With a squeeze and a snap, 6 months of great tasting tap water is available at your fingertips. By providing a locking compartment for a tube of binchotan active charcoal in their cork-topped BPA-free bottle, designers Dan Black and Martin Blum have modernized this natural filter used by the Japanese since the 17th century.

Binchotan reduces chlorine, mineralizes water, and balances the pH so no additional filtration is necessary for pure, refreshing tap water. Maintaining the charcoal is easy, just remove it from the bottle after three months and boil it for ten minutes. Once you've recharged it, your tube is ready to transform your tap water for another three months.
