I am tired of having dust everywhere.
If you don't mind the hum of fans, it's hard to beat a Corsi-Rosenthal box... there are kits from cleanairkits.com or cybernightmarket.com to build quiet PC fan based boxes that in my experience work excellent and can use off-the shelf filters and parts
It works in many other industries like UL for electronics, Intertek, NSF for foods etc.
