Enagic® (Kangen™) machines work well—until they don’t. Their outdated cleaning system requires you to run citric acid cleaning cartridges and do yearly deep cleanings—or you risk voiding your warranty. We can professionally clean your Enagic machine for just $50 (you cover shipping). We'll get it done right and in less than one week (Enagic service takes 3–5 weeks / $50)
No required maintenance. No cleaning hassles. A better warranty. AlkaViva’s next-gen H2 Series Water Ionizers deliver it all. AlkaViva’s next-gen H2 Series Water Ionizers deliver:

The world of water ionization has come a long way. Enagic helped pioneer this space decades ago, and for that, we’re grateful. But technology doesn’t stand still. Just like we’ve moved from rotary phones to smartphones, water ionizers have evolved too. At AlkaViva, we’ve embraced that evolution—developing systems that deliver cleaner water, more hydrogen, and smarter features, all while keeping your health and budget in mind.
Your water system should do more than just sit on your counter—it should work with your life. AlkaViva’s ionizers offer next-generation features like auto-cleaning, undercounter installation options, and UltraWater filtration, which removes over 249 contaminants. No complicated maintenance. No extra add-ons required. Just clean, healthy, hydrogen-rich water at the touch of a button.
1,000+ peer-reviewed articles on H2 show it offers health benefits in over 170 health conditions, positively impacting every organ of the body. .
Choose the right model for your needs — all with UltraWater filtration, advanced H2 performance, and honest pricing.
Over 1,000 peer-reviewed studies show that molecular hydrogen - or H2 - has a therapeutic benefit in every organ of the human body and positively affects over 170 disease models and health conditions.
Oxidative stress damages your cells, causing pain and inflammation. As we age, inflammation increases. Studies show that H2 neutralizes the damaging radicals. Drinking UltraWater can ease chronic and acute aches and pain.
Free radical damage causes oxidative stress and is one of the primary causes of aging. Oxidation causes iron or apples to “rust”. Antioxidants prevent or slow that damage. Unfortunately, anti-oxidants neutralize both beneficial and harmful radicals. Research shows the H2 in UltraWater specifically targets only the damaging radicals - making it the “ultimate” antioxidant.
ATP powers your cells. It is the source of your energy. Research shows H2 helps increase ATP production, giving you more energy while decreasing lactic acid levels. Athlete? Exerciser? Just want more pep? UltraWater helps improve performance and recovery.
When H2 neutralizes damaging oxygen radicals, it creates water (H2O) - increasing your cellular hydration. Great tasting and silky-smooth alkaline UltraWater is also easier to drink. When you drink more, you enjoy optimal hydration and better health.
UltraWater is alkaline and ionized, making it rich in naturally occurring beneficial minerals like calcium and magnesium that help you alkalize and maintain a healthy pH balance.
