AlkaViva UltraDelphi Under-Sink Alkaline Water Ionizer Machine 

The AlkaViva UltraDelphi is one of the best under-sink water ionizers on the market today. The previous model, the Delphi, made its debut in 2007 and quickly became the leader in style, performance and durability for under-sink water ionizers. Then in 2016, it was upgraded to the UltraDelphi Under-Sink Water Ionizer.

For more information about the benefits of alkaline water, read our blog post here.

Product Features:

  • Healthiest Drinking Water: The UltraDelphi water alkalizer now comes with two filters - an external sediment filter (with housing) and the UltraWater filter housed internally. UltraWater filtration reduces contaminants up to 99.9% – even the toughest like pharmaceuticals, heavy metals, chemicals and VOCs. It is the only ionizer filter made in the USA and tested to rigorous standards. Click here for UltraWater Test Results.
  •  Convenience & Ease of Use: With one finger you can lightly touch the control pad on the top of the faucet to select the exact type of water you want. The elegant faucet has a beautiful LCD display that allows you to get both alkaline and acidic streams of water right at your sink. The under-sink model eliminates clutter on your counter and the automatic cleaning system makes it so that you never have to wait for water while the system cleans itself.
  • Reliable Automatic Cleaning System: The patented DARC Cleaning System of this under-sink alkaline water ionizer eliminates the scale buildup that deteriorates performance in other water alkalizer brands.
  • Quality Performance: In 2006, AlkaViva launched their Mesh Diode Electrodes and started the "mesh revolution". The right power and the right electrode are critical components of a quality ionizer. The new and improved UltraDelphi water alkalizer boasts a 20% to 30% stronger performance.
  • Quality pH and -ORP Performance: The UltraDelphi not only produces consistently higher levels of Hthan other under-sink brands but will also (depending on source water) create up to a 10.5+ pH and -800 ORP.  
  • The Greenest Environmental Footprint: Even with the updated power ratio, the UltraDelphi still offers greater efficiency, meaning it uses less electricity than other brands, creating a smaller environmental footprint.
  • Filter Replacement Reminder: An alert will flash on the LCD display control panel letting you know when the filter needs to be changed.
  • Adjustable Voice Confirmation: The UltraDelphi speaks to you, telling you what type of water you have selected each time you use the system.
  • Elegant Design: The quality finish on the UltraDelphi faucet tower will enhance the look of any kitchen. Designed from the start as an under-sink alkaline water ionizer, the UltraDelphi water alkalizer has both a state-of-the-art under-sink water ionizing unit and an elegantly designed sink-side faucet.

Our Story

Our CEO understands first-hand the need for clean water in the US and around the world.

That's why it is our company's mission to deliver clean water products to our customers while also supporting clean water charities around the world.

She also has her own family, including two little girls under age 2, to think about and provide for. Children are the most susceptible to contracting diseases from bacteria and viruses.
