The other system only takes a 2" at the air handler - my husband gets those locally and I am not sure what he buys, but he does get the pleated type. In addition, every return duct has a 12"x12"x1" filter so the air returning to the air handlers is filtered.

They are pretty effective - Friday we had a stump grinding machine working outside. It badly needed servicing and was burning a lot of oil. We got a little smell into the house as he was working upwind from the area where our fresh air intake is, but that was it and the smell went away rapidly.
