The PRO-SOURCE PRO21261 is a MERV 8 pleated air filter designed for residential and light commercial HVAC applications. It measures 16 x 20 x 2 inches nominal, with actual dimensions of 15-1/2 x 19-1/2 x 1-3/4 inches. The filter uses a synthetic pleated media housed in a paperboard frame with an integrated construction. Rated for up to 1,100 CFM airflow at a maximum velocity of 500 FPM, it carries an initial resistance of 0.23 inches water gauge at 500 FPM. HVAC technicians and service professionals install this filter as a routine maintenance replacement in forced-air systems.
The PRO21261 is suited for any forced-air unit requiring a 16 x 20 x 2 inch filter slot. Its MERV 8 rating provides 35 percent particle capture efficiency, making it appropriate for standard residential filtration where capturing dust, pollen, and larger airborne particles is the primary goal. It performs within a maximum operating temperature of 150 degrees F, covering typical residential and light commercial air handler and furnace applications. This filter meets ASHRAE 52.2-2012 and UL 900 standards.
Designed for use with any forced-air HVAC unit requiring a 16 x 20 x 2 inch nominal filter size.
Installation is performed by HVAC technicians or qualified service personnel as part of routine filter maintenance. Power down or shut off the air handler before removing the old filter and inserting the replacement. Confirm airflow direction arrows on the filter frame align with system airflow before securing the access panel. Dispose of the used filter per local waste handling guidelines.
