Product review (4 stars): had me confused
my refrigerator uses the Smartwater filter, which I have bought several times from Amazon - but this recent purchase was confusing because the filter no longer states SmartWater on the filter itself, so I returned the one I got because did not say SmartWater on the filter - now just states MWF on filter, so I thought they sent the wrong one, after I got the exact same when I ordered again and talked to Amazon rep we discovered in one area it explained the Smartwater filter has been upgraded and now is the MWF filter without the SmartWater words on it - supposed to filter out a few more things - can't tell any difference, but gave 4 starts cause Amazon need to get the description of this new filter better clarified.
