Features
Gas Filtration Meets Chemical Protection
The GC AM is designed to address complex indoor air pollution caused by chemicals, gases, and odors. From volatile organic compounds (VOCs) to smoke and off-gassing materials, it delivers targeted protection for environments where gaseous pollutants are a primary concern.
Advanced Gas Filtration
A high-capacity system using 22lbs of activated carbon and specialized media targets a wide spectrum of airborne chemicals, including VOCs, ozone, and other gaseous pollutants.
High Adsorption Capacity
Engineered with a large volume of filtration media, the system provides long-lasting protection against persistent odors and chemical exposure.
Two filtration stages to effectively remove gases and odors, and ≥99% filtration efficiency for particles ≥0.3 µm
GC HEPA Pre-Filter H11(S) - Stage 1
The GC HEPA Pre-Filter H11(S) has been tested and shown to remove ≥95% of all airborne particles, including those particles down in the ultra-fine particle size range (<0.1 µm in diameter).*
Total system efficiency for the air cleaner is individually tested and certified at the factory to achieve ≥99% filtration efficiency for particles ≥0.3 µm.
GC AM Cartridges - Stage 2
Highly effective at removing a wide range of gaseous air pollutants and odors, using a combination of chemisorption media and 22lbs of granular activated carbon. This effectiveness comes from both the quantity and quality of the filtration media used, which far exceeds what’s found in typical consumer-grade air purifiers.
Maximum room coverage
99.9% room purification up to 1125 sq ft
For multiple chemical sensitivity & airborne bacteria
Built to remove airborne chemicals, bacterial particles, viruses, and gaseous emissions through advanced medical-grade filtration.
A layered blend of activated carbon and proprietary media tailored to adsorb a wide spectrum of gaseous pollutants, including volatile organic compounds (VOCs), ozone, and various chemical fumes.
Removes allergens, bacteria, viruses, mold spores, harmful dust, smoke, PM2.5, PM10, and other fine and ultrafine particles and particle-bound odors.
Effective purification for medium to large size rooms.

It works like a miracle.

★★★★★ Formaldehyde Nightmare
Don't waste your money on any other if you have any inkling of a VOC issue because I spent thousands on others that didn't cut the gas. I had 3 in the main room even that could not do what one IQ Multigas did.g.

★★★★ Best air filter I know
We bought an IQAir 14 years ago. It worked extremely well but naturally performed less over time. It was slightly more expensive to replace the filters than to buy a new unit, so we bought a new GC MultiGas. I waited so long due to the high cost. Just like before, the air quality is outstanding and has helped my wife's allergies.
