Eau Good

Reusable water bottle incorporates traditional charcoal filtration

From design powerhouse Black + Blum comes a stellar new alternative to wasteful disposable water bottles. Eau Good uses Binchō-tan, a traditional Japanese charcoal, to naturally filter tap water over the course of six hours. The plastic bottle has a small indent to hold the charcoal in place while drinking, and a simple squeeze releases the piece for replacement. Held in place with a metal ring, a natural cork stopper secures the opening.

Sourced from sustainably harvested timber, the charcoal is created by burning the wood at a precise 1000 degrees celsius. Once activated, the filter rids water of chlorine and other odors while balancing pH levels to deliver a natural, clean finish. While many filters currently use processed charcoal, Binchō-tan has a longer shelf life and is recyclable as a fertilizer and deodorizer. The charcoals—only $3.70 per piece—can be reactivated by boiling after three months for an average life of six months.

We recommend picking up a pair from the Black + Blum shop to keep your cold, clean water in constant rotation.
