How Does A Water Ionizer Work?

Before you buy a machine, you are always searching for how it works, the number of steps involved in the process, and how long does this ionized water stay ionized, right?

To understand how a water ionizer works, one needs to understand what goes behind the filtration process. The water ionizer involves a two-way process to produce both alkaline and acidic water.

The first step involves filtering out and removing all the harmful pollutants from the water, including chlorine, fluoride, phenols, odor, organic waste, bacteria, and sediments. The result is achieved through the deep filtration technology, while some ionizers contain activated carbon filters that tend to remove the contaminants more efficiently.

The second step entails the process of electrolysis, where an electric charge is set in motion into the water through platinum-coated titanium electrodes. The process takes place in a patent chamber that separates water into two streams of ionized water.

The positively charged ions gather around the negative electrode that concentrates alkaline minerals, potassium, magnesium, and calcium and creates reduced water. This alkaline water is used for drinking and cooking purposes.

Furthermore, the negatively charged ions gather around the positive electrode to make oxidized water, which compresses acidic minerals, for instance, sulfides, nitrates, chlorides from the tap water source. This oxidized water is used for a myriad of external purposes.

Additionally, the range of pH level is customizable and visible on the display of the ionizer water machine. The electrodes are later cleaned in an automatic cleaning cycle.

When you talk about the longevity of ionized water, the antioxidant will last for about 18-24 hours, while the water with a higher pH lasts for about 1-2 weeks.

What Are The Benefits Of Alkaline Water?

The numerous benefits of alkaline water are not present and accessible in the regular water. These include:

Radiant Skin

Skin appears to be more hydrated, while the ionizers help to flush out toxins to offer a clear and healthy complexion. There is also an improved acid balance in your blood as they improve the oxygen delivery in your body.

Promotes Weight Loss

Alkaline waters help in neutralizing and releasing acidic waste from your body that has been accumulated due to processed food. Therefore, the benefits of alkaline water include reducing fat and promoting weight-loss.

Healthy Bone Structure

With the abundance of calcium and mineral ions, collectively known as mineral hydrates, are sought to be the source of nutrition for our body.

Reduce Acid Reflux

People, who suffer from acid reflux symptoms such as nausea or heartburn, are advised to intake alkaline water of pH 8.8 to soothe the acid refluxes.

Promotes Anti-ageing Properties

The alkaline water is power-packed with antioxidants that fight with the free radicals that are the main source of accelerating aging properties in our body.

What Are The Factors To Consider When Buying Water Ionizer?

You might feel a bit overwhelmed while looking for the best water ionizer, as there are different water ionizers with different characteristics and functions. Therefore, this guide offers you the best possible factors to help you find the best ionizer machine based on your personal preferences.

Here, take a look at the key factor to narrow down your search for the best water ionizer machine:

Under-the-Counter or Countertop

The amount of space you have in your kitchen will determine the kind of ionizer that would fit comfortably in your kitchen. Both the units are made small and compact, keeping in mind to take as minimal space as possible.

Longevity of Filter

Most of the ionizers come with a built-in filter to remove any sort of contaminants present in the water.

Before you make a purchase, in case the filter needs to be replaced after every few months, make sure to review the total lifespan of the filter. Some filters last for a year while others for around six months. It also affects your cost, so be careful while you make a decision based on this factor.

pH And ORP Range

Most of the time, the decision is solely based on the pH and ORP levels of a water ionizer. In some ionizers, you are given full control to customize the pH level that suits you. Water with higher pH has more alkalinity and used for drinking and cooking. Also, don’t forget the health benefits.

In case you are wondering how to make alkaline water at home, or is it possible?

Then yes, baking soda and lemon have a pH level of 9 and 7, respectively, you may know how to make alkaline water as per your taste. But, it must be preceded by precaution as access to everything is harmful to our health. Therefore, an alkaline water machine is the best choice where you can control the pH levels.

ORP is better known as oxidation-reduction potential that determines the capability of water oxidizer in reducing the level of oxidation within your body. The lower the level of ORP, the healthier the alkaline water produced in the ionizer.

Offers Easy Installation Guide

You will be relieved to know that the water ionizer is easy to install, particularly the countertops. They are usually assembled in the first place where you won’t need any extra tools to install and fit them.

Nevertheless, the installation for under-counter ionizers is quite complex but not impossible. The water ionizer amazon provides a DVD in the package and a step by step guide for easy installation.


On average, the price for the standard water ionizer machine ranges from $600 to $2500. Some may fall beyond the price range due to its demand and brand value.

From here, you can determine what type of ionizer you want for your home that fits your budget comfortably.
