Circumventing Covid-19 with better ventilation and air quality

Gathering outdoors has provided people a safer alternative to meeting inside during the Covid-19 pandemic. But for those who spend their days in crowded indoor spaces — workers in office buildings and industrial facilities, students in schools, and the like — how can their indoor environments be made more similar to the outdoors? With better air quality and ventilation. Yet federal regulations are insufficient for improving indoor ventilation and few states are moving to improve it. We examined the Covid-19 US State Policy database and found that only Michigan, Minnesota, New Jersey, Oregon, and Washington have explicit occupational safety and health standards to promote better air and/or ventilation quality.
