AIRBORNE INFECTION RISK PLUMMETS IN FACE OF METAL NANOPARTICLE SPRAY

Summary from the TLDR newsletter

A new sprayable coating applied to standard air filters may help protect against airborne respiratory infections like measles, influenza, SARS, pneumonia, tuberculosis, and COVID-19. It provides a greater than 99% antiviral activity while also completely stopping bacterial growth. The spray doesn't interfere with the effectiveness of filters doing their normal job of removing other particles from the air. There are many other similar technologies in the works, but they will all need more development before they become commercially available.
