For years, cities and towns have added fluoride to the water supply in an effort to prevent tooth decay. While there are people that see this as beneficial, many consider fluoride to be a dangerous toxin, and in the right concentration it can actually be detrimental to tooth structure. In addition to the municipal addition of fluoride, there are other processes that can raise fluoride levels in the water; glass, steel, and aluminum manufacturers release high concentrations of fluoride with their waste water. You can find organic fluoride in fruits, nuts and vegetables and the aluminum industry releases an inorganic fluoride more commonly known as sodium fluoride. With all these variables, a fluoride water filter can protect you and your family from this controversial mineral and provide you with great tasting water.
