Health Guidance
Protect Your Health
on High-AQI Days
Air pollution affects everyone differently. Follow these evidence-based tips to reduce your exposure and protect your respiratory health.

Outdoor Exercise
Check AQI before outdoor workouts. Above 100, consider moving exercise indoors.
😷
Wear a Mask
N95 or KN95 masks filter fine particles effectively when AQI exceeds 150.
🏠
Stay Indoors
Keep windows closed and use air purifiers with HEPA filters on unhealthy days.
👶
Protect Children
Kids are more vulnerable. Limit outdoor play when AQI is above 100.
