We have a Timberk THU UL 11 W humidifier, laconic design, it looks rustic on one side, but it fits perfectly into our interior.
The reservoir in the humidifier is 4 liters of water, I try to pour only filtered water, otherwise everything inside the device becomes plaque. But to be honest, then with filtered water, the insides are covered with a coating, but not at such a fast pace.
A full tank lasts up to 17 hours at full power, I think this is an excellent indicator. For example, if I install a lower power, then a humidifier is enough for almost a day.
There are ionization functions, when I turn it on, I don’t see much difference in work. Also, there is a charcoal filter, quite convenient to use, it is not necessary to change it by the way, so often. It’s inconvenient to look after him, but it's all the little things, you can get used to it.
pros
humidifies the air in one room, several atomization power levels, touch control panel, there is ionization, it works 15-17 hours, there is a timer, the function of warm steam
Minuses
the design is inconvenient for caring for the device, there is a white coating on furniture and windows, the fan began to make noise after 7 months of operation
