If an event has the Clean Air Club badge, it means that the space (including green rooms and backstage where possible) has at least one HEPA air purifier running to reduce the number of airborne pathogens in the room.
In practical terms, this means that a Clean Air Club event is less likely to be one in which Covid-19 and other respiratory diseases are spread, making it Covid-safer for everyone. While there is still a risk of catching Covid when we are in public, there are many ways to mitigate that risk (including masks, staying home when sick, etc.). Air filtration is an important and under-utilized element of this multifaceted risk-mitigation effort.
If a venue has the Clean Air Club badge, it means that the space far exceeds the minimum air changes per hour recommended by the CDC for safety from airborne pathogens (6ACH). A venue "stamp of approval" is much harder to get!
