Aaf/flanders 10055.011418 Furnace Filter 14x18x1 Merv 4

Product Description

The AAF/FLANDERS 10055.011418 is a flat-panel, spun fiberglass disposable furnace filter rated up to MERV 4. Measuring 14 inches by 18 inches by 1 inch, it fits standard residential filter slots without modification. The filter captures common airborne particles including dust and lint, making it a practical choice for basic air filtration in forced-air heating and cooling systems. Sold in a case of 12 units, it is designed for approximately 30-day service intervals. No metal media retainers are used in the construction, which simplifies disposal at the end of each service cycle.

This filter is suited for residential forced-air furnaces and air handlers where basic filtration is the primary requirement. It is a common choice in rental properties, light commercial spaces, and applications where frequent filter changes are part of a regular maintenance schedule. HVAC technicians and property maintenance personnel typically stock these in bulk to support high-turnover filter programs. The flat-panel design fits into standard 1-inch filter tracks found in most residential gas and electric furnace systems.
