What exactly is distilled water?

This is the water that is produced after distillation, during which the substances or components in the tap water are removed via evaporation which is then followed by condensation. The process of distillation can result in the complete separation of all the elements or partial separation which increases the concentration of certain elements in the liquid.

Both depend on the volatility of the different components in the water.

Distilled water lacks oxygen and minerals which can make it taste flat, but thanks to the water filters in some distillers as well as the additional minerals you can add to the purified water, you can improve its taste and increase its pH and mineral content.

How do Water Distillers Work?


The water distillers from our list have heating elements that heat up the water in the tank to a boiling point. Most of them have thermostats that ensure that the temperature is just right without using too much electricity or without heating up the water too much.

As soon as the water turns into steam in the distiller chambers it is drawn back in where it cools down and condenses and thus turns into liquid once again. The newly produced purified water is collected into the water container, and any contaminants which are removed from it during the process remain in the boiling chamber.

What about the actual water distillation process?

Distilling water is one of the oldest ways discovered by humans to purify and filter water. The process includes heating up the water to a boiling temperature which turns into vapor. As it rises, it enters the cooling coils which help lower its temperature and turn it into condense and thus back into a liquid state. At this stage, the purified water is collected and stored in a clean container, ready for consumption or other use.

Some of the water distillers on our list have additional activated carbon filters which remove all remaining chemicals from the filtered water.

Using and maintaining a water distiller

Since during the process of distillation, the contaminants from the tap water remain in the steam chamber, it is very likely that limescale will start building up in it, and can hinder the proper operation of the unit. This means that you will need to clean our water distiller on a regular basis.

Thankfully, keeping the boiling chamber clean is usually easy with any of these excellent water distillers in our list.

For more efficient limescale removal and cleaning, you can soak the lid of the distiller in water mixed with a quarter of a cup of either lemon juice or apple vinegar. In case the lid cannot be removed, use a clean cloth to clean it with water and vinegar or lemon juice solution until it is clean.

You can clean the boiling chamber as well by using a solution of half water and half vinegar or lemon juice. Fill the chamber up with the solution above the maximum line in order to ensure that all minerals and other deposits are dissolved and removed. Let it sit overnight and rinse the chamber.

It is not recommended to use detergents to clean the boiling chamber because they can leave traces of potentially harmful chemicals inside your water distiller.

What are the benefits of drinking and using distilled water?

There are multiple health benefits of drinking distilled water, which include:

  • Removal of chlorine

By removing chlorine from the water you drink, you will reduce the harmful chemicals which you and your family ingest and thus reduce the risk of poisoning as well as of other adverse effects including the development of some types of cancer.

Also, chlorine can irritate the eyes and the skin, so you can use distilled water to shower and bathe as well.

  • Removal of other chemicals and potentially harmful pollutants

Distilled water is the purest water you can drink. It is used in laboratories, for medical purposes as well as for making perfumes.

If you want to limit the intake of harmful chemicals, you should opt for drinking distilled water, rather than tap water.

  • It doesn’t have Nitrates

Large quantities of Nitrates can be potentially dangerous for people with weakened immune systems, young children, and elderly people as well as for people with underlying health problems.

  • It doesn’t have Barium or Copper

Barium and Copper can often be found in tap water. Barium can cause cardiovascular health issues, and the intake of too much copper can lead to an increased risk of getting Alzheimer’s disease or to other serious health problems.

  • It contains no or fewer microorganisms

The process of distillation destroys most of the harmful microorganisms when the water reaches boiling temperature. So, consuming distilled water will reduce the risk of ingesting parasites, germs, viruses, or other potentially harmful microorganisms.

  • It will help improve your hair and skin

If you wash your skin and hair with distilled water you will reduce the risk of the buildup of minerals and other components on it which can eventually damage it or make it look lifeless and dull.

With distilled water, your skin will look fresher, and your hair will be shinier and more alive than ever.

  • It will help you save money

By making your own distilled water at home, you will no longer have to pay to buy bottled water. Also, your health will improve so you will reduce your medical bills and sick time as well. This means saving tons of money in the long run.

  • It will help you reduce your carbon footprint

Imagine the number of plastic water bottles you are currently throwing away every year. With a water distiller at home, you will reduce your harmful waste drastically and thus be kinder to nature by reducing your carbon footprint and the waste which is killing the Earth’s animals and nature.

  • It promotes a natural detox of the organism

Distilled water remains the perfect way to flush out all of the toxins from the body. By drinking purified water you will stay hydrated, and at the same time flush out your bodily organs from all of the harmful toxins and components.

  • It can improve the digestion

Since distilled water manages to free your body from toxins and pollutants, it can help improve your digestion system by making sure that your body is absorbing essential nutrients instead of any harmful components and substances.

  • It can help resolve unexplained health issues

Many people who suffer from eczema, skin irritation, unexplained headaches, brain fog, or other issues which have no obvious underlying cause may find that by drinking distilled water their bodies will stop reacting to the harmful components found in tap water, and these symptoms may disappear completely.

  • It can help you stay safe from bacterial or parasitic infections

By drinking distilled water, you and your family will be at a lower risk of developing parasitic or bacterial infections which are often caused by drinking contaminated water with harmful microorganisms.

What can you use distilled water for?


As mentioned above, you can use distilled water to drink it, cook with it and wash yourself and your utensils with it.

Still, there are numerous other uses for distilled water you should know about too:

  • Distilled water is used by doctors, dentists, and in labs
  • Distilled water is used for sterilizing surgical and other medical and dental instruments. It is also used by doctors for washing their hands and for scrubbing in before surgery. It is also often used for cleaning wounds, rinsing mouths, and others
  • In laboratories, distilled water is used for experiments, because it doesn’t have any microorganisms or other impurities which can affect the outcomes of the experiments.
  • It is also used for Continuous Positive Airway Pressure (CPAP) machines for people with sleep apnea or other disorders
  • Distilled water is very efficient for cleaning contact lenses, glasses, as well as mirrors, windows, and TV and computer screens because it is purified and does not leave white streaks and residues on the glass surface as normal tap water does
  • Distilled water is also used in the perfume industry and for making cosmetics
  • You can use distilled water to clean your lead-acid batteries and cool down the engine of your car as well
  • Usually, this type of filtered water is used for making canned foods, as it reduces the risk of contamination of the food and its spoilage or change of color
  • People use distilled water for cleansing their nasal passages as well
  • It can be used for babies who are 6 months old or older too
  • Air humidifiers at home function with distilled water as well, because it reduces the risk of growth of bacteria inside the units, as well as the minerals reduced in the air at home
  • Distilled water is also an excellent option for topping off a fish tank, especially if you notice that your aquarium is losing too much water due to evaporation. But remember that you shouldn’t use only distilled water to fill up the entire tank because its lack of minerals is not good for aquatic life
  • Distilled water is promoted as a weight loss solution as well. Since it has zero calories and helps keep you hydrated, distilled water can help you lose the extra weight and become fitter as well.

Comparing distilled water to other types of purified or filtered water

Distilled Water vs Purified Water

Purified water is usually the result of various and multiple filtering stages and processing. The purification process can remove up to 99.99% of all harmful contaminant. Purified water usually contains less than 10 PPM contaminants, while distilled water contains as little as 1 PMM contaminants.

The main difference between the two is the level of mineral content in each. Even though both types contain fewer minerals, purified water usually has more minerals than distilled water. Still, minerals can be added to the distilled water after the distillation.

Distilled Water vs Mineral Spring Water

Since spring water comes from natural water sources, it contains magnesium and calcium, which is why it has such a fresh taste. It is commonly used for drinking as well as for cooking and for everyday consumption due to its superb hydrating properties and its high mineral content.

Distilled water vs Deionized water

Deionized water is made through the process of reverse osmosis, deionizing membrane on distilled water. It is purer than distilled water because it has no ions other than OH- and H+. It is highly pure, highly reactive water.

Distilled water vs Filtered water

The difference between filtered and distilled water is the difference in the filtration process which can leave different impurities in filtered water. If you buy a bottle of filtered water, chances are that it has undergone more serious filtration and can be considered purified water.  But in other cases, filtered water could contain certain minerals and some microcontaminants.

Final words

With a good quality water distiller, you can be certain that the water you drink at home is safe and doesn’t contain any potentially harmful contaminants, including viruses, microbes, parasites, chemicals, and minerals.

Distilled water can also be used for various other purposes, such as in emergency situations when there is a contamination of your local water sources.

It is always a way to save money from buying bottled water and helps reduce plastic waste.

We hope that we have helped you find the perfect water distiller and that soon you will have your own means of making fresh, clean and completely pure water at home with one of these excellent devices!
