Cooker Hood Buyer’s Guide: How to Choose the Right One

Choosing a cooker hood? It can be a daunting task. Between the marketing jargon, indecipherable spec sheets, and a jungle of designs, it's easy to make a mistake. Our mission: to help you cut through the noise and identify the criteria that truly matter for equipping your kitchen with an effective, built-to-last ventilation solution.

The 3 Pitfalls to Avoid When Buying a Kitchen Hood

Before you even start comparing models, let's review the classic mistakes that lead to disappointment and unnecessary expense.

1. The Noise Trap: Falling for Raw Power. Focusing solely on extraction power (the airflow rate in m?/h) is a common error. An overpowered but deafening hood will turn your kitchen into an airport runway. The noise level, expressed in decibels (dB), is an equally essential criterion.
2. The Ducting vs. Recirculation Confusion. Buying a ducted hood without an external vent is a classic misstep. This mode requires construction work to create an air outlet. Conversely, a ductless hood (or recirculating hood) is much simpler to install but requires regular maintenance of its charcoal filters.
3. The Design-Over-Practicality Illusion. An angled hood made of glass looks very chic, but it can quickly become a cleaning nightmare, collecting fingerprints and grease splatters. Similarly, a hood that's too small for your hob will never properly capture fumes.

The Essential Parameters for Choosing Your Cooker Hood

To make the right choice, three technical characteristics must be scrutinized. This trio will determine the efficiency, comfort, and compatibility of your future hood.

1. The Performance Duo: Airflow (m?/h) and Noise Level (dB)

A hood's performance is, above all, a matter of balance.

• Airflow (m?/h): This measures the volume of air the hood can process in one hour. For a closed kitchen, a simple calculation rule exists: multiply the room's area (in m?) by its ceiling height, then multiply the result by 10. For a 12 m? kitchen with a 2.5 m ceiling, the requirement is about 300 m?/h (12 x 2.5 x 10). For a kitchen open to the living room, increase this coefficient to 15.
• Noise Level (dB): This is the noise emitted by the hood at its maximum speed. We consider a hood is quiet when it's below 60 dB. Above 65 dB, the noise becomes genuinely disruptive, especially in an open-plan kitchen.

2. Ventilation Mode: Ducted or Recirculating?

Here, everything depends on your home's layout.

• Ducted Mode: The air is drawn in, its grease is filtered out by a metal filter, and it's then expelled outside through a duct. This is, by far, the most effective solution for eliminating fumes and humidity. It's preferred in detached houses or modern apartments already equipped with a dedicated duct.
• Recirculating Mode: The air is drawn in, passes through a grease filter and then a charcoal filter that neutralises odours, before being reinjected into the kitchen. This is the go-to solution for apartments without an external vent. Be aware: charcoal filters must be replaced every 3 to 6 months.

3. Dimensions and Installation Type

Golden rule: the hood must be at least as wide as your hob to effectively capture fumes.

• Standard Widths:60 cm hood models correspond to standard hobs. A 90 cm hood will be necessary for wider hobs or kitchen islands.
• Installation Types:
  • Wall-Mounted Hood: The classic, fixed to the wall above the hob.
  • Integrated Hood (or Canopy Hood): Ensures seamless integration. It fits into an upper cabinet and extends (for telescopic models) when in use.
  • Angled Hood: For a modern look. It frees up visual space and prevents you from bumping your head.
  • Portable Air Extractor: The innovative, portable solution. Perfect for studios, rentals, or even for a barbecue on the balcony, it requires no installation.

Frequently Asked Questions (FAQ)

1. What power (m?/h) should I choose for my cooker hood? The rule is simple: measure your kitchen's area (m?), multiply it by the ceiling height, then multiply this volume by 10 (for a closed kitchen) or 15 (for an open-plan kitchen). The result gives you the minimum required airflow in m?/h for effective air renewal.

2. When should I change the charcoal filters on a recirculating hood? For a recirculating hood, changing the charcoal filters is crucial for neutralising odours. Generally, it is recommended to replace them every 3 to 6 months. This frequency varies with your usage: frying and grilling, for example, saturate the filters much faster.

3. Is installing a cooker hood mandatory? In new constructions, regulations (such as the UK's Building Regulations Part F) mandate a general ventilation system, including the extraction of stale air from the kitchen. While a cooker hood isn't explicitly mandatory everywhere (especially in renovations), it remains the most effective solution for locally treating cooking pollutants. It is therefore highly recommended for maintaining indoor air quality.
