You can design the most stunning reusable water bottle in the world, but if people don’t like the taste of their tap water, they aren’t going to use it. Black + Blum’s new eau good bottle comes with a chunk of organic binchotan active charcoal that you can lock in place in a nook in the blow-molded bottle. After an activation time of six to eight hours, the charcoal improves the flavor of tap water by reducing chlorine, balancing pH, and adding minerals. The charcoal can be used for up to six months and then be recycled for other uses (replacement charcoal sticks can be purchased separately). Packaged in an unbleached graphic box, the bottle holds 27 fluid ounces and comes with a natural cork stopper. Available in April for $20.00 USD.
