- What's the science behind how face masks and respirators work, and how do they prevent you from inhaling potentially harmful airborne particles or viruses like covid-19?
As respiratory protection against airborne coronavirus becomes increasingly important, Risk Bites dives into the aerosol science behind how face masks and respirators work, and explores what makes for good protection against exposure to airborne particles and droplets, whether it’s a professional product, or a DIY face mask.
UPDATED to include electrostatic collection. Original video: • How do face masks and ...
