Carbon filters contain carbon impregnated filter fabric or granulated filter media. Carbon is a porous substance that can absorb volatile organic compounds (VOC's) on a molecular level by converting gaseous substances to a solid form and then attracting that solid to the filter. Typically, they are made with foam or fabric layers within them to hold the carbon in place and to provide a larger surface area for the obstruction of particles. One pound of activated carbon media contains a surface area of approximately 100 acres.
Carbon filters are typically referred to as "Activated". The reason is, generally, carbon is stimulated with a positive charge to allow particles to attract more easily. Carbon also has the unique property of acting as a physical filter to remove particles but also the ability to absorb chemicals, odors and smoke from the air that passes through the air purifier.
