How to filter your water with charcoal

Kishu Binchotan charcoal is an active carbon made from tree branches.  Due to its extremely porous structure, Binchotan charcoal is renowned for its ability to absorb impurities, unwanted tastes and odours from water such as chlorine and releasing beneficial natural minerals. It can also be used to purify indoor air, keep closets, drawers, and refrigerators free from odour, dampness and mould and improve the health of soil and plants.

 

Kishu charcoal is made from Japanese Holm oak, which grows on the forested hills of Kii Peninsula. Oak trees are not logged, but instead, branches are cut off selectively leaving the tree alive and healthy. To make Kishu Binchotan charcoal, oak branches are stacked inside kilns and baked at incredibly high temperatures over several weeks. Oxygen is then shut off and turned on again and its flow slowly increased. This centuries-old process turns wood into carbon, and at up to 98 per cent, Kishu Binchotan charcoal has the highest content of carbon of any charcoal making it one of the purest and highest quality charcoals available on Earth.

 

How to use Kishu Binchotan charcoal to filter water

1. Before using, boil the Kishu Binchotan charcoal stick for 10 minutes, remove and allow to and cool completely. It is now ready to be used. Re-boil the charcoal stick every two to three weeks to get rid of everything it has absorbed. Also, take care not to drop the charcoal stick as it is easily breakable.
    
2. To purify tap water for drinking, place the boiled and cooled Kishu Binchotan charcoal stick into a pitcher of water. Leave for a minimum of five hours, or overnight for best results. The charcoal stick will alkalise the water, absorb chemicals and toxins, and release beneficial minerals into the water. The charcoal stick will stay hard and not discolour the water. One stick will last for approximately three months if you boil it every second week.
    
3. Once your Binchotan charcoal stick has reached the end of its indoor life, improve soil health by recycling it in the garden. Break the charcoal stick up into pieces and mix it into new soil or apply it over a garden bed. The Binchotan charcoal will improve the movement of air and water through the sol, alkalise the soil, and reinforce trace elements.
