I love all the features of the Hilife Ultrasonic Humidifier including the sleep feature which turns the screen off! You choose your level of intensity and built-in humidistat automatically detects your room’s humidity level and adjusts the amount of mist. I keep it on 1 and it’s photographed on 2. There’s a level 3 as well. It’s powerful and a great size. I’m really, really impressed with this. I love the Hilife brand. Highly recommend!
