What Is Ionized Water?

best water ionizerCategorically, this is the first question that comes up. In simplest terms, ionized water is the water that has been transferred through an ionizer machine. Expressly, water ionizer features titanium and platinum plates. These exchange some of the platinum and titanium ions with the water.

What is the result? The result is water whose pH level is more alkaline. At the same time, it’s worth noting that, through this process, the water is also purified.

We could refer to ionized water as artificially alkaline water. Moreover, ionized water is also referred to as electrolyzed reduced water. That’s because it is believed to diminish the harmful effect that oxidation has on the human body. Nevertheless, we’ll expand more on the specific benefits and risks of alkaline water later on in the article.

The Differences of Alkaline Water and Regular Water

The next question that follows is: what is the actual difference between plain drinking water and alkaline water? The difference lies in its components. For example, alkaline water is different due to its particular sweet taste. This is widely attributed to the difference in alkalinity level, which has to do with the levels of minerals such as calcium, magnesium, sodium, potassium, etc.

At the same time, in line with a study from the journal The Annals of Otology, Rhinology, and Laryngology, drinking water with a pH level of 8.8 can actually contribute to relieving the symptoms associated with acid reflux. The comparison has been made between bottled and alkaline water, and this is what the researchers found.

Expressly, normal tap water has a neutral pH level of seven. If we were to address this on a scale from 1 to 14. On the opposite side, ionized water has a significant mass of electrons that donate to electron-thieving active oxygen. In other words, we could refer to it as being live water. Researchers say that it has a similar atomic structure as the waters that originate from glacial streams.

What Are the Benefits of Drinking Ionized Water?

Considering that ionized water is artificially alkaline water, their benefits pretty much overlap. You can make alkaline water yourself or prefer a top-notch alkaline water brand. However, while many benefits associated with ionized water are speculated, there are still some aspects that are definitely convincing.

One of the most compelling benefits is that ionized water is characterized by antioxidant properties. Therefore, what you get is an abundance of hydrated minerals, with excellent antioxidant potential.
At the same time, ionized water is said to taste better than regular water. However, we guess that this is a matter of taste, as each has his/her own preferences in this view.

Meanwhile, it is believed that ionized water has great benefits for your skin. That’s also thanks to its antioxidant potential. Overall, ionized water is considered to maximize your immunity.

Is It Safe to Use Water Ionizers?

benefits of water ionizerUsually, even if some products have an overflowing number of benefits, there are still some potential drawbacks that could come in the way. Does this apply in the case of water ionizers? Yes, this applies to our scenario as well.

While there are many claims concerning the benefits of ionized water, some researchers and doctors indicate that the research supporting the positive claims isn’t convincing enough. Some say that, before the ionization process, the quality of the source water is fundamental, to ensure that the ionized water is truly beneficial.

This is why some recommend using reverse-osmosis. This way, you can be sure that the water is purified before you proceed with connecting an alkaline ionizer. Overall, though, it is safe to drink ionized or alkaline water. That’s because it includes natural minerals that your body can benefit from. Nonetheless, you should continually check the mineral levels inside the water, to ensure that what you’re drinking is good for you.

How Does a Water Ionizer Work?

water ionizer reviewsBefore investing in a water ionizer, it makes sense that you want to find out more about its operation process, right? If you were considering purchasing a water filter, then knowing a bit about the product range is highly advisable.

At first glance, the operating process of a water ionizer might seem difficult to grasp. Normally, the water ionizer is linked to the kitchen water supply. This way, before you use water for drinking, cooking, or cleaning, the unit will regulate the low voltage electrolysis on the tap water.

So, it’s as simple as this: the normal water gets inside the unit, and when it leaves the machine, it is ionized. Note that this type of unit doesn’t add anything to your water. What they do, though, is convert the bicarbonate minerals present in the tap water into hydrate materials. That’s because the latter are more alkaline. Therefore, they are easier to absorb by the body. This is actually what the process of electrodialysis entails.

When the water enters the ionizer, two separate streams of water come out. One of them is acidic and one of them is alkaline. Usually, it should be used for drinking and cooking, due to the benefits alkaline water offers. Basically, tap water encompasses a solution of magnesium bicarbonates and calcium. The water ionizer utilizes electromagnetically-charged plates to separate the magnesium and the calcium from the bicarbonates. Therefore, the mission of the ionizer is to pull them apart and redirecting two separate streams of water.

In order to understand the quality of your water easily, you can consider a reliable water test kit to use at home.

Water Ionizer Buying Guide

The thing with water ionizers is that they are complex machines, which are characterized by individual features. Therefore, what you may find in a specific product, you might not get with another one. For instance, when shopping for water filter pitchers or whole house water filters, the range of products on the market might throw you off. Leaving that aside, though, we believe that the following aspects should definitely be present on your list of priorities.

pH Range

Categorically, one of the main reasons why most people consider investing in such a unit is its capability of producing alkaline aka ionized water. This is connected to the unit’s capability of changing the water’s pH level. So, the pH level of the water clearly indicates the alkalinity or acidity level. If the pH level is 1 – then this would mean that we’re dealing with very acidic water. Meanwhile, if the pH level is 14, then this would make it very alkaline. 7 would be neutral.

As you’ve seen in our reviews, depending on the machine, some deliver quite a significant pH range, giving you flexibility and freedom in this respect. If you’re wondering why this even matters, hear us out. Each specific band is designated for particular utilization. For example, water whose pH level is low is suitable for cleaning and disinfecting.

On the other hand, mildly alkaline water is healthy for us to drink on a daily basis. On top of that, alkaline water is suitable for cooking. Of course, it’s entirely up to you if you need all these options. You should determine how you plan on using the machine and afterward make a decision accordingly.

Number of Plates

As you’ve read in the previous section on the way in which a water ionizer works, the plates of such a machine are of great importance. Why is that? That’s because the plates are where the water is converted from acidic to alkaline.

They come in direct contact with the water, which is why it is important to know the manufacturing material of the plates for instance. That’s because this is also likely to impact their efficacy level. Also, as a rule of thumb, the higher the number of plates a unit has, the better. That’s because this translates into more power. Basically, a unit equipped with more plates is capable of producing water whose pH range is larger, and whose ORP is much better (we’ll get right on to that).

Usually, the more affordable models come with 5 plates, whereas the pricier models incorporate 11 plates. However, it’s also worth noting that, if the unit has more plates, it will consume more power; not to mention that it will be pricier.

ORP Range

The ORP range stands for the oxidation-reduction potential. This refers to a water ionizer’s capability of oxidizing and diminishing the level of oxidation inside the body. Theoretically speaking, the lower the value of the ORP, the healthier the water it is for you to drink.

Oxidation is the natural process that turns an apple brown, for instance. At the same time, it is the process that determines rust to appear. This is facilitated by taking out electrons. The same happens inside the human body: oxidation damages the cells, the DNA, the proteins, so on and so forth. The substance that takes the electrons is known as a free radical.

This is where antioxidant foods come in. These aim at protecting the body from the effects of free radicals. The same principle applies to ionized water, which is believed to have the same effect, according to many researchers. That’s because the water restricts the free radicals’ capabilities of attacking your body, therefore, making it more vulnerable and susceptible to disease. To that end, it might be a good idea to choose a machine with a low ORP value. The lower the ORP value, the more capable the unit you’ll get.

Built-in Water Filter

Moving on, another thing that you should keep in mind during the shopping process is the built-in water filter. The majority of these symptoms come with this useful characteristic. For example, in the case in which you have a well water supply, it might be a good idea to choose a model whose filter is more powerful, so that it would easily cope with the water pressure without difficulty.

In this view, details such as price and lifespan come into the equation, as well. Note that you will have to replace the filter after a certain period. Therefore, this implies maintenance costs that should be taken into account at the time of the purchase. Normally, the lifespan of the filter ranges from six to twelve months, but this isn’t a general rule, as it depends on the manufacturer and how often you use the filter.

Installation Process

The installation process of a water ionizer is another consideration if you don’t want to be caught off guard when you try to install the machine and you don’t succeed. Nevertheless, the good news is that the installation process is usually easy and to the point. This applies, particularly, in the case of countertop units. In fact, in most cases, you won’t even need any tools or anything of the kind.

Nonetheless, things change a bit when it comes to under counter units. The installation process becomes a tad more time consuming and elaborate. But still, that doesn’t make it impossible; it simply means that it’ll take a bit more than a few minutes. You can have a look at this video, which shows the steps you should follow to install an under-counter water ionizer.

Counter Top vs. Under Counter Unit:

Another decision you’ll have to make is choosing between counter-top and under-counter units. This will depend mostly on the space you have at your disposal. If you have limited counter space, then it would make more sense to pick an under-counter unit than a counter-top one.


You might have noticed by reading this far that most water ionizers represent significant investments. That is to say, this isn’t a purchase you make every day. This is why the product you choose should come with a warranty. A generous warranty offers peace of mind, especially when acquiring something as important as a water ionizer.


1. How to install a water ionizer the right way?
We’ve already briefly talked about the installation process. There are several steps you should follow, in the case of under-counter units, in particular.

Firstly, you have to connect the machine directly to the waterline. In order to do that, you might need to uninstall the sink. But this isn’t necessary, depending on your kitchen. Afterward, it’s time to focus your attention on the faucet converter.

Of course, the next thing you do is actually connect the dots. In order to do that, the metal tube has to be attached to the unit. By using a screwdriver, you should position the elbow to the inlet of the ionizer’s unit. From that point onward, after connecting the hoses correctly, you can proceed with repositioning everything in its place.

2. How long does ionized water stay ionized?
Typically, the antioxidant properties of ionized water are prone to dissipate in roughly 18-24 hours. Meanwhile, the pH level is likely to drop in about three days. However, if you store it accordingly, alkaline water should preserve its initial properties for approximately a week.

Wrap Up

So, did you find the best water ionizer for you? We hope that most of the questions you had on the topic have been covered in our guide. Our aim was to make it as comprehensive as possible, which is why we included our water ionizer reviews, as well as a bunch of guidelines and recommendations for the shopping process.

One thing is for sure, while the benefits of ionized water are yet to be confirmed by subsequent evidence, there are still some convincing studies on the topic. At the same time, there isn’t any evidence pointing out that drinking ionized water could be potentially harmful. Therefore, considering this, investing in a water ionizer might be a sensible thing to do, especially if you’re concerned about your health, and you want to ensure that the water you drink is nutrient-full and safe.
