Pro-source PS19661 Pleated Air Filter 20x20x2 Merv 11

Product Description

The PRO-SOURCE PS19661 is a wire-backed pleated air filter rated MERV 11 with 65% particle capture efficiency. It is designed for forced-air HVAC systems requiring a nominal 20 x 20 x 2 inch filter. The wire backing supports the synthetic media against airflow pressure, maintaining pleat geometry across the service life of the filter. The paperboard frame provides a rigid, snug fit in standard filter tracks. Maximum rated airflow is 1,050 CFM at a maximum face velocity of 500 FPM, with an initial resistance of 0.28 inches water gauge at that rated velocity. Licensed HVAC technicians and building maintenance professionals are the primary installers.

This filter is suited for residential and light commercial forced-air applications including gas furnaces, air handlers, and packaged rooftop units using a 20 x 20 x 2 inch filter slot. The MERV 11 rating makes it appropriate for systems where improved particulate control is needed beyond standard fiberglass media, targeting dust, pollen, mold spores, and fine dust particles. The manufacturer lists compatibility with any unit accepting this nominal filter size. Actual dimensions are 19-1/2 x 19-1/2 x 1-3/4 inches, which is standard for filters sold at the 20 x 20 x 2 nominal size.

Compatibility

Rated for use with any forced-air unit accepting a nominal 20 x 20 x 2 inch filter. Actual dimensions are 19-1/2 x 19-1/2 x 1-3/4 inches. Verify actual filter slot dimensions before ordering.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Power down the air handler or furnace at the disconnect before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow through the system before seating the filter. Filters should be inspected regularly and replaced when final resistance approaches 1.0 inch water gauge or per the system manufacturer's maintenance schedule.
