Information
In haze days, we are often told to reduce outdoor activities and close windows at home. So, when the outdoor PM2.5 index explodes, we close the doors and windows to hide indoors. Is the air we breathe safe? What is the PM2.5 concentration?
 
Presumably, this is a question of concern to many young partners, so this time, the manual conducted an experiment on this question to answer the following questions.
 
1. The difference of PM2.5 concentration between indoor and outdoor under the condition of window ventilation.
 
2. The difference between the two when the window is closed and there is no air purification equipment in the room.
 
3. The difference between them when the windows are not completely closed and there is no air cleaning equipment in the room.
