Mueller Streamline 274200250 Air Filter 20x25x1

Product Description

The MUELLER STREAMLINE 274200250 is a fiberglass disposable air filter sized at 20 x 25 x 1 inches, designed for use in forced-air HVAC systems. This flat-panel filter captures airborne particles including dust, lint, and larger debris, protecting system components such as blower motors, coils, and heat exchangers from fouling. It is a single-use design, intended to be discarded and replaced on a regular maintenance schedule. HVAC technicians and facility maintenance personnel install this filter as part of routine preventive maintenance on residential and light commercial air handling equipment. At 24 pounds per case, it is a practical bulk stocking option for service fleets.

This fiberglass disposable filter is suited for residential and light commercial forced-air heating and cooling applications. It fits standard 20 x 25 x 1 inch filter slots found in furnaces, air handlers, and return-air grille housings. The filter is appropriate for installations where basic particulate protection is required and high-MERV filtration is not specified. It is commonly used in rental properties, commercial offices, and any application where frequent low-cost filter changes are the preferred maintenance approach.
