Filter for Atwood furnace
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

Wow, to all that worry about burning up the furnace with a filter, do you really think the intake is that well sealed?? I have a paper filter behind the grill, but it draws from cabinets under the sink also!
A, it won't burn up, it will cycle on the limit switch, shortening the lifespan.
B, if it's not drawing through the filter, why have it?
