Black+Blum Active Charcoal Water Filter

Binchotan active charcoal sticks that filter your water by absorbing chlorine and other impurities while adding minerals like calcium. Pre-washed and vacuum sealed, so they're ready to use straight away.

Drop one stick per litre into your water bottle or jug, leave for 1-8 hours (1 hour minimum for good filtration, 8 hours for great), and you're sorted. Works in any water bottle or container.

Each stick lasts about 6 months as a water filter, then you can recycle it around the house – works well as plant fertiliser or compost.
