My mother had a washable filter which was no good. We could not find the filter measurements at local stores. I checked this website which offers customs measurements. My order was processed quickly and it was a perfect fit. I will be ordering from here from now on for my mom.

This Filterbuy 20x21x1 is actually 20x21, not 1/2 smaller each direction, which is the size needed for my Trane air handler.

Custom filter was made perfectly to spec.

It is very odd that our new furnace required a custom filter size (15 1/2 x 24) but that it does. The previous owner tried to cram in a 16 x 25 but it was a disaster. Anyway, Filterbuy made us one to spec and it was perfect. Delivery was fast too. Thanks, guys!

Perfect fit. After struggling, for years, with filters that were 1 too big I ordered a pair of custom made filters. I installed one today and it fits perfectly.
