Advanced Molecular Hydrogen Technology
The Delphi H2 uses AlkaViva's Hydrogen Infusion Technology and nine platinum-coated titanium electrodes to produce molecular hydrogen (H2) during electrolysis.
Hydrogen production and pH levels depend on your source water, mineral content, flow rate, and selected settings. The Delphi H2 allows you to adjust water levels to suit your preferences and local water conditions.
Automatic Cleaning and Hard Water Protection
The Delphi H2 features advanced automatic electrode-cleaning technology designed to help minimize calcium deposits and maintain performance.
Its reinforced construction and automatic cleaning provide additional protection for everyday operation. However, very hard water may still require pretreatment or scale protection. Contact us if you are unsure about your water conditions.
UltraWater Filtration and Water Quality
The Delphi H2 includes AlkaViva's dual UltraWater filtration system, designed to reduce a wide range of water contaminants while retaining naturally occurring dissolved minerals.
UltraWater filtration has been independently tested for 249 contaminants. Specific reduction performance depends on the contaminant, filter configuration, water quality, and operating conditions.
