Type of Exhaust Fan
I recommend purchasing an inline exhaust fan. Inline means its installed directly into the ducting, rather than at the end of the ducting like you are used to seeing with a bathroom fan for example. An inline unit is more powerful than an overhead unit, generally due to the fact that they are bigger because they have more space to be installed.
Inline fans are also much quieter because the fan is not directly over your head but rather somewhere outside of the room. Most people can barely tell the fan is on when its running because of where its located.
I’m particularly fond of Broan inline exhaust fans. I have used Broan’s for both of my room. My first room’s exhaust fan was a Broan L1500L and the second room is a Broan L700L.
