Info: Set of 4 Cartridges
S&H included in Canada. Cartridge sets for use with IQAir GC Series. In addition to trapping particulates, these VOC Cartridges (part number 102 40 10 00) are designed to have extra capacity for removing volatile organic compounds, solvents, etc. And they don't just capture VOCs, they use an oxidation process inside a chemically active alumina pellet to actually destroy certain harmful chemicals, such as formaldehyde.
Please note, when using the IQAir GC cartridges, your machine will also require IQAir's Post Filter Sleeves (which are sold separately, and are no longer available here).
