1. A method for selectively killing or affecting an airborne-based pathogen in an airborne environment, comprising:
providing at least one radiation having at least one wavelength that is in a range of between about 190 nanometers (nm) to about 230 nm; and
preventing, with a single filter, all ultraviolet wavelengths of UVC wavelengths of the at least one radiation that are below 190 nm and above 230 nm from passing.
