Pro-source PRO32035 Pleated Air Filter 18x20x2 Merv 8

Product Description

The PRO-SOURCE PRO32035 is a wire-backed pleated air filter rated MERV 8 with 35% particle capture efficiency. It uses a synthetic filter media supported by a wire backing to hold pleat shape under airflow, housed in a paperboard frame. Nominal size is 18 x 20 x 2 inches with actual dimensions of 17.5 x 19.5 x 1.75 inches. The filter handles up to 1,250 CFM at a maximum face velocity of 500 feet per minute (FPM) and carries an initial resistance of 0.20 inches water gauge at rated velocity. Licensed HVAC technicians and building maintenance professionals install this filter as a standard replacement in air handling units, furnaces, and fan coil systems.

This filter is suited for residential and light commercial HVAC applications where MERV 8 filtration meets the design specification. The 18 x 20 x 2-inch nominal size fits a wide range of return-air grilles, filter cabinets, and equipment filter tracks. The wire-backed pleat construction maintains media integrity across the full rated airflow range, making it appropriate for systems with higher static-pressure requirements than standard non-supported pleated media. It is rated for continuous operation up to 200 degrees F, compatible with any unit accepting this nominal filter size.

Compatibility

Designed as a replacement pleated filter for any residential or commercial HVAC unit, air handler, furnace, or fan coil system accepting an 18 x 20 x 2-inch nominal filter.

Installation Notes

Power down or set the thermostat to off before replacing the filter to prevent unfiltered air bypass and protect the blower. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow in the unit before seating the filter. Inspect the filter track and frame seal on installation to eliminate bypass gaps. Disposal of used filters should follow local waste handling practices; MERV 8 media captures fine particulates that may require bagging before disposal.
