Pro-source PRO10398 Pleated Air Filter 20x24x4 Merv 8

Product Description

The PRO-SOURCE PRO10398 is a MERV 8, wire-backed pleated air filter designed for residential and light commercial HVAC systems. Measuring 20 x 24 x 4 inches nominal, it delivers 35% particle capture efficiency and handles airflow up to 1,650 CFM at a maximum face velocity of 500 feet per minute. The synthetic filter media is supported by a wire backing that holds pleat geometry under sustained airflow, reducing media collapse and maintaining consistent resistance. An integrated paperboard frame ensures dimensional stability during installation. Rated for temperatures up to 200 degrees F, this filter meets ASHRAE 52.2-2012 and UL 900 standards. HVAC technicians and service contractors install this filter in standard 4-inch filter housings.

The PRO10398 is suited for residential forced-air furnaces, air handlers, and packaged units that accept a 4-inch deep filter. The 20 x 24 x 4 nominal size fits a wide range of standard filter slots. With an initial resistance of 0.14 inches water gauge at 500 FPM and a final resistance of 1.0 inch water gauge, it is appropriate for systems with typical residential or light commercial fan capacity. The filter is sold individually and is rated for use with any unit, making it a practical stocking choice for service fleets that cover multiple equipment brands and models.

Installation Notes

Installation is performed by HVAC technicians or qualified service 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 toward the blower. Inspect the filter track and housing seal for gaps that could allow unfiltered bypass.
