Ultra-quiet performance
2 Filtration stages to effectively remove ≥95% of all airborne particles and odours
GC Filter Cartridges MG/S MultiGas - Stage 2
Highly effective at removing a wide range of gaseous air pollutants and odors, using a combination of granular activated carbon and chemisorption media. 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.
HEPA Pre-Filter H11 (S) - Stage 1
The HyperHEPA technology 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). Special laboratories equipped with extremely precise measure equipment (some measuring down to 0.003 µm) verified performance beyond the requirements of HEPA.
Maximum room coverage
99.9% room purification up to 1125 sq ft | 104 m²
For multiple chemical sensitivity & tobacco smoke
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.

★★★★★ No other removes smoke in the air like this one
This is an outstanding product...! I live in an apartment in NYC with a lot of chain smokers and their smoke was invading my unit to the point that my clean clothing in my closet was smelling Tabacco...Thank(s) to the MultGas air purifier; I do not smell it any more and my air is clean. 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.
