  • The GC MultiGas is IQAir's best seller for individuals with multiple chemical sensitivity (MCS) and controls a wide range of gaseous organic and inorganic chemicals.
  • The National Institute of Environmental Health Sciences (a division of the NIH) defines MCS as a "chronic, recurring disease caused by a person's inability to tolerate an environmental chemical or class of foreign chemicals".
  • The GC MultiGas is IQAir's best seller for individuals with multiple chemical sensitivity (MCS) and controls a wide range of gaseous organic and inorganic chemicals.
  • IQAir systems follow a long European design tradition. They feature a bold, yet timeless design, which adapts beautifully to any home, whether contemporary, modern or traditional.
  • Air is drawn in at the bottom of the air cleaner and passes through a series of filters. 100% filtered air is then expelled out of the top of the air cleaner. With it's air intake and outlet at opposite ends, recycling of filtered air is eliminated.
  • First, the HEPA class H11S pre-filter eliminates micro- and nano-particles such as mold,  allergens, smoke, bacteria and viruses.
  • Next, air moves through the cleanroom grade sealed fan and motor system which doesn't have a negative impact on the air. It is in the center, allowing the filters to absorb sound. Ball bearings and shock absorber make this unit extremely quiet on low.
  • All of our units have been upgraded to the improved "Red Label" fan system and feature all the latest upgrades.
  • Third, the air moves through 4 Cartridge-based Activated Carbon Absorption that eliminates VOC's which are responsible for odors.
  • The 4 cartridges contain 12 lbs of granular activated carbon also features cartridge based chemisorption which destroys harmful chemicals.
  • Finally, the air passes through Micro-charged Filtration (post filter sleeves) which elimates activated carbon and chemisorption abrasion particles through a statically charged fiber struction.
  • Most air cleaners return the air through a small outlet, which creates annoying air drafts. IQAir systems are designed to avoid drafts by evenly returning cleaned air through a large 320° vented diffuser.
  • The efficiency stated for most air cleaners is theoretical. Internal leakage drastically reduces efficiency. IQAir features patented triple sealing technology and have actual system efficiency higher than the theoretical efficiency of other air cleaners.
  • IQAir inspectors evaluate every component that goes into the air purifier. If a component does not meet IQAir's strict criteria, the part is not used in the purifer and discarded.
  • EMC (Electromagnetic Compatability) testing for medical device safety approval.
  • IQAir individually tests each air purifier to ensure that its performance meets our strict specifications. The results of the tests are detailed in a hand-signed Certificate of Performance, which ships with every room air purifier.
  • Ordinary air cleaners have you guess when to replace filters or use a preset timer. IQAir’s intelligent filter life monitor takes actual use, speed settings and air quality conditions into account to determine filter changes.
  • Convenient remote control sets fan spead, timer and on/off.
  • IQAir has earned the distinction as the official partner with the American Lung Association for indoor air quality education.

Product Description:

All of our IQAir purifiers come standard with the improved "Red Label" fan system for quieter operation and increased clean air delivery and feature all the latest upgrades.

Gas Cartridge Technology

The cylindrical shape of these cartridges allows for optimum contact between the air and the gas phase media, while offering low air flow restriction.

The cartridges are very user friendly and can be replaced in a matter of minutes.

Interchangeable Cartridges

As your air purification needs may change over time, all of IQAir's Gas Cartridges within the GC Series are all interchangeable, making these purifiers the most user friendly systems in the world.

Micro- and Nano-particle Filtration (HEPA)

Eliminates micro- and nano-particles such as allergens, smoke, bacteria and viruses. This thorough particle pre- and post gas cartridge filtration is essential for extending the life of the gas phase control media by preventing its pores from clogging with particulates. It also results in total system filtration efficiency greater than 99% for particles ≥0.3 microns in size.

Advanced Controls

The IQAir control panel allows you to select from six different fan speed settings. A two-line LCD displays the corresponding air delivery rate at each speed setting. A sophisticated filter life monitoring system calculates the remaining life of each individual filter. An integrated timer allows to program the unit for automatic operation. For added convenience, the GC units also come with a remote control.

Average Filter Replacement Schedule

Based on 10 hours usage per day on speed setting 3.
* PreMax Filter: 6-18 months
* Gas and Odor Filter: 1-3 years
* Post-filter Sleeves: 1-3 years

The IQAir Warranty
