What is ionized water?

Categorically, this is the first question that arises. To put it simply is ionized water the tap water that has been passed through an ionization machine. Titanium and platinum plates are used in a water ionizer. These release some of the platinum and titanium ions into the water.

What is the result? The result is water, its pH value rather alkaline is. At the same time, it is worth noting that the water goes through this process too cleaned becomes.

We could call ionized water artificially alkaline water. In addition, ionized water is also called electrolyzed reduced water designated. This is because it is believed to decrease the harmful effects of oxidation on the human body.

Nonetheless, we will address the specific health issues later in this article Benefits of ionized water elaborate.

Difference between alkaline water and normal water

The next question that follows is, what is the real difference between drinking plain water and drinking ionized water?

The difference lies in its components. For example, alkaline water differs in its particular sweet taste. This is largely attributed to the difference in alkali levels related to the levels of minerals such as calcium, magnesium, sodium, potassium, etc.

At the same time, according to a study by The Annals of Otology, Rhinology, and Laryngology, drinking water with a pH of 8.8 can actually be used Reflux Disease Relief (Heartburn) related symptoms. In this study, a comparison was made between bottled water and alkaline water (1).

More specifically, normal tap water has a neutral pH - seven - if we look at this on a scale from 1 to 14. On the opposite side, ionized water has a significant mass of electrons that give off the electron-withdrawing active oxygen.

In other words, we could call it living water describe. Researchers say it has an atomic structure similar to the water that is made up of it Glacial streams originates.

How does a water ionizer work?

Before you get into a Buy a water ionizer, it makes sense that you want to know more about its operational process, doesn't it? If you are considering purchasing a water filter then it is very advisable to do a little about that functionality of a water ionizer device.

At first glance, how a water ionizer works may be difficult to grasp. Usually the water ionizer is attached to the Water supply in the kitchen connected. In this way the device controls the Low voltage electrolysis tap water before using it for drinking, cooking, or cleaning.

So it's very simple: Normal tap water enters the device and when it leaves the device it is ionized. Note that this type of device will not add anything to your water. What they do, however, is convert the bicarbonate minerals present in tap water into Hydrate materials. That's because the latter are more alkaline.

The water from a water ionizer can be more easily absorbed by the body. This is basically exactly what the electrodialysis process entails and why ionized water is so healthy.

When the water enters the ionizer, two separate streams of water come out. One of them is acidic and the other is alkaline. Usually it should be used for drinking and cooking as alkaline water offers some benefits. Basically, tap water contains a solution of magnesium bicarbonates and calcium.

The water ionizer used electromagnetically charged platesto separate the magnesium and calcium from the bicarbonates. Hence, the job of the ionizer is to pull them apart and divert two separate streams of water.

Buying guide for water ionizers

The thing about water ionizers is that they are complex machines that have individual characteristics. As a result, you may not get what you find in one product in another.

For example, if you want to compare and buy water filter jugs or tap water filters, you may be put off by the large supply on the market. That being said, however, we believe that the following should definitely be on your list of priorities if you are looking for a device to ionize your tap water at home.

Looking for the best water ionizer? Keep these important factors in mind

  • pH range:
    One of the main reasons most people consider buying into a water ionizer is its ability to produce alkaline also known as ionized water. This is related to the way the device works to change the pH of the water.
    The pH value of the water indicates the alkalinity or the degree of acidity. If the pH is 1 - then it would mean that we are dealing with very acidic water. If the pH is 14, it would be very alkaline. 7 would be neutral.
    As you have seen in our reviews, some devices provide quite a significant and adjustable pH range, which gives you flexibility and freedom in this regard.
    If you're wondering why that matters in the first place, here's a quick explanation: Each specific spectrum is designed for a specific application. For example, water with a low pH value is suitable for cleaning and disinfecting. Weakly alkaline water, on the other hand, is healthy for us to drink daily. In addition, alkaline water is very suitable for cooking.
    Of course, whether you need all of these options is entirely up to you. You should determine how you want to use the device and then make an appropriate decision.
  • Number of plates:
    As you read in the previous section about how a water ionizer works, the plates of such a device are of great importance. Why is that? Because the plates are the place where the water is converted from acidic to alkaline.
    They come into direct contact with the water, which is why it is important to know, for example, the material used to make the panels. Because that should also affect their effectiveness.
    Another rule of thumb is: the more disks there are in a device, the better. Because that means more performance. In principle, a water ionizer equipped with more plates is able to produce water whose pH range is larger and whose redox number is much better (we'll talk about this in a moment).
    Usually the cheaper models come with 5 plates, while the more expensive models come with 11 plates. However, it's also worth noting that a device with more disks uses more energy when it has more disks; not to mention that it is more expensive.
  • ORP area:
    The ORP area stands for the oxidation-reduction potential. This refers to the ability of a water ionizer to oxidize and reduce the level of oxidation inside the body. In theory, the lower the ORP, the healthier the water you drink.
    Oxidation is the natural process that, for example, turns an apple brown. At the same time, it is also the process that determines the appearance of rust. This is made easier by the removal of electrons. The same thing happens in the human body: the oxidation damages the cells, DNA, proteins and so on and so forth. The substance that withdraws the electrons is called a free radical.
    This is where antioxidant foods come into play, which are supposed to protect the body from the effects of free radicals. The same principle applies to ionized water, which many researchers believe to have the same effect. This is because water limits the ability of free radicals to attack your body, making it more vulnerable and susceptible to disease.
    To do this, it might be a good idea to choose a device with a low ORP.The lower the ORP, the more powerful the device will be.
  • Built-in water filter:
    Another point to consider before buying a water ionizer is the built-in water filter. Most devices are equipped with a useful water filter that cleans the water at the same time.
    For example, if you live in an area that has poor water treatment, it might be a good idea to choose a model that has a more powerful filter so that it can withstand the water pressure without difficulty.
    With this consideration, details such as price and lifespan also come into the equation. Note that you will have to replace the filter after a certain period of time. This therefore implies maintenance costs that should be considered at the time of purchase. Typically, the life of the filter is between six and twelve months, but this is not a general rule as it will depend on the manufacturer and how often the filter is used.
  • Installation process:
    The process of installing a water ionizer is another consideration if you don't want to be surprised when you try to install the device and fail.
    The good news, however, is that the installation process and getting started is usually straightforward. This is especially true for water ionizers on the kitchen countertop. In fact, in most cases, you don't even need tools or anything.
    Still, things change a bit when it comes to water ionizers that need to be built in under the sink. The installation process will be a bit more time consuming. But that doesn't make it impossible anyway; it just means that it will take a little more than a few minutes. You can watch videos from the manufacturer on YouTube showing the steps you should follow to install an under counter water ionizer.
  • Set-up device vs. under-table devices:
    Another decision you will need to make is the choice between a stand-alone unit and an under-table unit. This mainly depends on the space you have available. If you have limited space on the kitchen countertop, it would make more sense to choose a water ionizer under the sink than a water ionizer that is placed on the countertop.
  • The warranty:
    If you've read this far, you may have noticed that most water ionizers are significant investments. This means that this is not an acquisition that you make every day. For this reason, the product you choose should come with a guarantee. A generous guarantee gives you peace of mind, especially when you buy something as important as a water ionizer.

Are Water Ionizers Safe and Healthy?

Even if water ionizers a variety of health benefits usually there are still some potential downsides that could get in their way. Does this also apply to the best water ionizers? Yes, this also applies in our scenario.

While there are many claims about that Benefits of ionized water, but some researchers and doctors state that the research backing the positive claims is not convincing enough. Some say that prior to the ionization process, the quality of the spring water is fundamental to ensure that the ionized water is really beneficial.

For this reason we recommend using a Reverse osmosis system. This way you can be sure that the water has been purified before proceeding with the connection of an alkaline ionizer.

Overall, however, it is safe, ionized or drinking alkaline water. That's because it contains natural minerals that your body can benefit from.

That said, you should keep checking the mineral levels in the water to make sure that what you are drinking is healthy and good for you.

What are the benefits of ionized tap water?

When you consider that ionized water is artificially alkaline water, their benefits overlap quite a bit. However, while the benefits associated with ionized water have been speculated, there are still some aspects that are definitely compelling.

One of the most compelling advantages is that water is ionized through it antioxidant properties excels. Hence, you get an abundance of hydrated minerals with excellent antioxidant potential.

At the same time, ionized water is said to be tastes better than normal water. However, we suspect this is a matter of taste as everyone has their own preferences in this regard.

It is now believed that ionized water is great Benefits for your skin Has. This is also thanks to its antioxidant potential. Overall, ionized water is also assumed to be yours Strengthens the immune system.


  • Question: How do you properly install a water ionizer?
    We've already talked briefly about the installation process. There are several steps you should follow, especially in the case of water ionizers that are placed under the sink in the kitchen.
    First, you need to connect the device directly to the water pipe. You may have to turn off the water supply to do this. Depending on the type of kitchen you have, this may not be necessary.
    After that, it's time to turn your attention to the faucet converter. Next, of course, you need to connect the device to the cold water supply.
    To do this, the metal pipe must be attached to the unit. Using the appropriate tool, you should position the contra-angle at the inlet of the ionizing unit. From this point on, once you've connected the hoses correctly, you can put everything back into place.
  • Question: How long does ionized water stay ionized?
    The antioxidant properties of ionized water usually dissipate after about 18-24 hours. In the meantime, the pH will likely drop over a period of three days. However, if you store it appropriately, alkaline water should retain its original properties for about a week. To reap the potential health benefits, we recommend always drinking the alkaline water straight from the tap.

Also take a look at our comparison of the best water test kits for home and use it to regularly check whether your tap water is contaminated or not.


So have you found the best water ionizer for you? We hope most of the questions you had about this topic have been covered in our guide.

Our goal was to make it as comprehensive as possible, which is why we've included our reviews of the best water ionizers, as well as a number of guidelines and recommendations for the purchasing process.

One thing is certain, even if the benefits of ionized water have not yet been confirmed by post-evidence, there are still some compelling studies on the subject. At the same time there is no Evidence suggesting drinking ionized water could be potentially harmful.

With this in mind, investing in a water ionizer could therefore be a wise thing to do, especially if you are concerned about your health and want to make sure that the water you drink is nutrient-rich, antioxidant, and safe.
