Tips to Protect Yourself from Unhealthy Air Quality in Jacksonville, FL

Regularly check Jacksonville’s AQI and avoid outdoor activities when the AQI is categorized as "Unhealthy" or worse. Plan errands or exercises for times when air quality improves, such as early mornings or after rainfall.

Keep windows and doors closed to prevent outdoor pollutants from entering your home. Use an air purifier with a HEPA filter to reduce indoor air contaminants. Additionally, ensure your HVAC system has clean filters and consider adding plants like peace lilies or snake plants, which can help filter indoor air naturally.

If you must be outside during high pollution days, wear a well-fitted mask, such as an N95, to minimize inhaling fine particles. Reduce outdoor exercise to avoid overexerting your lungs, and stay hydrated to help your body flush out toxins.

What are common pollutants that impact AQI in Jacksonville?
The main pollutants in Jacksonville’s air are ground-level ozone, particulate matter, and pollen. Ozone forms on hot, sunny days from car and factory emissions. Particulate matter comes from vehicle exhaust, construction, and occasional wildfires. Pollen levels, especially in spring and fall, can also impact air quality.
-
Are there specific areas in Jacksonville with better AQI?
Areas further from major highways, industrial zones, and densely populated urban centers generally experience better air quality.
