In a properly ventilated and heated home, the use of a dehumidifier is completely unnecessary. However, it is not uncommon for our insulation to be imperfect and to require action on our part.
To alleviate this problem, the installation of a dehumidifier is recommended to regulate the humidity in a room and create inhospitable living conditions for allergenic organisms such as dust mites and moulds.

Smaller spaces are generally conducive to moisture accumulation and therefore to the development of mould. To limit these condensation problems, we have selected 3 moisture absorbers that are perfectly suited for your wardrobe, your cellar or your car. For more information >> The best car dehumidifiers.
Wessper car dehumidifier and defroster
The best performer according to consumers
The Wessper is a mobile moisture absorber specially designed for condensation problems. Ideal for small spaces without heating, it prevents the appearance of mould in your car or caravan. Made from silica gel, the product lasts for approximately 3 months and can be reused after drying the bag in the radiator or microwave.
Carlinea dehumidifier and fogger
Our favourite ❤
The Carlinea is ideal if you want to remove moisture from your vehicle. This reusable product is made from silica gel to reduce fogging and condensation caused by excess humidity and poor ventilation.
This mobile moisture absorber is cold and heat resistant and holds water safely and without leaks. The product's plus? The Carlinea is equipped with a blue indicator. As soon as it turns pink, place the bag in the microwave for 6 minutes to remove the absorbed moisture. The indicator will then turn blue again and the bag will be usable again.
Rubson Sensation Pure moisture absorber
An interesting price/quality ratio
The Rubson sensation pure is a discreet and portable humidity absorber for small rooms of 10 m². Ideal for a small area such as a car, it effectively combats your moisture problems, while preventing the appearance of mould and odours. Compact and design, it has a long life span (about 2 months for 10 m²) and an affordable price thanks to the long life of its chemical cartridge.
What are our selection criteria?
Excessive humidity in your home is conducive to the growth of dust mites and mould. These nuisances can affect your health and comfort. In order to eliminate these problems, we believe it is important to choose the right dehumidifier: a device that is too small can be ineffective in reducing relative humidity, while a professional (oversized) device can dry out the air too much.
Our decision is based on the practicality of dehumidifiers (water discharge, size, operating mode, moisture absorption capacity, room temperature, noise level, fan speeds and price), but also on the room to be dehumidified: for example, a bedroom does not require as much power as a cellar or basement to be dehumidified.
Our only constraint is to inform you without distorting reality!

How does a dehumidifier work?
A dehumidifier works in a similar way to an air conditioner: it sucks in air, filters the moisture and returns it to the room. In general, the moisture collected by these products is collected in a tray that must then be emptied. To date, there are no less than four different techniques for collecting room humidity:
- The moisture absorber A moisture absorber is a mobile container containing calcium-based mineral salts. Presented in the form of a filter, a chemical cartridge or a tablet, its mineral salts absorb moisture from the air and transform it into water, which is then collected in a container. Suitable for use in unheated spaces, this product is generally available at a low price. To find out more, read our article : how to use a moisture absorber?
- The compressor Compressor dehumidifiers, like your air conditioner, use a refrigerant gas to cool a condenser to dry the air. As the humid air comes into contact with the condenser, it changes into water and is collected in the tank. This dehumidification system is simple and fast, but relatively noisy and energy consuming.
- The desiccant Desiccant dehumidifiers are recommended for drying air at low temperatures. The humid air is sucked in by a fan and then subjected to a desiccant wheel made of a porous solid. Under its effect, the moisture returns to its liquid state and is then blown onto a metal plate by a second fan blowing hot, dry air.
- The Peltier effect It is associated with a physical phenomenon known as the thermoelectric effect. The Peltier effect is manifested in the form of a heat shift induced by the presence of an electric current. This phenomenon was discovered in 1834 by the French physicist Jean-Charles Peltier, who connected the ends of a bismuth wire to an accumulator using two copper wires. In this experiment, he observed that one of the copper/bismuth junctions heated up while the other cooled down.
How do I set up my dehumidifier?
Most dehumidifiers are easy to adjust thanks to their intuitive control panel. Here are the main steps if you want to install/adjust your dehumidification system:
- Choose the right location Installation of your dehumidifier in the right place will affect its use and efficiency. The product should not be placed too close to the wall to facilitate air ventilation. Also, if your living space allows, try to position it in the centre of the room or near the windows. This will make it easier for the hygrostat in your unit to detect changes in humidity resulting from too much heat or too little temperature.
- Set the humidity level to 45 % Humidity: We suggest that you set your humidistat to a humidity level of 45-50 %. You can adjust this according to your level of indoor comfort, but remember that this is the ideal humidity level for good indoor air quality. Too low a humidity level can lead to health problems (lung irritation, chapped lips, etc.), while humid conditions will be conducive to the growth of moulds and other allergens.
- Check the water drain Once your dehumidifier has been set up, you must ensure that it is properly installed at the water outlet. If your appliance does not have a removable tray, you can connect it to a floor drain. The use of a drain hose will be very useful for this purpose. Otherwise, remember to drain it manually on a regular basis.
- Save energy with the timer You can reduce the cost of your energy bill by only running your dehumidifier at specific times (or when you are drying your clothes). Note, however, that it is advisable to run your dehumidifier frequently (every day) to avoid excess humidity in your home.
- Set up the Wi-Fi function Humidity monitoring: you can monitor your humidity level from your smartphone by purchasing a professional wifi enabled dehumidifier. Don't forget to configure this function if your equipment allows it.
How to fight against humidity?
In addition to a dehumidifier, there are some simple things you can do to help reduce the humidity in your home and breathe easier. Here are some of them:
- Open the windows The most natural way to dehumidify a room is to open the windows. This simple action allows fresh air to enter and improves the air circulation in the room.
- Think about plants They have a natural tendency to absorb moisture. Their absorption capacity is low, but they will help you to clean up your home. They include: peace lily, lounge palm, English ivy, tillandsia and Boston fern.
- Take cooler showers Hot showers are known to increase the humidity level in your home. To avoid this problem, try using cooler water while keeping the bathroom door open to increase air circulation. This will keep condensation to a minimum.
- Turn on the cooker hood When heating water, cover the pots and turn on the kitchen hood to remove moisture from the house.
- Check your air vents If these are blocked by a cloth, the humid air will not be able to escape properly. Maintain or reinstate the ventilation grilles at the bottom for the air inlet and at the top for the air outlet.
