1. An air flow system for reducing pathogens in a breathable airstream in a localized environment, the system comprising a device having:
an airstream intake for receiving a volume of untreated air located at a first position;
an airstream outlet for expelling a volume of treated air towards at least one desired location, the airstream outlet located at a second position spaced from the first position;
a flow path extending between the airstream intake and the airstream outlet;
a UV-C source optically coupled to the flow path;
an input power source operably connected to the UV-C source;
an illumination channel along the flow path having a UV-C highly reflective surface providing an optical effective power that exceeds an input power to the UV-C source; and
a pressure generator fluidly connected to the airstream intake, the pressure generator configured to impart a flow from the airstream intake to the airstream outlet, wherein the pressure generator can be at least one of a force of flow provided by a pressurized source or a force of flow provided by a fan within a housing coupled to the illumination channel,
wherein the UV-C source is disposed within the illumination channel and includes a first radius, and wherein the illumination channel is curvilinear and includes a second radius, the second radius being equal to or less than approximately 5 times the first radius of the UV-C source.
