Ultraviolet light is part of the light spectrum that is not visible to humans; in fact humans can only see a small portion of the light spectrum. Ultraviolet (meaning ‘beyond violet”) falls in between Violet light and X-Rays.
Within the Ultraviolet range, light is classified into three wavelengths:
• UV-C, from 200 nanometers (nm) to 280 nm
• UV-B, from 280 nm to 315 nm
• UV-A, from 315 nm to 400 nm
UVGI – Ultra Violet Germicidal Irradiation
is the process of using UV-C light to destroy micro-organisims.
UVGI is not a new technology for disinfection, it has been used since the late 1880’s to kill micro organisms in hospitals, food storage and pharma plants. The 1903 Nobel Prize for Medicine was awarded to Niels Finsen in recognition of his contribution to the treatment of diseases, especially lupus vulagris with concentrated light radiation.
It was used in the 1950’s against the war on Tuberculosis. In the 1960’s concerns against microbes lessened with the introduction of new drugs (anti-biotics) and harsh cleaners. UV-C is making a comeback due to the emergence of many Super bugs which are increasing at an alarming rate. The age of antibiotics is coming to an end. Yet still, UV-C light is able to kill 99.99% of any and every Bacteria, Virus and Super Bug known with no chemicals or residue making this product a truly GREEN product.
The germicidal wavelength (within the UV-C band) that is responsible for the destruction of viruses and bacteria is 254nm (nano meters).
Germicidal UV-C light deactivates the DNA of bacteria, viruses and other pathogens destroying their ability to multiply and cause disease. Basically the UVC light scrambles the DNA inside the cell and creates a ‘cross linking’ which prevents the DNA from being unzipped for replication. In fact when the organism attempts to replicate, it dies.
From Influenza to Ebola, there is no known micro-biological resistance to the UV-C disinfectant process.
