Without water, this humidifier is light weight. It is very easy to carry the water tank after it is filled as there is a place to put your fingers on each side. The humidifier runs quietly. You can choose to put it on auto and choose at what humidity you want it to turn on. Or you can choose to run it all the time and and what speed (amount of steam). The back has an area where you can add essential oils, if wanted. The scent is not strong but the room smells good. If using the app, it is easy to control the humidifier. This is an easy to use and efficient humidifier.
