    The IQAir GC MultiGas (HP-MULTIGAS) air purifier offers exceptional protection against a broad spectrum of airborne contaminants to provide relief for people with severe gas, odor and chemical sensitivities. This industry leading, top-of-the-line system combines premium grade filtration elements with user-friendly features and accessories to deliver unparalleled system functionality and ultra pure air quality to allergy and MCS (multiple chemical sensitivities) sufferers.

    Designed and built in Switzerland, the MultiGas system is a 4-stage system that utilizes a premium blend of bituminous coal activated carbon to effectively remove harmful gases, odors and chemicals such as volatile organic compounds. High-grade alumina pellets are impregnated with potassium permanganate to effectively remove formaldehyde from the air. For micro and nano-particles, the MultiGas system features a HEPA pre-filter that delivers a system efficiency of 99% or more for all particles 0.3 microns or larger.

    The GC MultiGas also offers a host of features and accessories to deliver exceptional value, convenience and functionality. A LCD control panel provides detailed information on air flow speed, area coverage and filter cartridge status. To cut down on energy costs and extend filter life, a programmable day/night auto timer allows you to set specific periods of time when you want the system to run. The handy remote control allows you to power on the system, adjust all 6 fan speeds, and activate timer controls from up to 20 feet away.

    To guarantee system efficiency, the MultiGas utilizes a patented knife-edge seal design form at the filter media, cartridge and housing frames to ensure an air-tight seal which reduces the chance of internal leakage. The result is ultra-pure, clean air free of chemicals, VOCs, formaldehyde and airborne particulates.

Performance & Specification

    Better Media & Design = Superior Performance

    The GC MultiGas system uses only the highest grade, ultra-porous bituminous coal for its activated carbon gas-phase filtration cartridges. This select media is blended with chemisorbers that target chemicals and volatile organic compounds in the air, including formaldehyde. The addition of aluminum oxide pellets impregnated with potassium permanganate offers additional protection beyond what is available with activated carbon alone.


    Air Filter Diagram

    The GC MultiGas system uses patented 3D Ultraseal technology to deliver perfect knife-edge-in-groove sealing between the filter frame and housing. This ultra precise design form ensures that the vast majority of harmful chemicals and pollutants are trapped in the filters and not leaked back into circulation, the main problem with most systems on the market.

    High Performance System Components:

    1st stage

    HEPA pre-filter removes micro particles such as allergens, smoke, bacteria and viruses.

    2nd stage

    Gas & Odor Filters (set of 4) contain cartridge-based activated carbon media that adsorbs volatile organic compounds (VOC) while chemisorption media destroys a while range of chemicals through the process of oxidation.

    3rd stage

    Post-Filter Sleevess (set of 4) allow micro-charged filtration that eliminates carbon & chemisorption abrasion particles through a charged fiber structure.
