Active Charcoal Water Filter with Locking Coil

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. Upgrade any* bottle to a filter bottle. This stainless steel coil securely holds our 100% natural active charcoal filter, with no rattle and no scratches! It’s taste-neutral, easy to use and allows you to turn any* existing glass, steel or plastic bottle into a filter bottle. (*minimum spout opening 30mm / 1.2in)
