When it comes to cooking, the importance of a high-performance kitchen hood cannot be underestimated. An effective extractor hood not only ensures a pleasant and odor-free atmosphere in your kitchen but also contributes to the health and comfort of the entire home by eliminating smoke, grease, and vapors. However, one essential question remains: what power should you choose for a kitchen hood to ensure optimal efficiency?
Determining Factors for the Power of a Hood
To determine the adequate power of a kitchen hood, several essential factors must be considered. These elements directly influence the suction capacity and efficiency of the device in eliminating air pollutants.

- Kitchen Volume: The size of your kitchen is a primary factor. The larger the room, the higher the suction power needs to be to effectively cover the entire area. It is generally recommended to calculate the volume of your kitchen (length x width x height) and multiply this figure by 12 to obtain the power in cubic meters per hour (m³/h).
- Type of Cooking: The types of cooking also influence the choice of power. If you often cook dishes that produce a lot of smoke or steam, such as frying, it is essential to choose a hood with higher suction power.
- Frequency of Use: Intensive use requires a more powerful hood capable of operating efficiently for long periods without overheating or losing performance.
Different Types of Hoods and Their Power
There are several types of kitchen hoods, each with specific capacities and characteristics. Knowing these types will help you make an informed choice based on your needs.
Ventilation hoods, for example, expel stale air outside the house through a duct. They are often more powerful than recirculation hoods because they need to push air over a certain distance.

Recirculation hoods, on the other hand, filter the air using charcoal filters and return the purified air to the kitchen. Although they are generally less powerful, they are popular in apartments where it is difficult to install a ventilation duct.
- Built-in hoods: discreet and integrated into kitchen furniture, they require power suited to the cooking surface.
- Wall hoods: often very efficient, they are mounted against the wall above the cooktop.
- Island hoods: suspended from the ceiling above a central island, they are designed for spacious kitchens and therefore require higher suction power.
How to Calculate the Necessary Power of Your Hood?
To ensure the efficiency of a kitchen hood, it is crucial to correctly calculate the necessary power. Several methods can achieve this, but the most common is to use the volume of the kitchen.
- Calculate the volume of your kitchen by multiplying the length, width, and height of the room (in meters).
- Multiply the obtained volume by the recommended number of air changes per hour (generally 12).
- The result gives the minimum suction power in cubic meters per hour (m³/h) required for your hood.
For example, for a kitchen that is 4 meters long, 3 meters wide, and 2.5 meters high, the volume is 30 m³ (4 x 3 x 2.5). By multiplying by 12, the necessary power is 360 m³/h.
Choosing a Hood Suited to Your Specific Needs
The choice of a hood should also take into account certain practical and aesthetic aspects to perfectly integrate the device into your culinary environment.
It is essential to consider the design of the hood, as it must not only be efficient but also harmonize with your kitchen. Whether you opt for a stainless steel, glass, or aluminum hood, the style should match your preferences.
The ease of maintenance is another important criterion. Hoods with washable metal filters are often more practical. Additionally, regularly cleaning the snail motor ensures optimal operation.
Finally, the noise emitted by the hood is a significant factor. A quiet hood enhances comfort during meal preparation, especially in open spaces.
