Excessive and constant noise can be irritating beyond measure, it has the power to stop you from relaxing, and can literally becoming quite the headache. Whether the sound is loud, or small enough to still be heard, it can be an issue.

If you have a home that requires frequent or consistent use of an inline extractor fan, will you suffer fom the effects of being bombarded with a constistent sound? Or are inline extractor fans lower on the decibel scale?

In this blog, we will provide answers to the question ‘Are inline extractor fans noisy?’

With new buildings being made to be as energy efficient as possible, and the UK aiming for 95% of its electricity usage to be low carbon by 2030, it is imperative to understand how we can make the most of our ventilation. This is where applications such as extractor fans and heat recovery ventilation units come in.

To prevent mould, fresh air should constantly be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or MVHR units. Almost all of this is facilitated by ducting.

Inline extractor fans explained

Inline extractor fans are a variation on the typical extractor fan, as opposed to being installed against a wall or window, inline extractor fans are installed within a duct. And surprisingly in some cases, they can be more effective than a standard extractor fan.

Like their traditional variant, they can be installed in bathrooms, kitchens, utility rooms, and in public buildings or establishments such as restaurants or gyms!

Can anyone install an inline extractor fan?

Yes, for the most part. Installing an inline extractor fan in the UK yourself is possible if you’re comfortable with DIY electrical work and some basic building modifications. However, there are important safety considerations and regulations to be aware of:

  • In the UK, any work involving fixed electrical wiring, including connecting the fan to the mains power supply, must be undertaken by a qualified electrician. Tampering with electrical wiring yourself can be dangerous and could lead to serious injury or fire.
  • Depending on the complexity of the installation, building regulations approval might be required. For instance, if the installation involves cutting into external walls or creating new vents, building regulation approval might be necessary. It’s always best to check with your local building authority to determine if your specific installation requires approval.

Is it easier to install an inline extractor fan or regular extractor fan?

Regardless of the approach you take, both would generally require the installation of ducting, and a qualified electrician in order to correctly wire the appliance to the electrics. In terms of the part of the installation that anyone can do, it would be safe to say a regular extractor fan would be easier to install than an inline extractor fan.

Are inline fans noisy?

Compared to a regular extractor fan, an inline extractor fan is not noisy at all. Though this is not to be confused with completely silent. An inline extractor fan will make noise, although at most it can be heard as a faint hum, this is due to the design of the machine, in addition to the fan being installed within the ducting itself.

The noise of an inline extractor can be affected by a variety of issues, the following issues will result in an inline extractor fan sounding louder than it should, including…

  • Obstructions and debris in the ducting/ fan.
  • Accumulated dust within the extractor fan.
  • The ducting being broken or unsecured.
  • Mechanical faults in the extractor fan.
  • If the fan has adjustable settings, increasing the fan speed may make it louder.
  • The fan may be too old.
  • Not using rigid ducting. Rigid ducting reduces sound output compared to flexible ducting, as vibrations struggle to travel through rigid ducting effectively.
  • Improper installation.

How can you make an inline extractor fan quieter?

In some cases, the inline extractor fan may be completely perfect in terms of installation, the fan itself, the ducting etc, even if it’s at its lowest setting. This may still be too loud for some people. In those kinds of instances, you may have to consider investing in a model with a quieter sound output.

If you haven’t tried any methods in reducing the sound output of an inline extractor fan, try these before committing to buying a new model.

  • Lower the fan speed setting.
  • Check the ducting and fan for any obstructions, damages and severe dust buildup.
  • Seek advice from a different professional to see if the installation conducted was correct.
  • Invest in stick-on soundproofing boards, these help to reduce the sound out from a certain area. They can be stuck on the wall the extractor fan noise emits from.

Is a loud inline extractor fan even an issue?

For some people, yes. Excessive noise can be different for each of us individually, as we all have our own levels of sensitivity when it comes to sound. Some people may struggle to focus or relax with excessive repetitive sound in their vicinity.

This is especially true for professionals who work from home, who require silence to do their work, especially when it comes to recording audio or video.

Additionally, repetitive distracting sound can have severe effects on your stress levels and your ability to sleep.

How to stop mould

How to stop mould

Mould usually occurs as a result of excess humidity becoming condensation that is left unattended, over time this becomes the perfect environment for mould to grow and thrive. Mould can spread quickly, harbouring a horrible smell, and affect your health.

Let’s break down these processes further, to help you understand what you can do today.

1.   Removing the mould with products

Mould can be removed with products such as a mould surface cleanser. If this is followed by applying an anti-mould paint/emulsion, you are also penetrating the mould deeper and forming a layer over which it will not be able to grow permanently, if the issue that caused it has been resolved.

2.   Fixing the issue that has caused the mould

There are a few issues that can cause the growth and continual return of mould. A common issue includes water leaks that can occur from damaged pipes.

In some instances, it may be better to use the services of a mould removal expert. These experts can accurately diagnose the source of the mould in your home and can suggest ways to remove it, or offer their services.

3.   Preventing its growth through employing routine methods

Homes without a susceptibility to mould can still fall victim to mould if there is no mould preventing routines practised.

Mould preventing routines include a ventilation routine, this involves opening the windows of your house to allow a consistent flow of air to travel through the house, replacing the humid air with fresher, outdoor air.
