WHAT IS GERMICIDAL ULTRAVIOLET (OR UVGI SYSTEMS)?
UV-C light is germicidal – i.e., it deactivates the DNA of bacteria, virus and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies. Ultraviolet technology is a non-chemical approach to disinfection, which makes this process simple, inexpensive and requires very low maintenance. Ultraviolet purifiers utilize germicidal lamps designed and calculated to produce a dosage of usually at least 16,000 µW-sec/cm2 or higher as per requirement.
