Product Description

The AAF/FLANDERS 10055.012036 is a spun fiberglass flat panel furnace filter measuring 20 inches by 36 inches by 1 inch. Sold in a 12-pack, it carries a MERV 4 rating and is designed for 30-day service intervals in residential forced-air heating and cooling systems. The EZ Flow II construction uses a disposable spun fiberglass media that captures common airborne particles such as dust and lint. Its flat panel design fits standard filter tracks without modification. HVAC technicians and property managers commonly stock these in bulk for routine filter change programs.

This filter is suited for residential gas furnaces, heat pumps, and air handlers where basic particulate filtration is required. At MERV 4, it provides entry-level filtration appropriate for systems that prioritize high airflow with minimal static pressure drop. The 30-day recommended replacement cycle makes it well suited to high-use environments or rental properties on scheduled maintenance programs. Pack quantity of 12 units supports multi-unit or multi-system service routes.
