I'm looking for some kind of material/filter to put over my passive intake. It must prevent light from getting in, and prevent smells from getting out, and it should not restrict airflow to any great extent.
Ideas?
PS: Butterfly dampers are out of the question because of the clanging noises. They also restrict airflow much more than most would think.
