Tyent ACE-13 – My Favorite

The ACE-13 was a gamechanger when it was first released, and it’s still one of the best water ionizers available today.

It’s actually MY FAVORITE!

This popular countertop model produces multiple levels of alkaline, acidic, and even neutral pH water for both drinking and non-drinking needs. It also filters and ionizes your water within seconds after activation.

Plus, you can save the runoff (which is typically acidic) and use it for tasks like washing your face and hair, cleaning your home, and gardening. No waste at all!

If you want to invest in an effective and luxurious countertop ionizer, the ACE-13 is your greatest bet.


  • Healthy molecular hydrogen-infused water with an Alkaline pH
  • 13 Solid/Mesh Hybrid plates
  • SMPS Plus Power Supply
  • Smartphone-inspired LCD screen
  • Various levels of alkaline and acidic water
  • Auto-Fill Quantity Selector
  • No-Stipulations Lifetime Warranty


  • Not the least expensive, but Tyent offers very affordable financing that makes each glass of water cost only about 6 a glass, which is awesome!
  • The company closes at 7:00 pm Eastern time, so if you’re on the west coast it’s best to call early.

Tyent UCE-13 – Celebrity Pick!

This under-counter model is Tyent’s newest release, and what a powerful machine it is! It’s the updated sister of the UCE-11 (which we reviewed before) with an increased number of plates for more efficient electrolysis.

The UCE-13 comes equipped with Tyent’s signature Hydrogen Boost technology, which maximizes the production of molecular hydrogen in your ionized water. The machine also boasts 55 fully adjustable water settings so you can customize it to fit your source water.

Also, this under-counter model fits snugly in your kitchen.

It’s no wonder it’s the Celebrity Pick!

We’re excited to talk about this machine in more detail, so stay tuned for our full review.

In the meantime, trust us when we say that the UCE-13 is worth every penny.


  • Hydrogen Boost technology
  • Streamlined space-saving design
  • Healthy molecular hydrogen-infused water with an Alkaline pH


  • Steep price
  • No AM/PM clock option

Jupiter Athena – No Frills

This is one of the lower-end ionizers on this list, and we only recommend it as a starter option if you’re broke and can’t afford to get financing (although there are some better options out there, which you can call us about). It’ll give you decent potable water for the price.

The Jupiter Athena can produce basic alkaline levels and acidic levels, meaning that you can get water not only for drinking but also for some other uses. It also sports an on-board flow control function to make it easier to adjust the flow of your water.

Additionally, IonWays offers a Lifetime Warranty, which seems great at a glance. However, there are a lot of stipulations in their warranty, so be sure to read the fine print because it could end up costing you a lot in the long run.

Overall, even if it’s not as powerful as other machines on this list, the Jupiter Athena is an acceptable machine for its price level.


  • Dual filtration system
  • Alkaline and acidic pH levels
  • Cleaning system
  • Good audio-visual alerts


  • Weak 5-plate electrolysis system
  • No safe default setting
  • No cleaning cartridge
  • Limited warranty
  • Small filters

Hydropathy Asio – Streamlined

If you’re looking for a budget option that produces ONLY hydrogen water without changing the pH, then look no further than Hydropathy.

While the Asio will work for some, we LOVE having the option to change pH levels, so it’s not on our favorites list, but we definitely think that there is a market for it.

Take note that this isn’t a water ionizer but a molecular hydrogen machine. That means its capacities are limited compared to the other electric water ionizers on this list.

What the Hydropathy Asio does best is filter your water and infuse it with high levels of molecular hydrogen. That means you’ll be getting the health benefits of clean alkaline water from an efficient unit, with alkalinity.

One cool feature is that the unit doesn’t produce wastewater, so it’s eco-friendly and energy-saving, too!


  • Modern stainless-steel design
  • Healthy molecular hydrogen-infused water
  • Easy-to-use Touchscreen Interface


  • No acidic water for Beauty water and other uses
  • No alkaline pH for healthy drinking water
  • 5-year limited warranty
  • High price for limited capacity

Tyent Edge 9000T – The Budgeter’s Lucky Charm

For those who are searching for a budget-friendly Tyent machine, the Edge is an awesome option.

It’s still the best in the 9-plate class of ionizers, producing a nearly 10-number pH range for drinking, cleaning, and many more. Plus, the dual Dialipure filtration system removes over 200 contaminants from your water.

If flow precision is a huge factor for you, you’ll love the Edge’s fixed water quantity options. No more accidental overflow in your kitchen.

However, since it has fewer plates than the ACE-13 and UCE-13, its capacity for electrolysis isn’t as strong. Still, Tyent continuously updates the technology no matter the level of plates, so you’d be getting a highly efficient ionizer if you buy an Edge.


  • 9 Solid/Mesh Hybrid plates
  • 6-9 month filter life cycle
  • Smooth stainless steel design
  • Automatic cleaning cycle
  • Power-saving functions


  • Only 9 plates
  • No smartphone-inspired LCD screen
