Mann+hummel 21208-021020 Pleated Air Filter Merv 8A

Product Description

The MANN+HUMMEL 21208-021020 is a MERV 8A pleated air filter designed for use in residential and light commercial forced-air HVAC systems. It captures a broad range of airborne particulates including dust, pollen, mold spores, and pet dander, making it a reliable choice for standard filtration applications. With nominal dimensions of 10 x 20 x 2 inches and actual dimensions of 9.5 x 19.5 x 1.75 inches, this filter fits standard 2-inch filter slots without modification. HVAC technicians and service pros stock this filter as a routine maintenance replacement for return-air grilles and air handler filter racks.

This filter is suited for residential split systems, packaged units, and light commercial air handlers that accept a standard 10 x 20 x 2 nominal filter. It is a common replacement in regular preventive maintenance programs, typically scheduled on 60- to 90-day intervals depending on occupancy, pet presence, and local air quality. The pleated media construction provides greater surface area than fiberglass panel filters, supporting lower pressure drop and longer service intervals.
