This is the Indy race car of air purifiers.





Up to 21% more clean air

The New Edition features the most powerful fan ever used in a residential room air purifier. That power translates into even better air cleaning results. The new three-dimensionally optimized design now uses state-of-the-art aerodynamics to convert energy into more air and less noise. By improving further on the HyperHEPA® pre-filter pleating design, we were able to increase loading capacity up to 21%. This translates into higher airflow while increasing filter life. This higher efficiency also saves you money by lowering filter replacement costs.

Fine and ultrafine particles on IQAir filter fibers.

Proven performance against 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.

100 Gas masks

The GC MultiGas packs the chemical removal power of more than 100 gas masks into its filter cartridges.

Highest amount of micropores

The activated carbon used in IQAir GC MultiGas filter cartridges is activated in a way to preserve the maximum number of micropores. Only these very smallest pores in carbon filtration media are effective in removing odors and chemicals from the air you breathe. IQAir's filters contain the maximum micropore coverage to help protect your health.

Certified performance

Because our design and manufacturing standards are so high, IQAir individually tests each GC MultiGas air purifier at the factory to ensure that its performance meets our strict specifications.  The results of the tests are detailed in a hand-signed Certificate of Performance, which is shipped in the box with every air purifier. Your GC MultiGas air purifier will not be shipped from the factory unless it is certified to provide a minimum of 99% efficiency against particles.

Up to 20% longer filter life

IQAir’s New Edition air purifiers feature the most advanced filter-pleating pattern ever designed for a residential system. This technology not only increases airflow, but also increases particulate loading capacity by 20% on the H11 HyperHEPA pre-filter. This saves you money and reduces the frequency of filter replacements.

Multiple Chemical Sensitivity

As many as 15% of Americans, or about 46 million people, suffer from Multiple Chemical Sensitivity (MCS), characterized by elevated sensitivities to household chemicals and commercial products. Symptoms can include eye irritation, wheezing, fatigue, rhinitis, sore throat or cough, skin rashes and other symptoms. The best strategy for treating MCS is to avoid the airborne contaminants and chemicals that trigger the illness and reactions. Because indoor air pollution concentrations are typically much higher than outdoor air pollution levels, “air-filtration devices that remove both particulate and chemical substances from breathable indoor air usually benefit MCS patients considerably,” one leading medical expert concluded.

Reviewers rate IQAir air purifiers as the best systems available for MCS sufferers. Most other air purifiers simply are not effective enough to make a real difference in the quality of the air an MCS sufferer breathes. Equally important, IQAir does not use any technologies that add additional MCS triggers into the air, such as ozone or chemicals. And IQAir products are constructed of computer-grade ABS plastics that do not “off-gas” into the air.
