Product review (5 stars): Does the Trick!
I love drinking fresh water, and don't like the chlorinated city water.  So, using the fridge filtered water works well for me and my family.  I never thought about a time frame for replacing the filter, but found a recommeded time of every 3 months.  Since I had severely overgone that time I went to Amazon to find the right filter....there it was... the GE  MXRC!  Very easy to replace.  Perfect for a replacement to the original product.  Enjoy!
