Product review (5 stars): Finally a filter that fits and works correctly!
GREAT FILTER!!!  Finally one that fits!  This is the actual UKF8001AXX filter.  UKF8001 is many times substituted for UKF8001AXX but it will NOT fit!  Look at the top of your filter - if you see a bunch of tiny holes it will NOT work in a fridge that requires the UKF8001AXX filter.  Physically it will fit, but you won't get even a trickle of water.  If you have one or two oblong holes, each about half a centimeter, this is the filter for you!
