The PRO-SOURCE PRO21580 is a MERV 13 pleated air filter designed for residential and light commercial HVAC systems requiring high-efficiency particulate capture. The filter uses a wire-backed synthetic media construction that maintains pleat geometry under airflow, delivering 80 to 85 percent particle capture efficiency across the rated velocity range. It is rated for a maximum airflow velocity of 300 feet per minute (FPM) and a volumetric flow of 650 CFM. A beverage board frame provides structural rigidity and a consistent seal in standard filter housings. Licensed HVAC technicians and building maintenance personnel are the typical installers.
This filter fits any forced-air unit accepting a 16 x 20 x 1 inch nominal filter, including residential furnaces, air handlers, and packaged rooftop units. Nominal dimensions are 16 x 20 x 1 inches; actual dimensions are 15.5 x 19.5 x 0.75 inches. The wire-backed pleated design supports sustained airflow performance in high-demand applications. This filter also earns LEED points under applicable green building rating criteria, making it a suitable specification for projects with indoor air quality documentation requirements.
Designed for use with any forced-air HVAC unit accepting a nominal 16 x 20 x 1 inch pleated filter.
Installation should be performed by a qualified HVAC technician or trained maintenance professional. Power down the air handling unit at the disconnect or thermostat before removing and replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the system airflow direction before seating the filter. Inspect the filter housing for bypass gaps and ensure the beverage board frame seats flush on all four sides to prevent unfiltered air from passing the media.
