  • UV is ultraviolet radiation that naturally is generated from the sun.

  • C is a type of this ultraviolet radiation.

  • UV-C can penetrate cells,  permanently damaging their structure, which includes virus, bacteria, mold, etc.

  • UV-C technology has existed for over a century and has been used in cleaning air, surfaces, water and many other applications.

  • UV-C light is manageable and its germ fighting powers have the ability to disinfect large areas efficiently.



  • UV-C is germicidal, which damages the DNA of bacteria, virus and other pathogens and destroys their ability to multiply and cause disease.

  • UV-C light attacks the nucleic acid, which stores and transmits the genetic information of the microorganisms. It prevents the DNA from being unzipped for replication, yielding the organism unable to reproduce. After being exposed to UV-C, when the organism tries to replicate, it dies.
