Product review (5 stars): I bought these a few weeks ago as a replacement ...
I bought these a few weeks ago as a replacement for my RPWFE filters. Yes, they aren't supposed to replace the RPWFE, but if you buy the RPWFE filters from GE, they're right at $50 each and--from a filtration perspective--do nothing more for you. The only thing you get with the E filter is the six month timer that displays on the little monitor on the refrigerator door. Handy, sure, but in no way worth paying 4x as much as these filters. So these filters on their own won't work in replacement of the E filters, but all you have to do is peel the RFID tag off the original E filter and stick it on one of these and you're off and running.
