My inhaler is making unusual noises — is this normal?Updated a day ago

Some sounds are expected during operation:

• Soft bubbling → Normal, caused by hydrogen being generated.

• Gentle humming → Normal, from the electrolysis process.

Unusual sounds to watch for:

• Loud gurgling → Check that humidification bottles are not overfilled.

• Rattling or vibration → Ensure the machine is on a flat, stable surface.

• Persistent alarm beeps → Indicates a system error such as low water or poor water quality.

If noises continue after troubleshooting, contact support for service.
