A charcoal refill for the black+blum Charcoal Water Filter, used to improve the taste of tap water in your drinks bottle. 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 improves the taste of tap water.
The Charcoal Filter Range range from black+blum was created to help prevent environmental damage and waste caused by single-use plastic bottles. These charcoal refills are pre-washed and vacuum-sealed so they're ready for immediate use. Simply drop the natural charcoal into your water, one stick per litre, then leave for 1 hour (8 is best) and enjoy your filtered water.
Each charcoal stick will last for 6 months as a water filter. Simply recharge after the first 3 months of use. They're then recyclable for other uses around the home such as adding to your plants to help them grow.
