IQAir GC MultiGas Awards and Reviews:

Cigar Aficionado Magazine
“We tested the GC MultiGas in less-than-laboratory, but smokier-than-average conditions in the Cigar Aficionado offices, and found it performed admirably under strain. The unit quickly cleared smoke out of a small office, and soon after the traces of cigar were unnoticeable.”
Reviewboard Magazine’s “Editor’s Choice” Award 2004
“So if you are looking for the best air filtration systems for your home then the folks at IQAir have what you are looking for.” “Both of these units, HealthPro 250 and GC MultiGas are top of class, they filter and push more air around your living space than any other machine we have ever tested in the eight years we’ve been in business here at Reviewboard Magazine.”

  1. 1. Micro-Particle Filtration
    Through the high-efficiency GC HEPA Pre-Filter, for capturing large particle pollution (such as dust, traffic pollution, pollen, pet dander, dust mite and mould allergens). The pre-filter of the GC MultiGas air cleaner consists of a high-capacity mini-pleat design with solvent-free separators and a CFC-free construction. The media of the filter is a non-woven glass microfiber and has an efficiency of 99% at 0.3 μm (class H11). The large surface area of the GC MultiGas Pre-Filter, in combination with the leakage free design of all IQAir air purifiers, protects the fan and subsequent filters from large particle pollution and premature loading.

    2. Odour and Gas Elimination
    Through the GC MultiGas Cartiridge-Filter Set, which consists of four gas and odour control filter cartridges that work simultaneously to filter a broad range of gaseous and chemical substances. The filtration technology of the GC MultiGas eliminates a broad spectrum of gaseous pollutants and odours, including VOCs. This is achieved through a 5.4kg of wide-spectrum media mix of granular activated carbon and KMn04 impregnated alumina. The large surface area of the GC Filter Cartridge Set enables a high airflow rate, and in combination with the leakage free construction, the GC MultiGas is the most efficient air purifier for odour, chemical and gas removal.

    3. Fine Dust Removal
    The GC Post-Filter Sleeve Set provides the final filtration stage of the GC MultiGas. The four post-filter sleeves are electrostatically charged fiber filters that capture fine dust particles. This eliminates activated carbon and chemisorption abrasion particles. Each of the cartridges of the IQAir GC Series operate in unison to meet almost any moderate gas phase removal needed in residential or commercial environments.

IQAir GC MultiGas Air Purifier

Haven't really had chance to use it yet, but looks like it will be perfect. A little noisy on the higher settings but they will perfect to use on the timer when not in work. So far very pleased.

Ordered IQiar MultiGas. Seems to work well. Delivered within 48 hours. The engineer came out to assemble the same day. Have had a IQAir 250 unit for years. Had to change the prefilter once! Even though they are very expensive but you get what you pay for .
