What To Do......What To Do?
Interesting reading if you are so inclined:
https://www.nytimes.com/interactive/2021/02/26/science/reopen-schools-safety-ventilation.html
The NYT article shows air ventilation issues as well as I have ever seen it, and I have been ventilating a long time.
That was for the classroom, this is for the house:

Stick around or check back later, I'll show you some ideas on what to do to help.
Thanks
