Having fresh and healthy air is crucial for every household and the best way to achieve that is through a high-quality humidifier. Our Ultrasonic Air Home Humidifier will safely hydrate the air for up to 16 hours of continuous operation so you can breathe easily for more restful sleep. The high and low-speed settings make it easy to adjust the direction and speed to suit your comfort level. It automatically turns off when the water level is low or the water tank is removed. With ultrasonic technology, this diffuser is extremely quiet when working, allowing you to feel comfortable.
