This fume hood box design is perfect for adding more filters at the top; just stack up what you need! Go for 4″-thick, pleated filters with a coarse filter first, on the bottom, and then a finer filter on top. You can add more carbon filters at the top if you make ductwork to connect them together.
Laboratory Fume Hoods Laboratory Fume Control Sentry Air Systems
A fume hood is a ventilated enclosure in which gases, vapors and fumes are captured and removed from the work area. An exhaust fan situated on the top of the laboratory building pulls air and airborne contaminants through connected ductwork and exhausts them to the atmosphere. The typical fume hood found in Princeton University laboratories is.
