London-based design consultancy Black + Blum have designed a water bottle that ditches high-tech filtration for a more back-to-the-basics approach.

The water bottle, called Eau Good, contains a stick of active carbon called Binchotan, sourced from trees, and is the same stuff the Japanese have been using to filter their water for centuries. This eco-friendly stick works just like your Brita, filtering chlorine and other chemicals out, balancing the pH, and putting the good minerals back in.

Black + Blum designed the bottle to be easy on the eyes and kind to the environment. The charcoal stick sits snugly in a curvy BPA-free bottle, has a cork top, and filters for up to 6 months. When it’s time to exchange the filter, you can toss your old one in the compost.
