Understanding air quality in Barcelona
Barcelona's outdoor air is shaped mainly by port shipping emissions, traffic no2, sea salt aerosols. 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 Barcelona households on high‑pollution days — use the free ACH calculator to get the size right.
