I used to spread some old newspapers at home, but it had little effect. The year before last, Hitachi central air conditioner was installed in my home, which can control both temperature and humidity, and can also automatically monitor air humidity. Temperature and humidity can be accurately controlled all year round, provided that the indoor drainage and ventilation system is perfect and there are no perfect facilities, any method is useless. You can't open the door for ventilation in heavy rain. My house also belongs to that man. It has been popular for some time, and the rooms in my hometown are covered with water stains from floor to ceiling and tiles. After ventilation, it can't be used for several years. It feels good. Pots of shade-tolerant green potted plants, such as chlorophytum, green radish, asparagus, smooth sailing, turtle back bamboo, clematis, sun god, tiger orchid and so on. It can absorb water and purify the air.
If the room humidity is high enough, you can turn on the dehumidification mode of the air conditioner, which can play a certain role. If possible, you can choose a dehumidifier, which can be moved to dehumidify each room. If family circumstances permit, you can buy a dehumidifier. Leave it in the kitchen for a long time. Of course, the cost is higher and the average household electricity consumption will be greater, so the landlord considered it. For kitchen appliances that are used less, put some desiccant to reduce the humidity in the kitchen. For example, baking soda powder and coffee grounds have good dehumidification function and can be made into dehumidification bags.
