Wildfires in Southern California are tragically common during the fall. Even when your home isn’t in the path of a raging fire moving through dry brush, the smoke, soot, and other contaminants these fires bellow into the sky have a massive negative affect on air quality for many miles around. For areas downwind of the fires, air quality can be affected by up to a hundred miles.
How bad can the air quality get due to wildfires? Around 60 times worse than health standards, with particulates as high as 1,500 micrograms per cubic meter. To give you perspective on this, the threshold for healthy conditions according to the World Health Organization is 25 micrograms per cubic meter.
