The rapid heating and cooling during the carbonisation, or Pyrolysis, process, and the resulting enlargement of the hardwood’s millions of internal pores, is what enables KURO-Bō Activated Charcoal to adsorb (note, adsorb not absorb) toxins:

The rapid heating and cooling during the carbonisation, or Pyrolysis, process, and the resulting enlargement of the hardwood’s millions of internal pores, is what enables KURO-Bō Activated Charcoal to adsorb (note, adsorb not absorb) toxins:



  • At a microscopic level, it attracts the positively-charged toxins and metals (Chlorine, Mercury and Lead, for example) which bind fast to the vast surface area, thereby removing the harmful elements from the water
  • Adsorption is what makes ordinary, municipal-treated tap water taste clean, sweet and delicious 
  • A single gram of activated charcoal can have a surface area of up to 1500m2 – essentially 6 times the surface area of a tennis court – which is why it can so efficiently adsorb as many toxins as it does!
  • Each KURO-Bō Stick or pack of Kōins reaches a saturation point after about 3-6 months of daily use, when the pore surface area is effectively covered with impurities and a fresh piece of charcoal is required.
