Will opening a window in foggy weather pollute indoor sheets and quilts?

Opening windows in foggy days will pollute indoor sheets and quilts.

Natural ventilation refers to the exchange of indoor and outdoor air through the gap between doors and windows and the external wall. The gap between the open doors and windows and the external wall will become the channel for outdoor particles to enter the room in foggy days. Therefore, closing doors and windows in foggy days is one of the methods to prevent indoor influence in foggy days.

In foggy days, indoor ventilation is very particular. You can't leave the window open or open it blindly, because it will cause more polluted air to enter the room. The best time to open the window in foggy days is noon, because the smog concentration is high in the morning and evening, so avoid opening the window at this time.

If you are a resident near the road, try to open the window as little as possible when the traffic is heavy during the day. Because opening the window at this time will not only bring air pollution, but also bring disturbing noise pollution to the room.

Ventilation method in foggy days

1, open the window for ventilation at the selected time.

When the outdoor smog is relatively less serious, try to avoid morning and evening traffic peaks and windy dust. The best choice is around 12- 14 in the afternoon. Studies have shown that this time is the lowest PM2.5 concentration in a day. At this time, you can open the window twice a day for about half an hour each time.

In addition, hanging wet hair near the screen window, using a humidifier and putting a basin of water around the heating are relatively simple and convenient methods for adsorbing and filtering fine dust.

2. ventilation window with filtering function.

If conditions permit, you can also customize a ventilator with particle filtration function, ventilation window or fresh air system for ventilation, so that purified outdoor air can enter the room and improve indoor air quality.

Step 3 place green plants indoors

When outdoor air pollution is serious, you can plant more green plants with relatively strong adsorption capacity on balconies, terraces and indoors, and try to choose big-leaf plants, because they can not only adsorb a small amount of pollutants such as PM2.5 and formaldehyde, but also increase the oxygen content in the air. Such as green radish, evergreen, tiger orchid, ivy and so on.
