Product review (4 stars): Very Good Filter replacement for my RPWFE (yes E)
This says it is NOT for the 'E' (RPWF E) however, with a simple 'Work Around', it can be used in a GE Profile Series refrigerator.  GE uses the 'E' series water filter with a simple RFID tag as a SHAMEFUL marketing/sales 'Gimmick' to justify TRIPPING the price of a good water filter.
What benefit does the RFID tag provide for the additional $20 to $30?
-Does it help the filter measure percent of filter contamination?  NO, IT DOES NOT!
-Perhaps it measures the pressure drop as the filter becomes more clogged, alerting the owner to the problem.  NO, IT DOES NOT!
-Does it show a potential failure of the filter media, alerting the owner?  NO, IT DOES NOT!
-How about leak detection, preventing water damage to the refrigerator?  IT DOES NOT!
Then WHY is the RFID tag on the back of each filter....?????
FOUR reasons:  1-Run a SIMPLE countdown timer (worth about 50 cents),  2-Turns on the "OVERDUE" light, REGARDLESS of the level of TRUE contamination of the filter.  3-Uses filter 'Serial number' identification to STOP the CUSTOMER from simply removing the RFID tag from the back of an old filter using the tag for a 'Non-RFID' tagged filter and PREVENTS the CUSTOMER from saving money!  4-MAIN REASON get the customer to PAY M-U-C-H more for each filter than it is worth and buy filters ONLY from GE!!!!  NO competition, a MONOPOLY!
----Imagine if the car companies did that!  You could ONLY buy tires from your local dealer for your make and model of car!

Here is how I now use THIS water filter (and others) in my GE Profile Series refrigerator.
1-Locate the 'Blank' filter by-pass plastic piece sent with your GE Profile Series refrigerator (found this from another reviewer noting there was an RFDI tag on the back of the by-pass).
2-Locate the label "BACK  This side must face inward" and peel it off.  (see the picture)
3-Remove the RFID tag under the label.
4-Open the water filter housing cover inside the refrigerator.
5-Place the RFID tag over the 'FCC'  label on the back inside the filter housing near the screw, hold in place by re-using the label you peeled off  the 'Blank' filter by-pass.  (see picture)
NOW you can install ANY water filter compatible with GE RPWF  (NOT 'E'), saving from $20 to $30+ each!!
--NOTE: 1-This fix will turn OFF the countdown feature but WILL leave ON the Oz. fill and 'Auto-Fill' features.  2-The front panel will now show "NOT FILTERING"  when you fill a container with water or ice (even though you installed a new filter).  This additional insult to the CUSTOMER can be simply overridden by: A) Removing the two screws (inside the upper opening of the dispenser in the door) holding the display on the door.  B) Removing the circuit board connectors  C) Removing the Torx screws holding the circuit board to the display.  D) Placing a small rectangular piece of black tape over the "NOT" word on the display.  (See Picture) E) Reassemble.

Happily chose ANY compatible filter saving $20 to $30 each filter change!  (This filter too)
