Product review (1 stars): YOU MAY BE LOSING THE FLOURIDE AND BENEFICIAL MINERALS IN YOUR WATER.
Samsung would not provide me with an answer to my question even after two emails and one telephone call.  My query was whether these filters removed our beneficial fluoride and minerals.  I know what happens to teeth without fluoride even without sugar in my diet.  Was upset that they would not answer the question.  I am now using my city's tap water instead of the fridge dispenser of filtered water.  Also purchased a mouthwash that has fluoride.
