What should I do if my home is damp and moldy on rainy days?

Close the doors and windows, and dehumidify with dehumidifier, lime, bamboo charcoal, etc.

When the room is wet, desiccant and activated carbon can be used to prevent moisture and absorb moisture. There are many desiccants specially used for moisture prevention and dehumidification in supermarkets, the most common ones are moisture absorption boxes and dehumidification bags.

Fill a small cloth bag with a proper amount of lime, tie it into a small bag and put it in every corner of the room. Lime itself has the function of moisture absorption and can also slow down the indoor humidity. At the same time, lime also has disinfection function, killing two birds with one stone. Bamboo charcoal dehumidifies and can be used repeatedly.

Buy an air dehumidifier, which, like a vacuum cleaner, can collect moist air, when the moisture turns into water very often.

When the external humidity is high, doors and windows should be closed to prevent moisture and damp. Usually, more windows should be opened for ventilation to reduce indoor water vapor content. Especially in newly renovated houses, the humidity is particularly strong, and more ventilation is needed to eliminate the humidity.
