Certifications explained
Five marks recur on hydrogen machine documentation. Each certifies a specific engineering or manufacturing claim — none is a medical-device approval. CE and FCC apply to the finish…
Choosing a hydrogen bath machine
Spec sheets in this category vary wildly in honesty. This buyer guide gives you a structured checklist for evaluating a hydrogen bath machine before purchase — the numbers that mat…
Choosing a hydrogen machine
A clear, vendor-neutral framework for matching a hydrogen machine to your situation. Five questions answer most of the decision. 1. Inhalation, bathing, or both? 2. How many users?…
Choosing hydrogen generation technology
If you are researching hydrogen equipment for the first time, the choice of underlying electrolysis technology is one of several engineering decisions that shape the machine you en…
Cleaning procedures
A 10-minute weekly routine keeps a hydrogen machine clean. Less than that and biofilm starts in the humidifier; more isn't necessary. Power off. Drain reservoir. Rinse with distill…
Clinic setup
A clinic running multiple hydrogen sessions per day has different requirements from a home owner: duty cycle, hygiene workflow and client throughput. A HERO Inhaler Pro 3000 suppor…
Commercial spa installation
Installing a hydrogen bath system in a commercial spa requires planning beyond the device itself: electrical, ventilation, workflow and turnover. Place the unit on a stable floor w…
Comparing specifications
Comparing hydrogen machines fairly starts with normalising units and ends with weighting the columns that matter for your use case. Pick six columns: output (ml/min), purity (%), c…
Cooling systems
Cooling is the unglamorous half of hydrogen machine engineering. Without it, peak ml/min is meaningless past the first hour. PEM membranes degrade above their rated operating tempe…
Distributor resources
Distributors carry the after-sales burden. Pick suppliers whose engineering and documentation reduce that burden rather than create it. Service manuals in English. Spare parts SKU …
Electrodes
PEM electrodes carry catalyst on both sides of the membrane: platinum on the cathode side, iridium oxide on the anode side. Coating quality drives lifespan. Mineral contamination f…
Electrolysis explained
Electrolysis passes a DC current through water to break the O–H bonds. In a PEM machine, the membrane separates the two gas streams so only pure H₂ reaches the user. Water molecule…
Electrolytes in hydrogen generation
Electrolysis cells need a way to conduct ions between the electrodes. Different cell families solve this differently. This article explains the two dominant approaches — aqueous el…
Flow dynamics
Between the PEM stack and the user's nose are several metres of tubing, a humidifier, and a cannula. Each adds resistance and can lose flow. A long, narrow cannula reduces delivere…
Frequently asked beginner questions
Quick, neutral answers to the questions every first-time hydrogen machine owner asks. Unbox, place the machine on a stable, ventilated surface, fill the reservoir with distilled wa…
HERO Bath buyer's guide
Note (2026): the S69 bath chassis has been discontinued from the Hydrogen Machines range. This educational guide is retained for reference and buyer research; for current bath syst…
Home vs professional systems
Home and professional hydrogen machines share the same core PEM technology. The difference is engineered margin: duty cycle, cooling, output and serviceability. A home machine desi…
How hydrogen bath machines work
A hydrogen bath machine is a three-stage system: hydrogen generation, dissolution into water, and steady-state replenishment through a session. This article walks through each stag…
Hydrogen bath machine certifications
Most online hydrogen bath listings are uncertified. The certifications that do exist describe the hardware and the manufacturing process — they are not therapeutic registrations. T…
Hydrogen bath machine FAQ
The questions buyers ask most often before purchasing a hydrogen bath machine, consolidated in one place. Each answer links to a deeper article when relevant. The FAQs below are th…
Hydrogen bath machine maintenance
Routine maintenance on a PEM/SPE bath chassis is light, but discipline matters: source-water quality determines membrane life, and the dissolution head needs occasional cleaning to…
Hydrogen bath machine safety
A hydrogen bath machine is a residential electrical appliance operating beside a tub of water. This article covers electrical, water and operating safety, plus storage and installa…
Hydrogen bath machines explained
A hydrogen bath machine generates hydrogenated water and delivers it into a standard bathtub, with no plumbing modification. This article explains how dissolved-H₂ bathing works an…
Hydrogen bath machines: the complete guide
A hydrogen bath machine is a dedicated appliance that dissolves molecular hydrogen (H₂) into the water of a standard bathtub. This pillar guide consolidates everything Hydrogen Mac…
Hydrogen bath vs hydrogen inhalation
A hydrogen bath machine and a hydrogen inhaler share a core technology — PEM/SPE water electrolysis — but the rest of the engineering and the delivery method are completely differe…
Hydrogen bath vs hydrogen water
Hydrogen bath systems and hydrogen water bottles both produce hydrogenated water, but they solve very different engineering problems. This article compares the two and explains whe…
Hydrogen concentration explained
Hydrogen concentration is reported in different units depending on whether you're measuring gas at an outlet or dissolved H₂ in water. Inhaler purity is a fraction of the gas strea…
Hydrogen dissolution
Generating H₂ is only half the job for bath and water systems. Dissolving it into water at meaningful concentration requires bubble engineering. Surface area scales as 1/r. A nanob…
Hydrogen inhalation basics
A hydrogen inhalation machine generates molecular hydrogen on demand from pure water and delivers it to the user through a nasal cannula or face mask. This guide covers the basics …
Hydrogen purity
Reputable PEM machines deliver hydrogen with model-specific gas composition. The other 0.01% is mostly water vapour, with trace oxygen. Purity is reported as the H₂ fraction in the…
Hydrogen Tablets vs Electrolysis — What You Should Know
Hydrogen tablets and electrolysis machines both produce molecular hydrogen, but they use fundamentally different chemistry. Tablets rely on a dissolving reaction; electrolysis uses…
Hydrogen tablets vs machines
Tablets are cheap to start, expensive over time, and depend on the magnesium reaction completing in clean water. Machines are the inverse. A daily tablet user typically spends more…
Hydrogen water explained
Hydrogen water is drinking water with dissolved molecular hydrogen (H₂). This article explains where that H₂ comes from, why open glasses lose it within minutes, and how to read a …
Hydrogen water safety
Hydrogen water is water plus dissolved H₂. From a general-wellness standpoint, it is treated like any drinking water. This article does not make medical, therapeutic or disease-rel…
Inhalation vs hydrogen water
Inhalation and drinking are the two everyday ways to get H₂ into the body. They differ in concentration, predictability and routine fit. An inhaler delivers a known ml/min for the …
Installation best practices
A few minutes of thought during installation prevents most service calls. Place the machine at hand height for the user, with the cannula reaching naturally to where the user will …
Machine lifespan
A well-maintained PEM hydrogen machine typically delivers 5+ years of daily use. Wrong water and skipped maintenance are the two biggest lifespan killers. Catalyst poisoning from m…
Maintenance
Hydrogen machine maintenance is light but essential. Skipping it shortens lifespan more than running long sessions does. Most owners settle on Sunday-evening maintenance: drain old…
PEM vs SPE technology
PEM (Proton Exchange Membrane) and SPE (Solid Polymer Electrolyte) refer to the same family of perfluorosulfonic-acid membranes. Vendors use the terms interchangeably. Most consume…
Questions to ask before buying
A short, blunt question list. Answers should be specific, not aspirational. 1. Sustained output at 60 minutes? 2. Continuous run-time before throttle? 3. Purity test method? 4. CE,…
