Product review (1 stars): It doesn't fit!
Much like the other new EveryDrop water filters (see reviews on size 5), the new filter does not fit my fridge, never mind how much whirlpool insists it does. Apparently there are multiple manufacturers, and whirlpool cannot guarantee whether the new version or old version will ship. In older refrigerators, only the old version will work. but, it's hard to get a version that does work, and there's no guarantee you'll get one, regardless of where you buy it from. I'm very frustrated with whirlpool on this matter.
