Features of the H2 Series Water Ionizers
- H2 water ionizers use UltraWater filters. UltraWater filters are tested in EPA-certified U.S. labs and are the best filters on the planet. In the lab testing, all 249 contaminants tested were reduced to 99.9% contaminant-free. No other filters have been tested so rigorously.
- The electrical efficiency is ensured with H2 water ionizers’ AutoAdjust Advanced Power Supply. What AutoAdjust does is modulate SMPS power in a way that pulsates. This pulsation excites the highest performance while also causing no damage to the electrodes. Other types of electrodes, which claim to use 800 watts of power to the plates, will deteriorate those plates over time, whereas the AutoAdjust plates won’t.
- H2 Infusion Technology: It’s not just the plates, it’s the membranes. The H2 Series Water Ionizers utilize proprietary membranes between each of the Smart Electrodes to maximize the amount of H2 (molecular hydrogen). This one feature makes all the difference in H2 water ionizers’ ability to infuse hydrogen.
- New and Improved Automatic Continuous-Cleaning: There is no comparison between water ionizers that use continuous-cleaning and those that don’t. The H2 water ionizer employs a highly advanced form of continuous cleaning that is more effective and reliable than any other.
- Innovative Electrodes are used in every H2 water ionizer. These electrodes are constructed from the highest quality Japanese titanium and platinum, and through precise engineering, they have become the most efficient, longest-lasting, and highest-performing electrodes in the industry.
- Protective Circuitry: The diagnostic computer circuits within H2 water ionizers are designed to protect your ionizer from harm while bringing the highest, most state-of-the-art performance.
- Cell Safe Technology: The BPA-free water cell in the H2 water ionizers is designed to withstand up to 90 psi of pressure. This means the risk of water cell rupture is very low with an H2 water ionizer.
- One Touch Convenience: The H2 Water Ionizer is easy and uncomplicated. It remembers your last water level selection, and with one touch, you can pour the exact same water, time after time, unless you change it.
- Flow Control: You can use the LCD screen to view the flow rate, allowing you to adjust it to your exact specifications.
- AlkaViva water ionizers hold reputable certifications, including UL, CSA, ISO, CE, RoHS, and Korean FDA, which support their safety and performance claims.
- AlkaViva has been in the U.S. market since roughly 2002, with experienced support staff and continuity in service—not a fly-by-night operation.
Major Comparison Points All Favor AlkaViva
For comparison, here is a summary of the most relevant points of a water ionizer. Based on these points, AlkaViva compares favorably to the highest-priced water ionizer brand, Enagic.
Filtration Performance
AlkaViva H₂ Series (UltraWater Filtration):
- Uses proprietary UltraWater filtration, independently tested in EPA‑certified/NELAP labs, removing up to 99.9% of up to 249 contaminants—including heavy metals, pharmaceuticals, pesticides, VOCs, and more.
- Vesta H₂ and other H₂ models utilize dual or 13-stage filtration systems, delivering exceptionally pure, yet mineral-retaining, water.
- Comparative testing shows AlkaViva’s filters reduce virtually all tested contaminants to 99.9%, while Enagic’s Kangen filters are only tested for and certified to remove chlorine taste and odor (WQA Gold Seal / NSF).
Enagic Kangen Series:
- Includes basic carbon-based filters, typically certified only for removing chlorine and its odor/taste—not broader contaminant removal.
→ Verdict:
AlkaViva H₂ clearly offers far more comprehensive, independently verified filtration than Enagic’s Kangen units.
Hydrogen (H₂), pH & ORP Performance
AlkaViva H₂ Series:
- Incorporates H₂ Infusion Technology, which combines custom ultrasonic-welded membranes and Smart Electrodes (platinum‑coated titanium) to boost hydrogen generation, especially at drinkable, moderate pH levels.
- Performance benchmarks show Vesta H₂ achieving:
- High-alkaline pH (10+) and ORP
- H₂ levels are high too. (see videos below)
Enagic Kangen Models (e.g., K8, SD501):
- The reported hydrogen output is lower than for all price ranges of AlkaViva H2 Series water ionizers, even the Melody II, and the ORP is also less intense.
- The comparison indicates that Vesta H₂ significantly outperforms K8/SD501 in both hydrogen production and antioxidant potential.
Engineering Advancements & Maintenance
AlkaViva H₂ Series Highlights:
- SmartElectrodes with advanced design for efficient, longer-lasting performance.
- The DARC II (Double Automatic Reverse Cleaning) system automatically cleans the electrodes with each use—helping to sustain performance and longevity.
- The AutoAdjust Power Supply (SMPS) dynamically adjusts power delivery for optimal and efficient performance.
- Flow Control Systems and RISC circuitry—for precise flow rate selection and self-diagnosis protection.
- Robust warranties are available, including lifetime parts coverage and a 10-year labor warranty (Athena H₂, Vesta H₂, and Delphi H₂); the Melody II also includes lifetime parts coverage and a 5-year labor warranty.
Enagic Kangen Ionizers:
- Use large, straightforward electrode plates, but lack advanced cleaning systems and innovative power technologies.
- Many models feature simple filters and product engineering, requiring occasional maintenance or external filtration for added safety and peace of mind.
Bottom Line
- If filtration quality and independent validation are your top priorities, AlkaViva H₂ ionizers significantly outperform Enagic Kangen models. With AlkaViva, you can be reassured that you are getting the best in water ionization technology, robust hydrogen-rich water, long-lasting electrodes, and automated maintenance. For those interested in robust hydrogen-rich water, long-lasting electrodes, and automated maintenance, the H₂ series is also clearly superior.
- While Kangen devices are popular and well-marketed, their filtration capabilities are limited, and their performance is often surpassed by much more advanced H₂ series technology.
AlkaViva H2 Water Ionizer Filters & UltraWater Filtration
The AlkaViva company has developed proprietary, patented UltraWater filters for the AlkaViva H2 Series water ionizers. The reason UltraWater filters are superior to others is that they utilize a special method, borrowed from NASA’s space program filtration technology, which combines the very best filter media into a single block. When water flows through that block, it cannot escape the filter media. The result is 99.99% contaminant removal, compared to other filters that average about 50-85% contaminant removal.
The H2 Series water ionizers come with two UltraWater filters installed. The right-side filter is referred to as the prefilter, and the left-side filter is referred to as the secondary filter.
The Water Cells of the H2 Water Ionizers & Why They're More Advanced Than Any Others
The type of automatic cleaning for the plates in a water ionizer is crucial to its efficiency and the longevity of the water cells. The reason continuous-cleaning is essential lies in the technology of water ionization. Platinum is a catalyst for ionization (speeds it up), and if it is not able to touch the water passing through the water cell, that water will not get very well-ionized. This has nothing to do with the size of the water cell or the amount of electricity used. It is a fundamental law that to ionize platinum quickly, it must come into contact with the water during electrolysis. Very simple, but it gets complicated by the fact that platinum acts as a magnet for calcium. Within seconds, it can pull enough calcium onto itself to slow down the ionization process. When the polarity of the electrodes is reversed, then calcium is pushed away from them. All water ionizers reverse polarity to remove calcium from the water cells. However, most don’t reverse it often enough -- and so calcium sticks to the plates. Continuous cleaning is the only technology that keeps this from happening.
Continuous cleaning is a patented technology, and most other water ionizers (e.g., Tyent, Life, Enagic) do not have it. They use a far inferior system of cleaning the electrodes, where the electrodes are reversed after about 20 liters (which is not good enough). So, most water ionizers, regardless of what the companies claim about themselves, are not advanced or superior... period.
AlkaViva H2 water ionizers are superior, and one reason is that they use continuous cleaning. In fact, the system of constant cleaning used in H2 water ionizers is the latest and most advanced form of continuous cleaning available.
The water cell in an H2 water ionizer is also designed to be robust and resistant to breakage or leaks.
So, if you want a water ionizer that will last the longest, perform the best, and can be reliably hooked up to continuous water pressure (such as direct-plumbed or under-sink installation), I highly recommend getting an H2 water ionizer.
AlkaViva Passes the Test for the Most Important Features to Look at in a Water Ionizer
- I can't stress enough how important the strength of the water cell is. You don't want a leak, ever. AlkaViva H2 WATER IONIZERS ARE STRONG ON THE INSIDE: With H2 water ionizers you don't have to worry about being told you can't install it under your sink if you ever want to. These are very strong water ionizers and can hold up to the internal pressure of undersink installation, or any other kind of pressurized installation, very well. The water cell and all internal parts are warranted for life.
- The filtration is also a super important part of any water ionizer. Getting good filters is something I insist upon. AlkaViva UltraWater filtration is the best water filtration on the planet.
- Of course, the performance, how well the machine works to ionize the water, is super important. AlkaViva water ionizers rank best in performance too.

AlkaViva Water Ionizers are covered by AlkaViva warranties. AlkaViva water ionizers have the lowest return rate in the industry. Whenever there is a repair needed with your electric ionizer, you can be confident you'll be quickly taken care of. Both the AlkaViva Lifetime Warranty and our top-notch customer service are great protection for you well into the future.
AlkaViva Warranty Details are as Follows:
Note: Warranty does not apply if the ionizer has been used for selling or vending water commercially. If a commercial warranty is required, please contact us.
The warranty on AlkaViva electric ionizers begins on the original purchase date. Normally, if warranty details are not received by AlkaViva within 30 days, then the warranty is limited to 1 (one) year. But don't worry; if you purchase your AlkaViva water ionizer from us (AlkalineWaterPlus) we will register your warranty for you. The AlkaViva Lifetime Warranty covers all electric ionizer parts (not accessories) and 100% of labor costs in the first 5 years. After the first 5 years, the purchaser is responsible for any labor costs. In no event shall AlkaViva or its dealers be liable for any direct, indirect, incidental or special consequential damages to property whatsoever, arising from use of its products with improperly treated or untreated hard water.
With AlkaViva warranty fulfillment, the customer is responsible for all shipping. The support department will assign an RMA number, which must be on the shipping label or the package will not be accepted. Instructions for preparing the water ionizer to ship and then shipping the water ionizer safely will be emailed. These need to be fully followed or damage could occur in shipping.
The warranty expressly excludes environmental damage including (but not limited to) mineral build-up due to hard water or high levels of iron, poor source water quality, infestation, or electrical surges. Warranty is also excluded if non-genuine filters (sold by other than anyone other than an authorized AlkaViva Dealer) are used in an ionizer. Any authorized site will state clearly that they are an “Authorized AlkaViva Distributor.” Non-genuine filters have been shown to not only impair performance, but also to leak out media that has and can damage ionizers.
