Understanding air quality in Marseille
Marseille's outdoor air is shaped mainly by port and cruise-ship emissions, fos-sur-mer petrochemical and steel emissions, traffic no2. 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 Marseille households on high‑pollution days — use the free ACH calculator to get the size right.
