Oh ok, so that makes life even easier then worrying about a filter system, if I even go with one.
I was considering my fish tank filters so I can just slide them in and
out of a slot in front of my 4" exhaust port. I can easily remove the
carbon and use that in other fish tank filters I have running.
Filter similar to these at
ThatFishPlace.com (I get them cheaper) -
Or maybe I can use one of our old furnace filters or A/C filters... oh wait...
How about one of those metal type grease filters for those stove venting hoods?
They can be washed out when they get dirty and clogged up. I spray
mostly enamel so I could soak it in cheap paint thinner and then take
it out side and blast air through it from my garage compressor. Humm...
