16. filtering the air may be good (to some extent, anyway) but circulating air might actually be bad

depending on the actual flow of air within the restaurant.

there was a study someone posted here a while ago that showed someone got infected from someone else in a restaurant 20+ feet away after only 5 minutes because the airflow carried the virus from an infected person to the person who caught it. i think that was just from ceiling fans, but any way a breeze is generated can be problematic or helpful.

ideally, i guess you would want airflow one way only (fresh air comes in one side of the building and out the other) and to position people so no one is downstream from anyone else. otherwise, still air might be better as the virus would tend to stay closer to the people already infected.

actually, if airflow could somehow be designed to go down -- fresh air from the ceiling and out through holes in the floor -- that would probably be best. haha, maybe that will catch on...

No. They are sealed off, outside. No ventilation. we can do it Jan 2021 #18

In my state, the tents have to be open on two sides RainCaster Jan 2021 #9

I see some like that, many completely closed --south sound. Pobeka Jan 2021 #13
