The Centers for Disease Control and Prevention (CDC) recommends opening windows to reduce the spread of coronaviruses, and state health departments are encouraging the same measures to slow the transmission of Covid-19, specifically. “Changing the room air is a widely used measure for infection prevention and control,” says Stephen Morse ...

From the beginning of this pandemic, buildings managers, airport operators, restaurateurs, and the public have been being inundated with product promotions claiming to have the latest and greatest technology to protect workers, travelers, and customers from infection with SARS-CoV-2. Products are varied, including surface sanitizers, air filtration...
Ventilation, natural or mechanical, is the main way that the risk of airborne infection indoors is reduced. For hospital airborne infection isolation and procedure rooms, the U.S. Centers for Disease Control and Prevention (CDC) recommends 6 to 12 room air changes per hour (ACH) with infection-free outdoor air, or air that has been filtered or othe...
Presented with particulate air contamination, a standard engineering response is to filter the air. High-efficiency air filters can be used in building ventilation systems to assure that fewer than 99.9% of respirable-size particles are recirculated back into rooms, essentially converting recirculated air into the equivalent of infection-free outdo...
Natural ventilation is by far the most common form of room decontamination worldwide that can be highly effective with proper building design and favorable outdoor conditions. However, windows are often closed in inclement weather, and wind currents are not always conducive to good air exchange within buildings. With global warming, moreover, incre...
These comprise a wide range of devices in price and performance. They usually consist of a box with a fan or blower and air filters, with or without UV or more sophisticated technologies for trapping particles or inactivating pathogens. The major determinants of room-air cleaner efficacy are: 1) the flow rate of air processed (clean-air delivery ra...
Upper-room germicidal UV (GUV) fixtures are a more than 80-year-old technology, well-proven, safe, and underused technology for airborne infection control. Upper room GUV works by flooding the “upper room” (above the heads of occupants) with sufficient germ-killing ultraviolet light to rapidly inactivate airborne pathogens. All known pathogenic mic...
A variety of ionizers (bipolar, unipolar, and cold plasma) are marketed to generate positive and negative ions, deployed directly into occupied rooms or within filtration systems, to cause infectious particles to be attracted to filters or stick to each other and then settle out of the air and onto surfaces where they can no longer be inhaled. The ...
May 26, 2021 · "Now that we are able to meet indoors, opening windows and doors to improve ventilation and prevent the spread of COVID-19 becomes even more important." Study authors were supported by the National Institute for Health Research Health Protection Research Unit (NIHR HPRU) in Emergency Preparedness and Response, a partnership between Public Health England, King’s College London and the ...
Mar 19, 2020 · Handwashing. According to the World Health Organization, this is the best way to protect yourself against COVID-19. The virus causes infection when it enters your eyes, mouth or nose — usually ...
Jul 25, 2024 · Long before the COVID-19 pandemic, experts understood the role of airborne transmission of respiratory infections and that the most important control measure to reduce the risk of infection is to remove pathogens from the air through ventilation, filtration, or inactivation by ultraviolet (UV) C radiation.
keep vents and fans clear. change the filter as recommended by the manufacturer. If possible, run the HVAC system fan continuously. This will increase the delivery of clean air and reduce the number of infectious particles indoors. For more information, refer to: COVID-19: Guidance on indoor ventilation during the pandemic.
