Pro-source PRO10426 Pleated Air Filter 20x30x1 Merv 8

Product Description

The PRO-SOURCE PRO10426 is a MERV 8 pleated air filter rated for residential and light commercial HVAC applications. It features a wire-backed synthetic media construction with a paperboard frame, giving the filter structural rigidity while maintaining airflow efficiency. The nominal size is 20 x 30 x 1 inches, with actual dimensions of 19.5 x 29.5 x 0.75 inches. At a maximum face velocity of 300 feet per minute, the filter delivers 1,250 CFM of airflow with an initial resistance of 0.14 inches water gauge. It achieves 35 percent particle capture efficiency, targeting common airborne particulates in forced-air systems. Licensed HVAC technicians and qualified installers use this filter as a standard replacement in ducted air handler and furnace applications.

This filter is suited for use in residential split systems, packaged units, and light commercial air handlers where a nominal 20 x 30 x 1 inch filter slot is specified. It is rated for operating temperatures up to 200 degrees F, making it compatible with both heating and cooling cycles. The wire-backed pleated design maintains media shape under normal system static pressure, preventing collapse during operation. Because the supplier data specifies compatibility with any unit accepting this nominal size, it functions as a broad-fit replacement across most ducted forced-air systems.

Compatibility

Designed for use with any forced-air HVAC unit accepting a nominal 20 x 30 x 1 inch filter. Actual dimensions are 19.5 x 29.5 x 0.75 inches — confirm filter rack clearance before installation.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service personnel. Power down or set the system to off at the thermostat before removing the existing filter to prevent unfiltered air from bypassing the rack during the swap. Insert the filter with the airflow arrow on the frame pointing toward the blower or air handler. Inspect the filter rack for damaged tracks or gaps that could allow air bypass, and follow local mechanical codes for recommended filter change intervals.
