Product review (5 stars): Just as good as OEM for far less money
This filter fit my GE refrigerator perfectly.  I haven't had the water tested for contaminants, but the taste is excellent.  There is no taste of any minerals or metals in the water.  This filter seems to work just as well as an OEM filter.  Be sure to run 6 or 8 cups of water through the filter before drinking it or using it in a coffee maker, etc. to clear any loose charcoal.  The water initially comes out with several bits of fine charcoal, but clears up right away.
