Airborne viral transmission risk is easily monitored with cheap handheld CO2 sensors.
Mirv 13 filters and a box fan from Costco is a cheap way of trapping large floating blobs of moisture recently expelled from people's lungs.
Get yourself a handheld co2 monitor and a decent fitting mask.
Make a #CorsiRosethanthal filter box. It's so effing easy.
Share ppm readings at McDs, Starbucks, waiting rooms.
Just had a friend laughed at and labeled a sham science promoter for telling their doctor that his air-tight waiting room with coughing patients was stuck at nearly 3000ppm CO2, whereas 1k ppm is the limit for noninfectious viral safety in the US, and the saner 800ppm in Germany.
Time to kit up, defend yourself if you're going to participate in society, and that means sensor and mask and a box at home.
Kit up and share. You can do it, because it's easy, cheap, and it works.
