Product review (5 stars): Accept no substitutes
I made the mistake once of trying to save a few bucks by buying a "compatible" filter. Not only was it not shaped quite right, making it extremely difficult to install, but the filter left an off-note in the taste. I yanked it and quickly bought a real GE filter. Installation in my GE Side-by-side refrigerator is simple and the water and ice taste clean. The difference from knockoffs is really minimal spread out over the several-month life of the filter. Get the real thing; no regrets.
