First, I’m not questioning the recommendation to stay indoors, or that poor air quality is bad for your health.
I don’t understand how staying inside is better, especially in homes (like mine) that don’t have central ventilation or air filters. My home isn’t air-tight, and I can’t recycle the air I’m breathing out – so there must be new air coming in from outside.
Can anyone explain *why* it’s safer to stay indoors? How is the air inside safer to breathe?

Even without specific air filters there is some level of filtration. The air in your house will have to pass through narrow vents and slow down. And this cause the particles in the air to settle out and fall down as dust. It is at least better then nothing.
