A water distiller turns water into steam to remove fluoride, arsenic, lead, viruses, and other contaminants. John Woodard, our Master Water Specialist explains how a water distiller works, whether or not distilled water is good for you, and which distiller is best. 

What is a water distiller? 

A water distiller uses a water treatment process that mimics mother nature's natural filtration process, the hydrologic cycle. The sun evaporates water, turns it into clouds, and returns it to the earth in the form of precipitation. A water distiller does the same thing.  

How does a water distiller work?

  1. The water distiller boils the water, turning it into steam.
  2. The steam is then condensed and cooled, returning it back to a liquid state.
  3. Anything that cannot turn into steam, like minerals and microorganisms, is left behind.

What does a water distiller remove?

  • Inorganic minerals like lead, arsenic, and fluoride. 
  • Microorganisms including viruses and bacteria.
  • Some chemicals

Microorganisms cannot survive the boiling and steaming process. When the water distiller boils water, it kills any bacteria and viruses that the liquid may contain. Removing these things from water, especially microorganisms and chemicals, are important to maintaining health.

What are water distillers used for?

In applications where water must be relatively mineral free, like in a laboratory or medical application, distilled water is the best choice. Distilled water is often used simply for cooking, making baby formulas, or for drinking.

How do I choose the best water distiller?

There are a variety of water distillers available for you to use, but not all of them may be suitable for your needs. The best question to ask yourself when searching for the right water distiller is, “which one will make enough water to meet my demand?” If you have 20 people in an office drinking the water, you'll need something capable of generating and storing enough water for your office staff to drink. A homeowner, with just a few people at the house using water, may prefer a simple countertop distiller to meet their needs.  

Most water distillers have a capacity to hold anywhere between three and twelve gallons of distilled water. So, choosing the right water distiller may not be such a difficult task. Another way to decide which one is best for you is to find out what the distiller is made of. Sometimes, stainless-steel and glass distiller systems are preferred over plastic because of the chemicals that it leaves behind.

Is distilled water really a healthier choice than tap water?

Distilled water is healthy to drink. It removes inorganic minerals, microbiological organisms, and most chemicals, making it clean and safe to use. Whether distilled water leaches minerals out of the water and strips your body of those essential minerals is controversial. However, we acquire most of the essential minerals for bodily function through the fruits and vegetables that we ingest. With that in mind, the small amount of mineral content commonly found in water is not significant enough to make a difference in our health if absent from our water supply. 

Clean, high-quality water is still very important to us. Water hydrates and lubricates our bodies so that we function properly. Because our bodies are made up of water, 70- 80 percent, we should be sure that the water we consume remains high-quality so that organs like our kidneys do not over-work themselves to filter out unnecessary solids. 

Isn’t tap water already treated? 

Municipally treated water is supposed to meet certain guidelines. Water treatment professionals generally do a good job making sure the water that runs through their system is safe to drink. But, it's possible for their large, complex systems get damaged. In which case, the tap water could be contaminated until they fix the issue. So, protecting our drinking water by using a distiller is beneficial in ensuring that you have clean water.

Can a water distiller be used to distill alcohol?

A water distiller can be used to distill alcohol; however, it is illegal unless you have a permit to do so.
