The HART COOLEY 102700021 is a pleated furnace air filter rated MERV 8, designed to capture airborne particles in residential and light-commercial forced-air HVAC systems. Measuring 20 inches by 25 inches by 2 inches, it fits standard filter slots in gas and electric furnaces, air handlers, and central cooling systems. The pleated media construction increases surface area relative to flat-panel filters, supporting adequate airflow while trapping dust, pollen, mold spores, and similar mid-range particulates. Licensed HVAC technicians and qualified service personnel install this filter as part of routine preventive maintenance.
This filter is suited for residential gas furnaces, electric furnaces, and central air handler units with a 20 x 25 x 2 inch filter rack. MERV 8 filtration is a common specification for residential applications where occupant comfort and equipment protection are the primary goals. It provides a balance between particle capture efficiency and static pressure drop, making it appropriate for standard residential blower systems without high-efficiency variable-speed motors.
Designed as an OEM-style replacement pleated air filter for residential and light-commercial forced-air HVAC systems using a standard 20 x 25 x 2 inch filter slot.
Filter replacement is performed by licensed HVAC technicians or qualified service personnel. Before replacing the filter, set the thermostat to off and shut down the furnace or air handler at the system switch or breaker to prevent debris ingestion during service. Install the filter with the airflow arrow on the frame pointing toward the blower. Follow local codes and manufacturer service intervals for replacement frequency.
