Air Flow Products FB03INS000212624 Furnace Filter Box Insulation

Product Description

The AIR FLOW PRODUCTS FB03INS000212624 is a furnace filter box insulation panel designed to line the interior of a filter box housing in a forced-air heating or cooling system. It reduces heat loss, limits condensation on the box walls, and helps maintain system efficiency by keeping conditioned air temperatures stable within the air handler or furnace cabinet. At 21 inches by 26.4 inches by 24 inches, this insulation is sized for a specific filter box application and is typically installed by HVAC technicians during equipment service, filter box replacement, or new construction duct work.

This insulation is intended for use inside a furnace or air handler filter box in residential forced-air HVAC systems. It is commonly installed where the filter box connects to the return-air duct or furnace cabinet. The dimensions of 21 x 26.4 x 24 inches make it a purpose-fit panel rather than a field-cut product, reducing installation time and ensuring consistent coverage of the box interior. No specific compatible model numbers were provided by the manufacturer for this listing.
