Here was my HN comment in July of 2020 with a few months of hindsight referencing research from March 2020: “I am still shocked: months after research has shown that SARS-CoV-2 is airborne stable in aerosol form for over 3 hours, we still aren’t telling the public that room air purifiers are a ‘good thing’ (for making indoor air like outdoor air - in regards to virion density per cubic air volume) The filter technology is essentially the same as in the N95, orders of magnitude more effective than cloth masks. Put these indoors, multiple per classroom/working space to help the air refresh in sub 5 minute intervals. … Aerosol transmission is leading cause for indoor superspreader event, ergo N95 masks are required when someone is indoors for an extended period of time. The govt. response failure is from the fact we weren’t making N95s at full production for the past decade plus to prepare for this.” My expertise is adjacent to this area, so it was easy to see through the incompetence. It might just be the government doesn’t pay enough to hire competent scientists who typically go straight to industry.
