Up to 2,400 mL (approx. 81 oz) per 8-hour session.

Does the machine alert when water is low?

Yes, it will notify you when water needs refilling.

Can I hydrogenate drinking water with the machine?

Yes. Suggested times:

• 8–12 oz glass: 2–3 minutes
• 32 oz: approx. 10 minutes
• 1 gallon: 10–15 minutes

When is the best time to drink hydrogen water?

Any time of day works. Some prefer 2–4 oz on an empty stomach in the morning, but it’s beneficial throughout the day.

How long does hydrogen water stay active?

• Open glass: 15–30 minutes
• Sealed mason jar: 1–2 hours (or longer if chilled and sealed)

How do I clean the machine’s interior?

• Fill the tank with distilled water and drain completely.
• Do not use any cleaning chemicals.
• Never pour anything other than distilled water into the machine.

What maintenance is required?

Weekly:

• Replace water weekly (or after 7 days unused)
• Clean cannulas and tubing with rubbing alcohol, rinse with hot water

Monthly:

• Drain and clean tank with distilled water if E002 error appears

How often should I replace hoses?

• Every 3 months, or sooner if discolored or damaged
• Clean nasal ends with alcohol swabs between uses

3. Drain and refill

Can I adjust the timer to less than 30 minutes?

No. The machine operates in preset 30-minute increments.
➡️ You can manually turn it off earlier if desired.

Does the machine require a warm-up?

No. Hydrogen and oxygen begin flowing within seconds of startup.

Does the machine always run for 30 minutes?

Yes, that’s the default setting. It’s not a malfunction.

Should I turn the machine off between uses?

Yes, especially for energy savings and safety during long breaks. Otherwise, it’s safe to leave plugged in.

🌬️ Inhalation & Therapy Guidance

Is it better to inhale on an empty stomach?

No. Since hydrogen is inhaled through the lungs, stomach contents do not affect the process.

When should I use hydrogen only vs. hydrogen + oxygen?

Can I use accessories like an eye mask or earphones?

The machine supports two accessories simultaneously, but we recommend using one at a time for better results and comfort.

What kind of tubing is required?

• Must use 3-channel tubing (for dual gas delivery)
• Third-party tubing may work but is not guaranteed to be safe or compatible

Can I use longer tubing (e.g., 14 ft)?

Yes. Longer tubing is compatible, but may slightly reduce gas flow rate.

Are face masks compatible?

Yes, but not included. Must be compatible with 3-channel tubing.

Do I need to keep the rubber side plugs in when not in use?

When in use, both caps should be open.
When not in use, you can leave them open or closed, your choice.

What does the E002 error mean?

Triggered when water needs to be drained and cleaned.
➡️ Follow monthly maintenance: clean with distilled water.

What does the E008 error mean?

Happens when oxygen cap is closed while machine is running.
