What is UV light?
Ultraviolet (UV) light is a form of light, invisible to the human eye, that exists on the electromagnetic spectrum between X-rays and visible light. UV light includes the sub-spectrums of UVA, UVB, UVC, UVV
UVC for disinfection
UVC sub-spectrum wavelengths are between 200 and 300 nanometers and they are germicidal – meaning they are capable of inactivating microorganisms, such as bacteria, viruses and protozoa. This quality makes UVC light an effective, environmentally-friendly and chemical-free way to de-activate microorganisms and viruses in any environment!
UVC for disinfection has many years of proven use in hospitals and healthcare units
and many studies demonstrating its unique efficacy
How does UVC destroy microorganisms and viruses
By breaking their DNA!
The high energy from short wavelength UVC light is absorbed in the cellular RNA and DNA, damaging nucleic acids and preventing microorganisms from infecting and also reproducing
UVC is the only germicidal UV spectrum
There are three UV light wavelength categories: UVA, UVB and UVC.
UVC is the only wavelength known to be germicidal. UVC utilizes short-wavelength ultraviolet radiation (shorter than UVB and UVA, which are NOT germicidal) that is harmful to microorganisms and viruses
Due to high efficacy, UVC needs to operate in empty rooms to avoid skin / eye irritation
UVC effectiveness
Efficacy depends mainly on the following:
- Power output of the UVC device
- Distance from surfaces
- Duration of emission (exposure)
- Type of micro-organisms / viruses targeted
Efficacy in deactivating bacteria, viruses etc., is up to 99% or more depending to the parameters above
Key benefits of UVC technology for disinfection
- No chemicals / Environmentally-friendly
- Affordable, touchless and fast
- Microbial cells cannot develop resistance to this technology
- Proven ability to be able to deploy it safely to kill bacteria, mould, fungi, and viruses
