Understanding air quality in Raleigh
Raleigh's outdoor air is shaped mainly by traffic ozone, tree pollen, regional transport. 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 Raleigh households on high‑pollution and wildfire‑smoke days — use the free ACH calculator to get the size right.
Outdoor Air in Raleigh Is Hard to Change. Indoor Air Isn't.
The EPA says indoor air can be 2-5x more polluted than outside. For Raleigh residents, the most effective long-term solution is a quality indoor air purifier — removing 90%+ of PM2.5, allergens, and pollutants where you spend most of your time.
