🙌 Great news in New Scientist. An experimental study shows that air filters in classrooms:
Reduced absence by:
👩🏫 12.5% or 1.3 days per pupil
Reduced PM2.5 by:
🚸 32%
Air filtration is a simple way to improve life for everyone. So what's stopping the government?!

Firefighters, first responders, nurses, and doctors rely on *NIOSH-approved* respirators. (During the pandemic we saw *many* counterfeit respirators going to hospitals.) The program that certifies respirators was eliminated.
