Smoke from wildfires has affected much of the Midwest and Northeast, leading to poor air quality and hazy skies. Some areas currently have the worst air quality globally. Health experts advise staying indoors and using masks when outside. To prevent smoke from entering your space, keep windows and doors closed in both homes and vehicles.
Using air conditioning can help maintain cleaner air. In cars, activate the air recirculation button to prevent outside air from entering. This button helps reuse existing air inside the car, keeping it cool and improving gas mileage.
Check your home’s AC unit to ensure it recycles indoor air, as some have a fresh air function that could bring in smoky air. Dr. Brian Christman from Vanderbilt University advises against using the fresh air feature during smoke events. Instead, switch to recirculation and ensure the filter is in good condition, ideally rated MERV 13 or higher.
To further keep indoor air clean, cover door cracks with blankets or towels. If available, run an air purifier, particularly in the room where you spend the most time. Jennifer Stowell, a research scientist, emphasizes the importance of maintaining clean indoor environments during such times.
Conditions are predicted to improve by the weekend as rainstorms may occur. Nexstar meteorologist Darrius Stringer suggests that air quality could significantly improve by Sunday.
