What is a dehumidifier?
A dehumidifier is an appliance designed to reduce the level of humidity in the air. Unlike air conditioners, it does not cool or heat the rooms, but works exclusively on humidity, helping to improve living comfort and air quality.
How does a dehumidifier work?
The general operation of a dehumidifier, regardless of its power and capacity, is quite simple:
- Warm air is drawn into the device.
- It passes through a cooling coil that condenses the moisture into water.
- The water is collected in an attached storage tank.
- Drier air is then released back into your home.
Some models also feature a condensate drain pipe, which eliminates the need to manually empty the tank.
Dehumidifier: when to use it
A dehumidifier is recommended in many situations, such as in damp environments like basements, garages or bathrooms without windows, or in homes prone to condensation on windows or mould on walls.
In addition, it can help protect furniture, musical instruments and electronic equipment and, more generally, promotes a healthier environment that is less conducive to the development of dust mites, especially in winter.
Why you should dehumidify your rooms
Using a dehumidifier not only reduces the level of humidity in the air, but also brings a number of additional benefits:
- Prevents the growth of mould and fungi.
- Improves air quality,making it easier to breathe.
- Protects your home and valuables.
- Reduces domestic heating consumption, because drier air heats up more quickly.

How to use a dehumidifier correctly
To get the most out of your dehumidifier, it is important to use it correctly. Position it away from walls and furniture, leaving at least 20-30 cm of space on each side to allow for proper air circulation. Set the desired humidity level (generally around 50-55%) and make sure the tank is empty or connect the hose for continuous condensate drainage, if available.
When the dehumidifier is running, it is advisable to keep doors and windows closed to prevent external humidity from entering. Regular cleaning of the filter is also essential to maintain the efficiency of the appliance and ensure cleaner air.
Many people wonder if it is possible to sleep with the dehumidifier on: the answer is yes, especially if it is a silent model. In fact, a room with the right level of humidity promotes more comfortable sleep and better breathing. When used correctly, it also helps to reduce allergens such as mould and dust mites, making the air healthier. Simply avoid excessive use that brings humidity below 40%, a level that could cause dry mucous membranes or respiratory irritation.

Types of dehumidifiers
When choosing a dehumidifier, a fundamental distinction concerns the installation method. Dehumidifiers can be wall-mounted or portable.
Wall-mounted dehumidifiers are designed for permanent installation, often integrated into the décor or domestic ventilation system. They offer a more discreet appearance and are ideal for those who want a stable, continuous solution without taking up floor space. They are often used in very humid environments, such as bathrooms, laundry rooms or beach houses.
On the contrary, portable dehumidifiers are stand-alone devices equipped with wheels and handles, easily movable from one room to another. This flexibility makes them perfect for occasional use or for those who want to dehumidify different rooms as needed. Furthermore, they only require an electrical outlet and do not need to be installed, making them a practical and immediate choice for most homes.
