When fluoride is added to municipal water it's not considerated a contaminant. But some people feel it's dangerous and damaging to our health. So, we provide fluoride reduction filters that will remove 80 to 90 percent. Fluoride is also naturally occurring in well water. It's a fact that above 4 ppm it can cause bone disease (pain and tenderness of the bones). Children may get mottled teeth. MCL 4 ppm.
