Hydrogen modality — inhalation and bathing
Two consumer modalities sit at the centre of everything on this site. Hydrogen inhalation delivers molecular hydrogen gas through a nasal cannula during a seated session, specified in millilitres per minute of hydrogen flow. Hydrogen bathing dissolves hydrogen into an ordinary filled bath, specified by dissolved hydrogen concentration in the water.
Neither modality applies heat, light or pressure as its mechanism, and neither is presented as superior. They are different formats with different logistics: inhalation suits people who can sit for twenty to sixty minutes; bathing suits people who already bathe regularly and prefer passive, whole-body sessions.
Hydrogen-rich water is covered as a related third format, and is usually the lowest-friction entry point.
PEM purity — electrolysis, contaminants and levels
All systems here generate hydrogen by PEM/SPE electrolysis: pure or distilled water is split across a solid polymer membrane, so hydrogen evolves on one side and oxygen on the other. There is no caustic liquid electrolyte and no stored gas.
Purity describes what leaves the machine. The categories that matter are residual oxygen, water-vapour carry-over and any material shed from the cell stack or gas path. A purity figure means little without a method attached: who measured it, with what instrument, against which reference.
Our inhalation systems have been independently purity-tested by a third-party laboratory (QTT reports LH2025050017 and LH2025050018). Purity results and certification marks such as CE, FCC and RoHS describe hardware, materials and manufacturing quality — not medical or therapeutic status.
Devices — inhalers and bath systems
The inhalation range spans portable and fixed units across a series of hydrogen flow tiers, all built on the same PEM/SPE cell architecture. The practical differences are flow rate, session ergonomics, noise, water handling and maintenance effort.
The bath range centres on the HERO Bath generator, which sits beside a filled bath and feeds hydrogen through a diffuser. Setup is non-permanent and requires no plumbing change.
Because specifications are measured on different scales per modality, comparisons only make sense inside a modality — millilitres per minute of gas cannot be compared with parts per million in water.
Scientific mechanisms
Published research on molecular hydrogen is mechanism-focused and exploratory. The most commonly examined areas are oxidative-stress signalling, inflammatory markers and mitochondrial function, studied because hydrogen is a very small, neutral, highly diffusible molecule.
Much of this work is small, short or preclinical, and studies specify a delivery route, so findings from one modality do not transfer automatically to another. We index the sources so readers can go to them directly rather than relying on summaries.
Nothing in this literature should be read as evidence that any device treats, prevents or cures a condition.
Consumer guidance
Choosing between formats is a routine question before it is a specification question: how much uninterrupted sitting time is realistic, whether a bath is used regularly, and how much maintenance effort is acceptable.
Owners generally fold hydrogen into an existing habit rather than treating it as an event, so consistency — and therefore device noise, water handling and cleaning — often matters more than a headline number.
