Product review (1 stars): NOT Compatible with Whirlpool ED2GHEXNQ Side-by-Side Fridge
The OnePurify Water Filter Cartridge (RFC 0500A) was supposed to be a compatible replacement for Filter #4396508, but it was not.  The design of the tip is slightly different shape and DID NOT screw into the slot in my fridge.  Therefore, this filter does NOT work in Whirlpool model ED2GHEXNQ side-by-side refrigerator.
