Certified performance
Because our design and manufacturing standards are so high, IQAir individually tests each GC™ MultiGas air purifier at the factory to ensure that its performance meets our strict specifications.

The results of the tests are detailed in a hand-signed Certificate of Performance, which is shipped in the box with every air purifier. Your GC™ MultiGas air purifier will not be shipped from the factory unless it is certified to provide a minimum of 99% efficiency against particles.
