Distilled vs Demineralized water

Distilled Vs Demineralized Water: How To Demineralize Water

Water is all around us. Approximately 71% of the Earth’s surface is covered in water.

That’s crazy! We need it to live and use it in many different ways. As a result, it is important to have a general understanding of the different types of water and their unique uses.

For example, there is purified water, spring water, distilled water, and even demineralized water. But, which one is the best choice for human consumption? Which one should be used for making baby formula? I think most people have a good understanding of water that is purified or derived from a spring, but not you might not grasp the idea of distilled versus demineralized water.

This blog post will give you an in-depth overview of distilled vs. demineralized water. In the end, you will know the best type of water for your usage.

What Is Distilled Water?

Distilled water is water after it has gone through a process of distillation. In simple terms, it has been boiled and then cooled to produce pure water. This process removes all impurities, including bacteria, viruses, inorganic minerals, and other organic materials. That is why distilled water is known as the purest form of water.

However, It is important to note that the water must be stored in a sterilized container to maintain its purity. The distillation process also removes salts, metals (including heavy metals), and minerals.

Volatile organic compounds and gasses can make their way through the distillation process due to these compounds having a lower boiling point than water. Usually, manufacturers will add in extra filtering processes to absorb any remaining compounds and gasses.

What Is Demineralized Water?

Demineralized water is water that has undergone demineralization. This type of water is created by passing it through resins that remove minerals and salts. The resulting water has a very low salt content and low conductivity. Demineralized water is often used in applications where pure water is required. While it is free from most minerals, some other contaminants may still be present.

The Usage of Distilled Vs Demineralized Water

Now that you understand the difference of distilled vs demineralized water, I will show you some of the usages of distilled vs demineralized water. This portion is especially useful for those with health problems or weak immune systems.

Why Is It Important to Use Distilled Water?

It is important to use distilled water because it is considered the purest water. The impurities in regular water can cause a number of problems. They can interfere with chemical reactions, clog pipes, and damage equipment. They can also be harmful to your health and be problematic for those with different health risks. Distilled water is pure water that does not contain any of these impurities. This makes it ideal for many applications, such as drinking, cooking, and cleaning.

Why Is It Important to Use Demineralized Water?

It is important to use demineralized water because it is a more economical to purify water. Just like distilled water, demineralized water is a form of water that is free from minerals and, therefore, can be a very beneficial water source. Through demineralization, you are left with more pure water, with a lack of minerals and salts. Demineralized water is often necessary for applications where mineral-free water is required. This makes it an ideal choice for many different purposes.

How To Make Demineralized Water Vs Distilled Water

How to Demineralize Water?

There are a few different ways to demineralize water. The most common way is to use an ion-exchange process. This process removes the minerals and salts from water by exchanging them for other ions.

Another common way is to use a reverse osmosis filter system. The Reverse Osmosis process removes the minerals and other impurities from water by forcing them through a semipermeable membrane.

How to Distill Water?

Distilling water is a simple process. All you need is a pot, some water, and a heat source. Boil the water, then collect the steam in a clean container. The steam will condense back into water, leaving all the impurities behind. You can also use a water distiller, which is a machine that uses heat to evaporate water and collect its purest form, known as distilled water. To use a water distiller, first fill the distiller’s chamber with water. Then, turn on the machine and let it heat the water until it begins to evaporate. The pure water vapor will rise into the distiller’s condenser, where it will be collected and cooled to form distilled water.

Is Distilled Water Demineralized?

Distilled water does not mean that it is demineralized. Distilled water is often used in medical

and scientific applications because it is free of harmful contaminants and minerals.

Is Demineralized Water The Same As Distilled Water?

Demineralized water, also known as deionized water, is not the same as distilled water.

Some industries use distilled water while some use demineralized water. Both these types of water are used in different industries for different purposes.

Demineralized or deionized water is made by the ion exchange process. This process involves passing water through a bed of ion-exchange resins. These resins attract and hold the mineral ions in the water. This process removes the mineral ions from the water and makes it deionized water.

On the other side, distilled water is created in another way. The distill process removes most of the impurities from the water. Distilled water is free of minerals and other impurities. Distilled water is used in industries where water needs to be absolutely free of impurities.

So, these were some of the differences between demineralized water and distilled water.

Where to Get Demineralized Water

The best place to get demineralized water may vary depending on your location and water quality. Depending on your area, you might be able to obtain some at the grocery store. Other potential demineralized water sources include water distillation systems, deionization systems, and reverse osmosis systems; it all depends on your preference.

FAQ for Distilled Versus Demineralized Water

1. Is demineralized water safe to drink?

According to the World Health Organization, demineralized water is not safe to drink. This is because demineralized water has had all of its minerals removed but it may still contain other contaminants.

2. Is distilled water safe to drink?

Distilled water is safe to drink. However, just because it is safe water to drink doesn’t mean it is a good idea. You might find that it has a flat taste because of the distilling process. The nice thing is that distilled water can last long as a water supply if stored properly. When it comes to distilled or purified water meant for home appliances, it can easily last a few years when unopened.

If you make your own distilled water at home, its quality is best for probably a week or so. The water might become stale. Of course, it’s still safe to drink and all, but you might want to discard it and go with a fresh batch. Distilled water can go bad if it’s exposed to the open air for too long. It can also go bad if it’s stored in an old, dirty, or rusty container. Distilled water can go bad more quickly than other types of water, because it’s free of things like chlorine and minerals.

3. Is Demineralized Water Good For You?

Demineralized water is not good for you. The World Health Organization has reported that consuming “demineralized” water compromises the mineral and water metabolism of the body and could cause a number of health problems, including but not limited to: constipation, joint pain, and fatigue. A better water option to drink would be anything that contains essential minerals, like mineral water.

4. What is the pH of demineralized water?

Typically water that has been deionized has a pH of 5.5 – 7.5. This is in the neutral range.

5. Is filtered water demineralized?

Filtered water is water that has been passed through a filter to remove impurities. How this is performed depends on the filtration process. Filtered water is demineralized if it flows through a reverse osmosis filter system because the process uses a semipermeable membrane to remove the minerals. The water that is left behind from the water filters can be called demineralized water.

6. Is distilled water expensive?

Distilled water is expensive to produce because of the amount of energy and water required to distill it. It costs about $1 per gallon to produce. This is much higher than the cost of tap water, which is typically less than $0.01 per gallon.

7. Is bottled water demineralized?

Some bottled water is demineralized. Bottled water is filtered using a variety of methods, depending on the brand. Some companies use reverse osmosis, while others use ultraviolet light or activated charcoal filters. If a company uses reverse osmosis to filter the water, bottled water is considered demineralized.


I hope this article helps you decide whether to use distilled or demineralized water for your application or usage.
