🌙 Ultra-Quiet Sleep Mode & Auto Safety
Operates at below 36dB—quieter than a library whisper! The sleep mode turns off all lights for undisturbed rest, and it automatically shuts off when water is low, giving you peace of mind all night.
⚡ Smart Control & Customization
Use the touch panel or handy remote to set humidity levels (40%-90%), timer (1-12 hours), and mist speed (low, medium, high). The constant humidity function stops misting once your desired level is reached, saving energy and optimizing comfort.
