Alkaline water is popular in the US because it offers amazing health benefits. However, bottled alkaline water is also one of the most expensive water types on the market.

If you don’t want to constantly pay for bottled alkaline water, you can choose to purchase a water ionizer device to produce your own alkaline water. Water ionizer is a home appliance that uses an electrochemical process called electrolysis to raise the pH of water into two streams; acidic water and alkaline water.

The best water ionizer is the Tyent UCE-13 Plus Water Ionizer, which offers acidic and alkaline water in the pH range of 1.7 to 12.5 pH.

Here are the most important factors to consider in a water ionizer device:

  • The pH range
  • Oxidation-reduction potential (ORP) range
  • The device flow rate
  • Filter efficiency (most water ionizers come with built-in water filter)
  • Product warranty (since water ionizers are very expensive!)

Tyent has been producing some of the top water ionizers since 2004, and the UCE-13 Plus model is by far the best product in the brand’s catalog. We particularly like this water ionizer because its 1.7 to 12.5 pH water ionization range allows it to produce extremely acidic and alkaline water.

The wide pH range of the UCE-13 Plus is mainly due to its thirteen mesh, hybrid, and electromagnetic plates that separate carbonates from alkaline minerals. As most water ionizers entertain only eight or nine plates, the electrolytic (this term refers to the separation potential regarding carbonates and alkaline minerals) capacity of the thirteen plates featured in the UCE-13 Plus is really something exceptional.

This Tyent device is no slouch when it comes to the molecular hydrogen boost it provides, either. It adds a minimum of 1.8 ppm (parts per million) of hydrogen to the water, which strengthens the mitochondria in our bodies, regulates ATP, and acts as an antioxidant in the long run. At -1,150 millivolts, the UCE-13 Plus offers good oxidation-reduction potential (ORP), which is simply not something you see in competitor products and it’s what makes it one of our favorites.

Furthermore, the UCE-13 Plus employs two-stage filtration to provide safe and clean water: a total carbon block that removes aesthetic impurities (color, taste, and odor) and chlorine, and a 0.01-micron ceramic filter that removes 99% of pathogenic bacteria like salmonella.

The UCE-13 Plus system features a colored LED display that allows you to pick the alkalinity and acidity levels you want, monitor the ionizing process, and see how many days until you need to replace its filters (usually once every six to nine months).

This device has six different alkalinity and acidity modes (three for each), as well as a turbo mode, which produces water from both ends of the pH scale, and a neutral mode (pH 7). It’s able to produce two litres of water per minute in each mode.

Of course, all these great features come at a high price ($4,795), but the brand also offers a lifetime warranty for its product. So, they guarantee it will serve you for years on end.


2. Tyent H2 Hybrid Alkaline Water Ionizer

Tyent H2 Hybrid Water Ionizer
  • pH range: 2.5 to 11.0
  • ORP: -1,150 mV
  • Molecular hydrogen boost: 1.8 ppm
  • Water options: 3 alkaline, 2 acidic, 1 turbo mode, and 1 neutral mode
  • Flow rate: 2 liters per minute
  • Warranty: Lifetime
  • Price: $4,250.00
Pros
  • Great ORP and hydrogen boost numbers
  • Efficient two-stage filtration process
  • Lifetime warranty
  • More affordable than the UCE-13 Plus
Cons
  • Its pH range of 2.5 to 11.0 might not be enough to meet your needs for water that’s extremely acidic or alkaline

Though entertaining a lesser pH range from 2.5 to 11.0, the Tyent H2 Hybrid Ionizer is no less impressive than the UCE-13 Plus. When you consider that it’s more affordable than the UCE-13 Plus, with a price tag of $4,250, it becomes evident that it is more than a worthy runner-up.

While its pH range of 2.5 to 11.0 might seem humble at first, it’s still able to produce alkaline and acidic water, be it for:

  • hygiene (extremely alkaline water at pH 11)
  • drinking and cooking (moderately alkaline water with pH 8.5 to 9.5)
  • haircare and face washing (acidic water that has a pH of 4.0 to 6.0), or
  • reducing germs (extremely acidic water at pH 2.5)

While the pH range of the H2 Hybrid is narrower than the UCE-13 Plus, it shares its ORP and molecular hydrogen boost capacities. Like our top recommendation (UCE-12 Plus), the H2 Hybrid can reduce oxidation by 1,150 mV and adds a minimum of 1.8 ppm of molecular hydrogen to the water.

Again, similar to its sibling, the H2 Hybrid uses two-stage filtration. While its ceramic filter removes pathogenic bacteria and sediment like mud, dirt, and clay from the water, its carbon block handles color, odor, taste, and chlorine. Thus, it provides alkaline or acidic water on demand and, of course, clean and safe water regardless of its pH level.

Unlike the UCE-12 Plus, the LED display of the H2 Hybrid is black and white, but it offers more or less the same features. It allows you to choose from 7 modes (2 for acidic and 3 for alkaline water, a turbo mode that produces highly acidic or alkaline water as well as a neutral mode), monitor the process of the system, and find out your filter’s life (six to nine months for both filters).

All things considered, this water ionizer is an excellent pick thanks to its lifetime warranty, amazing ORP and hydrogen boost numbers, and efficient two-stage filtration.

Thanks to its 9-plate electrolysis setup, the ionHealth Pro has quite a decent ORP of -950 mV.

Additionally, it adds a minimum of 1.6 ppm of molecular hydrogen to water to promote blood flow and healthy mitochondria.

Like the Tyent models above, the ionHealth Pro uses a two-stage filtration process to purify water. However, unlike the Tyent models, both of the filters employed by the ionHealth Pro are certified by the National Sanitation Foundation.

The first filter is a high-density felt film with a carbon block that can easily remove aesthetic impurities, chlorine, and total trihalomethanes. The second filter is another high-density film with antibacterial ceramic and calcium sulfate, which allows it to remove sediment and pathogenic bacteria like coliform.

While the first filter needs replacing once every one to two months, the second filter may last as long as eight months. Regardless, the ionHealth has a built-in LED display that warns you when to replace filters. It also lets you observe the process and pick from its different alkalinity and acidity modes.

Speaking of, the ionHealth Pro has four modes for alkalinity, two for acidity, and one for neutrality. While it provides two liters of alkaline water per minute, that number is three liters for the other modes.

Lastly, like the Tyent models we reviewed, the ionHealth Pro has a lifetime warranty.

Although its -850 mV oxidation-reduction potential (ORP) might seem modest compared to the other ionizers we reviewed, it’s still enough to provide water that functions as a potent antioxidant.

Furthermore, the Kangen Leveluk K8 has a 1.6 ppm molecular hydrogen boost, further reinforcing the antioxidant status of the water it produces.

Similar to the Tyent UCE-13 Plus, the Kangen Leveluk K8 has a full-color LED display with big icons and buttons, which eases the process for the elderly even more. This display allows you to pick one of the five options the device offers.

  • strong Kangen water at pH 11
  • Kangen water at pH 8.5 to 9.5
  • clean water at pH 7
  • beauty water at pH 4 to 6, and
  • strong acidic water at pH 2.5 to 4

Like all the other products on our list, the Kangen Leveluk K8 has filters that remove aesthetic impurities, sediment, and pathogens from the water.

That being said, the Kangen Leveluk K8 is easily the most expensive device on our list at $5,650.

Moreover, it can only produce one to two liters of water per minute, which makes it the slowest device we recommend.

Lastly, its 5-year warranty is poor compared to the lifetime warranties of the other products on our list.

Frequently Asked Questions

How does a water ionizer work?

A water ionizer separates acidic carbonate ions from alkaline mineral ions through its electromagnetically charged plates and ion-permeable membrane in a process called electrolysis.

Carbonates are negatively charged ions, while alkali minerals are positively charged, which is how the electromagnetic plates of a water ionizer can separate the two. Depending on your requirements, the device can adjust itself to produce alkaline, acidic, or neutral water by adding the right amount of ions to the water.

When the alkalinity of the water is raised, we call that a molecular hydrogen boost because the term pH refers to the “potential of hydrogen” in water and is measured by how much of the hydrogen in water is in a free state.

Why should I install a water ionizer?

You should install a water ionizer because the alkaline water it produces is healthier than neutral water. Several reasons make alkaline water healthier.

First and foremost, it protects human DNA from oxidative damage due to its oxidation-reduction potential. As oxidative damage is a direct result of air pollution, protection from it is crucial in this day and age. If you’re actively involved in sports, alkaline (or electrolyzed) water will improve your blood flow after heavy workouts

The standard American diet is full of acidic food products, like dairy, sugar, and meat, which may lead to acid reflux in the long run. Alkaline water prevents or reduces the adverse effects of acid reflux while also balancing the pH of our blood.

Lastly, there are claims that alkaline water promotes weight loss, helps with the immune system, and has colon-cleansing properties, all of which are necessary for a healthy aging process. However, we should note that there’s no comprehensive or conclusive research that supports this yet.

Of course, a water ionizer doesn’t only produce alkaline water but also acidic water. Although acidic water isn’t meant for drinking, it can help on other fronts. For instance:
Acidic water is good for bathing because it helps with skin conditions like refractory atopic dermatitis and eczema
Acid in water can help balance the pH of shampoos, preventing hair loss or breakage
Acids are an excellent way to fight hard water stains.

Which water ionizer is the most powerful?

The Tyent UCE-13 Plus is the most robust water ionizer on the market.
It has an impressive setup of thirteen electromagnetic plates, with excellent ORP (-1,150 mV) and hydrogen boost (1.8 ppm) numbers. Its strength is also reflected in its pH range since its 1.7 to 12.5 pH range is unmatched among competitor products.

Whether you want highly alkaline or acidic water or various options for each, the UCE-13 Plus will deliver. Its three water modes for alkaline and acidic water respectively, one for turbo (extremely alkaline or acidic water), and one for neutral water (pH 7), are a testament to this.

What is the average price of water ionizers?

A water ionizer costs between $4,000 – $5,000. So it’s fair to say that they’re luxury items.

Conclusion

Alkaline water is one of the healthiest water types as it offers protection from oxidative damage, promotes blood flow, maintains the pH of our blood, and helps with healthy aging. Installing a water ionizer is an excellent alternative to constantly paying for bottled alkaline water, which is one of the most expensive bottled water types.

If you want the most powerful water ionizer on the market that offers a variety of alkaline and acidic water modes, the Tyent UCE-13 Plus is the best with its 13-plate setup, -1,150 mV of ORP, 1.8 ppm hydrogen boost, and 1.7 to 12.5 pH range.

If you want to invest in a high quality ionizer yet don’t quite have the budget for the UCE-13 Plus, the Tyent H2 Hybrid shares all the specs of the former except for the pH range. It only entertains a 2.5 to 11.0 pH range.

If you’re in the market for a budget-friendly ionizer, the ionHealth Pro Water Ionizer is your best bet, as it costs $2,295.00.

Lastly, if you want a water ionizer with an easy-to-decipher LED interface and speech feature, the Kangen Leveluk K8 Water Machine is your best bet.
