How does alkaline water ionizer machine work?

Water has two ions such: dissolved carbon dioxide ions called bicarbonate and mineral ions.

Mineral ions are calcium and magnesium which is positively charged while dissolved carbon dioxide ions are negatively charged.

The alkaline water machine has two compartments anode and cathode side. Both sides are separated using semi-permeable ion-exchange membrane 

The water is siphoned near the cathode side increases the hydroxide levels making it have high PH levels while the water siphoned near the anode side increases the level of hydrogen making it acidic.

The PH levels of the anode side are 4-6 and cathode side 8-12.

Most promoters claim water with high PH levels has a variety of health benefits and is alternative health practices of the alkaline diet. Acidic water is used for household disinfecting.

What to consider when buying alkaline water machine

Difference between alkaline water and alkaline ionized water

Alkaline water means the water PH levels increased by adding minerals such as magnesium, potassium, and calcium. You make alkaline water by adding baking soda, using alkaline water pitcher, alkaline water bottle, and lemon.

Alkaline ionized water is water in which PH levels are increased using electrolysis. The Alkaline ionized water is produced by alkaline water ionizer and is water with a high concentration of hydrogen.

The water ionizer machine converts regular water into alkaline drinking water which is good for cooking, brewing coffee, removing tough stains and sterilizing.

It also converts the regular water into acidic which is good for cleaning water, brushing teeth, sunburn relief and sanitizing.

The Alkaline ionized water is water with a high concentration of hydrogen which is delicate. Hydrogen evaporates within 24 hours so you are required to consume water within 24 hours to get the beneficial effect of negative ions in the water.

Why do you need to buy an alkaline water ionizer?

Since Alkaline ionized water is water with a high concentration of hydrogen; the hydrogen evaporates fast within 24 hours so the ionized water cannot be sold in bottles and the machine is needed.

Does alkaline ionized water have health benefits?

Promoters claim ionized water has a variety of health benefits such as anti-aging, help in weight loss, natural detoxification, boost the immune system, and more but no proven medical evidence.

How do I choose an alkaline water machine?

  • Plates material

Water ionizers should have platinum-coated titanium plates that do not accept other ionizers that have other metals like gold or alloy coated.

Titanium can resist erosion and platinum has an efficiency of ionizing water.

A low voltage current is passed to the plate. When water molecules come to contact with charged plate it separates water into positively charged and negatively charged.

  • Number of plates

Another thing to check on plates is the number. The more the number of plates the more effective your ionizer will be.

Normally ionizer with more than 5 plates is better.

The unit with plates less than five is cheap but will provide poor water quality, limited functions, and a low flow rate.

The machine with more that five plates is expensive but will provide high quality water, more function, and a high flow rate.

  • Cleaning of plates

There are water ionizers that are designed to automatic self-clean after every use or after some time.

Other customers are required to program the unit to clean itself according to water source and usage.

The best ionizer is the one automatically self-clean without involving the user to program it.

  • PH and ORP levels

The main aim of ionizers is to increase the water PH level, provide alkaline water and water with reduced ORP.

Your machine should be able to provide all these different types of water.

  • Warranty 

The alkaline water machine is an expensive device so you need to buy from reputable companies and has a warranty.

Some brands have a lifetime warranty, others two to five years.

  • Product quality certification

The product should be certified by independent bodies such as Water Quality Association (WQA), NSF Certification, EPA and made of BPA free material

How do I choose an Alkaline water machine?

There are a number of things you need to check when buying alkaline water machine such as plates material, number of plates, cleaning mechanism, warranty, product quality certification, PH and ORP ranges.


How do machines make alkaline water?

The alkaline water machine uses electrolysis to separate incoming water from the tap or well into acidic or alkaline.

What do water ionizers do?


The water ionizer machine converts regular water into alkaline drinking water which is good for cooking, brewing coffee, removing tough stains and sterilizing
It also converts the regular water into acidic which is good for cleaning water, brushing teeth, sunburn relief and sanitizing.
The water ionizers have a filter that removes contaminants present in your tap water
