Product review (5 stars): It's a water filter and it works just as it should!
UKF8001 model  is what came with my Whirlpool Frig.  The reviews and price was right so I choose this one. It is a little smaller than than the original model I had. It fits and works fine. The water flow might be a little stronger and the taste is fine. I am pretty sensitive to flavors of water and I didn't notice anything off or funny of the flavor. (I travel a lot and first thing that always reminds me I'm away...a glass of water.)
