Indoor UV-C lights destroy coronaviruses in the air and are safe for humans, that’s the general consensus after frantic research during 2020. In addition, UVC UV light is safer for outdoor and indoor use than previous systems. UVC systems are equipped with UV germicidal light bulbs, which kill bacteria and viruses quickly, so that indoor areas can be promoted as ‘’virus free.’’
This helps us to get back to business and back to “the new normal”
A study has found that UV-C light can wipe out 99.9 percent of coronaviruses from the air. So, from this study in the U.S., they discovered one of the most common forms of infectious diseases is transmission by air. This flies in the face of earlier accepted info so the virus is not necessarily transmitted through surface contact. This is a recent realisation however we still know that the virus can exist on surfaces in cold temperatures.
Other recent studies are showing that the Virus can indeed exist for longer periods among frozen foods. https://www.express.co.uk/news/world/1326342/Coronavirus-news-survive-frozen-food-meat-fish-covid19-latest-infection-study
For everyday life however, this is a sigh of relief for those of us who need to travel around for our daily lives and when we want to visit shops and restaurants. Just be careful around frozen foods.
So What’s known about this Virus so Far?
An infected person produces tiny droplets of virus particles by coughing, sneezing and speaking, which are contagious for hours. The virus can be transmitted by contaminated hands, SOME contaminated surfaces or by inhaling virus particles in an air aerosol.
With poor ventilation of the environment, aerosols of SARS – CoV can cause respiratory diseases and death if carried in the air.
This is why it is recommended to wear masks. Masks will not give you 100% protection but can help to reduce infection and viral load.
So we now know why systems such as PathogenUK’s UV-C air sterilisation units are so beneficial to homes, offices and medical centres.
The researchers suspect that exposure to certain ultraviolet light wavelengths kills coronaviruses that remain in droplets in the air. They also examined various UV lamps to see whether their length causes damage in humans and can therefore be used continuously to disinfect pathogens in inhabited indoor spaces.
Exposure to certain types of lamps while in operation is dangerous to human health. However enclosed systems such as the ones available at PathogenUK, are suitable for indoor use. Even while people are in the room.
UVC light has been tested by the US Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH). In addition to being an important element in the fighting of SARS – CoV aerosols, seasonal coronaviruses can be killed in the air by ultraviolet (UV) light in certain spectrums.
Why Open Lamp Systems can be Dangerous
In short, this type of light can reach living cells in the human body and therefore can damage them. The lamps in some of our systems though do not damage the eyes or skin of a person because they cannot penetrate the cells of human skin, nor the cells of the lungs, liver, kidneys and other organs. So rest assured all our systems are tested and safe.
In recent studies, a coronavirus-containing aerosol flowed in front of a distant UVC lamp and a very low exposure to the lamp was sufficient to destroy it completely.
It seems that eight minutes of contact with a distant UVC light would kill the cov, but after 11 minutes the rate rises to 95 percent and after 25 minutes it is dead. Since coronaviruses, like influenza, are sensitive to widespread U-light, it is not necessary to turn off UVA lamps in public places. This can dramatically reduce the risk of transmission of the virus from person to person, especially in winter.
So again, that’s why they are so important in today’s pandemic ridden world.
How they will be Important in the Future.
So, as discussed, we now know that these UV-C air sterilisation systems are an important tool. This is not only to get your business or company up and running again. They are also useful to keep yourself and your family safe.
Now winter is fast approaching (We’re in October, 2020 as of the writing of this article), we are seeing a spike in Covid cases and UC-V air sanitising units will be something that eases our worries and works silently in the background to kill the virus we’ve all seen ruin our year.
Now technology is improving in this area, and systems are becoming safer. PathogenUK will always be at the forefront of this technology.
Recent Japanese studies also corroborate that UV-C light kills the coronavirus safely around humans.
“A study conducted by Hiroshima University researchers found that using Ultraviolet C light with a wavelength of 222 nanometers which is safer to use around humans effectively kills SARS-CoV-2 — the first research in the world to prove its efficacy against the virus that causes COVID-19.”
So, in conclusion, we can now safely say that one of the best methods of air sanitation, or sterilisation is the use of UV-C light. From studies and real world testing, UV-C light can help your home or business effectively kill the coronavirus in the air and on surfaces.
