Pro-source PRO21142 Pleated Air Filter 18x25x2 Merv 8

Product Description

The PRO-SOURCE PRO21142 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. It uses a synthetic, wireform-free pleated media construction with an integrated beverage board frame. Rated at 1,550 CFM maximum airflow, it handles an initial resistance of 0.18 inches water gauge at 375 FPM and 0.26 inches water gauge at 500 FPM. Nominal size is 18 x 25 x 2 inches, with actual dimensions of 17.5 x 24.5 x 0.875 inches. HVAC technicians and maintenance professionals install this filter as a standard scheduled-replacement component in forced-air systems.

This filter suits any forced-air heating or cooling unit that accepts an 18 x 25 x 2 inch nominal filter. It is rated for use in residential furnaces, air handlers, and central air conditioning systems where MERV 8 filtration is specified. MERV 8 media captures a broad range of airborne particles including dust, pollen, mold spores, and lint, making it appropriate for standard residential indoor air quality maintenance and as a step up from fiberglass panel filters. Maximum operating temperature is 150 degrees F.

Compatibility

Designed for use with any forced-air HVAC unit accepting a nominal 18 x 25 x 2 inch pleated air filter, per manufacturer specification.

Installation Notes

HVAC technicians and qualified maintenance personnel should shut down the air handler or furnace at the equipment disconnect before replacing this filter. Install the filter with the airflow arrow on the frame pointing toward the blower. Verify the filter seats flush in the rack with no gaps at the frame edges, as bypass air around the filter reduces filtration efficiency. Follow local codes and equipment manufacturer guidelines for recommended filter change intervals, typically every 60 to 90 days under normal operating conditions.
