What Is the Best Bathroom Extractor Fan in the UK?

As the UK’s leading ducting and ventilation supplier, our team at I-Sells understand the critical role that extractor fans play in ensuring your bathrooms are well-ventilated. Ventilation is of paramount importance in rooms where there will be an excess of steam or odours, such as your bathroom. Improper ventilation will lead to dampness and mould, which can have serious health implications for anyone of any age.

You may be wondering what the best bathroom extractor fan is in the UK? And how can I protect my bathroom from mould or dampness? Well look no further, we have all the answers you need.

Understanding what can happen without an extractor fan


Earlier we briefly highlighted the implications of improper, or no ventilation, in your bathroom; but it is important to us that you know what the consequences can be if you aren’t using a bathroom extractor fan.


Without going into detail, it is obvious that your bathroom will be subject to various odours, people combat this by fighting it with another smell, this could be room spray, deodorant or a scented candle. These may help, but realistically you are mixing one odour with another, you must ventilate the room in order to allow fresh air to enter and to let odours outside.


Our bathrooms are where we have our showers and baths, as most of us regularly enjoy a hot bath or hot shower you will notice the steam creating condensation on windows, tiling and walls too. If you aren’t using an extractor fan or at least opening a window to allow the steam to escape, the condensation you leave in the room creates an ideal environment for mould to flourish, which can create a whole host of problems.


Mould, otherwise known as damp, is a fungus that grows on wet surfaces. Mould comes in a variety of colours: Black, Green, Brown, Grey and White. It can be difficult to identify mould by colour as it can occur in many shades. Some of the most common mould strains in the home are:

Black Mould

Also called Stachybotrys chartarum, Black mould is commonly found in bathrooms and wet rooms but can also occur on cold exterior walls in habitable rooms such as the bedroom or living room.


Commonly found in bathrooms, under sinks, and around faucets but it can grow on surfaces like carpets, furniture, walls, and floors.

Mould reproduces from tiny spores. The spores float through the air and deposit on the surfaces. Under adequate temperature, moisture, and nutrient conditions, the spores can form new mould colonies. Damp can severely affect your immune and respiratory system, as the spores are easily breathable and not obvious to see through the human eye.

If you have found dampness in your home, you need to assess if this is your landlord’s responsibility (for example it could be from a leaking roof that needs repairing). Or if the dampness is caused by improper ventilation. To assess your options, click here. If you’re a tenant and not sure about your rights when it comes to mould in a home you are renting, check out our blog for the answers you need.

At I-Sells, aside from superior ventilation for your bathroom, we also sell mould-control paints and cleaners which will remove and/or prevent mould from growing in your home as long as adequate care is taken.

How to keep your home free from condensation

Although the introduction of the best bathroom extractor fan that we offer would significantly improve the airflow of your bathroom, we also have a few tips you can do to ensure your bathroom is safe from the dangers of mould. You should try:

  • Open the window during and after a hot shower/bath – This allows the steam to escape and be replaced with fresh air and also lowers the degree of condensation that will appear, especially on colder days/evenings.
  • Reducing bathing time – Doing this means that your bathroom will be subject to less steam and therefore less condensation.
  • Create airflow in your home – Open a window downstairs and another upstairs, allowing the rising warm air to leave upstairs whilst letting the cooler fresh air enter the home. In colder times of the year, doing this for a minimum of 20 minutes can help. In flats, opening multiple windows can have the same effect.
  • Remove bathroom carpets – carpets in a bathroom will retain the moisture within its fabrics, eventually evaporating and causing more unwanted moisture in your bathroom.
