AlkaViva Melody II Countertop Water Ionizer


The original Melody was our leading selling 5-Plate Water Ionizer over the last ten years. The new 2018 Melody II has been completely redesigned and is the top-performing 5 plate Water Ionizer on the market today. It has been redesigned with next generation SMPS power supply and DARC cleaning and features Hydrogen Infusion Technology that specifically optimizes performance, especially the production of molecular hydrogen or H2.

Like its big brothers the Athena H2 and Vesta H2 the Melody II produces exceptional  –ORP and H2 at lower drinkable levels of pH. You get the new performance standard along with the same solid reliability all beautifully packaged in an updated and more attractive design. Everything that made it so trusted and popular before is now vastly improved.

The new AlkaViva H2 series of Ionizers also have the best water filtration we’ve tested in any water ionizer.  The Melody H2 is also a dual water filtration system and removes 99.9% of contaminants including chlorine, chloramine, pharma, heavy metals and resilient contaminants like chromium VI and arsenic. The new 2018 model 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.

Most alkaline water drinkers consume water between pH 8 to pH 9 for the simple reason it tastes better than water with pH 10 or higher and it’s safer too. This meant a compromise in the past, most ionizers boast being able to produce very high pH levels but at the drinking water range they often produce poor H2 and -ORP readings, that is until now, the New Melody II produces excellent –ORP and H2 levels at drinking water levels, for example at a pH of 9 we were able to achieve a -ORP of 700 with the Melody II and a H2 reading of 1.1ppm – This is market leading performance, and betters the performance of many 9 plate ionizers from other leading brands.  No other 5-Plate Water Ionizer on the market today can produce such high quality purified and antioxidant water.

7 Reasons to choose the all new 2018 Melody II Water Ionizer

Excellent Alkaline PH Range - The new Melody II is able to produce Alkaline water with a pH of up to 10.8 making it one of the most powerful value-priced Ionizers on the market today! Drinking water with an alkalinity of pH 10.8 is not recommended, however at the optimal drinking level range of 8 to 9 pH the Melody II can produce a combination of up to -700 ORP and 1.1 PPM H2, making it one of the top performing ionizers for drinking water.

5 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 7 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 Melody II 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.   

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 Melody 2 Ionizer. The Melody 2 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.

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. The Melody II is better than other overpriced systems at delivering H2 performance, especially at lower more drinkable - and safer - pH levels.

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 Melody II 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.

Real-time Flow Control System - Optimal flow rate is also critical in achieving optimal pH, ORP and hydrogen performance. The Melody II 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.

Price - The Melody II delivers exceptional value for money from one of the worlds most established Ionizers brands when compared with more expensive overpriced Ionizers in pH, ORP and H2 metrics.

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 500 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 -
