WHAT ARE AIR FILTERS AND HOW ARE THEY USED
A particulate air filter is a device composed of fibrous or porous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air. High efficiency particulate air (HEPA), originally called high-efficiency particulate absorber but also sometimes called high-efficiency particulate arresting or high-efficiency particulate arrestance, is a type of air filter. Filters meeting the HEPA standard have many applications, including use in clean rooms for IC fabrication, medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE).
EFFECTS OF A DIRTY AIR FILTER
- Increased stress on blower motor parts– Higher energy bills when equipment needs to work harder
- Reduced IAQ with minimum air recirculation– If the air in your home is not recirculating, all those particles have nowhere to go except on the floor, walls and furniture.
- Overheating or freezing of equipment– Air passing thru your equipment acts like a radiator in your car to regulate the temperature. IF your system temperatures rise or fall to extreme numbers your whole home system suffers.
- Colonization of mild and mildew with little to no air flow– Mold lives in damp dark places. With limited to no moving air you run the risk of inviting mold and mildew build up.
WHEN SHOULD I CHANGE MY AIR FILTER(S)
There are many types and sizes of filters to choose from but they are not all created equal.
1″ filters– Every 1-3 months
5″ filters– Every 3-6 months
