Product review (2 stars): Is not a fit for GE MWF.
It's a well made filter; however, it does not fit properly in a fridge made for a GE MWF filter.  When I was able to make it sit properly in the fridge no water would flow through the filter.  I think the hole at the top of the filter is too small when compared to a genuine GE replacement. I had to return the unit. Return was done w/ no problems.
