Ultra-violet (UV) light provides high-energy germicidal solutions against mold, bacteria, viruses and other microbial growth. The use of UV light as a germicidal application within a building’s HVAC system has been an accepted solution and growing in popularity over the past couple decades. The same technology can be used to disinfect hospital/patient rooms and personal protective equipment, however there are many unknown factors centered around COVID-19 and that leaves many people uncertain about the effectiveness of UV light as a disinfectant. In today’s post we’re going to share the science behind this technology.
What is Ultra-violet?
Ultra-violet light is one form of electromagnetic energy produced naturally by the sun. UV is a spectrum of light just below the visible light and it is split into four distinct spectral areas – Vacuum UV or UVV (100 to 200 nm), UVC (200 to 280 nm), UVB (280 to 315 nm) and UVA (315 to 400 nm).
The entire UV spectrum can kill or inactivate many microorganism species, preventing them from replicating. UVC energy at 253.7 nanometers provides the most germicidal effect. The application of UVC energy to inactivate microorganisms is also known as Germicidal Irradiation or UVGI.
UV-C exposure inactivates microbial organisms such as bacteria and viruses by altering the structure and the molecular bonds of their DNA (Deoxyribonucleic acid). DNA is a “blue print” these organisms use to develop, function and reproduce. By destroying the organism’s ability to reproduce, it becomes harmless since it cannot colonize. After UV-C exposure, the organism dies off leaving no offspring, and the population of the microorganism diminishes rapidly.
Ultra-violet germicidal lamps provide a much more powerful and concentrated effect of ultraviolet energy than can be found naturally. Germicidal UV provides a highly effective method of destroying microorganisms.
