Far-UVC Light: The Safe and Effective Solution for Killing Airborne Coronaviriruses
The COVID-19 pandemic has brought the world to a standstill and has raised concerns about the transmission of the virus through the air. With the virus spreading through airborne droplets, researchers are exploring new ways to kill the virus in indoor spaces. Far-UVC light has been found to be a safe and effective solution for killing airborne coronaviruses.
What is Far-UVC Light?
Far-UVC light is a specific wavelength of ultraviolet light that has a short enough wavelength to kill airborne viruses like coronaviruses and influenza, but it is safe for use around humans. Unlike conventional germicidal UVC light, far-UVC light cannot penetrate the tear layer of the eye or the outer dead-cell layer of skin, making it safe for use in occupied indoor spaces.
The Study on Far-UVC Light
A recent study conducted by researchers at the Vagelos College of Physicians and Surgeons at Columbia University Irving Medical Center showed that more than 99.9% of airborne coronaviruses were killed when exposed to far-UVC light. In the study, the researchers used a misting device to aerosolize two common coronaviruses and then flowed the aerosols through the air in front of a far-UVC lamp. After exposure to the far-UVC light, the researchers found that more than 99.9% of the exposed virus had been killed.
How Far-UVC Light Works
Far-UVC light works by penetrating the virus’s outer layer and damaging its genetic material, making it unable to replicate and spread. The sensitivity of coronaviruses to far-UVC light suggests that it may be feasible and safe to use overhead far-UVC lamps in occupied indoor public places to reduce the risk of person-to-person transmission of coronaviruses and other viruses like influenza.
Using Far-UVC Light in Occupied Indoor Spaces
The results of the study indicate that it would take just 8 minutes of continuous exposure to far-UVC light at the current regulatory limit to kill 90% of airborne viruses, and 99.9% of the viruses would be killed in 25 minutes. This suggests that far-UVC light could be used in combination with other measures like wearing face masks and washing hands to limit the transmission of SARS-CoV-2 and other viruses in indoor spaces.
Ongoing Studies on SARS-CoV-2
In a separate ongoing study, researchers are testing the efficacy of far-UVC light against airborne SARS-CoV-2, and preliminary data suggests that far-UVC light is just as effective at killing SARS-CoV-2 as it is with other coronaviruses. Far-UVC light doesn’t discriminate between different types of coronaviruses, making it a powerful tool in the fight against the COVID-19 pandemic.
The Potential Benefits of Far-UVC Light
Far-UVC light has the potential to be a game-changer in the fight against the COVID-19 pandemic and other airborne viruses. It is safe to use in occupied spaces like hospitals, schools, restaurants, offices, theaters, and any indoor spaces where people gather, making it a versatile tool for killing airborne viruses.
The Future of Far-UVC Light
The study on far-UVC light has shown promising results in the fight against airborne coronaviruses, and ongoing studies on SARS-CoV-2 are expected to provide even more insights into the potential of this technology. With the COVID-19 pandemic still ongoing, the demand for effective and safe solutions for killing airborne viruses is only increasing. Far-UVC light has the potential to play a critical role in preventing the spread of viruses in indoor spaces, making it a crucial technology for public health and safety.
