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.

Key takeaways

  • Inhalers: purity is reported as a percentage (typically see model documentation).
  • Bath and water: dissolved H₂ is reported in ppb or ppm.
  • 1 ppm = 1,000 ppb = 1 mg/L.

Units in context

Inhaler purity is a fraction of the gas stream. Bath system output is a concentration in liquid. These are not interchangeable numbers.

Frequently asked questions

At standard pressure and 25°C, water saturates at approximately 1.6 ppm of H₂. Higher figures require elevated pressure during dissolution.

We Build the Equipment. You Make the Decision.

This category has a real trust problem — overstated claims, high-pressure sales, machines with no independent verification behind them. We're not adding to that. We build hydrogen systems using transparent construction and natural materials. Consult each product's specifications and supporting reports for gas purity and composition. Whether hydrogen inhalation is right for you is a decision to make with your own research and your own doctor — not something we're going to try to convince you of.
