Far-UVC Against Influenza
Journal of Hospital Infections / February, 2021 “The 222-nm UVC is able to inactivate a wide spectrum of microbial pathogens. In comparison with the conventional 254-nm UVC, the germicidal effect of 222-nm UVC to the fungal hyphae and spores is low, but the 222-nm UVC exhibits strong germicidal effect to the bacterial endospores.” Link to […]
UVC for NASA: Reducing Bioburden in Spacecrafts with Far-UVC Light
Advances in Space Research / January, 2021 “The major advantage of far-UVC (222 nm) compared to traditional germicidal UVC (254 nm) is the potential for application throughout the spacecraft assembly process in the presence of humans without adverse health effects due to the limited penetration of far-UVC light into biological materials.” Link to article.
Far-UVC Efficiently and Safely Inactivates Airborne Human Coronaviruses
Nature Scientific Reports / June, 2020 “We previously demonstrated that 222-nm far-UVC light efficiently kills airborne influenza virus and we extend those studies to explore far-UVC efficacy against airborne human coronaviruses alpha HCoV-229E and beta HCoV-OC43.” Link to article.
Far-UVC Current Knowledge Summary From the Leading, Independent Experts
International Ultraviolet / May, 2020 “The significance of Far UVC is that, whereas exposure to conventional germicidal UV (250-280 nm) at germicidal doses is potentially hazardous, biophysical and experimental evidence suggest this is not the case for Far UV-C…” https://iuva.org/resources/covid-19/Far%20UV-C%20Radiation-%20Current%20State-of%20Knowledge.pdf
Number of Mechanical Air Changes per Hour to Reduce Airborne Pathogens (CDC)
US CDC / July, 2019 “Lack of adherence to established standards and guidance (e.g., water quality in dialysis, proper ventilation for specialized care areas such as operating rooms, and proper use of disinfectants) can result in adverse patient outcomes in health-care facilities.” Link to article
Far-UVC Against MRSA
Public Library of Science One / February, 2018 “Being safe for patient and hospital staff, our results suggested that far-UVC light (222 nm) might be a convenient approach to prevent transmission of drug-resistant infectious agents in the clinical setting.”
Public Health Reports / January, 2010 The History of Ultraviolet Germicidal Irradiation for Air Disinfection
Public Health Reports / January, 2010 The History of Ultraviolet Germicidal Irradiation for Air Disinfection “There is a long history of investigations concluding that, if used properly, UVGI can be safe and highly effective in disinfecting the air, thereby preventing transmission of a variety of airborne infections. … This article reviews that history of UVGI […]
