Understanding air quality in Charlotte
Charlotte's outdoor air is shaped mainly by traffic ozone from growth, regional ozone transport, tree pollen. These climb during rush hours and settled, still weather when pollutants aren't dispersed — which is why local agencies monitor them closely and enforce the rules above.
Whatever today's AQI shows on the live data, the air inside your home is typically 2–5× more polluted than outdoors, and it's the part you can actually control. Sizing a MERV‑13 or HEPA purifier to your room is the most reliable way to protect Charlotte households on high‑pollution and wildfire‑smoke days — use the free ACH calculator to get the size right.
