Product review (5 stars): Worked like a charm for my GE fridge--unscrew the old one, screw this one in!
I unscrewed my old filter. I took this one, filled it up with water as the instructions said, and carefully screwed it into place. There was no need to shut off the fridge or water supply or anything.

I ran it through a gallon of water as the instructions suggested, and the water came out tasting great!
