compare AlkaViva H2 water ionizers & purifiers(2 filters)
We compared the new AlkaViva water purifiers (2 filters) – ionizers with Hydrogen Infusion Technology H2. the water purifiers-ionizers(Melody II H2, Athena H2, Vesta H2) , water purifiers -ionizers with Double Reverse AutoCleanse System for electrode / water ionization plates DARC, water purifiers – ionizers with SMPS power source and AutoAdjust technology (that dynamically & real time varies the power applied to the electrodes according to the varying mineral content of the filtered water that enters the water ionization cell), water purifiers-ionisers with SmartDesign electrodes (low power, small in size but energy effective),water purifiers – ionizers with 2 water filters (a water prefilter and water filter) , and water purifiers – ionizers with the most recent AlkaViva technology: infusion of hydrogen H2 
The ability to produce high concentrations of molecular hydrogen at a pH of around 9.5 is probably the most important thing to consider when choosing a water ionizer.
H2 hydrogen is the Master Antioxidant
It is the smallest element and lightest molecule so it easily diffuses into subcellular compartments scavenging dangerous oxygen radicals and so protects DNA and RNA from oxidative stress.
H2 hydrogen Activates your Body’s own Powerful Enzymes
H2 triggers the activation of additional antioxidant enzymes such as glutathione and other cell-protective proteins.
Research Suggests Therapeutic Benefit in Over 130 Disease Models
Over 350 peer-reviewed scientific articles indicate this fact. Drinking H2-saturated water produced the vast majority of the benefits observed.
H2 hydrogen Can Favorably Alter Cell Metabolism, Signaling and Gene Expression
Research suggests that H2 could improve cell signaling functions and provide anti-inflammatory, anti-allergic and anti-apoptotic (anti-cell death) effects.
H2Viva – the most powerful and proven molecular hydrogen.
