Product review (5 stars): These work great! And save a lot of money over bottled water.
Put this in your refrigerator and enjoy clean, filtered water without that "chlorine" taste you get from tap water. Far cheaper than bottled water! So far as I can tell, the taste is just as good at a much lower cost. Depending upon usage, these will go up to about six months between changes. The same water is used for making ice cubes so you get the same good taste if you drink "ice water" as I do.
