This is a great smart humidifier that is perfect for a good-sized room. The mist is plentiful and I like the large water reservoir--which means less filling! The controls are very simple to use and best of all it is has an "auto" function that lets you program in your desired humidity level and it will turn on or off. The device is "Smart" in that it can connect to wifi and you can control it from your phone or from helpers like Alexa. Set up of Alexa control was a breeze! Much easier than many similar devices that I tried. Finally, I like how the humidifier is pretty easy to take apart and clean--an absolute must!
