Product review (5 stars): Culligan IC-EZ-1 EZ-Change Icemaker/Drinking Water Filter, 3,000 Gallons
Easy installation with 1/4 inch hose.  Simply plug in the lines to the filter inlet and outlet, and connect the other ends to the water outlet and the ice maker/water valve.  Flush a few pitchers of water before drinking to take out the impurities of the new filter.

Great price, easy installation and excellent tasting water!!!!
