Description add

The Alkaviva Delphi H2 is the eagerly awaited upgrade to the original Ultra Delphi undersink water Ionizer.  The new 2018 Delphi H2 is the undersink version of the world's best performing countertop water ionizer; the Alkaviva Vesta H2. Using the Alkaviva Vesta H2 as the workhorse under your sink the new Delphi H2 features a beautifully designed touchscreen faucet for your countertop. The Touchscreen faucet allows you to easily select Alkaline, Acidic and Purified water by simply touching the display.

The new Alkaviva Delphi H2 Water Ionizer is quite simply the best undersink water Ionizer for sale in world today. No other undersink water Ionizer we have ever tested comes close to the producing such high negative –ORP and H2 levels at drinking water levels (8pH – 9pH).

The Delphi H2 also has the most advanced water filtration we’ve tested in a water ionizer.  The dual ultra water filtration system removes 99.9% of contaminants including chlorine, chloramine, pharma, heavy metals and resilient contaminants like chromium VI and arsenic. The new 2018 models includes UltraWater Smart Chip filters so you know exactly when to change your filters. The result is you get the safest, cleanest, healthiest, best tasting water from any Ionizer on the market today.

The 9-Plate Alkaviva Delphi H2 is an upgrade of the award winning Ultra Delphi Ionizer and now offers you the finest on-demand Hydrogen generation technology you can buy. It is the zenith in our new H2 Series. Molecular Hydrogen (H2) has been scientifically shown to be the most powerful antioxidant known to man with its health benefits detailed in over 600 Medical and Scientific studies to date.

Most alkaline water drinkers naturally gravitate toward drinking water that is somewhere between pH 8 to pH 9 for the simple reason it tastes better than water with pH 10 or higher. It is safer too. This poses a problem. You end up drinking water at a low pH that tastes good but doesn’t have beneficial levels of H2. Or to get good H2, you have to drink water with pH 10 or higher, which isn’t palatable - or recommended by the KFDA or Japanese Ministry of Health. Something has to give; you can’t get both.

That is until now! The Delphi H2 with Hydrogen Infusion Technology is the world's leading Ionizer for H2 performance, and does so in the recommended - and great tasting – pH 8 to pH 9 range. We are achieving an ORP of -840 and H2 readings of 1.6ppm when we test the Delphi H2 at pH 9!

The Alkaviva Delphi H2 Water Ionizer is also backed by a full 5 year warranty from our own dedicated UK service centre. Buy with peace of mind, are an Official UK & European Master Retailer for Alkaviva Water Ionizers.

The new Alkaviva Delphi H2 is perfect for those who require a clutter free countertop and demand the very best in performance, design and aesthetic appeal. Like its countertop variant, the new Delphi H2 sets the standard by which all undersink water ionizers will be measured.  

10 Reasons why the all new 2018 Delphi H2 Water Ionizer is the Best Ionizer for sale in the World today

Stunning Faucet Design – The new Delphi H2 stainless steel faucet is perhaps the most elegant and well-designed touchscreen faucet available for a water ionizer. Easy to use with compact design and ‘One Touch Technology’ allowing you to easily and precisely control your ionizer's functions with one touch, the new Delphi H2 faucet radiates luxury without over complicating matters as some ionizers manufactures have done by adding large ipad style screens to their faucets.  

Exceptional Alkaline PH Range - The new Delphi H2 is able to produce Alkaline water with a pH of up to 12! Drinking water with an alkalinity of pH 12 is not recommended, however at the optimal drinking level range of 8 to 9 pH the Vesta H2 can produce a remarkable Trio combination of up to -840 ORP and 1.6ppm H2 making it the world’s best performing ionizer for drinking water, hands down, no other ionizer we’ve tested comes close on these metrics.

World leading ORP Performance – The Delphi H2 can produce an ORP of up to -920 at the highest pH setting and an ORP of -840 at drinking level pH ranges 

Highest H2 performance at lower, drinkable levels of pH which tastes great!Most other systems can create at least a low level of H2. However, any system that creates decent H2 has to run at a maximum setting and produce water above 10 pH to achieve that result. Not only is it questionable in health terms, but water that high in pH tastes bad! It also stresses the electrodes in the machine. The Delphi H2 is better than any other system at delivering H2 performance, especially at lower more drinkable - and safer - pH levels. We can’t stress this point enough. Cleaner, healthier and better tasting water.

13-stage Dual water filtration system featuring UltraWater technology – No other ionizers on the market today feature the advanced filtration provided by the Dual UltraWater filters included in the Delphi H2 Ionizer. The Delphi H2 UltraWater filters remove Chlorine, Lead, Arsenic, Copper, Manganese, VOC’s etc.… to virtually non detectable levels. Alkaviva ionizers do not use cheap Vitamin C or carbon filters. The 2018 model includes UltraWater Smart Chip Filters so you know exactly when to change your filters.

9 advanced SmartDesign Solid Plates / Electrodes - We do not believe in over-sized or over-powered electrodes, which are often a sign of inefficient design. These plates degrade much faster and have questionable performance especially after 18-24 months of use. Other ionizers with nine or more electrodes require A LOT of power to run them. Some even have to slow the flow rate. Our engineers found that you get the best performance when you have a highly engineered electrode design matched with proper power density. Our SmartDesign Solid Plates / Electrodes are manufactured in Japan and engineered to deliver maximum efficiency. The Delphi H2 offers you the perfect combination of electrode design and count and the optimal power to run them. The result is a great flow rate, top performance, absolute reliability and lasting durability.    

Fully automatic DARC Cleaning System -  Cleans the Ionizer with every use. Alkaviva pioneered DARC cleaning. This is simply the best way to help ensure that the most critical component of the ionizer – the electrodes – stays free of scale buildup. Scale is the enemy of performance. The Delphi H2 continues our tradition of offering the best cleaning system so you get great performance, especially over time. It also gives you the peace of mind of never having to think about cleaning or waiting for a cleaning cycle to complete. The Delphi H2 for the best performance and ultimate convenience!

Real-time Flow Control System - Optimal flow rate is also critical in achieving optimal pH,ORP and hydrogen performance. The Vesta H2’s Real-time Flow Control System provides an LCD display and a selectable valve that allows you to set easy and precise control of your flow rate.

AutoAdjust -  With AutoAdjust the power can be adjusted to the optimal level for your water ensuring you get peak PH, ORP and H2 performance each time you use your Delphi H2.

5 Year Full Warranty - We provide a full 5 year warranty and have our own dedicated UK service centre.

H2 Hydrogen Performance

Ionizer performance used to be entirely focused on pH/ORP and the number of plates/electrodes an ionizer had. While pH/ORP are exceptionally important in alkalizing and detoxing our bodies  water filtration and Ionizer science has moved on with a focus on H2 performance. H2 has been shown in over 600 studies to give a therapeutic benefit in 140 health conditions and disease models.

In the past Ionizers were not able to generate H2 at safe drinking PH levels. Other ionizers on the market can only generate beneficial H2 at pH levels in excess of pH 10. That is until now. The new Alkaviva H2 range outperforms other ionizers in H2, and does so in the recommended - and great tasting – pH 8 to pH 9 range.

How our water cells / plates create H2

The water cell - the engine of the ionizer - has two components: electrodes and (ion exchange) membranes. Ionizer performance used to be entirely focused on pH/ORP and the electrodes. H2 Infusion Technology is based on the fact that membranes are as critical as the electrodes. Other ionizer manufacturers buy their membranes from outside sources. In comparison, Alkaviva membranes are made in-house and are ultrasonically pressed, rather than bonded with chemicals. This provides you with a distinctly superior membrane that is designed to work specifically with our electrodes, giving unmatched performance.
When you marry our advanced SmartDesign electrodes to our infusion membranes, the result is H2Infusion Technology and better H2 performance. This is especially so at the better tasting lower levels of pH.

Benefits of H2 Hydrogen

Incredible Antioxidant Power - Exercise requires more oxygen than most activities. Increases in oxygen can produce free radicals, leading to chain reactions and cell damage. Oxidation is literally the aging process while antioxidants prevent or slow down the oxidative damage. Most antioxidants neutralize bad radicals, but they can also neutralize the good ones that your body needs. Molecular hydrogen selectively targets only the damaging oxygen radicals, leaving behind the good radicals. This makes it a superior antioxidant.

Improves your Hydration - When H2 molecules combine with and neutralize damaging oxygen radicals, they are transformed into water (H2O) - increasing your cellular hydration. The ionization also creates a light, silky-smooth tasting water that is easy to drink.

Increase in Energy - Adenosine Triphosphate (ATP) is the fuel that powers your cells during physical activity. Drinking H2 infused UltraWater helps maintain the high ATP production needed during exercise - providing optimal strength, endurance and recovery.

Reduced Muscle Fatigue - Lactic acid buildup leads to fatigue, muscle damage, decreased endurance, reduced performance, and poor training results. Peer-reviewed research on athletes shows that molecular hydrogen decreases lactic acid levels.

Fight Free Radicals - Drinking hydrogen-rich alkaline water is the perfect way to mount a defence against free radicals, which are responsible for oxidization – or decay – within our bodies.

Gum and dental health – A 2014 study showed that hydrogen water can improve gum health, and also help to neutralize acids in your mouth following a meal or snack. For more information see -

Hydrogen Water Effect On Diabetes - In 2008, a team of Japanese researchers carried out an experiment using 30 subjects with type 2 diabetes. Over an eight week period, the subjects who were given hydrogen-rich water to drink on a daily basis presented with greater levels of improvement in their diabetes-related symptoms. The implications of this research are pretty far-reaching and encouraging! For more information see -

Alkaline Hydrogen Water Might Help To Prevent The Loss Of Cognitive Ability - A recent study using mice as the test subjects, showed that mice which drank hydrogen water experienced less neuro-degeneration than the mice which drank regular water. J Clin Biochem Nutr 46:269-76 (2010). For more information see -
