Pro-source Permanent Filters

Overview

The PRO-SOURCE PRO17820251PL is a permanent, washable air filter built for large particle removal in forced-air HVAC systems. The filter measures 20 x 25 x 1 inches and features a steel frame construction that withstands repeated cleaning and reinstallation. It is rated for a maximum airflow velocity of 300 feet per minute (FPM) and handles up to 1,300 CFM, making it suitable for residential and light commercial air handling units. HVAC technicians and facility maintenance professionals install this filter as a long-term alternative to disposable media filters in systems where routine filter replacement is impractical or cost-inefficient. This filter is designed for applications focused on capturing large airborne particles such as dust, lint, and debris. It fits standard 20 x 25 x 1 inch filter slots found in air handlers, furnaces, and fan coil units. The steel frame provides structural rigidity under sustained airflow, and the permanent media can be removed, cleaned, and reinstalled as part of a regular preventive maintenance routine. It is well-suited for light industrial, commercial HVAC, and residential systems where large particle loads are a primary concern.
