Indoor Air Quality : 3. Air Filtration 101
Air filtration supplies the means to obtain the level of particulate cleanliness required by any definition of "air conditioning." It extends from the simple task of preventing lint and other debris from plugging heating/cooling coils to removing particles as small as 0.1 micron which could cause a short circuit on a microchip.
In addition to the reasons given above, air filters are used for a wide variety of purposes, some of which include:
Protecting the general well-being of the occupants of a space
Protecting the decor of occupied spaces by removing the staining portion of airborne dust
Reducing maintenance of building interiors by reducing the frequency of washing such as items as Venetian blinds and fluorescent bulbs
Protecting the contents of occupied spaces including paintings, tapestries, and other items of historic or cultural value
Elimination of fire hazards by removing lint and other materials which might accumulate in ductwork
Extension of shelf life of perishable dairy products by removing airborne mold during processing operations
Removing airborne bacteria from operating room air to help prevent postoperative infection.
