Product review (4 stars): Works as advertised
Direct refrigerator water filter replacement.  Installs easy and works fine.  Just pretty expensive, which is not Amazon's fault since they are ALL too expensive.  PLEASE NOTE:  When first installed, use the refrigerator water to fill up a glass pitcher or container until the water is clear.  I was alerted to this by reading reviews here on Amazon and sure enough..at first the water was kind of gray for the first couple of gallons.  I don't know what that is, but probably best not to drink it.
