Hydrogen wellness, used correctly, is safe.

Molecular hydrogen (H₂) has been studied in over 1,000 peer-reviewed papers. It has no known toxicity at the concentrations used in published research. It is the smallest molecule in existence — it passes freely through cell membranes and is exhaled or dissolved naturally. No accumulation. No known adverse effects at the concentrations delivered by Hydrogen Wellness™ devices.

The question is not whether hydrogen is safe — the research is clear. The question is whether the device delivering it is safe. That is where certification matters.

Hydrogen Wellness™ products are manufactured under ISO 13485, CE, FCC, RoHS, and ISO 9001 certification. The SPE/PEM separation technology produces pure H₂ with no ozone, no carbon monoxide, and no caustic chemistry in the gas path. Every unit is factory-tested before dispatch.

Hydrogen is flammable at concentrations above 4% in air. Hydrogen Wellness™ inhalation devices deliver hydrogen at concentrations well below this threshold through a sealed gas path directly to a nasal cannula or face mask. The gas does not accumulate in the room. Sessions should take place in a normally ventilated space away from open flames.

Safety

Safety, built in.
Not bolted on.

Hydrogen Wellness™ products are engineered to deliver hydrogen-rich breathing and bathing environments without delivering any of the hazards historically associated with the term "Hydrogen Wellness". The user-facing stream is pure molecular hydrogen — never a flammable gas mixture.

Separated gas streams

PEM/SPE separation produces hydrogen and oxygen in independent channels. The cannula delivers 99.99% pure H₂ only — there is no oxyhydrogen mixture at the user.

Multi-layer cut-offs

Automatic shut-down on over-temperature, over-pressure or low water level. The unit fails safe by default.

Clean water cycle

Distilled or deionised water with a 365-day cycle and on-screen counter. UV sterilisation maintains reservoir quality between changes.

Studied at this dose

Published trials at the inhaled concentrations produced by consumer inhalers (2–4% H₂ in the inhaled mix) report no significant adverse effects.

When to consult a clinician first

Hydrogen Wellness™ products are wellness devices, not medical devices. Speak to a qualified clinician before using hydrogen inhalation if you are pregnant or breastfeeding, are under 18, have a serious cardiovascular, respiratory or neurological condition, use supplemental oxygen, are undergoing active cancer treatment, or take medication where oxidative stress plays a known clinical role.
