Product review (1 stars): No Good Alternative.
Purchased current refrigerator few years ago specifically due to PUR water filter accessory. Have tested other refrigerator filters and PUR is the best I have ever used - unfortunately they are no longer available - have seen some random availability on Amazon for big bucks. Agree with other reviews of unpleasant taste and aftertaste. I always test the quality of a water filter by leaving a glass of water on the counter for a few hours then check for taste. Shouldn't have a taste!! This one fails big time. Taste is sadly very similar to tap water left in a glass for same period of time. I feel I now have no choice  - but have turned off the icemaker for now since melted ice in a drink will compromise the flavor and have purchased a PUR water tank for in the refrigerator. What a waste.
