The science

KURO-Bō Activated Charcoal has undergone rigorous scientific testing*

These tests have reaffirmed KURO-Bō’s successful capacity for:

  • toxin, chemical and bacterial adsorption and removal from contaminated water
  • balancing an acidic pH of spiked water
  • enriching tap water with beneficial essential minerals

The process

Experience the incredible power of KURO-Bō Activated Charcoal, where rapid carbonisation leads to the expansion of hardwood’s internal pores, creating an extensive network for toxin adsorption.

At the microscopic level, this unique charcoal attracts positively-charged toxins and metals like chlorine, mercury and lead, effectively bonding with them and eliminating harmful elements from the water.

You’ll be amazed at how ordinary tap water transforms into a cleaner, sweeter and more delicious taste, all thanks to the adsorption capabilities of KURO-Bō Activated Charcoal.

Just a single gram of activated charcoal boasts an astonishing surface area of up to 1500m2, equivalent to six tennis courts combined. This vast surface area enables it to adsorb an impressive number of toxins, ensuring your water remains pure and safe to drink.

Both the KURO-Bō Stick or the pack of Kōins reach a saturation point after approximately 3-6 months of daily use, providing you with long-lasting, reliable toxin removal.

The reactivations

Unlock the full potential of your KURO-Bō with regular “reactivations.” Boiling your KURO-Bō Stick or Kōins on a monthly basis ensures that its pores remain open, maximizing the surface area for optimum toxin adsorption.

Rest assured, the reactivation process does not serve to “clean” the charcoal, nor does it release any previously adsorbed toxins and impurities back into the water – rigorous laboratory testing guarantees this.

As your KURO-Bō continues beyond the 3-month mark, more frequent reboiling every 2-3 weeks may be necessary to ensure the charcoal’s longevity and sustained effectiveness.

Please note that during the reactivation stages, there is a slight possibility of your Sticks or Kōins experiencing minor fractures due to the expansion and contraction of air within the pores during the heating and cooling process. However, this cosmetic change in appearance has no impact on the filter’s efficacy or overall lifespan. Your KURO-Bō filter will continue to provide you with pure, toxin-free water, maintaining its exceptional performance throughout.
