How to ventilate and prevent mildew indoors?

The room should be ventilated in time. In the wet season, we should pay attention to controlling the time of opening doors and windows. Usually, we all have the habit of opening the window in the morning. However, this habit is not practical in rainy season. The correct way is not to open doors and windows or to open fewer doors and windows in the morning and evening. If possible, it is best to open all the doors and windows at noon or when the weather is fine, so that the indoor air can circulate and the water can evaporate. 1. Reasonable and scientific ventilation: do not open the window for ventilation when the weather humidity is high, do not open the window for ventilation in thunderstorm weather, and do not open the window for ventilation when the air humidity is the highest at noon to reduce water vapor entering the room. Open the window to ventilate. When the weather is fine in the morning, afternoon or evening and the climate is dry, open the window in time to adjust the indoor air. 2. Use hygroscopic materials: Common hygroscopic articles on the market, such as water absorption boxes and activated carbon, generally take calcium chloride particles as the main component, which have the functions of dehumidification, fragrance, mildew prevention and deodorization. Moisture absorption boxes are mostly used for moisture absorption in wardrobes and shoe cabinets. When you use it, just put it in the cupboard. Quicklime can be wrapped in cloth or sacks and kept indoors to keep the indoor air dry. 3. Remove indoor moisture in time, especially in the bathroom and kitchen, and often use ventilator and ventilator for ventilation. Clean up the stagnant water in the bathroom in time to ensure that the kitchen floor in the bathroom is dry. 4. Try not to dry household clothes in the room. If drying in the closed balcony, pay attention to close the communication door with the room to prevent moisture from entering the room. Indoor plants should be placed on the balcony or living room as far as possible and watered as little as possible. If there is a terrace, try to put it on the terrace.
