The Ultimate Buying Guide for Cooker Hoods

What is the purpose of a cooker hood?

What is the difference between extraction and recirculation

Extraction and recirculation are two different methods used in cooker hoods to deal with the airflow generated during cooking.

Is extraction better than recirculation?

Yes, extraction is generally better than recirculation. Extraction systems expel the cooking odours, smoke, and moisture completely out of the kitchen through external ducting. Recirculation, on the other hand, filters the air and then releases it back into the kitchen. While extraction provides more efficient air clearance, recirculation can be useful in situations where external venting isn't possible.

Do recirculating extractor fans remove moisture?

No, recirculating extractor fans do not effectively remove moisture. They primarily focus on removing odours and some particles from the air through filters. Moisture is usually recirculated back into the room. Only an extraction system can efficiently remove moisture by venting it outside.

In summary, extraction hoods remove air from the kitchen and exhaust it outside, while recirculation hoods filter the air and release it back into the room. The choice between the two depends on factors such as kitchen layout, feasibility of duct installation, and the desired level of air purification.

What's the right height for a cooker hood away from the hob?

For electric hobs, the minimum recommended distance between the hob and the cooker hood is 600mm (around 24 inches). For gas hobs, it's 750mm (around 30 inches). However, always consult the manufacturer's guidelines as some models may have specific requirements.

Styles and Types of Cooker Hoods

Chimney Cooker Hoods: Chimney cooker hoods feature a vertical chimney-like structure that extends from the hood, providing a stylish and prominent focal point in the kitchen. They are typically mounted on the wall above the cooking area and are known for their excellent extraction capabilities.

Curved Glass Cooker Hoods: Curved glass cooker hoods offer a sleek and contemporary design with a curved glass canopy. They are often wall-mounted and provide efficient extraction while adding a touch of elegance to the kitchen.

Angled Glass Cooker Hoods: Angled glass cooker hoods feature a sloping glass canopy that adds a modern and unique look to the kitchen. They are designed to be mounted on the wall at an angle, providing both style and functionality.

Visor Cooker Hoods: Visor cooker hoods are compact and practical, commonly found in smaller kitchens or above hob units. They have a visor-like design that can be pulled out or adjusted when needed, offering extraction and lighting in a convenient package.

Flat Glass Cooker Hoods: Flat glass cooker hoods are characterised by a flat glass surface that covers the extraction unit. They are sleek, minimalistic, and often integrated into the kitchen cabinetry for a seamless look.

Integrated and Canopy Cooker Hoods: Integrated cooker hoods are concealed within kitchen cabinetry, providing a seamless and discreet appearance. Canopy cooker hoods, on the other hand, are integrated into a canopy or overhead structure, blending with the kitchen design while providing effective extraction.

Island Cooker Hoods: Island cooker hoods are specifically designed for kitchens with a central cooking island. They are suspended from the ceiling and provide extraction over the cooktop, ensuring efficient ventilation in open-plan kitchen spaces.

Ceiling Cooker Hoods: Ceiling cooker hoods are built into the ceiling, offering a space-saving solution while providing effective extraction. They are ideal for kitchens where wall space is limited or when a sleek, minimalist design is desired.

Downdraft Cooker Hoods: Downdraft cooker hoods are unique in that they are integrated into the countertop or behind the cooktop. When in use, they rise up from the surface to extract cooking fumes and then retract back down when not needed, creating a clean and unobstructed view in the kitchen.

Vented Induction Hobs: Vented induction hobs combine the functionalities of a hob and cooker hood into a single unit. These hobs have integrated extraction systems that draw cooking fumes directly from the cookware, making them an efficient and space-saving option.

Designer Cooker Hoods: Designer cooker hoods are characterised by their artistic and eye-catching designs. They come in various shapes, materials, and finishes, allowing homeowners to make a bold statement in their kitchen while ensuring effective ventilation. These hoods often prioritise style and aesthetics without compromising on functionality.

How to choose the best cooker hood for your kitchen

Do you have a suitable outside wall to install ducting?

Once you have identified a suitable outside wall, you can hire a professional installer or consult a contractor to assess the feasibility of ducting installation in your kitchen. They can guide you through the process, ensuring that the ducting is properly installed and meets all safety and ventilation requirements.

Does a cooker hood need to be the same size as the cooker?

Ideally, yes. The cooker hood should be at least the same width as the cooker or hob below to ensure efficient extraction of steam, odours, and smoke. In fact, a slightly larger cooker hood than the cooker can be even more effective, as it ensures that all emissions from the cooking process are captured.

What extraction rate do you need?

What about smart cooker hoods

Smart cooker hoods are technologically advanced kitchen appliances that offer convenience and functionality. With built-in sensors and connectivity features, they can automatically adjust the extraction rate based on cooking activity. Smart controls allow remote operation through smartphones or integration with smart home systems. These hoods provide an efficient and modern solution for ventilation in the kitchen.

Cooker hood noise levels

When considering cooker hoodnoise levels, here are some important factors to keep in mind:

1. Decibel (dB) Rating: Look for the decibel rating of the cooker hood, which indicates the noise level it produces. Lower dB ratings indicate quieter operation. Aim for a cooker hood with a low dB rating to minimise noise disturbance in your kitchen.

2. Fan Speeds: Check if the cooker hood offers multiple fan speed options. Lower fan speeds generally produce less noise compared to higher speeds. Having the flexibility to adjust the fan speed allows you to balance noise levels with the required ventilation.

3. Extraction Power: Consider the extraction power of the cooker hood. Hoods with higher extraction rates are generally more efficient at removing odours and fumes, which can help reduce the need to operate the hood at high speeds, resulting in lower noise levels.

4. Noise Reduction Features: Look for cooker hoods that incorporate noise reduction features such as insulated motors, vibration dampening materials, or sound-absorbing panels. These features can help minimise noise levels during operation.

5. Installation: Proper installation is crucial for reducing noise levels. Ensure that the cooker hood is installed correctly, including secure mounting and proper alignment, as poor installation can contribute to increased noise and vibrations.

By considering these factors, you can choose a cooker hood with lower noise levels, providing a quieter and more comfortable kitchen environment.

How are cooker hood noise levels measured?

Cooker hood noise levels are measured in decibels (dB). A sound meter or anemometer is placed at a standard distance from the hood, often 1 metre, in a controlled environment. The hood is then operated at various speeds to determine the noise output. The lower the dB rating, the quieter the hood. The noise level you may measure at home can’t be compared to that in a controlled environment, usually people measure using a mobile app in an already noisy environment. So if you are checking if the specification is right you’ll need a sound chamber and some expert equipment!

How do I reduce the noise of my cooker hood?

• To reduce the noise of your cooker hood:
• Ensure that the ducting is of the right size and as straight as possible.
• Clean or replace the filters regularly.
• Opt for a cooker hood with a higher capacity than required so you can run it at a lower speed.
• Check for any loose components or parts which may cause vibrations.
• Consider investing in soundproofing materials or barriers around the hood's motor or ducting.
• Ensure that the hood is installed correctly and consult the manufacturer's guidelines for any further recommendations.
