Deionized water is water that has had its ions removed, making it pure H2O. It is often used in industrial and laboratory settings because of its purity. However, deionized water also has several benefits for the home user. In this article, we will explore those benefits and how to choose the best water ionizer for your needs.

What Is Deionized Water and What Are Its Benefits?

Deionized water is simply water that has had its ions removed. This can be done using a process called ion exchange. Ion exchange is a type of water purification that uses electrically charged resin beads to attract and remove impurities from water. This leaves behind pure H2O.

Deionized water has several benefits over regular tap water. First, it does not contain any dissolved minerals, so it will not leave behind any spots or streaks when used to clean. This makes it ideal for use in households with hard water. Additionally, deionized water is less conductive than regular water, making it safer to use around electronics.

How Does a Water Ionizer Work?

A water ionizer is a type of appliance that can be used to produce deionized water. Water ionizers work by running water through a series of electrically charged resin beads. These beads attract and remove impurities from the water, leaving behind pure H2O.

Water ionizers typically have multiple settings that allow you to produce different types of water. For example, some models have a setting for producing drinking water and another for cleaning. Additionally, many water ionizers come with filters that can be used to remove impurities from your tap water before it is run through the ionizer.

What Types of Water Can Be Produced With a Water Ionizer?

With a water ionizer, you can produce two different types of water: deionized water and alkaline water. Deionized water is simply pure H2O that has had its ions removed. Alkaline water is water that has been treated with negatively charged ions. This process raises the pH of the water, making it more alkaline.

Alkaline water has several benefits over regular water. First, it is believed to be more hydrating than regular water. Additionally, alkaline water is thought to neutralize the acid in the body and improve overall health.

How to Choose the Best Water Ionizer for Your Needs?

When choosing a water ionizer, there are a few things to keep in mind. First, consider the type of water you want to produce. If you only need deionized water for occasional cleaning tasks, a less expensive model may be sufficient. However, if you want to produce alkaline water for drinking or cooking, you will need a more sophisticated model.

Additionally, consider the size of the unit and the filters that come with it. If you have a large home or family, you will need a unit that can produce enough water to meet your needs. Likewise, if you have hard water, you will need a unit that comes with filters to remove impurities from your tap water.

The Pros and Cons of Using a Water Ionizer

Now that you know more about water ionizers, let’s take a look at the pros and cons of using one.


  • Can produce pure, deionized water for cleaning or drinking
  • Some models can produce alkaline water
  • Ion exchange is a safe and effective way to purify water
  • Many models come with filters to remove impurities from tap water


  • Water ionizers can be expensive
  • Some models require frequent filter changes
  • Ion exchange removes minerals from water, which some people believe is unhealthy

As you can see, there are both pros and cons to using a water ionizer. Ultimately, the decision of whether or not to use one depends on your individual needs and preferences.

If you are looking for a way to produce pure, deionized water for cleaning or drinking, a water ionizer is a good option. However, if you are concerned about the removal of minerals from your water, you may want to consider another type of water purification system.
