Hart Cooley 274120200 Fiberglass Air Filter 12x20x1

Product Description

The HART COOLEY 274120200 is a 12x20x1 fiberglass disposable air filter designed for residential and light commercial HVAC systems. It captures airborne particles such as dust, lint, and debris, protecting blower components and heat exchangers from contamination. The fiberglass media construction provides low-restriction airflow, making it well suited for systems that require minimal static pressure drop. This filter is sold as a single unit and is installed and replaced by HVAC technicians or knowledgeable facility maintenance personnel during routine service intervals.

This filter fits standard 12x20x1 filter slots found in forced-air furnaces, air handlers, and return air grilles in residential and light commercial applications. Its disposable design allows for straightforward changeout without cleaning or reconditioning. The nominal 12x20x1 size is among the most common filter dimensions in residential HVAC, making this a frequently stocked replacement for routine maintenance programs.
