Biocera filters are a blend of the following ceramics:
Alkaline Antioxidant Minerals, which make your water more alkaline and change the oxidation reduction potential of your water. These are calcium, magnesium, sodium and potassium.
Pi Minerals, which increases water absorption and natural healing ability.
Tourmaline, which reduces water molecular cluster size, and emits far infrared rays which are thought to have healing properties.
The ceramic materials are manufactured by Biocera: one of the leading companies in the development of bioceramics for healing purposes. The ceramics have NSF approval. Biocera is the first company to have gained this international safety approval standard for ceramic minerals.
