Traps ultrafine particles

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. IQAir HyperHEPA filtration in the GC MultiGas filters 95% of all particles down to 0.003 microns – the smallest particles that exist.

HyperHEPA filtration

The IQAir GC MultiGas features HyperHEPA filtration technology for excellent airborne particle removal. IQAir's HyperHEPA filtration is tested and certified by an independent third-party lab to effectively filter ≥ 95% of harmful ultrafine pollution particles down to ≥ 0.003 microns. This is 100 times smaller than 0.3 microns.

Top media, more micropores

The GC MultiGas packs the chemical removal power of more than 100 gas masks, featuring 12 lbs. (5.4 kg.) of premium activated carbon from high-quality bituminous coal provides the maximum number of micropores. Alumina pellets impregnated with potassium permanganate remove formaldehyde from the air, and post filters wrap each cylinder to further filter the air.

Smoke moving in the air

#1 For tobacco smoke

The less secondhand smoke you breathe, the better. Packing over 4,000 different chemicals, 60 of which are known carcinogens, secondhand smoke contributes to respiratory illnesses and significantly increases the risk of lung cancer and heart disease in non-smokers.
•    Note: IQAir does not endorse smoking indoors. IQAir views air cleaning as a means in reducing the effects of secondhand smoke only when smoking is unavoidable.

Multiple Chemical Sensitivity

Characterized by elevated sensitivities to household chemicals, MCS symptoms can include eye irritation, wheezing, and cough.  The GC MultiGas is rated #1 for those with MCS. IQAir systems don’t use any technologies that add MCS triggers like ozone or chemicals into the air, and are constructed of computer-grade ABS plastics that do not “off-gas”.

GC MultiGas with certificate of performance

Certified performance

IQAir looks beyond theoretical claims, testing the performance of each individual GC MultiGas system at the factory to ensure that it meets our strict specifications.

The results of the tests are detailed in a hand-signed Certificate of Performance, which is included with every air purifier. No GC MultiGas air purifier will be shipped from the factory unless it is certified to provide a minimum of 99% efficiency against particles.
