    It depends on the entire installation.

    If the room is perfectly sealed then no fan will work as it's just fighting pressure in the entire room.

    Similar if the ducting is too long or small, resulting in a static pressure which the fan will pointlessly and noisily not overcome.

    possibly this one,

    depending on the volume of air you need to shift there are various models.

    But you would need a separate humidstat in the room, not inside the duct.

    I don't consider humidstats a good solution to bathroom humidity, unless it is in addition to an atommatic switch and timer, usually operated by the light switch.

    You would attach it to something to help deaden the sound, like a thick ply board with carpet underlay on both sides to prevent vibration passing to the base surface, and positioned away from a room such as a bedroom.

    I spent a long time looking for quiet inline duct fans a few years back and eventually settled on Soler & Palau. Their TD silent fans are pretty much as quiet as you can get for quite high volumetric flow. Mine is fitted just outside the bathroom, so I get a fair amount of run noise, but unlike my neighbours fans that I can hear run late at night I only hear mine because I know what to listen for.

    First time out I installed a TD-160, but when that died after 10 years i upgraded to the TD-250. Running at 1680 rpm it puts out 20dB noise and 260m^3/hr. probably overkill for my small bathroom, but it is really effective at extracting all the humidity after a bath / shower.

    The one I bought doesn’t have a humidistat, or run on timer (the one with the timer doesn’t have the slower speed) so I bought a separate run on timer that i wired in the circuit. As John D says, you could wire a humidistat inline instead though. I have had the thought of integrating the open energy monitor temperature & humidity sensors I have in the bathroom with openhab and a Shelly automation switch to control on humidity but that project is way down the list at the moment.

    I too have a TD250 above our bathroom. It's great at clearing moisture-laden air.

    I have a couple of Soler & Palau, a different model at 26dba so not as quiet. I can hear them, softly, in the room, but not when I close the bathroom doors (which, to be fair, are FD30).

    S & P are budget end and I would suggest will not be the best unit.

    I strongly disagree.
