Buy Hydrogen Bath Machines
Two purpose-built bath systems engineered for full-tub molecular hydrogen dissolution — Bath One™ and WZ-1™. 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. Bath One™ and WZ-1™ sit in the only correct architectural category: PEM/SPE bath systems built for the job.

WZ-1™
The dedicated residential bath system. Quieter operation, smaller footprint, optimised for single-tub households running daily sessions. Dissolves a standard tub in roughly 15–20 minutes.
- · PEM/SPE electrolysis
- · CE + RoHS certified
- · 12-month warranty
- · Free worldwide delivery
WZ-1™
The higher-capacity model — faster dissolution, larger reservoir, suited to back-to-back sessions and larger tubs. Used in residential master suites, recovery studios and small commercial installations.
- · PEM/SPE electrolysis
- · CE + RoHS certified
- · 12-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.
Hydrogen is generated inside the machine and piped through a submerged diffuser stone. Bubbles rise through the bath and dissolve on contact. Used by the WZ-1.
Hydrogen is dissolved into water inside the machine, then delivered into the bath as hydrogenated water at 3,500 ml/min. Used by Bath One (WZ-1).
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 Bath One™ 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.
Bath One™ (WZ-1) vs the Echo Revive — full spec
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.
Spa-grade · closed-loop circulation | Echo Revive US-designed · gas diffusion | |

| Delivery architecture | Closed-loop circulation — bath water drawn in, infused with hydrogen from a separate distilled water tank, returned to the bath at 3,750 ml/min | H₂ gas diffusion into bath water at 850 ml/min |
| Dissolved H₂ target | >2,000 ppb (confirmed) | Up to 1,600 ppb |
| Duty rating | Continuous | Continuous per session |
| Certifications | CE · FCC · RoHS · ISO 9001 · ISO 13485 | CE · RoHS · BPA Free |
| Format | Portable 14 kg benchtop | Floor unit with locking wheels |

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.
