Dehumidifiers: Meaning, Types and Uses

Looking for a dehumidifier meaning? Types of dehumidifiers and it’s uses? Then you came to the right place.

The first thing that must be done to make good use of dehumidifiers is to choose correctly the one that suits the conditions. It is important to take into account the appropriate size of the dehumidifier , which will depend on the size of the room, so you must have the measurements.

Uses of dehumidifier

Some of the signs that you need a dehumidifier in your home or work environment are as follows:

  • Misty smell: the smell of excess humidity is quite characteristic and is perceived even stronger if the space is very closed . As soon as the smell is perceived, it is important to opt for a dehumidifier to prevent mold, fungi and mites from appearing. A temporary option is to blow dry the moisture using a hair dryer.
  • Presence of mold: when the presence of mold is evident on the walls, ceiling and floor, it is necessary to act immediately, since the increase of it can trigger a wide variety of diseases.
  • Water condensation: this is evidenced by the presence of water in various spaces such as window glass , for this the dehumidifier must be placed to extract all the moisture contained in the air.

What are dehumidifiers?

What are dehumidifiers?

Dehumidifiers are devices that are specifically designed to quickly and very efficiently remove all excess moisture found in the environment , they are generally very easy to install, the price is not so high and the maintenance is not so expensive .

Their operation consists in condensing the moisture that is contained in the air and converting it into water, and then collecting it and evacuating it through the appliance drain . Therefore, this is an excellent option to eliminate this problem in a simple way.

Dehumidifiers are the ideal complement to enjoy a humidity-free environment , in addition they can work in different ways according to the model and system you use. These devices not only remove excess moisture, but are also capable of automatically controlling and maintaining the required moisture percentage , that is, the amount suitable and healthy for human comfort.

In the same way, it was scientifically proven that this type of device is suitable for fighting allergies and helps prevent the proliferation of bacteria and insects such as mites, thanks to this, the spread of diseases and bad smells produced by the insects themselves .

When buying a dehumidifier there are certain aspects that must be taken into account , such as the capacity of the liters that it is capable of extracting and the size of the space in which it is going to be placed.

Household equipment is extremely easy to install , in fact it only needs to be plugged in to start working. These have a tank in which the extracted water is stored and it has a sensor to indicate when it has reached the limit and must be emptied, if not, the device will automatically stop its operation to avoid spills.

On the other hand, if the dehumidifier is for industrial use, it can be installed in two ways: one is for an environment that can be placed on the floor or on the wall and only needs electricity to operate and a pipe for the drain. The other option is for ducts , so the appliance must be installed in the ducts so that dehumidified air can be spread through them.

These kits are great for maintaining a proper balance between temperature and humidity levels . That is why it becomes the perfect ally to maintain a good state of health, especially in regard to the control of respiratory diseases and allergies; likewise, the preservation of home structures and furniture.

Types of dehumidifiers

dehumidifiers meaning, types of dehumidifiers, uses of dehumidifiers,

Dehumidifiers are devices that are responsible for extracting excess humidity from the environment , which are classified by their operation and their use.

According to its operation, you can find those that work based on a compressor and others that do not need it , among them you can find two types: refrigerant dehumidifiers and desiccants:


This type of dehumidifier works with a compressor , which is responsible for sucking the air inside with the help of a fan, filtering it and sending it to an evaporator that works at low temperature with the help of a cooling gel. The operation consists of extracting the water that is in the air, which happens when it passes through the evaporator, as it reaches its dew point, condenses and separates . The water that is extracted is stored in the tank of the appliance or is expelled at once through a drain, it all depends on the model. Finally, the air heats up as it passes through the condenser, returns to its initial temperature and is expelled again to the outside.


This dehumidifier works with the help of a desiccant, which helps to suck the air and sends it to a condenser where the desiccant is located, which absorbs the water.In addition, it has an air circuit in which the desiccant is in charge of drying the same, which helps to completely remove moisture.

However, the classification according to the use of dehumidifiers refers to the area in which it will be placed, this can be for an industrial environment or for exclusive domestic use.

In the case of industrial equipment, they are those that have a high extraction capacity, so these dehumidifiers are of high proportions and can store up to more than a thousand liters per day . On the other hand, those for domestic use are much smaller and have a lower extraction capacity, which reaches up to 35 liters per day, a quantity more than enough for a home or office.

On the other hand, there are home dehumidifiers, which are an extremely inexpensive and sometimes very effective option . Many people use salt as the main person in charge of absorbing humidity from the environment, for this they use a container with salt and a wet bath is made, so that when it dries, it extracts the water from the air.

Also, there is the dehumidifier heat pump which is a type widely used in homes and is considered one of the best ways that exists to eliminate all the water that is in the air.

How are dehumidifiers used?

As mentioned above, dehumidifiers are devices that are responsible for extracting the moisture found in the environment. The use of them will depend on the model and the operation of each one ; It can range from portable for home use to the most extravagant for industrial use.

Also, knowing the storage capacity of the dehumidifier is generally measured in liters per 24 hours. In the same way, identify which functions it has and verify which ones suit your needs , among the most common functions the following stand out:

  • Adjustable hygrostat: helps to control the humidity level inside the room.
  • Integrated hygrometer: it is in charge of analyzing the level of humidity in the room, this is of great help to correctly configure the extraction of water from the dehumidifier.
  • Automatic shut-off: Most dehumidifiers shut off when they reach their storage limit to prevent spills.
  • Automatic Defrost – This helps to automatically melt accumulated frost.

For the correct use of dehumidifiers it is necessary to place it in a place where the air circulates completely around it , some have an air discharge mounted in the upper area and therefore it can be placed against the wall; However, if the dehumidifier does not have this function it is important that then enough space is left around it so that there are no complications.

In the event that you are going to use a hose to drain the water tank, it is important that it be placed on a solid base so that it does not fall; periodically it should be checked to see that it has not moved. Also, keep it away from sources of electrical current to avoid an electrical short.

The dehumidifier should be kept away from dust and areas that generate a lot of dirt.

Before placing the dehumidifier it is important that you read the instruction manual to install it correctly, in the same way it is recommended to previously measure the humidity level with a hygrometer.

The dehumidifier must be connected to an outlet that has a direct connection to earth and when disconnecting it the cord should never be pulled. Regarding maintenance, it must be done periodically to preserve its useful life and follow the instructions in the manual to the letter to avoid causing damage to the equipment during cleaning.
