Bioaerosol sampling and characterization is a challenge in industrial hygiene, both in the civilian realm and for the Air Force. This literature and technology review reports several bioaerosol collection technologies that are currently commercially available and possibly modifiable or in development. Fifteen commercially available options were evaluated by a set of selection criteria to provide a comprehensive comparison and recommendation. Technologies under development were not scored in the same manner but were appraised for future utility. The selection criteria were based on parameters such as size ranges of bioaerosols that could be collected, biological agent survivability, collection time, collection quantity, collection efficiency, sampling flow rates, device portability and device ruggedness. Technologies were selected based on criteria required to be effective samplers in real-world AF-relevant environments where space is limited and personal sampling is desirable. Technologies were down-selected based on the criteria evaluation. There were six commercial off-the-shelf technologies down-selected, including a high volume cyclone impinger Coriolis Recon, Bertin Instruments, a handheld high volume rotating impactor BioCapture 650, FLIR Systems, a two-stage high volume impactor SASS 4100, Research International, a compact high volume dry cyclone sampler Coriolis Compact, Bertin Instruments, a high-volume membrane filter impaction device MD8 AirPort Sampler, Sartorius, and a cassette filter with sampling pump available from various manufacturers. There were two technologies under development that are recommended for further investigation, including a personal electrostatic bioaerosol sampler PEBS and the Rutgers Electrostatic Passive sampler REPS. All recommended samplers have advantages and disadvantages and require further experimental validation for use in specific AF applications.
