The H2 Series
The focus on water ionizer performance is shifting to now include hydrogen (H2) along with alkalinity (pH) and ionization (-ORP).
Why the H2 Series Water Ionizers are the Best.
The Safety of UltraWater Filtration
The focus on water ionizer performance is shifting to now include hydrogen (H2) along with alkalinity (pH) and ionization (-ORP). The water ionizer cell - the engine for creating hydrogen rich water - has two components: electrodes and (ion exchange) membranes. Performance has historically been focused only on the electrodes. H2Infusion Technology is based on the fact that membranes are as critical to water ionizer performance as the electrodes. Other alkaline ionizer manufacturers buy their membranes from outside sources. In comparison, our H2Infusion membranes are made in-house and are ultrasonically pressed rather than chemically bonded like everyone else’s. This provides you with a distinctly superior membrane, designed to work specifically with our electrodes, giving you a hydrogen water maker with unmatched performance. When you marry our advanced SmartDesign Electrodes to our H2Infusion Membranes, the result is H2Infusion Technology and that means better pH, -ORP and H2 performance – especially at the lower, better tasting pH levels most people drink.
UltraWater™: The Best Ionizer Filter
UltraWater is the ONLY water ionizer filter tested for 172 contaminants. Independent EPA-certified lab testing shows that AlkaViva's UltraWater is the ONLY ionizer filter to reduce virtually all contaminants to 99.9% - even the toughest. Clean, smooth, and safe, our water tastes great and is easy to drink!
New and Improved DARC II Cleaning
Clean electrodes are critical to performance. Our DARC II system cleans your H2 water ionizer with every use. This helps ensure that the electrodes stay free of damaging scale buildup. It also runs automatically, in the background, so you never have to wait for a cleaning cycle to get clean and healthy UltraWater.
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.
Advanced Smart Electrodes
We do not believe in over-sized or over-powered electrodes, which are often a sign of older style, inefficient design. Our water ionizers' Smart Electrodes are engineered to deliver ideal pH, ORP and H2. Enjoy long-term performance along with absolute reliability and maximum efficiency.
Flow Control System
Optimal flow rate is critical to achieving optimal performance. The H2 Water Ionizer Series provides superior flow control with an LCD display so you can see and select the flow rate that's right for you.Featured Products
