Product review (4 stars): I HAVE FAITH IN THIS PRODUCT
This is a "faith" review.  By that I mean I guess this filter is doing its job but that is because I have faith.  It's impossible to look inside the canister and evaluate the filters effectiveness.  I also don't have the ability to do a laboratory analysis.  However it did install as advertised and visually the water looks good and I can not detect any difference in taste.  So as I said, "I have faith that this GE Compatible Water Filter MWF GWF is doing its job."
