Apparatus, method, and system for selectively effecting and/or killing bacteria

An apparatus for generating at least one bactericidal radiation to kill an airborne-based pathogen in an airborne environment, comprising:

• an ultraviolet (UV) source configured to generate the at least one radiation that kills the pathogen in the airborne environment, wherein the at least one radiation has a peak wavelength provided in a range of approximately at 190 nanometers (nm) to approximately at 230 nm;
• and
• at least one filter arrangement which includes at least one of:
• (i) a bandpass filter,
• (ii) a combination of a low pass filter and a high pass filter, or
• (iii) a longpass filter,
• wherein the at least one filter arrangement is configured to (i) prevent all UV wavelengths of the at least one generated bactericidal radiation that are outside of the range of approximately at 190 nm to approximately at 230 nm from passing through the at least one filter arrangement, and (ii) allow wavelengths in the range of approximately at 190 nm to approximately at 230 nm to pass through the at least one filter arrangement.
