Connect the GC MultiGas XE to the AirVisual app to monitor air quality, check PM2.5 data, and control purification modes directly from your phone
Real-time air quality tracking and app integration
Removes even the smallest airborne particles, and the Pre-Max extends the life of the filters
HyperHEPA & Pre Max Filters
The GC XE Series provides soft, low decibel sound across all fan speeds.
Ultra-quiet performance
Filters volatile organic compounds (the cause of odors) and other harmful chemicals like formaldehyde.
V5 Cell Granular Activated Carbon
2 Filtration stages to effectively remove ≥99.5% 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.
GC HEPA Pre-Filter H11 (S) - Stage 1
The HyperHEPA technology has been tested and shown to remove ≥99.5% 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.
Air Purification
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.
Effective purification for medium to large size rooms.

Comprehensive filtration for gases, odours & ultrafine particles with HyperHEPA technology
HyperHEPA Filtration
Though the GC MultiGas system focuses on gases, it’s typically used with IQAir’s HyperHEPA filter, which captures particles down to 0.003 microns—ultrafine particles most other purifiers miss.This combination delivers comprehensive filtration: gases, odors, and ultrafine particles (PM2.5, PM0.3, viruses, allergens, etc.).
MultiGas Cartridge Filtration
Each GC MultiGas system contains four large gas filter cartridges with activated carbon and chemisorber media. The cartridges are designed for maximum airflow and surface contact. This modular configuration enhances gas-phase filtration performance, increases filter life, and ensures consistent removal of chemical fumes, smoke, and harmful gases from indoor environments.
Long-lasting filters with high adsorption capacity
IQAir GC and GC XE MultiGas filters are engineered for durability, with a high-capacity design that allows for 6 to 18 months of consistent use under normal indoor conditions. The generous amount of filtration media ensures long-term protection from gases and odors without frequent replacements, making it a cost-effective air purifier filter solution.
GC XE and the IQAir AirVisual app
IQAir's AirVisual app is the world’s number one air quality app! The apps integration with our air purifiers offers advanced functionality for optimizing indoor air quality. Through the AirVisual app, users can connect to compatible IQAir purifiers to monitor and control air quality remotely. Features include real-time updates on indoor and outdoor air pollution, air quality forecasting, and the ability to adjust purifier settings, such as fan speed or filter usage, directly from a smartphone.
Enhanced with a redesigned energy-efficient fan, WiFi smart app integration, sensor-based smart modes, and real-time PM2.5 measurement.
★★★★★ Overall rating 4.8 (179) reviews
The air purifier trusted by allergy sufferers, mcs patients & professionals worldwide
★★★★★ Fantastic
This machine makes an enormous difference in our indoor air quality. It eliminates the off gassing odors of our new apartment. I need to leave it on the highest or next to highest setting when we’re home and using the main living area. When sleeping I can have it on a medium (a more quiet) setting and it works great with the bedroom door shut.
– ERobbins Atlanta, GA Verified Purchaser
★★★★★ Outstanding
This unit is outstanding. It effectively clears the air and maintains indoor air quality. Unfortunately, I had to purchase this unit due to the recent fires in Los Angeles County as I live in a fire zone. I own multiple IQAir products, and all of them have been exceptional.
– Otterhse Verified Purchaser
★★★★ These filters have helped my health so much.
They last and every time I change the filters it's like having a brand new unit again. I have multiple chemical sensitivities and multiple other allergies. I have 3 units scattered in my house and it has helped me so much.
