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.

Key takeaways

  • Tubing diameter and length both affect delivered flow.
  • Humidifiers add resistance; high-output machines compensate.
  • Cannula fit changes effective delivered fraction.

Where flow is lost

A long, narrow cannula reduces delivered flow. So does a poorly seated humidifier. Quality machines measure delivered flow, not just stack output.

Frequently asked questions

Slightly, yes — but within normal cannula lengths the difference is small.

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.
