We’ve seen other self-filtering water bottles, but none have been as adorable as the Bobble ($9.95), which comes in six colors and has a curvy, easy-to-grip shape, courtesy of designer Karim Rashid. It works as well as it looks. Just fill ‘er up, and then when you’re in need of some hydration, give it a squeeze to shoot water through the replaceable carbon filter to the mouthpiece.
