Product review (5 stars): Works good and is interchangable were you need the RPWF filter
My current new refrigerator requires the RPWF filter but this newer RPWFE filter fits the quick disconnect just fine and it does say on the box it's interchangeable. The only difference I noticed is some kind of sensor on the back side of the filter I assume for other types of refrigerators. Fit in just fine, no leaks and good for another 6 months.
