KURO-Bō Stick

  • Purifies up to 3L of water per stick
  • Provides 3+ months of daily naturally purified water
  • The ultimate plastic-free and sustainable water filter
  • Extremely light and portable – ideal for both home and holidays
  • Ideally paired with KURO-Bō 100% Recycled Glass Water Dispensers
  • Recyclable in many eco-friendly ways

This innovative ancient natural water filtration technology, used for centuries in Japan (“Binchotan”), is unlike any traditional filter available today – both in terms of health benefits, as well as its incredible eco-friendly credentials.

Essentially nature’s own toxin magnet, KURO-Bō is a unique 100% natural, recyclable and plastic-free filter made of pure activated charcoal that is scientifically proven to:

  • Purify * (removes heavy metals/chemicals)
  • Mineralise * (adds minerals, e.g., Mg, Ca)
  • Improve taste and odour (removes Chlorine)
  • Remove bacteria * (E. coli)
  • balances an acidic pH *

By adding KURO-Bō Sticks or Kōins to your water at home, ideally in glass, ceramic or stainless steel, you are not risking exposure to potentially toxic plastic bottles and the risk of leaching chemicals. Furthermore, 100% of KURO-Bō’s product and packaging is sustainable, biodegradable/compostable and recyclable. KURO-Bō shouts loud and proud, a firm “N-O” to single-use plastic.

*Tested in a SANAS-accredited Water Laboratory in Cape Town


The first of its kind in Africa, and scientifically-proven, KURO-Bō Activated Charcoal Sticks are a completely plastic-free, sustainable and recyclable water purification solution. The ultimate next generation of water filter – for home or for travel.

A single stick of KURO-Bō Charcoal provides 3+ months of daily cartridge-free and naturally purified water. The charcoal stick will purify up to 3L of water at a time. For greater volumes, simply add extra sticks.

Activated charcoal, or Binchotan attracts and draws out positively-charged toxins (chemicals, heavy metals, E. coli) from your water, while depositing beneficial minerals and balancing an acidic pH.

How to Use

STEP 1: Remove KURO-Bō Stick or Kōins from the compostable wood cellulose bag. Boil in a shallow pan of tap water for 10 minutes. Allow to cool.

STEP 2: Fill your container or bottle with up to 3 litres of tap water for Sticks, and up to 1 litre for Kōins. Add the cooled KURO-Bō Charcoal to the water.

  • Whilst the natural purifying process begins immediately, wait 6 – 8 hours (Sticks) or 2-3 hours (Kōins) for the best results
  • More than 3 litres? Simply add one KURO-Bō Stick for every 3 litres
  • There is no need to remove the Stick or Kōins through the month; all you need to do is top up the water!
  • For water-dispensing fridges, KURO-Bō Sticks in the tank will give you purified water on tap!

STEP 3: Reactivating, Repurpose & Repurchase

  • After 1 month of daily use, boil your KURO-Bō Stick or Kōins for 10 minutes, allow to cool, and pop straight back into your water container
  • After the 2nd month, reactivate your KURO-Bō and reuse as before.
  • At this stage, repurchase KURO-Bō Sticks online
  • After 3 months, remove your KURO-Bō Sticks and either reactivate them once more (if your water still tastes sweet and smooth) or reinvent them!
