Product review (2 stars): Cloudy water... then it was just fine. Then it broke and needed to be removed.
UPDATE September 2017: We purchased a replacement filter of the same type. The original filter lasted quite a while. The replacement filter, at $45, lasted us about two months. It malfunctioned in a way that totally prevented any water flow from our refrigerator. We had to remove it in order to get the ice maker or in-door water dispenser to work. At that price, there should be ZERO malfunctions of this type.

We installed the filter and, like with the other reviews, the water came out a bit cloudy. I flushed the filter with about six to eight gallons, maybe. I feel like it was a bit more than the manufacturer recommends, but eventually the cloudiness went away. There was also an odd flavor when we finished flushing the filter. I'm not sure what it was, exactly, but we let the filter sit in place overnight and then I flushed it about another gallon. The flavor was gone and the water tastes fine.

The box says that it qualifies for three different types of NSF certification. The base two are the kinds most filters have, 44 and 61 or something like that. The third, NSF 401, is not all that common from what I read on the internet. So that is a definite plus. I know its a bit more expensive than the other filters out there, but to me, the NSF 401 certification makes it worth the cost.
