Aaf/flanders 10055.012024 Furnace Filter 20x24x1 Merv 4

Product Description

The AAF/FLANDERS 10055.012024 is a flat-panel spun fiberglass disposable furnace filter rated up to MERV 4. Measuring 20 inches by 24 inches by 1 inch, it fits standard residential forced-air furnace filter slots. The EZ Flow II design uses a fiberglass media mat with no metal media retainers, keeping the filter lightweight and easy to handle. At MERV 4, it captures large airborne particles including dust and lint, providing baseline protection for the blower and heat exchanger. This filter is rated for approximately 30 days of service before replacement. It ships in a pack of 12, making it a practical stock item for technicians servicing multiple residential units.

This filter is suited for residential forced-air heating and cooling systems where basic filtration and low static pressure drop are the priorities. The flat-panel form factor and 1-inch depth fit the most common filter-return configurations found in residential gas furnaces and air handlers. The 30-day service interval is appropriate for average household environments; dustier or high-traffic installations may require more frequent changes. HVAC technicians often stock the 12-unit case to supply customers on routine maintenance visits.
