HYDROGENYX's commitment
One promise:
action, not logos.
HYDROGENYX was born out of an obsession: a molecular hydrogen water bottle whose concentration is actually verifiable. Not a leaflet. Not an argument. A measurement.
Manufacturing is entrusted to an industrial partner specializing in SPE/PEM electrolysis, selected after comparing manufacturers.
The concentration is checked with the DPD reagent, the reference colorimetric method: a few drops, the water changes color, the level is read.
The electrolysis cell is guaranteed for 5 years: if it weakens, we replace it, no questions asked. And you have 60 days to change your mind — satisfaction guaranteed or your money back.
Three commitments
What sets us apart

Founder's Note
"You don't have to take our word for it: you can measure the concentration yourself with the DPD reagent."
