To determine the best hydrogen water machine, I looked at 28 different products and compared them using Drinking Water’s seven-point research methodology. I also benefited from the unique expertise of James Layton, our in-house water treatment expert with 25 years of experience working for water filter companies and consulting for regulatory groups, such as the EPA. 

Together, we determined the Piurify Water Hydrogenator is the best hydrogen water machine on the market. My second and third choices are for gym goers and athletes needing a portable hydrogen machine and a deluxe all-in-one unit that costs more money but comes with some unique features. Here’s more information on all the products that made my final list:

Best Overall: Piurify Water Hydrogenator (9.5/10)

  • Proton exchange membrane (PEM) electrolysis infuses more than 1,300 ppb of hydrogen into your water.
  • Built-in calcium sulfite filter and Vortex aeration remove chlorine and VOCs and also boost hydrogen levels.
  • The 1.5-liter pitcher size is large enough even for families.
  • Multiple hydrogen levels, touch screen controls, and self-cleaning feature simplify use.
  • Industry-best lifetime warranty reinforces product quality.
  • Best for everyday use but not for intense exercise or athletics
  • No removal of heavy metals, herbicides, pesticides, and other common contaminants

The Piurify Water Hydrogenator is my #1 recommendation for a hydrogen water machine because it infuses up to 1,300 ppb of hydrogen into regular tap water while also removing other harmful contaminants and is backed by an industry-best lifetime warranty.


The Piurify Water Hydrogenator is the best hydrogen water machine on the market for the following five reasons:

Pro 1/5: Infuses more than 1,300 ppb of hydrogen into your water

The first reason the Piurify Hydrogenator is the best is that it does what it says it can do and infuses regular tap water with more than 1,300 parts per billion (ppb) of hydrogen water

It does this using proton exchange membrane (PEM) electrolysis, which is a chemical process that uses electricity and a special membrane to separate hydrogen and oxygen from water molecules. PEM electrolysis is an improved version of the traditional electrolysis that allows for the production of ultra-high purity hydrogen. This high-quality form of hydrogen is then infused back into your water for you to consume. Using PEM electrolysis allows for higher concentrations of hydrogen into your water, which increases the potential antioxidant capacity of hydrogen-rich water.

This means that if you want a hydrogen machine that will produce enough hydrogen to combat aging and disease, you should get the Piurify Water Hydrogenator

Pro 2/5: Built-in filter removes chlorine and preserves hydrogen

The second biggest upside of the Piurify Water Hydrogenator is that it removes chlorine and chloramine from your water using a filter that also preserves your hydrogen-rich water

It does this with the included calcium sulfite filter, which is a chemical substance known to react with chlorine and chloramine and remove them from water. Few other hydrogen water machines include this step, an omission that reduces the overall quality of the water they produce. Including this feature also makes the hydrogen water generated by this machine last longer. The reason is that chlorine will react with the extra hydrogen molecules in your water, removing the hydrogen and leaving a potentially dangerous substance in its place. Since virtually every city water supply in the world has chlorine in it, the inclusion of this filter makes this hydrogen machine stand out. 

The Piurify Water Hydrogenator will also remove volatile organic compounds (VOCs) from your water thanks to its vortex aeration. This is a fancy way of saying the machine spins your water, creating an air tunnel that speeds up the vaporization of VOCs and forces them out of your water. No other hydrogen water machine includes this feature and it’s something that really helped it stand out from the competition.

All of this means that if you want a hydrogen water machine that produces not only hydrogen-rich but also clean and safe water, you should get the Piurify Water Hydrogenator.

Pro 3/5: 1.5-liter pitcher size

The third biggest pro of the Piurify Water Hydrogenator is that it uses a pitcher design that can hold up to 1.5 liters (just under a half gallon) of water. 

The vast majority of hydrogen water machines on the market use a water bottle design, which is great for portability and also because they can produce higher concentrations of hydrogen (see next product on my list). But they only produce around 8–12 oz. of water at a time. You don’t need to drink hydrogen water all day to be able to enjoy its benefits, but the size of this pitcher means you can generate the water once or twice and that will be enough for your entire family.

This means that if you want a hydrogen water pitcher that is large enough for everyday use and can meet the needs of both an individual and a family, you should get the Piurify Water Hydrogenator.

Pro 4/5: Special features allow for customization and ease of use.

The fourth pro of the Piurify Water Hydrogenator is that it includes several special features that allow for customization and ease of use

The first special feature is the option for “standard” or “high” hydrogen protection. The “standard” mode will result in water with around 700–900 ppb of hydrogen and takes just eight minutes. The “high” mode will boost hydrogen production to more than 1,300 ppb and takes around 14 minutes. The benefit here is that if you don’t have time to wait for full hydrogen infusion, you can select the “standard” option and get hydrogen water faster

The next special feature is the self-cleaning mode. This should be done after every 10 uses and takes just a few minutes. All you have to do is fill the pitcher with water and push the “self-cleaning” button on the front of the device. During this process, water is flushed through the calcium sulfite filter to flush out any trapped contaminants. When the machine is done, you need to remove the filter and rinse it with tap water. No other hydrogen water machine on the market has this feature and it ensures the water you drink is as clean and hydrogen-rich as possible

This means that if you want a hydrogen water machine with added features that let you customize your water and make the machine easier to use, you should get the Piurify Water Hydrogenator

Pro 5/5: Lifetime Warranty

Hydrogen water machines offer a lot of promise when it comes to improving health. But if they don’t work, you can’t experience these benefits. And since these things are not exactly cheap, buying something that breaks in a year or two is pretty much the worst-case scenario.

This is why the biggest upside of the Piurify Water Hydrogenator is its lifetime warranty.

Hydrogen water machines are still quite new, and the market is saturated with absolute junk. For example, virtually every product you find on Amazon is not worth your time, and the best warranty you might find is one year. The Piurify Water Hydrogenator, on the other hand, is backed by an industry-best lifetime warranty because it’s built to last and does what it’s supposed to do. And in the event something does go wrong, Piurify has got your back and will make the situation right.

This means that if you want to buy only one hydrogen water machine in your life and buy it from a company that stands by its products, you should buy the Piurify Water Hydrogenator.


The Piurify Water Hydrogenator is an excellent product but it has two major drawbacks:

Con 1/2: Not enough hydrogen for intense exercise

The first downside of the Piurify Water Hydrogenator is that while it infuses water with 1,300 ppb of hydrogen water, this isn’t really enough to make full use of hydrogen’s anti-inflammatory potential. 

The scientific community has yet to come to a full consensus on just how much hydrogen should be in your water and just how much of an effect it has. But a number of studies, including this one conducted by researchers at the University of Extremadura in Spain, found that drinking water with 1,900 ppb of hydrogen can help in anaerobic exercise and improve performance. Unfortunately, this is considerably higher than what the Piurify Water Hydrogenator can produce. However, the 1,300 ppb of hydrogen is still an effective dose for antioxidant purposes.

This means you can still experience the benefits of hydrogen water using the Piurify Hydrogen water machine. But if you want to use hydrogen water to aid your exercise regimen, you may want to look at the next option on my list.

Con 2/2: Filter does not remove heavy metals, herbicides, pesticides, and other contaminants.

The next downside of the Piurify Hydrogen Water Machine is that the included calcium sulfite filter does not remove many of the other contaminants that are possible or even likely to be in your water. 

It’s designed to filter out chlorine and chloramine, but if your tap water is contaminated with heavy metals, herbicides, pesticides, disinfection byproducts, forever chemicals, etc. this unit will not remove them. The best thing to do is to test your water, or, if you use city water, you can contact your local water authority to see what’s actually in the water you drink. 

All of this means if you’re looking to filter water and infuse it with hydrogen, you may need to purchase a water filter separately and then infuse the filtered water with hydrogen. Here are some links to reviews that might help you if this is the route you want to go:

However, the ability of this machine to remove chlorine and chloramine should make it an effective comprehensive solution for most of you.

OVERALL: 9.5/10

The Piurify Water Hydrogenator is the best overall hydrogen water machine on the market because it infuses water with 1,300+ ppb of hydrogen and includes a large pitcher. 

It’s true the filter only tackles chlorine and chloramine and not other common city water contaminants, but it does come with a lifetime warranty, the best in the industry.

If you want to start taking advantage of the potential health benefits of hydrogen water using a powerful, effective, and well-built hydrogen machine, you should get the Piurify Water Hydrogenator.

Best Portable: Piurify Hydrogenator Bottle (9.1/10)

  • Infuses water with up to 3,000 ppb of hydrogen in 10 minutes.
  • Includes nasal cannula for direct inhalation of hydrogen gas.
  • Made with high-grade durable plastics.
  • Comes with a lifetime warranty.
  • Limited capacity of 280 ml
  • Not a filter

The Piurify Hydrogenator Bottle is my top choice for a portable hydrogen water machine because it infuses extremely high levels of hydrogen gas into your water into a compact bottle that is backed by a lifetime warranty.


The Piurify Hydrogenator Bottle is the best portable hydrogen water machine for the following four reasons: 

Pro 1/4: Infuses water with up to 3,000 PPB of hydrogen

One of the biggest reasons the Piurify Hydrogenator Bottle scored so highly in my ranking is that it infuses water with up to 3,000 ppb of hydrogen in just 10 minutes

It does this using polymer exchange membrane (PEM) electrolysis, which is the same method used in the Piurify Water Hydrogenator I chose as my #1 choice for this review. It’s an improved method of electrolysis that helps produce hydrogen that is 99.99% pure, which is then infused into the water for you to drink. By infusing your water with up to 3,000 ppb of hydrogen, the Hydrogenator outperforms every other competing product on the market, including the Hydroh bottle, a popular product that has a max infusion of just 1,300 ppb

It takes 10 minutes to infuse water with 3,000 ppb, but if you’re short on time you can select the five-minute program, which infuses your water with 1,600 ppb of hydrogen.

This means if you want to get the most amount of hydrogen into your water so you can recover faster from workouts and experience the anti-inflammatory effects of hydrogen water, you should get the Piurify Hydrogenator Bottle.

Pro 2/4: Includes nasal cannula for hydrogen inhalation

The second positive of the Hydrogenator bottle is that it comes standard with a nasal cannula so that you can inhale hydrogen gas directly.

A cannula is a tube that connects to your nose so you can breathe in the gas. Numerous studies have found that inhaling hydrogen gas directly can help protect the lungs in a number of ways and can also have anti-inflammatory and antioxidant impacts in the rest of your body. 

If you want to level up your intake of hydrogen gas and consume hydrogen not only in water but as a gas, which is potentially more powerful, you should get the Piurify Hydrogenator Bottle because it allows for both methods of hydrogen intake.

Pro 3/4: Made with high-grade durable plastics

The third biggest upside of the Piurify Hydrogenator is that it is made from high-quality materials that are built to last

There are a number of less expensive versions of this device on the market. But not only did they not pass our tests in terms of hydrogen production, they also fell short in terms of build quality. The plastic used in the Hydrogenator is commercial food-grade plastic, meaning it’s scratch resistant and dishwasher safe. Most of these less expensive models are prone to scratching and warping and will likely need to be replaced after one or two years.

This means if you want a high-quality water bottle that also infuses your water with higher levels of hydrogen than any other hydrogen bottle on the market, you should get the Piurify Hydrogenator Bottle.

Pro 4/4: Comes with a lifetime warranty

A hydrogen water bottle like the Piurify Hydrogenator is designed to help you take advantage of hydrogen water (and gas) so you can live healthier and potentially longer. But if it breaks after a year or two, then it’s not really all that useful. And considering these things aren’t cheap, the last thing you want is to have to keep replacing these bottles every other year or sooner. 

That’s why perhaps the biggest selling point for me on the Hydrogenator bottle, and the reason it ranks so highly on my list, is that it comes with a lifetime warranty. This says to me that the company has built something that will last, and if something does go wrong, they will have your back and make it better. 

I was somewhat appalled by how cheap and poorly made the many hydrogen water bottles you can find on Amazon are, which explains why none of them offer more than a one-year warranty. In a world where things are made to break and be rebought on a cycle, Piurify took a different path and made something you’re going to have for a long, long time. 

All of this means that if you want a hydrogen water bottle that comes with industry-leading company support and commitment, you should get the Piurify Hydrogenator Bottle


I must mention two major drawbacks of the Piurify Hydrogenator Bottle:

Con 1/2: Only holds 280 ml of water

The first downside to the Piurify Hydrogenator is that it only produces and holds 280 ml, or approximately 8 oz of hydrogen water.

The company itself says you should drink between 500 and 1,000 ml of hydrogen water per day to experience its full effect, and also that you should drink the water right after it’s been infused with hydrogen. To be able to use this bottle and get this quantity of hydrogen, you will have to run the electrolysis process two to four times per day. And since it takes 10 minutes to infuse the water with 3,000 ppb, that can add up to a substantial amount of time just to produce the water you need to drink. 

It can be easy to work around this if you plan ahead. For example, after your workout, fill the bottle and turn it on. Then jump in the shower. When you’re out, the water will be ready for you to work. But this might not be realistic for all of you.

All of this means that if you’re looking for an all-day solution, the Piurify Hydrogen Water Machine I chose as my #1 recommendation is likely going to be a better solution.

Con 2/2: Does not filter water

The other con of the Piurify Hydrogenator is that unlike the larger pitcher model ranked #1 on this list, it does not filter water in addition to producing hydrogen. 

The unit is simply too small and would no longer be portable if it were to include this function. The solution is to make sure to fill the water with filtered water, either from a pitcher, from your fridge, or from your tap if you use a whole-house water filter. 

This is one of the tradeoffs for having a smaller unit that is portable and also capable of producing more hydrogen. For athletes and those of you who live life on the go, this might not be a major concern. And most of us have made it this far drinking water from our taps. But if you’re looking for a hydrogen water machine that will also filter and purify, then this may not be the hydrogen machine for you. I would look at the Piurify Water Hydrogenator Water Machine ranked in the top spot on this list.

OVERALL: 9.1/10

The Piurify Hydrogenator Bottle is my #2 overall recommendation and my top choice for a portable hydrogen water machine because it infuses water with an industry-best 3,000 ppb of hydrogen and also includes a nasal cannula for direct inhalation of hydrogen gas.

It’s true that it holds just over 8 oz. or 280 ml of water, but this is fairly standard for this type of product. On the flipside, it does come with an industry-best lifetime warranty. 

If you want to infuse your water with the most hydrogen possible and access your hydrogen water while you’re on the go or at the gym, then get the Piurify Hydrogenator Bottle.

Best Premium: Tyent H2 Hybrid (8.7/10)

  • Infuses water with up to 1,800 ppb of molecular hydrogen
  • Dual-stage filtration removes most city water contaminants.
  • Produces alkaline water in addition to hydrogen water.
  • Connects to your water supply line to provide endless hydrogen water.
  • Industry-best lifetime warranty
  • Significantly more expensive than other options

The Tyent H2 Hybrid is my #3 recommendation for hydrogen water machines and my top choice for a premium option because it produces hydrogen and alkaline water, filters most city water contaminants, and comes with a lifetime warranty. But it costs a small fortune.


The Tyent H2 Hybrid earned the #3 spot on my ranking for the following five reasons: 

Pro 1/5: Infuses water with up to 1,800 ppb

The Tyent H2 Hybrid ranked so high on my list and is my choice for the best premium hydrogen water machine because it lives up to its claim and is able to infuse water with up to 1,800 ppb of hydrogen

It does this using polymer exchange membrane (PEM) electrolysis and titanium and platinum plates. It’s true this is not as much hydrogen as smaller hydrogen water bottles are able to infuse, but it is still more than enough to allow you to take advantage of the potential positive health impacts of hydrogen water. 

This means that if you want a hydrogen water machine capable of delivering antioxidant rich hydrogen water with anti-inflammatory properties, you should get the Tyent H2 Hybrid

Pro 2/5: Dual-stage filtration removes most city water contaminants

The second positive aspect of the Tyent H2 Hybrid is that it is also a filter and removes a wide range of city water contaminants

It does this using dual-stage filtration. The first stage is a .01-micron-rated sediment filter that removes sand, dirt, dust, clay, etc. from your water. The second stage is activated carbon, which will filter chlorine, chloramine, VOCs, PFAs, herbicides, pesticides, and many other city water contaminants. This is a better filter than the one included in the Piurify Hydrogen Water Machine that’s ranked #1 on this list because that filter only removes chlorine and chloramine but is not effective against these other contaminants. 

This means that if you want a hydrogen water machine that can double as a filter and remove the vast majority of the contaminants in your city water, you should get the Tyent H2 Hybrid.

Pro 3/5: Produces alkaline and hydrogen water

The third pro of the Tyent H2 Hybrid is that it also is a water ionizer, aka an alkaline water machine

In addition to infusing your water with hydrogen, the Tyent H2 Hybrid can also adjust the pH of your water. It does this also using electrolysis, but this part of the water treatment process takes place in another chamber from the PEM electrolysis that produces the hydrogen gas. This is how the Tyent H2 is able to produce both hydrogen and alkaline water. While scientific evidence is still somewhat lacking, there are some initial studies that suggest it can help fight disease by neutralizing the acid in your bloodstream. 

If you want to experience the potential benefits of both hydrogen and alkaline water, you should get the Tyent H2 Hybrid because it can do both.

Pro 4/5: Provides endless hydrogen and alkaline water

The fourth noteworthy upside of the Tyent H2 Hybrid is that it provides you with endless hydrogen and alkaline water, unlike the majority of its competitors, which all treat a limited amount of water, from 8–32 oz, at once. 

It does this by connecting directly to your water supply line. After you choose your settings, indicating your desired pH and hydrogen levels, all you have to do is turn on the machine’s dedicated faucet and the water that comes out is infused with hydrogen and adjusted to the exact pH level you want. 

This means if you don’t want to bother with refilling a pitcher or bottle, or you don’t want to be limited by the size of your machine, you should get the Tyent H2 Hybrid.

Pro 5/5: Lifetime warranty

The Tyent H2 Hybrid does a lot of things, and it does a lot of things well. But it’s also very expensive. If you do decide to go with this hydrogen machine, I can see why, but the worst possible scenario is that you shell out several thousand dollars on a machine like this and then it breaks on you in a few years. Fortunately, this won’t happen, and Tyent has you covered if it does.

That’s why, for me, Tyent’s lifetime warranty is one of the biggest selling points of the H2 and why it’s on this list. No other premium machine I looked at came close to offering this kind of commitment to the product. The closest thing I found was a six-year warranty. I also like that this warranty covers everything, including parts, labor, and shipping. This way, if by some fluke something does break, you can go back to Tyent and they will take care of the issue with absolutely no cost to you. This is the type of service I would expect from anyone selling this type of machine, but Tyent is the only one that actually provides it. 

All of this means that if you want a premium hydrogen machine that is effective but also comes with the full support and warranty of the company that made it, you should get the Tyent H2 Hybrid.


The Tyent H2 Hybrid has one notable downside: 

Con 1/1: It costs a small fortune

The most obvious con of the Tyent H2 Hybrid is its price tag. 

While the price varies depending on the time of year and what promotion Tyent is running, you can expect to pay anywhere from $3,000–$5,000 for this unit. That is a ton of money for a hydrogen water machine, even if it does do a lot more than just infuse your water with hydrogen.
This is why it did not rank higher on the list. For most people, a more affordable option, such as the Piurify Hydrogen water machine, will be more than enough at just a fraction of what the H2 costs. 

If you want these extra features and aren’t scared by the price tag, this is a high-quality product that will help you take control of your water. But if you are looking for something with a more accessible price point, I would look at the Piurify options that are ranked #1 and #2 on my list.

Also, if you’re interested in alkaline water but don’t need to spend the money on a hybrid alkaline and hydrogen machine, check out some of my other reviews on alkaline filters: 

OVERALL: 8.7/10

All in all, the Tyent H2 Hybrid is an excellent hydrogen water machine and my top recommendation for a premium machine because it infuses up to 1,800 ppb of hydrogen into your water and is also an alkaline water machine that lets you choose the exact pH level of the water you drink. 

Yes, it’s considerably more expensive than any other product on the market, but it does come with a lifetime warranty that completely covers you in case something does go wrong. 
If you want a hydrogen water machine that will give you access to the potential health benefits of both hydrogen and alkaline water and don’t mind paying for it, then get the Tyent H2 Hybrid.

Honorable Mentions

Two perfectly suitable hydrogen water machines on our list may not match a consumer looking for a specific use or type of machine, but they’re still worthy of mention.

AlkaViva Vesta H2 Water Ionizer (8.3/10)

The AlkaViva H2 Vesta is well suited for people looking for an advanced water ionizer that provides clean alkaline, and hydrogen-rich water. 

With its nine-plate design and next-generation SMPS power supply, the Vesta ensures efficient water filtration and hydrogen infusion.

It boasts a range of features, including a DARC II Cleaning System for automatic cleaning after every use, a real-time flow rate control system for optimal water flow, and an auto-adjust power feature for efficient performance. 

The system’s pH range of 2.1–12 provides users with various alkalinity options to suit their preferences. The hydrogen infusion process involves a nine-plate design, ensuring maximum H2 performance of up to 1,600 ppb.

The AlkaViva H2 Vesta comes with a limited lifetime warranty and a 60-day return policy. However, returns require prior authorization from the manufacturer and a valid return merchandise authorization (RMA) number. 

Return shipping charges are the responsibility of the customer, who will incur a 25% restocking fee for all returned items. I recommend being sure you want it — that’s more than $1,000.

This system offers almost the same level of performance as the Tyent H2 Hybrid. The only difference is the Tyent’s more advanced features, which justify its premium cost. 

While it didn’t secure a spot among the top choices, mainly due to its premium cost and strict return policy, the AlkaViva H2 Vesta remains a great option for those seeking a high-quality hydrogen water machine in terms of performance. 

Buder HS-72 Hydrogen Water Machine (8.2/10)

The Buder HS-72 Hydrogen Water Machine is a countertop hydrogen water generator that produces hydrogen-rich water using DuPont’s SPE-PEM membrane technology.

It is primarily a design and creation of Victory (the manufacturer) in Japan, and the internal filters are made in the Buder factory in Taiwan, where the product is assembled, boxed, stored, and made ready for international sales. 

The hydrogen pumping membrane (inside the left chamber) is made by DuPont in the US, a company well known for its innovative products.

The machine’s PEM technology enriches the water with pure molecular hydrogen, reaching concentrations of up to 1,200 ppb. This technology provides users with hydrogen-rich water without residual chlorine or ozone.

The inclusion of an in-tank ion resin filter is a noteworthy feature. This filter, designed to reduce scale buildup on the electrodes, not only contributes to the low maintenance and longevity of the device but also ensures the hydrogen water is of high quality.

However, unlike the previous units we’ve looked at that have built-in filters, the Buder HS-72’s ion-filter only helps to reduce scale buildup in the system. It is in no way a substitute for an actual filter. 

Therefore, the manufacturer recommends using reverse osmosis (RO) or distilled water for the hydrogen infusion process. 

The system is significantly more expensive than the Piurify hydrogen generator we looked at previously, despite having less maximum hydrogen content and an inferior warranty coverage. 

Also, the warranty coverage may vary depending on the seller or distributor. I recommend checking with the seller or manufacturer for specific warranty details. 

For best results, purchase your unit from Alkaline Water Plus for its lifetime labor warranty and one-year parts warranty.

The Bottom Line: The Best Hydrogen Water Machine

Of all the hydrogen water machines I reviewed and tested, the Piurify Hydrogen Water Machine is my #1 recommendation thanks to its ability to infuse up to 1,300 ppb of hydrogen into your water, its large pitcher size, and its lifetime warranty. 

The Piurify Hydrogenator Bottle is the best portable hydrogen machine and is a great option for high-intensity athletes, and the Tyent H2 Hybrid is a premium hydrogen/alkaline water combo that is considerably more expensive but offers some great features. 

There are lots of hydrogen water machines out there, but only those on this list, and those that scored well in our rigorous testing process are really worth the money and will deliver the results you want.

Research Methodology: How We Test and Review Products

Reviewing water treatment products isn’t the most straightforward process, especially when you have to deal with the countless options on the market. 

That’s why we developed a seven-point review methodology to help us separate the wheat from the chaff and recommend the best options you can buy with your hard-earned money.

Please feel free to read about how we review water filters. In the meantime, here’s a brief description of how we do it:

Use analysis

The first step in the review process is to figure out what each hydrogen water machine is good at. 

For instance, you have systems like the Tyent H2 Hybrid, which offers an all-in-one solution, and the Piurify system, which offers all you need at an affordable price. This initial step helps us identify the key selling points in the dozens of systems available for review.

Read more about how we conduct our use analysis.

Tech check

Most manufacturers like to use a lot of buzzwords when describing the technologies incorporated into their systems. That’s why, for our second step, we cut through the jargon and investigate what’s going on under the fancy screens, buttons, and dials. 

We look into the real-world applications of these technologies and how they benefit the user.

Learn more about the tech check part of our review process.

Water test data

One way to know for sure if a water treatment system is best suited for the job is through third-party testing. 

Most top brands send their products to organizations such as the Water Quality Association (WQA) and the National Sanitation Foundation (NSF) for rigorous testing and eventual certification. 

We try as much as possible to collect this testing data from the manufacturers so we can verify it on our own. But, of course, not all manufacturers adhere to these practices. 

In such cases, we run our own tests.

To learn more about how we collect water test data, click here.

Installation test

Some of the most harrowing stories we’ve heard from our readers involve the improper installation of water treatment systems. 

These usually end with a visit from a very expensive plumber (who’s more than happy to cash in on their woes) or a broken part that needs replacement. 

To save you from these situations, we conduct our own installation and safety checks to make sure we only recommend products from companies that make the process easy.

Learn more about how we conduct our installation tests.

Cost-of-ownership analysis

As part of our comprehensive review process, we look into what it will cost to own a particular water treatment system. 

As you’ve probably noticed, these things don’t come cheap. But that doesn’t mean it should cost an arm and a leg to keep them running at home. 

That’s why we do our best to make sure we only recommend cost-effective products that provide more value for your money.

Read more on how we run our cost-of-ownership analysis.

Warranty check

Beyond the cost of ownership, we also need to make sure manufacturers are willing to provide support when things go wrong. 

This involves digging into their warranty and refund policies and going through every clause just to make sure you, the customer, understand what is covered and what is not. 

Click here to find out more about how we do warranty checks.

Customer service test

Lastly, we acknowledge that investing hundreds or thousands of dollars in a water treatment system is a huge commitment, not to mention the cost of running the system. 

Thus, we need to make sure the manufacturer is always willing to lend a helping hand when you run into problems. This is why we test the company’s customer service to see how good it is and what customers can expect from their service reps.

Learn more about how we do this here.

Before You Buy a Hydrogen Water Machine: How Effective Are They?

The popularity of hydrogen water machines can be traced back to the early 1900s, when water ionizers were first introduced. In 1965, the Japanese Ministry of Health, Labor, and Welfare acknowledged the alkaline water machine as a legitimate medical device for improving human health. 

This led to an increase in the manufacturing of water ionizers. 

Subsequently, in the 1970s, the Japanese-produced water ionizer was introduced to Korea, where machines were manufactured for individual household use. 

These water ionizers are still approved as medical devices by the South Korean government for use in clinics and hospitals today.

Over time, advancements in technology, such as the use of SPE-PEM membrane technology, have contributed to the development of high-quality hydrogen water machines that offer safe and healthy ways to access high levels of molecular hydrogen.

How Does a Hydrogen Water Machine Work?

Here’s a basic explanation of how a hydrogen water machine usually functions:

  • Electrolysis: The machine contains an electrolysis chamber where water is split into hydrogen and oxygen gases using an electric current. The hydrogen gas produced is then dissolved into the water.
  • Dissolution: The generated hydrogen gas dissolves into the water, creating hydrogen-rich water.
  • Dispensing: Users can then drink the hydrogen-rich water produced by the machine.

A couple of buzzwords that get thrown around are solid polymer electrolyte (SPE) and proton exchange membrane (PEM).

In traditional electrolysis, water is split into hydrogen and oxygen using a liquid electrolyte. 

SPE and PEM technologies, though, use a solid polymer electrolyte or a proton exchange membrane as the electrolyte. This membrane selectively allows protons to pass through while blocking the passage of gases like oxygen. 

This ensures that only hydrogen gas is collected on one side of the membrane. The hydrogen gas produced during the electrolysis process is collected and then dissolved into water to create hydrogen-rich water.

Benefits of Drinking Hydrogen Infused Water

Research on the potential health benefits of drinking hydrogen-rich water is still in its early stages, and while some promising findings exist, more robust and extensive studies are needed

Here are some of the suggested health benefits associated with consuming hydrogen-rich water, based on available research:

  • Antioxidant properties: Molecular hydrogen is believed to have antioxidant properties, meaning it may neutralize harmful free radicals in the body. This results in a reduction of oxidative stress, which is associated with aging.
  • Anti-inflammatory effects: Drinking hydrogen water may help alleviate inflammation-related conditions, though more research is needed to establish the extent of these effects.
  • Improved athletic performance: Some studies suggest that hydrogen-rich water may improve exercise performance, reduce exercise-induced fatigue, and encourage faster recovery. 
  • Neuroprotective effects: Drinking hydrogen infused water reportedly protects against neurological disorders and supports cognitive function, but further research is required.
  • Cardiovascular health: Hydrogen has been explored for its potential support of cardiovascular health, including improved blood vessel function and potential blood pressure regulation.

It’s crucial to note that while these potential benefits are based on preliminary research, not all studies have produced consistent results. Additionally, individual responses to hydrogen-rich water may vary. 

Before incorporating hydrogen-rich water into your routine, consult with health-care professionals, especially if you have existing health conditions or take medication. While hydrogen-rich water is generally considered safe, its long-term effects and optimal usage require further investigation.

Frequently Asked Questions

How does a hydrogen water machine work?

Hydrogen water machines use advanced electrolysis technologies, such as a proton exchange membrane (PEM) or solid polymer electrolyte (SPE), to generate and dissolve molecular hydrogen into water. 

This process creates hydrogen-infused water with potential antioxidant and anti-inflammatory properties.

Are hydrogen water generators worth it?

The addition of hydrogen gas to water improves its anti-inflammatory and antioxidant effects. It has been praised for its potential to boost energy, decrease the aging process, and promote muscle recovery after exercise.

Hydrogen water generators can be worthwhile if you need antioxidant-rich water with these potential health benefits. Factors like ease of use, hydrogen concentration, and personal health goals can help influence your purchase decision.

However, their effectiveness isn’t scientifically proven, so it’s important to consult with your doctor before taking any nutritional supplements.

Which water is best for hydrogen production?

Distilled water is best for hydrogen production in these machines. 

While they can use tap water, the hydrogen generator chamber must only be filled with distilled water or deionized water, free of minerals, which ensures optimal hydrogen production.

It’s also a good idea to use filtered tap water for the pitcher chamber. Tap water with certain impurities can damage the machine.

Do hydrogen water bottles really work?

Yes, hydrogen water bottles can work. They use advanced technology, such as SPE/PEM technology, to ensure the hydrogen concentration in the water is consistent and effective. 

While research on benefits is ongoing, many users report positive experiences with improved hydration and energy.

Can you drink too much hydrogen water?

While hydrogen water is generally safe, it’s important to consume it in moderation. 

Like any dietary supplement, excessive consumption may lead to unintended effects. Follow the usage guidelines provided with the specific hydrogen water machine or product. 

Taking too much water, hydrogenated or otherwise, can cause hyponatremia. This is where the level of sodium in the body is low due to too much water content. 

Plus, it’s unclear how much hydrogen water you need to drink to reap its potential benefits.
