Silence is golden

Good bathroom ventilation is vital to ensure the home doesn’t suffer from condensation and mould. However, modern households increasingly demand an extractor fan that not only provides good indoor air quality but also is near silent in operation.

Sound levels are an important comfort issue, with nuisance noise causing unnecessary stress in the home.

The average extract fan operates at 35 decibels. This is loud in a confined space.

Here are some steps that can help achieve a peaceful bathroom.





  1. Select a silent fan: The acoustics of bathroom extractor fans have improved recently and so electricians can now easily select the right fan for the job. For example, Vent-Axia’s Lo-Carbon Svara runs at just 17dBA, quieter than a whisper.
  2. Third Party Accreditation: The Quiet Mark is awarded by the Noise Abatement Society and is given World-Wide to manufacturers of the quietest products. Quieter products, such as the Svara, can easily be selected via the online Quiet Mark Directory
  3. Select the right size fan: Ensure the fan fits the needs of a bathroom, do not oversize a fan. The more powerful a fan potentially the noisier it will be. Also, avoid long duct runs that may result in excessive levels of air resistance which can be noisy.
  4. Motors: Select fans with high efficiency motors since the ball bearing technology used in them offers smoother and therefore quieter performance.  They will also last longer, meaning the fan won’t get noisier over time.
  5. Silent scheduling: The latest bathroom fans, such as the Svara, offer App Control with silent scheduling and automatic cycles, offering flexible ventilation to suit a household’s lifestyle.
  6. Avoiding nuisance running: Quiet, disturbance free running is the holy grail of ventilation. Good options to look out for are: clever light sensors that recognise room occupancy through light movement and shadows; a delay-on feature that can be set to avoid the fan being triggered in the night during quick bathroom visits; and fans that don’t trigger at ambient humidity changes in the night.
  7. Siting the fan: The ideal site is the shortest route to outside, preferably directly through an outside masonry wall. Where possible avoid mounting fans on plasterboard ceilings or stud partition walls since vibrations may amplify noise.


Households are increasingly aware of the benefits of health and wellbeing with IAQ and silence central to household comfort. Therefore, now is a great time for electricians to help customers switch on to the latest generation of silent extractor fans that offer the level of comfort and control demanded in the home.
