Got this to remove fluoride mostly, but found that it took care of the intermittent flavors as well-plastic, sulfur, chlorine  (that the water company told me was my imagination) I never thought our tap water was bad, but now I can't drink it-It's easy to use-for a family of 4-we have two going at once. Filters last 10days (city water is ~155 before it goes through the filter) except in summer-when we go through them a little faster-it comes out to $50 a month for great non-fluorinated-smooth water. The water does get more acidic towards the end so we change the filter when it is 1.
 Wish they had a filter you could attach to taps. Great product though
