The HART COOLEY 276200200 is a disposable fiberglass air filter designed for use in residential and light commercial HVAC systems. Measuring 20 inches by 20 inches by 2 inches, this filter installs in standard return-air filter slots or filter grille frames to capture airborne particulates and protect downstream equipment. Fiberglass media provides low-resistance airflow suitable for systems where maintaining static pressure drop is a priority. HVAC technicians and property maintenance professionals typically install this filter as part of routine preventive maintenance.
This filter is suited for forced-air heating and cooling systems that accept a 20 x 20 x 2-inch filter size. Typical installations include residential gas furnaces, heat pumps, and air handlers with matching filter compartments. It is sold individually, making it practical for single-unit replacements or stocking in small quantities.
Designed as a direct-fit replacement for residential and light commercial HVAC systems requiring a 20 x 20 x 2-inch disposable air filter.
Installation is performed by HVAC technicians or qualified maintenance personnel. Always set the system thermostat to the off position and shut down the air handler or furnace before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Dispose of the used filter in accordance with local waste disposal guidelines.
