UVC Cleaning

UVC as a surface disinfectant

UVC light has has been proven to effectively kill all known pathogenic bacteria, fungi and viruses including the COVID-19 virus, SARS-Cov-2.

What is UVC Light?

We are all familiar with UV light generally – it is what gives us sunburn if we stay out in the sun too long. However UV light is divided into UVA, UVB and UVC, each being a different band of wavelength of light in the non-visible spectrum. UVC doesn’t exist naturally in the earth’s atmosphere as it is absorbed well before it reaches us. Because UVC doesn’t occur naturally on the earth’s surface, common pathogens that prove dangerous or deadly to humans have no natural defence from it. Since UVC can be artificially created, it has been used for decades as a very effective decontamination agent against these pathogens.

The effectiveness of UVC depends on a number of factors, most importantly a) The wavelength of UVC light used b) The intensity of the light source c) The distance of the light source from the surface to be decontaminated d) The duration of exposure e) The substance being decontaminated (metal, cloth, wood, plastic etc).

Radiation energy and light

When, where and how does UVC disinfect?

UVC radiation (typically with a wavelength of 254nm, but more broadly in the 250nm to 280nm range) disrupts the organism’s DNA in a way that prevents cell replication. Without the ability to reproduce, they die. The ability of UVC to cause this depends on the total irradiation level, which is a combination of light intensity, and distance from the light source.

It is important to recognise that the primary transmission mechanism for viruses such as Covid-19 is touch, so to be effective all surface areas of a shared device (headset, laptop, keyboard etc) which may be touched need to be fully disinfected.

A well-designed UVC cabinet, such as the Uvisan cabinet, ensures that an even coverage of the right level of UVC reaches all areas of the cabinet, so that ALL surfaces are disinfected. This is why simple solutions such as UVC wands, or other boxes that only irradiate one part of the device (eg. the inside of a headset) are not fit for purpose as the user cannot ensure consistent irradiation of all surface areas at the required intensity.

Common Question

Why is UVC cleaning better than using anti-bacterial wipes?

More reliable and consistent results

Wipes require manual application to all surface areas and rely on users being thorough and uniform in their use every time. Uvisan’s patented cabinet design ensures complete cleaning coverage of at-risk surface areas for reliable and consistent results.

Not harmful to devices

Over time the alcohol in wipes will damage devices, particularly optical lenses and soft padded areas. Uvisan’s UVC technology has been tested exhaustively and will not damage even the most sensitive of devices and surfaces.

Time efficient and cost effective

To be fully effective, devices cleaned with single-use wipes must be left wet on all surfaces for five minutes and allowed to dry naturally. Uvisan cabinets operate on a fast two minute cycle time with no waste, saving you both time and money, as well as ensuring you get maximum life from your devices.

Better for the environment

Though many disposable wipes are marketed as “flushable” they often contain plastic and are not biodegradable, leaching into soils and finding their way into the underground water table and oceans. Along with other types of plastic pollution, they can cause long-term problems. Uvisan cabinets eliminate harmful environmental impact.
