Product review (1 stars): It's nice that still works well and I've never had a ...
It doesn't fit my refrigerator even though it shows compatibility with my model (ED2PHEXNQ00).  In another review someone mentioned the same problem.  Whirlpool customer service indicated this filter may not work on older refrigerators, although they do not specify how old.  Mine was manufactured in 2004.  It's nice that still works well and I've never had a problem with it, but I'm retuning mine because it simply won't go in.  It's not easy to replace.  You need a pair of pliers to turn the handle and it's easy to break.  I broke my handle trying to get this new style filer in place.  The neck on the new one is different as you can see from my photo.  According to Whirlpool I'm SOL - unless I can find a supplier who still has the old style units.
