1. A workstation for microgravity environments, comprising:
a downdraft table, comprising:
a plenum chamber having an inlet and an outlet;
a fan disposed in the plenum chamber, wherein the fan is configured to draw air into the plenum chamber via the inlet and to exhaust air from the plenum chamber via the outlet;
a grate disposed across the inlet; and
an air resistive stack disposed on an outer side of the grate, wherein the air resistive stack comprises:
a first resistive layer disposed on the grate; and
a second resistive layer disposed on the first resistive layer, wherein the second resistive layer is configured for rolling such that the second resistive layer may be rolled up and discarded while the first resistive layer partially maintains a pressure differential in the plenum chamber.
