Ultrasonic Humidifier - 3.5L Large Capacity - Integrated Design! The tank and base are designed as one unit to prevent water leakage. Equipped with a 3.5L large-capacity tank, it's perfect for bedrooms and living rooms at home, as well as large office spaces. (Note: Be careful not to overfill past the MAX line, as this may reduce or stop mist production. Also, be careful not to invert the energy-collecting ring's top and bottom positions.) UV Light Sterilization & Aroma Compatible Humidifier The UV light has an antibacterial function; pressing the UV button turns on the light, eliminating 99% of bacteria in the water. This humidifier can release clean mist. It also supports water-soluble aroma oils; adding your favorite aroma oil to the tank will spread a pleasant fragrance throughout the room. (Note: If using hypochlorous acid water, dilute it. A concentration of 50ppm or less is recommended.) Dual Outlets, 360° Rotating Outlets, Top-Fill Design Equipped with dual nozzles that can be manually rotated 360°. This prevents excessive humidification in one area. The top-fill design allows you to add water directly by opening the lid. (Note: Do not exceed the maximum water level, which is the height of the central conduit.)
