The Athena H2 water ionizer is one of the newest, state-of-the-art, best water ionizers.

  • By internal switching from AC to DC the H2 water ionizer is a powerhouse for the production of H2 (antioxidants).
  • With the Athena H2 water ionizer you get the power of H2 antioxidants with every level of pH you select.
  • The Athena H2 ionizer is a very sturdy water ionizer.
  • The DARC cleaning system keeps the plates in like-new condition for the life of the water ionizer.
  • H2 water ionizers are so long-lasting they are the only models I recommend for under-sink installation.
  • All AlkaViva alkaline water ionizers come with lifetime warranties.
  • The AlkaViva Athena water ionizers also use UltraWater filtration. There is no better filtration in the world than the UltraWater filters used in the AlkaViva Athena H2 water ionizer. The filters produce the cleanest water, compared with all other water filters.

The Athena H2 the best water ionizer I have found in many water ionizer comparisons. It gives the highest levels of H2 (molecular hydrogen) and ORP per unit of pH of any other water ionizer.

Why are H2 molecules so important?

The tiny size and solubility of H2 makes it the only free-radical neutralizer capable of passing through cell membranes. It even passes through the blood-brain barrier. Inside the cell, where free-radicals do the most damage, the power of molecular hydrogen becomes a literal life-saver.

Distinctive Features of the AlkaViva Athena-H2 Water Ionizer

  • SmartDesign: Seven high grade, technologically advanced, pure platinum coated titanium plates! The seven, advanced, electrodes are solid plates. The "SmartDesign" of them is that they very efficiently produce the best ORP per unit of pH of any water ionizer.
  • More Settings, 5 Alkaline Settings (not just 3 or 4): Five alkaline settings produce ionized water for drinking. There are no chemicals used to make even the strongest levels of alkaline ionized water in the Athena H2 water ionizer. Note: Always start drinking on the lowest alkaline level and move up if and when ready.
  • Powerful Hydrogen Antioxidants Generator: The production of molecular hydrogen, or H2, requires advanced technology, which the H2 water ionizers have. The Athena H2 water ionizer uses advanced and patented Hydrogen Infusion Technology, which enables optimal levels of molecular hydrogen (H2 Antioxidants).
  • Hydrogen Infusion Technology specifically optimizes the infusion of Hydrogen antioxidants into the water and performance of the water ionizer. This technology is very new and unique to the H2 water ionizers.
  • Best negative ORP: The molecular hydrogen or H2 powerhouse design contributes to the ORP of the Athena water ionizer. ORP is oxidation reduction potential. It's a very important feature that the ORP, per unit of pH, on all alkaline settings is exceptional!
  • Continuous-Cleaning: Fully automatic continuous-cleaning means that your H2 water ionizer automatically cleans all the time. It will maintain it's peak performance throughout the life of the water ionizer. 
  • The competitors have only intermittent, cleaning. This could allow for some calcium build-up on the plates because it's not continuous.
  • Calcium on the plates makes them less able to ionize at their maximum. It is a scientific principle that platinum catalyzes [speeds up] electrolysis. But, to do that the platinum must be in direct contact with the water. So, even the thinnest film of calcium on the plates can inhibit that water ionizer's potential to ionize fully and efficiently.
  • With the Athena H2 water ionizer the cleaning is automatic, in background, and continuous - 100% of the time. You never have to wait, and your H2 water ionizer always gives you the maximum amount of antioxidants in your water. 
  • AutoAdjust for optimum pH levels. All H2 Series water ionizers have the AutoAdjust feature. This allows the machine to adjust the power at optimum levels for your source water. You can set and forget your power settings with AutoAdjust.
  • High Quality, Patented, Ultra-Water Filtration. The Athena H2 Water Ionizer's filtration is going to give you pristine clean water!
  • Real-Time Flow Control: Get maximum flow-control with the new Athena H2 water ionizer.
  • SMPS power supply is the most up-to-date, latest version
  • Ongoing self-diagnosis and control with a Micom (mini-computer) on-board! The Micom [miniature computer] System controls every operation of the Jupiter Athena water ionizer to improve performance.

What is SmartDesign?

SmartDesign electrodes are state of the art and super-efficient at all power-levels, even the lowest power-level.

After extensive research, the H2 Water Ionizer engineers found that higher power density reduced the amount of H2 in the water.

To increase the amount of H2 dissolved in the water use a lower density of power. This is how SmartDesign originated.

In addition to better performance, running lower power puts less stress on the plates, which leads to increased durability over time.

SmartDesign electrodes are the most advanced, solid plate design of all water ionizers. They are electro-plated and optimized specifically for highest performance and efficiency.

Advanced Protection Against Hard Water

Hard water can harm a water ionizer, and often your warranty doesn't cover it. But the Advanced design of the H2-Series water ionizers protects against hard water better than any other water ionizer. For hard water protection, the Athena H2 is in a class of its own.

Advanced UltraWater Filtration

UltraWater filtration is a great invention. No other filters can purify the water in such a healthy way.

Even reverse osmosis and distillation misses some contaminants, like Fluoride, which have a low atomic weight.

UltraWater filters lab tests prove they remove up to 99.999% of contaminants, regardless of atomic weight. Patented dual filters consisting of 0.1 micron filters combine with space-fiber technology to efficiently filter almost any tap water.

The two filters do a complete job of filtering your water properly. These advanced filters also have anti-scale ports built in.

The filter life change indicator lets you know when it’s time to replace your filters.


Filter-Changing Instructions

All filter systems develop a sort of suction (resisting the release of the filter). You will have an easier time with filter replacement in the future by following these steps:

  1. Shut off the water flow.
  2. Turn on the alkaline flow (as if water would come out). This releases pressure or suction in the line.
  3. Replace the filters only now that the pressure has been released.
  4. One other thing is the little electronic connector should be removed first, before removing the old filter. Then clip it into the new filter first, before inserting the filter and turning it into place in the filter port.
  5. AlkaViva also recommends rubbing food grade lube like olive oil, coconut oil, or any other type of food grade lubricant on the o-rings on the unit where the filters go.
  6. If you still have any difficulty, use a slight tilt back and forth while pulling up on filter.

Also, make sure to order your filters from us to make sure you get the right ones. I can't tell you how important it is to get the right replacement filters.

If you ever have problems with this or anything else, please call us or email right away. We will make sure you get the support you need quickly and efficiently.

H2 Water Ionizers are Strong on the Inside

H2 water ionizers are very strong water ionizers and can hold up to considerable internal pressure. That's why this is the only brand of water ionizer we recommend for under-sink or other kind of pressurized installation.

ALKAVIVA Athena H2 Water Ionizer Warranty

The parts within the Athena H2 water ionizer and all AlkaViva water ionizers are of fantastic quality. They can last a lifetime.

It's very rare that any of our water ionizers would have a defective part. But for your protection, all AlkaViva water ionizers have limited lifetime-parts/labor warranties.

  • We will register your water ionizer for its AlkaViva Lifetime Parts & 5-Year Labor Warranty for you.
  • Also, for no extra charge to you, we will increase the "5-Years" of Labor to 10-years. Just say "upgrade warranty to 10-years labor" in the comment section of the order form.

Note: A water ionizer is a life-long investment in your health.
