Product review (4 stars): Seems to work nearly as well as the official filters at a quarter of the cost.
Flavor does seem a little off. that said, it works. from what I can tell, the primary difference between this and the first party filters is the lack on these of pharmaceutical filtration.
That said, the last two GE filters we got, one leaked immediately after installation, the other seemed to freeze up the dispenser fairly regularly. since we've had these, we've had maybe two total dispenser freezes in 6 months. We used to get one every two weeks on the last GE filter.
