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.

IMPORTANT NOTE:  Unfortunately, IQAir is not bulk shipping filters to dealers until Covid is under control. In the meantime, IQAir filters can be purchased directly from IQAir North America on their website We look forward to once again being your Canadian source for IQAir filters once things return to normal.
