The active charcoal “Binchotan” has been used in Japan since the 17th century to purify water. It reduces the chlorine content, brings minerals into the water and balances the pH value. You can use the active charcoal “Binchotan” for up to 3 months and can then be recycled as fuel for the BBQ.
This charcoal can be used in all kinds of drinking bottles or water carafes.
