Extra levels of pH means greater choice for you and other users. It also allows you to take advantage of higher alkaline pH levels when cooking, to make greens greener, rice fluffier and coffee and tea more flavorful.

Varying levels of acid water output means you can avail yourself of all of many ways you use acid water; for your skin, for your plants, for your home hygiene and more.

Pure water selection can be important if you or visitors are on an acid-based drug regimen. Although alkaline micro clustered water helps the absorption of many supplements and reduces the dosage requirement, it may affect drugs that are designed to be taken with acid or neutral water.

0.1 micron 3-stage filtration plus BioStone Infrared means that not only is your water filtered of impurities to the very finest degree, but it is also preconditioned by reduction of surface tension for maximum negative ion production during ionization. The 3-stage filter also adds coral calcium to the water automatically. There is no substitute for a quality, replaceable filter. Imagine what your sink would be like, after a year, if you only used hot water to clean it!

Large 5-plate polymer ion plated platinum coated titanium ionizing plates. Some older design water ionizers still use stainless steel plates, which were found to emit nickel. Jupiter Science and Toyo Water of Japan collaborated to produce the finest system of polymer bonded platinum coated Titanium plates. These totally overcome this leaching problem and radically enhance the lifespan of the plates, which are the heart of your Melody system.

A stainless steel top spout may seem a small thing until you actually use an Ionizer without one.

Integrated computer circuitry means CHOICE. Some units on the market try to make out that they are ionizers but do not use computer controllers. This means that you are restricted by the pH of your incoming water and not able to adjust to the optimal pH for your own needs.

Post-operation Auto Cleanse System means that every time you use your 'Melody', it will undertake a silent, automatic cleanse of the Titanium ionizing plates in the heart of its system. This auto clean ensures continued maximum performance by removing any particles that may have gotten through the filter into the ionizing chamber.

Voice confirmation means you are alerted to any change of pH. This safety feature can also be reduced in volume or turned off once you have learned how to use the Ionizer properly. it's like a 'learner-driver instructor' on board.

Filter usage Liquid Crystal display means you can see at a glance how much filter life you have left. Although not an actual measure of filter life, it's a handy indicator off longevity that you can use to assess when to order a new filter.

Optional ability to connect direct to mains means you really don't even need your Melody attached to your tap. With a 1/4" hole in your bench, it can attach direct to your mains. All you need do to have a glass of water is to turn it on at the convenient front flow valve.

1/4 inlet tube; better visually in your kitchen that the 3/8" tube on other models. Why? Smaller is less obvious, and even though you may not want to connect your 'Melody' to the mains, and hiding the inlet hose completely, the 1/4" tube looks far better than the bulky 3/8" hose on other models.
