Fantastic!

Got exactly what I ordered,(an odd ball size for my HVAC unit). The FilterKing filters fit much better that the closest commonly available size. Thank you guys for making it so easy to find custom filter sizes.

Custom Filter

I couldn't find a proper size HVAC filter over the counter and other on-line quotes for my filter were through the roof. Filter King, however, came through and I received my custom sized filters on time, and they fit perfectly.
