UV-C disinfection

What is UV?

UltraViolet light is part of the electromagnetic spectrum. We are exposed to it every time we walk into the sun. It can be divided into different types.

UV-A, UV-B, and UV-C are all part of the ultraviolet light spectrum.

UV-A results in skin tanning and is used in medicine to treat certain skin disorders.

UV-B has a very high penetrating ability and results in sunburn. Prolonged exposure is responsible for some types of skin disease, skin ageing and cataracts.

UV-C has extremely low penetrating ability and is nearly completely absorbed by the outer, dead layer of skin where it does little harm.

UV Technology makes use of the bactericidal effect of UV-C light in the form of UV-C disinfection.


What is UV-C?

Ultraviolet light in the C spectrum (UV-C) is energy-rich light with a wavelength of 200 – 280 nanometres (nm).

UV-C light is very versatile and can be used for disinfecting water, destroying harmful micro-organisms in other liquids, on surfaces, on food products and in ‘air’.

With UV-C technology it is possible to destroy more than 99.99% of all pathogens within seconds, without addition of chemicals, without harmful side effects, inexpensively, highly efficiently and absolutely reliably.

What Is UV-C Disinfection?

The effectiveness of using UV-C light to inactivate viruses, bacteria and other micro-organisms is not new information but with the global prevalence of
Covid-19, UV-C technology is now more important than ever.


UV-C radiation is a known disinfectant for air, water and surfaces that can help mitigate the risk of acquiring an infection and has been used extensively for more than 40 years.

All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection. In laboratory testing, Signify’s UV-C light sources reduced SARS-CoV-2 virus infectivity on a surface to below detectable levels in as few as 9 seconds. A clear indication that UV-C light can play a valuable part in your protection strategy.

The coronavirus which causes Covid-19, is known to spread via microscopic droplets. These droplets can contaminate surfaces and objects, and the air in poorly ventilated spaces creating even more opportunity for the virus to spread. 

Testing undertaken by our partner, Signify, and Boston University, has validated the effectiveness of using UV-C light to completely inactivate the virus. This has given the green light for the technology to be used as a tool to help limit the spread of Covid-19 in a multitude of settings including: offices, schools and universities, healthcare facilities and hospitality venues. 

With products available for the decontamination of air, surfaces and liquids, UV Pure are specialists in providing UV-C solutions for businesses, large and small.
