OK...now that i am totally sober and not so fucked up...let me tell you what has occured and exactly what i am asking...sorry about the mix up on the question...i already have a vent fan installed...i cut a hole in my door for the air being pulled out of the box to go out and i was wanting to know if there is something i can put infront of the fan...around the hole...to make no light and/or odor to leave.....hope this clearifies up some confusion...
