It's an upgrade of the legendary JP104 water ionizer and now has advanced SmartDesign electrodes, which means the onboard continuous-cleaning is even more efficient than ever before and the strength of the water cell is also improved. The Melody II water ionizer also uses "Next Generation SMPS" power supply with AutoAdjust, the ability to automatically fine-tune it to your water supply!

Explanations of the New AlkaViva Melody II Water Ionizer Features

Continuous Cleaning: The Melody II water ionizer has one of the most advanced self-cleaning systems inside the water cell in the world! It's called continuous-cleaning. What this means is the Melody ionizer cleans itself all the time - while it's pouring. The Melody water ionizer delivers to you your alkaline water from the alkaline sprout without interruption. No more waiting even when your water ionizer is cleaning itself! Every water ionizer in the world, worth investing in, has an inbuilt cleansing routine. This ensures that any particles that may find their way past the filter are not 'caught' in the ionizing cells. The method is simple - the magnetic [electrical] field in the chamber is reversed so that any mineral that has energetically adhered to the Platinum on the electrode plate is repelled and flushed away. With the Melody water ionizer each time you use it, the poles are reversed automatically and continuously while pouring.

One reason that the Jupiter Melody was always one of the best water ionizers is because it used a basic form of continuous-cleaning. Now, with the upgrade to advanced continuous-cleaning the Melody II reverses polarity within the water cell even more frequently during use. Continuous-cleaning keeps a water ionizer free of calcium within the water cell. The results of this level of internal cleaning is that the Melody water ionizer will still be able to produce the same pH and ORP readings as brand new when it's 10 or more years old!

Mini-Computer - Integrated Computer Circuitry means that your water ionizer will perform at its peak without any attention from you. Computer circuitry ensures the best pH and ORP, always, but also allows other features to be fully automatic, such as hot water and low pressure protection.

SmartDesign Electrodes The electrode design of the H2-Series water ionizers is so proprietary that all I can tell you is they are designed to perform! In other words, they are expertly engineered to get the maximum molecular Hydrogen (H2-) or ORP per unit of pH of any other electrode design anywhere. The exact way that is done is a proprietary secret, but I can say it works. The performance is outstanding! These are pure, solid, medical grade platinum-coated titanium electrodes which are configured in such a way and combined with advanced electronics, to produce the best results.

The Melody II gives you an ideal balance between of five highly engineered SmartDesign Electrodes, the right amount and kind of power to run them, a great flow rate and solid performance.

Voice Confirmation means you are alerted to any change of pH. 

Filter Usage Display means you can see at a glance an estimate of how much filter life you have left. It's a handy indicator that you can use to assess when to order a new filter.

Direct Connect: Optional ability to connect direct to main cold water line means you really don't even need your Melody II attached to your tap. With a 1/4" hole in your counter, or a G2 faucet, it can attach directly to your cold water feed line. All you need do to have a glass of water is to turn it on at the convenient front flow valve.

Dimensions: L 10.5 x W 5.5 x H 13 in. [without packaging the Melody ionizer weighs 12.75 pounds]

Filtration: Be assured that with an H2-Series water ionizer you have awesome filtration. All new H2-Series water ionizers are shipped with patented UltraWater filters installed. This ensures you have the newest & best technology in water filtration with any of the new H2-Series water ionizers. 

Real-time Flow Control System: The Melody II’s Real-time Flow Control System gives you complete control of your flow rate. You can see and adjust the flow-rate with every use.

AutoAdjust: With AutoAdjust you can be sure the power is always adjusted to give you the best levels of ORP for your ionized water. This ensures you get the best H2 (antioxidants) at every level of pH. This AutoAdjust feature is an amazing upgrade and great feature of the Melody II water ionizer.

Top Certifications: Including ISO 9001 and 14001, UL standard for Low voltage electrical, NRTL, CE and KFDA

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 Melody-II is in a class of its own.

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.


Programming the H2 Water Ionizers

H2 water ionizers (including the Melody II) come already set for the average water. For those who want to, though, each level of acidic and alkaline water can be programmed to suit you. Or, for simplicity sake, if you have a general level you like, you can program only that level to suit you if you want. The way you do that is more simple than ever. 

  1. Get the water flowing at the level you want to program.
  2. Then push/hold the button for the level you are pouring.
  3. Next, push the button again (a short push) to toggle up (increasing the power up on a scale of 1-4 for that level).
  4. Giving another quick push will toggle it up again and when it gets to 4 it will go back to 1 with the next push. Once you are on the level you want then push the purify button to save it.
