Powerful purification. Kishu binchotan in its purest form.

Binchotan charcoal has been used in Japan for centuries to filter and purify water. Made in the region of Kishu, this eco-friendly water purifier draws unwanted chemicals out of the tap water, naturally softening and improving its taste for up to three months.

Simply add purifying binchotan charcoal sticks to a container of cold water. Wait 4-8 hours and enjoy, refilling the water as you use it. Unlike plastic filters, binchotan charcoal sticks are entirely biodegradable and can do wonders for garden soil

Each bag includes 4 charcoal sticks, roughly the same size — typically about 5" long and 1" wide.

Binchotan charcoal is activated by burning branches of oak at extremely high temperatures inside a specialized kiln. This process, called nerashi, carbonizes the structure of the wood and leaves behind countless porous cavities that naturally bond with toxins, trapping chemicals and other impurities commonly found in tap water.

one quarter pound of binchotan charcoal can purify up to one gallon of water, and will keep your water fresh and pure for three months.
