Water, the fluid of life and the shaper of the earth, is made from the simplest and most abundant element in the universe, hydrogen, joined to the vital gas oxygen. Two atoms pair with a single oxygen atom to establish the triple structure water H2O. Water the universal solvent, given sufficient time, will dissolve or suspend almost any material on earth.

Pure water, therefore, is a rare substance. In nature, water in its purest form is found in the water vapor that rises from the earth's surface. Nature's cleansing cycle consists of evaporation, condensation and precipitation. As water evaporates from the earth, it leaves behind any contaminants it may have collected. Distillation, the process whereby water is turned into steam, then directed, into condensing coils where it condenses back into water, can therefore be aptly described as nature's way of purifying water. No other process produces purity as nature intended.
