Why is this Water Ionizer Comparison Chart so different than Other sites comparing Alkaline Water Machines?

The smartest people I know go straight to the comparison and review sites when they decide to buy something expensive, like an alkaline water machine. To me, that’s an excellent idea, however you should beware that most of the water ionizer review sites that you will come to are actually just giving the opinion of the site-owner. Naturally, people are entitled to their opinions, of course, but rather than giving credibility to “awards” [which are generally made-up and can be handed out randomly by pretty much anyone] I believe that real, hands-on testing and analysis of the various features of each water ionizer to be much more helpful and reliable.

Another thing you may or may not notice about my chart is that, while I do make reference to the number of plates and number of watts in the various water alkalizers, I don’t always call the water ionizer with the most plates or highest watts the best. That’s because I’ve noticed when testing the different water ionizers that it did not add up to better results in many cases. Bigger and more is not always better when it comes to water alkalizers. Of course I will report when it is better, but really I have tested and tested and the bigger is better theory, with regard to water ionizers, just doesn’t add up.

There are several top water ionizers that have only 5 plates. How is this possible? It is an engineering feat that water alkalizers can even do what they do. They split the water, ionize it, transform it, all very quickly as you hold your glass under the water ionizer’s spout. The engineers who design the plates, also design the water cell [the structure that holds the plates, controls the flow, cleans the plates, distributes the electricity, etc.] All of these things, working together is what makes or breaks the ability of a water alkalizer to alkalize and ionize the water. It is not just one thing, such as number of plates. There is one thing that normally is true about 7, 9, and now 11-plate water ionizers that makes them top water ionizers, is that they can ionize the water faster [usually]. Faster ionization is another feature that a consumer may or may not want. I actually like my water ionizer to ionize at about a 1.5 quart/min. flow-rate. The reason I like this, rather than a 3-quart/min flow-rate is that the filtration will be far better at the slower flow-rate.

In many cases I’ve found a five-plate water ionizer getting better results than a 7-plate one. I have found through years of comparison testing that it is a whole design, the water cell, filtration, internal cleaning, and flow-rate all working together to get results. I can assure you that all water ionizers on the above chart [except where noted], and certainly all that we sell, have gotten good results and will do a good job ionizing your water for you.

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. Also, even though a water ionizer is best in one set of tests, you should try to see several tests of that water ionizer before making a judgment.

Ideally, one should set up all the water ionizers in one location, and use them equally, and test them periodically to then see which water ionizer continues to be the best — over time. But, short of that, we can predict this pretty well by looking at the cleaning systems to see which are the best [see below for more about automatic plate-cleaning systems].

How can you tell if a water ionizer is superior?

The most important factor to look at in comparing water ionizers is the healthiness of the ionized drinking water! In the chart above, where I’ve reported water ionizer comparison tests, I have placed emphasis on the water ionizer in each set of tests that was able to produce the best [healthiest…highest ORP per unit of pH] water for you to drink 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] in order to put emphasis on the importance of testing the most popular/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 they should take precedence over either the healthiness of the ionized water you can get from the alkaline water machine you buy… or your budget.

Testing and Comparing of PH and ORP

The most important ways to compare water ionizers are to compare the pH and ORP [antioxidant] levels at your drinking water levels. It is both through testing and looking at the whole design of the water ionizer that ultimately one will find the best water ionizer. The ionizer with the best overall design will allow that water ionizer to get better pH and ORP in comparison tests. The only way to do this is through side-by-side comparisons, First consider how strongly the water ionizer can ionize. Then look at the ORP per unit of pH the water ionizer is able to produce — the more negative ORP the better.

Plate-Cleaning Quality & Cleaning Type

After comparing the pH and ORP capabilities, compare the water ionizers’ automatic internal plate-cleaning systems. Why do I say you should compare the water ionizers’ cleaning systems? A good cleaning system is the only way your water will be able to continue to produce the best ionized water in years to come. It’s very important to keep the electrodes clean [not just clean them periodically]. The electrodes are the “heart” of the water ionizer. If the electrodes can be kept squeaky-clean, 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! If the water ionizer isn’t kept internally cleaned well enough, then the electrodes will develop a calcium film [or scale build up] on them. This will reduce the water ionizer’s capacity to ionize water [pH & ORP] over the months and years.

Another reason to examine the water ionizer’s plate cleaning process is convenience. Regular 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 about once or twice per day. Acid washes usually end up in waisted water and filter-life as well. Enagic/Kangen, Tyent, Venus, Chanson, Nexus X-Blue, Lifeionizers, Bawell, Alive/Aqua Ionizer Deluxe, Ayana Vitality and actually most water ionizers do this method of acid washes.

The Chanson VS70 does water ionizer acid washes after you’re done pouring, still wasting your filtered water, but at least not creating an inconvenience.

Water ionizers which have automatic, continual-cleaning not only clean your water ionizer plates much, much better, but they also have NO inconvenience or wasted water. These water ionizers use continuous-cleaning: Melody, Athena, Delphi, Nexus Smart and Vesta GL.


If you live in a municipality where your water is treated…the best water filters are those which remove Chloramine and Fluoride, which the municipalities put into your treated water. By the way, all water ionizers remove Fluoride because Fluoride is an acidic mineral and will go out the acidic hose to a great extent. How much will be removed this way depends on your water ionizer and the setting/flow-rate you’ve got it on. If you are really determined to remove all Fluoride, then the best way to do this is to both filter and ionize it out of your water.

Changing your filter properly, when its “life” is used up, is an important part of getting good filtration. It’s good if a water ionizer has a filter counter. With a filter counter you can more accurately see when it’s time to change your filter. The only ionizer in the chart, above, that doesn’t have a filter counter is the Enagic SD501. The variability of water source makes it impossible to tell for sure when a filter’s “life” is used up. For this reason most water ionizer companies report the filter life conservatively.

Well Water

The best water filter for a well owner would be a .01 filter, which would filter out lead, chlorine, bacteria and many of the thiings that water treatment companies do for municipalities.

Best Water Filters

All of the water ionizers I sell have good water filters, but as far as which alkaline water machine having the best water filters, the Jupiter alkaline water machines have the best water filter selection. 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, in-line with your water ionizer to clean your water perfectly [customized to your source water needs] no matter which water ionizer you buy.

Plating Process and Type of Plates

It does make a difference which techniques are used for the plating process. Here are explanations of the various types of plates and their platinum-coating methods.

Solid Plates that are Electroplated: What electroplating does is scientifically and electronically coats the electrode plates with platinum. Generally this process is more thorough and produces a greater surface area for better electrolysis, which means better ORP. The Jupiter and Nexus alkaline water machine manufacturers use similar, patented, spraying/electroplating techniques to coat their plates for better platinum bonding, less likelihood of air or dust to become trapped in the coating, and an irregular surface [peaks and valleys] for more efficient electrolysis. This allows for a greater surface area for better electrolysis without needing to increase the wattage. Here is the Nexus explanation of their spraying methods.  See this plate comparison.

The Mesh Plate Design: Mesh plates are used for similar reasons as the electroplating process, above. Mesh is usually 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. The Athena, Delphi and Nexus Smart water ionizers use mesh plates. Provided the plating and cleaning of the mesh plates is done correctly, using mesh plates and electroplating is a great innovation in water ionizer design. It allows for greater electrolysis without having to use too high of a 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: Comparatively, when “dipping” is used, the surface area for electrolysis will be small unless the company uses large plates. Using large plates is necessary in this case if you want to compete with manufacturers who use electroplating or mesh. When one uses large plates one needs to increase the wattage of electricity going to the plates in order to even ionize at all. Larger plates with more watts is not a better plate design. When more power is loaded into the plates the chances of damage to the plates over time is increased. Platinum, like any metal, will melt if it reaches a certain temperature. This is definitely not desirable. The way the plates cool themselves is by cold water running over them. Large plate water ionizers require a faster flow-rate because of this one factor. Large, dipped plates are used by Enagic, Tyent, and Life water ionizer companies.

Company User-Friendliness

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? Also, check to see if the satisfaction guarantee has any strings attached, such as a re-stocking fee. The Jupiter, Vesta, 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 what how each company’s warranty will affect you.


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


Does a high price mean that particular water ionizer is better? No,in my experience I have found that price does not necessarily equate to better quality in a water ionizer. The ways to find out the better water ionizer are all specified above. Do not allow a company to tell you that it’s the “only real water ionizer” or that it’s “the Cadilac and all others are Fords”. These are the kinds of statements that sales people use to try to get you to buy a more expensive product. I object to sales people making false claims and using scare tactics. I consider this to be very dirty selling tactics. Look at the things listed above with any water ionizer you’re considering, and you’ll find the truly best [no hype] one for you. I encourage potential water ionizer buyers to get the real facts from someone more objective and knowledgeable.

I’ve been drinking ionized water for over 20 years now, and if there’s one thing I do know, it’s 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 they all went away! 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.] Also, with that same inferior water ionizer my health and the health of my kids [I have 5 kids] changed drastically. We all went from each seeing the doctor twice a year each…for ear or throat infections, allergies or something like that, to only well-child check-ups or in my case, no visits at all!

The water ionizers I sell on my site all there because they’re good ones. I refuse to sell a water ionizer that is inferiorly designed. They’re all fairly comparable with each other. Even though one is best in one area…it may not be best in another. It really does boil down to personal choice and budget. I have tested the highest priced water ionizers with great expectations, but found them to be simply comparable with the others, and often not even better.

The main point of saying this is: you should not be fooled by a sales person’s hype if someone is trying to imply their water ionizer is the only one that can cure people, or something. 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 actually in both Korea and Japan…they built off of each 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 that people many years ago [when I bought my first water ionizer] were experiencing unbelievable health benefits from ionized water. Most of the water ionizer companies today weren’t even born yet. 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 Life Ionizers [Life 7600, Life 8100, Life 9200, etc.] are not compared on this page. Read these articles to find out why we do not trust or compare most Life Ionizers. We don’t deal with the Lifeionizer company for the most part and have only tested one of their ionizers for this chart. I don’t advocate Lifeionizers and you can read more about it here.

Fake Water Ionizer Comparisons Come in Many Forms

Watch out for “water ionizer comparisons” where the water ionizer comparison chart shows only the highest or strongest pH/ORP for that water ionizer and/or doesn’t show you their testing. That is misleading for two reasons: 1) You don’t drink at the highest alkaline level, so the ORP for that level is irrelevant. What you should really be interested in is the ORP for the pH level you will be drinking. 2) Unless the water ionizers are being compared side-by-side in the same location, at the same time, using an ORP meter that is cleaned and calibrated prior to each test, you will have many potential false comparisons. 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.

Another fake water ionizer comparison trick is to make claims based on saying their ionizer is the only medical device. No water ionizers are considered medical devices in the US. Also, in Korea, the KFDA [the equivalent of the US FDA] and in Japan, the Ministry of Health, both recognize that all the water ionizers I sell are medically useful devices.

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. But, the idea of ionized water not being natural is just silly. It can be tested and found to be water [two hydrogens to every oxygen]. There will be also found to be normal, healthy minerals in ionized water, such as calcium. There will also be an abundance of extra electrons, which are nature’s most natural anti-oxidants. If you go and stand next to the ocean, 5 feet away, and breath the air you may feel energized by it. What is different about that air? It has an abundance of extra electrons in it. Electrons are negatively charged and are able to be donated to active oxygen [also called free-radicals] in the body. This instantly makes the oxygen able to be used properly by the cells of the body and prevents free-radical damage to the cells. You will find nothing more in this water.

I don’t have anything in particular bad to say about filtering-only alkaline water ionizer devices. I sell a few. The most popular one is my new WellBlue 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 buy one, even if they have a regular water ionizer, because they will be traveling sometimes and will need it. However it’s not my personal favorite to 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 so much 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 20 years of using water ionizers for myself and my whole family] I can say that they are the single-best-thing I’ve ever used. 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.

Ionized Water, Kangen Water, Alkaline Water and Best Water Filters: Is Water Ionization the Same for all Alkaline Water Machines?

Not all alkaline water machines are the same. Some ionized water has a higher pH with a lower ORP, which is not good. Some water ionizers can provide lower, drinking levels, of pH with very high [negative] ORP. That is very good. Some alkaline water machines have more watts to get a higher/lower range of pH [for cleaning purposes. It’s debatable whether this is good or not. Raising the watts too high may not be the best thing to do, after all you do have valuable platinum coatings on the electrode plates…which you wouldn’t want to melt off if the plates got too hot. Some water ionizers have a mineral port, and I personally really like this option [although I don’t use it all the time]. The Enagic Company, of course, says Kangen Water is singularly the best alkaline water machine ever. But the Enagic Kangen Water ionizer is a water ionizer, just like the other alkaline water machines. The Enagic company attempts to persuade you [by coming up with a different name for the water, Kangen Water, for example] that Kangen Water is different than other ionized water. Kangen water is as different from other ionized water as any other water ionizer is different than the others. I would say that Enagic Kangen Water is better than many water ionizers, but not better than the  Vesta water ionizer, the Jupiter water ionizers, or the Chanson Miracle-Max and VS 70 water ionizers for getting a great, high, ORP per unit of pH. Also the new Vesta water ionizer beats Enagic in every conceivable way.

Also, 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. I don’t know of too many Enagic dealers that ever mention this though. When the strong-acidic-water setting button is pushed, a saline solution [which also contains bleach] is released into the water. This is a caustic solution. It’s also potentially caustic to the water ionizer to use 235 watts of power. [see Enagic’s warning page here:]
