Where is my filter located?
Your filter can be located anywhere between the furnace and the where warm or cool air enters the room. Common locations include inside the ductwork, behind vents or in the air handler itself.
What size filter do I need?
Most furnace filters have two sets of dimensions; nominal and actual. If you measure your filter and it's actually 15 1/2" x 24 3/4" x 3/4", you would round up and search based on the nominal dimensions of 16" x 25" x 1". If the nominal size isn't printed on your old filter just measure your filter width, length and thickness. Round up and you'll get the nominal size. We always recommend measuring your filter just to be sure.
Custom size filters
When ordering custom filters submit the exact size down to 1/8" you would like us to make your filters. Please don't submit the nominal size (rounded size) of the filter, submit the actual exact size.
We love subscriptions, it's something we have offered for a long time.
But lets be real, if you're all about saving money a case is the way to go. Some of the sites out there offer the same filters we sell here via subscription for $15 per filter, for one filter! If you were to buy 4 filters you could have a full case of 12 from us for the same price.
