Model vs measured

We found no measured PM2.5 sensor cell within 25 km of Najafgarh, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.

Wildfire smoke

PM2.5 is forecast to reach 72 µg/m³ in the next 24 hours while NASA satellites detected 200 fire hotspots within 300 km in the last day (nearest about 16 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.

Advice for sensitive groups

At 136, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
