Air filter
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.
- human-made environments (e.g., satellites, and Space Shuttles)
Air filters are typically constructed of foam, pleated paper, cotton, or spun fiberglass. Oil bath air filters have fallen out of favour aside from niche uses.
Air ionizers use a different method, static electric charge, than air filters to attract and remove dust particles but they may also be supplemented with an air filter.

Baghouse
[edit | edit source]
A baghouse also known as a fabric filter dust collector is an air pollution control device that removes particulates rom a gas stream. Baghouses are often employed in large industrial applications such as power generation, steel mills, chemical production and manufacturing plants to capture air pollutants generated during normal operation. In many countries environmental regulation essentially mandates the installation and operation of a baghouse system achieve a reduction of hazardous air emissions from industrial sources.[1] Additionally, in some instances the baghouse functions to recover product as part of the industrial process such as by collecting precious metals or pharmaceutical dusts created during manufacturing. Baghouses are also used for workplace safety purposes such as the prevention of combustible dust explosions[2] and reducing worker exposure to harmful compounds.[3]
