No problem replacing GE filters in my Smartwater filter. In fact, I think they last longer - maybe 50% longer. Water tastes good β and we are very picky. I don't know if it doesn't filter as many pollutants or something, but if it didn't work, we'd try it. I see some negative reviews there, so let me make a suggestion: for the price, it's worth just getting one and trying it out before changing the whole system or looking for an expensive replacement. I made this a few months ago and now I'm ordering 2 more.
