Product Description

Activated alumina is aluminum oxide, the same chemical substance as sapphire and rubies, but without the impurities that give the gems their color.

(This is not aluminum, which is a more highly-processed metal made from activated alumina.)

Activated alumina has a very high surface-area-to-weight ratio, with many tunnel-like pores that run all through it. This media features high surface area against which the water interacts, thereby removing fluoride (and arsenic). Through the attraction of the metals, 90%+ of fluoride (and arsenic) is normally removed. The fluoride coats the surface of the alumina over time and eventually the cartridge needs to be replaced (usually once a year for a family of four).
