What’s the Difference between Distilled water vs Purified Water?

Most of us who want to drink the safest and purest water go for either distilled or purified water. There have been a lot of discussions though concerning distilled water vs purified water. Which is the better choice?

Some of us, for whatever reason, may have our own preference. Some choose whatever is available at the moment or what they can afford.

One thing is sure though – there is basically no difference between distilled and purified water in so far as being able to drink the safest and purest water.

Distilled water is a type of purified water, however, purified water is definitely not distilled water. To erase the confusion, let us try to answer the question: What’s the Difference between Distilled water vs Purified Water?

The main difference between distilled water and purified water is in the process the water undergoes to be pure.

Distilled water undergoes a one-step process- the distillation process.

Purified water undergoes a series of purifying processes – reverse osmosis, ion exchange, sand filtration and some other processes.

What is Safe Drinking Water?

To better appreciate the rationale between distilled water vs purified water, let us first look into the qualities that make good quality and healthy drinking water.

Water, regardless of source, are all the same. It contains two molecules of hydrogen (H2) and one molecule of Oxygen (O). We all know the symbol of water as H2O.

The main difference between water types are the chemicals and minerals that are found within water. Some of these are naturally found in water while some have been added for various reasons.

Drinking water that is safe for human consumption must comply with the standards of safety set by the U.S. Environmental Protection Agency.

Drinking water is safe for human consumption if it is:

  • Free of contaminants. Toxins including toxic metals, viruses, bacteria, radioactive substances, synthetic chemicals, and additives used for treating water such as fluoride and chlorine.
  • Rich in minerals. Minerals that are naturally found in water not remove when it undergoes certain processes.
  • Balanced pH. Healthy level of magnesium and calcium (alkaline minerals). Alkaline pH must be between 7.0 and 9.5

With all the different types of filtration systems and bottled water available, it can be difficult to choose which type of water is the best drinking water. If you have a clear understanding of distilled water vs purified water, the choice could be a lot easier.

Distilled water vs Purified Water?

What is Distilled Water?

This is water that comes from any source and goes through the distillation process. Distillation is a one-step process that involves the boiling of water to free it from any contaminants naturally found in water (various metals, organic and inorganic materials).

  • Water is heated until it reaches boiling point.
  • Water is converted to steam.
  • Chemicals and most contaminants that have lower boiling points than water are left behind.
  • Condensation converts steam to liquid form.

The distillation process is most effective in water with:

  • Heavy metals
  • Minerals and nitrates
  • Bacteria, viruses and fungi

Benzene and chlorine are vaporized but are not removed during the distillation process because their boiling point is lower than that of water. Charcoal is used to filter out these chemicals from distilled water.

Pros:

  • Safe. The distillation process gets rid of dangerous contaminants that can cause diseases. The distillation process collects water in purest form.
  • Gets rid of harmful substances in the body. Distilled water can be used for detoxification and replenishment of minerals in the body.
  • High in benefits, low in cost. Whether you buy bottled distilled water or invest in a distilled water machine, distilled water is relatively cheap.

Cons:

  • Contaminants with lower boiling point than water cannot be removed by the distillation process (chlorine, benzene).
  • It tastes flat making it tasteless.
  • Not energy-efficient. The distillation process can take some time.
  • Increases acidity of the body. When water is made pure through the distillation process, it becomes an acid absorber that makes your stomach release more acid.
  • Makes you mineral deficient. Takes away organic and inorganic minerals from your body.

Whats the Difference between Distilled water vs Purified Water

What is Purified Water?

This water may come from any source and is made pure through either through reverse osmosis, soft water system, water filters, de-ionization.

  • Reverse Osmosis. A filtration process that applies pressure in water through a fine filter. The filter blocks contaminants that are harmful to the health.
  • Soft water system. Hard minerals from water are removed through this potassium or salt based ion exchange system.
  • Water filters. Removes harmful organisms and viruses from water.
  • De-ionization. Frees water from any ions coming from pipes, soil and pollution, Resin filters attract positive and negative ions that have contaminants that are molecule charged.

Pros:

  • 99% chlorine-free. Chlorine is used to treat tap water and also is a disinfectant for swimming pools. Chlorine in drinking water is harmful to the health.
  • Free of harmful contaminants. Bacteria, viruses and other organisms that are harmful to the health.
  • Gets rid of more contaminants than distillation because it goes through more purification processes.
  • Good for cooking. Impurities in the water you used for cooking will affect the taste of food. It also does affect the taste of your coffee and tea.
  • Reverse osmosis is an easier and faster process than distillation.
  • Taste Good. With all impurities released and useful minerals intact, purified water tastes and smells good.

Cons:

  • Most essential minerals that are good for the health have been filtered out.
  • It takes long to process water.

What is the Best Choice?

While most essential minerals in water are lost in distilled and purified water, this should not be something to worry about. The main objective is to be able to obtain safe and clean drinking water free of all harmful contaminants. Food, and not water is the main source of the body for useful minerals.

Both distilled and purified water are free of most contaminants, impurities and bacteria. As mentioned above, distilled water is a type of purified water because both the distillation process (distilled water) and reverse osmosis (purified water) are technologies to purify water.

Whether you drink distilled or purified water, you are still drinking water that is best for you. Water cleanses your body regardless of whether it is distilled or purified.

No one will contest the fact that water is one of the healthiest and most affordable drink for your body. The difference between water types lies in their different characteristics.

There is no such thing as a good or bad choice when it comes to water. The only requirement is –it should be clean and safe.

Both distilled and purified water are clean, safe and fit for human consumption. They both also keep you healthy. The difference between distilled water vs purified waterlies in what is available, what is best suited for you and what you can afford.
