The Chicago area has been under air quality alerts for most of last week, due to smoke from Canadian wildfires.

At one point last week, Chicago had the worst air quality in the world.

Health professionals point out that the poor air quality is particularly concerning for active kids and adults who have respiratory issues. It is advised that those affected should move indoors and seek medical help if needed.

Experts recommend using an N95 mask when outdoors, and ensuring that home air filters are updated to maximize the effectiveness of air conditioning systems.
