The Center for Radiological Research at Columbia University Irving Medical Center (CUIMC) discovered a new, low-cost solution to killing airborne viruses in indoor spaces.
They found that continuous low doses of far ultraviolet C (far-UVC) light kills airborne flu viruses without harming human tissues.
Routinely used to decontaminate surgical equipment, scientists have known for decades that broad-spectrum UVC light, also called germicidal ultraviolet, with its wavelength of 200 to 400 nanometers (nm), kills bacteria and viruses by destroying the molecular bonds holding their DNA.
Germicidal ultraviolet light, typically at 254 nm, is effective but if used directly, is dangerous to the skin and eyes.
UV light falls into UVA, UVB and UVC.
It’s UVC, which has the shortest wavelength and the highest energy, that is the disinfectant.
Far-UVC light at 207–222 nm kills pathogens without harm to human tissues because it has a “very limited range.”
Bacteria and viruses are smaller than human cells, thus, far-UVC reaches and kills their DNA.
Researchers note that the use of “far-UVC light in indoor public locations” is “a promising tool” in reducing “the spread of airborne-mediated microbial diseases.”
So, since ultraviolet light has been used to kill pathogens, does it work against SARS-CoV-2, the virus behind the current pandemic?
UVC light destroys bacteria and pathogens’ ability to multiply and thereby cause disease.
When UVC light gets used, the moment bacteria, viruses and other pathogens try to replicate, they die.
The safe ultraviolet technology of Cleen UV, far-UVC, is a non-chemical way to disinfect while indoors, on-the-go or outdoors.
Nothing gets added in Cleen UV’s products’ disinfecting ability making the process not only simple but also very inexpensive.
During these COVID-19 times, when the global death toll of COVID-19 passes the one million mark, where can the power of UVC light, in different disinfecting products from Cleen UV get used?
Cleen UV’s disinfecting technology can get used for drinking and bathing water, food processing, medical and manufacturing industries.
Cleen UV’s UVC products are chemical-free and portable so that homes and business establishments can harness the power of far-UVC and protect themselves from COVID-19.
The power of light. The power of UVC. The power of Cleen UV.
