Binchotan is an active carbon made from tree branches and is renowned for its ability to soften water, add good minerals and absorb unwanted tastes and odours, such as chlorine.Fill the bottle with water and add the charcoal. Leaving it overnight is ideal, but after an hour you can actually taste the difference. If you notice that the effectiveness of the filter decreases over time, you can recharge it by boiling it for ten minutes. Boiling rinses away the impurities and allows the charcoal to absorb more.- BPA-free- Made of hand blown borosilicate glass- Dishwasher safe- Charcoal included
