The Most Unique and Important Features About a Water Ionizer Machine

  • Ionized water is the right pH to help rid the body of toxins.
  • Water ionizers filter the water far better than bottled water.
  • Ionized water contains a natural and strong antioxidant called molecular hydrogen. Molecular hydrogen bonds more easily with free-radicals to neutralize them than any other antioxidant: The Healing Ability of Molecular Hydrogen
  • All water has hydrogen of course (H2O), but only water with molecular hydrogen in it can act as an antioxidant.
  • Water ionizers have been tried and proven for over 30 years. My husband and I have been drinking ionized water for 25 years. It has been a life-changer for us. See my testimonial.
  • Water ionizer Machines are important, and the benefits of alkaline water machines have been proven. So, if you're not fully familiar with the hundreds of benefits, we encourage you to read these pages: BenefitsResearchSuccessesStudies, and What Doctors Say

Water Ionizer Comparisons


AlkalineWaterPlus Offers the Best Water Ionizer Systems

What is the Best Water Ionizer? The best water ionizers are the ones that can produce the highest levels of molecular hydrogen antioxidants, will last the longest (without needing continual repairs) and have the best water filtration. We've placed the water ionizers in this order on our comparisons page.

Getting the best water ionizer can make the world of difference for your own health and for your family.

Water Ionizer Machines

At Alkaline Water Plus, we have been studying and testing water ionizer machines (alkaline water machines) for decades. We know which alkaline water ionizer machines are the best and why. To see summaries of what we've learned over the years, including from testing the many brands of water ionizers, visit: Water Ionizer Comparisons and Water Ionizer Reviews.

On this page, the best water ionizers are placed in order of overall customer satisfaction, but each of them in their own ways are in the category of "BEST" to even be selected to be displayed here.

How Does a Water Ionizer Work?

A water ionizer produces water at one pole that is alkaline (which helps the body become pH-balanced and detoxifies it), and it also has an abundance of natural antioxidants. The pH of this water helps you release and remove toxins from the body (detoxify), and the antioxidants in this water is powerful in fighting free radicals. Free radicals are unstable molecules with an unpaired electron and are known to damage cells. They often steal an electron from other neighboring molecules to stabilize themselves. Free radicals are known to adversely alter lipids, proteins, and DNA and trigger a number of human diseases. Therefore the availability of an ample source of antioxidants can effectively prevent these DNA alterations and diseases.

A water ionizer system works by splitting the water into two streams. The water that comes out of the top is alkaline ionized water, described above. The water that comes out of the lower stream in a water ionizer is acidic water, which is good for skin, hair, watering plants and disinfecting. Splitting up water this way simplifies and reduces the size of the water clusters to make them more absorb-able to hydrate the body better.  

Water Ionizers Make the Best Water to Drink

Water ionizers are my favorite way to help alkalize my body. Not only do they produce the right pH water (to help my body get rid of its acid wastes), but they also remove Fluoride naturally (by splitting it out of the water into the acidic stream). Some of the better water ionizers will even filter out 99.999% of Fluoride, pesticides, pharmaceuticals, heavy metals and all other toxins. Water ionizers also produce high levels of molecular hydrogen antioxidants (the most powerful and safe free-radical-scavengers there are). So, on many levels and in many ways drinking ionized water lives up to its name for healthy living and reverse aging. 

It's always easier to stay healthy than to fight disease or cure it after the fact. Starting with our first water ionizer, 25 years ago, our lives have changed to be healthier. Raising our children was made to be so much easier, due to the elimination of allergies and sickness. 

Alkaline Water Benefits: One of the secrets of a longer and healthier life is to drink the right kind of water to nourish our bodies (and drink enough of it -- 8 or so glasses per day). Water is one of the most important factors in staying healthy. Alkaline ionized water, with its powerful anti-oxidants, is the most beneficial type of water you can drink.

Don't Buy Water in Stores -- Shop for Water Ionizer Systems

There is no practical way to get healthy, alkaline, ionized, antioxidant-rich water from the store. This is why we each need our own water ionizer. 

With ionized water, the antioxidants have to be consumed fairly quickly. Exposed to the air or in a plastic bottle they have a half life of only a few hours. That means that even if Essentia was beautifully ionized at the factory, any ionized water sitting in a plastic bottle for more than a day will virtually be void of all antioxidants they ever had. Hydrogen (the antioxidant in ionized water) seeps right through plastic very easily. I'm sure that Essentia (or any bottled water claiming to have the benefits of alkaline ionized water) has been sitting on the shelf for many days, or even weeks, and so is missing at least half of the benefits of ionized water.

If you are looking for the healthiest water, an alkaline water ionizer is the best water machine you can buy. With any other method of creating alkaline water you will not have antioxidants in that water. The one exception would be our Alkaline Ionizing Pitcher, but even with that the antioxidants will not be as abundant as with an electric water ionizer.

Cost Analysis: Bottled Water vs Ionized Water

Bottled water, even if it's alkaline, is in no way ever going to give you the benefits you can receive from a water ionizer. Also, if you think you're saving money buying water one bottle at a time, study the chart, below. A person could buy a water ionizer every year or two with the money they waist on bottled water.


Cost Comparisons Among the Types of Water Ionizers

Water ionizers, pH pitchers and hydrogen machines may seem expensive, but not when you compare their cost to even the cheapest bottled water. For instance, Walmart Great Value water at 88 cents per gallon would add up to $8800.00 over a 10-year period (of 1,000 gallons per year). You could literally buy 3 of my most expensive water ionizers for that. 

Information & Tips Regarding Installing and Using Water Ionizer

  • You can store ionized water in a way that doesn't lose its antioxidants. These are special bottles, which are stainless steel and vacuum sealed.
  • PH and ORP level displays on any water ionizer are approximate: Depending on your local water supply, the machine may tell you or show a pH level on the display that is different than the actual pH of the water that's been ionized. The reason for this is explained in this article: Water Ionizers Don't Always Work the Same in Every Location. 
  • If your source water is from your own well; from a whole-house softener; below 50 ppm of Calcium (hardness) or over 150 you should refer to whichever following page is appropriate to you, or just give us a call for assistance, to make sure you have everything you need. 

History of Ionized Water

The Japanese are famous for their in-depth study of water. At the height of their health crisis (after WWII) they turned their nation's health around with water. They studied the properties of healthy, healing waters around the world and developed water ionizers to make that kind of water. After successfully creating this product, they did animal studies and human, clinical studies to show that this water actually had quite a profound healing effect on the body. This is just a partial list of the diseases and conditions that ionized water has been shown to help: headaches, digestive disorders, diabetes, cancer, kidney stones, lack of energy, lack of memory, arthritis, allergies, obesity, hypertension (Read more about water ionizer research.)
