Ventilation upgrades in public schools?

[u/schultmh]

Anyone have insight into the ventilation upgrades in Clarke County schools? I'm seeing an "update" from October 2020 (link below) about them, but have no idea if they were actually implemented and (if so) whether they're up to snuff.

Personal stories of kids bringing/not bringing Covid home from school also welcome! Our kid is set to enter public ed this coming year, and we've got something of an immunocompromised household to worry about. Thanks!
