Product review (2 stars): GE RPWF Compatible?  Maybe, maybe not.  Check for RFID.
I really thought I was outsmarting the man by purchasing this filter at near 1/2 what GE wants for their OEM version.  After all, the headline is "GE RPWF Smartwater Compatible".  Wasn't compatible with my GE Pro model PYE22PSHSS.  Turns out there is an RFID chip under the "BACK" label on the GE OEM that prevents you from fooling the fridge into thinking it's just a regular filter.  After installing this filter, the fridge shut off the water and displayed a "Filter Leak" message.  If you still have the bypass plug, check it for the RFID tag, under the "BACK" sticker.
