Buy Hydrogen Bath Machines
The HERO Bath — a purpose-built bath system engineered for full-tub molecular hydrogen dissolution. Not adapted inhalers, not industrial Brown's-gas tanks: dedicated PEM/SPE chassis with the plate area, dissolution head and runtime curve sized for residential and spa-grade bathing.
Why dedicated bath systems
A bathtub holds roughly 100–200 litres of water. Dissolving enough molecular hydrogen across that volume in a sensible session window is a different engineering problem to feeding a cannula at 1 litre per minute. It requires a much larger membrane stack, a dissolution head designed for sub-surface diffusion, and a thermal envelope that can hold continuous output for 20+ minutes without throttling.
Repurposed inhalers cannot do this — the gas is delivered, but it bubbles out to atmosphere faster than it dissolves. Industrial Brown's-gas generators can produce the volume, but they introduce lye chemistry and were never designed for human-facing daily use. The HERO Bath sits in the only correct architectural category: PEM/SPE bath systems built for the job.

HERO Bath
The dedicated PEM/SPE hydrogen bath system. Dissolves a standard 100–200 L residential tub in roughly 10–15 minutes at >2,000 ppb, with a closed-loop dissolution head sized for daily use and back-to-back sessions. Quiet enough for residential bathrooms; capable enough for master suites, recovery studios and small commercial installations.
- · PEM/SPE electrolysis · 3,750 ml/min hydrogenated water
- · >2,000 ppb dissolved H₂ target
- · CE · FCC · RoHS · ISO 9001 · ISO 13485
- · 24-month warranty · free worldwide delivery
Two delivery architectures
Two different ways to get molecular hydrogen into a bath. Same molecule, different physics. Both are free-standing benchtop machines that sit beside a standard tub — no plumbing, no installation.
What dissolved hydrogen concentration actually means
Dissolved hydrogen is measured in parts per billion (ppb). A useful bathing concentration sits well above what a repurposed inhaler bubbling into a tub can produce. The scale below shows where the HERO Bath™ targets and why the architecture matters.
How a hydrogen bath machine installs
Free-standing beside a standard tub. Standard wall outlet. No plumbing, no drilling, no dedicated circuit, no installer required.
HERO Bath vs the Echo Revive — full spec
Comparison based on manufacturer-published engineering specifications.
The two dedicated hydrogen bath systems most commonly cross-shopped in this category. Both PEM/SPE, both direct-price. Certification depth, flow rate and price are where they differ.

| Purity Level / Output Concentration | >2,000 ppb dissolved H₂ (confirmed) | Up to 1,600 ppb |
| Membrane / Electrolysis Technology | PEM · titanium-platinum cell | Gas diffusion cell |
| Water Input Requirement | Separate distilled water tank | Bath water only |

How to read a hydrogen machine spec sheet
Prioritise
What actually predicts satisfaction.
- Continuous-duty rating
- Confirmed dissolved H₂ (ppb)
- Corrosion-resistant wetted materials
- Warranty length + direct support
- No-plumbing, free-standing format
Consider
Home-specific factors.
- Footprint beside your bath
- Voltage range for international moves
- Reservoir volume and refill cadence
- Noise during operation
- Local service reachability
Ignore
Marketing surface area.
- Peak flow with no duty rating
- Health / therapeutic language
- 'Medical-grade' with no certificate
- Reviews without purchase verification
- Bundled 'protocols' padding the price
What each certification means
- CE
- European Conformity. Covers electrical safety, EMC and applicable equipment directives for the European market.
- FCC Part 15 Subpart B
- US electromagnetic emissions standard. Independently lab-tested — conducted and radiated emissions across the full frequency range.
- RoHS
- Restriction of Hazardous Substances. Limits lead, mercury, cadmium and other restricted materials in electronic assemblies.
- ISO 9001
- Manufacturing quality management system. Documented processes for design, production and continuous improvement.
- ISO 13485
- Quality management system for medical-device-grade manufacturing. Referenced here for hardware manufacturing rigour only.
Certifications describe hardware and manufacturing quality only. They are not medical or therapeutic claims. Hydrogen Machines products are general wellness devices.
How each certification is earned
A certification mark is the end of a documented process, not a sticker. Here is the pipeline every Hydrogen Machines model runs through before it ships.
- 1. Design. EMC, safety and materials specified at the schematic stage.
- 2. Sample build. Production-representative units sent to accredited labs.
- 3. Lab testing. Conducted / radiated emissions, dielectric strength, materials scan.
- 4. Report. Independent lab issues a signed test report with pass criteria.
- 5. Mark. CE / FCC / RoHS marks applied to compliant production runs.
