Key similarities
- All dedicated bath machines target the same job: hydrogen into a full bathtub
- All sit beside the bath and connect via hose and diffuser
- All require feedwater management at the cell side
- All are general wellness equipment — none are registered medical devices
Key differences
- HERO Bath uses in-water hydrogenation; HERO Bath uses continuous gas diffusion
- HERO Bath 6 L/min has a 2.0 L tank and aluminium oxide standard filter and aeration heads; 316 stainless steel heads available on request
- Hydrogen Machines ships to supported destinations under the shipping policy with destination-specific DDP/DAP terms
- Many combined inhaler + bath units don't sustain >2000 ppb across a full bath; verify the spec
Which one fits you?
HERO Bath — dedicated PEM system, 6 L/min flow, sustained >2000 ppb across the bath.
HERO Bath — editorial range, gas-diffusion delivery, sustained >2000 ppb.

HERO Equipment and Documentation
Compare published specifications side by side.
- Model-specific laboratory documentation is available on the individual product pages.
- Compare the exact model's published electrolysis design and duty rating.
- Ask for certification documents for the exact model before purchasing.
- Direct pricing, 24-month machine warranty and tracked delivery under destination-specific shipping terms.
- Support handled directly by our own team — never through a distributor loop.
- A complete range: bathing, inhalation and hydrogen water, so the machine matches the routine.
Certifications and engineering claims describe hardware and manufacturing, not medical or therapeutic status.
HERO Bath 6 L/min specifications are manufacturer-stated; no certification claim is made for this model.
View all certifications →Across the category: clean the diffuser between sessions per the manual, drain the water trap on the cadence in the manual, run periodic cell rinses, and use clean feedwater at the cell. Hard-water regions benefit from an inline filter.

Report LH2025050017 covers HERO Inhaler 900, 1200, 1500, 2000 and Pro 3000. Check the measured outlet and test conditions; do not extend results to other models or untested flow rates.
Certifications, purity figures and engineering specifications describe hardware and manufacturing quality. Products are sold as general wellness devices, not FDA-approved — not medical devices, not TGA registered, and not intended to diagnose, treat, cure or prevent any disease.

Frequently asked questions
- Are combined inhaler + bath units a viable alternative?
- Usually no for bathing. An inhaler-sized cell split across two jobs delivers less hydrogen into the much larger water volume of a bath than a dedicated bath machine. Dedicated bath machines are purpose-built for that volume.
- How do I compare bath machines on output?
- Look at dissolved hydrogen sustained across the bath (ppb), not raw cell output. Cell output that doesn't dissolve into bath water doesn't help you.
- Is plumbing required?
- No — dedicated bath machines like the HERO Bath are free-standing units that run from a wall outlet and deliver hydrogen via hose and diffuser.
- Where can I read the technology overview?
- See the Hydrogen Bath Machines pillar — it covers PEM electrolysis, delivery, dissolution, types of systems and how to evaluate them.
