Understanding air quality in Austin
Austin's outdoor air is shaped mainly by traffic ozone, mountain cedar pollen, saharan dust. 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 Austin households on high‑pollution and wildfire‑smoke days — use the free ACH calculator to get the size right.
