Unmatched UltraWater™ Filtration

Smart Electrodes (5-Plates)

Improved DARC II Cleaning

Great performance at an entry level price

The Safety of UltraWater Filtration

UltraWater is the only alkaline water ionizer filter that is tested in an independent EPA-certified lab against 249 contaminants, reducing virtually all of them to 99.9%even the toughest.


Smart Electrodes: super-efficient & powerful

Smart Electrodes marry the purest Japanese titanium and platinum along with precise Korean engineering. The result? More efficiency and more performance that lasts over time. Now that’s smart.


New and Improved DARC II Cleaning

Since we introduced DARC in 2006, it’s been the best way to clean water ionizer electrodes and ensure lasting performance. DARC II is even more effective and more reliable, giving you more peace of mind.

H2 Infusion Technology

Top alkaline water system performance requires more than just electrodes. Our proprietary membranes combined with Smart Electrodes create H2 Infusion Technology…and unmatched H2 performance.


AutoAdjust Advanced Power Supply

High wattage is a sign of old, inefficient technology. It damages electrodes. AutoAdjust pulses the SMPS power to the electrodes ensuring you get maximum efficiency plus optimal – and lasting – performance.


Protective RISC Circuitry

RISC processors consume less power and offer the highest performance. RISC’s advanced technology performs diagnosis on the ionizer with each use. LCD notification alerts you of a fault protecting your investment.



  • 1. Choose from 8 pH Levels – Choose the level of pH that suits your needs.
  • 2. One Touch Convenience – One Touch Technology allows you to easily and precisely control your ionizer's functions … with one touch.
  • 3. Filter Replacement Alert – An LCD Filter Counter displays the filter life as you use it. Voice and icon reminders alert you when it is time to change your filters.
  • 4. Dual Filtration – On-board including our unrivaled UltraWater. No need for extra external cartridge like some other companies offer as “custom” filters. This means the cleanest water for less cost and less hassle.
  • 5. Precise Flow Control System – Provides better performance. You can monitor the flow rate on the LCD display and use the flow control knob to easily choose or set the flow rate you like.
  • 6. Twin Hot Water Protection – Twin sensors – one before each filter – protect your ionizer against the damage that can be caused by inadvertent hot water.
  • 7. Cell Safe Technology – The BPA-free water cell is made using NSF certified material and pressure rated to 90 psi.
  • 8. Installation Options – At your sink (attached with a diverter), at your sink (plumbed directly to the cold-water line), or under your sink with an Undersink Kit.
  • 9. Quality Finish – Compact size and superior look from leading manufacturer. Enlarged image here.

Consider 3 Important Things

Filter Performance

Hydrogen Production

pH and -ORP Production


Filter Performance

AlkaViva Filter Testing Is

  • Certified & credible: All tests performed in Independent, EPA / NELAP Certified Labs.
  • Thorough: We omit nothing and we show results for everything tested.
  • Real world: We tested contaminant levels in parts per million and that were as close to the EPA Maximum Contaminant Level as we could get.
  • Nothing hidden or left out: We reported everything – even the toughest to remove contaminants such as arsenic, chromium VI etc.
  • Comprehensive: We tested 21 heavy metals, 65 pharmaceuticals, 3 OTC drugs, 7 Hormones, 15 pesticides and herbicides, preservatives and wastewater indicators, 45 VOCs, and 5 other anions & disinfectants - a total of 172 contaminants!


Hydrogen Production

Most other systems can create at least a low level of H2. Anything that creates decent H2 also creates it in water that is dangerously high in pH – always well above 10 pH. Not only is it questionable in health terms, but water that high in pH tastes bad! The Melody II is better than other systems in its mid-range price category at delivering H2 performance, especially at lower more drinkable - and safer - pH levels.


-ORP and pH Production

The Melody II will (depending on source water) create up to an 10.0+ pH and -700 ORP. What is misleading and false marketing is to say an ionizer will get a particular result since the result will vary depending on the mineral concentration in your water and the flow rate. What we will guarantee is that if any customer can show, in the first 90 days after purchase, that our ionizer does not outperform any other brand ionizer using the same number of plates, the same flow rate and the same input water, then we will give a full refund.

Alkaline Water Benefits

Benefits backed by research.

Over 1,000 peer-reviewed studies show that molecular hydrogen - or H2 - has a therapeutic benefit in every organ of the human body and positively affects over 170 disease models and health conditions.

Ease your aches and pains.

Oxidative stress damages your cells, causing pain and inflammation. As we age, inflammation increases. Studies show that H2 neutralizes the damaging radicals. Drinking UltraWater can ease chronic and acute aches and pain.

Get your antioxidants - in your water!

Free radical damage causes oxidative stress and is one of the primary causes of aging. Oxidation causes iron or apples to “rust”. Antioxidants prevent or slow that damage. Unfortunately, anti-oxidants neutralize both beneficial and harmful radicals. Research shows the H2 in UltraWater specifically targets only the damaging radicals - making it the “ultimate” antioxidant.

Go longer. Go stronger.

ATP powers your cells. It is the source of your energy. Research shows H2 helps increase ATP production giving you more energy while decreasing lactic acid levels. Athlete? Exerciser? Just want more pep? UltraWater helps improve performance and recovery.

Drink more. Improve your health.

When H2 neutralizes damaging oxygen radicals, it creates water (H2O) - increasing your cellular hydration. Great tasting, silky-smooth, alkaline UltraWater is also easier to drink. When you drink more, you enjoy optimal hydration and better health.

Help balance your pH.

UltraWater is alkaline and ionized making it rich in naturally occurring beneficial minerals like calcium and magnesium that help you alkalize and maintain a healthy pH balance.
