Global Lighting Association- Position Statement on Airborne Pathogen Inactivation

GUIDELINES FOR QUANTIFICATION OF AIRBORNE PATHOGEN INACTIVATION BY UVGI TECHNOLOGIES   UV-C and urgent need for quantification guidelines Ultraviolet germicidal irradiation (UVGI) air disinfection technology is an established method to reduce infection risks caused by a wide range of contagious airborne diseases. However, it does raise the following questions: 1. Does it work? and … Read more

Calls for post-Covid ‘revolution’ in building air quality

Prof Noakes said that a “revolution” is needed in how governments regulate indoor air quality and in how the issue is handled in degree and apprentice courses. Another scientist involved is Dr Julian Tang, honorary associate professor and clinical respiratory virologist at the University of Leicester. He says indoor spaces with poor ventilation are a … Read more

Covid Is Airborne, Scientists Say. Now Authorities Think So, Too

“Cleaner indoor air won’t just fight the pandemic, it will minimize the risk of catching flu and other respiratory infections that cost the U.S. more than $50 billion a year, researchers said in a study in the journal Science on Friday. Avoiding these germs and their associated sickness and productivity losses would, therefore, offset the cost of … Read more

Ten scientific reasons in support of airborne transmission of SARS-CoV-2

the lancet - UVC for killing COVID

“If an infectious virus spreads predominantly through large respiratory droplets that fall quickly, the key control measures are reducing direct contact, cleaning surfaces, physical barriers, physical distancing, use of masks within droplet distance, respiratory hygiene, and wearing high-grade protection only for so-called aerosol-generating health-care procedures. Such policies need not distinguish between indoors and outdoors, since … Read more

The Best Way to Improve Indoor Air Quality

foto stick UVC disinfection

Heating, ventilation and air conditioning (HVAC) systems are the perfect breeding ground for bacteria, viruses, pathogens, spores, molds, and more. Air recirculation, temperature fluctuations, and humidity within these systems promote the growth and distribution of microorganisms. This environment allows them to combine with each other in complex ways, and settle all over surfaces inside an HVAC … Read more

CDC Updated Guidance

Consider using ultraviolet germicidal irradiation (UVGI) as a supplemental technique to inactivate potential airborne virus in the upper-room air of common occupied spaces, in accordance with industry guidelines.  

How air pollution is causing a rise in coronavirus deaths

how smog is increasing covid deaths

It is a well-known fact that air pollution can cause problems with your breathing and respiratory system, and recent research has shown that it is also impacting the severity of COVID-19 symptoms. The study by the IZA Institute of Labor Economics in the Netherlands revealed that those regions in the country with high pollution rates … Read more
