The ventilation of hoods is an essential element in modern kitchens, whether in homes or professional establishments. It plays a crucial role in maintaining a healthy environment and ensuring kitchen safety.
The components of a hood
A kitchen hood is made up of several key elements. The first component is the canopy, which covers the cooking area and captures smoke and vapors. Next, there are the filters, which trap grease particles and other contaminants. Ventil eco hoods can have metal filters, which require regular cleaning, or activated carbon filters, which need to be replaced periodically.

The motor is another crucial element, as it sucks in contaminated air and directs it outside. Finally, the ventilation ducts allow the evacuation of stale air from the kitchen. Some hoods also feature integrated lighting, providing better visibility while cooking.
The types of hoods
There are mainly two types of hoods: ducted hoods and recirculating hoods. Ducted hoods suck in air and expel it outside the house. They are effective at eliminating odors and smoke but require the installation of a duct for evacuation.

Recirculating hoods, on the other hand, filter contaminated air and return it to the kitchen. They generally use activated carbon filters to absorb odors. Although their installation is simpler, they are less effective than ducted hoods at completely removing air contaminants.
The operation of ventilation
The ventilation process begins when the hood is turned on. The motor creates a vacuum that draws in air laden with smoke, steam, and grease particles. This air first passes through the grease filters, where particles are trapped. In the case of recirculating hoods, the air then goes through the activated carbon filters before being reintroduced into the kitchen.
For ducted hoods, the filtered air is directed to the ventilation ducts and then expelled outside. This process helps maintain optimal air quality in the kitchen, reducing the risks of condensation and mold.
The installation of a hood
The installation of a kitchen hood must be done carefully to ensure its effectiveness. The height at which the hood is installed above the cooking area is crucial. Generally, it should be placed between 65 and 75 centimeters above the cooktop for maximum efficiency.
The choice of motor power depends on the size of the kitchen and the intensity of use. A restaurant kitchen will require a more powerful motor than a home kitchen. It is also important to ensure that the ventilation ducts are properly installed to avoid air leaks.
The maintenance of hoods
Regular maintenance is necessary to ensure the proper functioning of the hood. Grease filters should be cleaned every month to prevent the accumulation of flammable particles. Activated carbon filters should be replaced every six months to maintain effective odor filtration.
The motor and ventilation ducts should also be checked regularly to ensure they are not blocked. An annual professional cleaning is recommended for hoods used in professional kitchens to ensure their optimal performance.
