Product review (5 stars): They fit. Not sure what else they do.
These work fine so far. No problems with install. Price is pretty good. To tell the truth, I can't tell if any of these charcoal filters do anything useful, or if they're just a way for somebody to make money. I've bought several brands over the past three years and they're all pretty much the same. Sometime if I'm not too lazy I'll do some research or experiments to learn what kind of algorithm the fridge uses to decide when to nag me about the stupid water filter.
