The air quality in Los Angeles has significantly worsened due to an unprecedented string of wildfires. High winds have caused the heavily polluted smoke to spread far beyond the immediate fire zones.
How Worried Should You Be?
Research from the University of California has found that the air is now 10 times more toxic than regular air pollution. The Department of Public Health has declared the air quality in Los Angeles County as unhealthy, warning that smoke from these wildfires contains unusually high levels of pollution that can severely impact health. Given the persistent poor conditions throughout Los Angeles County, everyone—even those far from the flames—should take steps to avoid smoke inhalation, both outdoors and at home.
Air Quality Index (AQI)
The U.S. Environmental Protection Agency categorizes air quality by the Air Quality Index (AQI) using colors and numbers:
Below 100: Generally safe (yellow is acceptable; green is ideal).
101–150 (Orange): Unhealthy for sensitive groups.
151–200 (Red): Unhealthy for everyone.
201–300 (Purple): Very unhealthy.
301 and higher (Maroon): Hazardous.

General Tips
Monitor air quality: Check updates for your area regularly. airnow.gov (they also have an app, or check via the Weather app on your phone). Enter your address or ZIP code, and get current air quality reading and breakdown of the pollutants in your area.
Stay indoors: If you're in a danger zone, limit outdoor exposure. Children, in particular, should remain inside as their lungs are still developing.
Seal your home: Keep doors and windows closed to prevent indoor pollution. Open them only when air quality improves to allow fresh air in.
Maintain air filters: Ensure your air conditioner’s filter is clean and use the recirculate setting to avoid pulling in outdoor smoke.
Avoid Activities That Worsen Indoor Air
Do not:
Smoke.
Burn candles or incense.
