Choosing a Cooker Hood: A Practical UK Buying Guide

A great meal can bring a household together, but the lingering smells of fried onions, fish and spices can be an unwelcome guest. A quality cooker hood is not just an appliance; it's the key to a fresh, clean kitchen. However, navigating the market can be confusing. Many shoppers are drawn in by impressive-sounding specifications, only to find their new kitchen extractor fan is either too loud, too weak or a hassle to maintain.

As the Joybuy Product Recommendation Officer, my role is to help you sidestep these common issues. Before you buy, be aware of these frequent pitfalls:

• The "Bigger is Better" Extraction Rate Myth: A high extraction rate (measured in cubic metres per hour, or m?/h) looks great on paper. However, an oversized motor in a small, well-sealed kitchen is not only inefficient but can also be incredibly noisy, turning your cooking space into an industrial zone.
• Overlooking Long-Term Filter Costs: Many adverts highlight sleek designs but gloss over filter maintenance. A recirculating cooker hood requires carbon filters that need regular replacement, adding a recurring cost. Cheaper models may use non-standard filters that are difficult to find and expensive to replace.
• Ignoring Kitchen Layout and Style: A grand chimney cooker hood might look fantastic in a showroom, but in a compact kitchen with low ceilings, it can feel overwhelming and steal valuable cabinet space. The style must match the room's practical needs.

Decoding the Core Specifications

To make a sensible choice, focus on the specifications that truly matter for performance and daily use. Here are the three non-negotiable factors to check.

1. Balancing Extraction Rate (m?/h) and Noise Level (dB)

The primary job of a kitchen extractor fan is to remove steam, grease and odours. The power to do this is its extraction rate. A simple way to estimate the power you need is to calculate your kitchen's volume (Length x Width x Height in metres) and multiply it by 10. This gives you a rough target for the m?/h rating.

• For a small kitchen (e.g., 3m x 3m x 2.4m): A rate of around 250-350 m?/h is often sufficient.
• For a larger or open-plan kitchen: You may need a rate of 500 m?/h or more.

However, power comes with a trade-off: noise. A cooker hood's noise level is measured in decibels (dB). A quiet conversation is around 60 dB. An extractor running at over 65 dB can make it difficult to talk or listen to the radio. Look for a model that provides the extraction power you need without exceeding a comfortable noise level for your household.

2. Ducted Extraction vs. Recirculation

Your kitchen's layout will determine which ventilation type is suitable.

• Ducted Extraction: This method vents air directly outside through a duct in an external wall. It is the more effective way to remove all moisture, grease and odours permanently. It requires professional installation and access to an outside wall.
• Recirculating Cooker Hood: This type is ideal for flats or kitchens on internal walls where ducting isn't possible. It works by pulling air through a grease filter and then a carbon filter, which neutralises odours before releasing the cleaned air back into the kitchen. The primary consideration here is that the carbon filters must be replaced every 3-6 months, depending on use.

3. Finding the Right Size and Type

The size and style of your cooker hood should align with your hob and kitchen design.

• Size: The hood should be at least as wide as your hob to capture steam and fumes effectively. A 60cm cooker hood is standard for most four-ring hobs, while a 90cm extractor hood or wider is needed for range cookers and larger hobs.
• Type:
  • Chimney Cooker Hood: A popular, visible style mounted on the wall, with a flue extending to the ceiling. Available in materials like stainless steel and black glass.
  • Integrated Cooker Hood: Designed to be hidden inside a kitchen cabinet for a seamless, minimalist look. Also known as an under cabinet hood.
  • Angled Cooker Hood: A modern, slanted design that provides more headroom over the hob, making it a great choice for taller individuals or for creating a sense of space.
  • Telescopic Extractor Hood: A space-saving variant of an integrated hood that slides out from under a cabinet when in use and retracts when finished.

Frequently Asked Questions

Q1: How often should I clean my cooker hood filters?

For optimal performance, the metal grease filters should be cleaned regularly. For most households, this means once a month. Many are dishwasher-safe, which simplifies the process. If you have a recirculating cooker hood, the internal carbon filters cannot be washed and must be replaced. This is typically required every 3 to 6 months or when you notice odours are no longer being effectively removed.

Q2: Can I install a cooker hood myself?

For a simple like-for-like replacement of a recirculating hood, a competent DIYer may be able to perform the installation. However, for any new installation, especially one involving ducted extraction or electrical wiring, it is strongly recommended to hire a qualified professional. This ensures the appliance is fitted safely, securely and in compliance with all UK building and electrical regulations.

Q3: What is the main difference between a ducted and a recirculating cooker hood?

The key difference is where the air goes. A ducted hood vents the air completely out of your home through a pipe in the wall. This is generally more effective at removing moisture and all airborne particles. A recirculating hood filters the air through grease and carbon filters and then releases it back into the kitchen. It is easier to install but relies on the filters to clean the air, which requires ongoing maintenance.
