Product review (1 stars): Just called GE - they offer no support for products like this filter bought on Amazon!  Am forced to throw it away.
At six months, I replaced the filter although water still tasted great. At 12 months, I bought and installed this one just as before.  After 2 weeks, the water has never tasted clean, and still tastes as if its totally unfiltered. I HATE IT!!, and now too late to return.
