I have a soft spot for cool gadgets, especially the ones that make staying hydrated more interesting. A hydrogen water bottle is a gadget like that. It’s a high-tech piece of gear that’s been gaining popularity, yet most people have no idea how it actually works.
I’ll be honest, when I first got into this, I had no clue either. And yet, somehow, I still managed to drop $450 on hydrogen water bottles before really understanding what I was paying for.
So, let’s make sure you don’t go in blind like I did. In this guide, I’ll break down what hydrogen water is, how these bottles work, and whether they’re actually worth your time, all in the simplest terms possible.
What Is a Hydrogen Water Bottle?
A hydrogen water bottle is a special kind of bottle that infuses regular drinking water with molecular hydrogen (H₂) using a process called electrolysis.
Inside the bottle, there’s a small but powerful electrolysis system that makes it possible.
These bottles are usually USB-rechargeable as well, and come with a built-in battery, making them convenient for daily use.
Electrolysis: The Crucial Process
Let’s focus more on this electrolysis process because without it, your hydrogen bottle is just a bottle.
Electrolysis works by sending an electric current through the water, splitting it into hydrogen (H₂) and oxygen (O₂).
The hydrogen gas is then dissolved into the water (you know, all these cute bubbles), while the oxygen is usually released or separated through a small vent to ensure that only PURE hydrogen remains.
If you look at my Piurify Hydrogenator, you’ll see this vent at the bottom of the bottle. The oxygen is released through that vent, but it’s a completely silent process, and if you put your hand there, you won’t feel a thing.
Electrodes
What makes this electrolysis process very effective is the use of high-quality electrodes, typically made from platinum-coated titanium or SPE (Solid Polymer Electrolyte) membranes, which prevent unwanted byproducts like ozone or chlorine from contaminating the water.
If you’ve ever browsed hydrogen water bottles, you’ve probably stumbled across these terms and thought, What does any of this even mean?
Well, now you know—they’re the key players in the whole electrolysis process.
And if you’ve ever wondered why these bottles cost so much, this is your answer. Good electrodes aren’t cheap to make. That’s where most of the cost comes from.
How to Activate the Electrolysis Process?
Activating the electrolysis process is just a click of a button in my Piurify. However, it’s worth knowing that most hydrogen water bottles offer two or even more electrolysis programs.
My Piurify bottle offers two programs: one for 5 minutes and another for 10 minutes that generate up to 3000 PPB.
Now we can smoothly proceed to explaining what this PPB is.
PPB & PPM
PPB (parts per billion) and PPM (parts per million) are another unclear terms you’ll see on a hydrogen water bottle.
People are confused when they see them, but they’re just ways to measure how much molecular hydrogen (H₂) is dissolved in the water.
1 PPM means that for every 1 million parts of water, there is 1 part of hydrogen gas.
Similarly, 1 PPB means that for every 1 billion parts of water, there is 1 part of hydrogen gas.
Since a billion is 1,000 times more than a million, 1 PPM is equal to 1,000 PPB.
Most hydrogen water bottles measure their hydrogen concentration in PPM, with good ones typically producing between 1 to 3 PPM of dissolved hydrogen.
If you ever see PPB instead, just remember that 1,500 PPB is the same as 1.5 PPM, so it’s just another way of saying the same thing.
The Final Product: Hydrogen-Rich Water
After just a few minutes of this electrolysis process—anywhere from 3 to 10 minutes, depending on the model—you end up with hydrogen-rich water that is believed to offer various health benefits.
Some studies suggest that molecular hydrogen acts as an antioxidant, potentially reducing oxidative stress, improving hydration, and even boosting energy levels.
I’m one of a few people on earth who test these claims on themselves and document it, and after a year of testing I’ve noticed some real improvements in my energy and stamina (which is great because I play soccer as a hobby).
But the biggest improvement I saw is about my skin for some reason. You can read about my experiences more in my Piurify Hydrogenator Review.
Do Hydrogen Water Bottles Run Out of Hydrogen?
The quick answer is no, my hydrogen water bottles don’t run out of hydrogen.
I’ve tested the concentration with special hydrogen drops more times than I can count, and even after a year of using my Piurify Hydrogenator, the levels are still the same.
Now, does that mean every hydrogen water bottle holds up just as well? Can’t say.
What Is the Life Span of the Hydrogen Water Bottles?
From what I’ve seen, hydrogen water bottles don’t need to be replaced that often, at least the good ones. If you’re spending at least $100 on a quality model, you can expect it to last for years.
I’ve been using my Piurify for over a year, and I expect it to last for many more years to come. In fact, I’d argue they’ve held up better than some of my regular reusable bottles—and those don’t even have any fancy tech inside.
The one thing you do need to watch out for is the base. If you want your bottle to keep working, do not submerge it in water.
Final Thoughts
By now, hydrogen water bottles should no longer be a mystery to you. At least, that’s the goal! When you’re dropping serious cash on a high-tech gadget, it helps to actually know what you’re getting into.
