How to Protect Respiratory Health During Poor Air Quality Conditions
This guide outlines practical steps to minimize exposure and protect lungs when air quality declines due to pollution, wildfires, or other factors. Monitor official alerts and consult healthcare providers for personalized advice.
Tools and materials
- Air quality monitoring app or website
- N95 or equivalent respirator masks
- Portable air purifier with HEPA filter
- Extra mask filters
- Window sealing tape
- Humidifier
Steps
1. Monitor air quality
Check real-time AQI readings from trusted local sources before any outdoor activity and plan accordingly.
2. Limit outdoor exposure
Stay indoors during peak pollution hours, especially if AQI exceeds 100, and reschedule exercise or errands.
3. Seal indoor spaces
Close windows and doors, use weather stripping or tape to block drafts, and run HVAC systems with clean filters.
4. Use respiratory protection
Wear a properly fitted N95 mask outdoors and ensure it seals well around the nose and mouth.
5. Improve indoor air
Operate HEPA air purifiers in main living areas and maintain moderate humidity with a clean humidifier.

FAQ
When should I wear a mask during poor air quality?
Wear an N95 or equivalent whenever AQI is unhealthy and you must go outside, replacing it when soiled or breathing becomes difficult.
Are air purifiers effective against smoke and pollutants?
HEPA-filter purifiers can reduce indoor particulate levels when used in sealed rooms; follow manufacturer guidelines for filter changes.
How long can poor air quality last after a wildfire?
Conditions may persist for days or weeks depending on wind and fire activity; continue monitoring until official advisories end.
