How to ventilate the room in foggy weather?

When staying at home in foggy days, it is necessary to properly open the window to make indoor air convection, which makes people more comfortable, prevents chest tightness and shortness of breath, and can better maintain indoor air quality.

In addition, people will carry microorganisms and bacteria when they go out and go home, people will exhale carbon dioxide indoors, furniture and decoration will release all kinds of toxic and harmful gases, and smoking and cooking will also produce pollutants. If you don't open the window for ventilation, the content of indoor microorganisms and bacteria will gradually accumulate, even exceeding the outdoor air.

Therefore, it is necessary to open the window for ventilation for a short time in foggy days. The staff of the provincial environmental monitoring station suggested that when the outdoor air pollution is not very serious, you can open the window twice a day for 20 minutes each time under the condition of still wind. But avoid the dust brought by traffic peaks and strong winds in the morning and evening. In case of continuous pollution, wet towels can be hung near the screen window during ventilation, which can play the role of filtration and adsorption.
