You can be relatively certain the water inside a bottle is clean and pure when you first open it, but what about when you refill it from a tap or drinking fountain? That's where a water filter can help prevent you from getting sick, or just save your taste buds. And few look as easy to use as the WaterBean, which slips into a bottle and purifies the water with a few seconds of shaking.
