Specifications at a glance
| If you're new to hydrogen | If you know what you want | |
|---|---|---|
| Step 1 — Application | Inhalation, bath or drinking water? | Same question, more specific |
| Step 2 — Users per session | One, two, or three+ | Same — and whether sessions are concurrent |
| Step 3 — Setting | Home or professional? | Home, studio, clinic, spa, retreat |
| Step 4 — Output class | Match output to users + session length | Match output to duty cycle + concurrent sessions |
| Step 5 — Budget | Entry / mid / premium band | Capital + running cost + warranty cover |

Key similarities
- Every Hydrogen Machines product uses PEM / SPE cell technology at high purity
- Every product carries hardware certifications (CE, FCC, RoHS where applicable)
- Every product ships to supported destinations under the shipping policy with a 24-month warranty
Key differences
- Inhalers vs bath machines vs combined inhale-and-drink machines are different categories
- Output classes (300 ml/min entry → 3000 ml/min multi-user) suit different protocols
- Home-portable vs continuous-duty professional is a different engineering class
Which one fits you?
Start with the HERO Inhaler 900 or HERO Inhaler 1200 — quiet, well-certified, easy to live with. See the beginners guide for the full reasoning.
HERO Inhaler 1200 with the included Y connector for two-user sessions. Quietest in the range, designed for long evening sessions.
HERO Inhaler 2000 — Combined 2,000 ml/min · Pure H₂ 1,333 ml/min in a compact chassis. Best step up before moving to multi-user.
HERO Inhaler Pro 3000 multi-outlet platform — see the professional guide.
HERO Dual 20 — dual-mode inhalation and ≥3000 ppb drinking water from one machine.
HERO Bath (dedicated bath system) or HERO Bath (bath system, editorial range). See the Hydrogen Bath Machines pillar.
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.
All recommended machines carry CE (EU electrical and EMC), FCC (US EMC) where applicable, RoHS and ISO 9001 / ISO 13485-aligned manufacturing. Certifications describe hardware and manufacturing standards, not therapeutic status.
View all certifications →All Hydrogen Machines products use distilled or RO water and a periodic cell-rinse cycle on the cadence in the manual. Continuous-duty machines should add an annual professional inspection.

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
- What's the single best hydrogen machine?
- There isn't one. The right machine depends on application, users per session and setting. For a beginner solo home user it's typically the HERO Inhaler 900 or HERO Inhaler 1200; for a clinic it's the HERO Inhaler Pro 3000; for bathing it's the HERO Bath.
- Should I buy a combined inhalation + bath machine?
- Usually no. Dedicated inhalers and dedicated bath machines outperform combined units in their respective applications. The HERO Dual 20 is the exception — and it pairs inhalation with drinking water, not bathing.
- Is more output always better?
- No — see High output vs low output. More output means more hydrogen per minute, which matters most for multi-user or short sessions. Solo, long sessions are usually more comfortable at lower output.
- Do I need certifications?
- You want them. CE and FCC tell you the machine has been tested against recognised electrical and EMC standards. Treat the absence of either as a red flag.
