ProGuard 950 is an activated catalytic carbon specially developed for removing hydrogen sulfide (H2S), and other sewage-like odors. Rated at 0.3 g/cc H2S, it boasts the highest capacity for removing H2S of any gas-phase media. It is made from coconut shell carbon, a renewable resource, and comes in 4-millimeter pellets. Our special manufacturing process eliminates the post-activation impregnation typically used. ProGuard 950’s high capacity and low density means that fewer pounds are required per unit of volume - making it the lowest cost media per pound of H2S removed.
