Air filtration units capture airborne particles such as dust, pollen, bacteria, dander, spores, etc.. Some units are non-electric media and some have combined media and electric functionality, which perform even better. Performance is measured in terms of efficiency at trapping micron-sized particles. (A human hair is 100 microns in diameter.) Removing a higher percentage of contaminants from the air may reduce the incidence of associated illnesses and allergy symptoms.

• Air filtration units mount between a furnace and the return air duct to capture airborne particles such as dust, pollen, bacteria, dander, spores, etc.. Some units are non-electric media and some have combined media and electric functionality, which perform even better. Performance is measured in terms of efficiency at trapping micron-sized particles. (A human hair is 100 microns in diameter.) Removing a higher percentage of contaminants from the air may reduce the incidence of associated illnesses and allergy symptoms.

• Media filters are a regular replacement item in whole-house filtration air cleaners. All new air filtration cleaners include one filter which should be replaced every 6 - 18 months, depending on the type of air cleaner as well as the home environment (such as if there are several pets in the home). All replacement filters offered here are original manufacturer replacements, not generic.

• Every forced air heating and air conditioning system requires a filter of some kind to protect the equipment.  These filter racks connect to the return end of the furnace or air handler, and hold the filter in place.
