Type of extra filter needed with Electronic air cleaner?
I have a 3 ton heat pump with an electronic air cleaner. Before the return air enters the electronic air cleaner there is a 1/4" aluminum mesh screen, and after the air cleaner I have been using the 1" pleated style MERV 8 filter. To maximize air flow I am considering replacing the pleated style filter with a cheap fibreglass filter with no MERV rating; my thinking being that an electronic air cleaner plus a 1" pleated MERV 8 is overkill. Mostly I want to maximize air flow, but I also don't want to develop a dirty coil. What do you guys think? Great forum by the way, long time lurker, first time poster!
