Now – Use your BottlesUp with your tap water, filter naturally with Kishu Charcoal
Kishu is the green way to filter your tap water. Your Kishu-filtered water tastes pure and sweet in our glass water bottles.
Kishu is 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.
Kishu is easy to use. Simply place the charcoal in our bottle of tap water, 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 six months and is completely compostable.
Save $2 when you buy a bottle with Kishu!
