One of the most exciting and promising solutions is Far-UVC light.

With nearly 800 million confirmed cases (according to the World Health Organization) since the pandemic began, COVID-19 has profoundly impacted every corner of the globe, reshaping the way we live, work, and interact with one another. While we cannot predict if or when another pandemic will occur, we can be proactive and prepared.

The pandemic has changed the landscape of research, technology, and healthcare, ushering in a wave of innovative solutions to help prepare to combat a viral pandemic when it occurs. One of the most exciting and promising solutions if Far-UVC light. In this blog, we will explore why Far-UVC light is a leader in pandemic preparedness, its benefits, and its potential applications to safeguard public health.

Understanding UV-C light

In our previous blog, we discussed the ins and outs of Far-UVC light at length, but here’s a quick summary:

What is Far-UVC light?

Far-UVC light refers to ultraviolet C (UVC) radiation with a wavelength between 207 and 222 nanometers (nm). Unlike conventional UVC light, which is known for its germicidal properties but is harmful to human skin and eyes, Far-UVC light possesses unique characteristics that make it a safer and more practical option for continuous disinfection in occupied spaces.

Safe for humans

One of the key advantages of Far-UVC light is its safety for humans. Traditional UVC light, with a shorter wavelength (typically 254 nm), can cause skin cancer, eye damage, and other harmful issues if exposed to it directly. In contrast, Far-UVC light is less harmful to human tissues. It is primarily absorbed by the outermost layer of human skin, limiting its penetration and minimizing the risk of harm.

Effective at killing microorganisms

Far-UVC light is highly effective at inactivating a wide range of microorganisms, including viruses, bacteria, and fungi. It damages the genetic material of these pathogens, preventing them from replicating and causing infections.

Recent research by Brenner and Batchley describes why Far-UVC light is especially useful in targeting RNA viruses with long genomes, which is precisely what coronaviruses are. These longer chains of RNA make them more vulnerable to being damaged by UV-C exposure.

Furthermore, studies have demonstrated its efficacy in reducing the spread of airborne pathogens, making it a powerful tool in preventing the transmission of infectious diseases. One study has proven Far-UVC effective at inactivating two different types of airborne coronaviruses that cause coughs and colds.

Understanding UV-C light


UVC disinfection is environmentally friendly. It does not produce harmful byproducts, and it can be integrated into a medical facility’s sustainability efforts by reducing the need for chemical disinfectants and disposable items.

Cost savings

While there is an initial investment in UVC equipment, the long-term cost savings can be significant. Fewer HAIs and SSIs mean shorter hospital stays and reduced healthcare costs for both patients and healthcare providers.


UVC technology is versatile and can be used in various healthcare settings, including hospitals, veterinarian offices, clinics, dental offices, and even ambulances. It can be applied to a wide range of surfaces and equipment, such as bed rails, doorknobs, ventilators, and surgical instruments.

Complementary to standard cleaning practices

UV-C disinfection does not replace standard cleaning practices but  complements them. UVC disinfection provides an added layer of protection against pathogens that may be missed during routine cleaning.

Far-UVC light and pandemic preparedness

Now that we understand the basics of Far-UVC light, let’s delve into why it could be an asset in pandemic preparedness.

Continuous disinfection in public spaces

Traditional disinfection methods often involve chemical agents or UV-C light that must be used in unoccupied spaces due to their potential harm to humans. Far-UVC light, being safe for human exposure, can be used continuously in occupied areas such as healthcare facilities, hospitals, schools, offices, and public transportation. This means that even during a potential pandemic, these spaces can remain safer for people, reducing the risk of transmission from person to person.

Reduced dependence on PPE

Personal Protective Equipment (PPE) has played a critical role in controlling the spread of infectious diseases. However, its supply can be limited during pandemics, and its use can be uncomfortable and costly. During the COVID-19 pandemic, medical professionals and the public alike experienced severe shortages of PPE, particularly in the earlier stages of 2020.

Far-UVC light offers an alternative approach by continuously disinfecting the air and surfaces in shared spaces. This can reduce the reliance on PPE, making it more available for frontline healthcare workers and those in high-risk environments.

Rapid response to emerging pathogens

The adaptability of Far-UVC light technology is a significant asset for pandemic preparedness. Unlike some traditional disinfection methods that require time-consuming setup or the procurement of specific chemicals, Far-UVC devices can be deployed relatively quickly. This capability enables a rapid response to emerging pathogens, helping to contain the spread of diseases in the early stages.

Safer travel and hospitality

Industries heavily impacted by pandemics, such as travel and hospitality, can benefit immensely from Far-UVC technology. It can be integrated into ventilation systems, providing continuous disinfection of air in airports, airplanes, hotels, and restaurants. This type of integration not only reassures travelers but also supports the recovery of these industries by creating safer environments for both customers and employees.

Minimizing super-spreader events

Super-spreader events have been a significant driver of pandemics and influenza viruses, where a single infected person can transmit the virus to a large number of people. Far-UVC light can help mitigate these events by disinfecting the air and surfaces in crowded spaces, reducing the likelihood of mass transmission.

Applications of Far-UVC light

Far-UVC light has a high level of potential applications in pandemic preparedness and beyond. Even outside of medical care settings such as hospitals, clinics, and nursing homes, Far-UVC can effectively combat the spread of germs and pathogens in essentially any indoor setting. Here are just a few examples:

Schools and universities

Educational institutions can create safer environments for students and staff by installing Far-UVC systems in classrooms, libraries, and common areas.

Public transportation

Buses, trains, and subway systems can integrate Far-UVC technology to reduce the risk of virus transmission among commuters.


Businesses can maintain safer workplaces by incorporating Far-UVC light in their common areas.

Retail stores

Stores can reassure customers by utilizing Far-UVC technology to disinfect shopping areas and prevent the spread of viruses.

Residential spaces

Far-UVC devices can be used in homes to provide an added layer of protection for families, particularly during pandemics.

Summing it all up

While we cannot predict the future with certainty, it is essential to remain proactive in our efforts to prepare for potential pandemics. Innovative technologies like Far-UVC light offer promise in understanding how to better interact with and prepare for pandemics.

With its safety for humans, effectiveness at killing microorganisms, and diverse applications, Far-UVC light can be a valuable tool in safeguarding public health and reducing the risk of infectious disease transmission. As we continue to invest in research and development, Far-UVC technology could become an indispensable asset in our efforts to create safer environments and better protect our communities in the face of future health challenges.
