IQAir GC MultiGas Series Gas Cartridges Set of 4

This set of four gas cartridges are for use with the IQAir GC MultiGas air purifier systems. The cylindrical shape of the cartridges maximizes the surface area for optimum contact between the air and gas phase media. All of this allows them to better eliminate molecular pollutants like odor-causing volatile organic compounds (VOCs). The cartridges also destroy dangerous chemicals like formaldehyde through oxidation inside a chemically active alumina pellet.
