How to Choose a safe Hydrogen Generator?

Views [356]    Published:2025-05-16 11:23:36

Choosing a safe and reliable hydrogen & oxygen generator is crucial for health and longevity. 

Here’s a structured guide to help you make an informed decision:


1. Safety Certification & Quality Assurance
  • Avoid uncertified products: Only purchase machines with third-party quality inspection reports (e.g., CE, FDA, or RoHs certifications).
  • Verify hydrogen purity: Check for a gas composition report to confirm the machine produces ≥99.9% pure hydrogen (avoid machines with ozone or harmful byproducts).
  • Leak-proof & explosion-proof design: Ensure the generator has automatic shutdown in case of overheating or pressure issues.

2. Flow Rate & Health Benefits
Different flow rates serve different health needs:
150–600 mL/min (Pure Hydrogen): Best for general wellness, anti-aging, and mild detox.
900–1800 mL/min (Hydrogen-Oxygen Mix): Supports chronic conditions (e.g., diabetes, hypertension, COPD).
3000+ mL/min (High-Flow Hydrogen-Oxygen): Used for severe respiratory diseases (e.g., COPD, lung fibrosis).

⚠️ Avoid underpowered machines—low flow may not provide therapeutic effects.


3. Machine Stability & Durability
  • Electrolyzer Material: SPE/PEM electrolysis (best for purity & stability).
          Avoid alkaline electrolyzers (risk of corrosion & unstable output).
  • Cooling System: Choose liquid cooling or active fan cooling to prevent overheating.
  • Service Life: A high-quality machine lasts 5,000+ hours before performance declines.

4. Additional Considerations
Patents & Research Backing: Brands with medical-grade certifications or university studies are more reliable.
Noise Level: A well-designed machine operates quietly (<50 dB).
After-Sales Service: Warranty (at least 1 year) and accessible customer support.

Final Recommendation
  • For general health: Choose a 300–600 mL/min pure hydrogen machine.
  • For chronic conditions: Opt for 900–1800 mL/min hydrogen-oxygen mix.
  • For severe respiratory issues: Use 3000+ mL/min hydrogen-oxygen therapy.


900ml/min hydrogen-oxygen mix - 600ml/min H2 + 300ml/min O2




1800ml/min hydrogen-oxygen mix - 600ml/min H2 + 600ml/min O2 + 600ml/min H2 



3000ml/min hydrogen-oxygen mix - 1000ml/min H2 + 1000ml/min O2 + 1000ml/min H2
