Product review (4 stars): Not NSF/ANSI 53 Certified
This is not made to the same specifications as the GE filter.  The GE filter meets NSF/ANSI 42 and 53.  This filter is only tested and certified for NSF/ANSI 42.  If you are really concerned about your water quality you should pay for the GE filter, or one that meets or exceeds NSF/ANSI 42 and 53.  My wife stopped complaining about the water taste and smell, and she can't tell the difference from the original GE filter, so I gave it 4 stars.
