Delphi H2 Undersink Alkaline Water Ionizer


The 9-plate Delphi H2 Under sink Alkaline Water Ionizer

The Delphi H2 is your absolute first choice for the cleanest, healthiest, best-tasting, hydrogen rich, alkaline water!



The Delphi H2: pure perfection.

The New Delphi H2 Water Ionizer offers you these cutting-edge features: 



The Safety of UltraWater Filtration

The Delphi H2 offers you our UltraWater Technology plus 13 stages of cutting edge filtration to give you the healthiest water that is pristine and ultra-clean! The only water ionizer filter that is USA-made and has certified independent test results for 172 contaminants, reducing virtually all of them up to 99.9%. The healthiest water starts with clean water, don’t buy an expensive single filter alkaline system or one with cheap Vitamin C or carbon filters.


AutoAdjust Advanced Power Supply

The last piece of the performance puzzle is power. The answer is not high wattage and power consumption, that eventually burns out electrodes. AutoAdjust automatically modulates the SMPS power as it pulses to the electrodes ensuring you get maximum efficiency plus optimal – and lasting – performance. Automatically.


H2 Infusion Technology

Top ionizer performance requires more than just electrodes. Our proprietary membrane manufacturing combined with Smart Electrodes create H2 Infusion Technology…and unmatched H2 performance.


New and Improved DARC II Cleaning

We introduced fully automatic DARC in 2006 and it’s still the best way to automatically clean your electrodes and ensure lasting performance and without any annual servicing requirements. The new DARC II has been improved to be more effective and more reliable. This is simply the best way to help ensure that the most critical component of the ionizer – the electrodes – stays free of scale buildup. More peace of mind.


9 Smart Electrodes

The highest quality, Japanese titanium and platinum, along with precise Korean engineering, are what create the smart water ionizer electrodes. The most efficient, longest lasting and highest performing electrodes. That’s smart! Our SmartDesign Electrodes are 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.


Protective RISC Circuitry

RISC processors consume less power and offer the highest performance. RISC’s advanced technology performs self-diagnosis on the ionizer each time you use it. It protects your ionizer if there is any type of fault and notifies you on the LCD display.


8 pH Selectable Levels –  Choose the level of pH that suits your needs. Top H2 performance at lower, drinkable levels of alkaline pH that taste 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 Delphi H2 is better than other systems at delivering H2 performance, especially at lower more drinkable – and safer – alkaline pH levels. We can’t stress this point enough. Cleaner, healthier and better tasting alkaline water. Step up!

One Touch Convenience – One Touch Technology allows you to easily and precisely control your ionizer’s functions … with one touch.

Auto Adjust – with AutoAdjust the power can be adjusted to the optimal level for your water ensuring you get peak H2 performance each time you use your Delphi H2.

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.

Top Certifications –  Our 13 years in business means you can trust the Delphi H2, AlkaViva and our manufacturing.

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.

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 select or set the flow rate you like. The result is a great flow rate, top performance, absolute reliability and lasting durability.

Twin Hot Water Protection – twin sensors – one before each filter – protect your ionizer against the damage that can be caused by inadvertent hot water.

Cell Safe Technology – the BPA-free water cell is made using NSF certified material and pressure rated to 90 psi.

Installation Options – at your sink (attached with a diverter), at your sink (plumbed directly to the cold-water line), or under your sink.
The Delphi H2 water ionizer outperforms other ionizers in H2, and does so in the recommended – and great tasting – pH 8 to pH 9 range. That gives you the best of both worlds. The Delphi H2 offers you an industry-best water filtration system, the latest features and finest on-demand Hydrogen generation technology you can buy. It is the zenith in our new H2 Series. The result is you get the safest, cleanest, healthiest – and very importantly – best tasting alkaline water.
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.

How long will the filter last?

Filter life always depends on input water quality. The more unwanted stuff in the water, the harder the filters has to work. Generally the AlkaViva Delphi H2 filters will last a year – depending, as always, on the source water circumstances i.e. too alkaline too acidic or hard water/calcium. Our one year recommendation is based upon a family of 4, who use about 2 litres each a day (8 glasses) for drinking. If you use less, your filter may last longer or contact us for some suggested pre-filter options. In any case your AlkaViva Delphi H2 is ‘so intelligent’ that it will indicate to you when the filters need changing. So no need to worry!

Do you have a video on the Delphi H2 ioniser?

Yes! Please meet the Delphi H2 ioniser in person, see our video here There are many more video’s on the AlkaViva Delphi H2 and other AlkaViva products available on YouTube.

The AlkaViva Delphi H2 looks amazing but does it perform?

Just imagine if you could instantly get healthy alkaline water for you and your family from a water ionizer manufactured by a leading manufacturer. Imagine a faucet that has been engineered for good looks and performance – not an ugly add-on to an existing countertop unit. Now imagine that all you see is a discrete and elegant chrome plated faucet that is activated by an easy-to-use control pad. No counter-top clutter and the ability to choose different levels of alkaline or acidic water veer a push button digital display at your fingertips. Well, please imagine no more. Introducing the world’s most advanced, under-sink, domestic water ionizer – the Delphi H2 from AlkaViva.

The AlkaViva Delphi H2 looks complicated, is it convenient and easy to use?

Convenience is critical in designing the ideal ionizer. From the beginning the Delphi was designed as a specialty undersink unit. Under the counter is a most advanced ionizing unit. Above the counter is an elegantly designed faucet with a beautiful and discreet LCD display. No ionizer is easier to use than the Delphi H2. A light finger touch on the faucet control pad selects your preferred level of acidic, filtered or alkaline water. The LCD display shows you the water level selected and the life of the filter (in ionizer below counter).

How powerful are the electrodes of the AlkaViva Delphi H2?

The Delphi comes from a top manufacturer of water cell technology and features the ultimate cutting-edge in electrode technology, the Delphi uses patented mesh electrodes that give an increased surface area. This means not having to increase the voltage that causes wear on the plates. The advanced technology protects the electrodes while increasing the efficiency. If you used a microscope to look at a mesh-plated electrode you would see numerous valleys and peaks of platinum titanium that are there to give you, year after year, the ultimate conductivity and durability. Some importers buy from assemblers (not true manufacturers) and use large cheap plates from China and elsewhere. They claim that large plates are the answer to better ionization and pH but since when has electronics become larger as it evolved? The Delphi has been especially designed to give you the best ORP at every levels of pH (as well as giving the big -ORP numbers at the higher pH ranges).

Can the AlkaViva Delphi H2 remove fluoride?

Yes! Through lengthy research and development the AlkaViva Delphi H2 uses the world’s best activated alumina media, removing fluoride throughout the life of the filter.
If you want to ensure your water is 99.9% fluoride free we recommend a fluoride pre-filter in tandem with our AlkaViva Delphi H2 unit, which specifically dose the single job of removing fluoride. See in line fluoride filter here.

What other contaminants does the AlkaViva Delphi H2 remove?

    ·  Heavy metals
     ·  Mercury
     ·  Lead
     ·  Aluminium
     ·  Copper
     ·  Bacteria
     ·  Pesticides
     ·  Algae
     ·  Fungi
     ·  PHarmaceuticals
     ·  Arsenic
     ·  & so much more

Is the AlkaViva Delphi H2 built to last?

Your water ionizer is an important investment that you want to last for many years. Inside the Delphi is the patented system that allows for your ionizer to be cleaned with every use (without you having to wait and without you noticing). This feature alone is a good enough reason to choose only AlkaViva ionizers as your preferred brand. All other brands on the market still use the old technology of reverse polarity to clean – which will create scale build up over time and a decrease in the electrode efficiency. With the Delphi you never have to give cleaning a second thought! Something else to consider is that just in the past three years about 8 new manufacturers have come and gone leaving their customers without technical support and with no place to buy filters. Our manufacturers supplies major companies such as Samsung, Toyo, LG and Hyundai. With their track record of giving quality service for over 35 years they are unmatched. In brief here are some of the many other Delphi features that are not mentioned above:
     ·  Inbuilt flow control valve to automatically control and create the ideal water pressure
     ·  Automatic temperature shut down if the cell gets too hot
     ·  Quality glass fuse to protect your investment in case of power surge
     ·  Adjustable voice confirmation that tells you the water level selected
     ·  Each Delphi H2 comes with a pH test kit for testing your water, an installation DVD, a beautifully illustrated manual and an installation kit

What are some test results for filters used in my AlkaViva Delphi H2?

Only AlkaViva has the confidence to test their water filters using an independent US EPA-Certified lab to ensure you are drinking not only alkaline water but clean and purified water with the best contaminant removal available. See test Delphi H2 filter testing results here

How many water settings dose the AlkaViva Delphi H2 have?

The AlkaViva Delphi H2 has eight (8) different water settings

What do the buttons of the AlkaViva Delphi H2 consist of and what do they do?

The AlkaViva Delphi H2 utilises five (5) settings for alkaline setting preferences ranging from, 1 through to 5. There is also two (2) settings for acidic preference and a single (1) setting for crystal clear purified water.

     ·  ACID 1 – This is a weak acidic water range with a pH. range of approximately pH.5.0 – 6.5. This AlkaViva Delphi H2 setting can aid in firming beautifully healthy skin. Human skin pH. positions its self within this pH. range naturally.

Can I adjust the pH of the Delphi H2 water?

All of the settings of AlkaViva Delphi H2 water can be controlled by flow rate to further adjust pH. We recommend a flow rate between low settings to high setting for the best performance. If you want a lower pH, simply decrease the flow rate. The AlkaViva Delphi H2 manual flow control valve, precisely regulates the flow rate, meaning you have no need to adjust the faucet’s flow rate. Just turn on the tap on and regulate pH within as required.

How well does the AlkaViva Delphi H2 improve pH?

The AlkaViva Delphi H2, pH performance is directly related to the input water. Always remember that tap water varies from suburb to suburb. The AlkaViva Delphi H2 performs superbly in all fresh water types supplied by government regulated facilities. AlkaViva Delphi H2 will consistently produce water ranging from 7.5- <11. The bottom line; more acidic input water will have a lower pH, more alkaline input water will have a higher pH but both may be adjusted using the flow control valve. AlkaViva Delphi H2 also re-infuses input water with healthier levels and proportions of alkaline minerals (as well as ionizing the water). AlkaViva utilises our decades of filter experience to ensure the life of the filter, so you have excellent purity and performance from start to finish. Those who utilize bore water here in Australia, should also expect great performance. Very often, bore water starts a bit above 7.0 and this can also translate to higher pH outputs from your AlkaViva Delphi H2.

How do I install the AlkaViva Delphi H2?

The way to install the AlkaViva Delphi H2.

Under sink – the attention-grabbing AlkaViva Delphi H2 on the counter. For you, we have an under sink option available which includes all the connecting pieces and a separate dedicated faucet to drink from. Installation doesn’t require a plumber, but if you’d feel more comfortable using one, go ahead. As usual, we’ve sourced the specially designed faucet from the best water filter engineer in the US, so there’s no need to worry about lead. Please note that we cannot be responsible for the efficacy of your under sink installation. Here is the manual you need to complete the installation/under sink Install Instructions.

Can I connect the AlkaViva Delphi H2 to my existing Reverse Osmosis?

Yes, the AlkaViva Delphi H2 can be connected in series with an RO system. It will add powerful alkalizing and ionizing abilities to your acidic and aggressive RO water. You could also remove the RO system completely and replace with the AlkaViva Delphi H2.

How long is the AlkaViva Delphi H2 warranty?

The warranty for the AlkaViva Delphi H2 five (5) years for parts and labour under normal use when you register your warranty on the AlkaViva website. Warranty does NOT cover replacement cartridges as there are too many variables in source water. AlkaViva dose create the Delphi H2 to have a life span of <15years

Will my AlkaViva Delphi H2 be out of date in a year or so?

When you change your filters, you get a brand new one, which will incorporate any updated technology we have implemented. That’s why your Delphi H2 will never be out of date.

How important is the water I supply (source water) to my AlkaViva Delphi H2?

Performance levels are significantly impacted by source water – whether you are talking about H2 or pH and ORP. If you test any ionizer using hard water with elevated levels of TDS and alkaline minerals, it will always give its best level of performance. Conversely, if you test the exact same ionizer on soft water it will always give less performance.
When discussing water quality it is also important to note that water quality changes throughout the year in most locations, which can cause different test results. Any performance comparison is invalid unless the exact same source water is used.

Is it better to have a fast or slow rate of water?

AlkaViva Delphi H2 Ionizer’s flow rate will affect performance. All things being equal, an ionizer with a slower flow rate will produce more performance. You can also slow the flow on an ionizer and achieve higher performance. Slowing the flow will also typically raise pH,. Our Vesta H2 offer the convenience of an excellent flow rate and on-board flow control valves and a real time flow meter display which help you achieve the perfect balance between the flow rate and the hydrogen / pH performance you want.

Is it important to clean the electrodes?

As with any water ioniser, to achieve optimal performance the electrodes must be kept clean. Therefore how well an ionizer’s cleaning system performs its function is critical. If you have hard water after your ionizer has formed scale on the electrodes, you will return lower performance results. The AlkaViva Delphi H2 includes our DARC cleaning which has a 9-year track record as the best cleaning system in the industry. We have always approached the power issue with the belief that if you have advanced electrode design and manufacturing, then apply the right amount of power, you’ll get efficiency and performance. Our H2 ionizers run 150 watts of peak power ensuring long plate life.

What makes the Delphi H2 better than other ioniser’s I’m researching and available in the market today?

Please be sure to note the different source waters and resulting results. All in all, the Vesta H2 is a stellar performer in hard or soft water. What is better is you can achieve excellent H2 results on lower alkaline settings and lower ph.





Most ionizers will not produce any hydrogen water at lower power settings. All other features and benefits aside, we think the Vesta H2 is unique in our industry just for that reason.

Chart above depends on your water source

So as you can see, the AlkaViva Delphi H2 Ionizer produces excellent H2 / diatomic hydrogen/ hydrogen water in a wide range of water quality situations. From the tests you can see it can produce good H2 at lower, safer and better tasting pH levels.

Engineered with DARC cleaning and a super-efficient plate/power combination ensuring our AlkaViva Delphi H2 water ionizers will keep high performance for longer than other ionizers.

AlkaViva Australia will remain true to our long time philosophy of communicating with transparency and accuracy – as we perfect our filter technology year by year we will only offer the very latest and best at all times, so stay tuned!
