Report from Bang-na area, on the 24th floor building.
AirVisual’s AQI 161 which is indicated as ‘Unhealthy’ and I found that on this height I feel much more air pollution than the ground.

Suggestion:

1. Get yourself and your family managed
2. Avoid outdoor activity
3. Close the door (but I do feel even the door close the air is not clean)
4. Get the PM 2.5 mask, ware the glasses.
5. Get the air purifier
6. Do something with your air condition filter, your car too
7. Take care your child.
