Founded in 2009, Boxed Water is a brand of prepackaged water that comes in paper-based cartons instead of plastic bottles. The water is purified using ultraviolet, carbon, and reverse-osmosis filtration, and some say it's a more renewable option than bottled water and cans. Boxed water cartons are made from 76% paper, a sustainable material that comes from well-managed forests. The boxes are also BPA-free and 100% recyclable, and they're shipped flat to reduce the company's carbon footprint.
