Pro-source PRO19641 Pleated Air Filter 20x20x1 Merv 11

Product Description

The PRO-SOURCE PRO19641 is a wire-backed pleated air filter rated MERV 11, designed to capture fine particulates in residential and light commercial HVAC systems. The synthetic filter media is supported by a wire backing that holds pleat shape under airflow, maintaining consistent performance across the service life of the filter. The beverage board frame provides rigidity for a secure fit in standard filter housings. Airflow capacity is rated at 1,050 CFM, with initial resistance of 0.20 inches w.g. at 300 FPM and 0.28 inches w.g. at 375 FPM. HVAC technicians and facilities maintenance personnel are the primary installers.

This filter is suited for use in forced-air heating and cooling systems where mid-range filtration efficiency is required. MERV 11 captures particles including dust mite debris, mold spores, pet dander, and fine dust, making it appropriate for residential applications with allergy concerns or light commercial environments. The nominal size of 20 x 20 x 1 inches fits a wide range of standard filter slots. The manufacturer designates this filter for use with any unit accepting that nominal size.
