Understanding air quality in Ealing
Ealing is a London borough of around 341,982 people, and like most of the UK its outdoor air quality is driven mainly by local traffic and the weather.
The main local contributors to NO₂ and PM2.5 are A40 Western Avenue, Uxbridge Road (A4020), Heathrow flight path. Levels tend to climb during weekday rush hours and in still, cold spells when pollutants aren't dispersed.
Its status — Focus areas include Uxbridge Road and A40 — means London Borough of Ealing actively monitors and manages air quality in the area.
Whatever today's figure shows on the live monitor above, 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 (use the free ACH calculator below) is the most reliable way to protect Ealing households on high‑pollution days.
