Water is the most important ingredient in your body. It makes up 60-70% of your weight, 70% of your brain and nearly 90% of your lungs. Your blood contains 83% water, and even your bones, which you’d think were dry as, well, bone, contain 22% water.

What’s all that water doing, sloshing around inside you? It regulates your temperature, helps digest food, flushes toxins out of organs, carries nutrients to your cells and assists with other vital functions.

For adults, a common guideline is to drink eight, eight-ounce glasses a day, depending on your health and activity level. But with more than 300 contaminants found in common tap water, including chlorine, ions of dissolved heavy metals, nitrates, pharmaceuticals, pesticides and more, ingesting these impurities may increase the risk of cardiovascular, oncological and allergic diseases.

You might want to think twice before you pour your family anything less than a BARRIER^®-filtered glass of water.
