Product review (5 stars): Great Price
What can I say, it filters the water.  My icemaker was not making ice and I scheduled a service call but the operator told me to try changing the water filter first as if it was clogged the fridge would not make ice.  The water output through the door seemed a little slower so I changed the filter and the problem was instantly solved.  I did have an extra filter which I ordered from Amazon when I changed the last filter.  You should always have a backup on hand IMO.. I cancelled the appt and the fridge is making ice fine now.
