Berkey® PF-2™ water filters: Dissipation of Fluoride and Arsenic thanks to Aluminum Oxide

Berkey® PF-2™ water filters work to reduce fluoride and arsenic in water, acting through aluminum oxide, or activated alumina. It should be noted that pure aluminum and aluminum oxide differ significantly in terms of characteristics. Pure aluminum is water soluble, extremely reactive and can cause adverse health consequences. In contrast, aluminum oxide does not dissolve in water, remains inert, exhibits great stability and has no harmful impact on health.

It is also essential to specify that this aluminum oxide is not subjected to treatment with cyanuric acid.
