Why use a hydrogen water generator?

Hydrogen water is ordinary drinking water enriched with molecular hydrogen (H2), which is being studied in the scientific literature as a selective antioxidant. Daily hydration plays an important role in how the body functions, and more and more people are looking for a simple way to enrich it without chemical supplements or complicated dosing.

The H2O nanotec hydrogen water generator turns ordinary tap or bottled water into hydrogen water in 3 minutes, with a high H2 concentration and a negative oxidation-reduction potential (ORP). The result is a clean drink with no added taste, colour or odour that you can drink straight after the cycle.

The hydrogen water generator is suitable for households and individuals who want to drink water enriched with molecular hydrogen regularly, have hydrogen water at hand during sport and the working day, and want a portable solution with no filters, tablets or refills to buy.

How does the H2O nanotec hydrogen water generator work?

Once the bottle is filled with drinking water and the cycle started, the water undergoes electrolysis, which releases pure hydrogen gas from the water molecules. The whole process is automatic and controlled by built-in electronics in the base of the device.

Hydrogen water is generated in three steps:

1. Fill the bottle – pour drinking water up to 80 °C into the glass body and attach the base with the electrodes.

2. SPE membrane electrolysis – a food-grade solid polymer electrolyte (SPE) membrane separates hydrogen from oxygen and releases molecular hydrogen directly into the water without unwanted by-products.

3. Automatic end of cycle – after 3 minutes the generator beeps three times and switches off automatically.

After the cycle the water is ready to drink straight away. The generator needs no chemical tablets, filter cartridges or other consumables – it works only with drinking water and electricity from the built-in battery.

What does hydrogen water from the H2O nanotec generator offer?

The H2O nanotec hydrogen water generator is designed to reach a high molecular hydrogen concentration in a short cycle. The combination of SPE electrolysis and a high-quality glass body helps to ensure:

  • a high molecular hydrogen concentration of 1100–1680 PPB,
  • a negative oxidation-reduction potential (ORP) of -300 to -750 mV,
  • clean hydrogen water with no added taste, colour or odour,
  • fast preparation in a single 3-minute cycle,
  • repeatable generation with no consumables to buy.

Note: The hydrogen water generator is not a medical device and is not intended for the diagnosis, treatment or prevention of any disease. The effects of hydrogen water on the human body are the subject of ongoing scientific research and may vary between individuals. If you are pregnant, breastfeeding or have health problems, we recommend consulting a doctor before use.

Who is the hydrogen water generator for?

The H2O nanotec hydrogen bottle is for anyone who wants to enrich drinking water with molecular hydrogen quickly and easily and make it part of their daily hydration.

It is especially appreciated by:

  • athletes and active people,
  • people working under pressure and stress,
  • followers of a healthy lifestyle,
  • users who want to regularly drink clean water enriched with molecular hydrogen without chemical supplements,
  • travellers and people on the go, thanks to its compact portable size,
  • anyone looking for a simple way to make hydrogen water without tablets or filters.

The generator is not a medical device and is not intended to treat health problems. It does, however, make it quick and easy to prepare water enriched with molecular hydrogen as part of a regular drinking routine.

Why SPE membrane electrolysis instead of hydrogen tablets?

Hydrogen water is usually prepared in two ways – by dissolving hydrogen tablets in water or by electrolysis using a generator. Tablets release hydrogen through a chemical reaction, which means repeated purchases and precise dosing, and the resulting concentration and dissolution speed may vary.

The H2O nanotec generator uses electrolysis with a food-grade solid polymer electrolyte (SPE) membrane. Hydrogen is released directly into the water during a controlled 3-minute cycle, without adding chemicals and without waste from single-use tablets.

SPE electrolytic generator vs. hydrogen tablets

H2O nanotec generator Hydrogen tablets
Hydrogen generation method SPE membrane electrolysis chemical reaction of a tablet
Consumables to buy no yes, repeatedly
Preparation time 3 minutes several minutes, depending on dissolution
Substances added to water none tablet residue
Repeated use yes, unlimited one use = one tablet

 

Using and charging the hydrogen water generator

The H2O nanotec generator is easy to operate – the whole family can use it without complicated settings.

How to make hydrogen water:

  1. Fill the glass bottle with drinking water up to 80 °C.
  2. Put the base with the electrodes and the lid back on the bottle.
  3. Press the button once to start generation.
  4. Wait 3 minutes until the device beeps three times and switches off automatically.
  5. The hydrogen water is ready to drink straight away.
  6. Charge the generator with the USB-C cable; a full charge takes about 3.5 hours.

The integrated 1000 mAh lithium battery and power consumption under 5 W let you charge the generator with a standard mobile phone charger with a USB-C connector, at home or on the go.

Do water quality or temperature affect the result?

The generator is designed exclusively for water meeting EU drinking water hygiene standards; the maximum water temperature is 80 °C. Never pour fruit juices, sweetened drinks, tea, coffee or other chemical solutions into the bottle, as they could damage the electrodes and the SPE membrane.

Before first use, activate the SPE membrane by running a cycle with warm water (up to 80 °C) so that the generator reaches the stated hydrogen concentration. The resulting H2 concentration and ORP value may vary slightly within the stated range depending on the quality and temperature of the inlet water.

How to care for the generator and extend its life

Regular and correct care of the hydrogen water generator helps maintain its function and the stated hydrogen concentration throughout its life.

  • always leave a small amount of water in the bottom of the bottle so the SPE membrane does not dry out,
  • protect the base with the electronics from running water, especially the charging connector and the button,
  • with hard water, clean the electrodes with a citric acid solution or white vinegar,
  • never clean the electrodes with sharp objects,
  • do not let children use the generator unsupervised.

Regular care of the membrane and electrodes is important to maintain the stated hydrogen concentration and hygienic operation.

Clean hydration for an everyday and active lifestyle

The H2O nanotec generator lets you make hydrogen water anytime, anywhere – at the office, after training or on the go. Thanks to its compact size and USB-C charging, it easily becomes part of your daily drinking routine.

The generator works without adding chemical tablets or dosed preparations to the water. It needs no attention apart from regular charging and basic care of the membrane and electrodes.

FAQ

Everything you need to know about the H2O nanotec hydrogen water generator

🔬 How generation works: The SPE membrane separates molecular hydrogen from oxygen by electrolysis and releases it directly into the water. The resulting hydrogen water reaches a concentration of 1100–1680 PPB and a negative ORP of -300 to -750 mV. Actual values always depend on the quality and temperature of the inlet water and the condition of the SPE membrane.
