IMPORTANT NOTE: Almost ALL furnace filters have a different “actual size” than the nominal size printed on the air conditioner filter. It’s best if you measure your air filter for the EXACT size and compare it to our “Actual Size” – and then you can be sure your A/C air filter fits! Make sure you click the View All Sizes link at the bottom of each of the size menus. We may already have the size you need.   

CONSTRUCTION: Custom air filters are made by cutting down or combining 1, 2 or 3 A/C air filter frames. Depending on the size we may use tape to make your custom size air filters. So, they might not be pretty, but they WILL be strong.

RETURNS: Custom AC furnace air filters are not returnable since we hand make them per your exact dimensions when you enter your air filter size above. Since you can NOT return custom sized air filters, please make sure you order the EXACT size you need to the fraction of an inch.
