Product review (4 stars): Great Replacement Option
This filter works just as well as the more expensive one that the manufacturer offers.  The only complaint I have is that when you remove it a few ounces of water will leak out of where the filter screws in.  If I could leave four and a half stars I would because it is such a minor issue as I only have to replace it about twice a year.

Also, the water tastes great :-).
