THE SHORT ANSWER

Bring in cleaner outdoor air when appropriate, improve ventilation and consider suitable air filtration. Cleaner air is one part of reducing respiratory exposure indoors.

What is useful to understand?

The right plan depends on the room, building system and outdoor conditions. If outdoor smoke or poor air quality is present, simply opening windows may not be the best option. Ask venue hosts about airflow before an event rather than assuming a spacious-looking room is well ventilated.

What can you ask or do next?

  1. Check outdoor air conditions.
  2. Use ventilation and filtration suited to the space.
  3. Consider outdoor or less crowded alternatives.

One more question

Does an air purifier make a gathering risk free?

No. Filtration does not replace other precautions or staying home when sick.
