Frequently Asked Questions
Q: How does the top-fill design of this cool mist humidifier work?

Q: How long can this humidifier run on a full tank?
A: On a full 4.5L tank, the humidifier runs for approximately 15 hours at normal mist output, making it ideal for overnight use in a bedroom or an all-day run in a home office or plant room.
Q: Is this humidifier suitable for use near indoor plants?
A: Yes! The 360° rotatable nozzle lets you direct cool mist toward your plants with precision, and the consistent moisture output of 300ml/h helps maintain the humidity levels many houseplants love.
Q: How quiet is the sleep mode on this humidifier?
A: The humidifier operates at under 36dB in sleep mode — quieter than a whisper — so it won't disturb light sleepers, babies, or anyone working in a quiet environment.
