Aaf/flanders 10055.01152 Furnace Filter 15x20x1 Merv 4

Product Description

The AAF/FLANDERS 10055.01152 is a flat-panel spun fiberglass disposable furnace filter sized 15 x 20 x 1 inches and rated up to MERV 4. Designed for residential forced-air systems, it captures airborne dust and lint before they reach the heat exchanger or blower. The simple flat-panel construction contains no metal media retainers, making disposal straightforward and reducing the risk of loose hardware during changeout. Rated as a 30-day filter, it is intended for frequent replacement cycles where low static pressure drop and basic particulate protection are the priority. HVAC technicians and facility maintenance staff commonly stock this filter in bulk, and this SKU ships as a 12-unit pack.

This filter is suited for residential gas furnaces, heat pumps with air handlers, and light-commercial forced-air systems where baseline filtration is acceptable. It is a common fit in return-air grilles and filter racks that accept a 1-inch flat-panel filter. The 30-day replacement interval makes it a standard choice for high-dust environments such as construction sites, rental properties, or systems running continuous fan operation. Its low resistance to airflow supports older or lower-static blower assemblies that cannot handle high-MERV media.

Key Features

• Spun fiberglass flat-panel construction with no metal media retainers for easy, safe disposal
• MERV 4 rating captures dust, lint, and large airborne particles
• Sized 15 x 20 x 1 inches for standard filter racks and return-air grilles
• 30-day replacement interval suits high-turnover maintenance programs
• Sold as a 12-pack, reducing per-unit cost for bulk stocking
• Low static pressure drop supports older blower assemblies and continuous-fan applications

Compatibility

Designed as an OEM-style replacement flat-panel furnace filter for residential and light-commercial forced-air systems that accept a 1-inch filter measuring 15 x 20 x 1 inches.

Installation Notes

Turn off the furnace or air handler at the thermostat and disconnect power at the disconnect switch or breaker before servicing the filter. Note the airflow direction arrow printed on the filter frame and orient it so airflow moves from the return-air side toward the blower. Dispose of the used filter immediately in a sealed bag to contain captured particulate. Replace on a 30-day cycle or more frequently in high-dust environments.
