In an emergency an air cleaner made out of a fan and bedsheet sized "sock" will reduce your exposure to particles from wildfire smoke. doi.org/10.1080/2374...
If you are impacted by wildfires and want to use a air cleaner to lower your indoor exposure to smoke: - The air cleaner should have a CADR (in cfm) that is 2/3 the square feet of the space you place it in. - The volume of space you put it in should be determined as that between closed doors.
