Daly City sits along major commute corridors and is home to thousands of residents who rely on daily travel to work, school, and appointments. During wildfire season, smoke can worsen quickly along routes and in transit settings where people are exposed for longer periods—especially when air quality drops while you’re already dealing with traffic, stress, and exertion.
Many Daly City households also spend time indoors with HVAC systems, open windows, and building ventilation that may not be optimized for prolonged wildfire smoke. When filtration isn’t adequate for foreseeable smoke conditions, residents can experience symptoms even if they never “went outside.”
