A filtered water bottle that uses a traditional Japanese binchotan charcoal to make your tap water taste great. Designed with a cork stopper and a stainless steel wire that harken back to old Victorian bottles, it also has a modern aesthetic. The bottle is clear to reflect the purity of water, but made of BPA-free triton for durability. Each bottle comes with one binchotan active charcoal filter (6 months life.) Binchotan active charcoal has been used in Japan as a water purifier since the 17th century. It reduces chlorine, mineralizes the water, and balances the PH.
