Sterile Water Vs Distilled Water: Know The Difference

In today’s world, water safety has become the topmost priority of the people for the sake of the health of their loved ones or family.

Sometimes it becomes the most critical question in our life: what type of water is the safest to drink? Is it the municipality water? Is it the groundwater? Is it water that the water filters have filtered? And so forth.

Various options are available in the market, and any individual can get confused about the most suitable options. Sterile and distilled water are among the most common options and discussed topics regarding safety.

In this article, we will discuss sterile water vs distilled water advantages and disadvantages. We will also discuss the difference between them and what should be your choice is,

What is Sterile Water?

What is Sterile Water?

We all know that a water source is full of disease-causing contaminants. When the water doesn’t have these living organisms in it, it is termed sterile water.

In simple words, we can define sterile water as a form of water where you will not find any disease-causing bacteria, protozoa, fungi, and viruses. You will be amazed to know that this type of water is used highly in the irrigation and the medical sector.

We will stick to drinking water in this article. It is far better than regular water. So, people consume sterile water to avoid contamination risks. This process can be done in your home with no requirement for modern equipment.

In this process, you have to boil the water for 20 minutes, raising the water’s temperature to around 250 F.

At this temperature, any microorganism or bacteria that may be present in the water can get killed. If you are concerned about the organisms or want to analyze the results before and after boiling the water for 20 minutes, you will require a microscope.

Through the microscope, you can easily visualize the absence of bacteria in the boiled water. You cannot see it through the naked eye because microorganisms are not visible to the human eye.

After the boiling process has been completed, you can directly drink the water after the temperature has cooled down. Don’t worry about the minerals and the essential nutrients, as they don’t get lost in the boiling process.

Boiling only kills the microorganisms from the water bodies.

Sometimes even after boiling, a vast possibility of contamination can occur because the bacteria can still float around and can play with the nutrients.

These nutrients are enough to make them survive in the water, so we will always recommend you perform a distillation process to prevent this process.

We will only recommend this complex process when you are suffering from a health condition because there is an infrequent possibility, and ‌it is not required.

If you don’t want to waste your time making your sterile water, you can easily buy it from medical supply companies or other research-based companies.

What is Distilled Water?

What is distilled water?

Do you know that nature follows a distillation process?

You might have encountered an evaporation process during your academic years, like how the water from the oceans or the water sources evaporates and forms clouds on a sunny day.

If not, rainwater is a product of nature’s distillation method. Whenever the temperature cools down,  the vapors are released back on earth as rain.

This is a very natural process that occurs on earth, but by following the same process, we can also make distilled water.

If you don’t know what distilled water is, it is a type of purification process that removes the organic materials, minerals, and salt from the water.

To simplify the process, we will break it into two parts: boiling and collecting the water into a clean container.

Process of Distilled Water

So the first step will be to fill the pot with water and boil the water for around 20 minutes. The pot should be tilted, so all the steams must be collected in the collecting container. The water in the collecting container is distilled water.

This process looks effortless, but is way more complex than you think.

When doing this process, it has to be in a controlled environment so that the water doesn’t become contaminated or it doesn’t come with any other equipment that can contaminate the distilled water.

Distilled water is a prevalent compound used in many kinds of laboratories. It is of great use, and. Very complex equipment is used to perform this process, which is left on throughout the entire day in a laboratory.

The steam is converted into water and collected into the container drop by drop. This is why it is time-consuming to use distilled water in a vast industry.

Using this filtration process at home, you can easily find out if your water is distilled or not. When you have collected the water, you can pour some water into the ice tray and let it convert into ice. 

After a particular time, you will find out that there will be a clear ice cube. If you have this type of ice cube, your water is distilled, but if you’re not, it’s still contaminated.

Apart from drinking, it has several other uses, and some of them are listed down below:

  • The unwanted chemicals can be removed from the hairs by rinsing them with distilled water.
  • You will get shiny utensils if you are using distilled water for washing their utensils. It will also remove every stain from your knives or glasses.
  • It is essential in the research laboratory, molecular studies, and other processes.
  • Distilled water is considered the purest form and is ‌beneficial for children, pregnant women, and people suffering from acute conditions. It is also important to note that you should follow the process after consulting with your doctor. We never know your other needs, so always communicate with your doctor.

Sterile Water VS Distilled Water

Sterile Water VS Distilled Water

In the above sections, we discussed distilled and sterile water in detail. We will discuss the differences between these water types and what you should choose.

  • The distilled water gently removes the inorganic and organic contaminants from the water, which is why they are considered the purest form of water. On the other hand, sterile water is not free from any inorganic chemicals. You can say that the distilled water is already clean, but the sterile water cannot be filtered. So, in clear terms, distilled water is much safer than clean water.
  • The major drawback of distilled water is that while removing the organic and inorganic products from the water, it also removes the essential components, for example, calcium. The water may be beneficial for you in some conditions, but in the other extremely deficient (of minerals and nutrients) conditions, it can’t be. So if you have any medical condition, you should always consult your doctor. On the other hand,  the sterile water only removes the disease-causing organisms.   It doesn’t play any role in extracting minerals or nutrients from the water.
  • The chances of recontamination in distilled and specialized water always remain a primary concern of the people. The sterilizing process does not require equipment and can be quickly done in the home. It must be done in a controlled environment and requires modern equipment, as you are collecting the steam here. You need to pan/pressure cooker and access heat; that is how you can easily make your sterilized water while the distillation process is very complex.

Frequently Asked Questions

What is the importance of sterile or distilled water?

Almost all the water sources in today’s world are contaminated, so it is essential to remove the organic and inorganic substances from the water. In addition to these disease-causing microorganisms, an abundance of them can be found in the water, so it is essential to take purified water by following any filtration process.

Which option should you choose if the water has many disease-causing microorganisms?

This is the most straightforward process that can be quickly done by just boiling the water for 20 minutes. In this situation, you should always ask for sterile water because the process kills living organisms from the water. These living forms mainly include spores, protozoa, fungi, and bacteria.

Which option should you choose if there are a high amount of organic and inorganic substances in the water?

The distillation process will be much more beneficial in removing organic and inorganic components from the water than sterilization. However, this process is more complex than the sterilization process.

Can these processes be used in combinations?

This method is considered the best option when you want to remove the organic, inorganic, and disease-causing microorganisms from the water. It is always recommended to follow the sterilization process before the distillation process. It is essential to remove the disease-causing microorganisms before the distillation process, as if the process is reversed, the chemical compound structure can change.


In this article, we have discussed sterile water and distilled water. The unique fact is that the process does not require considerable expense to invest in and can be quickly done in the home.

We hope that this article might help you to gain some knowledge. This would have helped you to make a proper decision on which water product you should invest in.

We will always recommend you conclude based on the benefits of a particular water type in your health.
