Know Your Water
They know what’s really in our water
You can't see or taste the scariest contaminants. Your water looks and tastes fine. But it isn’t. And the EPA knows it. We accessed the EPA’s ECHO Database1 to show you what they know. About your water. Here are some startling facts about public water in the USA:
157 million of us drink Forever Chemicals
Also known as PFAS, they are dangerous because they “last forever” and are highly toxic - even in minute amounts.
276 million of us drink lead
That’s 81% of Americans! Lead causes developmental issues, cognitive issues like memory loss and kidney damage.
314 million of us drink Chromium VI
The carcinogenic “villain” chemical in the movie Erin Brockovich. It damages internal organs, the respiratory system, and skin.

Hi, I'm Susie. I have been drinking ultra water for over 18 years, and I can't begin to tell you the benefits. It's really helped me out a lot in regards to my inflammation that I used to have in my hands. So I do have, you know, arthritis that's not apparent anymore. And then also what it's done for my skin, my energy level, my hair. It's just been tremendous. And there's all kinds of different uses that you can have, you know, with the acidic water, not as well, just not the alkaline water. And also, too, do not forget about your critters, because your critters also benefit from the water, and it helps promote longevity of their, their lives, too. So we want to try to spend as much time as we can with them. All right. Thank you. Give us a try.

Over 20 years ago, while living on the east coast, I contracted Lyme disease and began to suffer with brain fog, headaches, inflammation, and joint pain. Because the disease was so misunderstood at the time, it often went misdiagnosed and mistreated. Fortunately for me, I was able to find a naturalistic doctor who properly diagnosed my symptoms as Lyme's disease, and she helped me to make some lifestyle changes that really, really made a difference in how I felt. One of the things that I was able to add to my life was a water ionizer from alkaviva. It produces alkaline ionized hydrogen water, which has the ability to greatly reduce the symptoms from which I was suffering. So if you are on the fence about buying one of these machines, put the thing in your cart, hit the buy button and go for it. You won't regret it, I promise.

Hi, I'm Frannie Welter, and I've owned an Alkaviva water ionizer for over 15 years. Started off with the Athena and just switched over to the amazing Delphi model, which also hydrogenates the water. So many health benefits. But let me just show you this beautiful unit right here. I've worked up to an alkaline three. Absolutely beautiful. To learn more about all the benefits of purifying and alkalizing your body with this water, check out Alkaviva Caddy.

Frequently Asked Questions
Everything you need to know before choosing an AlkaViva water ionizer.
Still have questions?
Talk with an AlkaViva water expert
Which AlkaViva water ionizer is right for me?
Compare the 13-plate Delphi H2, 9-plate Delphi H2 and 7-plate Athena H2 above — or talk with a water expert who will match a model to your water, household size and budget.
Is AlkaViva better than Kangen, Tyent, or Life Ionizers?
AlkaViva publishes EPA/NELAP-accredited lab results, prices without distributor markups, and backs every ionizer with a limited lifetime warranty. See the full comparison for a feature-by-feature breakdown.
Do AlkaViva filters really reduce PFAS and arsenic?
Yes. UltraWater filters are tested against 249 contaminants — including PFAS, glyphosate, lead and pharmaceuticals — and reduce them by up to 99.9% in EPA/NELAP-certified laboratory testing.
What’s the difference between the alkaline and acidic water streams?
The alkaline stream is your drinking water — ionized, hydrogen-rich and silky smooth. The acidic stream is for topical and household use: skin care, mouthwash, wound care, cleaning, plants and cut flowers.
