Why You Need a Kitchen Extractor Fan
A kitchen extractor fan is no longer a luxury, but a necessity for a healthy and comfortable cooking environment. Beyond simply removing unpleasant cooking odours, these essential appliances tackle grease, moisture, and airborne particles. Consistent use improves indoor air quality, reducing the risk of respiratory issues and allergies. Without adequate ventilation, moisture can lead to mould growth, damaging kitchen surfaces like cabinets and paintwork, and also impacting the longevity of your appliances. A good extractor fan protects your kitchen and your health.
Types of Kitchen Extractor Fans
Choosing the right extractor fan depends on your kitchen layout, cooking style, and aesthetic preferences. Here’s a breakdown of the main types:
Chimney/Canopy Extractors
The most common type, these fans are mounted above the hob and feature a canopy that captures rising steam and fumes. They are generally very effective and come in a wide range of styles, from traditional to contemporary.
- Pros: High extraction rates, readily available, variety of styles.
- Cons: Can be visually dominant, require sufficient space above the hob, often require ducting to the outside.
Downdraft Extractors
These fans are integrated into the worktop behind the hob and extract fumes downwards. Ideal for kitchens where wall space is limited or you prefer a sleek, minimalist look.
- Pros: Space-saving, stylish, good for island installations.
- Cons: Generally lower extraction rates than chimney hoods, can be more expensive, installation can be complex.
Ceiling Extractors
Mounted flush with the ceiling, these fans are a discreet option for kitchens where other types aren’t suitable. They are often used in conjunction with a hob on an island unit.
- Pros: Discreet, ideal for island hobs, don’t obstruct views.
- Cons: Can be less effective than chimney hoods, require sufficient ceiling height, installation can be challenging.
Integrated Extractors
Often built into cooker hoods or cupboards, these are a space-saving solution, typically used in smaller kitchens or for a streamlined aesthetic. Often part of a whole-house ventilation system.
- Pros: Space-saving, integrated design, can be part of a MVHR system.
- Cons: Often lower extraction rates, can be more difficult to access for cleaning.

Extractor Fan Airflow & Capacity (m³/h)
Airflow rate, measured in cubic metres per hour (m³/h), indicates how much air the fan can extract. To calculate the required capacity, you need to determine your kitchen’s volume: Length x Width x Height = Volume (m³). As a general rule, you need an extractor fan that can change the air in your kitchen 10-15 times per hour. Therefore, Volume x 10-15 = Required Airflow (m³/h). For gas hobs, aim for the higher end of the range. For induction hobs, the lower end may suffice. Consider your cooking habits – frequent frying and intense cooking require a higher capacity.
Recirculating vs. Ducting – Which is Right for You?
Ducting systems vent extracted air directly outside through a duct. They are more effective at removing odours and moisture. However, they require access to an external wall and professional installation. Recirculating systems filter the air using a carbon filter and return it to the kitchen. They are easier to install but less efficient. Carbon filters need replacing every 3-6 months, adding to the ongoing cost. In 2026, improved carbon filter technology provides slightly longer-lasting filters and better odour absorption.
Noise Levels: Decibels (dB) Explained
Extractor fan noise is measured in decibels (dB). A lower dB rating indicates a quieter fan. Consider an extractor fan with a noise level below 65dB, especially for open-plan kitchens. Modern fans in 2026 often feature advanced motor technology and acoustic insulation to minimize noise. Many also offer multiple fan speeds allowing you to balance extraction power with noise levels.
Extractor Fan Features to Consider
- Lighting: LED lighting is energy-efficient and provides brighter illumination than traditional halogen bulbs.
- Fan Speeds: Multiple fan speeds offer flexibility to adjust extraction power and noise levels.
- Grease Filters: Metal grease filters are more durable and easier to clean than synthetic filters.
- Automatic Sensors: Some fans feature sensors that automatically adjust fan speed based on cooking fumes.
- Smart Home Integration: Wi-Fi-enabled fans allow remote control and monitoring via a smartphone app.
Kitchen Extractor Fan Installation: DIY vs. Professional
Installing an extractor fan can be a DIY project for experienced homeowners comfortable with electrical work. However, it’s crucial to adhere to current building regulations (Part P of the Building Regulations in England and Wales) which require electrical work to be certified by a qualified electrician. Ducting installation can also be complex, especially if it involves cutting through walls. Incorrect installation can be dangerous and void any warranties. If you’re unsure, it’s best to hire a qualified electrician or installer. In 2026, many local authorities offer online resources and guides to assist with building regulation compliance.
Maintenance & Cleaning
Regular cleaning is essential for maintaining the performance and lifespan of your extractor fan.
- Turn off the power supply before cleaning.
- Remove and wash grease filters in hot, soapy water every 2-4 weeks.
- Wipe down the fan blades and housing with a damp cloth and mild detergent monthly.
- Replace carbon filters (for recirculating systems) every 3-6 months.

FAQ
Q: How often should I clean my extractor fan?
Grease filters should be cleaned every 2-4 weeks. The fan housing and blades should be wiped down monthly. Carbon filters (if applicable) should be replaced every 3-6 months.
Q: Can I install an extractor fan myself?
You can if you’re experienced with electrical work and understand building regulations. However, it’s strongly recommended to hire a qualified electrician to ensure safe and compliant installation.
Q: What size extractor fan do I need?
Calculate your kitchen’s volume (Length x Width x Height) and multiply by 10-15 to determine the required airflow rate (m³/h).
Q: Is ducting essential?
No, but it’s more effective. Recirculating systems are an alternative if ducting isn’t possible, but they require regular filter replacement.
Q: What are MVHR fans?
Mechanical Ventilation with Heat Recovery (MVHR) fans are integrated systems that extract stale air while recovering heat to pre-warm incoming fresh air, enhancing energy efficiency.
