Product review (5 stars): Clean water for less
Have used these for  the past five years and Amazon was by far the cheapest.  The do it yourself stores where I purchased my refridgerator charges $40.00 a piece and the filter outlets $80.00 for three so this was a real bargain for me.  I now go to Amazon for anything I need and check it out before buying anywhere else - In most cases it really saves money.  These have provided excellent
clean water.
