Bobble water bottles do the work for you: they filter your water with a carbon-based filter that eliminates chlorine and other organic contaminants from the water as you sip. According to the company, one filter in a Bobble bottle equals about 300 bottled waters — imagine the money you’ll save. Best of all? It’s BPA-free, PVC-free, and free of phthalates. Plus, we love the fun colors and design.
