Product review (5 stars): GE Smart Water  MWF water  filter.
A perfect replacement filter for the GE Profile refrigerator. It is equivalent to original GE filters because it IS a GE filter.  Our GE side by side refrigerator has orange and red indicator lights to let you know it is time to change the filter. The orange is a warning that it is near time to replace, and the red is a "change me now" indicator.  I always change the filter soon after the orange light comes on and don't know how much leeway there is between the two lights.  Under our normal use, a filter will last about 11 months.

The taste of the ice and water from this filter is equivalent to or better than most bottled spring water or commercial ice.  That is saying a lot as the water in central Florida has a great deal of mineral content that detracts from the taste of our city water.

Originally I purchased these from GE directly and they impose a 3 unit minimum and added shipping to the cost.  By purchasing from Amazon.com, I am getting a lower initial price and can purchase single units as needed with free shipping. Now I don't have to tie up over $100 to keep a three year supply of filters hanging around. Again, thanks, Amazon.
