Up to 3,000 PPB (3 PPM) of hydrogen in 3 minutes, verified by an independent lab

Honestly, Hydroh is the one I expected the least from. It was the cheapest serious bottle I tested, so I figured that's where they cut corners. I was wrong. It put out more hydrogen than bottles costing two and three times as much, and it's the one I still recommend to my clients.

Hydroh makes up to 3,000 parts per billion (3 PPM) of dissolved hydrogen, and it stayed consistent at 3 PPM every time I ran it. Research says you need at least 1.5 PPM to actually feel it, so you're getting about double.

It's IHSA certified too, so the hydrogen number was checked by an independent lab. A lot of brands just print a number on the box and leave it there.

You can use tap, filtered or purified water. You don't need mineral water or special cartridges, and there are no filters to replace.

Most of the bottles I tried are made of plastic, and a couple of brands wouldn't say what kind. Hydroh is glass and stainless steel, so your water only touches glass. I drink from it every day, so that mattered to me more than I expected.

It uses PEM/SPE technology, which you normally see in much pricier devices. It keeps chlorine and other byproducts out of the water during the cycle, so you're drinking clean water with the hydrogen in it and nothing extra.

At 15.2 oz, Hydroh holds almost twice as much as the Evolv. One bottle covers my morning. With a smaller bottle, you'd be refilling it four or five times a day to get the same amount.

A cycle takes three minutes. I fill it, press the button, and it's ready before I've finished making breakfast. Some of the other bottles need 10 to 20 minutes for one cycle.

Hydroh is normally $129.99, but it's been on sale for $69.99. That's half the price of the IonBottles Pro and about a third of what Evolv costs. Last time I checked, the sale was still on, but they say stock is limited.

You get 90 days to try it, and if you don't feel a difference, Hydroh gives you your money back. There's also a free 365-day warranty, and more than 3,800 people have left it a 5-star review. So trying it doesn't cost you much if it turns out it's not for you.

If you're curious about hydrogen water and want one bottle that just works, this is the one I'd tell you to get. It's easy to carry, easy to use, and one bottle gives you a real dose.

One heads-up: there are look-alike bottles out there. Get the original from the official Hydroh site, since that's where the sale price and the 90-day money-back guarantee apply.

Just make sure you get the original:

Decent hydrogen output in a bottle that only holds 8 oz

Evolv is a good bottle. The hydrogen output is decent, and it comes in a few colors. If it held more water, this would have been a much closer call against Hydroh. The problem is how little it holds.

Evolv holds just 8 ounces. To get a real dose in a day, you'd have to fill it, run it and drink it four or five times. I can't see many people keeping that up for long.

Evolv advertises 5.4 PPM, which sounds great. But it's 5.4 PPM in 8 ounces of water, so in total you're not getting more hydrogen than a bigger bottle gives you in one cycle. The amount you actually drink matters more than the number on the label.

Evolv starts at $199. That's almost three times the price of Hydroh on sale, for a bottle that holds about half as much water and needs four or five runs a day to do the same job.

A lot of that price seems to go into marketing. Evolv leans on big concentration claims and celebrity endorsements, and you end up paying for both.

If you love how it looks, I get it. But if you're buying it for the hydrogen, it's hard to justify the price.

If you only want a small hydrogen boost once or twice a day and the price doesn't bother you, Evolv does the job. It's well made, it fits in a small bag, and the timer display on the base is handy.

As your main water bottle for the day, though, it's just too small.

A good bottle with a size problem. At $199 for 8 ounces, it's hard to recommend over Hydroh at $69.99 with almost twice the capacity.

Handy carrying handle and a quick 3-minute cycle

IonBottles Pro is a decent bottle. It's portable, the carrying handle is handy, and a cycle takes three minutes. It looks like a serious option until you check how much hydrogen it actually makes.

IonBottles Pro tops out at 1.3 PPM. Research says you need at least 1.5 to actually feel it, so even at its best, this bottle comes up short.

Hydrogen is the reason to buy a bottle like this, so that's a big problem. You get some hydrogen in your water, just not enough to do what you bought it for.

For comparison, Hydroh reaches up to 3,000 PPB (3 PPM), about double the minimum.

At $139.99, IonBottles Pro costs twice as much as Hydroh on sale and makes less than half the hydrogen. Add their optional $70 protection plan and you're over $200 for a bottle that doesn't reach the minimum.

The build doesn't help either. For the price, it feels cheaper than it should.

If you mainly want a portable bottle with a handle and don't care much about hydrogen levels, it'll do. If you're buying it for the hydrogen, you can get a stronger bottle for less.

A quick 2-minute cycle, but outdated technology that could put your health at risk

HydroHealth is about as simple as it gets. You fill it, press the button, and two minutes later it's done, which was the fastest cycle of any bottle I tried. At $92, it's in the middle of the pack on price. The problem is what's inside: older technology that newer bottles have already moved past.

HydroHealth only works with mineral water. Tap water and filtered water aren't supposed to go in, so you'd be buying mineral water on top of the bottle every week for as long as you use it.

It's an easy detail to miss when you order, and it gets old fast.

HydroHealth only uses SPE electrolysis, an older setup that newer bottles have moved past. It's also the reason the bottle is so picky about the water you put in it.

Here's what worries me more. Older electrolysis can produce chlorine along with the hydrogen, and that chlorine can end up in your water. Be careful with that one, because this is the water you'd be drinking every single day.

HydroHealth advertises 1,600 PPB (1.6 PPM) of hydrogen. That's barely above the 1.5 PPM research says you need to feel anything, so there's very little room for error. I also couldn't find anything that backs the number up.

They also don't explain how the filtration works or what the bottle is made of.

I couldn't find any warranty information either. For an electronic device you'll use every day, that's a risk you carry yourself.

So for about $20 more than Hydroh's sale price, you get a lower hydrogen claim and a lot less information.

If you already drink mineral water every day and want the quickest cycle possible, HydroHealth could work for you. For most people, the outdated tech and the mineral water rule are hard to look past.

Large capacity and a direct connection to your tap

These are the big machines that sit next to your sink and hook up to the tap. They look impressive, they hold a lot of water, and they can run all day, so I understand why people want one.

Take away the touchscreen and the price tag, and what you've got is a very expensive water filter that makes alkaline water. Alkaline water isn't hydrogen water. Selling it as a health upgrade for thousands of dollars feels like a scam to me.

They do make a little hydrogen, but only about 0.6 PPM. That's well under the 1.5 PPM research says you need to feel anything. Hydroh reaches up to 3 PPM in a $69.99 bottle.

Counter-mounted systems cost four to six thousand dollars. For the price of the cheapest one, you could buy more than 50 of the best hydrogen bottles at the sale price.

Most of them need professional installation, take up a lot of counter space, and don't fit every faucet. Once it's installed, it stays in your kitchen, so you can't take it to work, to the gym or on a trip.

I wouldn't recommend one. It's an expensive filter with a small amount of hydrogen. A good portable bottle gets you more hydrogen for a fraction of the price, and you can take it anywhere.

$4k to $6k

The lowest prices in this roundup, but nothing to back them up

Search for hydrogen water bottles on Amazon or Temu and you'll find dozens of cheap ones. Some of them even copy the look of the bottles on this list. I get why the price is tempting, but it's the only thing they have going for them.

There's a reason they cost so little. A lot of them run on the same outdated electrolysis HydroHealth uses, just in a cheaper shell. That's the older technology that can put chlorine in your water along with the hydrogen.

So you're not really saving money. You're paying less for old technology, with even fewer answers than HydroHealth gives you.

None of them have been tested. Nobody knows if they produce any hydrogen at all, let alone the 1.5 PPM research says you need to feel it.

A number on a product listing doesn't prove anything. Without lab testing, you might just be buying an ordinary water bottle.

Nobody knows what the plastic is made of either. You'd be filling it with water and drinking from it every day, so this is the last place I'd try to save money.

I wouldn't recommend one. Unless you have money to spare and a specific reason to want one, a good portable bottle gets you more hydrogen for a fraction of the price, and you can take it anywhere.
