Water ionizers are an increasingly popular tool for helping to improve the quality of drinking water. As more and more people become aware of the potential health benefits that come with drinking ionized water, there is a growing interest in how these machines work. In this article, we will explain how a water ionizer works.

Key Takeaway
  • A water ionizer is a device designed to change water’s pH level.
  • Ionized water has a higher pH level, which has been shown to improve health.
  • However, an excessive amount of ionized water may cause health issues.


What is a Water Ionizer?

A water ionizer is a household appliance that transforms regular tap water into alkaline and acidic water through electrolysis. This appliance works by using electrodes separating the incoming water stream into two different streams: acidic and alkaline. The alkaline stream is used for drinking, while the acidic stream can be used for cleaning or disinfecting.

The main purpose of a water ionizer is to produce high-quality drinking water with numerous health benefits. Alkaline ionized water has been shown to neutralize the acid in the body, which can help prevent diseases such as cancer, osteoporosis, and diabetes. Additionally, this type of water contains antioxidants that have anti-aging properties. Here is a list of the best water ionizers that you can go through. 

What Does a Water Ionizer Do?

A water ionizer is a device designed to change water’s pH level. The process of ionization involves separating the alkaline and acidic components of the water, resulting in two separate streams.

One stream contains alkaline minerals such as calcium, potassium, and magnesium, while the other contains acidic minerals like sulfur and chlorine.

How Do Water Ionizers Work?

The process starts with tap water filtering through the device to remove impurities. Once cleaned, the water passes through an electrode chamber exposed to a low-voltage direct current. This electrical charge divides the H2O molecules into their constituent parts: positively charged ions (H+) and negatively charged ions (OH-). 

These ions then separate out into two different streams – alkaline and acidic – as they pass through separate chambers on either side of the electrode plates.

Benefits of Ionized Water

As people become more health conscious, more are turning to ionized water as an alternative to tap and bottled water. Here are some of the benefits of making ionized water at home:

  • For one, it is a powerful antioxidant that can help neutralize harmful free radicals in the body.
  • Additionally, it is believed that because of its smaller molecular size and altered electrical charge, ionized water may be easier for the body to absorb than regular water.
  • Another benefit of drinking ionized water is its alkaline pH level. Many experts believe maintaining an alkaline balance in the body can help fight inflammation and disease. Ionized water typically has a pH level between 7 and 9, which falls within the optimal range for good health.

In addition to these benefits, many people report experiencing increased energy levels and improved digestion after switching to ionized water.

Is Ionized Water Anti-aging?

Yes, ionized water is anti-aging in several ways.

Ionized water is alkaline and can help balance the body’s pH levels. This is important because when our bodies become too acidic, it can lead to inflammation, contributing to aging. Drinking ionized water regularly can reduce inflammation and support healthy aging processes.

An ionized machine uses an electrical charge to separate the water into two streams: acidic and alkaline. The alkaline stream is believed to contain antioxidants that could help neutralize free radicals in our bodies that contribute to aging.

Additionally, studies have shown that drinking alkaline water can improve hydration levels and potentially reduce inflammation, which are important factors for healthy skin.

What is the Difference Between Ionized Water and Distilled Water?

Understanding the difference between ionized water and distilled water can be confusing. Both types of water are purified, but they go through different processes to achieve their purity. Ionized water is also known as alkaline or electrolyzed reduced water, while distilled water is created through distillation. 

Ionized water is created by running tap or filtered water through a machine that uses electrolysis to separate it into acidic and alkaline components. The alkaline portion of the water has a higher pH level than regular tap or filtered water, which some people believe provides health benefits.

On the other hand, distilled water goes through a process where it is heated to a boiling point to create steam. The steam is then collected and condensed back into liquid form, leaving behind any impurities that were in the source.

What Makes Ionized Water Different From Tap Water?

The answer lies in the pH level and molecular structure of the water. Tap water typically has a neutral pH of around 7, while ionized water has a higher pH level between 8-9.5, making it more alkaline. 

This increased alkalinity is believed to have numerous health benefits, including improved hydration and detoxification abilities within the body. Additionally, ionized water is said to have antioxidant properties due to its negatively charged molecular structure. This allows for better absorption of nutrients and minerals by the body and potentially reduces inflammation. 

In contrast, tap water may contain harmful chemicals such as chlorine and fluoride, which can be detrimental to our health over time. Ionization filters out these impurities while adding beneficial minerals such as calcium and magnesium back into the water.

Is Ionized Water Healthier Than Distilled Water?

While both types of water have their benefits, there are some key differences between them. Distilled water has a neutral pH level, while ionized alkaline water typically has a higher pH level of around 8 or 9. The high pH level means ionized water is more likely to have a laxative effect than distilled water. The higher pH level can make our digestive system more alkaline.

However, you should not drink ionized water regularly; instead, use it as a detox method for your health.


Water ionizers are a great way to improve the quality of your drinking water. These ionizers utilize electrolysis technology to separate clean, alkaline water from acidic waste. You can enjoy greater health benefits from your ionized water by increasing the pH levels, adding antioxidants, and removing any harmful agents. Of course, you should always consult your doctor regarding the health benefits of drinking ionized water before changing your diet.
