Fans and Air Flow
I've seen a lot of nonsense on here about fan and circulation. (Looking at you John F)
So, lets put some real math to the problem.
Paul has repeatedly mention a 1000 sqft room, assume a standard 8ft ceiling - 8000 cubic feet
Fans are rated in CFM (Cubic Feet Per Minute) - 8000/60 = 133 CFM to do a standard complete air change over in 60 minutes. 533 CFM for every 15 minutes
Below is a link for over 80 fans that could work in this application, and this is just stock on Digikey. All of these fans are between 80-150mm.
Another aspect to consider is standard air changeover in a room. This article talks abou viral transmission and references a 3x air turnover per hour in a standard office place.
