Key takeaways
- Both use PEM/SPE electrolysis to generate pure H₂ on demand.
- An inhaler delivers gas directly through a nasal cannula or mask.
- A bath system dissolves gas into bath water through a submerged head.
- The two units are sized differently — they are not interchangeable.
Operation
Inhalers run at ~600–3,000 ml/min of pure H₂ delivered through a small port. The user wears a cannula or mask; sessions usually run 30–120 minutes.
Bath systems produce a much larger gas volume routed into a submerged dissolution head. The user soaks in the tub; sessions usually run 20–30 minutes once the water reaches concentration.
Machine design
Inhaler chassis: small footprint, low-volume reservoir, single (or dual) outlet port sized for a cannula. Cooling is sized for continuous run-time of an hour or more at modest flow.
Bath chassis: larger plate area, larger source reservoir, dissolution head built for a tub, thermal envelope sized to hold maximum output across a saturation window.
Hydrogen delivery method
Inhalation delivers H₂ as a gas to the respiratory tract. Bathing delivers H₂ dissolved in water across the skin and the surrounding air column.
These are different delivery routes with different engineering targets — neither replaces the other. Many households operate both, on different cadences.
Spec sheet contrast
Inhaler key spec: H₂ flow rate in ml/min, purity in %, continuous run-time in minutes/hours.
Bath key spec: hydrogenated water flow rate in ml/min, sustained dissolved H₂ in ppb, saturation time to working concentration.
