Adya Clarity - The Truth about how and why it works

Adya Clarity removes fluoride in two ways: Adsorption to aluminum hydroxide (then filtered out) and ion exchange where the sulfate ion causes the fluoride ion to be released, leaving fluoride to associate with existing calcium in the water and/or to evaporate as a gas. Calcium fluoride is over 80 times less toxic than sodium fluoride.
