SAAFCarb enhanced capacity media efficiently removes 99.5% of targeted contaminants from SAAFCarb systems. Target impurities include diesel fumes (nitrogen dioxide), hydrocarbons, chlorine, and volatile organic compounds (VOC). The pelletized activated carbon is composed of non-toxic, bituminous coal substrate. SAAFCarb media removes toxic and impure gases from the environment by adsorption. In this process, the gases accumulate on the surface of the pellet.
