Far-UVC Light Safely Kills Airborne Coronaviruses

More than 99.9% of seasonal coronaviruses present in airborne droplets were killed when exposed to a particular wavelength of ultraviolet light that is safe to use around humans, a new study(link is external and opens in a new window) at the Vagelos College of Physicians and Surgeons at Columbia University Irving Medical Center has found.

Can UVC be used to fight COVID Omicron, Delta and other Variants?

Yes, UVC can be used to fight Delta and all the new COVID variants including Omicron, Delta Plus and Lambda.
It's becoming increasingly clear that our societies are going to be dealing with COVID Omicron, Delta, Lambda, and other variants of the SARS-CoV-2 virus.

UV Lights and Lamps: Ultraviolet-C Radiation, Disinfection, and CoronavirusFar-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses

Given the current outbreak of Coronavirus Disease 2019 (COVID-19) disease caused by the novel coronavirus SARS-CoV-2, consumers may be interested in purchasing ultraviolet-C (UVC) lamps to disinfect surfaces in the home or similar spaces.

Repetitive irradiation with 222nm UVC shown to be non-carcinogenic & safe for sterilizing human skin

Joint research between Kobe University and Ushio Inc. has provided proof for the first time in the world that direct and repetitive illumination from 222nm ultraviolet radiation C (UVC), which is a powerful sterilizer, does not cause skin cancer.

Predicting airborne coronavirus inactivation by far‑UVC in populated rooms using a high‑fidelity coupled radiation‑CFD model

There are increased risks of contracting COVID‑19 in hospitals and long‑term care facilities, particularly for vulnerable groups. In these environments aerosolised coronavirus released through breathing increases the chance of spreading the disease

Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses

A direct approach to limit airborne viral transmissions is to inactivate them within a short time of their production. Germicidal ultraviolet light, typically at 254 nm, is effective in this context but, used directly, can be a health hazard to skin and eyes.

How to Tell the Difference Between COVID-19 vs. Flu

Flu season is here. Paired with the ongoing battle with COVID-19, experts have been warning that we could have a “twindemic” on our hands this year — an influenza epidemic unfolding in the middle of a relentless COVID-19 pandemic.

Far UV-C Radiation: Current State-of Knowledge

The COVID-19 pandemic has heightened awareness of the risks associated with disease transmission bysurface- and, particularly, airborne-associated pathogens; this risk awareness brings a desire for solutions.UV-C radiation (at shorter wavelengths outside the visible spectrum) has been employed for air and surfacedisinfection since the 1940's.
