Vaccinated or booster?
Fairly low, what is specific concern. Most respirators leak more than 5%, so the risk really is airborne virus built up in room and eye exposure risk.
Ventilation, volume all are high factors
Everyone vaccinated and boosted. The building supposedly runs on MERV-13 but the room felt stuffy.
The type of filter in the building doesn't matter if the air isn't pushed through that filter. That's why the Air Changes per Hour (ACH), that tells you how often the air in a space is completely replaced, is a more important measure.
