Premium quality: Our Binchotan charcoal sticks from Kishu are easily submersible in water. They don't float, they don't break, and they don't leave any unpleasant residue in your drink. Healthier water: activated charcoal filters water by absorbing heavy metal particles and chemicals and releasing beneficial trace elements instead. Forest conservation: The oak forests of Wakayama where our activated charcoals come from are responsibly managed to allow for natural regeneration. Good for the planet: Choosing our filtering charcoals means saving money from water bottles and, above all, rejecting the accumulation of single-use plastic. Discover a more natural way to filter water. Add Binchotan Activated Charcoal by Ajima to your cart TODAY!
