    Really depends on how much heat will be put in the room - what lighting etc?

    General rule is to go as big as you can fit and afford and then fan control.

    Id say minimum of 6" exhaust but would go for at least 8"

    Filter again go for a quality one and as big as you can afford/fit

    If you are going to use speed control for your inline fans, you have to use an expensive controller since cheap ones makes fans sound even louder when slowed down
