Good product, but pay attention to the size of the room to be humidified.

Getting easy walk, just follow the few steps in very clear instructions. The water tank is actually very easy to fill and clean. The filter is easily accessible, the procedure for washing or replacement is very simple and very well explained. Question ergonomics, it can not be clearer: a button that we turn to choose Speed ​​2 Speed ​​1 or off. Speed ​​2 is a bit noisy, but bearable. The only real complaint I can make is that the box and the description is not clear that this device is designed for a room of about 25m2. In a room of 40 m2, after 8 hours of operation at maximum speed, the humidity is increased from 39 to 42%. It's not bad, but it's still little. In summary, a good product, very easy to use and maintenance, but it will be really effective in a room of 25 m2 or smaller.
