Venting?

I have an 9'W X 24'L X 10'H room I want to use one 8" Vortex with a carbon filter. On the other end of the room near the floor I want to put an air intake with hepa filter. The room will be very tight. Do I need to have a fan on the intake or will the one 8" pull intake air.

If it's good and sealed you won't need a intake fan. If you want to balance the pressure some then u will want one. + I'm not sure how much the hepa would impede the flow, might require a fan to get the temps where you want them.

make the intake 2-3 times larger than the exhaust and you will be fine.
a passive intake will be easier because you want some negative air pressure. if a intake fan creates more airflow than the exhaust, the room will have positive pressure and some smell will escape out any cracks including the door when opened.

Thanks for the reply.
