Up to 21% more clean air: The New Edition features the most powerful fan ever used in a residential room air purifier. And that power translates into even better air cleaning results. The new three-dimensionally optimized design now uses state-of-the-art aerodynamics to convert energy into more air and less noise. And by improving further on the HyperHEPA pre-filter pleating design, we were able to increase loading capacity up to 21%. This translates into higher airflow while increasing filter life – and this higher efficiency also saves you money by lowering filter replacement costs. Best media, superior performance: The game-changing performance of the GC™ MultiGas begins with the quality of the activated bituminous-coal carbon in its gas-phase filtration cartridges. This is not the lower-cost, high-dust carbon from coconut shells that many others settle for. That’s good news if you’re allergic to coconut. IQAir uses only the highest grade, exceptionally porous bituminous coal for its activated carbon. And IQAir does not use zeolite, another less effective and less expensive filtration medium. The GC™ MultiGas features only the highest-quality adsorption media available. The superior activated carbon media in the GC™ MultiGas is blended with chemisorbers that target other volatile organic compounds in the air, including formaldehyde. IQAir activated carbon in the GC™ MultiGas system is complemented by pelletized aluminum oxide. The alumina pellets are impregnated with potassium permanganate, forming a powerful combination to protect you beyond activated carbon alone. 100 Gas masks: The GC MultiGas packs the chemical removal power of more than 100 gas masks into its filter cartridges. Highest amount of micropores: The activated carbon used in IQAir GC™ MultiGas filter cartridges is activated in a way to preserve the maximum number of micropores. Only these very smallest pores in carbon filtration media are effective in removing odors and chemicals from the air you breathe, and IQAir’s filters contain the maximum micropore coverage to help protect your health. 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. Up to 20% longer filter life: IQAir’s New Edition air purifiers feature the most advanced filter-pleating pattern ever designed for a residential system. This technology not only increases airflow, but also increases particulate loading capacity by 20% on the H11 HyperHEPA pre-filter. This saves you money and reduces the frequency of filter replacements. 5-Year warranty: The IQAir GC™ MultiGas air purifier is an investment in clean air for many years to come. Like all of our air purifiers, each GC™ MultiGas air purifier is manufactured at our factory in Switzerland to demanding standards that are the highest in the industry. And each system is thoroughly tested and its performance verified before it leaves the factory (see above). As a result, IQAir is proud to cover the GC™ MultiGas in the United States and Canada for a full 5 years against defects in parts and labor. Filters are consumables and exempt from this warranty.
