Wrong size

Two orders in a row now Filterbuy has screwed up the size on a custom order. The stickers on them are the right size, but when measured they are significantly larger. Same mistake both times. As a result they do not fit. This used to be a good company. They've lost their way the last 2 yrs. Try somewhere else.

I love these filters. I have really bad allergies, 5 dogs and a cat. What a combo, but these filters really do help with air quality. Plus they are delivered right to my door.

The furnace filter I bought is the same size that I replaced, and it is much narrower than the same sized one that I replaced in my furnace

I have been using your filters for a few years now. I like that they remove a lot of the unwanted dirt and pollutants in the air. And the price isn't bad either.
