Pro-source PRO21543 Pleated Air Filter 16x25x4 Merv 13

Product Description

The PRO-SOURCE PRO21543 is a MERV 13 pleated air filter designed for high-efficiency particulate capture in residential and light commercial HVAC systems. Built with a wire-backed synthetic media and a beverage board frame, it delivers 80 to 85 percent particle capture efficiency across a broad range of airborne contaminants. The nominal size is 16 x 25 x 4 inches, with actual dimensions of 15.5 x 24.5 x 3.75 inches. Rated for airflows up to 1,400 CFM at a maximum velocity of 500 feet per minute, this filter handles the demands of standard forced-air systems. Licensed HVAC technicians and facilities maintenance personnel typically install this filter as part of routine preventive maintenance.

This filter is suited for use with any forced-air unit that accepts a 16 x 25 x 4-inch filter. It performs well in residential air handlers, light commercial rooftop units, and makeup air systems requiring enhanced filtration. With a MERV 13 rating, it captures fine particulates including dust, pollen, mold spores, and certain bacteria-carrying particles. The initial resistance is 0.34 inches water gauge at 500 feet per minute, rising to a final resistance of 1 inch water gauge at end of service life. The integrated beverage board frame provides structural rigidity during handling and installation. This filter also earns LEED points, making it a practical choice for green building projects.

Compatibility

Designed for use with any HVAC unit accepting a nominal 16 x 25 x 4-inch filter slot. No brand- or model-specific compatibility is stated by the manufacturer.

Installation Notes

Always shut down the HVAC system at the thermostat and disconnect power at the air handler before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow into the blower section before fully seating the filter. Inspect the filter slot for frame damage or bypass gaps and seal as needed to maintain rated efficiency. Filter replacement should follow manufacturer service intervals or when final resistance is reached.
