Best pleated filter
First time buyer of this product, tried other after market pleated filters and so far this one is the best. I start off buy trying to shine a light thru the filter. If no light shines thru there is no need for a pre-filter. Living in Fla you have your A/C running almost all the time. I highly recommend this product. I have a 4 ton Tane heat pump system with the perfect fit filtration attached to the return
