Product review (3 stars): Caution Mwf filters are now much harder to install.
See UPDATE below. This filter does not fit my GE Profile refrigerator which uses Mwf filters. It appears that the inlet on your filter is smaller than my current Mwf filter. Yours is not the only filter that I have recently tried that does not fit my refrigerator; in the past I have not had this problem with a fit with Mwf compatible filters. I have called GE and ordered an mwfp filter directly from them that supposedly will fit my refrigerator, and hopefully it will.  UPDATE !  The GE filter appeared not to fit, but after calling GE and they did some research I was told that  the filters now have to be applied with greater force. After removing the shelf directly below the filter, I was able to apply enough force to the filter to install it. I suspect that this filter will fit  also, but at a much lower cost than the GE filter.
