Dry, stale air can leave you feeling itchy and irritable. Utilizing high-frequency sound to vaporize mist, the BONECO Ultrasonic Humidifier moisturizes your air for a calmer, more pleasant environment. Producing both cool and warm mist, the humidifier ensures your air feels better than ever, improving sleep and the health of your sinuses. Ultrasonic vibrations turn liquid water into a vapor that is then circulated around your room with the built-in fan, helping you achieve healthier skin and hair. Humidifying at up to 4 gallons per day, the appliance moisturizes the air in the largest rooms up to 1,000 square feet in area. A 2-in-1 water filter creates pure humidification without leaving residue on the machine, and you can clean the parts by hand for easy maintenance. Designed for simple operation, a low-level light indicates when the system is low on water, and the auto-shutoff feature turns the device off once the water reservoir is empty. This humidifier comes equipped with a smart digital display, featuring automatic dimming technology and an ambient LED night light. Perfect for keeping your home free of static and dryness, the Ultrasonic Humidifier from BONECO ensures your atmosphere is calm and comfortable all year long.
