Furnaces that take a 12.25 x 25 filter

13 furnace models in our list take a 12.25 x 25 filter.

Pick the thickness that matches your old filter:

12.25 x 25 x 1 12.25 x 25 x 2 12.25 x 25 x 4 12.25 x 25 x 5

The maker lists width and height only. Most filter racks next to a furnace hold a 1-inch filter; a separate filter cabinet usually holds a 4- or 5-inch one. Check the thickness printed on the edge of your old filter before you order.
