Abstract
Certain exemplary embodiments can provide an apparatus and method for generating at least one radiation. The exemplary apparatus and/or method can selectively kill and/or affect at least one bacteria. For example, a radiation source first arrangement can be provided which is configured to generate at least one radiation having one or more wavelengths provided in a range of about 190 nanometers (nm) to about 230 nm, and at least one second arrangement can be provided which is configured to prevent the at least one radiation from having any wavelength that is outside of the range.
Claims21
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.
An apparatus for generating at least one radiation to kill or damage an airborne-based pathogen in an airborne environment, comprising:
- at least one device configured to:
- (i) provide the at least one radiation having one or more wavelengths that is in a range of about 190 nanometers (nm) to about 230 nm, and
- (ii) prevent all ultraviolet wavelengths of UVC wavelength range of the at least one radiation that are below 190 nm and above 230 nm from passing using a single filter of the at least one device.
