Product Description

Undersink ionizer solutions are rarely as good as the Alkaviva Delphi H2 Ionizer, which has been released as an upgrade to the award winning Ultra Delphi Ionizer. This latest model offers excellent performance and utilises the same Hydrogen Infusion Technology as seen in the Vesta H2 model to set new standards for pH and ORP levels. That great performance is then combined with an intuitive and user friendly touchscreen faucet, for easy control over all the functions of the Delphi.

Optimal pH Levels

In terms of pH performance the Delphi H2 provides excellent levels that are nearly unmatched in the ionizer market. At its peak it is capable of producing water up to a pH of 12 and can then work through to levels as low as 2.1. Drinking water at such severely high or low pH’s is not recommended, but the Delphi H2 is even better at producing water in between the recommended pH levels of 8 and 9. At these levels it also manages an ORP of -800 and 1.3 H2, making for optimal drinking water that can be easily selected with the smart touchscreen faucet.

The Delphi H2 also boasts fantastic ORP (Oxidation-Reduction Potential) scores with readings of -900 becoming attainable at the highest pH settings and readings of around -800 being seen at the recommended pH drinking levels.

Exceptional Ionization

The Alkaviva Delphi H2 is only able to achieve such impressive pH and ORP levels thanks to the exceptional ionization performance achieved by its 9 SmartDesign plates. These plates are made of titanium with a further thin coat of platinum over the top. The use of these premium metals allows for efficient electron transfer to water molecules causing them to be ionized more evenly and effectively.

Alongside top quality construction, the plates in the Delphi H2 are designed to work more efficiently at lower levels of power than most other ionizers. This allows them to last for longer in comparison to less efficient models that typically struggle after just 18 - 24 months of use.

Additionally to its plates, the ion exchange membranes within the Delphi H2 have been optimised for the production of Hydrogen. Alkaviva ionizers always feature uniquely manufactured membranes, allowing them to achieve better performance and more consistent levels than those used in other models. The unique Alkaviva membrane design allows for them to work hand in hand with the electrode plates, ensuring perfect performance from the Hydrogen Infusion Technology.

Smart Faucet Design

The smart faucet used to control the Delphi H2 has a very sleek design and is perhaps one of the most intuitive ionizer interfaces seen in an undersink model to date. Most functions require just one touch to start up and Alkaviva have done a great job of not overcomplicating the interface, allowing it to maintain a compact form factor.

H2 Hydrogen Performance

The Delphi H2 doesn’t just offer great pH and ORP ratings, it is also excellent at producing high levels of Hydrogen (H2). Unlike many other ionizers that struggle to produce H2 the Delphi is able to achieve 1.6ppm. This makes for water that tastes nice while also being highly beneficial. In fact, over 500 studies have shown that H2 gives a therapeutic benefit in up to 140 health conditions, making it a very useful addition as part of the ionized mix.

Among the many benefits of H2 consumption, its incredible ability as an antioxidant stands out the most. This antioxidant property allows H2 molecules to combat free radicals in the body, which cause oxidation of cells. That oxidation process translates into the aging of skin, so the more antioxidants there are in the body the less it will show signs of age. H2 in particular acts as a great antioxidant as it targets specifically any damaging free radicals, leaving any useful radicals unharmed.

H2 also offers many other advantages to the body including an increase in energy and reduced muscle fatigue. These allow the body to feel energised and reduce any signs of damaged muscles and reduced performance. Furthermore, H2 is a great way to improve hydration, as when it neutralises oxygen radicals, they are combined and transformed into water molecules.

UltraWater Pre-Filtration

As part of the ionization process, the Delphi has a 13-stage dual water filtration system that uses UltraWater technology to filter out a variety of water contaminants. When installed the UltraWater filters remove Chlorine, Lead, Arsenic, Copper, Manganese and VOC’s (Volatile Organic Compounds) to untraceable levels. This ensures that when the water is ionized, no unexpected chemicals can interfere with the process, which would be the case with a cheaper carbon filter.

Useful Functions

The Delphi has many great functions to help it stand out against other ionizers. One of the most appealing of these functions is the fully automatic DARC (Dual Automatic Reverse Cleaning) cleaning system, which cleans the ionizer with every use through polarisation, keeping the electrode plates free from scale. Scale is one of the largest issues faced by ionizers and it vastly reduces their performance over time. Therefore, the patented DARC system is integral in allowing the Delphi to stay in top condition for a long time.

On top of its cleaning system the Delphi also makes use of a real-time Flow Control System. This system is controlled through a valve, which can be adjusted for precise flow rate control. All flow speed information can be seen clearly on the LCD display, allowing for a clear visualisation of any flow changes. Getting the right flow is crucial to achieving the desired pH, ORP and Hydrogen levels, so such easy adjustment proves to be useful for the best results.

Finally, this ionizer has an AutoAdjust system, which allows power settings to be adjusted to the optimal level for different types of water. This process ensures peak PH, ORP and Hydrogen performance with every use of the Delphi H2.
