Product Description

The AIR FLOW PRODUCTS FB03INS000142624 is a furnace filter box insert designed to fit within a filter box housing in a forced-air heating and cooling system. This insert provides the structural support and sealing surface needed to hold a filter element securely in the airstream, reducing bypass and maintaining filtration efficiency. Measuring 14.1875 inches wide by 26.4375 inches tall by 24 inches deep, it is sized for a specific filter box configuration found in residential and light commercial HVAC applications.

It is used in systems where the filter box assembly requires a dedicated insert to properly retain the filter media and maintain consistent airflow through the air handler or furnace. Proper sizing is critical, and this unit is built to the specific dimensions noted above to match its intended housing.
