Help...have read in the past the exhaust fans in bathrooms generally
aren't
that effective. In other words, by simply ensuring the door is left open
after a shower, as much humidity can be removed from the room as an
exhaust
fan could.

I live in Northeastern Wisconsin. Opening a window is not a year round
solution. Am concerned with the efficiency (or lack of) an exhaust fan
during the winter months. I also have a teenaged daughter that believes
it's necessary to blow dry her hair for 20 minutes after her shower. So
not
only is the room a bit on the humid side, it gets heated by the dryer.

Would appreciate any thoughts/comments on the subject.

Bathfans are required if there is no window where I live.

Installing one that is sized properly is one of the keys. I just put in a
100 cfm fan in a 4X10 room.
It has trouble with the whirlpool tub.
Installing a fan will cause you to loose some heat in the winter. Can not be
helped. Even if you do not run the fan long.

Getting rid of humidity is an issue for me. I prefer it dryer to wetter.
