Fits exactly like my Lennox. I have bought this brand before and was just as happy, although it was the same size it was a bit big. Then Lennox noticed it and it fit like a glove. Use them in place of Lennox Merv 16 filters, which are changed once a year. I change 2-3 times a year depending on usage. My fan is clean so I think they work pretty well. I've been using this brand for 4 years. Too bad they didn't provide a 16 Merv in my size.
