As an active carbon, charcoal works by attracting the negative ions in impurities like chlorine, and binding them to its surface. It has been used in Japan to purify and soften water for centuries.
Our binchotan charcoal can be used immediately - simply remove it from its packaging and place it in any bottle or jug. Once filled with water you’ll notice an improvement in taste after about an hour.
If used daily to filter 1.1L of water, each stick will last about 3 months. You can then “recharge” your charcoal stick by placing it in boiling water for 10 minutes. This process reactivates the charcoal and removes the contaminants that have been building up on its surface and allows it to filter your water for another 3 months.
Your charcoal will still work even when broken. However, if you’d prefer to buy another, you can still use the broken pieces in many different ways. To know more about this, have a look at our blog.
