Extractor fans vs Ventilation Systems: which is better for your home?

As homeowners, we all want to ensure that the air we are breathing inside our homes is clean and healthy. Poor indoor air quality can lead to various respiratory problems, allergies and other health issues. This is where extractor fans and ventilation systems come into play. Both these systems are designed to improve the indoor air quality of your home by providing fresh air and removing stale, polluted air. But which one is right for your home? In this blog post, we will compare extractor fans and ventilation systems to help you make an informed decision. As a leading supplier of electrical products, Electrical Discounted Supplies has years of experience in helping homeowners choose the right ventilation system for their homes. So, sit back and read on to find out which system is the right fit for your home.

Extractor Fans

Extractor fans are mechanical ventilation systems that are typically installed in kitchens and bathrooms. These systems work by extracting the stale, humid air from inside your home and expelling it outside, thus improving the air quality inside. There are various benefits to installing extractor fans in your home, including:

  • Improved air quality: Extractor fans remove moisture, pollutants, odours and other contaminants from the air inside your home, improving the overall air quality.
  • Prevents condensation: Extractor fans can help prevent the build-up of condensation, which can lead to damp and mould growth.
  • Reduces energy costs: By removing excess moisture from the air, extractor fans can help reduce the workload on your heating and cooling systems, thus saving on energy costs.

There are different types of extractor fans available on the market, including:

  • Axial fans: These fans are simple and inexpensive and are suitable for small spaces like bathrooms.
  • Centrifugal fans: These fans are more powerful and are suitable for larger spaces like kitchens.
  • Inline fans: These fans are mounted in the ductwork and are suitable for spaces where ceiling installation is not possible.

Ventilation Systems

Ventilation systems are designed to provide a steady flow of fresh air into your home while removing stale air. These systems are more complex than extractor fans and are typically installed in larger homes or buildings. There are two types of ventilation systems available: mechanical and natural.

1. Mechanical ventilation systems

These systems use mechanical means to bring fresh air into your home and extract stale air. This can be done through one of the following methods:

  • Positive pressure ventilation: This system brings fresh air into your home through a fan or air supply unit and expels stale air through natural leakage points.
  • Heat recovery ventilation: This system uses heat exchangers to transfer heat from the stale air being extracted to the fresh air being brought in, thus reducing energy costs.

Benefits of mechanical ventilation systems include:

  • Consistent airflow: Mechanical systems provide a consistent flow of fresh air into your home, regardless of external factors like weather conditions.
  • Improved indoor air quality: By constantly bringing in fresh air and extracting stale air, mechanical systems help improve the air quality inside your home.
  • Energy efficiency: Heat recovery ventilation systems can help reduce energy costs by transferring heat from the stale air being extracted to the fresh air being brought in.

2. Natural ventilation systems

These systems rely on natural means, like wind and temperature differences, to bring fresh air into your home and extract stale air. This can be done through one of the following methods:

  • Window trickle vents: These small vents can be installed in windows to allow a small amount of fresh air to enter your home.
  • Passive stack ventilation: This system uses a vertical duct to draw in fresh air and expel stale air, relying on natural temperature differences to create airflow.

Benefits of natural ventilation systems include:

  • Low energy costs: With no mechanical components, natural systems require less energy to run and maintain.
  • Simple installation: Natural systems can be easier and less expensive to install than mechanical systems.
  • Connection to nature: Natural ventilation systems allow for a connection to the outside world, bringing in fresh air and creating a natural environment inside your home.

Factors to Consider When Choosing Between Extractor Fans and Ventilation Systems

When it comes to choosing between extractor fans and ventilation systems, there are several factors to consider. Here are some of the most important ones:

  1. Room size and location: The size and location of the room will play a big role in determining which option is best. Smaller rooms may only need a simple extractor fan, while larger rooms or open-plan areas may require a more comprehensive ventilation system.
  2. Purpose of the room: The purpose of the room will also determine the type of ventilation system needed. For example, a kitchen or bathroom may require a more powerful extractor fan to remove steam and odours, while a bedroom or living room may benefit from a heat recovery ventilation system to improve air quality.
  3. Budget: The cost of installation and ongoing maintenance is another important consideration. Extractor fans are generally less expensive to install, but may require more frequent maintenance. Ventilation systems, on the other hand, may have a higher upfront cost but can be more energy-efficient in the long run.
  4. Noise level: If noise levels are a concern, it’s important to choose a system that operates quietly. Some extractor fans can be quite loud, while heat recovery ventilation systems are generally quieter.
  5. Energy efficiency: Finally, consider the energy efficiency of the system. Heat recovery ventilation systems are generally more energy-efficient than traditional extractor fans, as they capture and reuse heat that would otherwise be lost. This can help to reduce energy costs over time.


In conclusion, both extractor fans and ventilation systems have their own advantages and disadvantages. When choosing between the two, it’s important to consider factors such as room size and location, purpose of the room, budget, noise level, and energy efficiency.
