Ondea U1 | Under-Sink Water Ionizer with Smart Faucet

All the benefits of ionized water, none of the countertop clutter

The Ondea U1 installs neatly under your sink and delivers filtered, pH-adjusted water through a sleek dedicated faucet. All controls sit right on the faucet itself, so switching between alkaline, purified and acidic water takes a single touch. Your countertop stays clear, your kitchen stays calm.

One faucet, every type of water

Select your setting on the faucet display:

• Alkaline water in multiple levels for everyday drinking, coffee and tea, and rinsing fruit and vegetables
• Purified neutral water for taking medication or preparing food for little ones
• Acidic water for skincare rinsing, household cleaning and plant care

Filtered at the source

Before ionization, water passes through the built-in activated carbon filtration that reduces chlorine, unpleasant tastes, odors and organic impurities. The system tracks filter life for you and signals clearly when replacement is due, so water quality is never a guessing game.

Powerful electrolysis, zero maintenance

Inside the under-sink unit, platinum-coated titanium electrode plates split the incoming water stream into alkaline and acidic components with consistent precision. An automatic self-cleaning cycle keeps the electrolysis chamber free of scale buildup, maintaining full performance year after year without any effort on your part.

Designed for homes and hospitality

With its discreet installation, intuitive faucet controls and durable build, the Ondea U1 is equally at home in family kitchens, rental properties and hotel suites. Guests and household members alike simply tap and pour.
