Pro-source PS10872 Panel Air Filter 20x20x1 Merv 9

Product Description

The PRO-SOURCE PS10872 is a MERV 9 panel air filter rated at 35% particle capture efficiency, designed for use in residential and light commercial HVAC air handling systems. Built with a lofted synthetic polyester fiber media and a galvanized steel frame, this filter handles airflows up to 833 CFM at a maximum velocity of 300 feet per minute. The nominal size is 20 x 20 x 1 inches with actual dimensions of 19.5 x 19.5 x 0.75 inches. Initial resistance is 0.29 inches water gauge at 300 FPM, with a final resistance of 1.0 inch water gauge. HVAC technicians and service professionals install this filter as part of routine maintenance or system changeout.

This filter is suited for standard residential forced-air furnaces, air handlers, and packaged HVAC units using a 20 x 20 x 1 filter slot. The MERV 9 rating makes it appropriate for applications that require filtration beyond basic dust capture, including environments with moderate particulate loads. The galvanized steel frame provides structural integrity under sustained airflow conditions. Rated for use in systems operating up to 150 degrees F, this filter covers a wide range of residential and light commercial air handling applications.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handling unit or furnace before removing the existing filter and inserting the replacement. Confirm airflow direction markings on the filter frame align with the direction of airflow in the system. Replace filters on a schedule appropriate to the site conditions and system runtime to avoid excessive pressure drop across the filter.
