I help organize a contra dance that requires N95s at half of our dances. Are there ways we could have a hall as safe as this but without the ways N95s make it harder to dance? I'm excited about supplementing ventilation and surgical masks with glycol vapor and 222-nm UVC: https://www.jefftk.com/p/alternatives-to-masks-for-infectious-aerosols

@jefftk Do you think it would be a good option to have some kind of system where fans blow air through a container where UV light is produced/contained? In principle seems like this could be much higher volume than pushing through filters?

@dynomight It's possible to use UV in a definitely-no-humans space, and the thing to look for here is "in-duct uv".

But unless the inside of your space is super UV-reflective you lose a lot of the benefit of UV being light: instead of rays covering a big room they are stuck inside your box.
