How to compare hydrogen inhalation machines
Every reputable hydrogen inhaler produces molecular hydrogen through electrolysis, but the engineering behind that process varies dramatically. A meaningful comparison starts with the hydrogen output rate — measured in millilitres per minute of pure H₂ — and extends into how that output is produced, certified and sustained over the lifespan of the machine.
Look past the marketing headlines. A well-specified inhaler should publish its certified pure H₂ flow rate (not combined H₂+O₂), name the electrolysis technology (PEM/SPE, not alkaline), list its certification stack in full, and disclose the intended duty cycle. Manufacturers who publish this information openly are the ones worth comparing.
- Hydrogen output — pure H₂ ml/min
- Electrolysis type — PEM/SPE only
- Continuous-duty rating
- Certification stack (CE, FCC, RoHS, ISO)
- Build quality and stack lifespan
- Warranty and returns terms
- Delivery, duties and support model
- Price transparency vs distributor mark-up
Buyer decision framework
Match the machine to the routine. Solo daily use is well served by the QY-A900 or QY-A1200. If two people share the machine, choose one with a certified dual-cannula mode. If sessions run back-to-back for hours, you need a continuous-duty design like the QY-A1800 or QY-A3000.
Solo home routine
QY-A900 or QY-A1200. Certified 900–1,200 ml/min pure H₂, quiet operation, distilled water only.
Two users, one machine
QY-A1200 or QY-A1800 with dual-cannula splitter. Balanced flow for two simultaneous sessions.
High-frequency or multi-user
QY-A3000 with 3,000 ml/min combined output and continuous-duty stack for extended sessions.
Certifications and build quality
Certifications describe the hardware and its manufacturing process — not the therapeutic status of hydrogen inhalation. What you should insist on is an inhaler that documents CE marking, FCC Part 15 Subpart B compliance, RoHS material safety, and manufacturing under ISO 9001 and ISO 13485 quality management. The QY-A series is the only range at direct-price to carry all five.
Build quality is harder to see on a spec sheet. Look for stainless-steel gas paths, dual PEM stacks with independent temperature and pressure cut-offs, and a stated lifespan expressed in operating hours rather than a warranty period alone.
Warranty, delivery and support
Every inhaler ships with a 12-month manufacturer warranty from the day of delivery and a 30-day return window. Delivery is free worldwide with duties and taxes prepaid where the destination allows — the price you see is the price you pay.
Support is direct. WhatsApp Business, email, and telephone all reach the Hydrogen Machines team in Australia, not a distributor or third-party service loop.
How PEM electrolysis works
A proton exchange membrane sits between two electrodes. A DC voltage splits purified water into oxygen at the anode and hydrogen at the cathode. The membrane keeps the two gas streams separate, so the hydrogen leaving the machine is not mixed with oxygen.
The QY-A inhaler range, compared
Every machine in the range uses the same PEM/SPE electrolysis architecture, titanium-platinum electrodes and five-certification stack. What changes across the tier is stack area, sustained output and cannula-mode capacity.

How to read an inhaler spec sheet
Prioritise
The specs that decide daily satisfaction.
- Pure H₂ ml/min (not H₂+O₂ combined)
- PEM/SPE electrolysis — never alkaline / lye
- Continuous-duty rating
- Full certification stack including FCC Part 15
- Direct manufacturer support pathway
Consider
Second-order factors.
- Cannula design and comfort
- Session timer and control interface
- Reservoir capacity and refill frequency
- Noise level during operation
- Voltage range for travel use
Ignore
Common but meaningless signals.
- Combined H₂+O₂ output claims
- Health or therapeutic language
- Alkaline systems marketed as premium
- 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.
