IQ Air GC MultiGas Air Purifier

"The GC MultiGas is the ideal system for people who are concerned about high levels of Formaldehyde, VOCs, Chemicals, and Odors. It's four “gas stage” filter cartridges put the highest-quality granulated carbon and potassium permanganate impregnated alumina pellets to work against a wide range of gases, odors, and chemicals. The “gas stage” filters utilize two-stages, Adsorption and Chemisorption, to remove pollutants. It is also effective at removing the lung irritant Ozone.

The GC MultiGas also has HEPA filtration. The H11 HyperHEPA filter delivers a minimum Total System Efficiency of 99% for particles 0.3 microns and larger and 95% for ultrafine particles down to 0.003 microns. Some air purifiers claim to be effective against gases. Others claim to be effective against particles, but the IQAir GC MultiGas integrates the best of both technologies together into a single system that provides superior filtration of gases and particles.

This is the #1 rated air purifier for those with multiple chemical sensitivity (MCS)."

The game-changing performance of the GC™ MultiGas begins with the quality of the activated bituminous-coal carbon in its gas-phase filtration cartridges. This is not the lower-cost, high-dust carbon from coconut shells that many others settle for. That's good news if you're allergic to coconut. IQAir uses only the highest grade, exceptionally porous bituminous coal for its activated carbon. And IQAir does not use zeolite, another less effective and less expensive filtration medium. The GC™ MultiGas features only the highest-quality adsorption media available. The superior activated carbon media in the GC™ MultiGas is blended with chemisorbers that target other volatile organic compounds in the air, including formaldehyde. IQAir activated carbon in the GC™ MultiGas system is complemented by pelletized aluminum oxide. The alumina pellets are impregnated with potassium permanganate, forming a powerful combination to protect you beyond activated carbon alone.

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 nimber of micropores. Only these very smallest pores in carbon filtration media are effective in removing odors and chemicals from the air you breathe, and IQAir's filters contain the maximum micropore coverage to help protect your health.

    If you are serious about your health or about your breathing, this air cleaner will change your life. my 9 year old kid suffers from severe asthma. We tried everything from different air cleaners to medicines, puffs and .... My doctor told me about IQ ai. it worths every penny. It is not cheap to buy but for us it worths it.
