IQAir MultiGas GC Replacement Filters

IQair logo

The IQAir MultiGas GC™ air purifier uses an H11S pre-filter [1] designed to last for 6 to 18 months, and four post-filter sleeves [3] that wrap around each gas cartridge, designed to last for 1 to 3 years. The exact lifespan of each filter depends on the concentration of contaminants in the room.

Each air purifier in the IQAir GC Series also uses four gas phase filter cartridges [2], which require replacement every 1 to 3 years.

IQAir’s Intelligent Filter Life Monitor takes the guesswork out of filter replacement by indicating the status of each individual filter and when it needs to be changed.
