Kishu Charcoal

Keep Your Water Clean

Filter your water naturally with Kishu Charcoal, a unique charcoal used by the Japanese for centuries to purify drinking water. Holm oak trees are sustainably harvested then slowly fired in traditional kiln ovens over many days. Easy to use. Simply place the charcoal in your bottle, where it immediately begins absorbing impurities and imparting healthy minerals like calcium and potassium. Let sit overnight for optimal absorption. A single piece lasts up to four months and is completely compostable.
