Product review (5 stars): Almost perfect....almost
My previous filters had no metal frame. This one came with metal around it with perforations. I thought the perforations would work fine but like another reviewer, I found water all over my floor around the furnace. After removing the metal frame and putting the un-framed filter back in, it works great. This is very hard to find and I'd buy another. Hope this helps - cross references these filters (as far as I know): EP036, 10HF, H7504, RH7504, FH-182.
