What Is Ionized Water?

Water is ionized when it passes through ionizing machines with titanium and platinum plates. Then there is an exchange of some platinum and titanium ions with water.

You get water with more alkaline pH and cleanness. It is also called ionized water or artificial alkaline water or electrolytic dehydration. This kind of water can reduce the harmful effects of oxidation on the human body.

You need to know that ionic water has two forms, it can be acidic or alkaline depending on its use in our bodies. Here they are:

  • Ionized Alkaline Water helps to decrease the harmful oxidation effects on the body. This water is ideal for both cooking and drinking.
  • Ionized Acidic Water increases the oxidation process, so it is especially useful for cleaning and disinfecting.

To better understand, people classify ionized water based on the water pH. Water with a pH above 7 is alkaline, a substance with a pH of 7 is neutral and below 7 is considered an acid. You can see the pH scale to know the pH of the water.

Alkaline Water VS. Regular Water

The difference between regular water and alkaline water is their components.

Alkaline water is different due to its unique sweetness and is related to the level of minerals contained in the water such as calcium, magnesium, sodium, potassium, and more.

According to research from the journal ‘The Annals of Otology, Rhinology, and Laryngology’, drinking water with a pH of 8.8 can contribute to reducing acid-related symptoms with a comparison made between alkaline water and bottled water.

As you know, regular tap water has a neutral seven pH according to a pH scale of 1 to 14 while ionized water has a significant amount of electrons for active oxygen to form “living water.”

Researchers believe it has an atomic structure similar to water from glacial streams. Alkaline water with a pH of 8 to 9 increases the level of alkalinity in the body and reduces the acidity associated with unhealthy eating habits and lifestyles.

Moreover, it excels in hydration because your cells quickly absorb it thanks to clusters smaller than ordinary water.

The Benefits Of Drinking Ionized Water

Many benefits related to ionized water are speculated, but there are still some persuasive aspects from scientific studies. The following are the benefits you get from ionized water:

  • The first is the antioxidant properties. You will get a lot of hydrated minerals that bring great antioxidant potential to your body. Antioxidants can help to decrease the harmful effects of free radicals on DNA and body tissue.
  • You can feel ionized water tastes better than regular water. However, note that the taste of water depends on one’s preferences.
  • Thirdly, your skin also benefits from this kind of water due to its antioxidant potential. And ionized water can maximize your immunity to make your body healthier.

Also, some of these studies are in the early stages of alkaline water, suggesting that it helps hydrate your body more effectively, improve digestion and reduce indigestion, and soothe acid reflux by killing pepsin and neutralizing the acid in your blood to increase oxygen, improve metabolism and increase energy.

In short, drinking ionized water does not have any adverse effects on your body, so it is safe to use.

How Does A Water Ionizer Work?

Knowing the process of ionizing water is necessary. This process is quite simple:
At first, the water ionizers are linked to kitchen water to regulate low voltage electrolysis on tap water before you use it for cooking and drinking.

Normal water enters the device, and when it leaves, it gets ionized without adding anything to your water. It only converts bicarbonate minerals in tap water into hydrate materials to increase alkalinity for better absorption of the body.

Because tap water includes a magnesium and calcium bicarbonate solution, water ionizers work by using electromagnetic charge plates to separate magnesium and calcium from bicarbonate and divert two separate water streams. You can imagine a stream of water entering the water ionizers, then two separate streams of water flow out including acidity and alkalinity.

As a result, the water is ionized to use for drinking and cooking due to the benefits of alkaline water or cleaning well thanks to the acidic water.

Depending on your family’s needs, you use the right kind of ionized water. That’s all for the operation of a water ionizer. Now we want to give you the buying guide for this product.

Important Factors to Consider When Looking For The Best Water Ionizer

There are many different features of a water ionizer. You can find these features in a specific product, but you may not have them in another one.

However, the seven following factors are necessary to consider when buying this product. Check them out.

a) The pH Range

The ability to produce alkaline water or ionized water is associated with changing the pH level of the water unit. As you know, the pH of the water indicates the degree of alkalinity or acidity.

Some water ionizers offer a wide range of pH for flexibility and freedom of use. You need to choose a device that produces water with a suitable pH range depending on the intended needs of your family.

For example, low pH water is ideal for cleaning and disinfection while mild alkaline water is good for health to drink and cook daily. It entirely depends on you if you need all these pH options.

b) Number Of Plates

The machine works well thanks to the number of plates converting water from acid to alkaline, and you need to pay attention to these critical parts when buying water ionizers.

The plates contact with water directly, so you should at least know their materials to ensure their effective operation. The higher the number of plates, the better the conversion is.

The device equipped with more panels can produce water with a broader pH range and much better ORP. You can find in the market, affordable models with five plates or more expensive models with 11 plates.

With multi-plate products, you can know that they consume more energy, but sometimes the price may not be high. Here are some kinds of plates for you to choose from:

  • GRID has the best quality, high efficiency, and durability.
  • MESH has high efficiency with excellent quality.
  • FLAT has good durability and quality.
  • Slotted has low quality among all types.
c) ORP Range (ORP: Oxidation-Reduction Potential)

The ORP range is the ability to oxidize ionized water and reduce the level of oxidation inside the body. The trick is that the lower the ORP value is, the better the water you drink is for your health.

Oxidation is a natural process such as turning to apple brown or rust appearing by taking electrons out. In the human body, oxidation damages cells, DNA, proteins, and more.

Free radicals take away electrons. The antioxidant process protects the body from the effects of free radicals. The same principle applies to ionized water because it limits free radicals from attacking your body so that the body is not damaged and ill easily.

d) Built-In Water Filter

In the above sections, we have mentioned water ionizers depending on the quality of the water supply, so you need to consider the product with an integrated water filter or buy and use it with a separate water filter device when required.

You can imagine this: When you have well water with some harmful substances, you have to buy a model with stronger filters before using a water ionizer.

Note that the lifespan of the filters is short when you have to replace them for about six to twelve months depending on the manufacturer and the frequency of use.

Installation Process

Water ionizers are usually easy to install. You just need to be aware that the countertop units have a quick installation without complicated tools and skills.

On the other hand, you have to spend more time on under-counter units. Typically, it will take you a few minutes to study and do the installation steps for this product.

Counter Top vs. Under Counter Unit

Which product type you choose depends on your needs and place to install.

We recommend that for small counter space, you should select an under-counter unit that is more appropriate than a counter-top one. And remember to select a device with a design that fits the general aesthetic overview of your kitchen.


You have to spend a considerable amount of money on this type of product, so you also need an extended warranty to use the water ionizer safely without worrying about damage and repair costs.

The great thing is that you often have a lifetime warranty for ionizing water products from many brands on the market. It helps you feel secure when using the product for a long time.

To sum up, you should consider all the relevant factors and choose the best water ionizer for your family’s needs.


Is It Safe To Use Water Ionizers?

Yes, it is. The ionized water has natural minerals for your body.

However, some researchers point out that research supporting the benefits of ionized water is not convincing enough. To ensure that ionized water is truly beneficial, the source of water quality is an essential thing to consider.

A tip for you is to use reverse osmosis to filter the water before connecting a water ionizer. And you should continually check mineral concentrations in the water to make sure what you drink is good.

How Long Does Ionized Water Stay Ionized?

The antioxidant properties of ionized water will disappear in 18-24 hours, and the pH level will decrease in about three days. If you store this kind of water appropriately, you can preserve its original properties for a week.
