How to be BPA Free

BPA or bisphenol A, is a chemical in polycarbonate that is found in some plastic water bottles and baby bottles. Why do you want to be BPA free? Because studies have shown that exposure to BPA may cause adverse reproductive or developmental effects in people.

Difficulty: Easy

Instructions

1. Check the bottom of your water container. If your bottle is stamped with a #7 on the bottom, and is clear and rigid, it is likely that it contains BPA. There are a few BPA free bottles made from Eastman Tritan copolyester that will also be stamped with a #7. However, those plastic containers will be soft and pliable.

2. 
   Metal bottle

   Try switching to a metal container. There are ones made by Sigg, Klean Kanteen, and more, that come in a variety of sizes and uses. If metal isn't your thing, then look for a manufacturer that produces BPA free bottles. Nalgene is one that comes to mind. In addition, Walmart refuses to stock any containers with BPA, so you could shop for one there.

3. 
   Be sure to check your baby bottles

   Baby bottles are of particular concern, because if you heat one that contains BPA, there is a greater risk that the chemical will leach into the fluid. Born Free,and ThinkBaby produce BPA free bottles. Even Gerber makes one. Look for prominent labeling of BPA-Free on their packages as they also make ones that do contain the chemical.
