Product review (4 stars): RPWFE replacement just fine
First off I used this for a RPWFE, chip filter.  I simply took the chip off of the old filter and taped it on this filter.  It works fine BUT the display says replace as -- days overdue. I have amazon sending one every 6 months so I know when to replace it.  There is NO DIFFERENCE other than the chip--GE's way of sticking it to you after the sale of a $3,000.00 fridge.

When I put it in no leaks inside. The initial output is gray water for about a gallon then it cleans up nicely. Also initially it dripped from door output after water was released but that stopped after the flush.  I did flush with about 2 gallons as instructions say.  Quite frankly I was just going to use  the bypass filter after the GE expired but for $12.00 every 6 months I'll be a sucker and "filter" my already clean water.
