Heating and Air Conditioning Air Filters

The term "HVAC air filter" can be generalized as any type of filter that can be placed in the return air side of an indoor unit to capture airborne contaminants. This web page is for general heating and air conditioning air filters. It was developed to give the user an array of options to find and research the correct air filter for their indoor HVAC unit. General HVAC air filters can be categorized as any air filter from disposable (standard) to HEPA filtration that properly fit your type of system. A properly sized air filter fits in a custom or OEM (Original Equipment Manufacturer) filter frame without tearing or bending, all-the-while covering all of the return air opening. The vendor's online websites, listed below, contain useful information on all types and sizes of general HVAC air filters.
