Safety overview

Hydrogen wellness, used correctly, is safe.

Hydrogen is the smallest molecule in existence. No accumulation. No known adverse effects at the concentrations delivered by Hydrogen Wellness™ devices.

The question is whether the device delivering it is safe. That is where engineering matters.

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 inhalation 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.

When to talk to your doctor first

Hydrogen Wellness™ products are wellness devices, not medical devices. If you have a medical condition, are pregnant or take medication, talk to your doctor before using any new wellness product.
