You open the closet and notice an unpleasant smell in the space, one that seeps into the clothes. You check inside and even find mold stains: yes, there is moisture. But how could this have happened? Although it may be due to storing clothes while still damp, the main reason is poor ventilation.

Not only is it annoying day to day, because you can feel the heaviness in the air, but it can also damage the furniture and everything stored inside. So, how do we eliminate moisture from closets? In search of an effective solution, from EL PAÍS Escaparate we have found this pack of 10 Humisafe dehumidifier boxes that, besides being easy to use, can be placed anywhere thanks to their compact design.
How do these dehumidifier boxes work?
Each box contains 280 grams of desiccant granules. These calcium chloride and activated charcoal beads have a high absorption capacity and what they do is capture the water from the environment to prevent it from accumulating inside the closet, preventing condensation and neutralizing bad odors.
As for their operation, it is as simple as removing the lid and the aluminum seal and letting it work. It is important to highlight that they have a paper filter that must not be removed under any circumstances, as it is responsible for retaining the moisture inside the container. To know if it is working, just take a look inside the box: if the beads are hardening, it means they are absorbing moisture.
Designed to prevent leaks
The boxes measure 11.6 x 15 x 8.5 centimeters, so they require little space and can be placed in closets, drawers, or other corners of the house. Another advantage of the design of these dehumidifier boxes is that they are leak-proof thanks to the paper filter, which serves as a protective barrier to prevent spills and staining of clothes.
Additionally, they work between six and twelve weeks, depending on the level of humidity concentrated in the space where the boxes are placed. This is something some buyers appreciate: “I have tried everything and most fall short: after a week they are full and you have to buy another. This one lasts much longer before needing to be replaced, and that really shows in the wallet in a house with constant humidity.”
They do not depend on electricity
Although electric dehumidifiers are also a good option to combat moisture, their energy consumption is noticeable in the wallet. Thus, these boxes present an easy-to-use alternative that does not need to be plugged in to work continuously every day.

“With this, I have managed to get rid of the smell and the feeling of humidity. A lifesaver in every sense,” says one of the users who has tried these dehumidifier boxes at home. They are, therefore, an effective and economical solution and, according to some users on e-commerce platforms, they have a good quality-price ratio. “Since several units come together, you can distribute them in different rooms and it is cheaper than buying individual formats. Capacity and duration, they have given me good results,” adds another buyer.
Frequently asked questions about these dehumidifier boxes
When should the box be replaced?
If the granules have completely dissolved and the water compartment is full, it is time to replace it with another.
Does water accumulate in the boxes?
Yes, in the lower 600-milliliter reservoir.
How many should be placed?
It depends on where you want to place them. A single box is ideal for spaces of four to eight square meters, so if you want to cover larger areas, it is recommended to place several boxes.
