CNN: This invisible Covid-19 mitigation measure is finally getting the attention it deserves

CNN: This invisible Covid-19 mitigation measure is finally getting the attention it deserves. “Two-plus years into the Covid-19 pandemic, you probably know the basics of protection: vaccines, boosters, proper handwashing and masks. But one of the most powerful tools against the coronavirus is one that experts believe is just starting to get the attention it deserves: ventilation.”

CBC: 60 schools lacking ventilation systems now have HEPA filters to help combat COVID

CBC: 60 schools lacking ventilation systems now have HEPA filters to help combat COVID. “The 60 New Brunswick schools without integrated mechanical ventilation systems have a new tool to combat COVID-19 — HEPA, or high-efficiency particulate, filters. Forty-seven of the schools tested high for carbon dioxide, “but within the safe range,” CBC News has learned — almost double the number the Department of Education initially reported last fall. CO2 levels are considered a good indicator of ventilation efficiency.”

The Register: Will I inhale coronavirus at this restaurant? There’s an app for that

The Register: Will I inhale coronavirus at this restaurant? There’s an app for that. “The Ventilation View app relies on the presence of a CO2 sensor that Chiyoda Ward is giving away to businesses. Once that sensor is installed, and transmitting data, the venue – be it a restaurant and or some other place – will appear on a map, complete with an air quality rating. A rating of 1,000 parts per million or lower of carbon dioxide indicates there’s adequate ventilation to avoid coming down with coronavirus.”

NIST: Streamlined NIST Tool Could Help Homeowners, Renters Reduce Airborne Exposure to COVID

NIST: Streamlined NIST Tool Could Help Homeowners, Renters Reduce Airborne Exposure to COVID. “Leveraging ventilation and filtration has been an underutilized strategy for many residents throughout the pandemic because of the technical know-how required to implement these strategies. To help more people use this approach effectively, researchers at the National Institute of Standards and Technology (NIST) have developed a simple interactive webpage featuring the new Virus Particle Exposure in Residences (ViPER) tool. With ViPER — and some basic knowledge about their homes — homeowners and renters can learn how much certain actions, such as upgrading air filters or opening a window, may lower their risk of exposure to particles in the air that could potentially transmit COVID-19.”

Back to school: University of Cambridge online tool shows how ventilation reduces risk of Covid-19 transmission in classroom (Cambridge Independent)

Cambridge Independent: Back to school: University of Cambridge online tool shows how ventilation reduces risk of Covid-19 transmission in classrooms. “With pupils heading back in classrooms from March 8, a new tool created by Cambridge University researchers could help show schools how to reduce the risk of infections in classrooms. The scientists have built the tool Airborne.cam to show the impact of wearing masks, opening windows and taking more break times on reducing the amount of Covid-19 virus in the air.”
