Kishu Japanese Binchotan is known for filtering out chemicals and heavy metals from tap water; however, it does not remove the minerals and trace elements essential to our bodies. Using activated charcoal as a filter allows you to avoid buying expensive and wasteful bottled water by using it to drink pure water. Orinko distributes only genuine Kishu Japanese Binchotan sourced from responsibly managed Ubamegashi holm oak forests in Japan. Therefore, the production of Kishu activated charcoal does not threaten the extinction of this tree species. Furthermore, to offset carbon emissions, 1% of the sale price of the charcoal distributed by Orinko is donated to a reforestation program.
