The Delphi H2 Water Ionizer: A Testament to Strength & Reliability

The AlkaViva DELPHI H2 Under-Sink Water Ionizer is the only under-sink water ionizer I ever recommend. It is the strongest against leaks. No other under-sink water ionizer is as strong or worry-free as to make this statement.

The Delphi H2 is the most reliable water ionizer I have ever seen.

The Delphi H2: A True ‘State-of-the-Art’ Water Ionizer! With the most advanced features and technology, it guarantees years of the highest-quality performance. Don’t settle for second best when it comes to an under-sink water ionizer.

The AlkaViva Delphi H2 is The Definition of a State-of-the-Art Water Ionizer

After years in development, the Delphi H2 is genuinely the best under-sink water ionizer available.

The AlkaViva Delphi H2 water ionizer has been designed with phenomenal “Hydrogen Infusion Technology” to give you the most available molecular hydrogen of any under-sink water ionizer.

Get the highest quality of water ionizer construction, filtration, and performance. The H2 water ionizer is the best and will continue to be the best, with very little maintenance, well into the future.

The Water Cell - Built to Withstand Pressure

The Delphi H2 Water Ionizer: A Testament to Strength & Durability. The water cell was designed to withstand far more pressure than any other water ionizer, ensuring high leak-resistance. 

Under-sink water ionizers are out of sight and operate against gravity with high and constant pressure; therefore, they require the most substantial resistance to leaks. 

9 of the Highest Quality Plates

The Delphi H2 has 9 of the highest-efficiency solid platinum titanium electrodes on the planet. These efficient, super-high-performing plates deliver antioxidant power. 

The following section explains why you can trust that the Delphi H2 will continue to perform exceptionally well, providing high levels of antioxidants and requiring minimal maintenance throughout its lifespan.

AutoClean™ - Advanced Plate-Cleaning Technology (Advanced Continuous-Cleaning)

All water ionizers have cleaning systems, which are crucial to their performance and durability, but not all cleaning systems are created equal. The Delphi H2 features AutoClean, an advanced form of continuous cleaning. Without constant cleaning, calcium and other minerals attach themselves to the electrodes. However, with AutoClean, the electrodes switch on and off so quickly and pulse with differing widths that minerals don’t have the time or stability to form a bond with the electrode surface. Other, less sophisticated water ionizer brands cause you to periodically wait for your alkaline water. The AutoClean reversal mechanism operates in the background of the Delphi H2, always cleaning and never interrupting the flow of alkaline drinking water. You never have to wait or worry. 

One of the most essential features that separates BEST water ionizers from all the rest is their method of cleaning the electrodes. With continuous cleaning, you can be secure in knowing your water ionizer will maintain like-new performance for years and even decades into the future. Even the slightest film of calcium on the electrode plates can reduce a water ionizer’s capability of getting great ORP and H2 levels, so continuous-cleaning (never letting calcium stick to the plates) is a big deal.

Hydrogen Infusion Technology 

The Delphi H2 water ionizer is equipped with Hydrogen Infusion Technology, a unique feature that ensures it delivers the most available molecular hydrogen of any other under-sink water ionizer. This technology enhances the antioxidant power of the water, providing you with health-boosting benefits.

Volume Control

See the back of the machine (lower-left) for volume control.

AutoAdjust

The Delphi H2 water ionizer features AutoAdjust, a unique feature that automatically adjusts the ionizing power to deliver optimal ionization every time. This means you don’t have to worry about manually adjusting settings, ensuring you always get the best in strength and performance when you install a water ionizer under the sink.

Power

The Delphi H2 Water Ionizer is powered by the industry’s best technology, ensuring you the highest level of performance and reliability.AutoClean (continuous-cleaning of the electrodes) with advanced cleaning capability

• AutoAdjust™ optimizer automatically adjusts the ionizing power to deliver optimal performance and ionization for your specific water source.
• The Smart Switch™ next-generation SMPS power supply provides the most stable and efficient power platform.
• 9 high-efficiency solid platinum titanium electrodes deliver more antioxidant power than any other water ionizer.
• Hydrogen Infusion Technology
• Advanced self-diagnostic MICOM (mini-computer) circuitry system
• UltraWater Filtration

Smart Switch: Advanced SMPS Technology

The Delphi H2 water ionizer utilizes the most advanced Switch Mode Power Supply technology to operate its unique AutoAdjust™ feature. Current generations of SMPS offered by other ionizer companies cannot automatically adjust voltage on demand to match varying water conditions. The advanced SMPS used in the Delphi H2 is capable of doing that. SMPS is known as a power-saving option as it only uses the amount of power necessary.

Advanced Self-Diagnostic

The MICOM circuitry system, part of our advanced self-diagnostic technology, allows for the advanced features to function and protects your investment. Smart Sensors signal excessive temperatures, whether from a power surge or high water temperatures, and shut down your ionizer to defend it, ensuring its longevity.

Advanced Electrode Technology

The Delphi H2 water ionizer features 9-Ultra Efficient Electrodes made of the highest grade Titanium / Platinum for durability and efficient ionization. This advanced electrode technology ensures that you get the most out of your ionizer, providing high-quality ionized water every time. 

Advanced Protection Against Hard Water

Hard water can be very destructive of a water ionizer, and often your warranty isn’t protected against it. However, the Advanced design of the H2-Series water ionizers protects against hard water more effectively than any other water ionizer. For hard water protection, the Delphi H2 stands alone.

Delphi H2 Sleek Design & Faucet Features

The Delphi H2 faucet is fully functional and beautiful. 

The Delphi H2 faucet features a modern, mirror-faced, sleek design that adds a touch of elegance to your kitchen. Its small footprint ensures it complements any contemporary kitchen décor, making it a perfect blend of style and functionality.

Custom Colors

If you would like a different color for your faucet than the ones pictured above, please contact us at support@alkalinewaterplus.com or include your request in the comment box of your order. Delivery of a custom color order may take a few weeks, and an additional $200 charge applies for customization.

H2 WATER IONIZERS ARE STRONG ON THE INSIDE

With H2 water ionizers, you can install them under your sink without any worries. These are robust water ionizers, equipped with built-in features to protect against scale, water line breaks, or other compromises to the machine’s integrity, ensuring the safety of your investment.

Advanced UltraWater Filtration

All H2 Water Ionizers utilize the highest-quality filtration. 

Patented dual filters, consisting of 0.1-micron filters, combine with space-fiber technology to efficiently filter almost any tap water. The filter life change indicator lets you know when it’s time to replace your filters. Two filters are provided to ensure your water is filtered properly. These advanced filters also feature built-in anti-scale filtration.

UltraWater filtration is another outstanding feature of the Delphi H2 under-sink water ionizer. You can get no better filtration for your water than UltraWater filtration - anywhere or at any price! 

UltraWater filtration ensures you peace of mind, knowing your water is not only alkaline and ionized, but cleaned better than any other filtration system.

• “Absolutely love our AlkaViva Delphi H2 water machine. The water tastes incredible.” David G.
• “I did a lot of research before buying my next ionizer, and once I found your website, it made things so much easier to compare. I bought the under-the-counter Delphi H2, and I’m very happy with my decision. This water machine can enhance your body and keep it clean if you drink the proper amount of daily water. The detailed and honest research that was done is right there for you to see for yourself. Thank you again, ALKALINE WATER PLUS, for everything.” Perry L.
• “I’m happy and contented with drinking, cooking, and cleaning water now, with my new Delphi H2. It’s already changed my appetite for drinking more (and better) water!” David H.
• “Love the Delphi H2 ionizer: Recently I bought a this beautiful water ionizer for under the kitchen sink. The water tastes wonderful. The ability to easily adjust alkalinity from the faucet is super convenient. It is fairly small compared to the reverse osmosis filter that used to be there. There are 5 levels of alkalinity, which are easily selectable from the faucet itself. For me, it was worth it, and I would happily make the same choice again. I love the faucet and the water that comes out of it.” Lin W.
• “The Delphi H2 is a great machine. The install was simple. The water’s taste is amazing, and even my children are drinking more of it. This ionizer is more than I expected. LOVE IT!!” Fernando R.
• “I used to feel so bloated when I drank water, but I actually feel hydrated by ionized water. I was thrilled to discover this company. They answered all of my questions, were super knowledgeable, and answered the phone right away! This seems so rare now, and I so appreciate their service and all of the information on their website.” Kara B.
• “This Delphi H2 was pretty easy to install. The installation video guides you step-by-step through the process. We started drinking at the alkaline level 1 setting as recommended by Sean. I tested the water using the included reagent, and it seemed high, coming in around a pH of 9-10. A week later, I retested it using level 1 and obtained a more realistic reading for that level, which was 7-8. I was told that the new filters push the alkaline levels up until they are run for about a week. The first day or so after drinking the water, I felt achy all over. So I guess I was releasing toxins from my body. After a few weeks, we are now running at level 3, and our bodies have acclimated to it just fine. We are delighted with the system so far and hope to feel the benefits from drinking this water soon.” RICHARD R.
• “The Delphi H2 Undersink Water Ionizer is excellent. Love it. Drinking ionized water to solve my dehydrated problem.” Kim L.

• “Ionized water is great! My husband thought he had gout in his feet, and the pain went away the first day drinking this alkaline ionized water!! I have Lyme disease and suffered from fatigue, and now it’s gone! I also breathe so much better at night! My kids, in the first week of school, went to their grandparents’ house over the weekend and caught a cold, and I believe it’s because they weren’t drinking the water. After all, they came home and were better in a day! I use the acidic water that comes out as a byproduct of the alkaline water to clean everything!!! I also use it on my kids’ eczema on their arms, and it’s been miraculous how it’s improved overnight. I have a Waterpik glosser, and I put acidic water in it. My teeth and mouth feel so clean, and I know they are! I add a few drops of essential oils to the water, and it’s the best-smelling and most effective cleaner I’ve ever had. Take my advice and buy this!!” Christy

Filter-Changing Instructions

Replacing filters is a simple process. By following these steps, you can ensure an easier time with filter replacement in the future.

1. Shut off the water flow.
2. Turn on the alkaline flow (as if water were coming out). This releases pressure or suction in the line.
3. Replace the filters only now that the pressure has been released.
4. Another thing to note is that the small 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 applying food-grade lubricants, such as olive oil or coconut oil, to the O-rings on the unit where the filters are located.
6. If you still have any difficulty, use a slight tilt back and forth while pulling up on the filter.

Also, be sure to order your filters from us to ensure you receive the correct ones. I want to emphasize the importance of selecting the proper replacement filters.

If you encounter any issues, rest assured that we are here to help. Contact us immediately by phone or email, and we will ensure that you receive the support you need quickly and efficiently.

IMPORTANT NOTES

• With all water ionizers, a small amount of residual water is typically left over from quality-check testing, so plugs are placed on all water ionizer ports. Please follow these guidelines for removing the quick-connect plugs. Also, save these plugs in case you ever have to ship your Delphi water ionizer.
• Note: All pH and ORP levels are approximate, depending on local water supply, because water ionizers don’t always work the same in every location.
• Flow Control (If you ever get an AOF error code) The newest models of the Delphi H2 come with a flow restrictor valve. It is an optional part used for a Delphi H2 when it displays the A0F error code, indicating that the water pressure to the Delphi H2 is too high. This flow restrictor valve limits the flow to something the unit can handle.

  

  The other option to clear that error code is to adjust the flow at the angle stop adapter until the A0F error code disappears.
