Extractor fans are an essential part of any home’s ventilation system, particularly in the kitchen and bathroom. They remove unwanted moisture, smoke and odours from the air ensuring a clean and healthy environment. An extractor fan is a type of mechanical ventilation device that draws out stale or polluted indoor air from a room and replaces it with fresh outdoor air. It does this by creating negative pressure that forces the air out through a duct or vent. Extractor fans are commonly used in kitchens and bathrooms where there is high humidity and strong smells.

Importance of Extractor Fan Installation in the Kitchen and Bathroom

Extractor fans play a crucial role in maintaining good indoor air quality by removing moisture, smoke, cooking smells, and other pollutants that can affect our health and well-being. In the kitchen, cooking produces steam which can quickly build up on surfaces such as walls and ceilings leading to dampness which can lead to mould growth. This not only damages your home but can also cause health problems such as allergies and respiratory issues. 

In bathrooms where there is hot shower water being used every day without proper ventilation leads to damp surfaces. The dampness also leads to mould growth on surfaces such as walls, ceiling or around window sills leading to severe respiratory issues such as asthma if not handled properly. 

Benefits of Having an Extractor Fan

Having an extractor fan installed in your kitchen or bathroom comes with numerous benefits apart from just health reasons: 

  • Reduced Humidity: extractor fans remove humidity from the bathroom and kitchen reducing the risk of condensation, mould and mildew growth which can be hazardous to health and cause respiratory issues
  • Improved Indoor Air Quality: extractor fans help remove pollutants such as smoke, cooking odours and damp air from your home leaving you with fresh and clean air to breathe.
  • Prevents Damage to Your Property: Dampness in your home can cause significant damage to walls and ceilings over time. By removing moisture from the air extractor fans help prevent this damage.
  • Saves Energy: By reducing humidity levels in your home, extractor fans can also help reduce your energy bills. This is because drier air is easier to heat or cool than humid air which often requires a lot of energy for temperature regulation.

Types of kitchen extractor fans 

Kitchens can be fitted with a standard or typical extractor fan or alternatively, range hoods or cooker hoods. These are all a type of ventilation system that removes smoke, heat and steam from the kitchen when cooking. The hoods come in various sizes and types and operate by extracting air from the kitchen and filtering it to prevent odours and grease particles from spreading throughout the home. The purpose of an extractor fan is to ensure clean air in the kitchen space while also preventing smoke alarms from going off due to excessive steam or smoke. 

There are three primary types of kitchen cooker hoods/extractor fans: wall-mounted, island and downdraft. 

Wall mounted cooker hoods are mounted against a wall above a cooker or hob 

They are among the most common type of cooker hoods due to their ease of installation and affordability. Island cooker hoods or extraction systems are installed over an island or worktop range situated in a central workstation where there is no adjacent wall for mounting purposes. 

They provide excellent extraction performance with impressive aesthetics but tend to be more costly due to their unique design features. Downdraft extractors work by sucking steam downwards through vents placed on top of the cooker or hob instead of upwards into a hood; this type is placed near/on your worktop so works well where space above is limited. 

Bathroom Extractor Fan Location

Extractor fans in the bathroom are essential for maintaining good air quality and removing moisture that can lead to mould and mildew growth, which can be detrimental to your health. Bathroom extractor fans not only eliminate odours but also prevent steam from building up on mirrors, walls, and ceilings. 

There are two ways of installing bathroom extractor fans – ceiling-mounted and wall-mounted. 

Ceiling-mounted extractor fans are installed directly into the ceiling of your bathroom, while wall mounted extractor fans are installed on an exterior wall or window. Wall-mounted fans tend to be easier to install because they don’t require any additional ductwork if installing on an exterior wall. They also tend to be more efficient as the air is expelled directly to the outside air without the need for ducting that can create resistance and reduce the efficiency of the fan. Where possible we always recommend installing a bathroom fan directly on an outside wall. 

Types of Bathroom Extractor Fans

Standard extractor fans: 

Standard extractor fans are the most basic and common type. They typically include an on/off switch and sometimes a pull cord for easy operation. A good example is the Xpelair VX100 4″Bathroom Extractor Fan, which offers reliable and efficient performance.

Timer extractor fans: 

These fans are equipped with a built-in timer that keeps the fan running for a pre-set period after you turn off the light. This ensures all moisture is extracted. The XPELAIR SILENT BATHROOM FAN WITH TIMER C4TSR is a good example, known for its quiet operation and energy efficiency.

Humidistat extractor fans: 

These fans come with a built-in humidity sensor that turns on the fan when the humidity level in the bathroom rises above a certain point. The Envirovent SIL100T Silent-100T Axial Silent Extractor Fan is a well-regarded example, popular for its silent operation and effectiveness in preventing mould and dampness.

Continuous extractor fans: 

Also known as 24/7 extractor fans, these fans run constantly at a lower speed to maintain good air quality. The Nuaire Faith Continuous Flow Extractor Fan offers continuous operation mode as well as adjustable boost

Heat recovery extractor fans: 

These units are designed to extract stale air and recover the heat before it is expelled. They then use this heat to warm the incoming fresh air. They are energy-efficient and ideal for colder climates. An example is the Vent-Axia 441625 Lo-Carbon Tempra Single Room Heat Recovery Unit, which is designed to offer heat recovery for smaller spaces like bathrooms.

Factors to Consider when Choosing an Extractor Fan

When choosing an extractor fan there are several factors you should consider in order to ensure you choose one that meets your specific needs: 

  • The room: The size of the fan you need is determined by the size of the room and extraction rate required and the type of rom. For example a larger bathroom will require a larger fan with a higher airflow rate.
  • Noise level: you’ll want a fan that is quiet enough not to disturb you but still strong enough to do its job effectively.
  • Airflow rate: The airflow rate measures how much air the fan can move per minute. This is important because it determines how quickly the fan can remove moisture and odours from your bathroom.
