How to Choose a Cooker Hood: Common UK Buying Traps to Avoid

A good cooker hood, or kitchen extractor fan, is the unsung hero of the modern kitchen. It works quietly in the background, whisking away steam, smoke and cooking odours, leaving your home fresh and clean. But choosing the right one can feel like navigating a minefield of technical jargon and marketing promises. Many homeowners end up with a model that is either too loud, too weak or simply wrong for their space.

As the Joybuy Product Recommendation Officer, my role is to help you sidestep these issues. Before you spend your hard-earned money, let’s look at the three most common pitfalls that catch UK buyers out.

1. The "More Power is Better" Myth: Many shoppers are drawn to the highest extraction rate (measured in cubic metres per hour, or m?/h), assuming it means better performance. However, this often comes at the cost of noise. A powerful fan that sounds like an aircraft taking off is one you will hesitate to use, defeating its purpose entirely.
2. Ignoring Long-Term Maintenance: The focus is often on the initial purchase price, but the type of filter a hood uses dictates ongoing effort and cost. Models with disposable carbon filters require regular replacements, while those with washable metal filters need frequent cleaning. Overlooking this can lead to frustration and reduced efficiency.
3. The "One Size Fits All" Fallacy: A cooker hood is not just an appliance; it is an integral part of your kitchen's design and workflow. Choosing a large chimney cooker hood for a small, low-ceilinged kitchen can be a disaster, just as a small built-in extractor hood will be ineffective over a large 90cm range cooker.

By understanding these key factors, you can make a much more informed decision.

Core Features to Check Before You Buy

To avoid the traps above, focus on these three non-negotiable specifications. Getting these right is the key to finding a cooker hood that serves you well for years.

1. Extraction Type: Ducted vs. Recirculating

This is the most critical decision and depends entirely on your property.

• Ducted Cooker Hood: This type vents the air directly outside through ducting in your wall or ceiling. It is the more effective method for removing moisture, grease and odours completely from the kitchen. If you can install ducting to an external wall, this is generally the preferred option.
• Recirculating Cooker Hood: If venting outside is not possible (common in flats or terraced houses), a recirculating cooker hood is your solution. It works by drawing air through a grease filter and then a charcoal (or carbon) filter, which neutralises odours before releasing the cleaned air back into the kitchen. Remember that these carbon filters need to be replaced every 3-6 months to remain effective.

Many models offer both options, giving you flexibility, but you must know which method your kitchen can accommodate before you buy.

2. The Balance: Extraction Rate (m?/h) and Noise Level (dB)

Instead of just looking for the highest extraction rate, find the right balance for your kitchen size and your tolerance for noise.

• Extraction Rate (m?/h): To find the power you need, use this simple calculation: measure your kitchen's volume in metres (Length x Width x Height) and multiply it by 10. This gives you the minimum recommended extraction rate in m?/h for clearing the air ten times per hour. For example, a 4m x 3m kitchen with a 2.5m ceiling (30m?) would benefit from a hood with an extraction rate of at least 300 m?/h.
• Noise Level (dB): This is often overlooked. A normal conversation is around 60 decibels (dB). A quiet kitchen extractor will operate at or below this level on its higher settings. Anything approaching 70 dB can be intrusive, especially in an open-plan living space. Check the dB rating for the fan's maximum speed.

3. Size and Style: Matching Your Hob and Kitchen Design

The size of your cooker hood should, at a minimum, match the width of your hob to ensure effective capture of steam and fumes.

• Standard Sizes: The most common sizes are the 60cm cooker hood for standard four-ring hobs and the 90cm cooker hood for larger hobs and range cookers.
• Styles:
  • Chimney Cooker Hood: A classic, prominent style that mounts to the wall and vents up through a chimney. Available in finishes like stainless steel cooker hood or a modern black cooker hood.
  • Telescopic Cooker Hood: A discreet, space-saving option that sits flush within a cabinet and slides out when needed. Ideal for smaller or minimalist kitchens.
  • Built-in/Canopy Hood: Designed to be fully integrated into a kitchen cabinet above the hob, making it almost invisible.

Frequently Asked Questions

How often should I clean my cooker hood filters?

For hoods with washable aluminium grease filters, it is advisable to clean them every 2 to 4 weeks, depending on how heavily you cook. Most are dishwasher-safe, which simplifies the process. If you are using a recirculating cooker hood, the internal carbon filters cannot be cleaned and must be replaced. This is typically required every 3 to 6 months.

What is the ideal height to install a cooker hood?

Safety is paramount here. While it varies by model, a general guideline is to install the hood a minimum of 65cm above an electric hob and 75cm above a gas hob. However, you must always read and follow the specific manufacturer's installation instructions for your chosen model to ensure safe and effective operation.

Are cooker hoods expensive to run?

Modern cooker hoods are generally not expensive to run. Look for the Energy Efficiency Class on the product specifications, where 'A' ratings are the most efficient. Models with LED lighting consume significantly less electricity than those with older halogen bulbs. The annual energy consumption (listed in kWh/a) can give you a good idea of running costs, but for most households, it will only add a small amount to your yearly electricity bill.
