Q: What is the difference between the QY-F6000 and QY-F8400?

Both machines use the same PEM/SPE electrolysis architecture, the same 7-stage steam and water separation system, and the same certification stack (CE · FCC Part 15 Subpart B · RoHS · ISO 9001 · ISO 13485). The difference is output capacity and simultaneous-user configuration. QY-F6000 (H6 Pro™): Pure H₂: up to 4,000 ml/min — fully adjustable Pure O₂: up to 2,000 ml/min Combined H₂+O₂: up to 6,000 ml/min Simultaneous users: up to 3 QY-F8400 (H8 Pro™): Pure H₂: up to 5,600 ml/min — fully adjustable Pure O₂: up to 2,800 ml/min Combined H₂+O₂: up to 8,400 ml/min Simultaneous users: 2 independent control panels (each panel separately adjustable for back-to-back or parallel sessions) Output on both machines is fully adjustable between minimum and maximum via the touchscreen control panel. Published figures are maximum rated output only. The 2:1 H₂:O₂ ratio is maintained at all output levels as two completely separated independent gas streams. Choose the QY-F6000 for single-user professional, athlete and premium home use. Choose the QY-F8400 where two independent users need to run separately controlled sessions at the same time — typical of multi-station wellness studios, wellness rooms and spa environments.

Question 1

What is a hydrogen inhalation machine?

Accepted Answer

A hydrogen inhalation machine is a wellness appliance that produces molecular hydrogen gas (H₂) for inhalation through a nasal cannula. The Hydrogen Wellness™ H6 Pro™ uses PEM/SPE electrolysis to split purified water into separated hydrogen and oxygen streams — delivering up to 4,000 ml/min of 99.99% pure H₂ — fully adjustable — for daily home wellness routines. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 2

What is a molecular hydrogen machine?

Accepted Answer

"Molecular hydrogen machine" is the generic engineering term for any device that produces molecular hydrogen (H₂) — the smallest stable molecule in nature. It covers both hydrogen inhalation machines (where the H₂ is delivered as a gas via cannula) and hydrogen water systems (where H₂ is dissolved into drinking or bath water). The Hydrogen Wellness™ range includes both formats. General wellness device. Not a medical device.

Question 3

What is a hydrogen bath machine?

Accepted Answer

A hydrogen bath machine is a wellness appliance that produces a high flow of hydrogen-rich water for use in a bath. Bath One™ is a dedicated hydrogen bath machine engineered for residential use — its titanium-platinum electrolytic cell infuses bath water with molecular hydrogen at 3,750 ml/min for a daily hydrogen-rich bathing routine. General wellness device. Not a medical device.

Question 4

What is the difference between a hydrogen bath machine and a hydrogen bath system?

Accepted Answer

The two terms are used interchangeably in the industry. A hydrogen bath machine refers to the appliance itself — the unit that produces hydrogen-rich water. A hydrogen bath system can describe the same appliance, or the wider setup (machine plus tubing, hoses and bath integration). Bath One™ is supplied as a complete hydrogen bath machine and hydrogen bath system in one — the appliance, hoses and fittings required for daily home hydrogen bathing.

Question 5

How does a hydrogen inhalation machine work?

Accepted Answer

A hydrogen inhalation machine produces molecular hydrogen (H₂) on demand through water electrolysis. The H6 Pro™ uses a Proton Exchange Membrane (PEM/SPE) electrolysis stack — current is applied across the membrane, water (H₂O) is split into hydrogen and oxygen, and the membrane keeps the two gas streams completely separated. The pure H₂ stream is dried through a 7-stage steam and water separation circuit, then delivered to the user through a nasal cannula at the chosen flow rate. General wellness device. Not a medical device.

Question 6

What is the QY-F series — and how does it differ from standard hydrogen inhalers?

Accepted Answer

A hydrogen inhalation machine uses PEM/SPE (Proton Exchange Membrane / Solid Polymer Electrolyte) electrolysis to split purified water into its component gases — molecular hydrogen (H₂) and oxygen (O₂) — in separated, independent streams. The QY-F series differs from standard hydrogen inhalers in four specific ways: 1. Output architecture — dual separated streams. PEM/SPE electrolysis produces H₂ and O₂ as completely separated gas streams. The QY-F6000 produces up to 4,000 ml/min pure H₂ — fully adjustable — and 2,000 ml/min pure O₂ independently. You choose which stream — or which combination — to inhale. Inhale pure H₂ only. Or inhale the combined H₂+O₂ flow in a 2:1 ratio — your choice at every session. This is fundamentally different from alkaline electrolysis devices that produce a mixed gas (oxyhydrogen or Brown's Gas) with no separation — delivering hydrogen and oxygen simultaneously with no option to select H₂ only. 2. Professional output levels. The QY-F6000 delivers up to 4,000 ml/min pure H₂ — fully adjustable — the higher-output range referenced in published research. Most standard hydrogen inhalers deliver 150–600 ml/min total output. The QY-F6000 delivers up to 4,000 ml/min pure H₂ — fully adjustable — alone, with an additional 2,000 ml/min pure O₂ stream available independently. 3. Seven-stage steam and water separation. The QY-F series removes moisture at seven progressive stages before the gas reaches the cannula — delivering consistently dry hydrogen across the full session duration, including back-to-back sessions. Standard inhalers typically use a single water trap. 4. ISO 13485 manufacture. The quality management standard of the medical device industry — covering how the factory is run, not just the product that leaves it. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 7

What is the difference between inhalation pure H₂ and inhalation the combined H₂+O₂ flow?

Accepted Answer

PEM/SPE electrolysis splits water in a 2:1 ratio — two parts hydrogen to one part oxygen by volume. The QY-F6000 produces these as two completely separated, independent gas streams: H₂ stream: up to 4,000 ml/min pure molecular hydrogen — fully adjustable O₂ stream: 2,000 ml/min pure oxygen You have three options at every session: Option 1 — Pure H₂ only. Inhale from the hydrogen outlet only. Up to 4,000 ml/min pure molecular hydrogen — fully adjustable. No oxygen co-delivery from the machine — you inhale ambient air normally alongside the H₂ stream via nasal cannula. This is the mode most directly studied in peer-reviewed hydrogen inhalation research — where the intervention variable is molecular hydrogen specifically. Option 2 — Combined H₂+O₂ (2:1 ratio). Inhale from both outlets simultaneously — up to 4,000 ml/min H₂ and 2,000 ml/min O₂ combined in a 2:1 ratio. Total combined flow: 6,000 ml/min. Some users and practitioners prefer this mode for longer sessions or where supplemental oxygen delivery alongside hydrogen is the protocol objective. Option 3 — O₂ only. Use the oxygen stream independently from the hydrogen stream. The ability to select between these modes — and to use both streams independently — is a function of the separated PEM/SPE architecture. It is not available on alkaline electrolysis devices or Brown's Gas machines, which deliver a fixed mixed gas with no stream separation. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 8

What is Brown's Gas — and is that what the QY-F series produces?

Accepted Answer

No. The QY-F series does not produce Brown's Gas. Brown's Gas (also called oxyhydrogen or HHO) is a mixed gas produced by alkaline electrolysis — hydrogen and oxygen combined in the production cell with no separation. It exits as a single mixed stream. The QY-F series uses PEM/SPE electrolysis — a fundamentally different technology. The PEM membrane separates the hydrogen and oxygen production cells completely. They never mix in the machine. They exit as two independent, pure gas streams. The difference matters for two reasons: 1. Purity. PEM/SPE produces 99.99% pure H₂ in the hydrogen stream. No oxygen contamination, no electrolyte carry-over, no ozone, no chlorine compounds. Brown's Gas devices — particularly alkaline electrolysis units — can carry electrolyte vapour and other contaminants in the mixed gas stream. 2. Protocol control. PEM/SPE separated streams allow you to select pure H₂, combined H₂+O₂, or pure O₂ independently. Brown's Gas devices deliver a fixed mixture with no user control over the gas composition. The QY-F series machines display both output figures clearly on the product page: H₂: [X] ml/min pure H₂ O₂: [X] ml/min pure O₂ If a hydrogen inhaler seller publishes only a single output figure without specifying whether it is pure H₂ or mixed gas — ask the question before purchasing. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 9

What is the 7-stage steam and water separation system — and why does it matter?

Accepted Answer

PEM/SPE electrolysis produces hydrogen gas in a water environment. Without separation, moisture — water vapour, steam and micro-droplets — travels with the hydrogen gas stream toward the cannula. Moisture in the gas stream causes two problems in practice: 1. Discomfort. Warm, wet gas is uncomfortable to inhale through a nasal cannula — particularly across sessions of 30 minutes or longer. 2. Inconsistency. Moisture content in the gas stream varies across a session as the machine warms up and as the water level changes. An inconsistent gas stream means an inconsistent session experience. --- What the 7 stages actually do: The QY-F series removes moisture progressively — at seven sequential points between the electrolysis cell and the cannula outlet. Each stage removes a portion of the remaining moisture. By stage seven, the gas reaching the cannula is consistently dry. In practice across a session: Stage 1 — Primary water trap. Captures the bulk of liquid water immediately downstream of the electrolysis cell before it enters the gas circuit. Stage 2 — Cooling circuit. Reduces gas temperature, causing water vapour to condense and drop out of the gas stream. Stage 3 — Secondary moisture separator. Captures condensed droplets produced in Stage 2 before they re-enter the gas flow. Stage 4 — Desiccant or membrane drying layer. Absorbs residual water vapour from the gas stream at a molecular level. Stage 5 — Fine particulate and aerosol filter. Removes micro-droplets that passed through earlier stages as suspended aerosol. Stage 6 — Final moisture check. A second desiccant or membrane stage capturing any remaining vapour after Stage 5. Stage 7 — Delivery line water trap. Captures any condensation that forms in the tubing between the machine and the cannula — particularly relevant in longer sessions where tubing temperature drops. --- Why it matters for sustained use: A single water trap — the standard on most hydrogen inhalers — captures the initial liquid water but does not address vapour, aerosol, condensation in the delivery line or temperature-driven moisture variation across a session. In a 20-minute home session this is manageable. In a 60–90 minute extended session — or in back-to-back sessions in a wellness studio or spa environment — it becomes a material comfort and consistency issue. The 7-stage system maintains consistent, dry gas delivery from the first minute of a session to the last — and across consecutive sessions without a drying-out period between them. This is why the 7-stage specification appears on the QY-F series and not on standard consumer hydrogen inhalers — it is an engineering requirement for sustained professional and continuous-duty use, not a home wellness feature. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 10

Is the QY-F6000 suitable for home use, or is it clinic-only?

Accepted Answer

Yes. The H6 Pro™ is designed as a premium home hydrogen machine: quiet (<45 dB), universal 100–240 V input, three simultaneous cannula outputs for family or shared use, and a clean cabinet finish that suits a living space rather than a professional-only environment.

Question 11

What is the difference between the QY-F6000 and QY-F8400?

Accepted Answer

Both machines use the same PEM/SPE electrolysis architecture, the same 7-stage steam and water separation system, and the same certification stack (CE · FCC Part 15 Subpart B · RoHS · ISO 9001 · ISO 13485). The difference is output capacity and simultaneous-user configuration. QY-F6000 (H6 Pro™): Pure H₂: up to 4,000 ml/min — fully adjustable Pure O₂: up to 2,000 ml/min Combined H₂+O₂: up to 6,000 ml/min Simultaneous users: up to 3 QY-F8400 (H8 Pro™): Pure H₂: up to 5,600 ml/min — fully adjustable Pure O₂: up to 2,800 ml/min Combined H₂+O₂: up to 8,400 ml/min Simultaneous users: 2 independent control panels (each panel separately adjustable for back-to-back or parallel sessions) Output on both machines is fully adjustable between minimum and maximum via the touchscreen control panel. Published figures are maximum rated output only. The 2:1 H₂:O₂ ratio is maintained at all output levels as two completely separated independent gas streams. Choose the QY-F6000 for single-user professional, athlete and premium home use. Choose the QY-F8400 where two independent users need to run separately controlled sessions at the same time — typical of multi-station wellness studios, wellness rooms and spa environments. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 12

What membrane options are available — German PEM or DuPont N115 — and which should I choose?

Accepted Answer

The QY-F series is supplied with one of two proton exchange membrane options at order: 1. German PEM — the standard specification. A high-grade proton exchange membrane manufactured to industrial green-hydrogen specification. Suited to standard professional, athlete and premium home use at the full published output range. 2. DuPont Nafion N115 — the upgrade specification. Nafion N115 is the reference perfluorosulfonic acid membrane used in industrial PEM electrolysis and fuel cell research worldwide. Specified where the longest possible stack life and the highest membrane chemical stability are commercial priorities — typically multi-station wellness studios, spa environments and continuous-duty installations. Both membranes deliver the same rated output (up to 4,000 ml/min pure H₂ on the QY-F6000 and up to 5,600 ml/min pure H₂ on the QY-F8400 — fully adjustable in each case) and the same 99.99% H₂ purity. The stack is rated 10,000+ hours under normal operating conditions on either membrane. For most buyers the German PEM specification is the correct choice. Select the DuPont N115 upgrade where continuous-duty commercial use and maximum membrane lifetime are the deciding factors. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 13

How does the oxyhydrogen dual-output system work — pure H₂ mode vs combined H₂+O₂ double suction?

Accepted Answer

The QY-F6000 produces two independent gas streams: H₂: up to 4,000 ml/min pure H₂ — fully adjustable O₂: 2,000 ml/min pure O₂ Total combined flow: 6,000 ml/min (H₂+O₂ combined) The QY-F8400 produces: H₂: up to 5,600 ml/min pure H₂ — fully adjustable O₂: 2,800 ml/min pure O₂ Total combined flow: 8,400 ml/min (H₂+O₂ combined) These figures reflect separated PEM/SPE electrolysis output — not mixed gas output. Pure H₂ and pure O₂ are produced independently and delivered through independent outlets. A Proton Exchange Membrane sits between two electrodes inside the electrolysis stack. When current is applied, water splits into hydrogen and oxygen, and the membrane only allows protons (H⁺) to cross. This means the hydrogen stream coming out is essentially free of oxygen contamination — purity is independently testable at 99.99%+. PEM is the same technology used in industrial green-hydrogen production and is the modern alternative to older alkaline electrolysis. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 14

What water do I use, and how often do I change it?

Accepted Answer

The H6 Pro™ uses distilled or deionised water in its internal reservoir. Tap water contains minerals that will scale the electrolysis stack and shorten its life. The on-screen water-cycle counter tracks runtime; the recommended full water change is once every 365 operating days under normal use, with a top-up roughly every 100–200 hours.

Question 15

How loud is it?

Accepted Answer

The H6 Pro™ has three user-selectable speed modes; on the lowest mode it is quiet enough for a wellness room or bedroom setting. The unit ships with vibration-damping feet to minimise transfer noise to floors and benches.

Question 16

What's in the box?

Accepted Answer

The unit, three nasal cannulas, power cable for your destination region, hydration humidifier bottles, water filling bottle, dust filter, quick-start guide and full user manual.

Question 17

What is the warranty?

Accepted Answer

12 months manufacturer warranty against defects, covering the electrolysis stack, electronics and pumps. Consumables (cannulas, filters, water bottles) are not covered. Extended warranties are available on bulk orders.

Question 18

What is the power consumption and voltage?

Accepted Answer

The H6 Pro™ is supplied for either 110V (60Hz) or 220V (50Hz) destination, configured at order. Rated power draw is approximately 380W at full output — comparable to a desktop computer. The unit can run on standard mains outlets without dedicated circuits.

Question 19

How big and heavy is it?

Accepted Answer

Approximate dimensions: 410 × 320 × 480 mm. Net weight ~22 kg, gross shipping weight ~28 kg in carton. It sits comfortably on a wellness-room trolley or low bench.

Question 20

The QY-F6000 delivers up to 4,000 ml/min pure H₂ — fully adjustable — most inhalers deliver under 1,000 ml/min. What does that output differential actually mean in practice?

Accepted Answer

The output figure determines how much molecular hydrogen reaches the respiratory tract per minute of session time. A 60-minute session at up to 4,000 ml/min pure H₂ delivers materially more total H₂ at the source than a 60-minute session at 300–600 ml/min total mixed-gas output — which is the typical specification of consumer-tier hydrogen inhalers. In practice this affects three things: 1. Session length to reach a given total volume. Lower output means longer sessions to deliver an equivalent quantity of H₂. The QY-F6000 reaches the H₂ volumes referenced in published research inside standard 30–60 minute session windows. 2. Multi-user capability. The QY-F6000 supports up to three simultaneous cannula outputs. The QY-F8400 supports two independently controlled users via separate control panels. Consumer inhalers at sub-1,000 ml/min cannot meaningfully serve multiple users at the same time. 3. Adjustability headroom. Because output is fully adjustable between minimum and maximum, a machine rated up to 4,000 ml/min pure H₂ can run at a lower setting for shorter, lighter sessions and at maximum for longer sessions — without operating at the upper limit of its capability for the entire session. Output on both QY-F models is fully adjustable via the touchscreen control panel. Published figures are maximum rated output only. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 21

How does the QY-F series compare to the QY-A series — same manufacturer, different model tier. What specifically is different?

Accepted Answer

The QY-A series and the QY-F series are produced by the same manufacturer but sit at different tiers of the hydrogen inhalation product line. The QY-A series is the entry tier — lower rated output, single-user configuration, a simplified moisture separation stage and a reduced certification scope. It is positioned for personal home wellness use. The QY-F series — QY-F6000 (H6 Pro™) and QY-F8400 (H8 Pro™) — is the performance tier: Output. QY-F6000 produces up to 4,000 ml/min pure H₂ and up to 2,000 ml/min pure O₂ as two completely separated independent gas streams (up to 6,000 ml/min combined H₂+O₂) — fully adjustable. QY-F8400 produces up to 5,600 ml/min pure H₂ and up to 2,800 ml/min pure O₂ (up to 8,400 ml/min combined) — fully adjustable. Separation. 7-stage steam and water separation between the electrolysis cell and the cannula outlet — versus a single water trap on entry-tier machines. Multi-user architecture. QY-F6000 supports up to 3 simultaneous users; QY-F8400 ships with 2 independent control panels each separately adjustable. Certification. Full stack: CE · FCC Part 15 Subpart B · RoHS · ISO 9001 · ISO 13485. Membrane. German PEM standard with DuPont Nafion N115 available as an upgrade. Stack rated 10,000+ hours. If the use case is single-user home wellness at modest output, the QY-A is the correct tier. If the use case is professional, athlete wellness, multi-user or sustained session use, the QY-F series is the correct tier. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 22

The QY-F6000 is ISO 13485 manufactured — the same quality management standard used by regulated medical device makers. What does that mean for build quality and reliability?

Accepted Answer

ISO 13485 is the international quality management standard for organisations that design and manufacture medical devices. It governs how the factory is run — not just how the finished product is tested. Applied to the QY-F series, this means: Controlled design process. Every change to the product — components, suppliers, electronics, firmware — is documented, reviewed and traceable. Documented manufacturing controls. Each unit is built against a controlled process specification, with traceability of critical components (electrolysis stack, PEM membrane, power electronics) back to batch and supplier. Factory testing on every unit. Every machine is tested against specification before dispatch — not by sample, by unit. Non-conformance and corrective action procedures. If a fault is detected in the field, the root cause is documented and the manufacturing process is updated — not patched silently. For the buyer this translates into consistent unit-to-unit build quality, the certification stack required for commercial deployment (wellness studios, spas, longevity centres in multiple jurisdictions), and a manufacturing audit trail behind every unit shipped. The QY-F series carries the full certification set: CE · FCC Part 15 Subpart B · RoHS · ISO 9001 · ISO 13485. ISO 13485 sits alongside the technical certifications — it is the standard that governs how the product is built, while the others certify what the finished product complies with electrically and materially. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 23

Who actually buys the QY-F6000 and QY-F8400 — what are the typical use cases?

Accepted Answer

Elite and serious amateur athletes establishing a daily post-training wellness routine. Wellness studios and longevity practices running multi-user sessions. High-performance training centres deploying hydrogen inhalation alongside cryo, compression and normobaric altitude. See the full breakdown at hydrogenwellness.co/athletes

Question 24

What is the 7-stage separation system and why don't standard inhalers have it?

Accepted Answer

The 7-stage steam and water separation system removes moisture from the hydrogen gas stream in seven sequential stages between the electrolysis cell and the cannula outlet — primary water trap, cooling circuit, secondary separator, desiccant layer, aerosol filter, final vapour check, delivery line water trap. The result is consistently dry hydrogen gas from the first minute of a session to the last, and across consecutive sessions without a drying-out period between them. Standard consumer hydrogen inhalers do not have this stage architecture because the typical home use case — a 20-minute session, once or twice per day, single user — does not generate the cumulative moisture load that a longer or multi-user session produces. A single water trap is sufficient for short-duration use. The 7-stage system becomes a material engineering requirement in three scenarios: 1. Sustained sessions of 60–90 minutes or longer, where moisture variation across the session degrades comfort and consistency. 2. Back-to-back sessions in wellness studios, spas and wellness rooms, where there is no opportunity for the gas circuit to dry out between users. 3. Multi-user operation, where two or three cannulas are running simultaneously and the moisture load on the separation system is correspondingly higher. This is why the 7-stage specification appears on the QY-F series and not on entry-tier consumer hydrogen inhalers — it is an engineering requirement for sustained professional and continuous-duty use, not a home wellness feature. General wellness device. Not a medical device. No claim is made to diagnose, treat, cure or prevent any disease or medical condition.

Question 25

What is molecular hydrogen (H₂) and why is it studied for wellness?

Accepted Answer

Molecular hydrogen is the smallest, lightest molecule in the universe — two hydrogen atoms bonded together (H₂). It is a colourless, odourless, tasteless gas that is non-toxic at the concentrations used for inhalation. Research interest accelerated after a 2007 Nature Medicine paper by Ohsawa and colleagues, in which H₂ was molecularly studied in cell and animal models. Since then more than 2,000 peer-reviewed publications, including over 200 human studies, have explored its effects across a wide range of organ systems. The Molecular Hydrogen Institute and similar bodies treat H₂ as an emerging area of wellness and physiological research rather than as a medical treatment.

Question 26

How is the dose of inhaled hydrogen measured?

Accepted Answer

Two numbers matter: flow rate (millilitres of H₂ per minute, ml/min) and concentration in the inhaled gas mix (%). The QY-F6000 (H6 Pro™) delivers up to 4,000 ml/min of 99.99% pure H₂ — fully adjustable — as an independent gas stream, with up to 2,000 ml/min pure O₂ available independently (up to 6,000 ml/min combined). The QY-F8400 (H8 Pro™) delivers up to 5,600 ml/min pure H₂ — fully adjustable. Typical sessions referenced in the literature range from 30 to 120 minutes; durations vary by study. Volume differs fundamentally from drinking hydrogen water, where total H₂ delivered per session is measured in milligrams. Inhalation can deliver multiple grams of H₂ over the course of a single sitting.

Question 27

Does H₂ have any effect on healthy people, or only on illness?

Accepted Answer

Published studies in healthy adults have looked at markers such as exercise performance, perceived fatigue, sleep quality and biological markers studied in the literature. Results are mixed and trial sizes are generally small, but several show measurable shifts in redox markers after H₂ exposure. This is consistent with the wellness framing: H₂ is studied as a modulator of normal physiology, not as something that 'treats' a healthy person.

Question 28

How long does H₂ stay in the body after a session?

Accepted Answer

H₂ diffuses rapidly. After inhalation stops, blood and tissue H₂ levels return to baseline within roughly 30 to 60 minutes, depending on the study. Because H₂ leaves the body so quickly, repeated or sustained sessions are typically used in published research rather than single one-off exposures.

Question 29

Why inhale hydrogen instead of drinking hydrogen water?

Accepted Answer

It comes down to total volume of H₂ delivered. A glass of well-prepared hydrogen-rich water typically delivers about 1–2 mg of H₂. A 60-minute inhalation session at up to 4,000 ml/min pure H₂ (QY-F6000) delivers in the region of 24 grams of H₂ at the source — orders of magnitude more total hydrogen available to the body. The QY-F8400 at up to 5,600 ml/min pure H₂ delivers proportionally more again. Output is fully adjustable between minimum and maximum on both models. Drinking H₂ water remains useful for continuous low-dose exposure throughout the day. Inhalation is the method used in the majority of higher-volume published wellness studies.

Question 30

What is hydrogen bathing — and how does it compare?

Accepted Answer

Hydrogen bathing dissolves H₂ into bath water, where it can be absorbed transdermally and inhaled in low concentrations from the steam above the bath. The dose delivered systemically is lower than direct inhalation, but bathing is popular for relaxation and skin-focused wellness routines. Many spas and wellness centres offer all three modalities side-by-side.

Question 31

Where does the H6 Pro™ fit in this spectrum?

Accepted Answer

The H6 Pro™ (QY-F6000) sits at the performance tier of consumer and professional-grade inhalers: up to 4,000 ml/min pure H₂ — fully adjustable — at 99.99% purity, with up to 2,000 ml/min pure O₂ available as an independent stream (up to 6,000 ml/min combined H₂+O₂), and three simultaneous user outputs. That makes it suitable for wellness studios, longevity studios, athlete wellness rooms, and serious home use where multiple family members share sessions. The H8 Pro™ (QY-F8400) extends this to up to 5,600 ml/min pure H₂ with two independently controlled user panels for multi-station deployments.

Question 32

Does ml/min or ppm matter more?

Accepted Answer

For inhalation, ml/min (flow rate) is the more meaningful number — it tells you how much H₂ enters the inhaled air per minute. ppm is more relevant when measuring H₂ dissolved in water. Be cautious of marketing that mixes the two units; they describe different things.

Question 33

How does session length affect outcomes?

Accepted Answer

Published protocols range from 20-minute single sessions up to several hours daily over multi-week trials. There is no single 'correct' duration — most wellness users start at 30–60 minutes once or twice per day and adjust based on how they feel. Because H₂ clears the body quickly, more frequent shorter sessions are not obviously worse than longer single sessions.

Question 34

Is hydrogen inhalation safe?

Accepted Answer

H₂ has been used by professional divers for decades at far higher pressures than wellness inhalation. The studies published to date — including extended-duration human exposures — report no significant adverse effects at the concentrations produced by consumer inhalers (typically 2–4% H₂ in the inhaled mix when blended with room air via cannula). The H6 Pro™ produces 99.99% pure H₂ as an independent gas stream separated from the O₂ stream via PEM/SPE electrolysis, so there is no mixed oxyhydrogen (Brown's Gas) flammable mixture exiting the cannula at the user's nose. The device includes over-temperature, over-pressure and water-level safety cut-offs.

Question 35

Are there side effects?

Accepted Answer

Reported side effects in published trials are uncommon and mild — most often a brief dry sensation in the nose or throat. Some users describe a feeling of relaxation or mild tiredness during the first sessions, which typically settles. If you experience anything unexpected, stop the session and speak to a clinician.

Question 36

Who should NOT use a hydrogen inhaler without medical advice?

Accepted Answer

Speak to a qualified clinician before using hydrogen inhalation if you: • are pregnant or breastfeeding • are under 18 • have a serious cardiovascular, respiratory or neurological condition • use supplemental oxygen or any home respiratory device • are undergoing active cancer treatment • are on medication where oxidative stress plays a known role in the prescribed therapy (some chemotherapies, for example) The H6 Pro™ is a general wellness device. It is not intended to diagnose, treat, cure or prevent any disease or medical condition.

Question 37

Can H₂ interact with medications?

Accepted Answer

There are no well-documented direct drug interactions, but because published research describes H₂ as a redox modulator, anyone on chronic medication should discuss use with their prescriber — particularly for chemotherapy, immunosuppressants, or therapies that intentionally rely on oxidative stress.

Question 38

Is the device safe to leave running?

Accepted Answer

The H6 Pro™ is rated for continuous operation and includes automatic shut-offs for low water, over-temperature and over-pressure. As with any electrical appliance we recommend not leaving it unattended for extended periods and following the maintenance schedule in the manual.

Question 39

What about pure oxygen — does this device produce oxygen too?

Accepted Answer

The H6 Pro™ uses PEM/SPE (Proton Exchange Membrane / Solid Polymer Electrolyte) separation, which means the hydrogen and oxygen streams are produced separately. The oxygen by-product is safely vented; the cannula delivers high-purity H₂ only. This is what distinguishes a true membrane-separated hydrogen inhaler from older un-separated electrolysers that deliver a flammable 2:1 H₂/O₂ mixture and carry very different safety considerations.

Question 40

How much research exists on H₂?

Accepted Answer

More than 2,000 peer-reviewed papers have been published since the 2007 Ohsawa paper in Nature Medicine, including over 200 human studies across a wide range of physiological areas. Major nonprofit bodies such as the Molecular Hydrogen Institute maintain searchable databases of this literature.

Question 41

Where can I read the studies you reference on this site?

Accepted Answer

Our /evidence page provides an educational overview of molecular hydrogen as the output gas of Hydrogen Wellness™ inhalation systems. For the underlying literature, the Molecular Hydrogen Institute (an independent organisation, not affiliated with Hydrogen Wellness™) maintains a searchable catalogue of published H₂ research.

Question 42

Are these studies proof that hydrogen will help me?

Accepted Answer

No, and we are deliberately careful about this. Most published H₂ studies are small, early-phase, or mechanistic. They establish biological plausibility and identify promising directions, not clinical proof for any individual. We summarise the research so you can evaluate it; we do not make medical claims about outcomes.

Question 43

What are the strongest areas of published research?

Accepted Answer

The most discussed areas in the literature include biological markers studied in the published literature, exercise performance and perceived fatigue, and mitochondrial function. Most trials remain small or early-phase, which is why we describe H₂ in wellness terms rather than as a treatment.

Question 44

How do I evaluate H₂ marketing claims critically?

Accepted Answer

A few quick filters: (1) does the source distinguish ml/min (inhalation) from ppm (water)? (2) does it cite peer-reviewed papers, not blog posts? (3) does it use careful language like 'research suggests' rather than 'proven to cure'? (4) does it acknowledge that most trials are still small? Sources that pass these filters — including MHI — are the ones worth trusting.

Question 45

What does the H6 Pro™ cost?

Accepted Answer

Indicative retail is USD 5,499 per unit. Wholesale starts at USD 3,549 for a single unit, with tiered discounts at 5, 20, 50 and 100 units. The exact tier sheet is available on request — contact admin@hydrogenwellness.co. BNPL (Buy Now Pay Later) is available directly at checkout — Klarna, Afterpay and other providers depending on your country. No enquiry needed — select your preferred payment method at checkout.

Question 46

What is the minimum order quantity (MOQ)?

Accepted Answer

Single units are available for clinic and direct-consumer orders. Wholesale tier pricing begins at 5 units. Larger runs (100+) unlock the strongest unit economics.

Question 47

How does shipping work?

Accepted Answer

We ship worldwide by sea or air freight from our Asia-Pacific fulfilment hub. Sea freight is recommended for orders of 5+ units (cost-effective, 25–45 days transit depending on destination). Air freight is available for samples or urgent restocks (3–7 days). We can quote DDP (delivered duty paid) on request so you receive a single landed-cost figure.

Question 48

Do you handle CE / FDA / regulatory documentation?

Accepted Answer

The H6 Pro™ ships with CE conformity documentation suitable for wellness-device import into most EU markets. We can supply test reports and the technical file on request. FDA and other market-specific registrations are the importer's responsibility — we will support documentation but cannot guarantee a specific regulatory classification in your jurisdiction.

Question 49

What after-sales support is available?

Accepted Answer

12-month manufacturer warranty, spare-parts stock for the electrolysis stack and pumps, remote diagnostic support over video call, and training materials for clinic staff. For larger distributor agreements we can ship spares with the initial container and provide co-branded training resources.

Question 50

Can I become a distributor in my country?

Accepted Answer

We are actively appointing exclusive and non-exclusive distributors. Exclusivity is granted against an annual unit commitment and a marketing plan. Reach out via admin@hydrogenwellness.co with your market, target channel (clinics, spas, e-commerce, retail) and projected first-year volume.
