HRW – Hydrogen Rich Water


Heinrich H.: The U.S. researcher Tyler LeBaron writes that the content of dissolved hydrogen is the sole therapeutic advantage of activated water, even if “mildly alkaline water” from a water ionizer from the same drinking area as you, say between pH 8 and 9, is certainly recommended. If I am not too acidified, because I move a lot and am healthy and eat alkaline foods, why should I then buy a relatively expensive water ionizer and not one of the new electric Hydrogen Rich Water Makers, which are much cheaper and specifically geared to replenish the water with hydrogen gas?


Your question is understandable. But it is, first of all, not a question of price. Because good electric HRW Makers are nothing more than batch ionizers that, usually much smaller versions for small quantities, are much cheaper than the trendy HRW devices. If you must drink the water necessarily in the neutral pH range, because you don’t want it alkaline, then just remove from a cheap batch ionizer the diaphragm and you then also produce the same HRW. Because batch ionizers work usually even faster with more power.

After 2007, since the state of research on the therapeutic benefits of HRW exploded, I would not contradict you and Prof. Le Baron, that HRW obtained by electrolysis without a diaphragm can be usefully applied and secured in many therapies.

The first effect complies with the 1937 medicinal product marketed by the German engineer Alfons Natterer. Hydropuryl N, which he created in the middle chamber of a 3-chamber cell without a diaphragm membrane.

Only in the 60’s was this neutral electrolytic water of the varieties Hydropuryl S (sour/acidic) and Hydopuryl A (alkaline = basic) pushed back. For the same effect can be achieved by back-mixing A and S. Therefore, for decades no 3-chamber cells are needed, and the 2-chamber system has prevailed.

You can create with each flow through water ionizer HRW, by bringing together the alkaline and the acidic outlet during filling. The yield of hydrogen and oxygen is much greater, because the electrolysis cells are trimmed to high performance. Such devices are of course more expensive, but also offer the advantage of a built-in pre-filter, which is recommended often for our tap water, especially if we want to ionize it for drinking.

An HRW Maker is a one-cell electrolysis device. The water is thus not only enriched with hydrogen from the cathode, but also with oxygen from the anode. With hydrogen we have a desired effect with therapists because of its antioxidant character. Oxygen on the other hand, is the opponent of hydrogen and thus oxidative, but the oxidation of hydrogen (2H2O) is not immediate, and happens with detours, so that both gases remain reasonably stable and separated in the water and do not react to water.

Still, after 14 hours even with multiple HRW production is everything over, as you can see in my readings below in a HRW device called SUSOSU Plus (Identical to Arui Hendy) with Munich tap water.


By pressing the button 1 time, a 3-minute electrolysis process occurs in which one sees both oxygen and hydrogen bubbles rising. In addition to pH and ORP I have the TDS value, the conductive particles measured in ppm. This device also has a small ring filled with minerals, the use of which worsened the result. It is intended mainly for very soft water, as it prevails in Japan and Korea, so in these parts of the world does not count for much.

So what could now be said of such a product? Oxygen has a slight flavour enhancing effect. Everyone who has tried swirled or levitated water knows this because a water vortex is nothing more than an ORW-Maker (Oxygen Rich Water) by swirling oxygen from the air. But swirlers usually have no powerful prefilter and if at all, they are mounted before the swirler, which really is not recommended with our polluted and often germ-laden air. Therefore, an HRW Maker, which is filled with filtered water, is definitely preferable, in my opinion, to a swirler. Incidentally, they also increase the ORP by catapulting hydrogen and carbon dioxide and simultaneously mixing in oxygen. With the loss of carbon dioxide the water does become slightly alkaline. This also happens in a HRW device, because here during electrolysis carbon dioxide is expelled. Also activated water that is mixed back from a batch or flow through ionizer is usually slightly more alkaline than the tap water.

By pressing 8 times, i.e. 24 minutes production time you get 779 micrograms. This value no longer increases with 60 Minutes Production time (20 x 3 min) or 75 minutes (25 x 3 min). The maximum point in the water used settles at 828 micrograms / l. This is slightly more than half of the highest amount with this kind of water with a diaphragm – ionizer measured by myself with a maximum value of 1577 micrograms / liter . So you need to drink about twice the amount of water in order to benefit from the same amount of hydrogen as with this Susosu HRW device . That’s basically not bad, because you are supposed to drink a lot of activated water, instead of the usual strong oxygen and carbon dioxide-rich everyday drinks. But who likes to drink water constantly! I therefore think the alkaline water from a diaphragm – ionizer is significantly better than the water from a HRW device.

What is the reason for that? The explanation is, in my view, from the counter effect of oxygen and hydrogen in a non-diaphragm electrolysis separated redox process between the simultaneously produced hydrogen and oxygen. This has not yet been fully explained for electro activated water. Nevertheless, the basis of an explanation is simple and over 200 years old, in the research guessed already by the founders of electrochemistry Alessandro Volta and Johann Wilhelm Ritter and the ingenious discoverer of electrical activation of water; Alfons Natterer. The great chemist Nernst, with his seemingly all-explaining pH / redox potential equation had only viewed the substances dissolved in water, but not the water itself that gets new properties through the process of diaphragm electrolysis. Only Vitold Bakhir in the 1970’s had perceived this, but was not able to explain it.

Water molecules are known to consist of two hydrogen atoms and one oxygen atom. These are in a mutual redox equilibrium, which can be expressed in millivolts and is in a specific dependence of the pH value.

If now, the same as with water electrolysis without a diaphragm, oxygen and hydrogen gases out of the water, the redox equilibrium changes, depending on which gas leaves the water faster. This in turn entirely depends on the complete composition of the tap water, how much of these two and other gases were already dissolved in the water prior to electrolysis.

Described on the penultimate page are the SUSOSU measurement examples which show that a 3 minute electrolysis showed the lowest redox potential. It has thus achieved at this stage more dissolved hydrogen in water than oxygen. This ratio then changed at the 7 x 3 = 21 minute long electrolysis, because the redox potential rose again. After 14 hours the water was back, approximately equally balanced between oxygen and hydrogen, like before electrolysis.
In diaphragm electrolysis, oxygen is removed from the cathode water, whilst it accumulates only in the anode water. The hydrogen in the cathode water, however, has no redox partner and the water gets a very low redox potential.

So when it comes to actually producing hydrogen rich water, diaphragm electrolysis is fundamentally superior. Abundance of hydrogen is like someone going shopping with a lot of money: You do not know if the buyer pays for everything with a credit card or whether that person really is so rich. The fact is that you can also buy sensible things on credit.


In this sense, the hydrogen produced in a HRW Maker by single electrolysis makes sense, just as more than 500 serious studies with such water show. You can find clear and up to date information on the website:

Of course, no one will want to give up, if like me you have been drinking alkaline activated water for 11 years at pH 9.5, the alkaline part of activated water from diaphragm electrolysis.

As soon as with ca. 45 years, for unknown reasons, the alkaline buffer of bicarbonate in human blood tilts, I stand by Dr. Walter Irlacher: With age and lifestyle come the spa and hyperacidity diseases. His concept of de-acidification we have presented together in the Service Manual for Humans since 2006 scientifically and hitherto have been unchallenged by tens of thousands of readers and patients. I am still completely convinced: oxygen does not belong in the water, but in the lungs and into the blood.

And a maximum of saturated hydrogen-rich water possible should pass through your digestive system. That’s why we should drink it.

What is the role of hydrogen in our body? It is just the basic currency of all energy processes in the body. In his Nobel Prize acceptance speech in 1937, Albert Szent-Györgyi expressed it like this: “Our body really knows only one fuel, hydrogen. Our food, carbohydrates, is basically only a hydrogen package … and the main event during its combustion is the elimination of hydrogen.” Simple and no better way to express it. Chemically, it is very complex.

Back to your question: I admit that what I eat is not always healthy and I am doing too little exercise. For this I argue with the usual acidity diseases such as diabetes, allergies and cancer for supremacy in my body.

But for all-round healthy people, who are actually not too acidic, I see in HRW water already as an alternative to get away from the really overacidified drinks and waters.

Because even switching from soda to plain tap water reduces the acid load in the body more than any change of a diversified diet to vegetarian. This is even more the case when you change to very slightly alkaline HRW, if you do not need to jump to the right alkaline activated water.

Although it is only half the effect in the alkaline area. Anyway, better than the cascade of acidosis syndromes to acidification disasters – like the uninformed others – to slide further into an age of suffering and disease. I myself was on this path, until I started to think more thoroughly.
