When the humidity exceeds how much, the house will become very humid.

When the indoor humidity is lower than 20%RH, it is dry, and when it is higher than 80%RH, it is wet.

Prevention and control methods of moisture:

Desiccant and activated carbon can be used. Activated carbon has the function of removing peculiar smell. Besides harmful substances such as in addition to formaldehyde, it can also prevent moisture and absorb moisture. If you want to get better results, it is recommended to buy more. Don't go to the supermarket to buy packaged ones, just buy bulk ones.

There are many desiccants specially used for moisture prevention and dehumidification in the supermarket. The most common types are moisture absorption boxes and bags.

In addition, the dehumidifying bag made of water-absorbent resin and charcoal is more suitable to be placed in narrow spaces, such as closets such as wardrobes and shoe cabinets, and a bag of dehumidifying bag can be hung to discharge moisture.

Put a proper amount of lime in a small cloth bag, tie it into a small bag and put it in every corner of the room. Lime itself has the function of absorbing moisture, and can also slow down the indoor humidity, or find a carton filled with quicklime and put it in an inconspicuous place in the room, killing two birds with one stone.

The principle of buying an air dehumidifier is simple. Just like a vacuum cleaner, it has a bottle, which can collect moist air. When moisture turns into water very often.

The most important period of moistureproof is every morning and evening. The air humidity in these two periods is higher than that at noon. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the house. In addition, if you feel that the doors and windows are closed and the indoor air cannot circulate, it is recommended to open the window for a short time at noon.

Nowadays, the air conditioners used in general families have the function of dehumidification. But it takes two or three hours to adjust the indoor air humidity with air conditioner, and it will make people feel very cold indoors. If you are not satisfied with the dehumidification effect of the air conditioner, you might as well go to the mall to buy a special dehumidifier, which is faster, but consumes more electricity.
