★★★★★ 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.

FAQs
GC Series
The GC Series removes harmful gases, odors, VOCs (volatile organic compounds), smoke, and chemicals using activated carbon and chemisorption filtration. It also captures ultrafine particles down to 0.003 microns with HyperHEPA technology.
Yes. The GC Series is ideal for people with allergies, asthma, and Multiple Chemical Sensitivity (MCS). It filters both airborne particles and gases that can trigger respiratory issues.
The gas-phase filters typically last 6 to 18 months, depending on air quality and usage. The HyperHEPA particle filter can last up to 12 months under normal indoor conditions.
Yes. It effectively removes smoke particles and smoke-related gases like benzene, acrolein, and formaldehyde, making it one of the best air purifiers for wildfire smoke and tobacco smoke exposure.
No. It features an ultra-quiet mode, and even on higher fan speeds, it remains quieter than many comparable air purifiers, making it suitable for bedrooms and offices.
