  Respirators are facial masks that are specifically designed to protect an individual from inhaling certain gases and vapors that can be harmful or deadly. According to the Medical Dictionary website, a respirator with a HEPA filter "reduces particulate matter more effectively than simple isolation masks." The Gemper website explains that HEPA cartridge filters are treated with activated carbon, which absorbs gases and vapors.
