Kishu Charcoal was founded in 2011 as an alternative to the wasteful, plastic-encased water filter. Kishu Charcoal is the simple, green, elegant way to filtered tap water. The fired oak tree pieces, filled with micro-cavities, allows Kishu to bond with toxins, including lead, mercury, copper, cadmium and chlorine. Kishu also impart healthy minerals such as potassium, magnesium and phosphates.
