Air filter

Device which removes solid particulates from the air

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 filters are used in applications where air quality is important, notably in building ventilation systems engine, compressor, gas turbine compressor intakes equipment(autos, aircraft, construction) cabins.
