What is Water?

Water is a transparent and nearly colorless chemical substance. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water covers 71% of the Earth's surface. It is vital for all known forms of life. Safe drinking water is essential to humans and other life forms even though it provides no calories or organic nutrients. Your body is approximately 60 percent water, your brain is 70 percent water, and your lungs are nearly 90 percent water. Each day, your body must replace 2.4 liters -- or about 2.5 quarts of water -- through ingested liquid and foods. Your body uses water in many ways. Water cushions and lubricates joints; nourishes and protects the brain, spinal cord and other tissues; keeps the body's temperature normal; and helps remove waste through perspiration, bowel movements and urination. The best way to determine if you are getting enough water is to look at the color of your urine. If it is a pale straw color, you are probably drinking enough. If it is dark yellow, you may need to drink more. Humans require water with few impurities. Common impurities include metal salts and oxides, including copper, iron, calcium and lead. Using filters, like the four filters used in our True Water Bar Alkaline Water Ionizer, can ensure you that your water is rid of most, if not all, of these impurities.
