HOW DOES UVGI WORK?
UVGI works as a mutagen to bacteria, viruses and other microorganisms on a cellular level, penetrating the cell wall. This disrupts the microorganism DNA (deoxyrilbonucleic acid), breaking the carbon bond, which causes the death of the cell and/or renders it incapable of multiplying. UV has been known as a mutagen for over a hundred years. In 1903 the Nobel Prize for Medicine was awarded to Niels Finsen for his use of UV against tuberculosis.
Simple installation and ease of operation, together with the cost and environmental benefits over other processes, makes UV air sterilisation a viable technology option for indoor air purification. However, its success depends on the UV intensity combined with ‘dwell time’ - the length of time particles are exposed to the light.
