Water distillation is a proven method of producing crystal clear and purified drinking water. The method of boiling water and then distilling its vapors has been around for a long time. The main factor involved here is to heat the water to its boiling point. The method of heating can be electrical or gas stovetops, barbecues or even a campfire.
Various companies have produced differing types of distillers. An electric obviously needs a power source, as it contains an element for heating the water contained in the apparatus. Non-electric distillers can be placed directly onto a flame for heating the boiling chamber. Usually constructed of stainless steel, it is similar to a saucepan, with the distilling unit placed where the lid would normally be placed. Steam rises of course, and this is how all distillers capture and condense the now purified water.
All these units require some type of chamber or boiler where the water is first heated. The next stage is for the rising steam to be condensed, leaving behind the contaminants in the sourced water. Any gases produced are discharged from a vent to prevent recontamination of the purified water. The purified water is then collected in another storage container, usually via a tube connected to the distiller.
The boiling process kills off microorganisms, bacteria and viruses that might be living in the water. Boiling will also remove most soluble gases, such as chlorine, but others might re-condense into your distilled water if they are not vented off properly. The second part of the distilling process removes contaminants, including heavy metals (such as lead and mercury), rust and dirt particles, other dissolved solids and hundreds of other possible pollutants.
The resulting water is very pure – 99 percent of the contaminants have been removed. There is still an ongoing dispute, however, about the health benefits or health risks of only consuming distilled water. Everything has been removed from it, including potentially beneficial soluble salts and micro trace elements that are contained in mineral water.
Distilled water still remains the purest possible drinking water available, and perhaps if you take a good multivitamin tablet with it, you will add back the good elements that might have been removed. On the other hand, some experts claim that these inorganic minerals present in water can't actually be absorbed by the body anyway, and might actually be a cause of kidney stones; by drinking distilled water, you avoid this risk.
