Wildfire Smoke Chokes Chicago: Health Alert Issued

Chicago is bracing for another wave of wildfire smoke from Canada, with health officials warning of unhealthy air quality on Thursday. Rush Medical Center experts predict high and dense particle levels, adding to existing concerns from a heat wave and an extended Air Quality Alert. The smoke, originating from fires across Canada and neighboring regions, is expected to infiltrate homes through various openings and air duct systems. HVAC professionals are seeing an increase in calls related to heat and soot buildup on filters, advising residents to change them proactively to prevent potential damage to home systems.

Respiratory therapists emphasize that everyone may experience irritation to the eyes and nose due to the smoke. They strongly advise checking air quality reports before engaging in outdoor activities like running and to shorten exercise duration if necessary. During driving, keeping windows closed and using the recirculation setting on car air conditioners is recommended. Homeowners with window units should also use their recycle feature. Pet owners are cautioned to limit outdoor time for their animals and to ensure clean air environments indoors with purifiers. Wearing masks is advised if going outside is unavoidable, though standard surgical masks are not effective against these particles.
