Bisphenol-A, also known as BPA, is a chemical that is commonly used to make polycarbonate plastics and epoxy resins. Polycarbonate is the most common type of plastic used in clear water bottles. BPA has been linked to a variety of health issues, including cardiovascular disease, diabetes, cancer and early onset of puberty. The longer a liquid sits in a container made with BPA, the more of it leaches into that liquid. The hotter the liquid and the older the container, the faster this leaching occurs.The controversy over BPA has escalated in recent years as more scientific data has accumulated. While government agencies such as the National Toxicology Program (NTP) and the Center for the Evaluation of Risks to Human Reproduction (CERHR) have called for a ban on BPA, the Food and Drug Administration believes these measures are premature and that more research is required. As a company, we place the utmost priority on the health safety of our products. While there is still debate over the health impact of BPA, we didn't want to leave anything to chance. That's why none of our products contain BPA.
