Pro-source PRO10446 Pleated Air Filter 18x25x1 Merv 10

Product Description

The PRO-SOURCE PRO10446 is a MERV 10 pleated air filter rated at 55% particle capture efficiency, designed for residential and light commercial HVAC systems. Measuring 18 x 25 x 1 inches nominal (actual dimensions: 17-1/2 x 24-1/2 x 3/4 inches), it uses a wire-backed synthetic media pleated construction supported by a rigid paperboard frame. The wire backing maintains pleat geometry under airflow, helping sustain consistent filtration performance across the filter's service life. Rated for airflow up to 1,175 CFM at a maximum face velocity of 300 feet per minute, this filter suits a wide range of forced-air applications. Licensed HVAC technicians and qualified installers handle replacement as part of routine maintenance.

The PRO10446 is suited for residential forced-air heating and cooling systems, light commercial rooftop units, and air handlers where MERV 10 filtration is specified. At MERV 10, it captures fine dust, lint, pollen, mold spores, and some fine particles, making it a practical step up from standard MERV 7-8 fiberglass or polyester panels. The paperboard frame provides structural integrity in standard 1-inch filter tracks. The manufacturer rates this filter for use with any unit accepting an 18 x 25 x 1-inch nominal filter, covering a broad range of residential and light commercial equipment.

Installation Notes

Power down or set the thermostat to the off position before replacing the filter to prevent debris ingestion during changeout. Install with the airflow arrow on the filter frame pointing toward the blower or air handler. Confirm the filter track accepts a 1-inch nominal depth; actual depth is 3/4 inch. Follow local mechanical codes and equipment manufacturer service intervals for replacement frequency.
