Is it possible to seal the room completely? Filtering the air coming into the room doesn't seem like it would make much difference if the odor is still able to escape the room. If it's not possible to seal the room entirely, you may eventually want to think about using an exhaust with a slightly higher cfm rating.

Or you could look into masking the smell, which is a cheaper alternative, but may add an unwanted scent to your buds. Or take away the scent altogether.
