Air filters are used in application where air quality is important, notably in building ventilation systems and in engines, such as internal combustion engines, gas compressors, diving air compressors, gas turbines and others.

Some buildings, as well as aircraft and other man-made environments (e.g., satellites and space shuttles) use foam, pleated paper, or spun fiberglass filter elements. Another method uses fibers or elements with a static electric charge, which attract dust particles. The air intakes of internal combustion engines and compressors tend to use either paper, foam, or cotton filters. Oil bath filters have fallen out of favor. The technology of air intake filters of gas turbines has improved significantly in recent years, due to improvements in the aerodynamics and fluid-dynamics of the air-compressor part of the Gas Turbines.

Air Condition / Heater Filter

Heat & Cool Efficiently

As much as half of the energy used in houses goes to heating and cooling. So making smart decisions about home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on utility bills.

Changing Air Filters

Energy Star advises air filters be checked every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, it should be changed. The air filter should be changed at least every 3 months. A dirty filter will slow down air flow and make the system work harder and use more energy to warm or cool. Improper air flow can cause air conditioning components to freeze. A clean filter will also prevent dust and dirt from building up in the system which can lead to expensive maintenance and/or early system failure.

Climate control air filters

There are four main types of mechanical air filter media: paper, foam, synthetics, and cotton.

Air filters are found in most all forced-air heating, ventilation, and air conditioning systems. The efficacy of the air filters in such systems significantly affects the Indoor Air Quality. The United States Department of Energy advises that " Filtration should have a Minimum Efficiency Reporting Value (MERV) of 13 as determined by ASHRAE 5.2.2-1999." There are a variety of different types of HVAC filters available. Many are inexpensive and not very efficient. Some options are panel, pleated, electrostatic, HEPA, electronic and media. ASHRAE recommends (MERV 6 or higher) air filters to lower the amounts of pollen, mold and dust that reaches the wet evaporator coils in air conditioning systems. Wet coils contaminated with high levels of pollen and dust can allow mold colonies to grow.
