I live in a Mobile Home as another question stated. I also have an Coleman Evcon Furnace with NO visible Model number and I'm looking to replace my filter. The old owner Cut to fit the their filter which doesn't fit that well! My measurements where odd compaired to other filters Ive had B4; they were 17 1/2 H x 19 1/4 W x 1 D. Now I don't want to have to get "Custom" Filters, I would think Coleman would have an OEM filter for them, However, I can't find one for the life of me! Any suggestions I REALLY need NEW ones these are disgusting, I'm living in Triple digit heat and my house isn't cooling! :( Please Help. Lisa

I`ve dealed with very few coleman furnaces but found the homeowners had bought to filters of whatever the size that was needed to cover the area where 1 bigger filter should go
example 2 10x9`s fitted end to end
