Product review (5 stars): Microchip vs. No Microchip
Overall Im pleased with these filters however, I may add that the taste isn't as pure as I anticipated it to be, maybe its just the Water Municipality location I live amongst ?
My particular GE Refrigerator filter manual stated to only use RPWFE Microchip ( which is considerably more expensive ) I took a chance and to my surprise this particular RWF ( No Microchip ) filter did in fact work fine and saved $$$$ my refrigerator is out of warranty which is why I took the chance.
NOTE**** I don't however, suggest you to take the chance that I did for it may void your warranty.**** GOOD LUCK.
