The inlet visor and cowl prevent large wood chips, cigarette ashes, and other debris from entering the cascade impactor. The design concept of the Marple Samplers has evolved from the information relative to the human respiratory system. The human respiratory tract is an aerodynamic classifying system for airborne particles. A sampling device can be used as a substitute of the respiratory tract as a collector of airborne particles. As such, it should reproduce to a reasonable degree the human respiratory system so that lung penetration by airborne particles can be predicted from sampling data. The sampling instrument should therefore classify the particles collected according to aerodynamic dimensions that are the true measure of lung penetration. The fraction of inhaled particles retained in the respiratory system and the site of deposition vary with the size, shape, and density and all the physical properties of the particles that constitute aerodynamic dimensional characteristic
