Description / Abstract:

This standard applies to factory-made Air Filter Equipment and Air Filter Media, as used in such equipment, for removing particulate matter, when used in environmental conditioning of inhabited spaces in residential facilities. The standard evaluates the “combined” performance of Air Filter Equipment in all aspects: Initial Resistance, Final Resistance, Particle Size Efficiency, and Dust Holding Capacity. This offers both the user and specifier a complete view of the Air Filter Equipment for comparison purposes.

Exclusions. This standard does not apply to the following:

Air Filter Equipment and Air Filter Media for removing particulate matter, when used in industrial or commercial processes not associated with environmental conditioning of inhabited space.

Air Filter Equipment when used in removing abnormally high concentrations of specific contaminants.

Portable appliances which include Air Filter Equipment in combination with fans, coils, dampers, etc., but can be applied to the Air Filter Equipment as used therein.

Commercial and industrial Air Filter Equipment covered by AHRI Standard 850 (I-P).

Purpose. The purpose of this standard is to establish for residential Air Filter Equipment: definitions; classifications; test requirements; rating requirements; minimum data requirements for Published Ratings; operating requirements; marking and nameplate data; and conformance conditions.

Intent. This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors and users.

Review and Amendment. This standard is subject to review and amendment as technology advances.
