How does an air cooler work?
An air cooler works on the principle of adiabatic cooling, i.e. by evaporative cooling, also known as hydro-cooling. This is a completely natural process used in industry, allowing companies to reduce the indoor temperature without the need for air conditioning.
The principle is simple: the air cooler captures the warm, dry atmosphere and then propels it through a wet pad. When in contact with air, the water absorbs heat through the mechanism of evaporation. The cooled air is thus obtained by assimilating heat calories in the water before being blown into the room, which results in a cooling of the room temperature and a feeling of well-being.
An air cooler is usually most effective when the room air is dry. However, you must ensure that the room is properly ventilated to avoid saturating the air with moisture. This can be done by opening a window to reduce the humidity level. This is what allows such a device to cool, ventilate and humidify the atmosphere in your home.
How to choose your air cooler?

In order to protect yourself from the heat, we recommend that you check a number of points before buying your air cooler. Whether it's in terms of power or autonomy, it's important that you choosing your air cooler needs your attention.
Airflow
The airflow of a cooler is usually measured in m³ per hour. This is the amount of air your unit can expel in one hour. The greater the flow rate, the greater the blast from your machine. It is therefore obvious that this value highlights the cooling capacity of the equipment.
However, it is essential to be careful when considering the airflow rate and unit capacity of the unit. Even if the cooler you are looking for has a good airflow, it will be less efficient if it has a low power rating. Therefore, the airflow rate should be matched with the power rating of the air cooler.
Sound power
An air cooler consists of a fan and a pump. The combination of these two elements can cause noise pollution, especially when the unit has high speeds. During the day this noise is bearable, but it can quickly become annoying at night.
To avoid disappointment as much as possible, we recommend that you pay close attention to the sound power level when choosing your equipment. If you wish to purchase an air cooler, this criterion should not be set aside, unless you accept the possibility of using your equipment at a considerably reduced speed.
Humidification and ionisation
An air cooler has several functions including :
Air humidification This is achieved through the standard operation of the unit. This is because when the air is captured by the wet pad, the water evaporates and generates fresh air through the absorption of heat. Usually, the wet pad is partly made of ice, so that the atmosphere in your home is properly cooled.
Ionisation Negative ions are created from the electrons that have latched onto the various oxygen molecules in the air. The greater the amount of negative ions in your room, the more positive impacts it has on your health.
The combination of these two functions is quite common nowadays, especially if you want to give your air freshener a boost on the hottest days.
Water tank capacity
Water is an essential element in the operation of an air cooler, as it enables the air in the room to be cooled via the evaporation principle. The capacity of the water tank should not be neglected, as it is the main component of your unit.
The volume of the latter changes depending on the model. This can also affect the humidification or ionisation capability of your cooler. For example, the larger the tank, the longer the cooler will run. In the same sense, it will be more able to lower the temperature effectively.
Contrary to what most people think, we do not recommend looking for a cooler with a huge tank. Depending on the room you want to cool, you may not need a large capacity. For a bedroom, for example, a 2.5 litre tank will be quite sufficient. In a living room, however, you can opt for a 4 to 5 litre tank.
Size and design
On the market, the size of an air cooler can vary from one model to another. Before making your choice, we advise you to check whether the size of your air cooler is suitable for the room you wish to use it in. If the room is relatively small, a compact air cooler will be sufficient. Be careful, however: this criterion has a direct impact on the water tank of the device. The larger the volume of the water tank, the longer the equipment will last.
In terms of design, we advise you to pay attention to the finish and the design materials. The selection of solid, quality materials (hard plastic) is recommended, as this will help you to prolong the life of your machine. You should also choose a product with wheels. This will allow you to move the machine easily from one room to another in your home.
How do I maintain an air cooler?
As with any household appliance, you must ensure maintenance of your air cooler if you want it to remain effective. This will also allow it to function in the long term. However, you should know that such a product requires little maintenance. However, there are certain rules that you need to follow if you want to maintain your device properly.
The water tank
You should regularly empty and clean the water tank of your machine. This will prevent it from accumulating certain mineral and organic particles in the water. For optimal tank maintenance, we recommend using a damp sponge with a small amount of washing-up liquid. Then rinse the tank thoroughly with a jet of water and dry the components before putting them back in place.
Be careful, however, about the water you use to operate your device. It is not recommended to use rainwater to feed the tank. This can lead to the development of certain bacteria. You may even damage your filters and the humidifier pad considerably.
The humidification pad
When you use your air freshener over a long period of time, the water used to humidify or ironise the air in the room can potentially contain a significant amount of limescale. The problem is that this limescale tends to make the humidifier pad stiffer and less absorbent, which reduces its effectiveness.
For this reason, we recommend that you replace the pad as often as possible. This will ensure that the operation of your air cooler is not impaired. Also make sure to rinse it at least once a month with clean water. Finally, if the appliance is not used, avoid leaving the pad in the water tray, as this can lead to mould growth very quickly.
Storage
If you do not intend to use your cooler for a long period of time, you should ensure that the tray is emptied and that the various components of the unit are thoroughly cleaned. It is not advisable to keep standing water in the tray when the machine is not in use.
In fact, mould can quickly develop, which will damage your cooler. We therefore suggest that you store it in a dry, clean and dust-free place. However, if you wish to use it again, you will need to clean it again. The dust will have had time to creep in and foul your product.
