How to choose your moisture absorber

It is important to choose the right humidity absorber. Indeed, it improves the quality of the air in a room. Here are the criteria to take into account when buying:

#1 - The surface of the room

The size of the room is the first criterion to consider when buying a moisture absorber. You can't use the same moisture absorber to dehumidify a 35-square-meter living room and a 5-square-meter walk-in closet, because they don't have the same area. So you need to buy the one that suits the size of the room for the absorption process to be efficient. You should also not abuse it and take the one that is intended for spaces larger than yours, otherwise you risk drying out the air in the room too much.

#2 - The level of the tank

The filling condition of the moisture absorber tank should be checked regularly. But on some opaque models, it is impossible to know this level of the tank without doing a little disassembly. It would be better to choose those with a completely transparent tank and also composed of a level indicator to avoid this kind of inconvenience.

#3 - The type of refill

The moisture absorbers use an absorbent cartridge that must be replaced once it is no longer effective. The type of cartridge varies from one absorber to another. There are 3 types of absorber refills: crystal bags, pellets, mineral salt pebbles or tablets. The bags of crystal absorbers contain a very irritating substance for the skin. You must handle them with great care when replacing them.

Mineral tablets or pebbles melt completely when they are no longer effective and should be flushed down the toilet. The gel technology absorber sachets are the most interesting, as they present less risk of contact with the skin when you place them in the device.

#4 - The stability and circulation grid

Generally speaking, the elements that make up moisture absorbers turn into liquid and will be received in a tray. This liquid can easily spill out if the device is not properly stable. Therefore, moisture absorbers with an anti-spill feature are preferred if you have a child or pet.

#5 - The tank drain plug

Some moisture absorbers have a drain plug on the tank. This feature helps prevent splashing. Therefore, you can opt for a model with this feature for safer use.

How to use a moisture absorber effectively?

Whether in winter or summer, increased humidity can always be unpleasant. Only the use of a moisture absorber is the safest way to remedy this. Indeed, with humidity, mold can grow quickly, especially in the corners. Thus, you need to know the most effective way to use a moisture absorber effectively in every area.


Using a moisture absorber in the home
You have the choice of placing this device in any room of your home (kitchen, bathroom, bedroom). But it's best to place it where excess moisture or stubborn odors are very present. For example, you can put it in storage closets to protect your clothes.

If you put it in a room that has a large surface area, you should replace it as often as possible. For disposable (crystal bag) moisture absorbers, just throw them away when they are full and replace them. While for the refillable models that are composed by pellet pebbles or mineral salts, you need to regularly empty the water that is collected in the tray.

The use of a moisture absorber in a car

Always try to place it in a location where it won't tip over when your car is in motion. While your car is not in use, close all windows as well as the sunroof to more effectively control moisture.

However, a disposable moisture absorber controls moisture in a car better. You can simply put them under the seats. And as mentioned above, when the crystals run out, just throw them away. However, keep in mind that moisture absorbers cannot remove standing water, only moisture from the air. Thus, it is important to absorb some excess water with a vacuum cleaner before using a moisture absorber. You should also keep them out of reach of children and pets.


The different types of moisture absorbers

Not all moisture absorbers have the same components. They may use different materials to improve air quality. These may include clay, silica gel or sodium chloride.

Clay moisture absorber

Clay has a good property of absorbing large amounts of moisture in a house. It can also release air when it is dry. Besides, the clay moisture absorber acts as a real natural deodorizer. It can neutralize most odors in the home, even tobacco.


  • Practical to avoid mirror or glass fogging.
  • Ecological material for the habitat.
  • Improves the general air quality in a room.


  • Not suitable for high humidity areas.
  • Low moisture absorption capacity compared to other absorbers.
  • Slow acting

Silica gel moisture absorber

It is a moisture absorber made from sodium silicate. Usually made in the form of a pearl, silica immediately absorbs moisture in a room. In fact, it acts by retaining moisture up to more than 30% of its weight. All silica beads are made up of small pores that facilitate the absorption of moisture.


  • Good absorption capacity.
  • Can be reused several times
  • Longer shelf life compared to others.


  • Only practical for products to be placed at room temperature.
  • Toxic substance (that's why manufacturers always put a warning on the packaging).
  • Expensive (so it can't be placed anywhere in the house).

Calcium chloride absorber

Ideal for kitchens, basements and other larger rooms, a calcium chloride moisture absorber is also very effective. Formed by a mixture of chlorine and calcium, it is convenient for keeping goods dry while in transit. Alternatively, to have the same effect as calcium chlorides, gem salts can be used.


  • Preserves the environment
  • Dries the air well after a few hours
  • Prevents the re-evaporation of humidity in the air


  • Can cause sore throat
  • Very irritating material
  • Must be changed regularly

Humidity absorber or dehumidifier?

Moisture Absorber

Many people turn to a moisture absorber. It is both affordable and easy to use. It requires neither an electrical connection nor a particular installation. Composed of a plastic tray, a cartridge that has the role of absorbing moisture from the air, and a tray to collect water, it is enough to place it in the room to be treated so that it can perform its function.

However, its dehumidification process is very slow. It also has a difficulty to significantly reduce the humidity level of a room. Besides, its absorbent bag has only a capacity of 1 to 2 L of water and must be replaced every 2 to 3 months. This means that you have to spend extra money. The contents of this bag also prove to be harmful to your eyes and skin. The moisture absorber is usually only suitable for small spaces.


The dehumidifier is a household appliance designed to remove moisture from a room. It has a fan whose function is to draw in humid air. It then passes it through a low temperature evaporator to retain only the moisture. It is only the dry air that will be rejected in the room. The dehumidifier is faster and more efficient than the humidity absorber. In addition, it does not need to be recharged to operate.

A dehumidifier, on the other hand, will require an electrical source at all times. This can cause your electricity bill to skyrocket. In addition, it is bulky, unless you opt for a mini dehumidifier. It is also a noisy device. Indeed, it is equipped with the same condensation system as a refrigerator, and necessarily emits a certain volume. Finally, a dehumidifier generally costs 4 times more than a humidity absorber.


The choice between a moisture absorber and a dehumidifier depends on your preference. Choose the former if you are looking for a simple and affordable solution. The latter is more complicated and expensive, as it requires a power source all the time. But it is more effective.

Why buy a moisture absorber?

Helps manage moisture

The humidity absorber is one of the most practical solutions to control excess humidity in your home. With this device, the ambient air will be more pleasant and the humidity level will be healthy. In addition, paint and wallpaper will not peel off, as this device balances the indoor humidity.

To stop the formation of mold

All kinds of rot are often the undesirable effects of excess moisture in a room. By placing a moisture absorber in the room, you can considerably reduce the humidity in the air and thus prevent the development of microscopic fungi.

Optimized well-being

High humidity can have an unpleasant effect on your family's well-being. It can make your home feel cold or cause musty odors. The humidity absorber helps to make the air in a room more pleasant to breathe.

A way to protect personal property

The walls of your home aren't the only ones that suffer from the effects of moisture. Your important personal belongings (clothes, books, furniture...) as well as certain foods can also fall victim to its aggression. The humidity absorber is the solution to keep them in good condition and avoid their possible moulds.

A different way to scent your home
Moisture absorbers do more than just reduce excess humidity in the air. They can also eliminate unpleasant odors. Some even use refills that diffuse floral, wood and other scents. They create a special atmosphere in your home.

As traditional dehumidifiers are often made with calcium chloride to capture moisture from the air. These substances are dangerous to have in your home and can cause harm to people, pets. So it's best to throw it away from right after use.
