Using valved respirators to prevent the spread of COVID-19 has been discouraged due to concerns that valves do not effectively filter particles from exhaled air, but few studies actually have looked at this. Now, researchers report in Environmental Science & Technology Letters on their performance.
A media comprised of a sandwich of materials, tested by Sandia National Laboratories, is being manufactured into N95-like respirators that could be used in local medical facilities. The project originated from the urgent need for personal protective equipment when the COVID-19 outbreak began.
Researchers with the DHS S&T developed a do-it-yourself solution to decontaminate personal protective equipment (PPE) using a programmable multicooker.
