Whisper is louder than you think but when it drumrum mucksmäuschenstill is ;-)

We have installed the fan in the bathroom and he does good services. The timer works wonderfully and the connection was not a problem. We reveal the Bad still further, by letting the door (after Badbesuch) are always open. Otherwise, the fans would think I still a little overwhelmed, although our bathroom is quite small.

Information on volume: Yes it is quiet. But he is not inaudible. So compared to other fans, where one has the feeling, one would run a vacuum cleaner it is really very pleasant ;-). For showering absolutely ok. But for a relaxing bath it is us still too loud and we turn it until after. So if you really something quiet and looking a bit more has the budget, should look further.
