Pro-source PRO21526 Merv 13 Pleated Air Filter 20x25x2

Product Description

The PRO-SOURCE PRO21526 is a MERV 13 pleated air filter designed for forced-air HVAC systems in residential and light commercial applications. It measures 20 x 25 x 2 inches nominal (actual dimensions: 19.5 x 24.5 x 1.75 inches) and delivers 80 to 85 percent particle capture efficiency. The wire-backed pleated synthetic media holds its shape under airflow and resists collapse at higher velocities. The beverage board frame provides structural rigidity while remaining easy to handle and dispose of. Licensed HVAC technicians and facilities maintenance personnel are the typical installers.

This filter fits any forced-air air handler or furnace that accepts a 20 x 25 x 2 inch filter. It is rated for airflows up to 1,300 CFM at a maximum face velocity of 500 FPM, making it suitable for residential split systems, packaged units, and light commercial air handlers. Initial resistance is 0.25 inches water gauge at 375 FPM and 0.39 inches water gauge at 500 FPM, with a final resistance of 1.0 inch water gauge. Its MERV 13 rating supports improved indoor air quality in environments where fine particulate control matters.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Always power down the air handler or furnace before removing the old filter and installing the new one. Verify airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Check the system manufacturer's recommended filter change intervals and inspect the filter housing for air bypass gaps that would reduce filtration effectiveness.
