Health Effects of Fluoride

At levels above the EPA MCL of 4 mg/L, fluoride can cause skeletal fluorosis (bone pain, joint stiffness). The secondary standard of 2 mg/L is set to prevent dental fluorosis in children. At levels used in water fluoridation (0.7 mg/L), fluoride helps prevent tooth decay.

How to Remove Fluoride From Drinking Water

The most effective treatment for fluoride removal is Reverse Osmosis or Activated Alumina. Look for filters certified under NSF 58 standards.
