I next cut a frame out of plywood to fit into the charcoal chamber's bottom. The frame will support the screening used to contain the activated charcoal filtering medium which also allows for air flow through the charcoal. I also cut a top piece for the box and cut a window out over the filter chamber to act as an input air port. I cut some window screening and some carpenter’s cloth for added support which will be attached to the screen frame and to the underside of the unit’s top piece as input air port screening.
