Can You Drink Distilled Water?

bottled-waterWhen it comes to distilled water, many people have many questions, such as

  • Can you drink distilled water?
  • Is distilled water safe to drink?
  • How to make distilled water at home?
  • What is distilled water?

These questions suggest distilled water is controversial, and some people accept it, while others may say no to it.

Can You Drink Distilled Water? To answer this question, we need to know some facts. The answer may be different according to different factors.

What is distilled water?

To answer this question, we need to know how to make distilled water. As one way of water purification, distillation can distill any water. There are several types of distillation, but the basic principle is the same. We know that different matters have different boiling point. This phenomenon is obvious in a mixture. Water in a boiler is heated to the boiling point (about 100 centigrade). Other Chemicals which can boil off at a lower temperature will be collected and finally filtered out by a post-filter, while other substances or chemicals don’t boil are left in the boiler and liquid water becomes vapor and rises. When the water vapor is led to another container and finally condensed into its liquid form, then the liquid water is called distilled water that is of higher purity than its original water.

Can You Drink Distilled Water?

Generally, I should say you can drink it, because once the drink water (like well water, tap water etc.) is distilled, the water we get becomes much cleaner and more pure than before. It is safe to drink. However, we also need to know its disadvantages. Once obvious disadvantage is that all the natural minerals are removed using distillation. Therefore, compared with spring water or natural mineral water, distilled water is considered to be no better. Some minerals are beneficial to our heath, like iron, magnesium, calcium etc. On the other hand, if the water you want to drink contains many contaminants (like heavy metals, toxic organic compounds etc.), you may would like to drink distilled water.

You can buy bottled distilled water at a local grocery store, if you would like to. This is one source to get it. However, not all distilled water from different sources is safe to drink. Distilled water from industrial sources is not safe to use because of its lower purity. There are many other contaminants in it, making it unsafe to use.

Another factor may cause impure distilled water is the contaminated equipment you use to make distilled water. During the distillation process, some contaminants from the tubing and glassware may leach out, polluting the distilled water again. Both home distillation and commercial distillation have this problem.

If you use a home water distiller, make sure the boiling chamber is made of stainless steel, and the tubing is made of bronze, and the condenser is made of glass. You also need to clean it on a regular basis. If there is a post-filter, you also need to replace it on a regular basis, too.
