Water Ionizer Reviews & Comparisons

Accurate and honest water ionizer comparison information is still difficult to find after 12 years of searching. I post my own reviews on my water ionizer reviews page. I also expose many of the most blatantly dishonest sites (who pretend to have impartial water ionizer machine reviews) on that page too. With anything you buy today, you have to learn how to watch out for sales gimmicks, and so it goes with alkaline water ionizers reviews.

I make it a point to offer several brands, all of which I have tested against the other brands and am very confident have the highest quality in machine construction, reliability, overall performance, and water ionization capability.

The way I compare water ionizers is to carefully research, discover and share really useful details about water ionizers. My definition of careful research is to LOOK, compare and test machines. I don't get into the gimmick of breaking open machines to talk about my theories of why this machine is so good or bad. [A few companies do this without even testing the machine.] Intead, I use many SIDE-BY-SIDE TESTS and give you relevant facts that help you to compare water ionizers as objectively as possible.

Why Buy a Water Ionizer?

I purchased my first water ionizer 25 years ago, and it was so life-changing for myself and my family that, after retiring as teacher/principal in '07, I decided to build an online store (Alkaline Water Plus). With the AlkalineWaterPlus website, I educate the public about water ionizers, hydrogen machines, and filtered water. 

Watch this 10-minute video to learn the most important and compelling reasons for you to buy a water ionizer. 

What is a Water Ionizer?

A water ionizer is an electric-powered appliance that is usually attached to a standard faucet, although they can often be direct-plumbed. The device first filters the water, then ionizes the water by passing it through charged electrodes. The electrodes used in water ionizers are quite expensive, because the electrode plates are coated with platinum. 

Alkaline water and acidic water are both produced at the same time by the water ionizer. More can be learned about the ionization process, which is also known as electrolysis, on this page: Benefits of Ionized Water.

While acidic water has many valuable uses, it is the alkaline water that we want to consume for better health and longevity.

Types of Water Ionizers

There are four types of water ionizers: electric water ionizershydrogen water machineshydrogen gas machines (primarily used as an inhaler but can also make any liquid hydrogen-rich) and naturally ionizing alkaline water filters and pitchers. See each link to learn more about each type of water ionizer.  

This page is mostly focused on electric water ionizer comparisons and what you should know about purchasing the best water ionizer for you. You can go directly to the other pages linked here to find out more about them and how to compare them. 

How does an electric water ionizer compare to a hydrogen machine?

When hydrogen machines first came out, I tested them against water ionizers and found them to be very comparable for their ability to produce hydrogen (antioxidants). Hydrogen machines are fairly new on the market (within the last 5 years), and their warranties are not nearly as good as water ionizers. Usually you can get a good hydrogen machine for less initial cost than a water ionizer. 

Water ionizers have been around for 30 years. I got my very first water ionizer in the mid-90's. That very first water ionizer was not as good by any means than the newer ones I sell today, but even so it changed my life. Here's my testimonial.

So, which is better: hydrogen machine or water ionizer?

My personal preference is the water ionizer and here are my main reasons why.

  • With a water ionizer I virtually got rid of all my allergies, and this was a big deal for me. It changed my health and my life. I don't even get colds any more (and this has been consistent over the past 20+ years.) The dentist even noticed that I never got cavities any more.
  • Then I moved up to a better water ionizer in 2014, the Athena Classic. With the new water ionizer I noticed my spider veins went away. From this I supposed that the antioxidants produced by the new machine were better than the older water ionizer I had used for 16 years prior. So, I tested the two machines and found this to be true.
  • About a year ago I decided to switch to a hydrogen machine, because it produced equal antioxidants to the water ionizer I was using (or maybe even a bit more). At the time I theorized that perhaps it was the hydrogen that was responsible for all of the benefits I've received from drinking ionized water over the years. At least I wanted to test this theory. However, after about 4 months of drinking almost exclusively hydrogen water (from a hydrogen machine) I started getting some of my old allergies back. My spider veins didn't come back though...just the allergies. 
  • I believe allergies are a sign of the body's pH balance being off causing the body to be unable to rid the body of toxins.
  • So, I went back to using my water ionizer, for the most part, although I still like my various hydrogen machines and use them sometimes. I've stabilized my body pH back to being balanced and so, again, all allergies are gone.

Hydrogen water machines give you the antioxidant benefits, but not all of the health benefits that ionized water can give you.

One cautionary note about hydrogen machines: Only the hydrogen water machines and hydrogen gas machines which use DuPont's SPE/PEM membrane are safe. Therefore we do not sell any hydrogen water or hydrogen gas machines which do not use the DuPont SPE/PEM membrane. The reason is that this membrane removes toxic oxides, ozone, and chlorine from the hydrogen water produced, and so makes it safe to drink. Our Hydrogen Water Machines page has some comparisons between the various hydrogen water generators we sell. 

What is pH and what does it measure?

The term “pH” stands for the “power of hydrogen.” The “H” is capitalized in the standard abbreviation, as it represents the chemical symbol for the hydrogen element.

PH is a measure of the acidity or alkalinity of a solution. The scale ranges from 1 (very acidic) to 14 (very alkaline.) The pH scale is a logarithmic scale, meaning that water with a pH of 8 is 10 times more alkaline than 7 pH, neutral, water. Water measuring pH 9 is 100 times more alkaline than neutral water, etc.

As the body ages, the pH balance within it becomes more acidic. Many people theorize that it is this acidity that accelerates disease and aging. A water ionizer contributes to helping the body regain its youthful balance, by providing the body with many alkaline buffers with each sip of ionized water you consume. The alkalinity in ionized water isn't disruptive of the stomach, because it contains no calories and so just passes quickly through the stomach on its way to your cells.

PH is easy to measure with pH reagent solution or pH test strips. You can test your own body's pH by testing your saliva with pH test strips.  Request a free pH test strips kit now.

What is ORP and why does it matter?

“ORP” stands for “Oxidation Reduction Potential,” and in simple terms it prevents deterioration within the cells caused by oxidation. Oxidation is like rust, and a negative ORP prevents or reverses that kind of thing happening in the body. 

You can see the ORP comparisons at point #18 in the chart, above.

What is Molecular Hydrogen and why does it matter?

Molecular Hydrogen is a molecule created by a light bond between two Hydrogens. It's considered to be "free hydrogen" in this state. Ordinary water contains hydrogen, but not free hydrogen.  When hydrogen is free it can fight free radicals; ordinary water cannot. Molecular hydrogen is proven to be very beneficial to the body, and I invite you to visit my special page all about these scientific studies using molecular hydrogen. Molecular hydrogen has been proven to have no toxic effect whatsoever. It is able to prevent and even repair free radical damage. I haven't done nearly as much testing of molecular hydrogen levels, because the testing methods haven't been perfected yet. Molecular-hydrogen-levels testing for water ionizers and hydrogen machines is a fairly new and somewhat crude science right now. It's also very expensive. You can see the test results from what I've done so far posted in column 18a.  

Molecular hydrogen is important, and is capable of acting far more powerfully than any antioxidant, yet has no harmful effects. If there is no need for molecular hydrogen in the body at that time, it does nothing: just evaporates without a trace. This safety factor of molecular hydrogen really puts it in a category of its own. Read more about the benefits of Molecular Hydrogen.

The H2 Water Ionizers and Smart Water Ionizers so far test the best in Molecular Hydrogen. 

Note: No matter what type of ORP or molecular hydrogen tester or solution you buy, there is no guarantee as to what results customers will get when they test. There are too many variables with ORP and Molecular Hydrogen testing to guarantee these results.

Comparing Hydrogen Water Machines: There are many ways to produce hydrogen water. Here is an example showing some comparison testing of water ionizers I've done. You can find more testing by searching my blog.  

How is the Alkaline Water Plus Water Ionizer Comparison Chart different than the reviews on other water ionizer sites?

You can count on the details of my water ionizer comparisons as well as my reviews to be accurate. It took me years to compile and I work on it regularly to keep it up-to-date.

In this modern age, over 80% of consumers research a product online before making a purchase. Some unscrupulous vendors of water ionizer machines have taken advantage of this fact by posting fake reviews that have either been written by themselves or by others who have been paid to write favorable reviews. Some have even gone so far as to issue themselves made-up awards and certifications.  While I have no issue with someone posting their opinions about the products they sell, I feel the practice of doing so under a false name or hiding one's identity can be misleading and is disingenuous.

Some other sites focus on physical features vs. the performance of their water ionizers. This is often the case when the performance is just average.  Focusing on physical aspects is another way of misleading customers. The "bigger is better" theory has been dis-proven with respect to electronics many years ago. Bigger and more does not equate to being better when it comes to water alkalizers. While it is true that frequently, those water ionizers with more plates do process the water faster, this doesn’t necessarily make for a better product. My testing demonstrates this.

I believe that real, hands-on testing and analysis of the various features of each water ionizer is vital. I’ve taken the time to perform the testing myself, and am publishing the results here.

All of the components of a water ionizer work together to give testable results. In many cases, I’ve found that certain five-plate and seven-plate water ionizers get better results than a 9, 11, 13 or even 15-plate one. This statement is based on actual comparison testing of water ionizers. I look at the whole design, the water cell, filtration, internal cleaning, and flow-rate, but in the end the actual water ionizer comparison side-by-side testing is the most important thing. I have not found other companies that do this, and many companies even discourage side-by-side comparisons of water ionizers (which I find to be suspicious.) The water ionizers on the above chart are rated for overall performance on point # 15.

At Alkaline Water Plus,we give you the straight facts about the best and/or most popular alkaline water machines [water ionizers]. We sell a wide range of hand-picked exceptional alkaline water machines. We’ve compared the most popular and the best water ionizers in every conceivable way on this comprehensive water ionizer comparison page and also on our alkaline water ionizer reviews page. Alkaline Water Plus has taken the time to effectively and completely compare alkaline water machines and report the information we’ve discovered about the following water ionizers: Jupiter Athena, Athena H2 water ionizer, Vesta H2 water ionizer, Delphi H2 Undersink water ionizer, Smart 7P and 9P water ionizers, Enagic water ionizer (Kangen water machine), Melody II water ionizer, Chanson Miracle Max, Nexus X-Blue water ionizer, Alive Real Spirit Aqua Ionizer Deluxe, Aqua Ionizer Deluxe 9.5, Excel IE-900, Excel MX-99, Chanson Royale Undersink water ionizer, Tyent ACE-13 water ionizer, Tyent Turbo MMP-9090 Turbo Extreme water ionizer, and UCE 11 undersink water ionizers, Lifeionizer MXL-15 water ionizer, Ayana Vitality Varunizer, Bawell Platinum water ionizer, and the Alkaline Ionizer Purifier Energizer by AOK Health.

Which water ionizer is best?

I suggest you read this entire page and chart, as well as the product page of the water ionizer you're considering. Then, to make sure you get all the data, you should read my water ionizer reviews page, and then make up your mind as to which water ionizer is best for you. I’ve tested and studied most of the water ionizers myself, and my reviews and data are based on first-hand observation and testing. Decide which water ionizer features are most important to you, then use the above chart to make your comparisons and final decision. The Alkaline Water Plus water ionizer comparison chart will help you compare the important water ionizer features at a glance, and is more accurate and detailed than any other review or water ionizer comparison site you will find.

How are Alkaline Water Machines Compared?

Anyone doing water ionizer comparisons should compare only “apples-to-apples”! When looking at water ionizer comparison videos, it’s important to compare only those water ionizers tested at the same location and time. And remember that although a water ionizer may compare favorably for one set of tests, you should attempt to view several tests measuring numerous qualities of the machine before making a final decision.

I understand that not everyone has the time and patience to individually test every single water ionizer on the market. This chart is my effort to leverage my 2 decades of experience with water ionizers to provide consumers with a simple comparison chart to find the machine that best matches their criteria. Short of testing every single feature, there is a good rule of thumb regarding the quality of water alkalizers - the higher quality machines have the better cleaning systems, better filtration and produce the highest levels of molecular hydrogen. I describe these features in further detail, below.

Finding a Superior Water Ionizer

The most important factor to consider when comparing water ionizers is the healthiness of the ionized drinking water. In the chart, points #15 & 18, I have placed greater emphasis on the water ionizer in each set of tests that was able to produce the highest Molecular Hydrogen levels & ORP per unit of pH and declared that water ionizer the best for that series of tests. I did this comparison using level 3 [or that water ionizer’s 9.5 pH level] to demonstrate the ORP results for the most popular and common drinking level of ionized water. The strong acid and alkaline by-products of the water ionization are non-drinkable, and though they are great features, only you can decide if these should be the determining factors in your final purchase, or whether factors such as price and ORP level take precedence.

Testing and Comparing pH and ORP

A very important factor to consider when comparing water ionizers is the pH and ORP [antioxidant] levels for each machine at the appropriate settings for frequent drinking. It is both through testing and looking at the whole design of the water ionizer that will help make this comparison. You can find this in the chart at point #18. The ionizer with the best overall design will allow that water ionizer to get better ORP per unit of pH in comparison tests. The only way to do this is through side-by-side comparisons,

First consider how strongly the water ionizer can ionize [#16-17].  Keep in mind that one only needs the pH to range from about 3 to 11 for all purposes, and from about 8.5 to 9.5 for drinking purposes. Then look at the ORP per unit of pH the water ionizer is able to produce — the more negative ORP the better [#18]. Focus on the drinking-levels of pH for your ORP [antioxidant] readings.

Is Water Ionization the Same for All Alkaline Water Machines?

Not all alkaline water machines are the same. Some water ionizers perform better than others. I've summarized all this in the above chart. Ionized water with a very high pH but low ORP (oxidation reduction potential) wouldn't be good, simply because you can get better than that. It's good to be able to get a variety of pH, and with it get an abundance of molecular hydrogen to fight free-radicals throughout every cell of your body. 

I don't recommend alkaline water machines which use a lot of power (watts), because over time this can damage plates.

Companies that attempt to persuade you that their water ionizer is better because of plate sizehigh watts or other superficial reasons should be able to show you testing that proves their water can give you better results, but they can't. These companies, such as Tyent and Life, don't show side-by-side comparisons, because their water ionizers do not compare well. 

Kangen water is chemically the same as alkaline ionized water, and can be tested for pH and ORP like any other. Occasionally I'll hear hype about this, but ionized water is ionized water. The differences that make one water ionizer better than another one can all be found and explained thoroughly on this page.  

Plate Cleaning - A Measure of Quality

A water ionizer with automatic, continuous-cleaning will naturally last longer and get better results than a water ionizer with only the normal automatic cleaning.

To find the best water ionizer, after comparing the pH and ORP capabilities, compare the water ionizers’ automatic internal plate-cleaning systems. You can find this at #13 in the chart, "Cleaning Type & Quality". A good cleaning system is the only way your machine will continue to produce the best ionized water in years to come.

The electrodes are the heart of the water ionizer, and the machine will cease to ionize well if the plates aren’t kept clean, pretty much every second. What happens with the ordinary automatic cleaning systems is that the the electrodes develop a calcium film over time, because they're not cleaned constantly. A calcium film on the plates will reduce the water ionizer’s capacity to ionize water [pH & ORP]. However, if the electrodes are kept pristine clean and free of calcium, then your water ionizer will continue to be able to produce the best high-pH, low-ORP [high antioxidant], water as if it was brand-new out of the box

Another reason to examine the water ionizer’s plate cleaning process is convenience. Intermittent automatic cleaning, otherwise known as acid washes, requires that you have to wait for the acid wash to finish. Sometimes this can occur at the beginning of every use and at other times it happens periodically throughout the day. Acid washes result in wasted water and reduced filter life. Enagic/Kangen, Tyent, Venus, Chanson, Nexus X-Blue, Lifeionizers, Bawell, Alive/Aqua Ionizer Deluxe, Ayana Vitality and most other water ionizers use intermittent acid washes.

Water ionizers which have automatic, continual cleaning not only clean your water ionizer plates 50-75% more thoroughly, but they also have NO inconvenience or wasted water. The H2 water ionizers and Smart water ionizers all use automatic continuous-cleaning.


Each water ionizer has at least one filter in it, sometimes two.  Some companies have gone through the process of having their filters lab-tested, and some just report the filter media used. We have analyzed these filter systems and  have reported their features in the chart, above, # 34, #35 and #36.

If you live in a municipality where your water is treated, then I would recommend using filters which remove Chloramine and Fluoride, which is added to your tap water. Because Fluoride is an acidic mineral, it is discharged by all water ionizers in the process of creating alkaline water.

Using a slow flow rate and a filtration system is key to removing all Fluoride if this is important to you. As a side-note about Fluoride, all water ionizers will remove about 50-75% of Fluoride as part of the water ionization process. Because Fluoride is acidic, it will tend to be diverted to the acidic-water stream during ionization.

Changing your filter properly at recommended intervals is an important part of getting good filtration. A filter counter can help remind you when it’s time to change filters. The only ionizer in the chart above that doesn’t have a filter counter is the Enagic SD501. The quality of water source can drastically impact filter life. For this reason, most water ionizer companies report the filter life conservatively.

I offer a free report on water quality for your area, which you can access by visiting my Free Water Quality Report page.

Well Water Filters

The best water filter for a well owner is a .01 filter, which filters lead, chlorine, bacteria and many other undesirable substances. Additionally, if you use well-water, I recommend using a small prefilter, called the Primary Well-Water Filter. When you do this, you protect your water ionizer from the potential, periodic, large influx of sediment, common to wells, which can ruin your more expensive filters.

Which Water Filters are Best?

All of the water ionizers I sell have good water filters, but the Jupiter Athena Classic alkaline water machine and the H2 water ionizers have the best water filter selection. UltraWater filtration is better than any other type of water filtration system. I encourage you to keep the quality of the drinking water in mind when comparing water ionizers. However I offer all of the best water filters to add externally to your water ionizer to clean your water perfectly, customized to your source water needs, no matter which water ionizer you buy.

Plating Process and Types of Plates

The plating process [#28 in the chart, above] and the type of plates [#27] are very important features to look at when comparing water ionizers. There are various techniques used for creating the plates that function as electrodes in a water ionizer. These techniques are described below, along with their benefits or drawbacks.

Solid Plates that are Electroplated: Electroplating uses electricity to coat the electrode plates with platinum. Generally this process is more thorough than other methods of coating the plates, and it produces a greater surface area for better electrolysis, which improves ORP. The Jupiter and Nexus alkaline water machine manufacturers both import their plates (water cells) from Japan. They use similar patented electroplating techniques to coat their plates for better platinum bonding, which results in less likelihood of air or dust to become trapped in the coating, and an irregular surface area composed of micro-peaks and valleys for more efficient electrolysis. This allows for a greater surface area that uses less power to generate electrolysis. Nexus describes their plating process in this plate comparison.

The Mesh Plate Design: Similar to the electroplating process, mesh plating is applied to a solid plate and then the entire plate is electroplated. This is an even more efficient design to boost electrolysis by way of increasing the surface area of the electrode without significantly increasing the mass, but I only advocate the use of mesh plates with water ionizers that also have continuous-cleaning internal plate-cleaning systems as part of their design. Provided the plating and cleaning of the mesh plates is done correctly, using mesh plates to enhance electroplating is a great innovation in water ionizer design. It allows for greater electrolysis without drastically increasing wattage. High wattage will wear the ionizer out more quickly than lower wattage. In water ionizer comparison testing I have found that water ionizers using the combination of mesh plates along with continuous-plate cleaning get the best ORP per unit of pH at the drinking levels of ionized water.

Dipped Plates: When “dipping” is used, the surface area for electrolysis will be small unless the company uses large plates. One cautionary note about dipping methods of plating is that air bubbles are inevitable. Some manufacturers get around this by dipping and baking and re-dipping, which may eliminate the air bubble, but the multiple coats of platinum aren't guaranteed to stick to the plates forever. Over the years the platinum could erode off the plates unless special bonding techniques are used. This is why using plates (water cells) made by a manufacturer with the most expert engineers in the field is a very important thing to consider when buying a water ionizer you want to last.

Size of Plates: Using large plates is necessary in the case of using dipping methods of plating. Large plates aren't particularly desirable though, because they require much more energy to generate electrolysis. Excessive use of electricity with electrolysis plates is risky, because these plates will tend to experience more wear and tear over the years. Larger plates with more watts is not a better plate design. Large plate ionizers usually require a fast flow rate to keep them cool, which means that the filtration with the large plate ionizers will not be as thorough as their competitors’ ionizers. Large, dipped plates are used by Enagic, Tyent, and Life water ionizer companies.

Customer Service Considerations when Purchasing a Water Ionizer

Several points in the chart [#2-14] are related to customer servicing considerations and assurances. Each of these points are quite important in and of themselves, but together as a whole they paint a picture of longevity, reliability and excellence or not [or somewhere in-between]. Does the water ionizer company you’re considering have a repair depot in the U.S. and does it offer a 60-day satisfaction guarantee? Free shipping? Good warranty? Is the importer a BBB member? Do they give an accurate location for themselves? Also, I have indicated if the satisfaction guarantee has any strings attached, such as a re-stocking fee. The Jupiter, H2 Series, Nexus and Tyent water ionizer companies all offer lifetime warranties. Chanson, KYK, and Ayana offer 10-year warranties, and the Enagic Kangen water company offers a 5-year warranty. There are variations in these warranties and I have included additional columns to clearly show how each company’s warranty will affect you.

Water Ionizer Power Requirements

More amperage & watts going through the plates is not necessarily better. Most manufacturers keep the wattage to 150w or less, but some water ionizers are capable of using over 250 watts. I believe that the more long-lasting water ionizers will prove to be the ones using the lower watts.

Water Ionizer Price Considerations

Does a high price mean that particular water ionizer is better? Not necessarily. I have found that price does not necessarily equate to better quality in a water ionizer. Choose the water ionizer features that are important to you, then use the comparison chart above to find the right machine for your needs. While some water ionizer companies may make claims to sell “The Only Real Water Ionizer,” or “The Cadillac of Water Ionizers,” these are simply sales slogans.

I object to sales people making false claims and using scare tactics and I consider this to be a very poor business practice. Look at the things listed above with any water ionizer you’re considering, and you’ll find the best ionizer for you. I encourage potential water ionizer buyers to get the real facts from an objective and knowledgeable source.

I’ve been drinking ionized water for over 25 years now, and I’m convinced that water ionizers DO work to help people with their health. Years ago my first water ionizer helped me enormously. The biggest problem I had was allergies, and with my water ionizer, they all disappeared. This was with a far inferior water ionizer than the ones above. [It only got about -250 ORP per pH level of 9.5, whereas the good ionizers I sell today get up around -300 to -600 ORP at that 9.5 pH level.] With that same inferior water ionizer my health and the health of my five children changed drastically. Prior to drinking alkaline water, we all made regular doctor visits for the usual complaints - sore throats, ear infections, and allergies galore, but after regular alkaline water use, we were able to reduce these visits to simple annual well child check ups.

The water ionizers I sell on my site are all there because they’re good ones. I refuse to sell a water ionizer that is poorly designed. Each are comparable with the rest. While some may outperform the others in certain areas, they probably are the underdog in other categories. Buying a water ionizer boils down to personal choice and budget. I have tested the highest-priced water ionizers with great expectations, but found them to be comparable with the others, and often not even better in the most important categories.

Do not be fooled by a sales person’s hype if they attempt to imply their water ionizer is the only one that has health benefits or performs certain functions. It just wouldn’t be true. The Japanese Health Department recognized that ionized alkaline water from water ionizers had proven health benefits and described water ionizers as health devices. This recognition was given with no regard to a particular brand. The origin of the development of water ionizers was Korea and Japan, which built off of the knowledge of the other. Korea recognizes water ionizers made in Korea as medical devices [provided they are good enough] and Japan recognizes the water ionizers made in Japan.. that’s how it works. Each country examines its own manufacturers’ devices. Jupiter, KYK and Tyent are all approved by Korea to make medical devices, and in Korea their water ionizers are recognized as medical devices.

I have first-hand knowledge of people who many years ago [when I bought my first water ionizer] experienced unbelievable health benefits from ionized water. Most of the water ionizer companies today didn’t exist at that time. As a matter of fact, back in the 70’s Michael Moon [the founder of Jupiter water ionizers] was a very wealthy manufacturer with failing health. He was introduced to water ionizers by a friend, and after regaining his youthful health with a primitive crude water ionizer of the time he decided to develop the superior quality Jupiter water ionizers we have today.

Life Water Ionizers

You may also notice that we don't sell or even advocate Life Ionizers [Life MXL-15, MXL-13, Life 7600, Life 8100, Life 9200, ...or any Life water ionizer]. We offer some comparisons on the above water ionizer comparison chart, but we are limited in that we don't trust what the LifeIonizer company says about themselves. You can read on our Water Ionizer Reviews page more about why we don't trust them.   

There are other companies who use tricks to sell their water ionizers too, and we expose them on our Water Ionizer Reviews page too.

Enagic Kangen Water Ionizers and Impart Excel Water Ionizers

Alkaline Water Plus also doesn't sell the Enagic Kangen Water Ionizers. The reason for this is not that they're bad water ionizers at all. You can see on the chart that they rate among the better water ionizers. We don't sell them due to an exclusivity clause in their marketing contract, which would require us to sign that we wouldn't sell other brands.  

The Enagic company warns their customers about the potential plate damage that could be caused by utilizing their strong-acidic-water setting too frequently or improperly. It is very important, when using the Enagic machine, to follow the manufacturer's instructions (especially when it comes to excessive use of the saline solution and making sure to periodically clean it of calcium build-up as well).

See Enagic’s warning page here:


Fake Water Ionizer Comparisons Come in Many Forms

  1. The biggest water ionizer comparisons scam is when the company puts up a review site, pretending it is independent and non-biased, when it isn't. I've written a lot about this in my Water Ionizer Reviews page.
  2. Beware “water ionizer comparisons” that show only the highest or strongest pH/ORP for that water ionizer and/or doesn’t show you their testing. This practice can be misleading because you don’t drink at the highest alkaline level, so the ORP for that level is irrelevant.
  3. What you should really be interested in is the hydrogen (H2) levels or ORP for the pH level you will be drinking.
  4. Unless the water ionizers are being compared side-by-side in the same location, at the same time, using an ORP meter or Trustlex hydrogen tester that is cleaned and calibrated prior to each test, the comparisons are potentially false readings.
  5. I am one of the only people who actually shows the extensive testing among water ionizers on YouTube. When I do this it adds to the general knowledge about various water ionizers and also shows that water ionizers perform differently in different water sources.
  6. Another fake water ionizer comparison trick is to make claims based on saying their ionizer is the only medical device available. No water ionizers are considered medical devices in the US. The KFDA [the Korean equivalent of FDA] and the Ministry of Health of Japan both recognize water ionizers as medically useful devices, and so will certify them.
  7. One, more recent trick is to make claims that ionized water is not natural, because it’s not found in nature. The claims are being made by people who want you to buy their products [usually filtering-only devices] instead of water ionizers. But, the idea that ionized water is somehow not natural is simply misguided. It can be tested and found to be water [two hydrogens to every oxygen]. There are normal, healthy minerals in ionized water, such as calcium. There are also many more benefits of ionized water.
    • I don’t have anything bad to say about filtering-only alkaline water ionizer devices. I sell a few. The most popular one is my new Alkaline Plus Pitcher which can bring the pH up slightly [about 1 point higher than the source water pH, i.e. from 8.5 to 9.5 or from 7.5 to 8.5] and it delivers about -200 to -400 ORP [antioxidants] on average. I think it’s a great product, and I think everyone should buy one, even if they have a regular water ionizer, because they will be traveling sometimes and will need it.
    • However, I don’t believe anyone can experience the full health benefits of using alkaline water when they only use a filtering-only water ionizer [also called portable water ionizer]. I use them only when I travel. The portable water ionizers work, but the electrical water ionizers work better and faster. I have tested them all and the health benefits are better with a regular [electrical] water ionizer.

I look upon a water ionizer as a tool that can be used to adjust the buffers we all need up or down as desired. After over 25 years of using water ionizers for myself and my whole family, I can say that they are the single best thing I’ve ever purchased to improve my health. I am very health conscious about the products I buy, but have never found a better product to recommend to others than an alkaline water ionizer.

Comparing Electric Water Ionizers with Hydrogen Machines; Non-Electric Water Ionizers and Alkaline Ionizing Filters.

In addition to electric water ionizers, other kinds devices are beneficial to your health in that they can give you similar antioxidants or molecular hydrogen in varying amounts. I have tested and used all kinds of Molecular Hydrogen producers and like them. I personally own and use all three types of water ionizing devices. They are very different from each other, but they compliment each other. Learn more about that. https://www.alkalinewaterplus.com/blog/comparing-molecular-hydrogen-generators-and-water-ionizer-machines-and-filters/ 

These days one can get some pretty good alternatives to the traditional electric water ionizers (above), but as previously stated they are not necessarily less expensive in the long run. Here are some other pages about these options and how they compare:

Why do we have a Natural Alkaline Water System on our chart?

That water system is on our chart to show a few comparisons with water ionizer systems. Many natural alkaline water systems are fine water filters, but do not filter fluoride or ionize the water. The Alkaline Ionizer Purifier Energizer does alkalize, filters well and produces a good amount of antioxidants, but most other ones do not. Some do not produce any antioxidants whatsoever, zero Molecular Hydrogen. So when a company claims it cleans and structures the water look for side-by-side comparisons with water ionizer systems. There simply is no comparison. That is my point in putting it in the chart. There are many, many years of research and hundreds of water ionizer research studies standing behind the amazing benefits of ionized water and water ionizer systems, which you should read.
