AlkaViva 9-Plate Vesta H2 Water Ionizer



Vesta H2 Water Ionizer

The Vesta H2 water ionizer is the most effective water ionizer for producing ionized water with the maximum amount of H2 (hydrogen antioxidants, or molecular hydrogen). Some of the features of the Vesta H2 water ionizer are the AutoAdjust Optimizer and SmartSwitch. Because of these and other unique features, the H2 water ionizers are the most functional water ionizers there are. H2 water ionizers use a proprietary method of converting AC power to DC, which is part of what excites the water into producing the machine becomes a powerhouse for production of H2-antioxidants. The Vesta H2 water ionizer has 9 plates, which are especially designed to give maximum performance. If you want the best water ionizer, the Vesta H2 is it.

Industry-first technology!

  • 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.
  • Advanced self-diagnostic MICOM (mini-computer) circuitry system

Advanced SMPS Technology

The Vesta 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 water ionizer companies cannot automatically adjust voltage on demand to match varying water conditions. The advanced SMPS used in the Vesta H2 water ionizer is able to do that. SMPS is known as a power-saving option as it only uses the amount of power necessary.

Advanced Plate-Cleaning Technology

All water ionizers have cleaning systems which are crucial to performance and durability, but all cleaning systems are not created equal. One more important advantage of AutoAdjust™, is that calcium and other minerals cannot attach themselves to the electrodes. With the electrodes switching on and off so quickly and pulsing differing widths, minerals don't have the time or stability to form a bond with the surface of the electrode. Other less sophisticated ionizer brands cause you to periodically wait for your alkaline water. The AutoClean reversal mechanism operates in the background of the Vesta H2, always cleaning and never interrupting the flow of alkaline drinking water. You never have to wait or worry.

Advanced UltraWater 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.

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 Vesta H2 is in a class of its own.

Sleek Design

Modern, Sleek Design Small footprint and elegant black and stainless-look design complement any modern kitchen décor. Experience the elegance and efficiency this ionizer!

  • The parts within the Vesta H2 water ionizer and all AlkaViva water ionizers are of fantastic quality. They should 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. The repair/servicing depot is located in Reno, Nevada.
  • With all water ionizers, there is usually a small amount of residual water, 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 Vesta water ionizer.
