Understanding air quality in Madrid
Madrid's outdoor air is shaped mainly by ground-level ozone, no2 from traffic, saharan dust events. 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 Madrid households on high‑pollution days — use the free ACH calculator to get the size right.
