Kishu Charcoal was born in 2011 as an alternative to plastic water filters. Determined to find an eco-friendly, plastic-free way to filter tap water, we came across a material used in Japan for thousands of years. Made by artisans, using traditional methods and handmade kilns, Kishu Charcoal is brought to life from sustainably harvested oak branches slowly carbonized to 1000 degrees. After a number of days, a beautiful and glass-like activated charcoal emerges. Kishu Charcoal is… …the only completely plastic-free water filter. …made from the finest Japanese activated charcoal. …individually hand cut — every stick is different. …produces the most delicious tasting tap water.
