Pro-source PRO19666 Pleated Air Filter 12x24x4 Merv 11

Product Description

The PRO-SOURCE PRO19666 is a wire-backed pleated air filter rated MERV 11, designed for residential and light commercial HVAC systems that require effective mid-range particle filtration. The synthetic pleated media captures dust, pollen, mold spores, pet dander, and fine particulate that lower-rated filters pass through. The beverage board frame provides structural integrity under sustained airflow. At a nominal size of 12 x 24 x 4 inches and rated for up to 1,250 CFM, this filter suits air handlers and furnaces with standard 4-inch filter tracks. It is installed by HVAC technicians and qualified facility maintenance personnel during routine filter service.

This filter fits any forced-air HVAC unit with a 12 x 24 x 4 inch nominal filter slot. The 4-inch depth and high-capacity pleat design extend service intervals compared to 1-inch and 2-inch alternatives, making it a practical choice for residential forced-air systems, light commercial air handlers, and applications where maintaining air quality between service visits is a priority. The MERV 11 rating targets environments with moderate to elevated particulate loads, including homes with pets or occupants with respiratory sensitivities.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified maintenance personnel. Power down the air handler or furnace at the disconnect or breaker before opening the filter access panel. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Dispose of the used filter according to local waste handling requirements and inspect the filter housing for bypasses or gasket damage before inserting the replacement.
