Purifying water bottle using binchotan charcoal water filtration system originating from 17th century Japan. A simple way to reduce plastic bottled water use - makes tap water taste great and is light weight to carry around. Simply drop and lock your charcoal into the bottle and fill with water. Filtration starts after an hour and tastes better the longer you wait. Used once a day, charcoal lasts for three months. You are then able to recharge it by boiling it in water for ten minutes and then leaving to dry in sunlight. Rechargeable for a further three months.
