How Does a Kitchen Extractor Hood Work?

Transform your kitchen into a spotless space with the invisible magic of extractor hoods. These modern home essentials not only dissipate smoke, neutralise odours and capture grease particles generated when cooking, but they also improve air quality, creating a healthier and more pleasant environment. Despite their everyday use, few people really understand how they work or how crucial it is to choose the right hood for their kitchen.

In this article, we will explore in detail How a kitchen extractor hood works, the different types available on the market, and the key factors you should consider when choosing one for your home. If you're looking to improve the efficiency of your kitchen and ensure a cleaner environment, read on to find out everything you need to know about this indispensable appliance.

What is an Extractor Hood?

Before understanding how a kitchen extractor hood works, it is important to understand the nature of this tool. An extractor hood is a ventilation device specifically designed to remove smoke, fumes, odors, and grease particles generated during the cooking process. This appliance is usually installed above the stove or cooktop and acts as a barrier that prevents these contaminants from dispersing throughout the kitchen and the rest of the home.

Extractor hoods are essential for maintaining a clean and safe kitchen environment, especially in kitchens that lack adequate natural ventilation. As well as improving air quality, they help protect furniture, walls and ceilings from the build-up of grease and dirt, which also helps to prolong the life of the kitchen and reduce the need for deep cleaning.

How Does an Extractor Hood Work?

Understand How a kitchen extractor hood works is key to appreciating its role in maintaining a clean and healthy environment. In simple terms, a range hood uses a ventilation system that can operate in two ways: by extraction or by recirculation.

1. Extraction: In this mode, the hood draws in polluted air and expels it outside the home through a duct. This process ensures that stale air, loaded with odours and particles, is completely removed from the interior of the house.
2. Recirculation: In the case of hoods without ventilation ducts to the outside, recirculation mode is used. Here, the hood draws in dirty air, filters it through a filter system (usually activated carbon for odours and metal for grease), and then returns it clean to the environment.

In addition to these two operating modes, the extractor hoods are equipped with lights that improve visibility during cooking and controls that allow the ventilation speed to be adjusted as needed.

What are the types of extractor hoods?

To better understand How a kitchen extractor hood works, it is useful to know the different types available on the market. Each type is designed to suit different kitchen styles, ventilation needs and aesthetic preferences. Below are the most common types of extractor hoods:

Wall Mounted Extractor Hoods:
They are a popular choice in kitchens where the cooktop is situated against a wall. They often have a slanted or T-shaped design, giving them a sleek, modern look. Wall-mounted hoods can operate in either extraction or recirculation mode, depending on the installation.

Island Extractor Hoods:
In addition to their practical function, they are often a focal point in the kitchen due to their central location and aesthetic design. Like wall hoods, they can operate in extraction or recirculation mode.

Integrated Extractor Hoods:
They are an excellent option for those looking for a discreet and minimalist appearance, as they are almost hidden from view. Although they are less visible, they offer the same effectiveness in extracting or recirculating air.

Countertop Extractor Hoods:
They are ideal for kitchens with an ultra-modern design and where you want to maximize the free space above the stove. They operate in recirculation mode and are less common than other types of hoods.

Decorative Extractor Hoods:
They often have finishes and shapes that make them a design element within the kitchen. They are suitable for those who want a hood that not only fulfills its ventilation function, but also improves the overall aesthetics of the space.

How to Choose an Extractor Hood?

Choosing the right extractor hood for your kitchen is an important decision that will depend on several factors. By understanding How a kitchen extractor hood works and the different types available, you will be better prepared to make the best decision. Here are the key aspects to consider when choosing a range hood:

• Ease of Maintenance: Extractor hoods require regular maintenance, such as cleaning the filters and the exterior surface. Opt for models that offer easy access to the filters and are easy to clean.
• Installation Type: Evaluate your kitchen layout to determine what type of hood will best fit. If your stove is against a wall, a wall-mounted hood will be a logical choice. If it's on a central island, an island hood will be more appropriate.
• Size and Power: It is crucial that the extractor hood is the right size for your stove and has enough power to handle the amount of smoke and fumes generated during cooking. As a general rule, the hood should be at least as wide as the stove.
• Operating Modes: Consider whether you prefer a hood that operates in extraction or recirculation mode. If your kitchen has access to an outside air vent, choose an extraction hood for the greatest efficiency.
• Noise Level: Extractor hoods can generate a significant level of noise, especially at high speeds. When choosing a hood, check the decibel (dB) level and opt for one that offers a good balance between power and noise.

How to Install an Extractor Hood?

Now that you understand how a cooker hood works, it's time to think about installing it. Although some models may require the help of a professional, many can be installed by the user themselves with the right tools and knowledge. Below, we offer a basic guide to installing a cooker hood:

1. Space Preparation:
   • Measurement: Before you begin, measure the space where the hood will be installed to ensure there is enough room for the selected model. The hood should be located between 65 and 75 cm above the stove to ensure efficient ventilation.
   • Ventilation Duct Cut: If your hood will operate in exhaust mode, you will need to cut a hole in the wall or ceiling for the vent that will carry the air outside. Make sure the hole is aligned with the hood's air outlet.
2. Mounting the Bracket:
   • Wall or Ceiling Mounting: Depending on the type of hood (wall-mounted, island-mounted, or built-in), you will need to fix the bracket to the wall or ceiling. Use a level to ensure that the hood is straight. Mark the fixing points, drill the holes, and insert the appropriate screws and plugs to secure the structure.
3. Vent Duct Connection:
   • Duct Adjustment: Connect the vent duct to the hood's air outlet. Use a metal clamp or tape to secure the duct and prevent air leaks. Make sure the duct is well insulated to prevent the loss of hot or cold air, which could affect the hood's efficiency.
4. Electrical Connection:
   • Power Cables: Connect the extractor hood to the mains power supply in your home. If the model requires it, make sure it is connected to a grounded socket. If you do not feel comfortable making electrical connections, it is advisable to hire a certified electrician.
5. Mounting the Bell:
   • Final Fixation: Once the bracket, vent, and electrical connections are in place, mount the range hood in its final position. Make sure it is securely fastened and test all functions to confirm that it is working properly.
6. Testing and Adjustments:
   • Power On and Check: Turn on the hood and check that the air is being properly extracted or recirculated, depending on the type of installation. Also check the lights and controls to make sure everything is working as expected.

While these steps provide a general guide, it is always advisable to follow the specific instructions from the manufacturer of the hood you are installing.
