Pro-source PRO21590 Pleated Air Filter 20x25x1 Merv 13

Product Description

The PRO-SOURCE PRO21590 is a MERV 13 pleated air filter designed for residential and light commercial HVAC applications where improved particulate capture is required. The filter uses a wire-backed synthetic media construction that holds pleat geometry under airflow, maintaining consistent face velocity and reducing pressure drop irregularities over the service life. Rated at 80 to 85 percent particle capture efficiency per ASHRAE 52.2, it targets fine dust, pollen, mold spores, and fine particulates. Nominal size is 20 x 25 x 1 inches with an actual size of 19.5 x 24.5 x 0.75 inches. Licensed HVAC technicians and facilities maintenance professionals are the primary installers.

This filter fits standard 20 x 25 x 1 inch filter slots in forced-air furnaces, air handlers, and packaged HVAC units. The beverage board frame provides rigidity for single-use installation in any unit accepting this nominal size. Maximum rated airflow is 1,050 CFM at a maximum face velocity of 300 feet per minute, making it suitable for residential systems and smaller commercial air handlers operating within those parameters. The filter is also noted to earn LEED points, which may be relevant for commercial building compliance documentation.

Installation Notes

Installation should be performed by a qualified HVAC technician or trained maintenance professional. Power down the air handler or furnace at the disconnect before removing the existing filter and inserting the replacement. Verify airflow direction arrows on the frame align with the system airflow direction before securing the filter in the rack. Dispose of the used filter per local waste handling requirements.
