Meet bobble, a stylish and very smart way to make every drop of water you drink, better. bobble is a fun, reusable bottle that filters water as you drink. When water passes through the ingenious carbon filter, chlorine and organic contaminants are removed from ordinary tap water. Each replaceable bobble filter equates to 300 single-serve bottles so after 1 year, you alone have removed thousands of bottles from the environment, simply by filtering the water from your tap! bobble is a beautiful alternative to single-serve plastic water bottles, which harm the earth (and your wallet).
