Filter for Atwood furnace

well nothing like burning up you furnace and maybe even your TT. better sleep with one eye open at night. your furnace will overheat so don't even think of it. if the builders wanted a filter they would have put one in. I will bite my tongue for now.

He may have seen the dirt in the AC filter and concluded that an air intake at floor level would be even worse. :S

I am considering putting a lightweight foam or fiberglass filter behind the intake grill on my Atwood 8531 furnace. The opening is 10 x 24". Comments

Why? Millions of these furnaces are in use, the manufacturer never deemed a filter necessary, why would you? :h

It will have to be a very free flowing filter and as you probably know, that type doesn't do much.
Probably worth trying though. If you block it too much the sail switch will keep the furnace from working.
If you try it please come back and let us know how it worked. It's been discussed many times but I don't think I've ever heard of someone actually trying following through.
