Question: Dose it say 18 x 20 on filter??
Document: What the description said exact fit. Nor much more to say about product. I can't think of anything else to say
This was just what I needed. This in a name brand filter, that was delivered fast. I would order this again in a heartbeat. It was just perfect.
I can't find this air filter at my local store, so I was happy that I could find it on amazon. I am sure if I dug around, I would found a little better price, but the filter I found was priced competitively and the shipping was free.
just got new heat pump with air box with this  in it. dust is stop dead at the return at the air handler
This is a whole lot cheaper than buying the paper refill, disassembling, breaking the ^%&*&*! clips  and ten times easier. perfect fit.
Love it! Lasts a year! Much easier than having to change out monthly! Really makes it much simpler! Thank you !
