Use a refillable water bottle instead of disposable plastic bottles, and you’re helping the environment. But many refillable water bottles are made of polycarbonate plastic that can leach BPA into water. Nalgene, one company that manufactures reusable bottles favored by many athletes and outdoor enthusiasts, has announced that it is phasing out production of bottles containing polycarbonate and now offers a wide range of BPA-free bottles and cups.
Avoid: Older Nalgene-type bottles and polycarbonate plastic bottles with the recycling number 7 stamped on the bottom.
Instead, try: Nalgene or other plastic water bottles labeled BPA-free, or stainless steel bottles such as the Klean Kanteen Classic (starting at $17.95 at KleanKanteen.com)
