Pro-source PRO11371 Pleated Air Filter 20x20x1 Merv 8

Product Description

The PRO-SOURCE PRO11371 is a pleated air filter rated MERV 8, designed for residential and light commercial forced-air HVAC systems. Constructed with a synthetic filter media and a wire frame, it delivers reliable particulate capture across a broad range of airborne contaminants including dust, pollen, and mold spores. The filter handles up to 1,111 CFM of airflow and is rated for a maximum temperature of 120 degrees F. At its nominal 20 x 20 x 1 inch size, it fits standard filter slots in furnaces and air handlers without modification. Installation is straightforward, making it a practical choice for any licensed HVAC technician or service professional managing routine filter replacements.

This filter is suited for use in residential furnaces, central air handlers, and light commercial HVAC equipment requiring a 20 x 20 x 1 inch nominal filter slot. The MERV 8 rating makes it an appropriate upgrade from fiberglass panel filters in systems where moderate particulate filtration is needed without significantly restricting airflow. The ring panel frame style and wire backing maintain filter shape under normal operating static pressures, supporting consistent performance throughout the service interval.

Installation Notes

Filter replacement is typically performed by an HVAC technician or qualified service professional. Before servicing, shut off system power at the disconnect or thermostat and ensure the blower has stopped completely. Insert the filter with the airflow direction arrow on the frame pointing toward the blower. Inspect the filter housing gasket or seal on each replacement to confirm no bypass gaps are present around the filter edges.
