This might just by my favorite water bottle design EVER! Named “BU”, it stylishly marries natural components like charcoal filtration and bamboo with glass-like plastic to encourage reuse. Using traditional Japanese methods, the activated charcoal filter is made by simply cutting a piece of bamboo to size and placing it in a kiln. The designers at BU have also made the lid from bamboo, the fastest growing plant on the planet, in order to limit the use of plastic and all unnecessary features. DO want! Designer:
