The portable generator that brings together essential technical criteria in an everyday format, without compromising on quality.
The hydrogen water generator market is saturated with products that promise a lot and deliver little. Advertised concentrations without certification. Devices without a drain valve that mix H₂ and oxidizing by-products in your glass. Uncertified materials. Brands with no after-sales service in France.
The Vattenyx generator was designed to be the opposite of this logic: a single device, with the right technical criteria, at the right price.
This is the criterion that separates a true hydrogen water generator from a low-end electrolyzer. The SPE/PEM (Solid Polymer Electrolyte / Proton Exchange Membrane) integrated into the Vattenyx generator works with a hermetically separated dual chamber:
Beverage side: pure H₂ is produced and dissolved directly into your water. Nothing else.
Drainage side: oxygen, chlorine, and ozone generated by electrolysis are evacuated separately via the drain valve—without ever coming into contact with your drinking water.
Result: water enriched with pure molecular hydrogen, without oxidizing by-products that would cancel out the desired antioxidant effects. It is precisely under these conditions that clinical studies on H₂ have been conducted. (Molecular Hydrogen Institute)
The Vattenyx generator's electrodes are made of platinum-coated titanium, the reference standard in technical literature on water electrolysis. Titanium is chemically inert in water: it does not corrode, does not release any metallic ions into your drink, and maintains its performance over time. Estimated lifespan: 3 to 5 years with normal maintenance.
No more proprietary cables that can't be found six months after purchase. The USB-C connection of the Vattenyx generator can be recharged from any phone charger, laptop, or external battery. This is a detail that makes a difference in everyday life—and a sign that the product was designed for real use, not just attractive packaging.
5-minute cycle for daily hydration and basic antioxidant support. Ideal in the morning, at the office, between meetings.
10-minute cycle for enhanced concentration, recommended before and after physical exertion, or for individuals seeking a more sustained anti-inflammatory effect in accordance with sports study protocols. (Aoki et al., 2012, Medical Gas Research)
It is not an alkaline ionizer disguised as a hydrogen water generator. It does not significantly alter the pH of your water, which is precisely an advantage for your body's natural acid-base balance.
It makes no medical promises. It produces hydrogen water at a biologically significant concentration, under technical conditions validated by research. What your body does with it depends on your individual biological terrain.
The regular athlete looking to optimize recovery between sessions without burdening their supplementation routine. The Vattenyx generator fits in a gym bag, recharges on the go, and produces effectively concentrated water in 5 minutes before and after training.
The active and stressed person who wants practical daily antioxidant support, without logistical constraints. A bottle, a button, fresh hydrogenated water in less than 10 minutes at home, in the office, or while traveling.
Anyone starting out who wants to seriously test hydrogen water, with a device that respects the basic technical criteria—without spending €300 on a high-end model before establishing their own experience.
The family transitioning to daily use in addition to an existing filtration system (reverse osmosis, ceramic filter) for water that is both purified and enriched with H₂.
Use filtered or low-mineral water as input. The Vattenyx generator enriches water; it does not filter it. Filtered water upstream (reverse osmosis, activated carbon filter) yields the best concentrations and preserves the membrane over time. Highly mineralized waters (Contrex, Hépar) quickly saturate the membrane and reduce performance. Low-mineralized waters (Volvic, Evian, reverse osmosis water) are ideal.
Consume within 30 minutes of production. The half-life of dissolved H₂ in an open container is approximately 120 minutes. To benefit from maximum concentration, drink chilled, with the container closed until consumption.
Maintain regularity for at least 4 weeks. The effects documented in clinical studies are not immediate; they are part of a progressive biological process. Users who report noticeable changes are those who have maintained daily consumption over time. (Dhillon et al., 2024)
Clean the electrolysis chamber regularly. Rinsing with clear water after each use and a thorough cleaning cycle every 2 to 3 weeks maintain performance and extend the membrane's lifespan.
To put the Vattenyx generator in its market context: portable SPE/PEM devices with titanium-platinum electrodes, integrated drain valve, and USB-C charging typically sell for between €120 and €300 depending on the brand and additional features (OLED screen, integrated inhaler, premium design).
The Vattenyx's pricing strategy is based on a deliberate choice: to concentrate investment on the components that determine the actual quality of the water produced, rather than on finishes or secondary features that increase the bill without improving the H₂ you drink.

Can it be used with tap water? Yes, but we recommend filtering it upstream (at least an activated carbon filter) to reduce chlorides and extend the membrane's lifespan. Unfiltered tap water loaded with limescale and chlorine generates more by-products to be evacuated and clogs the electrodes faster.
How many cycles per charge? The rechargeable lithium-ion battery via USB-C allows for a sufficient number of cycles for daily use without daily recharging, ideal for mobile use. Recharge from any available USB-C source.
Is the H₂ concentration measured? SPE/PEM technology guarantees the production of pure H₂. You can verify the presence of dissolved H₂ yourself with an H₂ Blue test (a colorimetric reagent developed by the Molecular Hydrogen Institute); a few drops in your glass after the cycle confirm the presence of active H₂ by a color change.
Is it compatible with all bottles? The Vattenyx generator is designed for standalone use with its integrated reservoir. Consult the complete product sheet for compatibility details.
Is there after-sales service in case of a problem? Yes. The Vattenyx store provides direct customer support—no intermediaries, no outsourced support. In case of a technical problem, an exchange or return can be arranged according to the current general terms and conditions of sale.
