Distilled water is steam from boiling water that has been cooled and returned to its liquid state. Distilling frees water of all the pollutants .Impurities in the original water that do not boil below or near the boiling point of water remain in the original container, the rest is the purified water. This process eliminates over 99.9% of the minerals dissolved in water. Distilled water is very safe and free of contaminants, because the process of distillation does not leave behind any minerals, chemicals or toxins what would deteriorate any of its usage. Though it is the safest form of water, it is not preferred for drinking because of its lack of mineral content. Distilled water is flat in taste and only contains hydrogen and oxygen. It is stripped of important minerals like calcium, sodium and magnesium.
