Air Quality Index

Check real-time air quality levels including PM2.5, ozone, and pollutants with health recommendations.

Usage

Specify a location to get current air quality readings and health advisories.

Examples

• "What's the air quality in Los Angeles right now?"
• "Is it safe to exercise outdoors in Beijing today?"
• "Check PM2.5 levels in my area"

Guidelines

• AQI 0-50 is good; 51-100 is moderate; above 100 is unhealthy
• Sensitive groups should reduce outdoor activity above AQI 100
• Air quality varies throughout the day; check before outdoor plans
• Wildfire smoke can dramatically worsen air quality remotely
• Indoor air purifiers help during poor outdoor air quality periods
