If you live in Detroit, it is strongly recommended that you don't breathe.
As someone in WI, this whole region is awful so please be careful friends! (7/16/2026)
Please put on your N95s. The same ones used for covid will filter particulate pollution. I lived in a city with yearly winter pollution levels like this. If you can pay for it, you might as well get an indoor air filter to sleep in.
If you can't afford a proper air purifier or can't find one in stock, these are sometimes cheaper to build:
Make sure you get the best rated furnace filters you can (usually the one with the highest numbers on the package in the store). If getting all those is too expensive, even one of those furnace filters taped tightly to a box fan (to force the air through the filters so it doesn't come in through the cracks) can help pretty substantially in a small room.
