Difference Between Water and Distilled Water

Water is one of the most essential sources of life found on our planet. There are so many types of water, including regular water and distilled water.

The differences lie in the number of nutrients they carry and the process of purification they go through to be of use for various situations.

Water vs Distilled Water

The main difference between water and distilled water is that water contains a lot of minerals and impurities, whereas distilled water goes through a distillation process to get rid of all of the minerals and impurities. Water has a peculiar whereas distilled water has a very bland taste.

Water and Distilled Water

Water is a very versatile solvent. It is important for the sustenance of life on Earth. Not only is it important in the natural environmental processes, but it is also important for biological processes.

It is filled with minerals and nutrients that are required by your body but also contains many impurities which may be detrimental.

On the other hand, distilled water is purified water that goes through distillation, i.e., boiling and condensation, to get regular strip water of its minerals, nutrients, and impurities. You shouldn’t be drinking distilled water because of its lack of minerals which may be necessary for biological processes.

What is Water?

Water is an inorganic chemical substance that is one of the most important constituents of Earth and is a major source of life. It is an essential compound.

It has the ability to dissolve a lot of other things like salt, sugar, etc.

70% of the human body is made up of water which is used for various processes like biological processes and found in blood, digestive juices, etc. Water can appear blue in color if found in large quantities because of the absorption of light at red wavelengths.

Its chemical composition is H2O. It is a colorless liquid at room temperature and can be found in solid form as ice and in gas form as steam.

It is an extremely complicated compound.

Even though the solid-state of most substances is supposed to be denser than the liquid state, in water, the solid-state, i.e., ice, tends to float on liquid water.

It is also a natural habitat for a myriad of plants and animals. It can also be transported through the atmosphere in the form of vapor, after which it can condense and come down in the form of rain to facilitate plant and animal life.

It’s important to drink regular water as it has a lot of important nutrients like iron, magnesium, sodium, potassium, calcium, zinc, bicarbonate, etc.

What is Distilled Water?

Distilled water can be categorized as a type of purified water. It goes through a purification process which helps in the removal of all contaminants and minerals from regular water and only leaves behind the hydrogen and oxygen molecules.

The process of distillation includes boiling the water and then condensation, which will leave the contaminants behind. Distillation is very effective in the removal of heavy metals, minerals, and contaminants from regular water.

Since distillation includes boiling, most of the microorganisms present in water, like bacteria and viruses, also get killed.

Distilled water shouldn’t be your main source of hydration because it contains none of the minerals and nutrients that your body needs like zinc, calcium, magnesium, sodium, etc. The lack of these minerals also means that it has no taste and is very bland.

Some of the most common uses of distilled water as in lab experiments, scientific research, car cooling systems, steam irons, certain medical devices, etc. It is also beneficial for people with HIV or cancer since their immune systems won’t have to fight any infections as there will be no contaminants.

It can also be used in therapeutic regimens as it’s free for all impurities, which won’t add any excess pressure or trauma to a person’s digestive tract.

Main Differences Between Water and Distilled Water

  1. Water in its regular form has a lot of minerals and impurities mixed with it, but distilled water has no minerals or impurities in it.
  2. Water shouldn’t be used in scientific research or experiments due to the presence of excess impurities and minerals. However, distilled water can be used in scientific research and experiments as it doesn’t have any impurities.
  3. Water has a peculiar and good taste that people tend to like, whereas distilled water has no water.
  4. Water goes through no distillation process. On the other hand, distilled water goes through a distillation process, including boiling and condensation, to purify the water.
  5. It is advisable to drink regular water since it contains many necessary nutrients, whereas distilled water isn’t advisable to ingest since it is void of all the important nutrients like calcium and magnesium.
Difference Between Water and Distilled Water


Both regular water and distilled water are important in their own ways. Water has all the minerals and nutrients, whereas distilled water has no minerals or impurities since it has been purified.

Water is important in the sustenance of life forms and for the regulation of biological and environmental processes. On the other hand, distilled water is important for experiments and research purposes.

It is also useful for HIV and cancer patients because they have weaker immune systems and won’t have to fight any impurities.
