Frequently Asked Questions

Q: Can I use essential oils directly in this aroma diffuser humidifier?

A: Yes! This USB aroma diffuser humidifier is compatible with essential oils. Simply add a few drops of your preferred essential oil to the water tank before use to enjoy aromatherapy fragrance dispersed throughout your room along with the mist.

Q: How long does the 900mL water tank last?

A: With a spray volume of approximately 25mL × 6 times per hour, the 900mL tank provides many hours of continuous misting — enough for a full day of use on standard settings, so you only need to refill once a day.

Q: Is this humidifier safe to leave running overnight?

A: Yes. The built-in water-shortage auto-off protection automatically shuts the unit down when the water level is too low, preventing dry-running. Combined with the timer function and ultra-quiet operation (under 36dB), it is well-suited for overnight use.

Q: What power source does this USB humidifier need?

A: It runs on a standard DC 5V / 2A USB connection at ≤ 6W. You can power it from a USB wall adapter, laptop USB port, or a compatible power bank using the included Type-C USB cable.
