Expert Water Ionizer Reviews by Alkaline Water Plus

With over 30 years of experience testing and using water ionizers, I provide unbiased, expert-tested alkaline water ionizer reviews to help you make informed decisions. This section focuses on my personal reviews of the best alkaline water machines.

Water Ionizer Reviews Overview

These water ionizer reviews are organized alphabetically by brand for easy reference. Most are countertop units, with the AlkaViva Delphi H2 being a standout under-sink model. All ionizers provide alkaline water, but filtration and overall quality can vary significantly—some units don’t even filter heavy metals effectively.

AirWaterLife: Aqua Ionizer Deluxe Water Ionizers

The AirWaterLife and Alive Water Ionizers share a similar identity for some reason. The manufacturer is China. The Aqua Ionizer Deluxe water ionizer performs reasonably well, but has cheap parts.

The AirWaterLife ionizers have:

1. Some plastic parts, rather than stainless steel, indicate a lower quality.
2. The AirWaterLife ionizer requires a 15-second wait time before you pour ionized water. During this wait time, acidic water pours out of the top spout. This is a waste of both time and water. Younger children or anyone not paying attention could accidentally pour acidic water into their glass.
3. The filtration is not very good.

You can see my full review of the AirWaterLife Aqua Ionizer Deluxe here.

AlkaViva H2 Water Ionizers

The AlkaViva H2 Series of water ionizers tops the line in strength and performance. They use a brand-new, proprietary method of continuously cleaning the plates. This is even more worry-free than earlier models.

The water-cells are stronger than all the rest, too. This makes the H2 water ionizers the only water ionizers I fully trust for under-sink installation.

H2 Water Ionizers also use the best filtration, UltraWater filters. UltraWater filters are so advanced that they remove virtually every kind of contaminant, achieving a removal rate of up to 99.99%.

AlkaVivaAlkaViva water ionizers include the Melody-II, Athena H2, Delphi H2, and Vesta H2 water ionizers.

The AlkaViva machines use SMPS, switch-mode power supply. This allows water ionizers to operate at variable power levels. Customers program these machines to suit their needs and water source.

AlkaViva H2 water ionizers produce some of the highest levels of H2 molecular hydrogen antioxidants that I’ve seen.

AlkaViva’s limited lifetime warranties cover lifetime (parts) and up to 10 years (labor). These machines last 10-20 years, provided you care for them as directed.

All H2 water ionizers are excellent choices.

Ayana Water Vitality Round Disk Water Ionizers [AKA: Varunizer]

The Ayana water ionizer company gives false information about their Vitality Round Disk Water Ionizers. They are inferior to their competitors. Read more in my article about the results of my Ayana Vitality water ionizer testing.

The manufacturer is in Taiwan and imports into Canada. Ayana uses a sodium port, but it is non-functional. Customer support was of no avail.

Bawell Water Ionizers

Bawell is a Chinese manufacturer of water ionizers. The Bawell US representative has a cover address that goes to the UPS store in Boca Raton, Florida. Hiding one’s location is not a sign of trustworthiness for a company.

The Bawell Fountain water ionizer was able to produce alkaline water, but the ORP was poor. See full report and review of the Bawell ionizers.

Chanson Water Ionizers

Chanson Water Ionizers are compact, programmable devices, and they come with a 10-year warranty. The Chanson water ionizers have a flow-control knob and an extra-large mineral port. Other Chanson machines are the Chanson Miracle and Chanson Miracle Max. Chanson Water Ionizer Company in Taiwan has been manufacturing water filters for over 30 years.

Because the filtration inside the Chanson ionizer is inadequate, they recommend using an additional filter. They also recommend using a citric acid cartridge to wash it internally every 3 months. They may void the warranty if you fail to do this.

Chinese Water Ionizers Reviews

Chinese manufacturers use poor-quality parts. There is insufficient quality control in the Chinese mainland.

I recommend buying your water ionizer only from countries that have good manufacturing controls. In Korea, there is the KFDA, and in Japan, there is the Japanese Ministry of Health.

I investigate the manufacturers of water ionizers. I review their certificates before listing their water ionizer on my site. Chinese certifications aren’t trustworthy, though, because the inspectors take bribes.

Enagic Kangen Water SD501 Water Ionizer and the K8 Water Ionizer

The Enagic SD501 Water Ionizer is a strong ionizer. It uses a constant 235 watts of power, which activates its massive plates. The Enagic K8 water ionizer is very similar to the Enagic SD501 in terms of quality and testing results.

High watts help the Enagic Kangen water machine achieve a relatively fast flow rate and a wide range of pH levels. However, there is significant stress due to the high power requirements and the corrosive nature of salt.

If you use the “strong acidic” setting too frequently, it hurts the machine. Additionally, you must flush the ionizer thoroughly after using sodium, as it can damage the machine. There is a warning about this on the Enagic site, but the company has not fixed this problem.

The Enagic machine must also produce a powerful flow to stay cool enough. This reduces filtration effectiveness. When the flow is insufficient, a voice alerts you to increase the water flow. The ionizer will not ionize when the flow rate is too low.

The Enagic Kangen Water ionizer typically lasts 5 years or more, unless the plates corrode or scale up. Kangen Enagic Water Ionizers Pros and Cons

Impart Group: Excel Water Ionizers

Impart Group stems from the same company as Enagic. The Impart Group engineers disagreed with Enagic’s “bigger is better” ideas. This led to a split within the company.

Impart water ionizers use 5 large plates. Excel IE-900 performs as well as the Enagic SD501, but at about half the cost. The MX-99 is the newer model, but it is similar to the Impart Groups water ionizers in terms of sound engineering construction.

The plates are subject to abuse if you use the “strong acidic” setting too frequently. Also, if you don’t flush the ionizer properly after pouring strong acidic or potent alkaline water.

Impart water ionizers come with a 1-year full parts/labor warranty.

Ionia Water Ionizers Reviews

Ionia is the oldest and most renowned water ionizer manufacturer in Korea. Ionia water ionizers test up with the higher-priced machines.

Ionia produces several brands, including Jupiter, Emco Tech, Nexus, and Smart water ionizers.

The Nexus brand engineers collaborate with hospitals in Japan and South Korea.

The scientists working on the Ionia team are among the most influential. They conducted numerous clinical trials, helping to validate water ionizers and the benefits of alkaline ionized water.

Ionia produces highly efficient water ionizers that cover a wide range of pH and ORP values. Ionia’s water ionizers are very well-built.

IoniaSuper-S12 Water Ionizer is like buying two water ionizers in one. It has two water cells and a saline injection port, which work together to create all levels of ionized water with ease. The Super-S12 also has ultra-fine .01 dual filtration.

Jupiter Water Ionizer Reviews

Jupiter water ionizers are well-built, easy to use, and come with lifetime warranties. All Jupiter Water Ionizers have outstanding plate design and efficient plate cleaning.

The Jupiter Athena, Vesta, and Ultra-Delphi water ionizers have been upgraded to H2 Water Ionizers. They are capable of super high levels of H2. 

Jupiter also has access to the UltraWater filters, which are considered the best water filters available. Jupiter water ionizers come highly endorsed by scientists working in the field of ionized water. 

KYK Water Ionizers

KYK water ionizers are average in performance and filtration. KYK used a poor business associate and now no longer imports into the US.

LifeIonizers Water Ionizers Review

I used to sell Lifeionizers until I found reasons to distrust them. Their machines had substandard filtration capabilities, and they didn’t compare well with other water ionizers. Lifeionizers used to literally harass me at a point when I began to question their quality.

The Life Ionizer machine has poor filtration, which is why the Life company recommends using extra pre-filters. They provide you with your first set free, but after that, you must pay to replace them annually.

The machines use a dipping and baking process to coat the plates with platinum. This is an amateur method. The plate cleaning is also an amateur acid wash. You can expect diminished performance over time.

They offer a trial period, but you pay 15% restocking and the costs of shipping if you decide you are not satisfied with your purchase.

The warranty becomes void if you don’t use the citric acid cleaning 3 times per year.

Smart Water Ionizers

Smart Water Ionizers are of the highest quality. The Smart 9P features 9 plates and can produce up to 1.5 ppm of molecular hydrogen. Its power ranges up to 235 watts and has an SMPS electrical supply.

The Smart water ionizers use continuous cleaning, as opposed to the traditional automatic acid wash cleaning of the X-Blue.

Alkaline Water Plus imports the Smart 9P, allowing us to pass the savings on to our customers.

Tyent Water Ionizers

Tyent’s water ionizers rank in the average range for a water ionizer. For as long as I’ve known them (over 15 years), the Tyent company has consistently employed the same numerous misleading sales tactics. They are by far the worst offenders (and wouldn’t you know, their owner is a formerly well-known master of deception). See more on this page: Beware of Fake Awards and Water Ionizer Reviews From Tyent, Life, Enagic, and AirWaterLife

Tyent uses a Korean manufacturer (Taeyoung E & T Co., Ltd.). The quality of construction is about average. The plastic faucet on the Tyent undersink water ionizer is a poor feature.

The Tyent water ionizers use amateur acid-washes and an amateur plate-dipping process.  With a Tyent water ionizer, it is recommended to perform a citric acid cleaning approximately every 3 months.
