From the successful Charcoal Filter Range by Black+Blum, Binchotan active charcoal is used to filter water by absorbing impurities such as chlorine.

It has been used by the Japanese for over 500 years and will make your tap water taste great. This range was created to encourage people to stop buying expensive bottled water and adding to the continuing single-use plastic global environmental problem.

These charcoal refills are pre-washed and vacuum sealed so they are ready for immediate use. Simply drop the charcoal into your water, we recommend one stick per litre, then leave for 1 hour (8 is best) and enjoy your filtered water. 

Each charcoal will last for 6 months as a water filter, simply recharge after the first 3 months use. They are then recyclable for other uses around the home. They fit in Eau Good, Eau Good Glass, Eau Carafe and all our water bottles but can also be used any jug or bottle.

Binchotan active charcoal

Recharge the charcoal after 3 months of usage; boil in water for 10 minutes and then leave to dry in sunlight.
