Strength & Reliability of the Delphi H2 Water Ionizer

The AlkaViva DELPHI H2 Under Sink Water Ionizer is the only under sink water ionizer I ever recommend. It will never leak. No other under-sink water ionizer is strong enough or worry-free enough to make this statement.

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

The Delphi H2 is the definition of a "state-of-the-art" water ionizer! With the most advanced features and technology. It will provide you with 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 a number of years in the making, the Delphi H2 is really the absolute best under-sink water ionizer available.

The AlkaViva Delphi H2 water ionizer has 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 Will Never Leak

The Delphi H2 Water Ionizer is strong. The water cell was built to withstand far more pressure than any other water ionizer and therefore never leak. Because of this the Delphi is the only under-sink water ionizer I recommend.

When you install a water ionizer under the sink, you need to know it won't develop a leak over time. Because under-sink water ionizers are out of sight and operate up against gravity with high and constant pressure, they need to have the strongest resistance to leaks. I don't recommend any other under-sink water ionizer than the Delphi H2. 

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 will deliver more antioxidant power than any other under-sink water ionizer. 

You can trust that the Delphi H2 will continue to perform outstandingly-well, giving high levels of antioxidants, and with very little maintenance, for the life of the water ionizer.

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

All water ionizers have cleaning systems which are crucial to performance and durability, but all cleaning systems are not created equal. The Delphi H2 uses AutoClean™, an advanced form of continuous-cleaning. Without continuous-cleaning calcium and other minerals attach themselves to the electrodes. But, with AutoClean, the electrodes switch on and off so quickly and pulse differing widths, so minerals don't have the time or stability to form a bond with the surface of the electrode. 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 important features that separates out 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 stay capable of like-new performance 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 fact that the Delphi H2 water ionizer has Hydrogen Infusion Technology means it will give you the most available molecular hydrogen of any other under-sink water ionizer.


The Delphi H2 water ionizer has AutoAdjust™, which automatically adjusts the ionizing power to give you the best ionization always. When you install a water ionizer under the sink, you really need the best in strength and performance.

Industry's best technology is used in the Delphi H2 Water Ionizer

  • AutoClean (continuous-cleaning of the electrodes) with advanced cleaning capability
  • AutoAdjust™ optimizer automatically adjusts the ionizing power giving the best performance and ionization for your particular water source.
  • 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
  • Lifetime Warranty

Smart Switch: Advanced SMPS Technology

The Delphi H2 water ionizer uses the most-advanced Switch Mode Power Supply technology in order to operate it’s 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 able to do that. SMPS is known as a power-saving option as it only uses the amount of power necessary.

Advanced Self-Diagnostic

MICOM circuitry system allows for the advanced technology to function and protects your investment. Smart Sensors signal excessive temperatures either from power surge or water temperatures and shut your ionizer down to protect it.

Advanced Electrode Technology

9-Ultra Efficient Electrodes Made of the highest grade Titanium / Platinum for durability and efficient ionization.  

Advanced Protection Against Hard Water

Hard water can be very destructive of a water ionizer, and often your warranty isn't protected against 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 Delphi H2 is in a class of its own.

Delphi H2 Sleek Design & Faucet Features

The Delphi H2 faucet is fully functional and beautiful.

Delivery of a custom color order may take a little longer, i.e., a week or two. It depends on available stocks. 

Advanced UltraWater Filtration

All H2 Water Ionizers use the absolute best 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. You have the ability with two filters to really make sure your water is filtered properly. These advanced filters also have anti-scale filtration built in.

UltraWater filtration is another of the outstanding features 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.

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.
