About This Product 💧 Smart Humidity Guardian: This 4-liter cool mist humidifier features a real-time humidity sensor (adjustable from 45-90%) that automatically maintains the ideal humidity level for delicate skin, houseplants, and wooden furniture. 12-hour continuous operation and automatic shut-off prevent over-humidification. 🌙 Quiet: An ultra-low 28dB sleep mode eliminates dry throats and nasal congestion without disrupting sleep, making it ideal for light sleepers and shift workers. 🔄 3-Second Filling System: The wide-mouth design (22cm diameter) allows you to fill directly from any kettle, even during operation. The detachable mist hose and anti-scaling coating reduce cleaning time by 70% compared to traditional bottom-fill models, essential for busy households. 🔋 Dual Control Convenience: Includes a remote control (5m range) and a touchscreen with a dimmable nightlight.
