A particulate air filter is a device composed of fibrous or porous materials which removes particulates such as smoke, dust, pollen, mold, viruses, and bacteria from the air. Filters containing an adsorbent or catalyst such as charcoal (carbon) or baking sodamay also remove odors and gaseous pollutants, such as volatile organic compounds or ozone. Air…
