How does it work?

Your charcoal is ready to use. Simply fill your bottle/carafe with drinking (potable) tap water and wait for the charcoal to filter impurities from the water. Leaving it overnight is ideal, but you will taste the difference after just one hour. Then, enjoy great tasting water!

Why use Binchotan

It may seem counter intuitive to purify your drinking water with a stick of charcoal, but the Japanese have been doing it for centuries. 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.

How long does it last?

With time, you will notice a decrease in the filter’s effectiveness on the water taste. You can then recharge it by simply boiling it for ten minutes. The boiling washes out the impurities and frees the charcoal up to absorb some more. Some people have more sensitive taste buds than others so if you notice the decline in taste before 3 months has passed, then it is absolutely fine to boil it at that stage too. Giving it a total life span of six months, as long as it delivers the desired effect, it means it is working!

Broken charcoal?

It still works just the same!

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.
