Many efforts to reduce transmission of diseases like COVID-19 and the flu have focused on measures such as masking and isolation, but another useful approach is reducing the load of airborne pathogens ...

As COVID-19 sidelines many businesses, the demand for building lighting has dimmed. After all, there’s no need for lights in padlocked stores, restaurants, entertainment venues, and the like. That ...

How ultraviolet light (UV) works as a disinfection technology depends upon the wavelength(s) being employed. The UVC band with a wavelength of 200-280nm has emerged as a viable solution for interior ...

Perhaps the first randomized trial of an air cleaning device for nursing homes showed no significant impact on the primary endpoint for acute respiratory infection incidence. A secondary analysis did, ...

For nearly a century, scientists have known ultraviolet germicidal irradiation (UVGI or UV-C) energy deactivates airborne and surface-bound viruses, mycoplasma, bacteria, and fungi. Light in the 253.7 ...

A new research paper titled "Germicidal lamps using UV-C radiation may pose health safety issues: a biomolecular analysis of their effects on apoptosis and senescence" has been published in Aging. The ...

As the threat of measles and other infectious diseases continue to make headlines, more and more building and facility managers are searching for ways to reduce the threat from contagious airborne ...

When winter chill strikes, people stay indoors more often, giving airborne pathogens -- such as SARS-CoV-2 and influenza -- prime opportunities to spread. Germicidal ultraviolet (GUV) lamps can help ...

Germicidal electrical equipment typically incorporates light to inactivate germs and viruses. It’s accomplished by producing light output in a range that may render microbes non-infectious at a ...

Ultraviolet light systems have started to gain popularity as a way to clean large swathes of schools quickly and frequently. For example, according to a February EdWeek Reseach Center survey, 13 ...
