The unit comes well packaged and can be taken in 5 minutes in operation. If the device was placed, it is recommended to wait 1 hour. The fan on low is not annoying, on high, it is a little uncomfortable. Therefore, the device in relation to the volume should always be a little buy oversized. It is advisable to use a timer, so you can the device z. B. after the shower yet run 2 hours, and then it turns off. The water tank is large in size.
I highly recommend it. Our bathroom has a volume of about 22 m3 and it is the device perfectly adequate.
