Hydrogen Water Machines & Hydrogen Gas Generators

Hydrogen water machines and hydrogen gas generators are a new way to get very high levels of molecular hydrogen in our drinking water. If your body doesn't seem to need the alkalizing benefits of a water ionizer, simply pumping molecular hydrogen into your water and/or inhaling it may be the best choice for you. Hydrogen water machines and hydrogen gas generators offer the healing benefits of molecular hydrogen without changing the pH of the water. For more explanation about hydrogen water benefits, go to our 100-Studies page or watch this video.



Hydrogen water (pure molecular hydrogen pumped into water) and hydrogen gas have been shown to have a huge number of benefits to health. I encourage you to watch this fairly short video, which does a good job summarizing the many benefits of hydrogen water.


We have tested many different brands of hydrogen water machines and hydrogen gas generators before offering our selection, above. We do our best to bring you what we feel is the best to offer in each category of product.

Hydrogen water machines and hydrogen gas generators are a great way to consume antioxidant water which has not been ionized or split into 2 streams (alkaline/acidic) like a water ionizer does. 

The two most practical ways to get hydrogen water at home are hydrogen water machines and water ionizers. Hydrogen water machines are a bit different than water ionizers. Both machines produce molecular hydrogen, but here's a simple list of differences:

  • Hydrogen water generators don't split the water into 2 streams or give off waste water to any great degree.
  • Hydrogen water machines don't alkalize the water, or if they do, it's very little.
  • A hydrogen water machine is really an "antioxidant water machine". It pumps molecular hydrogen into the water only, without changing the pH. 
  • Hydrogen water machines and hydrogen gas generators do not have many settings to choose from, just one setting.
  • Our home hydrogen water machines and hydrogen gas generators are not meant for commercial use, and if they are used commercially their membranes will need replacement more frequently.
  • If you are primarily concerned about getting enough hydrogen infused water, and less concerned with the ability to alkalize your water, then the best match for you would be to purchase a hydrogen water generator.  


Hydrogen gas generators make it possible to simply inhale hydrogen for the pure hydrogen benefits, but can be also be used to create hydrogen water, by pumping hydrogen gas into any liquid with a hydrogen gas machine. The hydrogen water made by a hydrogen gas machine pumping hydrogen into the water for only a few minutes stores just as good as ionized water if you store it in vacuum sealed bottles.


Hydrogen water machines are not the same as water ionizers. All hydrogen water machines, once used are only returnable if they are in like-new condition (meaning that all packaging, instructions, and parts are there and there is no sign of usage). Provided the machine fits this definition of like-new, there is still a 20% re-stocking fee. If it doesn't fit this definition, we cannot take it back.

How Are Hydrogen Water Machines Different From Water Ionizers?

The biggest difference between hydrogen water machines and water ionizers is that they don't alkalize the water. In my case my body needs and likes alkalizing, so my favorite antioxidant water machine is an electric water ionizer, but I do like a variety though. Some people do better getting their molecular hydrogen antioxidants pumped into neutral water. I personally like to have both kinds of ionizing machines, water ionizer and hydrogen machine, so I can have variety. There are many times during the day when I will get my antioxidant water from one of my home hydrogen generators (simply for variety). I like the extra boost of molecular hydrogen that gets pumped into these machines.

Another big difference is that Water Ionizers are so much easier to use than a hydrogen water or hydrogen gas machine. With a water ionizer there is no wait-time. You just turn the knob and out comes the water. It's also usually really good filtration too.

Do-It-Yourself Hydrogen Water vs. Bottled Water

Our whole website focuses on do-it-yourself hydrogen water vs bottled water, because there is no other conceivable way to buy molecular hydrogen water than to make your own with either a hydrogen water machine or water ionizer.

You cannot buy this water at the store, period. Hydrogen is a very light gas and without storing it in a vacuum sealed bottle it has a half-life of about 2 hours. Once the hydrogen is pumped into your water after if it's left out in a glass, pitcher, or plastic bottle, in about 2 hours there will be half the amount of molecular hydrogen in that water. Two more hours later you can expect only one fourth of the original molecular hydrogen levels, and so on. After a day, you no longer have antioxidant water. We suggest that if you want the highest antioxidant water from your hydrogen water machine then you should either bring the hydrogen water machine with you to work or get some vacuum stainless bottles to store the water in. This way you can take water to work with you, that still has lots of molecular hydrogen in it when you drink it hours after pouring. 

Comparing Hydrogen Water Machines

  • HS-72 Hydrogen Water Generator: 
    • Can get up to 1.2 ppm of molecular hydrogen
    • Not particularly portable. Sits on counter
    • Uses whatever water you pour into the pitcher
    • Takes 10-20 minutes to pump hydrogen into the water (depending on if you fill it with 1 or 2 liters of water)
    • Uses SPE/PEM technology (doesn't add chlorine, ozone or nitrogen to water)
  • High-Rich Hydrogen Water Machine:
    • Can get up to 1.2 ppm of molecular hydrogen
    • Portable
    • Holds up to 10 ounces of water
    • Uses whatever water you pour into the cup
    • Takes 5-7 minutes to pump hydrogen into the water.
    • Alternately, can hook it directly to a bottle of your choice
    • Has rechargeable battery which can get up to 10 uses before needing to be recharged.
    • Uses SPE/PEM technology (actually removes chlorine, ozone and nitrogen from water)
  • Hydrogen Gas Machines can also bring the hydrogen content of any liquid up to about 1.2 ppm of hydrogen by placing the hose into water (or other liquid) for several minutes. For anyone who wants to pump hydrogen into juice, soup, or other liquids, a hydrogen gas machine is the only way to do it. Also, hydrogen gas machines are great for inhaling too.

Caution: Some Brands of Hydrogen Water Machines are Unhealthy

Some brands of Hydrogen water machines are dangerous (those where solid plate technology is used), because toxic ozone (a byproduct of hydrogen production) is released into the drinking water in these machines. All of the cheaper brands of hydrogen water machines and even most of the more expensive brands of hydrogen water machines use this type of solid membrane in their machine. Be very careful where you buy your hydrogen water machine from. The hydrogen water and hydrogen gas machines that we sell are the highest quality (DuPont made SPE/PEM membranes or MEA membranes from DuPont), which do not have any of these toxic byproducts. This video explains and demonstrates why you should always use SPE/PEM technology when producing hydrogen water from an electric hydrogen water generator.



Hydrogen gas machines pump out a controlled amount of H2-antioxidant-gas into the hose-line you attach to the machine. You can breathe H2 gas for up to a half-hour at a time. It's very therapeutic.


  • Use it breathe in H2 gas (antioxidants) while sitting or reclining.
  • Make any water hydrogen-rich.
  • Make other liquids, such as foot-soaks; body-wash solutions, juices or even soups into hydrogen-rich solutions.


  • I expect that inhaling/breathing hydrogen gas will benefit the eyes, ears, nose, facial skin, bronchi and lungs quite well, among many other organs.
  • One can also use the hydrogen gas generator to make molecular hydrogen enriched water by placing the hosing into a container of water for several minutes. The hydrogen water produced by h2 gas machines this way actually rivals just about any water ionizer or hydrogen water machine in the hydrogen concentration and stability of the hydrogen to stay in the solution long enough to consume.

I am happy to be able to use and offer h2 gas machines. Hydrogen gas generators are great to use at any time when you are relaxing or sitting still. They are scientifically designed to pump high levels of H2 anti-oxidants into a thin, plastic tube (called a cannula), which you would usually just breathe in while sitting or reclining.

  • The h2 gas machine should produce 150 or so liters per minute of hydrogen gas to be considered practical to use as a regular inhaler. Less than that is fine too, and will give therapeutic benefits. The faster the flow-rate, though, the less time it would take to get the same H2 breathing benefits of the longer time. (Example: If I am using a hydrogen gas machine with a 200 lpm flow-rate I would inhale for 30-minute periods, but if I was using a 300 liters per minute flow-rate hydrogen gas generator I would only inhale for 20 minutes to get the same benefit.
  • Keep in mind there is no reason to overdo hydrogen gas breathing. The body needs balance and while hydrogen gas inhaling is obviously wonderfully therapeutic, breathing it excessively isn't necessary. Exactly how much and how strong of a flow for H2 breathing is something each person needs to determine for themselves. Just observe what your body likes.
  • Look for a hydrogen gas generator which has a final stage drying filter that the gas goes through. This kind is my personal preference, because it feels better.
  • A feature I look for in the best hydrogen gas generators is a timing mechanism, which turns the machine off automatically after the selected time. If the machine doesn't have this feature, I would suggest to use an external timer.  


With hydrogen gas machines pretty much any liquid can be converted into a high-antioxidant drink. The possibilities are almost endless. Juices, hot drinks, and even soup can be transformed this way. No other equipment can do this.

Hydrogen gas generators are very versatile. A H2 gas generator is able to give you the the greatest amount of molecular hydrogen antioxidants of any other machine, however these generators are not for everyone, and here's why:

  • While hydrogen gas generators are emitting a controlled amount of hydrogen gas into the cannula tube, and they are quite safe when used as directed, one needs to use care to not operate it around open flames because it could cause sparks, especially if it's for excessively long periods and where there wasn't good enough ventilation.
  • One must use strict safety protocols around any equipment that generates gas, and don't leave it running too long. The suggested time-period for breathing at any one time is an hour or less. It's also suggested to leave a half hour of rest in between uses.
  • Hydrogen gas machines should be monitored by a responsible adult who has no mental impairments.

I am happy to be able to use and offer to others this type of molecular hydrogen machine. It is a different way to consume hydrogen antioxidants. I expect it will reach a slightly different set of body organs than drinking ionized water allows, such as: the eyes, ears, nose, facial skin, bronchi and lungs pretty intensely.

Here is video-testing I've done with this equipment. I put this comparison video on both of the product pages. Basically the SPE270 is a little stronger. The two machines are both very high quality and they both use DuPont's SPE-PEM hydrogen pump membranes. [Note: All of the hydrogen gas machines we sell at Alkaline Water Plus use DuPont's SPE-PEM hydrogen pump.


With hydrogen machines the membrane that produces the hydrogen can easily dry out if the machine is stored without using it for several months. Note: If you ever do allow this Hydrogen machine to dry out, simply follow the instructions to set it up and use it, but be aware that it may be a day or two before the membrane finally reaches its optimum levels.


All orders for the hydrogen machines from Alkaline Water Plus are pre-orders, and will be delivered approximately 3 weeks after the date of order. We do this to ensure you are always getting the latest upgrade of the machine, freshly made. We also don't want to take a chance that the membrane will dry out. Hydrogen gas machines work best when used regularly. If we stock them, even for just a few months, the SPE-PEM membrane dries out it takes a vinegar wash usually to get it moistened up again. For this reason it is far better to have hydrogen machines produced "on-demand". This process usually takes about 3 weeks.


Most of our hydrogen gas generators are only available for US shipping. Hydrogen gas machines are the most delicate of the equipment we sell, and so we don't want to risk the harsh treatment of international shipping.
