Best 2023 Water Ionizer – Guide & Reviews

Water is an essential fluid in our lives and without it, we can die. That is why human beings have gone the extra mile to develop machines like water ionizers which changes the pH of the drinking water in accordance with your preferences.

Water Ionizer, also known as alkaline ionizer is a home appliance that raises the basicity of drinking water using electrolysis to separate incoming streams of water into acidic and building blocks.

Modern water ionizers have incorporated the current technology to an extent that you choose the level of the alkalinity of water you want just by a click of a button. You can choose, for example, weak alkaline, medium, firm or ultra-strong alkaline just by a press of a button.

Getting the best Ionizer in the market is tricky. You never know which one is certified and meet the required standards just by a look at them if you do not have knowledge about the ionizer.

How to Choose the Best Best Faucet Water Filter

There are some factors you need to consider before buying a water ionizer. The following five considerations are what some Ionizer companies do not want you to know. They include:

FDA Approved Plastics

Some water Ionizers in the market have fake plastics hoses. These plastics can release a harmful chemical to the water and when consumed may harm your body. It is, therefore, worth noting that before you buy any water Ionizer, check to see if it is FDA approved. That is the only way to know.

Tested Electronics

Some companies manufacturing water Ionizers do not take their products for testing. As a result, you end up buying Ionizer, which is electrically unsafe, has power supply inconsistency and less durable.

Always ensure that the Ionizer you buy is UL, CE or ETL certified. Note however that the ETL standardization is the best as all its products undergo 200 prescribed safety standards.

Water Source

It is nice to know your water source before buying a water ionizer. There are two types of water; hard and soft. The difference is the content of mineral salts. Soft water has low content while hard water has more mineral salts.

Most ionizers sold in the market work best with hard water, so if your source is soft water, then you will need to contact your supplier to modification for optimal performance.


Most Ionizer distributors overcharge consumers. You should be well versant in prices of water Ionizer before buying one. The best Ionizer in the market should not cost you more than $900.

To avoid such problems, you can save hundreds of dollars by buying water Ionizer directly online from Amazon because they will never charge you more than the actual price of the item.

Chemicals Used

Some of the water Ionizers use chemicals to change the pH of the water in the ionizer. Some of these chemicals are harmful to tour bodies. For example, Sodium Chloride, harmless enough and sodium hypochlorite which is toxic to our bodies. You can look at its properties on Wikipedia. You should question and be careful with some of the chemicals used to enhance the pH of the water.

Other Considerations

  • Inclusion of the latest technology in design
  • Ease of use
  • Self-cleaning mechanism of the ionizer
  • Ability to regulate incoming water pressure
  • Efficiency
  • The lifespan of your water ionizer

Recommended Best Water Ionizer

I have done enough research and from experience also, I decided to present to you some of the best water ionizers in the market. They are safe to use, pocket-friendly and very durable. They include:

1. Aqua-Ionizer Deluxe 7 Plate Alkaline Water Ionizer

Aqua-Ionizer Deluxe 7 Plate Alkaline Water Ionizer

Aqua-Ionizer Deluxe 7 Plate Alkaline Water Ionizer and Alkaline Water Machine is the first machine we want to talk about. It has excellent features, meets the standard of ETL certification, FDA approved and had the latest technology

Seven Healthy Water Options

There are seven water options you can get from this ionizer. You can either get ionized alkaline, ionized acidic or non-iodized purified water. The seven options are four ionized alkalines continuously variable; two ionized acidic presets; one non-ionized purified.

Advanced seven Electrode Technology

The technology in designing water ionizer does not require large electrode plates like the traditional ones where the size of the plate was a factor to consider. These seven electrodes are platinum-coated titanium which is durable and energy-efficient.

Built-in Carbon Water Filter

The built-in carbon water filter is very active. It is a long-lasting, high tech filter that purifies over 1,585 gallons of water before replacement.


This ionizer has a self-cleaning mechanism that produces clean water all the time. The unit cleans itself by reversing its polarity after each use. It also has an auto plate washing after every 10.5 gallons of water have passed through it.

Other Features

The range of pH is big enough to satisfy your thirst. It is between 4.5 and 11. Also, the OPR range is between+600 to -850mV. It has an intuitive backlit LCD and comes with a limited lifetime warranty.

3. NEW Alkaline Water Ionizer Machine with Filter IONtech IT-580

NEW Alkaline Water Ionizer Machine with Filter

Editor Rating:

The third ionizer under my reviews is the NEW Alkaline Water Ionizer Machine with Filter IONtech IT-580.


Records alkaline water production volume and automatically cleans when production reaches 50 liters. The chamber cleaning provides double protection: prolonging the service life of electrolysis plates and stabilizes the Oxidation-Reduction Potential (ORP) value of the electrolysis process.

Powerful transformer

The transformer changes the voltage and the supply power for the electrolysis chamber. The transformer changes alternating current (AC) to direct current (DC), changing the impedance and separating a circuit. It supplies 100% power to the electrolysis chamber for making the best ion water. It also increases the electrolysis power, so no need for many plates. The five plates work the same or even better than other brands with seven and nine plates.

pH Range

The pH range of this ionizer is 4.5 to11. Its Oxidation-Reduction Potential (ORP) value is -850mV maximum. The Platinum-titanium electrolysis plates enhance durability.
