Understanding the Difference Between Purified Water and Distilled Water

Understanding the Difference Between Purified Water and Distilled Water

Optimal water intake is paramount for your overall health. Each cell in your body relies on water to function effectively, highlighting the necessity to stay hydrated throughout the day. While most people know about the significance of water intake, there’s often confusion about the type of water to drink.

In this article, we will try to understand the difference between purified and distilled water to find out which one is the best choice for your hydration.

What is Purified Water?

Purified water is water that has been processed and filtered to remove impurities like dust, dirt, mud, bacteria, viruses, pathogens, chemicals, and toxins, making it suitable for human use.

Here are the impurities that are removed during purification:

  • Physical contaminants are dirt and dust particles caused by soil erosion and sedimentation
  • Chemical contaminants include metals, pesticides, and toxins
  • Biological contaminants consist of viruses, bacteria, protozoa, and parasites.
  • New-age contaminants include heavy metals like mercury, cadmium, arsenic, chromium, and lead, personal care products like cosmetics, shampoos, and hair dyes, and microplastics from the trash in our water bodies

Here are different methods used to purify water:

1. Reverse Osmosis

Reverse Osmosis (RO) is a purification technology that passes water through a semipermeable membrane to filter the excess Total Dissolved Solids (TDS) and impurities. They remove chemicals, pesticides, biological contaminants, and heavy metals like lead, mercury, and arsenic. RO purifiers are ideal for treating water with a TDS level of 500 to 2000 mg/l.

2. Ultraviolet

This purification technology employs ultraviolet rays at 253.7 nm to kill viruses and bacteria. It's fast and safe as it delivers water as pure as boiled water. UV purification is ideal for treating water with a TDS level of 1 to 200 mg/l. It can also be combined with RO to get RO+UV filtration.

3. Ultra Filtration

Ultra filtration delivers pure and safe water by eliminating bacterial contamination.1 It can be combined with RO and UV to provide superior purification.

Here are the benefits of having purified water:

1. Free of Impurities:

As mentioned before, purified water is devoid of harmful physical impurities, chemicals, toxins, bacteria, viruses, and pathogens.

2. Improved Taste and Odour:

Purified water often has a superior taste and smell compared to untreated water.

3. Reduced Health Risks:

Purified water lowers the risk of waterborne illnesses and health problems.

4. Versatility:

Suitable for drinking, cooking, and use in appliances without fear of contaminants.

What is Distilled Water?

Distilled water is a form of purified water obtained directly through the distillation process. This method involves boiling water and collecting the resulting steam, which returns to water upon cooling. This results in pure and clean water, free from physical impurities, minerals, bacteria, viruses, chemicals, and toxins. Distilled water is commonly used in laboratories and medical facilities.

Here are the impurities that are removed through distillation:

  • Viruses, bacteria, and protozoa
  • Chemicals such as sulfate and lead

Here are the benefits of distilled water:

1. High Purity:

Distillation removes pollutants and impurities, making it the purest form of water.

2. Ideal for Laboratory Use:

Recommended in laboratory experiments and medical settings for contaminant-free conditions.

3. Applications in Medicine:

Pure water is required for hygienic conditions in certain medical equipment and procedures.

4. Neutral Taste and Odor:

Distilled water typically lacks the taste and odours found in tap water, making it suitable for various uses.

Purified Water vs. Distilled Water: What Should You Choose

Both purified and distilled water are healthy for you. But, when it comes to choosing between the two, opt for purified water as it retains all the essential minerals like calcium and magnesium that are crucial for the healthy functioning of the human body. In fact, some water purifier manufacturers go the extra mile in retaining minerals in your purified water. For example, Aquaguard water purifiers come with Active Copper Booster Technology that infuses the right amount of copper into your water.
