Safety, built in.
Not bolted on.
HHO™ products are engineered to deliver hydrogen-rich breathing and bathing environments without delivering any of the hazards historically associated with the term "HHO". 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
HHO™ 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 therapeutic role.
