Proven to stop ultrafine particles

Ultrafine particles are smaller than 0.1 microns, and make up about 90% of all airborne particles,  originating from combustion from vehicle exhaust, factory emissions, and cooking. They have been linked to heart attacks, strokes, asthma, and even cancer.

IQAir’s HyperHEPA filtration in the GC MultiGas is proven and certified to filter at least 95% of all particles down to 0.003 microns – the smallest particles that exist. 

When it comes to protection against ultrafine particulates, gases, and odours, IQAir is the proven choice.

See why particle size matters...

HyperHEPA filtration

The IQAir GCMultiGas features HyperHEPA filtration technology for superior airborne particle removal. IQAir's HyperHEPA filtration is tested and certified by an independent third-party lab to effectively filter ≥ 99% of harmful ultrafine pollution particles down to ≥ 0.3 microns. This is 100 times smaller than what is achieved with ordinary air filtration technology and 10 times smaller than a virus.

The best media, more micropores

The GC MultiGas packs the chemical removal power of more than 100 gas masks.

The four disposable gas-phase filter cartridges of the GC MultiGas feature 12 lbs. (5.4 kg.) of premium activated carbon from bituminous coal to preserve the maximum number of micropores. The cylindrical shape of the GC MultiGas cartridges allows for optimal contact between the air and the filtration media, while offering very low air restriction.

Alumina pellets impregnated with potassium permanganate remove formaldehyde from the air. Meanwhile, post filters wrap each cylinder, preventing any media dust from being released while further improving efficiency.

Smoke moving in the air

#1 Rated 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.

Most experts recommend the GC MultiGas air purifier for its unrivaled protection against the particles and gases found in smoke. 

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. In an environment where smoking indoors in unavoidable, smoking should be confined to only one room.

Multiple Chemical Sensitivity

Many individuals suffer from Multiple Chemical Sensitivity (MCS), characterised by elevated sensitivities to household chemicals. Symptoms can include eye irritation, wheezing, and cough. 

The GC MultiGas provides real protection that can help you feel better. That’s why the GC MultiGas is rated #1 for those with MCS.

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.

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.
