Why Molecular Hydrogen?

Research into molecular hydrogen (H2) has gained significant momentum in the wellness community. Studies suggest that hydrogen gas acts as a highly selective antioxidant — neutralising harmful free radicals such as hydroxyl radicals and nitrite anions, while preserving beneficial free radicals the body naturally uses. Additionally, hydrogen may activate the body's own antioxidant pathways (including NRF2 activation), supporting cellular vitality and overall wellness from within.

Key Features & Benefits

• Potent Antioxidant Support: H2 targets harmful free radicals, helping to reduce oxidative stress and support healthy cell function.
• Wellness & Vitality: Supports a sense of improved energy, endurance, and overall daily vitality.
• Skin & Cellular Care: Hydrogen's antioxidant properties are associated with supporting a youthful complexion and healthy cellular renewal.
• Immune System Support: May contribute to strengthening the body's natural defence mechanisms.
• Comfortable & Restful Wellbeing: Users commonly report improved sleep quality and a greater sense of calm and balance.
• Exercise Performance: Research indicates hydrogen inhalation may support endurance and faster recovery after physical activity.
• Easy Home Use: Simple, intuitive operation — just add distilled water, power on, and inhale through the included nasal cannula.

Frequently Asked Questions

Q: What is a hydrogen inhalation machine and how does it work?

A: A hydrogen inhalation machine uses a process called electrolysis to split purified water (H₂O) into molecular hydrogen (H2) and oxygen (O2). The hydrogen gas — at 99.99% purity — is then delivered via a nasal cannula for inhalation. The GY-H200/H300 produces hydrogen at a ratio of 2:1 (H2 to O2) and outputs either 200 ml/min or 300 ml/min depending on the model selected.

Q: How often and how long should I use the hydrogen inhalation machine per session?

A: Most users incorporate hydrogen inhalation sessions of 30–60 minutes into their daily wellness routine, though individual preferences vary. We recommend starting with shorter sessions and consulting your healthcare professional for personalised guidance on frequency and duration.

Q: What type of water should I use in this hydrogen generator?

A: Only use distilled or deionised water in the GY-H200/H300. Tap water or mineral water contains dissolved minerals that can damage the electrolysis membrane and reduce the purity and lifespan of the machine.

Q: Is this machine safe for home use?

A: Yes. The GY-H200/H300 is certified to CE, RoHS, and FCC standards, and is specifically designed for safe, convenient home use within an operating temperature range of 5°C–40°C. Always follow the user manual instructions for safe operation.

Q: What is the difference between the 200 ml/min and 300 ml/min models?

A: The primary difference is the hydrogen gas output rate. The 300 ml/min model (GY-H300) delivers a higher volume of hydrogen per minute, which may be preferred by users seeking a more intensive session, while the 200 ml/min model (GY-H200) is ideal for those beginning their hydrogen wellness journey or preferring a gentler flow rate.
