed certificate of performance. This means that every single purifier is inspected to ensure it works as it should. This is just another reason why the IQAir is the highest rated Air Purifier in America.


Would my Insurance Reimburse me for it?

Maybe. Because the IQAir is classified a DME (Durable Medical Equipment) your insurance provider may pay you back for it. Call to be sure.

Previously reserved for multi-million dollar hospital cleanroom air purifiers, this purifier is classified (EN1822): Class H13 at 0-112cfm, MPPS efficiency: 99.95% @ 0.22µm; class H12 at 112-280cfm, MPPS efficiency: 99.5% @ 0.16µm. This is information your insurance provider might need.


Does it Produce Ozone?

No. It is 100% Ozone Free! IQAir's HyperHEPA air purification technology has been certified OZONE FREE by the IAACM (International Association of Air Cleaner Manufacturers).

The IQAir is guaranteed not to produce ozone which can be a serious lung irritant to asthma and allergy sufferers in high amounts.


How Effective is it?

Very! This home air purifier is the FIRST purifier to EVER achieve a ZERO reading on a particle counter test. This means that no particles were able to excape the HEPA filter. That's EFFECTIVE!

Advanced testing shows the IQAir Purifier effectively removes:

  • Formaldehyde
  • Hydrogen Sulfide
  • sulfur dioxide

  • smoke
  • all types of odors including pet, cooking, tobacco, paint, etc...

The American Lung Association (ALA) has been promoting lung health and educating the public about the prevention of lung disease for over 100 years while funding research opportunities to determine the cause and treatment of such diseases. The American Lung Association is one of the most highly respected and acknowledged organizations in the field of education of the public about lung health. IQAir North America has proudly been selected as an educational partner alongside the American Lung Association to help bring about awareness to the public about indoor air quality issues. As stated by John Kirkwood, President and CEO of the American Lung Association, "IQAir brings many outstanding elements to the relationship including a clear commitment to the importance of protecting the public from air pollution indoors, which can often be two to five times more concentrated than outdoor air."


In addition, President of IQAir, Frank Hammes states, "We are honored to partner with the American Lung Association. They are the world's most reputable organization committed to lung health. We share a common vision of providing superior scientific information on creating healthier indoor environments. The quality of the air we breathe indoors is critical to our health. This partnership (which combines the American Lung Associations over 100 years of knowledge about the prevention lung disease with IQAir's over 40 year commitment to air cleaning expertise) allows us to bring the public the best possible information on the importance of clean indoor air and how to achieve a healthier indoor environment."


Certified Performance


Every IQAir Air Cleaner will arrive with a hand-signed certification of performance that guarantees your air cleaner can filter 99.5% of pollutants in the air or better. The IQAir is one of the only Air Purifiers that is actually considered a Medical-Grade Purification Unit. Certified H12/13.


Ultra-Quiet Operation

The IQAir is quiet enough for your bedroom because of its advanced sound muffling features:

  • The Red-Label Fan (highest powered fan in its class) in encased within the double-walled housing structure which significantly reduces sound emission
  • The rubber suspension pads reduce motor vibration noise systematically from the housing and
  • The "Fan-In-Center" design places the fan in the center of the unit between the filters helping also to reduce the amount of noise heard by all.


Ultra-Fine Particle Removal and Molecular Absorption

Ultra-fine particles (particles smaller than 0.3microns in size) can be the most dangerous to your health because they can penetrate the tissues of your lungs and absorb into your blood stream causing serious cell damage to the mitochondria (center of the cell brain). The American Heart Association has released studies claiming they can increase the risk of heart attacks and strokes. It has also been projected that these ultra-fine particles can actually subtract 10 years from a person's life according to the California Air Resources Board.

IQAir Air Cleaners have been proven effective in removing 99.5% or higher of particles down to 0.003 microns in size. That's 100 times smaller than the average HEPA filter can filter out. In addition to removing ultra-fine particles such as pollen, dust and allergens, the IQAir can also absorb gaseous chemicals, VOC's (Volatile Organic Compounds), obnoxious odors and other molecular air pollution when upgraded to the V5-Cell (standard in all HealthPro Plus models).


Trusted World-Wide by Hospitals

Hospitals can be breading grounds for bacteria, viruses and microscopic airborne pollutants. Patients with a weakened immune system need even more protection than others from these harmful contaminants in order to recovery completely and staff needs protection from infectious disease like MRSA and Tuberculosis. IQAir is the #1 Choice for HUNDREDS of Hospitals worldwide for providing purified air. In fact, the Hong Kong Hospital Authority chose IQAir over many contenders to help prevent the spread of SARS in over 150 of there hospitals because the IQAir HyperHEPA technology is the safest and most effective way to clean the air without the use of harmful ozone, chemicals or dangerous byproducts.


Swiss Made


Made with the finest components and precision engineering in their State-of-the-art factory in Switzerland, a dedicated team of German and Swiss engineers give each IQAir Air Purifier great attention to detail during the research and development stage as well as during production ensuring superior craftsmanship.

Each IQAir Air Cleaner is HAND TESTED for reliable performance and comes with a hand-written certificate of outstanding performance. IQAir's Swiss quality assures the very best in air cleaning capabilities! Breathe cleaner air with the world's best air purification systems.


History of the IQAir

Started in 1963 by two German brothers, IQAir has remained at the front line of air purification research and development for over 45 years and are today an international, Swiss-based industry leader in the market of hygiene air purification. Manfred and Klaus created a simple filter for use in German homes to help reduce the amount of black coal build-up on the walls, however, by trapping the fine particles given off by coal burning stoves, Manfred noticed (as well as many other allergy and asthma sufferers) that it helped reduce the lung problems he had from the constant exposure to these harmful particles.

This is actually the first household air filter ever created. Soon after, the brothers designed other filters to adapt to baseboard heaters, radiators, etc..


After the death of Manfred in 1981, Klaus relocated to the current Switzerland location near the shores of the Lake of Constance and began focusing on fan-powered room air cleaners. He found a large discrepancy between effective commercial air cleaners and ineffective residential air cleaners and set out to create a blend of both worlds.

After four years of intensive research; trial and error, a team of German engineers along side Klaus finally introduced the first IQAir HealthPro Plus. It became an instance success after Europe's leading testing facility turned out incredible efficiency results for the machine during one of the most comprehensive testing events ever held. In 2000 the IQAir HealthPro Plus was launching in the United States and became America's favorite air cleaner to help relieve asthma and allergy symptoms.

Since then, IQAir's innovative manufacturing has continued to develop even more advanced versions of the HealthPro Plus along with other models including the Gas series and the HealthPro Compact.

    • In 2002, IQAir became the only room air purifier to ever receive the certification as a H12/13 Medical device for it's HyperHEPA filters, previously, only multi-million dollar purification systems were classified so highly.


    • In 2003, SARS, a highly contagious, terrifying disease caused by a corona virus spread rapidly through Hong Kong affecting thousands of people's respiratory systems. After vigorous testing by the Hong Kong Hospital Authority, IQAir was the only air purification system chosen to supply room air cleaners to over 150 hospitals to fight the spread of the disease.


    • In 2004, The American Lung Association chose IQAir to become an educational partner to help educate the public on Indoor Air Quality issues. Over the course of 2004, numerous tests and reviews were published about the IQAir's effectiveness and superiority from Consumer's Digest Magazine, Reviewboard Magazine, Allergy Buyers Club and Consumer Search giving it top ratings across the board.


    • In the summer of 2004, IQAir is approached by the producers of ABC's award winning TV show Extreme Makeover-Home Edition requesting IQAir to help create America's Healthiest Home for a 6 year old in need of medically pure clean air. This makes TV history and began a series of episodes installing the IQAir in the homes of families with severe medical needs. Again, the American Lung Association honors IQAir for it's performance.


  • Today, although now retired, Klaus remains an advisor to the family business ensuring the continued effort of IQAir's research and development team to remain industry leaders in the air purification field of hygiene medical equipment.

    Got rid of smoke right away, like a smoke eater!

    Posted by Justin on 19th Mar 2012

    We have had a problem with neighbors smoking in our apartment complex for years...smoking everything. The smell was terrible and we were tired of dealing with our clothes smelling like pot or cigarrette smoke. This purifier worked right away at removing smoke and the odor associated with it. Anyone struggling with smokers in an apartment near by should give this purifier a try. I'm highly convinced this machine was sent from God. :)
