A novel and versatile vertical ventilation diffuser system to reduce transmission of airborne particles provides an harmful airborne particle nearly free indoor environment for one or multiple person to breathe, and to isolate and protect the personal space of a person by means of reducing the horizontal flow of air inside an enclosed space and transporting any possible harmful airborne particles, such as viruses, by means of a top down air flow. Thereby, a continuously clean environment is maintained by generating an air curtain around each person by means of a vertical ventilation diffuser system, which may be custom designed and sized for multiple types of suspended ceilings, or in standard sizes, with particular application in office, school, restaurant or concert hall settings. The versatile vertical ventilation diffuser system may further be implemented in a matrix configuration to promote the use of multiple users in a single indoor space.

A system that screens for particularly identified odors, such as those associated with explosive and other bomb-making materials, weapons and illegal drugs, includes an odor delivery unit with one or more fans that force air across the object being screened, such as a person. The airflow from the odor delivery unit passes over and across the object being screened creating an odor stream that passes through a partition that allows the odor stream to flow freely through it and simultaneously obscures a canine positioned on the other side of the partition from view by the person or object being screened.
