Pro-source Extended Surface Mini-pleat Rigid Filters

Overview

The PRO-SOURCE PRO21613 is a MERV 13 mini-pleat pleated air filter designed for forced-air HVAC systems requiring high-efficiency particulate filtration in a 4-inch depth slot. Built with a synthetic media and an integrated plastic frame, this filter captures fine dust, pollen, mold spores, and fine particles in the PM2.5 range. Nominal dimensions are 12 x 24 x 4 inches, with actual dimensions of 11.38 x 23.38 x 3.75 inches. Rated airflow is 1,250 CFM at a maximum face velocity of 625 FPM. HVAC technicians and mechanical contractors install this filter in air handlers, furnaces, and commercial rooftop units where MERV 13 filtration is specified. This filter fits standard 12 x 24 x 4 inch filter housings found in residential and light commercial forced-air systems. The mini-pleat construction increases media surface area relative to standard pleated filters, which helps maintain lower pressure drop across the service interval. Initial resistance is rated at 0.22 inches w.g. at 375 FPM, 0.34 inches w.g. at 500 FPM, and 0.48 inches w.g. at 625 FPM, with a final resistance of 1.5 inches w.g. It is suited for applications where indoor air quality standards or building codes call for MERV 13 or higher filtration, including schools, medical offices, and multi-family residential systems.
