"In the 316 classrooms that had mechanical ventilation with rates of 1.4–14 litres per second per person, the students’ risk of infection was reduced by at least 74% over a 4-month period at the end of 2021, compared with that for students in classrooms that relied on windows for ventilation. ... When ventilation rates were at least 10 l/s per student, the infection risk was 80% lower."

Indoor air is full of flu and COVID viruses. Will countries clean it up?

The current pandemic has focused attention to the importance of healthy indoor air and could spur lasting improvements to the air we breathe.

I'm sending this article to a public facing business I know.

This does two things.

1. It informs them of what they can do to keep their premises, customers and workers healthier and better protected.

2. If anyone gets seriously COVID sick from working or attending there it makes it clear that the employer knew of but did not take reasonable steps to ptotect the health of their wirkers and clients.

You might want to send it to businesses you know too.
