Short answer. Bangladesh's Department of Environment (DoE) publishes a daily Air Quality Index (AQI) report for 26 locations, on a six-level scale from Good (0-50) to Hazardous (301 and above) 1. On 11 November 2026, Dhaka read 137, "Unhealthy for Sensitive Group", driven by PM2.5 1. Phaenyx found no official pollution alert system.

Where can I check air quality right now?

On the DoE website, which posts a Daily Air Quality Index Report the following day 1. The report of 12 November 2026 covered 26 locations, from Dhaka and Chattogram to Cox's Bazar, Rampal and Shyamnagar, each with its AQI, the pollutant responsible and the category 1. Dhaka's value is the average of 3 CAMS and 2 C-CAMS monitoring stations 1.

What do the index levels mean?

The AQI Scheme for Bangladesh 1:

AQI Level of health concern Colour
0-50 Good Green
51-100 Moderate Yellow
101-150 Unhealthy for Sensitive Group Orange
151-200 Unhealthy Red
201-300 Very Unhealthy Purple
301+ Hazardous Maroon

The DoE report gives no official advice per level. For what each level usually means, see Air quality index explained.

How polluted is the air on average?

Very. The population-weighted median of Bangladeshi cities shows about 77 µg/m³ of PM2.5 (annual mean 2021-2023) 2, more than fifteen times the WHO guideline of 5 µg/m³ 3. Nitrogen dioxide is about 22.8 µg/m³ 4, above the WHO guideline of 10 µg/m³ 3. That NO2 figure is a regional background over roughly 80 km: a busy street in Dhaka will be higher.

What should I do on a bad air day?

Phaenyx found no official Bangladeshi advice per AQI level and no national pollution alert. For an earthquake, the Department of Disaster Management asks households to keep a dust mask at home 5. Read A clean-air room at home, Masks for smoke, Pollution episodes, Sensitive people and polluted air and Children and polluted air. A household plan can note who at home is sensitive to polluted air.
