What should I do if the indoor air humidity is high?

1. Intermittent ventilation method. On rainy days, doors and windows facing south or southeast should be closed, and only windows that cannot let in rainwater should be opened to reduce water vapor entering the room. When the weather is good, open windows frequently to ventilate and remove indoor moisture.

2. Indoor heating method. During the rainy season, the house will become damp. Burn a pot of charcoal indoors to increase the indoor temperature. This will remove water vapor and reduce indoor humidity. You must pay attention to ventilation, otherwise the carbon monoxide produced will be harmful to the human body.

3. Lime moisture absorption method. Quicklime can be packed in cloth bags or sacks and placed anywhere in the room to keep the indoor air dry. This method is simple, safe, and easy to obtain materials.

4. Charcoal dehumidification method. Take five to ten kilograms of black charcoal and add water to boil, boil for about ten minutes, then filter out the water and ventilate to dry in the shade, then place it in a breathable container in the corner of the room. Charcoal can be reused after drying in the shade.

5. Ground moisture reversion mitigation method. Close the doors and windows, draw the curtains, and cover the floor with newspapers. After two or three hours, the moisture in the ground will come back up. At this time, put away the newspapers, open the doors and windows to ventilate, let dry air come in, and blow away the moisture, and the room will be much more comfortable.
