Hey there! The statement above is True. Fluoride tends to clean water a lot better than the other things they use. The only problem is, flouride isn't commonly found in it's original untouched state. In fact, getting flouride for drinking water is very tedious, and takes a lot of hard work. However, this seems to be the best element to treat water, and seems to work very well. Hope this helped!
Thanks!
