Some years back I had a professor who was doing research on the lack of air circulation leading to CO2 buildup in classrooms. CO2 has pretty deleterious effects of student achievement. Turns out oxygen is important for cognition, who knew? I can only assume it's worse with face masks.

- shadilay 5y agoSurgical masks are designed to stop droplets, not aerosols so they're pretty loose. The mask is not form fitting around the nose. OR's also have dedicated filtration/HVAC systems with HEPA filters. I researched this when I was looking for a filter system for wildfire smoke.
