Air quality in Etah right now
Right now the modelled US Air Quality Index for Etah, Uttar Pradesh, India is 152, which falls in the "Unhealthy" band (up to 200). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed.

PM2.5 is 57 µg/m³, 3.8 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 157 µg/m³ against a guideline of 45; ozone is 40 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 17 µg/m³ (below the 24-hour guideline of 25).
Also this hour: desert dust at 196 µg/m³, high enough to haze the sky, carbon monoxide 492 µg/m³.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Etah, 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 94 µg/m³ in the next 24 hours while NASA satellites detected 123 fire hotspots within 300 km in the last day (nearest about 27 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 152, 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.
