You might need to read then... see the link in my signature about fans. There is a bit about filters in there. It's pretty simple. The fan pulls (or pushes in some cases) the air through the filter which removes the organic material. Hence it scrubs the air before exiting the grow area. You vent the room and eliminate the odor in one shot.
