Default Looking for Filter Material Ideas for Air Cleaner

I would like to pick some member’s brains as to what they use for air cleaner filter material? I want to run velocity stacks I already have. At the top of the bell of each stack are 2 perforated screens to sandwich foam between. I could buy a furnace filter and cut to size. I don’t know if the foam is readily available? Any members have this dilemma and their advice?

I'd try to find something that wasn't flammable. I caught my carburetor on fire about a dozen times Thrusday. If I had a foam filter on it I might not have a car now.

Do boats have air cleaners or just a flame arrester? pretty sure everything in boats I think has to be non flammable.

I've seen boats with a woven stainless steel type filter, or flame arrestor. I don't know how well they filter, or how much air they will flow. I've seen velocity stacks with small round paper filters on top.

Not versed in boat setups, but I don’t think boats will provide much useful info except what Scott pointed out. That being, the flammability of a filter material, which is a good point.

I do not want anything sitting on top of the stack. Must be concealed below the top of the stack. Thanks.

Do you know if that foam fire resistant? I had the same flat-top velocity stacks on my car and swapped them out for the velocity stacks with the air cleaners on top as the fear of fire got the best of me, but I'd like to put the old flat ones back on it sometime if I can find something that is flame/fire resistant.

I like that. Red would look...well, red! Pretty cool. I am wondering if a flameproof coating or flame retardant spray is available? And how would that effect the filtration?

Why not test the filter buy doing a burn test before trying frame retardants.
