PM2.5: Air Quality Improves Slightly in Bang Rak; Moderate Levels Reported in Din Daeng

The PM2.5 concentrations as of February 14, 2026, in Bangkok slightly improved, with Bang Rak recording a moderate concentration of 35 µg/m 3 compared to the orange levels of 42-52 µg/m 3, which reduced the health hazards facing the locals. Din Daeng remains at a moderate 38 µg/m 3, which is less than the 50 µg/m 3 based on the winds in the dry season that blow dust.

The Pollution Control Department recommends wearing masks outside and not exercising much. Apps such as AirBKK show the situation on the spot. It is an increase after rain foreshadowings, but burns by farmers linger–surveillance over the risky populations in the districts.
