This is the ideal way to bring filtered water on the go; the gym, the car, your bicycle, etc! Ideally placed in any 12-16 ounce water bottle, it begins working immediately bonding with toxins in tap water.

Kishu Charcoal is 97% pure activated carbon. It is extremely effective in bonding with toxins which may be found in tap water, including: lead, mercury, copper, cadmium (to name just a few).

Kishu Charcoal is made by Japanese artisans in an ancient process involving heating branches of a special oak tree in outdoor kilns over a week's time. This painstaking process shrinks and hardens the branches into activated charcoal - now able to readily adsorb toxins.
