Tips to Protect Yourself from Unhealthy Air Quality in Columbus, OH

Avoid outdoor exercise or strenuous activities during high AQI days, especially during peak pollution times in the afternoon. If possible, schedule necessary outdoor tasks for early morning or evening when pollution levels are often lower.

Keep windows and doors closed and use an air purifier with a HEPA filter to reduce indoor air pollution.

Regularly check Columbus's AQI. For "unhealthy" or higher AQI levels, wear an N95 mask outdoors, especially if you're in high-risk groups or sensitive to pollution.

FAQ

Frequently Asked Questions

When is AQI usually the worst in Columbus?

The AQI in Columbus is typically worst during the summer months (June through August) due to high temperatures and sunlight, which contribute to ground-level ozone formation. Occasional temperature inversions during winter can also trap pollutants close to the ground, leading to poorer air quality.
What are common pollutants that impact AQI in Columbus?

The main pollutants affecting Columbus’s AQI are ground-level ozone and fine particulate matter (PM2.5). Ozone forms during hot, sunny days from vehicle emissions and industrial pollutants, while PM2.5 comes from sources like vehicle exhaust, industrial activity, and occasional wildfire smoke from distant regions.
Are there specific areas in Columbus with better AQI?

Suburban neighborhoods on the outskirts of Columbus, particularly those away from major highways and industrial zones, tend to have better air quality. Areas closer to parks and green spaces, like near Highbanks Metro Park or the Scioto River, often experience cleaner air compared to downtown or neighborhoods near busy traffic corridors.
