Why Far-UVC?

We use the term “Far-UVC” to refer to a specific range within the ultraviolet (UV) spectrum. “Far” in this context is used to distinguish this range from other parts of the UV spectrum. This range has recently attracted attention because studies suggest that Far-UVC light can inactivate viruses and bacteria without harm to human skin and eyes, […]
Making Indoor Air Safe with Far-UVC

During the COVID-19 Pandemic, building owners were forced to focus on Indoor Air Quality (IAQ). Many owners found that their Heating Ventilation and Air Conditioning (HVAC) systems were outdated or poorly designed. Many buildings had structural issues that prevented good ventilation, and even more had HVAC systems with clogged or missing air filters, or some other challenge like […]
Mould study highlights safer far-UVC light cleaning alternative

Research suggests that to prevent common mould growth, low-dose far-UVC light could be applied as a chemical-free addition to manual cleaning of indoor surfaces.
Interview with Dr. David Brenner of Columbia University on far-UVC 222-nm and the COVID pandemic

The recognition that respiratory pathogens which cause COVID-19 were transmitted through airborne mechanisms was a critical insight into the nature of the disease and the need to decontaminate airborne spaces to eliminate these pathogens.
Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?

At least as long as human beings have lived in large, close groups, respiratory viruses have been present — sometimes an annoyance, sometimes a catastrophe.
Far-UVC’s Role in the Path to Clean Air

Americans spend “an average of 87% of their time in enclosed buildings,” and air conditioning has been the transformative force in shaping the indoor environments we inhabit today.
IUVA 2024 Americas Conference

As new challenges continue to arise in public health, drinking water, reuse water and wastewater treatment, air pollution, hospital infections, ballast water treatment and industrial effluents, new applications emerge for UV technologies.
Indoor air systems crucial to curbing spread of viruses, aerosol researchers say

With a new strain of COVID on the rise, and flu season just getting started, we thought now would be a good time to consider what the pandemic has taught us about preventing the spread of potentially deadly respiratory infections.
UV and blue light take down drug-resistant bacteria

Bacterial resistance to antibiotics is a serious threat to public health. It contributed to an estimated 4.95 million deaths in 2019, and a recent review commissioned by the government of the United Kingdom warns that antimicrobial resistance could result in the deaths of 10 million people annually by 2050.
Columbia University to host first International Congress on Far-UVC Science and Technology (ICFUST)

Researchers from around the world are coming to Columbia University Irving Medical Center participate in the first scientific conference highlighting research on far-UVC light as a safe and effective technology for disinfecting indoor air.
