A traditional Japanese Binchotan charcoal filter that naturally filters your water and makes your tap water taste great.

How it works:


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 able to release minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits.

How long does it last?


If you are using a bottle/jug and fill it up once a day, then the filter 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.

  • 1x binchotan active charcoal filter (lasts for 6 months)
  • Pre-washed and ready to use
  • Can be used in any jug or bottle
  • L 12 cm / L 4.7''

When you have finished using your binchotan as a water filter, it still has many secondary uses. If you break it up and put it in your house plants, it will add nutrients to the soil that will help the plant to grow. Because of its porous surface, it can be used as a deodoriser to remove unwanted odors in your cat litter, laundry basket, nappy bin or shoes. Binchotan is also an effective moisture absorbent, and can help absorb humidity in the air if placed in a wardrobe.

Please note that the charcoal filter comes vacuum packed in plastic.
