Officials suggest staying inside, avoiding physical activity and running the AC or air purifier in your home.

“Staying inside with your windows and doors closed, minimizing heavy outdoor exertion, potentially wearing an N-95 mask if you have to be outside, running an air purifier or an air conditioner can all help reduce exposure,” Epstein said.

Don’t use an ionizer air purifier in your clean air space because it can create ozone.

Don’t: If you made a DIY air purifier, do not leave it unattended.

These purifiers clean a certain amount of square footage, though, so when buying a purifier, make sure it can clean the air in the room you’ve chosen.
