This is a scam to make us buy the more expensive RPWFE filters with rfid tags. The half priced RPWF are identical minus the rfid tag but GE now blocks them working. Shame on you GE. You can get around it buy buying a bypass filter, removing its rfid tag and taping it to the sensor. Then you can use any rpwf compatible filters without having your water heals hostage over $50 filters.
