Binchotan active charcoal is used to filter water by absorbing impurities such as chlorine, and adding minerals such as calcium. These charcoal refills are pre-washed so they are ready for immediate use.
Drop the charcoal into your water, we recommend one stick per litre, then leave for 1 hour and enjoy your filtered water.
Each charcoal will last for 6 months as a water filter. They are then recyclable for other uses around the home, such as plant fertiliser.
