Particulate Filtration Design Considerations for Crewed Spacecraft Life Support Systems

Particulate filtration is a key component of crewed spacecraft cabin ventilation and life support system (LSS) architectures. The various particulate filtration needs in an exploration vehicle LSS architecture are presented. Particulate filtration concepts are reviewed and design considerations are discussed. Testing results for media filter concepts are presented. Observations from these results that emphasize key design considerations for integrating particulate filtration into an LSS architecture are discussed. A recommended particulate filtration architecture based on testing results and best practice design considerations is proposed.
