venting ?

Im planning on pulling air from my attic and exhausting back into the attic. would it work to have an inline fan on the intake side end running duct to my air cooled hood taking the glass out to pull hot dirty air in through the hood from the room and exhausting back into the attic with a carbon filter on end of the duct in the attic, I have twointakes at the bottom of my 8x3x8 room on opposite ends. I hope Im explaining my plans clearly. any help would be valued

Exaust'n your heat into your attic will be fine, but you donot what to recirculate the same air. Pull your air from anywhere BUT your attic. Pulling air from your attic in a big NO, NO! You want cool air coming in.

so I don't pull from the attic, my bottom intakes are fine for fresh air. just pull "dirty" air through the filter. thanks,
