UV-C light destroys the DNA of biological pollutants and other pathogens and eliminates their ability to multiply. Specifically, UV-C light damages the nucleic acid of micro- organisms by forming bonds between certain adjacent base pairs in the DNA. The formation of these bonds prevents the DNA from being “unzipped” for replication and the organism is then unable to reproduce. When the cellular organism attempts to replicate under these conditions, it dies in the process. In the case of single-celled organisms, the result is almost immediate. With more complex organisms like dust mites, the process is more involved but equally effective.
