Best Water Ionizers {Updated September 2026}

What is Ionized Water?

Ionized water is water that contains minerals that have undergone an ionization process. The ionization process involves the separation of the acid and alkaline that is present in H2O. This is achieved through electrolysis. The electrolysis is done in consideration of the electric charge that is present in the magnesium and calcium ions. When water is ionized, it is then able to gain or lose an electron. When you ionize water for it to gain extra electrons, it is then able to assist in enhancing the ability of your blood to carry extra oxygen whenever you drink it. The ionized water is also able to cancel out any content that is bad in your bloodstream. When you ionize water for it to lose extra electrons, it is then not suitable for drinking. The water is then suitable for cleaning purposes.

Can All Water be Ionized?

Not all water is able to respond to the ionization process. This means that water that is distilled or water that has undergone reverse osmosis is water that cannot be ionized. This is due to the fact that water that is distilled or that has undergone reverse osmosis does not contain minerals. Ionized water contains minerals that have an electric charge.

Different types of Ionized Water

The ionized alkaline water is also called “Electrolyzed Reduced Water.” It reduces the effects of oxidation, which is an action in which an electron is taken away from something by an acidic substance. This action damages or destroys something. This is why an apple turns brown if it is cut. This is also why metal rusts. Ionized water reduces this effect because it has extra electrons in it which fight this process.

The ionized acidic water is called “Electrolyzed Oxidative Water” by scientists. Just by the name of this water, which is scientifically defined, we can tell it is the complete opposite of ionized water. This water increases the action of oxidation. This water is great for sanitizing anything. You can put this water in your swimming pool, in your hot tub, or in your washing machine. If you add some salt to ionized acidic water, it is an excellent alternative to other harsh chemicals in your home.

What Are the Benefits of Drinking Ionized Water?

There are many benefits of drinking ionized water. Here are just eleven of the benefits of drinking ionized water:

1. It has the ability to hydrate your body three to six times more than other types of water. This can be an extremely useful way of hydrating someone in an emergency.

2. It also increases your hydration of your skin. This can greatly help with many different kinds of skin problems. It can also help to put moisture back in your skin if it has suffered from sunburn. It can also help to put moisture back in your skin if it has become dry, itchy, and rough.

3. The advantages of ionized water are associated with the intake of various vitamins, e.g., vitamins A, C, and E. The ionized water contains oxygen that carries an additional electron, and this electron has numerous advantages. The additional electron will give your body a boost as it seeks out radicals that may make your body more susceptible to diseases. The additional electron will also help slow down the premature aging of your body. The additional electron may give your body the advantage of producing more energy and working at a higher rate every day.

4. It is also suggested by some researchers that the quality of the taste of food can also be improved with the use of ionized water. Ionized water is used by most of the commercial food-producing companies in the production of their food products.

5. Ionized water is also able to assist the body in the safe removal of acids that are trapped in the cells of the body. These cells, which contain acids, have the potential to cause common illnesses such as allergies, acne, colds, diabetes, indigestion, headaches, etc., if the acids are not removed from the cells.

6. It can also be used to help an individual in their weight loss journey. It is important to note that if there is a lack of alkaline in your body, your PH balance may be off. It is also important to note that your PH balance is one of the most important components of weight loss. Ionized water can provide you with the boost of alkaline that you may need in order to remove the acids that may be trapped in your fat cells, thus preventing you from losing weight. It can also be used to prevent the trapping of acids in your fat cells.

7. It also has the potential to assist in the removal of toxins that may have settled in the joints of the body, or those that have solidified into uric acid crystals. It can thus be used to help you if you have joint pain.

8. The alkaline antioxidants in ionized water have the capacity to protect people from more than 150 diseases, including heart disease, according to Alkalinewaterplus.com.

9. It is not only good for repairing skin cells, but it is also good for your hair.

10. It is also an excellent source of water to use in the natural sterilization of surfaces, making it good to use in cleaning.

11. Ionized water is also good to use in watering your plants and flowers. It is good in keeping them hydrated, which makes them fresh and healthy longer.

What Is the Difference Between Alkaline Ionized Water and Regular or Tap Water?

1. Alkaline water has the capacity to provide pH buffers that can totally eliminate toxins from the body. Tap water is not capable of doing that.

2. Alkaline water is also rich in natural healing antioxidants that have the capacity to fight loose radicals in the body that could cause different kinds of illness. It also has the capacity to reverse the damage that previous radicals could have done in the past. Tap water is not capable of doing that.

3. The alkaline in the water also has the capacity to filter the water and eliminate toxins in it.

How Does Water Become Ionized?

For the water to be ionized, the process of ionization has to be involved, and of course, one can buy their own water ionizer. Water ionizers are also called alkaline ionizers. This is a home appliance that increases the pH value of the water intended for consumption through the process of electrolysis, which splits the flow of water into two parts, the acidic and the alkaline. This process involves the water passing through different plates in the machine. This process creates two new streams of water, the acidic and the alkaline. The more plates the machine has, the more effective it is at increasing the pH value of the water. This box-shaped machine is usually connected to the water supply in the kitchen. This machine regulates the low voltage electrolysis in the tap water supply, which is great to have before using the water to cook or clean.

What to Look For When Choosing the Best Water Ionizer

It is always hard to buy something without knowing what to look for. There are many water ionizers in the market with different features, and it can be a bit confusing when it comes to choosing the best water ionizer for your needs. Here are some things to consider when buying your water ionizer.

1. Your Budget

This is the first thing to consider before purchasing your water ionizer. You should consider how much money you are willing to invest in your water ionizer. A water ionizer can cost anything from $450 to $3000 and beyond.

2. pH Range

Most people buy water ionizers because of their ability to make water with an alkaline pH. Therefore, it is imperative to buy an ionizer that can make an amount of alkaline water that will give us the desired pH. This will depend on why you are buying your water ionizer. You may want to buy it to make drinking water, and in this case, you may want an ionizer with an ability to make an extra amount of alkaline water in order to benefit from its health properties. You may also want to buy it to make water for surface sanitation, and in this case, you may want an ionizer with an ability to make little or no alkaline water. You may also want an ionizer with an ability to make both drinking water and water for surface sanitation, and in this case, it is advisable to buy an ionizer with an ability to make an extra amount of alkaline water.

3. The Number of Plates in a Unit

As mentioned above, the more plates there are in a water ionizer, the better. The plates are what make water ionization possible since that is where tap water is being converted from acidic water into alkaline water. Since tap water is being forced past each plate in order for it to be used for drinking, cooking, or cleaning, what the plate is made of is also significant. More affordable units usually have five plates. More expensive units usually have up to ten or eleven plates. Of course, more expensive units consume more power or energy.

4. The Different Levels of Oxidation Reduction

As mentioned prior, oxidation reduction is significant in water. If you plan on purchasing a water ionizer that will give you safe and healthy drinking water, then you should invest in a unit that is capable of producing water with low levels of oxidation. Remember that oxidation is what makes metals rust and fruit turn brown. Just think of what it could do to your body. If you plan on using your water ionizer for purposes other than drinking, then you should invest in a unit that is capable of producing water with high levels of oxidation.

5. Water Filters

Each of these units is equipped with a water filter, so you should consider this as you think about the price of your water ionizer or your budget. You should also consider which of the water ionizers you are looking at has the best water filter for your water supply. If you have high water pressure, your water ionizer needs to be equipped with a powerful water filter. You should also consider the life of your water filter. Some water filters can last 12 months, whereas others may need to be changed every three to six months.

6. Installation and Counter Top Unit Vs. Under Counter Unit

Some water ionizers can be installed underneath your counter, whereas some can be installed on top of your counter. When deciding which water ionizer to purchase, you should consider which water ionizer will work best for you in your home. For instance, if you have plenty of space on top of your counter, a counter top unit can work for you, whereas an under counter unit can work for you as well. It is at this point that you consider the installation of your water ionizer. When you decide to place your water ionizer underneath your counter, installation can be complex, whereas if you decide to place your water ionizer on top of your counter, installation is not complex, and in some cases, you don’t have to use any tools to install your water ionizer.

7. Warranty

Always make sure that your water ionizer comes with a warranty. You are making a huge investment in your health. It should be treated like any other home appliance that you buy, such as a refrigerator or a stove. You can get water ionizers with lifetime warranties just like some of the products that we have listed below.
