Compared to cooker hoods, kitchen extractor fans may seem like the less necessary item in your kitchen. But don’t let their small size fool you.

In this blog, we will answer the question ‘Do kitchen extractor fans really work?’

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.

Can I get mould in my house even if I use an extractor fan?

In some instances, mould can still appear even if you use an extractor fan and have a ventilation routine, through no fault of your own.

This occurs as a result of leaks from pipes, or from clogged gutters or heavy rain in which the water has managed to penetrate a vulnerable area in your brickwork. Eventually, the moisture finds its way into your home through the walls.

When this happens, it doesn’t create mould straight away, it takes time. Usually, people don’t realise there is an issue until mould or damp appears. Unfortunately, by this time, professional repairs are required.

Either way, professionals are required in order to rectify these issues, repairs, or fixing should not be attempted by someone who is not an expert or not employed in these areas.

Using a leaking pipe for example, it may not even be coming from your home, it may just be appearing at your home. Professionals have the equipment and experience necessary to determine the source of a leak.

For example, if your home is a terraced or semi-detached house, or even a flat, your neighbours may be the reason for the leak appearing. This cannot be determined until an expert has arrived.

Do kitchen extractor fans really work?

Absolutely. Kitchen extractor fans will diligently remove any humid air it finds. Most modern extractor fans have sensors within them that allows them to understand when a room does not require any more extraction. This means you don’t have to worry about knowing when to turn it on or off.

Of course, kitchens can be large rooms in some houses or buildings, so ensuring your extractor fan is up to standard is key. If your extractor fan is not working, or not as effective as it once was, it could be down to…

  • It is old.
  • It needs maintenance.
  • There may be a build-up in the ducting that has caused blockage.

In these circumstances, a replacement or quick inspection can rectify any performance issues. That being said, using a kitchen extractor fan by itself may take a long time to remove all the humidity, unless it is an industrial grade extractor.

Can I make my kitchen extractor fan work quicker?

Yes. To get the most out of your kitchen extractor fan, and ensure that it does its job quickly, you can take the following steps.

  • Close the doors that lead away from the kitchen. By doing this, you are containing the humid air in the kitchen for it to extract.
  • Open one or more windows. Or a patio/back door if it is in the kitchen, the increased airflow not only provides another exit for humid air to take, but your kitchen is also having fresh air delivered inside it.
  • Use your cooker hood. Although this step is generally required when cooking, you can also use it from time to time to speed up the removal of humidity. If the humidity or steam has come as a result of your cooking, the cooker hood should already be on.

Can I ventilate without extractor fans?

Yes. But this process will take longer, as you don’t know when the adequate level of humidity has been removed from the room, whereas an extractor fan will simply stop when it gets to the right level.

If you want to ventilate naturally, leaving a window open would be your best option. However, this can come with issues in itself, including…

  • Heat is escaping at a higher rate than using an extractor fan with the window closed.
  • An open window can be a risk to the security of the home, especially if it is left open all night.
  • Bugs can easily enter your home with a window that is constantly open.
  • Rain can enter your home through the window, and unaddressed wet surfaces can become a breeding ground for mould.

What happens if I get mould in my kitchen?

Mould in your kitchen is one of the worst possible places it can form and thrive. This is because our kitchens are not only where we make our meals, but where we generally store food.

If mould is within the vicinity of food for a prolonged period, it is likely that the spores that mould uses to travel, can find itself on the food. This does not mean that the food will grow mouldy instantly, but it does mean that you may be consuming mould spores as well as breathing them in.

Health effects of mould

The health effects of mould can be far-reaching depending on your sensitivity towards it, in addition to any health issues you may already be experiencing, especially those with compromised immune systems or breathing issues.

Here are some signs that mould could be impacting you. It is more relevant if you didn’t have any of these issue until you had extended periods amongst mould.

  • Hair thinning/ hair loss.
  • Weaker immune system, more obvious if you go from rarely being ill to regularly being ill.
  • A lingering cough.
  • Unexpected skin rashes.
  • A lack of vitality.
  • Breathing that is slightly more laboured than usual.
  • Breathing in the outdoors is more comfortable, than breathing in the home with mould.
  • Regular or increased instances of having phlegm in your throat without any illness or contaminants that affect your lungs, such as cigarettes.

And more.

The most definitive way to understand if these issues are caused by mould, is by spending an extended period of time away from it, if those symptoms go, then you were being impacted by an allergy to mould. Additionally, seek your doctor to see if the symptoms you are experiencing are due to other health issues.

Either way, mould should be removed as soon as you notice it. It is not worth the risking of your health, regardless if it is only a tiny bit of mould. It will spread.
