Multiple Water Ionizers Comparison

Comparing water ionizers & water filters

Water ionizers comparisons made ​​by independent government laboratories Silver State Laboratories, U.S. EPA certified laboratories (U.S. Environmental Protection Agency) based on tests conducted on the multiple water filtration – ionization devices.


Comparing water ionizers


There are various websites comparing alkaline water ionizers. Each provides their own “ratings” and a version of a test video which can be faked >>> Read Here about fake water ionizer tests .

These “comparison” sites try to make you think they are unbiased, but in reality these “comparison” sites are really designed to sell you their brand of water ionizer or the brand they get a kick-back from. They are not unbiased and objective – and they hide this from you, even masking who owns the website They provide few real FACTS that you can verify. They only focus on pH, ORP and the size of the electrodes. There is so much more to consider when deciding which water ionizer is a better choice for your personal needs – click !

Here is the logical way — the informed way — to compare water ionizers:

How long have they been in business? Can you locate or verify them?
What type of certifications do they hold? Are they an assembler or manufacturer?
What is the track record of the product in the United States?

Who are they? How long have they been in the business?
Customer Support? Service Center?
Warranty? Guaranty?
Water expertise? Can they help solve YOUR water quality issue?

About pH and ORP performance .What type of water ionizer test can you trust? Is extreme pH & ORP really healthy?
Debunking the that myth of “bigger is better”?

Understanding the importance of different cleaning systems in keeping plates clean from hard water scale deposits , thus keeping performance and ensuring your water ionizer doesn’t break .

List of significant features and brief explanation of each

Other considerations apply when deciding the best water ionizer for your specific needs

The Solution: Consider the FACTS!

This site is different.

We do not hide who we are or what brand we want you to buy.

We want you to know:

  • THE most important fact: Emco Tech has been the LEADING  brand of water ionizers in the WOLRD for over 30 years.
  • We have MORE experience, MORE expertise and MORE years in the water ionization business than ALL OUR COMPETITORS COMBINED.
  • We provide you FACTS that you can believe, check in and trust. We provide verification for all our affirmations.Any misunderstanding or questions you might have,please CONTACT US – chat,mail , phone!
  • There are other important considerations when buying  quality water ionizer, rather than simply pH, ORP and electrode size.
  • We are the Associated AlkaViva Dealers and we want you to buy Emco Tech and AlkaViva!

    We didn’t always sell IonWays products. Collectively we have offered other top brands including Toyo, AlkaBlue, Nexus, EnagicTM, KYK and more. Nevertheless, we are all now convinced that Ionways ionizers are simply the best available. 

    As importers, we have over 15 years of experience and expertise in selling alkaline water ionizers and providing top-notch customer service. Collectively including our dealers, we have well over 200 years of experience. Some of our competitors have been in business for only a scant year or two, or offer water ionizers that have not stood the test of time. We would like to offer you the opportunity to benefit from our collective experience and our common conclusion: you can trust IonWays and Emco Tech to deliver top performance, quality and value year-in and year-out, long after many Johnny-come-lately’s have disappeared.


Search no more. The facts are in: Emco Tech is #1.

Compare 2016 Alkaviva H2 Water Ionizers with Enagic, Kangen, Life Ionizers and Tyent Ionizers

We have tested the latest Alkaviva H2 water ionizers against the leading models from Enagic/ Kangen, Life Ionizers and Tyent water ionizers and the results speak for themselves.

The results categorically show that the latest Alkaviva H2 water ionizers outperform all other leading water ionizer brands in the key water ionization performance metrics – pH, ORP and diatomic molecular hydrogen H2 in ionized water.

The new Alkaviva H2 water ionizers use the latest technologies(SMPS & AutoAdjust, DARC II electrode autoclean,RealTime water flow control , H2 infusion Technology)  available  built upon 30 years of manufacturing experience that is more efficient and durable ensuring a long plate life and water ionizer life,  current water ionizers from brands such as Life ionizers use outdated technology requiring larger electrode plates to perform adequately which degrade over time and require excessive electrical power to operate(witch may lead to faults).

Alkaviva have dedicated extensive research into developing not only the best water ionizers but the best water filtration technology – Ultrawater. Other brands use cheap carbon and vitamin C filters that do a poor job of removing many common impurities such as fluoride, chlorine, hormones, VOC’s and heavy metals. Ultrawater filters have been tested and certified by EPA governmental lab  to removes all impurities by up to 99.9%.

Unfortunately there is a considerable amount of false claims and inaccuracies made on some water Ionizer manufacturer’s websites about the water ionization performance of their water ionizers versus other brands. We have been selling Alkaviva/Jupiter products for over 14 years and know the performance of the AlkaViva water ionizers  is second to none 

In terms of reliability, water ionization performance, the 2016 Alkaviva H2 water ionizers are the best water ionizers for sale in the world at the moment.

Foot Note: Comparing Transformers to SMPS Power Supply Systems.

A switched-mode power supply (also called SMPS) is an electronic power supply unit which differs from the more common linear, transformer type power supply. Each type has advantages and disadvantages. For example, while the SMPS power supply is lighter weight and typically less expensive to manufacture, it has been shown to respond more slowly and be less stable overall than the Transformer system. One clear advantage of SMPS has nothing to do with its electrical performance and this is that its lighter weight results in lower shipping costs.

While some water ionizer manufacturers choose to employ SMPS for use in water ionizers, comparative research by Emco Tech into specific water ionization applications indicates an overall lack of stability and long-term reliability in the systems currently available. Following are the comparative results of EmcoTech’s research on SMPS versus Transformer power supplies in water ionizers, in a residential setting:

Much has been made in the internet marketing for water ionizers using SMPS. One example would be that SMPS can adjust the water ionizer’s performance to your water quality. Technically this would require an extremely fast power supply response time. Based on Emco’s research you can see that SMPS does not produce. While SMPS is employed in some electronics due to the weight and cost advantage, transformers remain the most prevalent, durable and most stable power system in home electronics. EmcoTech utilizes a transformer based platform in order to assure stable, long term and consistent power supply – and reliability for every customer.

Don’t just Buy the Advertised Features – Buy the Real Value!

We want you to make an educated choice and have assembled essential information to help you determine the best water ionizer for your budget and needs.


AlkaViva understands there are quite a few competitors in the marketplace and important differences between the various brands of water ionizers.

Unfortunately, tricky marketing and questionable sales tactics are often used to avoid answering important questions such as who is behind the water ionizer you buy and how reliable and proven will your water ionizer be.

The charts in this article show technical and basic differences between multiple brands of water ionizers and between water ionizers in as unbiased a manner as possible. It may not be as “interesting” to read as on other sites, but hopefully will provide you with essential and accurate information.

Comments/ Helpful Advice

The details in the charts are accurate to the best of AlkaViva/ IonWays knowledge.

For more information on any brand please CONTACT US

1. There are a few very misleading water ionizers comparison sites now on the internet. These are not true comparison sites but sites put up by an importer to make sales by showing dishonest or misleading information.

It pays to check the “facts” and talk with internet dealers that sell many brands for their opinion of what is best and the most reliable. AlkaViva IonWays tries to hold a high ground, but will provide independent comparison test results from a truly Independent Laboratory upon request.

2. Emco Tech (previously Jupiter Science) is the only Manufacturer of water ionizers in Korea and one of only a few in the world.

All Jupiter Science cells are manufactured in Japan by Jupiter Science’s own R & D. Department.

Other companies are simply assemblers (buying parts from elsewhere) with no ongoing Research and Development.


3. Copy models from China/Taiwan are beginning to show up in the USA and EU.

Be careful of products that have not been made for the USA or EU market and have no track record here.

These models can disappear as quickly as they have appeared, leaving customers without any backup service, filters or parts.

Emco Tech has been making water ionizers since 1982 and produces 90% of all water ionizers in Korea with a production plant capable of over 100,000 units a month.

4. AlkaViva Vesta. Melody, Aquarius, Athena and Delphi water ionizers are still the ONLY water ionizers to always give alkaline water (even when cleaning). This patented system means that there is no waiting, no risk of drinking acid water by mistake and also means that scale build up on the plates is minimized -> ALWAYS TOP PERFORMANCE & INCREASED DURABILITY.

5. ** Most water ionizer units use only genuine Platinum Titanium. This is because Platinum is by far the most effective and stable element for water ionization.

Some models made in Taiwan(i.e:CHANSON) are using Platinoiridium or Platinum mixed with Iridium. They don’t use platinum titanium because platinum titanium is 7 times more expensive than iridium. The Japanese and Korean governments do not allow any company to sell iridium for drinking water applications because it is bad for your health. The EP units made for the US market do not use iridium while the same models in Taiwan/China do use iridium.

Also there are new models on the market using ‘white gold’ for their plating. This is very misleading as there is no such thing as “white gold” since gold is always yellow. “White gold”, in fact, is actually an amalgam and contains at least 62% silver and other minerals. Platinum is about $1250 an ounce while Silver is about $12 an ounce. Obviously all the Japanese manufacturers and Jupiter Science etc would use “white gold” if it was any good.

Some companies use cheap plates that are dipped in iridium instead of been baked which is a more expensive and effective method.

Emco Tech is the ONLY company in Korea that manufactures their own plates (in Japan).

ALL OTHER companies are just assemblers importing their plates from Taiwan or China.

6. ** Enagic® models are so expensive not because they are better than all the other brands at a lower price, but because Enagic® needs to markup prices in order to be able to pay out 8 levels of sales representatives. Ask why their water filter replacement is well over $100 and ask to see their compensation plan. For further comments please see our

7. A few manufactures make a lot of profit from replacement filters.

While most brands have reasonable water filter prices there are some that don’t. But regardless why buy an water ionizer if the water filter does not remove most of the contaminants in the water?

We now offer for FREE our ULTRAWATER filters, in addition to the standard factory water filters, that will remove ALL known water contaminants (including Chlorine, chloramine, Fluorides, pharmaceuticals, nitrates, etc) with an OUTSTANDING 99.9% accuracy -lab testing proof available

Ultrawater offers the BEST possible water filtration from ALL known water contaminats with an outstanding precision of 99.9% , including chlorine, chloramines nitrates, fluoride ,  etc), but WITH healthy, natural minerals to pass (we even remineralize water)(as opposed to dangerous distilled & purified water (i.e.Reverse Osmosis) our water is a fountain of HEALTH, detoxifying your body without depleting it from essential minerals

8. Some manufacturers are employing larger plating and claiming they are superior. They hope to fool the consumer into thinking “bigger, is better”.

With electronics quite the opposite is true (consider how the radio, camera, computer and TV have evolved). Effective conductivity is the primary determinant – NOT electrode size – of effective delivery of voltage into the water needed to create electrolysis. The larger electrodes draw 3-4 times more power DECREASING the electrode life with NO additional benefit to the water quality. See our report on “Why Bigger is Not Better” Here

Generally the larger electrodes have poorer conductivity due to inferior plating processes or the grade of materials, so they have to be larger.

Similar things  can be said about extreme pH or ORP values

As opposed to other brands that focus on producing wide range of pH & ORP, though ALL our water ionizers can and will produce ionized water with wide range of pH & ORPALL our water ionizers are designed to optimally ionize your water – with a unique history of over 30 years research and experience , collaborations with hospitals , medical centers, specialists and researchers,we think that what nature creates should be a reference point .NATURALLY occurring alkaline and ionized water is NOT generally over pH 9 nor does it have artificially high – ORP. We know – we went to Vilcabamba, Ecuador to meet with the people in the Valley of Longevity and tested their water. If interested, please ask for our FREE DVD on this trip contact us or leave your mail address( we will not share it with anyone)

Experts do NOT recommend drinking water over pH 9.5 -such as Dr. Theodore Baroody (author Alkalize or Die), Dr. Robert O. Young (The pH Miracle), Sang Wang (Reverse Aging) and the Korean FDA plus Japanese Ministry of Health.

9. The BionTech is different from other water ionizers in that it is a batch system that uses 4 liters of water to produce 2 liters of alkaline water about every 15 minutes. The disadvantage is that it is slow to make alkaline water and needs to have the water added in manually. Advantages is that you can use it anywhere there is power and you control your input water. It is also capable of making super acid water of 2.5 pH.

10. When looking at what brand to buy look also at the level and quality of ongoing support you will be getting.

This point can not be emphasized enough. In the last three years alone, approximately 8 new water ionizers manufacturers have come and gone in the market

With Emco Tech you buy with absolute certainty that your company will be around to support you – long after the other Johnny-come-latelys have left some people high and dry.
We will be there for any ongoing support.

Emco Tech`s combined 35 years of experience and track record is UNmatched. Period.

11. By US tested we mean that the company have been selling in the USA for at least one year. It takes a number of years to show that a water ionizer is reliable (less to show it is not).

Tyent, for example, after only one year, is now longer selling the first model they imported into the USA and now sells a new unproven model – the MMP7070.

12. We do NOT recommend models that use UV lighting as a means for moving bacteria or viruses. UV light has to shine through a clear surface but in time these surfaces tend to become opaque or dirty (especially where there is hard water). Also the UV bulb may stop working and UV light may not work well with fast water flow. In comparison anti-bacterial filters will always work at optimum strength as long as they are replaced in time. All water ionizers that use water filters have a water filter counter inbuilt.

13. Some new companies from China, Taiwan and Korea claim to have an inbuilt ORP meter. Although a good idea this is still only at this stage gimmickry. It is very hard to get an accurate ORP reading and an ORP meter needs to regularly recalibrated and cleaned (since its points quickly get oxidized). In our tests using water ionizers with inbuilt ORP we found that the readings were very inaccurate and misleading when compared to the results from a proper ORP meter.

WARNING: What you See may NOT be What you Get

Emco Tech (Jupiter Science) water ionizers have been sold in the USA since 1995 and recently the great success of AlkaViva/ IonWays/Ionlife as the industry leader, has resulted in many new water ionizers

Because new players have little to lose and possibly a lot to gain it is very tempting to put up a good looking site that compare water ionizers, then manipulate, cover-up or not reveal facts and figures to fool the unwary.

AlkaViva has been, and is, happy to let our customers and dealers speak for themselves.

But there comes a time when it is necessary to get involved on another level.

As an example of what is NOT a true, independent site, comparing water ionizers, please go to

Is it obvious who put up this site and for what purpose?

Are you told this is not an unbiased compare water ionizer site (it is owned and run by Life Ionizers)?

And why are the only links on the home page to Gold Fox (a non-competing low end model) and Kangen (a not for retail/wholesale MLM company)?

Next click on the link that goes to the comparison chart.

Did you expect or hope that the information here would be unbiased and accurate?

And do you see here that Life Ionizers has changed “manufacturer” three times since 2007?

Now please click on the “Independent” Comparison Lab Tests button

These compare water ionizer tests were apparently run on hard water (where the pH is high to start with) and apparently show the Athena hardly able to change the pH at all, unlike the Life Ionizer unit that gets an impressive 10.9 pH.

Well, we know these results are not true because:

  • The Athena is our top selling water ionizer and in government certified tests shows it outperforming other brands -See EPA-certified-Lab-Report-water-ionizers – CLICK HERE.
  • AlkaViva would not be in business as the leading water ionizing company with over 600 dealers in USA plus Agents in about 28 other countries if we did not get great results in pH, ORP and reliability. We know AlkaViva water ionizers compare well to any other brand and with the patented DARC cleaning system we know our water ionizers will keep performing like new for many years after others have failed due to scale buildup and breakdown of the plates etc.
  • The person in the white coat was employed by Life Ionizer in 2008 as a salesman and was employed with no experience in water ionization and with no scientific qualification.
  •  Do a web search for dealers that sell Emco Tech models AND other models.  Ask them what they think of Emco Tech and what results they have achieved.

Now read on … this gets interesting!

So, on July 22, 2008, we decided to call Aquatic Consulting & Testing Inc to see how these test results that compare water ionizers were obtained. The technician, we spoke to, knew about the water ionizer tests and told us that he was never sent any water ionizers!.

Instead what he was sent were water samples in the mail, by a dealer of Life Ionizers, with the name of the water ionizers on the outside!!! He did what he was asked to do and now what you see is what Life Ionizers wants you to see.

Another example of a bogus compare water ionizer site is  All the “information” on this site was put up by the importer selling the unit. The guy in the video was Rob Gray of Tyent. And guess which unit “appeared” to perform the best?

Please notice

a) how the “tests” are performed with completely un-credible and non-scientific methods and protocols and

b) how answers to obvious questions are ignored such as, “How old is the unit?”, “What was the water source?”, “What levels are used in testing?” and “What type of meters are used and are they cleaned and calibrated?” Etc.

Also these compare water ionizer sites ignore a very important issue; who are you buying from?

Emco Tech has been making water ionizers as long as any company around (28+ years) and selling water ionizers into the US market longer than any other company (14+ years). We provide better service, more post sale tools like installation and user DVDs, and have excellent customer service and manuals. We have already been and will continue to be around a lot longer than our competition.

Let’s shift the conversation about comparisons to include ALL the salient questions. AlkaViva water ionizers perform extremely well and will continue to, long after others have built up tremendous scaling, and we provide the best certainty and service.

So when you look at videos that show a man in a white lab coat testing water ionizers or see performance charts or read about this company being the biggest and best then please ask questions and check around. We will happily provide evidence to back up everything we say on our site.
