Wildfire Smoke and Indoor Air in the Bay Area
How wildfire smoke affects indoor air, steps agencies recommend during smoke events, and how to check particulate levels at home.
This guide is general information, not medical advice. If you have health concerns, please consult a medical professional.
Smoke gets inside
During smoke events, fine particles (PM2.5) can enter homes through windows, doors, gaps and ventilation systems.
Steps agencies recommend
Check AirNow for local air quality, keep windows and doors closed during heavy smoke, use high-efficiency HVAC filters where your system allows, and consider a portable HEPA air cleaner sized for the room.
Follow guidance from public health officials and your medical provider, especially for sensitive groups.
Checking your home
Particulate readings taken during and after smoke season show how well your home keeps smoke out and how quickly it recovers.
