Understanding air quality in Zurich
Zurich's outdoor air is shaped mainly by traffic no2, winter inversions, ozone from precursors. These climb during rush hours and settled, still weather when pollutants aren't dispersed — which is why local authorities monitor them closely and enforce the rules above.
Whatever today's index 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 Zurich households on high‑pollution days — use the free ACH calculator to get the size right.
