Frequently Asked Questions
How is wildfire smoke risk calculated?
Smoke risk scores (0-100) combine multiple factors: proximity to recent wildfires, county fire frequency over the past 5 years, historical smoke days, and geographic position relative to typical fire corridors. Higher scores indicate greater smoke exposure risk during fire season.
How can I protect myself from wildfire smoke?
Use a HEPA air purifier indoors, wear N95 or KN95 masks outdoors during smoke events, seal windows and doors, and monitor AirNow.gov for real-time air quality. Create a clean room in your home with the purifier running and windows sealed.
