FURNACE FILTER BOX

The Furnace Filter Box (FFB) is made to fit under a standard-width furnace and includes a filter slot with a user-friendly door. Boxes are made “filter depth” and will fit the opening underneath any standard furnace. Our design provides a near perfect air seal in all the seams to ensure the greatest efficiency with your filter. The integrated thumb screw closure provides easy access for customers while preventing airflow from entering around the edge.
