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.

★★★★★ 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.
