Product review (1 stars): The WD-4396701 Filter doesnt fit my whirlpool refrigerator
I purchased 3 - 4396701  water filters and they didn't fit, I called the eco filter company and was told that it was a was an assembly problem, their engineers stated that it is designed to fit.
I purchased another brand (Aquarius) and it fit
perfectly. Amazon refunded my purchase. I don't recommend buying the waterdrop water filter by eco filter. For a Westinghouse refrigerator.
