[Personal humidifier]: Ultrasonic technology allows almost silent operation, while generating fine cold fog. The personal humidifier is very easy to operate-all functions can be controlled with one button. [Aromatherapy oil diffuser]: Made of high-quality PP material, you can directly add essential oils to the water tank of a small humidifier, which is better than a humidifier with an aroma box. [Operation time]: The cold mist humidifier contains two spray modes-continuous spray and intermittent spray. Continuous spray can last up to 4 hours, and intermittent spray can last up to 12 hours. [Easy to fill]: The top-filled portable humidifier is designed to be easy to use and does not contain a filter. You can remove the lid and use any jug to fill a 320ml jug. At the same time, this mini humidifier is also equipped with an automatic shutdownsafety function to shut down the device when the water runs out. [More Quiet]: The personal humidifier runs very quietly, which makes it a perfect choice for light sleepers, children, especially those with babies. The multi-color LED night light mode can help you fall asleep easily.
