It makes tap water taste great!

Binchotan active charcoal has been used in Japan as a water purifier since the 17th century. It reduces chlorine, mineralises the water and balances the pH. The binchotan active charcoal can be used for up to 6 months and amazingly recycles for many different uses after this.

Over 22 billion plastic water bottles are discarded around the world every year. We want to reduce this by making tap water taste better and encourage people to stop buying bottled water.

What is the history of Binchotan charcoal? 

The origins are not completely clear, but it is believed that a form of Binchotan charcoal (sometimes referred to as 'white charcoal') was introduced to Japan by a Japanese monk and scholar called Kukai 1,200 years ago. It was during the Edo Period (17th century) that a man calledBinchuya Chozaemon made it popular.

How is it made?

Sustainably sourced wood is placed in a kiln and charred at a relatively low temperature for some time, then, near the end of the process, the kiln temperature is raised to about 1000 degree Celsius to make the wood red-hot. The charcoal is then removed and quickly covered with a special powder made from earth, sand and ash, and this gives the charcoal surface a whitish hue (explaining the name 'white charcoal'). The rapid rise in temperature, followed by a rapid cooling, incinerates the bark and leaves a smooth, hard surface. If you strike it, you'll hear a clear, metallic sound.

How does it work?

Binchotan charcoal has an incredibly porous surface with tiny cavities oriented in many directions. Just 1 gram has a surface area in excess of 500 m2 (about one tenth the size of a football field). It is also known as active carbon as the ions of contaminants are attracted to the surface of the carbon, where they will be held. It is also able to release minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits.

How long will it last?

If you are using your Binchotan with our 'eau good' bottle and fill it up once a day, then it should last three months. You are then able to recharge it by boiling it in water for ten minutes and then leaving to
dry in sunlight. You should be able to keep recharging it for a further three months.
