A biosafety cabinet includes one or more air filters below the work surface and a system for holding, sealing, replacing and disposing the air filters through the work access opening of the biosafety cabinet. The air filters under the work surface of the biosafety cabinet capture particulates entering the cabinet from the exterior environment and the particulates within the cabinet's work chamber. Instead of a mechanical clamp, the perimeter of the air filters are sealed using a gasket and a tape, eliminating the accumulation of the contaminants around mechanical clamps. The air filters may be accessed through the work access opening of the biosafety cabinet, packaged for disposal and removed from the biosafety cabinet without being exposed to the exterior environment. A filter cover with an adhesive surface is used to cover and lift the used, contaminated air filter within the biosafety cabinet.
