Product review (4 stars): GE Cafe water filter
It is a water filter, it works, it filters water.  It is pricey.  We have found that the filters become obstructed in about 2 to 3 months which would be about half the claimed service life.  That makes them outrageously expensive.  Manufacturer which may be GE or Haier should fix this issue so one actually gets the claimed service life.
