While you cannot control outdoor air quality, you can take steps to reduce your exposure and improve the air you breathe at home.
Monitor Air Quality
Check local AQI readings before outdoor activities. High-risk times include rush hour traffic peaks, hot summer afternoons (ozone), temperature inversions, wildfire season, and industrial incidents. Plan strenuous activities for times when air quality is better.
Protect Sensitive Groups
Children (developing lungs), elderly, those with asthma or respiratory conditions, people with heart disease, pregnant women, and outdoor workers need extra precautions. They should limit outdoor activity at lower AQI thresholds than the general population.
Improve Indoor Air
Use HEPA air purifiers sized for your room. Ventilate when outdoor air is clean. Avoid burning candles or incense. Use exhaust fans when cooking. Keep windows closed during high pollution. Remove shoes at the door to avoid tracking in pollutants.
During High AQI
Limit outdoor exercise and stay indoors when possible. Close windows and doors. Run air purifiers on high. Wear N95 masks if you must go outside. Avoid driving, which contributes to pollution and exposes you to higher concentrations.
