Minnesota Faces Extended Air Quality Alerts Amid Wildfire Smoke

An air quality alert has been issued for Minnesota due to smoke from Canadian wildfires, with unhealthy levels expected to persist through Saturday. Vulnerable groups such as those with respiratory or heart conditions, children, and the elderly are advised to stay indoors, limit outdoor activities, and wear protective masks like N95 or KN95. To reduce indoor pollution, keep windows closed, use high-efficiency filters, and avoid activities that worsen air quality. People should also take precautions while driving and consider making DIY air purifiers to protect their health from wildfire smoke.
