9 Easy Dehumidification Methods

What are some ways to dehumidify a room? Here, we will introduce dehumidification methods using home appliances and dehumidification methods that can be done using familiar items.

Dehumidification method Use an air conditioner

Use the dehumidification function of the air conditioner to keep the humidity of the whole room constant. Air conditioners are installed in most homes, so you don’t need to buy new ones for dehumidification. It costs electricity, but it is the most efficient and easy way to dehumidify. In addition to the dehumidification mode, you can also adjust the humidity in the room by cooling.

Dehumidification method Use a dehumidifier

Similar to air conditioners, dehumidifiers are home appliances that efficiently help maintain a constant humidity in a room. Dehumidifiers tend to use less electricity than air conditioners. In addition to the dehumidification function, many dehumidifiers have air cleaning and ion generation functions, so it is convenient to use other functions.

Dehumidification method Open the window

Even if you don’t rely on home appliances such as air conditioners and dehumidifiers, you can easily dehumidify just by opening the window and letting the moisture escape from the room. However, the dehumidification method by opening the window is effective only when the outside air is dry. Even if you open the window to ventilate the room during the humid rainy season, the humidity in the room will not decrease.

In addition, it is necessary to devise how to open the window, and open at least one window diagonally in order to efficiently release moisture-laden air outside. If the wind does not come in from the window, it is recommended to open the window and install a fan in front of it to move the air in the room.

Dehumidification method Use a dehumidifier

Dehumidifying agents are suitable for efficiently dehumidifying narrow spaces such as closets and closets. One dehumidifier is enough for a small storage space, but one dehumidifier is not enough for the whole room, so prepare several.

Dehumidification method Use newspaper

You can easily dehumidify by simply rolling up newspaper and placing it in the room. Newspaper is a suitable item for dehumidification because the fibers of the newspaper are rough and it easily absorbs moisture in the empty gaps. When drying indoors, if you roll the laundry under the drying rack, the laundry will dry, and the moisture from the laundry will be absorbed, so the humidity will not increase. In addition, it is recommended to stuff newspaper inside the shoes to dehumidify the geta cupboard, where moisture tends to accumulate.

Dehumidification method Use a frozen PET bottle

PET bottles filled with water and frozen are also familiar items that are useful when you want to easily dehumidify. Moist air is cooled by the frozen PET bottle and becomes water, so when you leave it in the room, place the PET bottle on top of the saucer. Also, if you use a fan with a frozen plastic bottle, it will cool a lot of the air that contains moisture, and you can effectively dehumidify it.

Dehumidification method Use baking soda

Baking soda is used as a convenient cleaning product, but baking soda can also be used for dehumidification. The dehumidification method using baking soda is as simple as putting baking soda in a container such as a glass bottle and placing it in a place where you are concerned about moisture.

Baking soda also has a deodorizing effect. Therefore, it is recommended for shoe cupboards and closets that are concerned about odors. Baking soda hardens when it absorbs moisture, so when it hardens, it’s time to replace it. Baking soda used for dehumidification can be reused for cleaning afterwards, so it can be used without waste.

It is also recommended to transform baking soda into an air freshener using aroma oil and place it in the room to dehumidify it.

Dehumidification method Use charcoal

Many people know that charcoal has a deodorizing effect. In addition, charcoal has countless holes, so it is an item suitable for dehumidification because it easily absorbs moisture. After dehumidifying with charcoal, it can be reused by drying and removing the moisture, so it can be used repeatedly. Charcoal can be made from wood or bamboo, but stylish charcoal that can be used as interior decoration is sold, so check it out.

Dehumidification method Use coffee grounds after use

The powder that remains after extracting coffee also has a dehumidifying effect and is convenient because it can be reused. If you often drink drip coffee, don’t throw away the coffee grounds, dry them and use them for dehumidification. It takes some time to dry the coffee grounds, but once it’s dry, it’s as easy as putting it in a container and placing it in the area you want to dehumidify. It also has a deodorizing effect, so it can be used in places where odors are a concern.

Causes of high humidity

Why is the humidity in the room so high? Here are some of the possible causes of high humidity in a room.


Humidity is high in all regions during the rainy season. Humidity will be high throughout the year, especially in areas with a lot of rain. Also, if the terrain is prone to moisture buildup, the humidity will be higher than in other areas. In addition, winter is a dry season, but the large temperature difference between the outside and inside makes it easy for condensation to form on the window glass. Condensation in winter concentrates moisture on the window glass and causes mold to occur, so be careful of condensation in winter.

indoor drying

On rainy days or in the winter when it is difficult to dry the laundry, many people hang it in the bathroom or in the room. Drying laundry that contains a lot of moisture indoors will increase the humidity in the air when it dries.

due to poor ventilation

The bathroom is the place with the highest humidity. If you leave the bathroom door open after getting out of the bath without ventilating the bathroom, the humidity in the dressing room and room will rise at once. Open the windows and ventilate the bathroom to let the moisture out of the bathroom.

What happens if you don’t dehumidify

What happens when the humidity in the room is kept high? Here, we will introduce possible problems such as problems caused by insufficient dehumidification.

Growth of mites and mold

High humidity conditions are the perfect environment for mites and molds and help them to develop and grow. Be aware that living in a room with dust mites and mold can cause allergic reactions and physical discomfort, which can lead to health problems.

Especially if the humidity is over 60% for a long time, the growth speed of mites and mold will increase, so be careful.

building decay

Wooden buildings will rot if left in damp conditions for a long period of time. Be aware that even in a newly built house, the pillars may rot due to humidity, and you may need to renovate or rebuild as soon as possible.

half-dried laundry

Even if the laundry is dried indoors in a room with high humidity, it will not dry for a long time. If the wet laundry does not dry, even the cleanly washed clothes will be half-dried, leaving an unpleasant odor on the clothes. The half-dried smell is also a sign that bacteria are breeding, so you will need to wash it again, which will be a hassle.

physical ailment

If you spend time in a room with high humidity, you will experience physical discomfort such as discomfort and sluggishness. Be aware that humidity can cause mold and dust mites, which can cause allergies and atopic dermatitis.

Another thing to watch out for is heat stroke. If you stay in a room with high humidity for a long time during the hot summer months, your sweat won’t evaporate properly and the heat will stay inside your body, increasing the risk of heat stroke. In the worst case, heat stroke can be fatal, so be careful.


Maintaining the optimum humidity in a room is important for living a comfortable life and maintaining physical health. This time, we introduced how to dehumidify using various items, so let’s try it in a place where humidity tends to be high.
