What Is Distilled Water?

Distilled water is water that has been boiled, condensed, and then steamed back into a liquid form. The result is pure water without any harmful microorganisms, minerals or impurities.

Distillation can be complete or partial. In the former case, the process increases the concentration of certain elements, and the latter results in almost pure elements only.

The process of distillation depends on the components’ volatility.

Due to the lack of healthy minerals like calcium and magnesium in distilled water, it may taste bland or not right to people drinking mineral, filtered, or tap water.

There are different opinions on how beneficial it is to drink distilled water. Some oppose it as a sole drinking source, because of its lack of essential minerals, while others claim that it is a great way to detoxify the organism.

Distilled water is essential for some uses outside of drinking, including, uses in laboratories, and for medical procedures and tools, for the production of certain cosmetics, as well as for car batteries.

As for human consumption, distilled water is especially useful for mixing baby formula for babies with weak immune systems, for neti-pot rinsing of the sinuses, for adding it to CPAP machines and humidifiers, for use in irons and other appliances to prevent the build-up of scale, for washing your hair, for filling fish tanks, for cooking, cleaning, and other uses.

The pH level of distilled water

Distilled water, in theory, has a pH level of 7, which is neither alkaline nor acidic, but is known as neutral. It also lacks minerals. This is the reason why it tastes quite flat.

The problem is that as soon as you open the bottle or other container of distilled water, it starts dissolving carbon dioxide, and thus its pH level becomes lower, making the water more acidic. After a few hours in contact with open air, the distilled water can reach a pH level as low as 6, which is considered acidic and, according to some, can be harmful to your health. Read on to find out more about this fact, and other myths about drinking distilled water.

How do water distillers work?

Water distillation has been used by humans since ancient times to remove harmful and dangerous microbes and other impurities from the water.

Today, there are countertop and other home-distillers which you can easily use to make your own distilled water from tap or filtered water.

These units work by heating up and boiling the water in the reservoir until it turns into steam. After that, the steam is drawn through cooling coils where it cools down and condenses back into liquid form but without the impurities. The resulting distilled water is collected in a separate water tank. Meanwhile, the contaminants are either vented out of the unit or remain in the boiling chamber.

How do you maintain a water distiller?

Since the process of distillation separates the water from many of the minerals and contaminants which remain in the boiling chamber, they will gradually create a limescale build-up, just like hard water does on your faucets and other bathroom or kitchen fixtures. This means that you will need to clean it periodically if it doesn’t have a self-cleaning function.

To manually clean your water distiller’s chamber, you should remove and soak its lid, or if it is fixed, scrub it with a clean cloth with a vinegar or lemon and water solution, and then rinse it off.

The boiling chamber itself can be cleaned by using a 50:50 vinegar or lemon juice and water mixture. Add the mixture into the chamber, so it reaches above the build-up on its walls and let it sit overnight. On the next day, rinse it off with clean water and allow it to dry.

Do not use any commercial detergents except if they are recommended by the manufacturer of your water distiller. Any unchecked cleansers can contaminate your water and be harmful to your health.

To make maintenance easier, you may want to opt for a water distiller that has a self-cleaning function, like some of the ones on our water distillers list. This function allows for the machine to clean itself from the impurities without the need for scrubbing. In some cases, it will perform the cleaning automatically after each distillation cycle.

The benefits of using distilled water for drinking and cooking


Distilling the water helps remove many of the harmful components which may be lurking in your water no matter whether you rely on municipal water or a well. Some of the pollutants which can be removed by distillation include:

  • Nitrates and nitrites – which are especially harmful and can be dangerous for children and seniors
  • Barium – which can cause high blood pressure and heart problems
  • Copper – there is a correlation between developing Alzheimer’s and the intake of copper over a long period of time
  • Harmful microorganisms – nearly all known microorganisms are killed-off through the process of boiling, and they will remain in the container rather than move with the steam to the clean water tank
  • Chlorine – while chlorine is a highly efficient disinfectant, it has been linked to certain health conditions, and also can give the water an unpleasant taste and smell. Some people are especially sensitive to chlorine too

Overall, many people prefer to drink or use distilled water over other types of filtered water, because it is considered the purest of all types. This is the reason why it is essential for the medical, laboratory, cosmetics, automotive, and food processing industries.

Some people claim that distilled water can help people flush all toxins from their bodies and drink distilled water for a cleansing effect. The problem is that the missing healthy minerals in the distilled water need to be replaced to eliminate mineral deficiency problems.

More people are choosing to drink distilled water in order to save money in the long run. Making your own distilled water is cheaper than buying large quantities of bottled water.

Also, the water sold or stored in plastic bottles can have negative health effects on your health too.

What can you use distilled water for?

Apart from drinking it and staying hydrated, there are various other useful ways to utilize the distilled water you make at home.

Apart from being an essential element for medical and laboratory uses, distilled water is also used in other industries like cosmetics, food processing, automotive, and others.

But there are some practical uses for distilled water for home use as well, including:

  • You can increase the efficiency of your humidifier, and protect it from bacterial and other microorganism build-ups
  • It can keep the food you prepare and cook safe from harmful pollutants and chemicals
  • It is recommended for use for Continuous Positive Airway Pressure (CPAP) machines for sleep apnea
  • You can use it to prepare canned fruits and veggies, so they retain their beautiful vibrant color and fresh flavors
  • Neti pot sinus cleaning is more efficient and safer with distilled water
  • You can add distilled water when you need to top up your car battery or cool the car’s engine because it doesn’t cause corrosion to all the metal parts
  • Distilled water is much more efficient for cleaning windows, mirrors, cars, and other surfaces, especially if your tap water is hard and leaves a film or a residue from the minerals when used for washing and cleaning

  • Most new TV screens and monitors should be cleaned with distilled water only, according to their manufacturers, if you want to avoid unsightly streaks and smudges on them
  • Distilled water is suitable for filing aquariums, as long as you add the minerals your fish need to thrive, but avoid using it for small fish bowls or tanks, because it can be fatal due to the lower pH level!
  • By using distilled water for steam ironing, you will not only help avoid those splatter marks left by the hard water but will also prolong the longevity of your iron. The same goes for other home appliances which use tap water like coffee makers and others
  • You can use it to make safer and uncontaminated beverages like lemonade, tea, coffee, and others, as well as to make pure crystal clear ice
  • Distilled water is a safer option for mixing baby formula for babies and for those with weaker immune systems
  • It is safe and could be beneficial for your other pets like cats, dogs, bunnies, birds, and others
  • Rinsing or washing your hair with distilled water will make it healthier, shinier and softer

What about those common myths about drinking distilled water?

You probably have heard various theories and claims made by people who are pro or against drinking distilled water. While some have some truth in them, others are myths that can easily be busted.

Here are some of the most common myths about consuming distilled water:

Distilled water becomes acidic once in contact with air

Yes, it is true that the moment you expose distilled water to air, the carbon dioxide from the air contacts the molecules in the water, and the water absorbs it making the water acidic. Distilled water, just like rainwater, will become slightly acidic after being in contact with air. Still, its pH will reach about 6.0, which is very mildly acidic and much less acidic than Coca-Cola or even than a banana.

Your stomach has a pH of 1-2, so it is very acidic, so you don’t have to worry about drinking distilled water. Still, if you want to increase its pH level a tad, you can add a pinch of sodium bicarbonate, also known as baking soda to it.

Cooking with distilled water removes their healthy minerals and nutrients

When you boil or cook any type of food, you reduce its nutritional value, and this is especially true if you throw the water away.  Distilled water used in cooking acts in the same as regular water.

So, if you want to preserve the nutrients in your fruits, veggies, or other foods, try steaming them instead of boiling them, which will help.

In other words, when you are using distilled water for cooking, the only thing you are doing is preventing harmful components from entering the food you eat. Otherwise, distilled water has an effect on cooked food, which is not different from cooking with ordinary water.

Most of the unhealthy sweet sodas are made with distilled water

The most popular soft drinks on the market do not use distilled water, because this will make the manufacturing process much more complicated and expensive. The unhealthiness of these soft drinks is actually caused by ingredients like sugar, sweeteners, and other additives used for their production.

There are brands of distilled water drinks like “SMART” water produced by the Coca-Cola company, which is distilled water but with added salt. This is a hydrating beverage that you can easily make at home with the help of your home water distiller.

Drinking distilled water can cause a mineral deficiency

Yes, distilled water is stripped for all minerals, including the essential ones, like calcium, magnesium, potassium, or sodium. But drinking it can hardly cause any mineral deficiencies since regular mineral water contains so few minerals that it can hardly affect your overall mineral supply.

The truth is, humans, get their essential minerals and vitamins from the food they eat, and from supplements.

You cannot get the recommended amounts of minerals from drinking mineral water only. Hard water or mineral water can supply a maximum of 15% of the minerals that you need to be healthy if you drink the recommended amount of 8 glasses a day.

Drinking distilled water can be harmful to your teeth

Some people believe that distilled water, which is stripped from fluoride, can weaken the teeth. But given the fact that fluoride can be found in just about any toothpaste, you will get sufficient amounts to keep your teeth strong and healthy by simply washing them twice a day.

On the contrary, excessive intake of fluoride has been linked to the development of certain types of cancers, which is why many people turn to water filtration or distillation in the first place.

Distilled water doesn’t taste as good

Yes, due to its lack of any minerals, and added chemicals like chlorine, fluoride, and others, distilled water can taste different from the tap or filtered water you are used to. Then again, it is really a matter of taste and of getting used to.

Once you switch to drinking distilled water, you will find that it will gradually start tasting purer and better than the water you were used to drinking before, without the chemical odors and smells.

Distillation is not capable of removing VOCs

People have become increasingly worried about the effect of volatile organic compounds known as VOCs on their health. These are chemicals that are known to cause mild to severe health problems, and also can affect the taste of the water.

During the distillation process, the VOCs also enter the boiling container because of their lower boiling temperature. This means that the actual distillation process doesn’t remove the VOCs, so this is not simply a myth.

But thankfully, most of the good-quality water distillers have special vents for the VOCs to be removed from the boiling container before the steam cools down and turns back into liquid form. Also, the good quality distillers have added activated carbon filters, which are highly efficient in trapping and removing the VOCs too.

Water distillers need a lot of maintenance and cleaning

Some people refuse to buy and use water distillers because they believe that these appliances require too much work, and are not worth the effort.

Keep in mind that depending on your water quality, your distiller may need to be cleaned on a regular basis from the scale build-up inside the boiler chamber and the heating element. But if you have hard water, you will be performing the same type of cleaning for your bathroom and kitchen fixtures and appliances too.

The good news is, some of the high-quality water distillers have a self-cleaning function, which either starts automatically when the distillation process is done or which can be started manually by you.

Even if the distiller doesn’t have this type of function, it is easy to clean with a mixture of water and vinegar or lemon juice, or a dedicated cleaner, recommended by the manufacturer.

Usually, wiping the container off after use is enough to keep it clean and sanitary.

Water distilling is expensive

Although water distillers rely on electrical power to boil and distill the water, they usually use much less electricity per cycle than it would cost you to buy the same amount of bottled water.

Plus, using distilled water for your iron and other appliances can increase their longevity and help you avoid costly repairs and replacements due to scale build-up and clogging.

So, in the long run, using a water distiller instead of buying bottled water, or new appliances, will, in fact, help you save a lot of money.

Deionized, distilled, purified, spring, filtered or reverse osmosis water – which is the best?

You may be confused by the numerous different products for cleaning, purifying, and otherwise improving the water we drink there are available.

Well, given the huge variety, choosing which one is the perfect option could be quite overwhelming.

So, here are some basic differences, pros, and cons between distilled water and other types of purified, filtered, and improved water:

Distilled vs. purified water

Purified water is water that has been processed or otherwise filtered so that any harmful chemicals and contaminants are removed from it.

Some of the main impurities which are eliminated during the process include parasites, bacteria, fungi, algae, chemicals, heavy metals, and others.

In modern countries, public water sources are purified to make them safe for drinking and consumption. This is done by sedimentation, disinfection with chlorine or others, coagulation and flocculation, or filtration.

Further purification can be achieved via the home filtering systems, like whole house water filters, under sink filters, countertop filters, filtering pitchers, and others to remove chlorine, fluoride, and other contaminants.

Distilled water is derived through distillation and is purified from contaminants, but it is also cleared from any minerals and electrolytes. In both cases, the healthy minerals can be added to the water after purification or distilling.

Distilled vs. springwater

Springwater comes from natural sources – most commonly from spring. It usually undergoes certain filtration or other procedures so that any harmful bacteria are killed, but overall, spring water is pure natural water with a fresh and crisp taste. Its taste is mainly due to its high mineral content, which comes from the contact of the water with the rocks and minerals.

Springwater is highly sought for everyday hydration as well as for cooking due to its high mineral content, hydrating properties, and its fresh taste.

Distilled water, on the other hand, has no bacteria, and is much more purified than spring water, but it has no minerals in it either, which is why some people find that it tastes “flat.”

Distilled vs. deionized water

Deionized water has no other ions except for the OH- and H- ions. Deionized water is made via an electrically charged resin bed.

Deionized water is also free of minerals, and any other contaminants, and is considered highly pure and highly reactive. It comes into contact with air immediately after being exposed to it. As a result, its pH level is lowered to about 5.6, making it acidic after it connects with the carbon dioxide.

Keep in mind that deionization does not remove viruses, bacteria, or other uncharged particles, nor does it remove molecular species.

Deionized and distilled water are often used interchangeably, except when it has to come in contact with metals because, unlike distilled water, deionized water is corrosive.

Also, deionized water should not be consumed, because it may damage the tooth enamel and soft tissues.

Distilled vs. RO (reverse osmosis) water

Since reverse osmosis and distillation are the two most common methods for purifying water, they are often mistaken for one another. RO is a much newer purification method introduced in the 1970s, which today is among the most common methods which bottled water industries use.

A reverse osmosis system includes different components, including a pre-filter for sediments, a semipermeable membrane, an activated carbon filter, and may include a UV lamp.

RO works by pushing down water from one container through the membrane and filters towards the holding tank.

Reverse osmosis is known to remove a large percentage of the total dissolved substances (TDS) from the water, including trihalomethanes, VOCs, bacteria, and dissolved gases, as well as other pollutants, depending on the filters and systems used for the process.

So, in a way, RO water and distilled water are pretty similar due to the fact that they are high purity waters. The difference in their efficiency for purifying water depends on your water quality and the type of RO system you are planning on using. Both processes can remove different components depending on their boiling temperatures (for distillation) or on the filters used (reverse osmosis).

Distilled vs. filtered water

The quality and content of filtered water depend on the quality of the water treated and the filtration methods used.

In some cases, highly filtered water can be referred to as purified water because it has less than 10 ppm contaminants. In other cases, with simpler filtration methods used, the filtered water can remove some or more water contaminants.

So, which one is better largely depends on your water quality and grain rate, as well as on the filtration system you are using for your water.

Distilled vs. boiled water

Many people mistakenly think that boiled water is the same as distilled water.

The truth is, boiling the water is only half of the process, which turns regular water into distilled water. Although both start with the water being in liquid form and then transforming into a gaseous state after the boiling begins, with distilling, the steam produced is collected, cooled and transported into another container without the contaminants in it.

On the other hand, boiled water is water which has been boiled at 212 degrees Fahrenheit for 20 minutes, and during the process, the bacteria and other harmful microorganisms are killed by the high temperature. It is great for emergencies or disasters, as it can produce safe drinking water.

In boiled water, the minerals remain intact, and thus it does not lose its taste, unlike distilled water.

Boiled water is a much faster and easier way to make water safe for drinking than distillation. But the resulting water content is different, and so is its taste and properties.

Distilled vs. mineral water

Mineral water is basically spring water with added minerals. Due to the added minerals, some people may find the taste of mineral water as not as natural as spring water.

Distilled water, on the other hand, has all minerals and electrolytes removed from it, but it also has the toxic chemicals and metals removed from it as well. It may taste flat and funny to people used to drinking spring, mineral or tap water, but if you want pure water which is safe for drinking, then distilled water is a pretty safe choice.

Distilled vs. sterile water

Both are considered “pure waters,” but sterile water is used in the medical field for treating wounds, IVs, and other medical procedures. Distilled water is still used in some cases, especially by dentists who use it as a disinfectant and for rinsing the mouths of patients.

But the two are different. Due to its medical use, sterile water has a very specific osmolality and pH level, and although it is completely pure, it can be harmful if not used properly.
