Hailing from South Africa, KURO-Bō is the ONLY scientifically-proven plastic-free water filter!

Each KURO-Bō Binochotan Stick and Kōin is produced in the heritage-infused Japanese process. Developed by generations of Wakayama’s resourceful charcoal artisans.

  • High-quality hardwood is expertly and sustainably harvested
  • The wood is baked by skilled artisans in a specialised kiln – first at a low temperature, then at a scorching 1200ºC – causing the wood to carbonise and activate, enlarging its pore structure to maximise toxin adsorption
  • 7 – 14 days later, the carbonised wood is removed from the kiln and smothered in a mixture of earth, sand and ash, giving it a whitish hue
  • Once cooled, the ‘white charcoal’ is carefully hand-cut into KURO-Bō Sticks and Kōins.


We’re delighted to be working with such an innovative little company and love being part of a global movement.
