I had the same problem as other reviewers. This does not replace the old whirlpool filter #4396508 as advertised.. Had to return filter.. I cannot find a filter made by whirlpool that will fit in my whirlpool fridge now. It does not make sense. I will have to use a generic filter after I already tried a generic that did not filter well. I suppose I will have to keep looking....
