The PRO-SOURCE PRO21269 is a MERV 8 pleated air filter rated for residential and light commercial HVAC applications. Built with a synthetic media and a paperboard frame, it delivers 35% particle capture efficiency at a rated airflow of 1,650 CFM and a maximum face velocity of 500 FPM. The nominal size is 20 x 24 x 2 inches, with actual dimensions of 19-3/8 x 23-3/8 x 1-3/4 inches. Initial resistance is 0.23 inches water gauge at 500 FPM, with a final resistance of 1.0 inch water gauge. The filter meets ASHRAE 52.2-2012 and UL 900 standards and is rated for temperatures up to 150 degrees F. HVAC technicians and mechanical contractors install this filter as a direct drop-in replacement in standard filter slots.
This filter is suited for use in forced-air heating and cooling systems where a standard 20 x 24 x 2 inch filter is required. The MERV 8 rating makes it appropriate for residential homes, apartment buildings, and light commercial spaces where moderate filtration of dust, pollen, mold spores, and lint is the primary goal. The wireless pleated design maintains consistent airflow across the filter face without a center wire support, which simplifies changeout and reduces debris during removal. Per the supplier data, this filter is compatible with any unit accepting the nominal 20 x 24 x 2 inch size.
Designed for use with any HVAC unit accepting a nominal 20 x 24 x 2 inch pleated filter. Verify actual filter slot dimensions against the actual size of 19-3/8 x 23-3/8 x 1-3/4 inches before ordering.
HVAC technicians should power down the air handler or furnace at the disconnect before replacing the filter. Insert the filter with the airflow arrow on the frame pointing toward the blower and away from the return air duct. Ensure the filter seats flush in the track with no bypass gaps around the frame. Filter replacement intervals depend on system runtime, occupant load, and local air quality conditions.
