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 ...

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 ...

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 ...

The Illuminating Engineering Society (IES) recently released a report to combat the seemingly conflicting statements and opinions about the disinfection capabilities and safety of germicidal ...

LEDs emitting light in the range of 200 nm to 400 nm are classified as UV LEDs. Within this range, there are three bands, UV-A with wavelengths from 300 nm to 400 nm, UV-B with wavelengths between 280 ...

Marktech Optoelectronics a Leading Manufacturer of Photodiode Photodetectors and LED Emitters in UV, Visible, NIR, SWIR Wavelengths Silanna Group is a privately funded Australian semiconductor ...

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, ...

Airborne transmission of infectious agents resulting in disease has been well-documented. There has been renewed interest in applying engineering controls to remove or inactivate causative agents.

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 ...

The Illuminating Engineering Society (IES) recently introduced the standard, ANSI/IES RP-44-21 Recommended Practice: Ultraviolet Germicidal Irradiation. This new standard focuses on the use of UVGI ...

Germicidal UV-C lighting (Steril-Aire). Germicidal UV-C lighting is installed in the air handling units of HVAC systems and kills 99.9 percent of biofilm on the coil lighting. As a result, the air ...

While useful for killing pathogens including SARS-CoV-2, 222-nanometer UV lights may produce harmful compounds in indoor spaces, and should be used with ventilation, researchers have found. Many ...
