Water quality is important for a wide array of reasons. For fish to survive in their habitats, it’s important that their water remains clean. Drinking water also needs to be free from impurities in order for the people who drink it to be healthy. Water quality is a critical component for many industrial treatment applications. For instance, boiler water will need to be treated if too many impurities are found in the water. High amounts of impurities can lead to development of scale and a worsening of system efficiency, which is why many industrial facilities are required to treat their water on a regular basis.

There are a variety of different types of water, which include:

  • Purified water
  • Mineral water
  • Distilled water
  • Spring water

Understanding the differences between the various types of water should help you identify which option is best for you or the specific application that the water is being used for. The following offers a closer look at the primary differences between purified water and distilled water. Both purified water and distilled water have their own benefits, which is why you might want to know how they differ from one another.

What is Purified Water?

Purified water is a kind of water that has been effectively filtered with the goal of removing various impurities from the water. Purified water can be made from both tap water and groundwater, which means that it’s readily available for practically all homeowners.

The many impurities and contaminants that are removed from water during the purification process include:

  • Numerous chemical pollutants
  • Bacteria
  • Fungi
  • Algae
  • Certain metals like lead and copper
  • Different parasites

There are several different methods that can be used to purify water, which include:

  • Filtration
  • Sedimentation
  • Coagulation
  • Disinfection

While these four processes differ significantly in how they purify water, they are able to provide similar results. In order for water to be classified as purified water, it must have lower than 10 PPM, which means that around 99 percent of all contaminants must be removed from the water.

Health Benefits of Purified Water

Purified water is considered to be the healthiest type of water, which is why it comes with many notable health benefits. Even though standard tap water is usually safe to drink, this water can still consist of trace amounts of contaminants, which is why it’s recommended that you opt for purified water.

The many benefits of drinking purified water include:

  • Numerous purification methods eliminate chlorine in the water, which is a standard chemical that has been linked to a higher risk of colorectal cancer and similar cancers
  • Removes harmful bacteria that can lead to nausea, stomach aches, and various illnesses
  • Provides your skin with a protective barrier that keeps impurities out
  • Provides benefits to your colon and digestive tract
  • Removes metallic substances, organic matter, and chemicals, which should improve the taste of the water
  • Gets rid of heavy metals like lead and copper, both of which are highly toxic

You should drink purified water because it’s exceedingly healthy and is able to get rid of most of the contaminants that remain when you consume public drinking water. While the EPA has set guidelines that require public drinking water to be rid of at least 90 percent of contaminants, different states have their own guidelines. Even though state guidelines for public drinking water must be at or higher than the 90 percent removal rate for contaminants, some states have stricter regulations than others.

Drinking water that has been purified from 99 percent of contaminants is always going to be healthier than drinking water that still contains up to 10 percent contaminants. While purified water is healthy to drink, it’s recommended that you drink other types of water as well. Ultra pure water contains no electrolytes, which your body needs. A deficiency in electrolytes can lead to high blood pressure and other health problems.

Cons of Purified Water

The main issues with purified water include:

  • Certain purification systems will remove fluoride from the water, which is a helpful mineral that’s known to reduce tooth decay and improve overall dental health
  • Water purification systems need to be maintain on a regular basis, which is meant to ensure that contaminants don’t increase on older filters
  • It’s possible that the purification process won’t get rid of certain contaminants, which can include some chemicals and pesticides
  • Purchasing purified bottle water or selecting an in-home purification system can be costly, which is why you should weigh the pros and cons of drinking this form of water
  • If you choose to purchase plastic bottles of purified water, doing so causes a significant amount of waste, which is harmful to the environment

Purified vs. Filtered Water

If you’re thinking about drinking purified water, you should first know about the difference between filtered water and purified water. These two terms are typically used interchangeably but are actually somewhat different. Even though both types of water are filtered, purified water goes through additional purification processes, which can include everything from distillation to reverse osmosis.

Because of the additional processes for purified water, it comes in at a much higher purity than filtered water. When going through the purification process, at least 99.5 percent of all contaminants will be removed from the water, which is true regardless of the exact water source. With filtered water, the source of water dictates how much contaminants can be removed.

What is Distilled Water?

Distilled water is a kind of purified water that has been taken directly through the distillation process. This process is one of the methods that can be used to purify water. Distillation works by boiling water and collecting the steam that results, which will return to water once cooled.

This purification process has proven to be highly effective at getting rid of such contaminants as:

  • Many different viruses and bacteria
  • Certain protozoa like giardia
  • Various chemicals such as sulfate and lead

Because of how pure distilled water is, it’s commonly used in laboratories and medical facilities. While purified water is more commonly drunk than distilled water, it’s still possible to drink distilled water since it’s entirely free of impurities.

Health Benefits of Distilled Water

Drinking distilled water can be very beneficial to your health through such benefits as:

  • Water distillation is among the most effective ways to rid water of contaminants
  • Distilled water is free of contaminants like bacteria and pesticides, which can be beneficial for individuals who suffer from a weakened immune system
  • You may live in a location that doesn’t have particularly strict tap water regulations, which means that drinking distilled water would keep you healthier
  • Individuals who suffer from HIV or various types of cancer have a higher risk of becoming sick via impurities in water or food, which means that distilled water should be a better option than other types
  • Distilled water gets rid of chlorine from the water, which should enhance the taste of the water

While you shouldn’t solely drink distilled water, it’s highly recommended that you consider drinking distilled water every now and then because of the many health benefits that it provides. Before you do, however, you should know about the various issues that come with drinking distilled water.

Cons of Distilled Water

The issues of drinking distilled water include:

  • While the distillation process removes contaminants, it also gets rid of electrolytes and natural minerals that are essential for a person’s health
  • Healthy minerals like magnesium and calcium are removed completely from distilled water
  • Not getting enough magnesium and calcium in your diet places you at a higher risk of heart diseases, fractures, and preterm birth
  • Distilled water gets rid of fluoride, which can help prevent cavities

As long as you maintain a healthy and balanced diet, it should be safe for you to drink distilled water. Make sure that the healthy minerals and electrolytes that are removed from distilled water are consumed through some other facet of your diet.

Which Is Best: Purified Vs. Distilled Water?

Both purified and distilled water are very healthy for you and are essentially the same. The main difference between the two is that purified water doesn’t necessarily get rid of all of the healthy minerals that can be found in water, which isn’t the case with distilled water. It’s also important to understand that the process of distilling water consumes a significant amount of energy, which means that it’s somewhat harmful to the environment. If you use the reverse osmosis process, you’ll be using much less energy.

When you want the cleanest water that you can find, it’s recommended that you opt for distilled water. If, however, you want to drink clean water that’s somewhat healthier, you should choose purified water. Both types of water are healthy for you as long as you maintain a balanced diet. If you’ve been searching for ways to purify your drinking water, you can either distill your water or use the reverse osmosis process, the latter of which takes the water through a semi-permeable membrane. No matter which option you decide to use, you should be provided with clean and healthy water.

If you want to test the quality of the water to make sure that it’s purified, there are several Sensorex sensors that can help you measure water quality. For instance, the CS700 contacting conductivity sensor can help you determine how much impurities and contaminants are in your drinking water. You can also test the pH of the water with the pH1000 sensor to make sure that the levels are correct after you have purified the water. Readings between 6.5-8.5 indicate pure water.
