I purchased a filter from filters fast that was a 25x20x5 just like the one I pulled out. However, the one they sent me said 25x20x5, the measurements were not the same as my original. I called and was told I would have to ship the $25 filter back (it would cost me near that in shipping) for a replacement and I was also told that I had to get the nominal dimensions... poor service. You should be able to buy a 25x20x5 filter and have it fit every time. I wasted $25 and learned my lesson. Stay clear of FF.
