We recommend to use three pieces of bamboo charcoal per litre of water.

  1. Rinse the bamboo under cold water
  2. Boil it for 5 minutes and let it dry in the sun. This will ensure a full sterilisation.
  3. Place your bamboo charcoal in your water bottle and fill it with tap water.
  4. Let it sit for one hour and drink it up!

We recommend sterilizing the bamboo once a week by repeating point 2.

Your charcoal bamboo filter should last around 3-4 weeks depending on the quality of your tap water and your consumption's level.

You'll know it's time to replace it once you won't see any more bubbles on its surface.

Bamboo Charcoal Natural Rice Cooking Filter


Bamboo charcoal has a ten times higher adsorptive power than other wooden charcoals (such as binchotan made from oak trees) thanks to its surface area of 300 square meter per gram and because it contains many mineral components such as magnesium, potassium, calcium and silicic acid you will be making your own mineral water!

The high-quality domestic Moso bamboo used as a raw material for this bamboo charcoal filter does not use any chemicals, pesticides, chemical fertilizers, and it's cut only when it reaches full maturity. 

Originally from China, Moso Bamboo has quickly spread in Japan thanks to its quick growth: it takes only three months for the Moso Bamboo to grow from bamboo shoots to its full height. Its tremendous growth speed makes Bamboo a sustainable natural resource that is unmatched by other types of woods.
