Black+Blum's Eau Good water bottle embraces the centuries-old use of active charcoal to make every day tap water taste better.
Hot on the heels of our story about CamelBak’s All Clear water bottle comes a variation on a similar theme. Whereas CamelBak’s innovation focuses on purifying unsafe water, however, UK-based Black+Blum’s Eau Good water bottle embraces the centuries-old use of active charcoal to make every day tap water taste better. Binchotan active charcoal — sometimes known as “white charcoal” — has been used in Japan as a water purifier since the 17th century, Black+Blum says, and is useful for reducing chlorine while mineralizing the water and balancing its pH. The sustainably sourced and rechargeable charcoal filter in the bottles can be used for up to six months, and is recyclable after that. After placing the filter in the bottle, users simply fill it with tap water and wait six to eight hours for filtration to take place. Priced at USD 20, the Eau Good bottle is made from BPA-free Tritan plastic, cork, stainless steel and silicon, and it comes with one Binchotan active charcoal filter, which can also be purchased separately for USD 3.70. The video below illustrates the concept in more detail: Black+Blum’s first batch of the Eau Good bottle sold out “within hours,” it says, but a restocking is scheduled for May. Retailers around the world, time to get in line?
