FAQs

What gases does the system deliver?

Our system delivers a therapeutic mixture of hydrogen and oxygen in a 2:1 ratio (approximately 66% hydrogen and 33% oxygen) at a total flow of 3000 ml per minute. The hydrogen output is 2000 ml/min and the oxygen output is 1000 ml/min, with hydrogen purity up to 99.996%.

How is the gas administered?

The gas mixture is administered through a soft nasal cannula that sits just inside the nostrils. This allows the hydrogen–oxygen mixture to blend with room air as you breathe normally, without the need for a mask or mouthpiece.

Is a 20‑minute session considered a safe dose?

When used as directed, a 20‑minute session at 3000 ml/min (H₂ 2000 ml/min, O₂ 1000 ml/min) via nasal cannula is within ranges commonly used in human studies and commercial systems. The open nasal cannula design means the gas is diluted with room air, so the actual hydrogen concentration you inhale is much lower than the generator’s output concentration.

What are the main safety considerations?

The primary safety concern with hydrogen is flammability, not toxicity. Key precautions include:

  • Using the device in a well‑ventilated area

  • Keeping the system away from open flames, smoking, sparks, and high‑heat sources

  • Following all operating instructions and maintenance schedules

Our system is designed so that, when used correctly, hydrogen does not accumulate in the room to unsafe levels.

Are there any side effects?

Most people tolerate hydrogen–oxygen inhalation well. Occasionally, users may report mild symptoms such as lightheadedness, temporary warmth, or nasal dryness from the gas flow. These effects are usually brief and resolve when the session ends.

Who should not use hydrogen–oxygen inhalation?

Hydrogen–oxygen inhalation is not appropriate for everyone. People with unstable heart or lung conditions, difficulty breathing, impaired consciousness, or those unable to remove the nasal cannula on their own should only use this therapy under direct medical supervision. Pregnant individuals, children, and anyone with serious medical conditions should consult a qualified healthcare professional before use.

Is this treatment a replacement for my medications or oxygen therapy?

No. Hydrogen–oxygen inhalation is not a substitute for prescribed medications, supplemental oxygen, or other treatments recommended by your healthcare provider. Do not change or stop any medical treatment without consulting your clinician.

How often can I do a session?

Typical wellness protocols use short sessions, often 20–30 minutes, two or more times per week. The appropriate frequency can vary based on individual goals and health status, so you should discuss an exact protocol with a qualified practitioner.

Is the device FDA‑approved or cleared?

Regulatory classification for hydrogen–oxygen generators varies by country and intended use. Check with your provider or our compliance documentation to understand the regulatory status of this system in your region and for your specific application.
