Aaf/flanders 10055.01203 Furnace Filter 20x30x1 Merv 4

Product Description

The AAF/FLANDERS 10055.01203 is a flat-panel spun fiberglass disposable furnace filter measuring 20 x 30 x 1 inches with a MERV 4 efficiency rating. Sold in a case of 12 units, it is designed for standard residential forced-air furnace and air handler applications where basic filtration of large airborne particles is required. The flat-panel, no-metal-media-retainer construction keeps the filter lightweight and easy to handle. At a recommended service interval of 30 days, it is well suited to high-replacement-rate maintenance programs. HVAC technicians and property maintenance professionals commonly stock these in bulk for scheduled filter change routes.

This filter is used in residential gas furnaces, electric furnaces, and air handlers that accept a 20 x 30 x 1 inch nominal filter. Its primary function is capturing dust and lint before they reach the blower and heat exchanger. The 30-day replacement cycle makes it a standard choice for rental properties, light commercial spaces, and accounts where frequent, low-cost filter changes are the preferred maintenance strategy. The spun fiberglass flat-panel design offers low static pressure drop across the filter media.
