What is a water ionizer? Water ionizers are an innovative, natural way to improve your drinking water’s taste, odor, and even health benefits of your drinking water. They are an economical and environment-friendly way to get great-tasting, healthy water. 

With the simple push of a button, tap water transforms into a powerful source of health and wellness.

A water ionizer is a device that takes regular tap water and transforms it into alkaline, ionized water. This type of water has many health benefits, including improved hydration and digestion. In addition to its health benefits, water ionizers can improve the taste and smell of water, making it more pleasant to drink. In this article, you’ll explore what is a Water Ionizer.

What Is A Water Ionizer: How Does Water Ionizer Work?


A water ionizer consists of simple processes. Here are three steps on what is a water ionizer & how a water ionizer works: 

Step 1. Water travels through an internal water filter

The water from your faucet is funneled into the “In” pipe at the rear of the water ionizer. After it goes inside, the integrated water filter will remove as many pollutants as possible.

The life expectancy of the filter is approximately one year, and it comes with a hefty price tag of around £40/$50.

A water ionizer does not strive to create water entirely free of impurities; it needs some degree of contamination to operate at its best.

Step 2. During electrolysis, the water ionizer passes the water through electrodes with different charges, one positive and the other negative.

After traveling through the ionizer, the water flows over the plates, which are an integral part of this highly ingenious device.

When the water flows into an area with a specific, low-strength electric current, the soluble minerals, heavy metals, and other contaminants in the water go to either the positive or negative pole depending on the charge of their electrical energy makeup.

When this process takes place, it will divide the water into alkaline and acidic streams. You should drink the water from the alkaline water ionizer, while the acidic water is for external purposes, such as for skincare, plants, and as a disinfectant.

Step 3. Ionization of electrodes divides water into negative and positive ions, thus generating alkaline and acidic water.

The water gets divided into H+ (acidic) and OH- (alkaline). The electrolysis process is accountable for the substantial amount of antioxidants in alkaline water and for reducing the size of water molecules.

To keep it short and simple:

  • The water is treated to improve its smell and flavor.
  • The ionizer divides the water into two parts.
  • The end product of the process will be either water which is highly alkaline, or which is highly acidic.

Now, you know what is a water ionizer. So, let’s look at the benefits of a water ionizer.

What Is A Water Ionizer: Benefits Of A Water Ionizer


Here are some benefits of a water ionizer

Antioxidant-Rich Water

Water charged with ions has an incredibly high concentration of antioxidants! Even though pH is extremely vital, the antioxidant benefit is astonishing.

Technologies like Reverse Osmosis purify up to 90% of water & offer an alkaline post-filter to improve the flavor of the water. When water is put through a water ionizer, it obtains a slight electric charge, thus becoming electrolyzed.

As a result, the alkaline water generated by the ionizer has antioxidant properties, while the acid water is an oxidant. The antioxidant level in liquids is usually measured by a test known as oxidation-reduction potential or ORP. An ionizer’s output may range between -50 and -350 and above.

It is essential to consider that the more negative the result is, the more advantageous it is (up to the extent of -350, where the benefit does not rise any further). The pH and ORP of the water have almost no effect since our digestive system is already highly acidic. The essential minerals and antioxidants come from the high-quality food we eat.

Here are some of the average ORP scores: 

  • bottled water +350
  • distilled water +200
  • tap water +300
  • reverse osmosis water +200
  • soda +400

And on the practical side: 

  • juice (cranberry) -120
  • juice (orange) -50
  • alkaline ionized water -350
  • tea (green) -180

The data from these average readings indicate that ionized water provides a higher level of antioxidants than other popular drinks that are often praised for having antioxidant properties.

Each glass of water could give you a massive influx of antioxidants. Imagine how great you will feel in no time!

Perfect pH Between 7-8

It’s no secret that an alkaline diet is essential, so ensure that your drinking water has a pH level of 7-8, which is alkaline. If you have a water ionizer or a high-quality reverse osmosis system, you can achieve a pH range of 7-8.

pH From pH 3 To pH 12

You get pH 9.5 with an alkaline water ionizer. However, since the water ionizer works by dividing the water’s H+ and OH- ions, select the pH you want to receive (from as low as pH 3 to as high as pH 12).

There are several ways that low and high-pH water can be used, but only a small number of people will make use of any of them: 

  • Makeup remover (pH 4-5)
  • Antiseptic and antibacterial mouthwash (pH 3-4)
  • Cleanser and exfoliator
  • Adds extra antioxidants to fruits and vegetables (pH 11+)
  • Completely antibacterial (chemical free) cleaner for your household (ph 3-4)
  • Hand sanitizer (pH 3-4)
  • It can be applied to acne, psoriasis, and eczema (pH 3-4)
  • Remove pet smells (pH 4-5)

Filtered Water

A huge factor to consider when choosing a water system is the capacity of the ionizer.

If you attempt to reduce the acidity of water by using cost-effective methods like introducing salts, lemons, or minerals, you are overlooking the need for filtration.

There is no denying that tap water is not up to an acceptable quality standard, making it a potential health risk. Moreover, water ionizers are not capable of making the water pure.

Now, you know what is a water ionizer, how it works, and its benefits. So, let us look at its shortcomings.

What Is A Water Ionizer: Shortcomings

Recently, some firms have started selling water ionizers on the internet. They assert that their machines can create unpolluted alkaline water, which can avert sickness.

However, allegations of this kind are not supported by scientific proof and are not reasonable compared to the accepted principles of chemistry and physics. There are a few significant downsides to buying a water ionizer.

Function In Question

Water molecules can break up to form a hydroxide ion (-OH) and a hydronium ion (H30+). Conversely, the hydronium and hydroxide ions can recombine to generate water molecules again. The reaction balance favors the reactants, which is why the opposite reaction occurs quickly.

An acidic pH solution has higher hydronium ions than hydroxide ions. A solution with an alkaline pH has more hydroxide ions and a lower concentration of hydronium ions.

The electrolysis process does not change the pH of pure water so that it will remain neutral. This means that water ionization machines are unlikely to achieve the effects promised by their manufacturers.

Effect On Health

Despite the assertion that water ionizers can generate ultra-clean alkaline water, it is still uncertain whether it impacts a person’s well-being.

The acidity level of human blood stays around 7.4, and drinking alkaline water would not be capable of altering this balance, nor would it be desirable to try and change the pH of the blood.

Possible Harms

An effective way of achieving electrolysis is by adding salt to the water, making it more alkaline. When current is supplied, the two electrodes interact to produce hydrogen, hypochlorous acid, and sodium hydroxide.

The combination of substances would react and produce sodium hypochlorite, also known as Chlorine, a common ingredient in laundry bleach. Using a water ionizer in this manner can be hazardous because consuming a solution of sodium hypochlorite (or bleach) in low concentrations can be detrimental to one’s health.


A large number of water ionizers are expensive. The cost of such devices is exceptionally high because there is little chance they will work as promised since the term “pure alkaline water” has no scientific validity according to the current laws of chemistry and physics.

Summary: What Is A Water Ionizer


What is a water ionizer? A water ionizer is a machine that employs electrolysis to modify water composition at a molecular level. In succession, this procedure yields both antioxidant-rich ionized alkaline and oxidizing ionized acidic water.

A water ionizer starts by running the tap water through a filter composed of charcoal and other particle sizes, depending on the filter’s design.

Depending on the type of filter being utilized and the water quality required, ionizer filters cannot eliminate the majority of pollutants like chemicals and other contaminants in today’s world.

Unlike distillers or reverse osmosis systems, water ionizers do not eliminate soluble minerals, thus not delivering the purest water obtainable. The Environmental Protection Agency (EPA) advises that the ideal drinking water should have a Total Dissolved Solids (TDS) level between 0-50, which is not achievable with a water ionizer.
