Ultrasonic diffuser humidifier effectively breaks down water and essential oils into fine micro-particles, helping to improve air quality. It releases negative ions to support easier breathing and adds moisture to dry air, providing relief for dry cough, chapped skin, chapped lips, itchy nose or eyes, allergies, sinus discomfort, and sleep issues. Helps reduce static electricity and neutralize odors from pets or smoke. Simple one-touch operation with multiple mist modes: short press to activate continuous mist with 7-color LED lights for 3 hours, second press for intermittent mist with light for 7 hours, third press for continuous mist without light for 5 hours, and press and hold to turn off. Features a built-in water tank with 200mL capacity, reducing the need for frequent refills. The soft LED lighting creates a calming ambiance, ideal for use in cars, trucks, or small spaces.
