Product review (3 stars): GE compatible MWF water filter
Was half the price of the GE product.  Seems fully functional, i.e., water's clear, no after taste, etc, but doesn't fully snap into place like the GE, it simply turns to the stop.  Will periodically sound like the water is refilling in the filter similar to the sound of turning on the tap in your sink.  Possibly air in the line but there's no evidence of such.  Since I only change it once a year (there's only two of us) will probably go back to the GE product and pay the added $$.
