Is It Worth Having an Extractor Fan in a Kitchen?

For those who are beginning to understand the complexities presented by some kitchens, or even looking towards renovating their kitchen, knowing what is required in a kitchen is important. Extractor fans are no exception.

In this blog, we will address the question ‘Is it worth having an extractor fan in a kitchen?’

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 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.

The basics of an extractor fan

An extractor fan is a ventilation device that is used to remove humidity, smells and stale air from the room it is placed in. This is done to maintain a comfortable environment, as well as mitigate condensation that is caused by humidity, which if it is left unattended, can become mould.

Is a cooker hood the same as an extractor fan?

Not exactly, a cooker hood is a type of extractor fan, its main difference is its size and level of extraction, it is much larger, and its level of extraction are naturally superior to a regular extractor fan. Understandably, this comes at the expense of extra noise, and more power usage.

Is an extractor fan the same as MVHR?

No. MVHR stands for ‘mechanical ventilation with heat recovery’. This is a form of an extractor fan, some would say, the next step in its development. MVHR units do indeed extract humid air, this is where most extractor fans finish their jobs.

MVHR units not only extract humid air, but it replaces it with filtered outdoor air, without any loss in temperature. Available in single or multi room units, it is a worthwhile investment. Especially if you have a kitchen that is usually cold, or you’re looking for the best ventilation solutions possible.

Is condensation the only cause of mould in a kitchen?

Is condensation the only cause of mould in a kitchen?

No. Mould can occur in kitchens as a result of leaks, and not cleaning wet surfaces.

Common kinds of leaks within a kitchen are as follows…

  • Piping that holds the flow of water for taps can leak over time. If this is not noticed and addressed immediately, the leak will be consistent, in addition to the fact the area under a sink is dark and usually warm, it is the perfect place for mould to develop.
  • Appliances such as your fridge or washing machine have leaked, sometimes these leaks occur in areas we aren’t able to see, such as underneath or behind the appliance. Sometimes we only notice the leak once it has spread, or we move the appliance, though this may be too late as mould has developed by this time.
  • Any walls that have pipes behind it have the chance to create mould if the pipes burst. Even if they crack by a tiny margin, any consistent flow of water, even if it is drops, can eventually become the perfect environment for mould to develop.

Can mould only occur in kitchens?

No. Mould has the potential to appear in any room in any building, house or workspace. Mould is far more likely to appear in kitchens and bathrooms simply because of the amount of water that is spilled, steam that is created, and surfaces that can be left wet. Though, improper window installation can also greatly contribute to mould development.

Is it worth having an extractor fan in a kitchen?

Is it worth having an extractor fan in a kitchen?

Absolutely, an extractor fan, whether you opt for the larger cooker hood, the smaller extractor fan, or both, is not only worth having in your kitchen, but a necessity. We believe it is necessary simply because of how easily mould can develop in a kitchen.

Extractor fans quickly cut down the time needed to remove humidity from a room, as well as leave you feeling a lot more comfortable than you would be if you always had to open windows to extract air.

That being said, opening a window whilst using an extractor fan only boosts its effectiveness, meaning the humidity, smells, smoke, or steam in your kitchen, will be gone much quicker.

What happens if I don’t have an extractor fan in my kitchen?

  • Smells can linger for a longer amount of time.
  • You are likely to develop mould in your kitchen.
  • Steam and smoke are harder to remove from your kitchen.
  • If you have no ventilation at all, you could be breaking the law.
  • You may be inflicting future repair costs on yourself by neglecting the processes required to prevent mould.

Which is the best kind of extractor fan for my kitchen?

A cooker hood is suitable for someone who cooks often, although they are large and powerful, depending on the model you have, it can run up your electricity bill.

A kitchen extractor fan is smaller, meaning it will take longer to extract the same amount as the cooker hood, but some extractor fans have automatic settings, meaning you don’t have to guess when to put it on.

If you really want the maximum benefits provided by kitchen ventilation, opting for both a cooker hood and a kitchen extractor fan is the most appropriate option.

Does an extractor fan kill mould in the kitchen?

No. We must clarify that ventilation prevents mould, it does not destroy it.

If you want to get rid of mould permanently, you should use a mould surface cleaner, followed by an anti-mould paint. Anti-mould paint has fungicidal properties that prevent mould from growing on that surface for years.

It has the potential to remove the mould permanently, but that is only possible if the cause of the mould is addressed.

Mould and its dangers

Mould will affect your health, especially if you have underlying health conditions, a mould allergy, or a weak immune system. There are many ways mould can impact your health. Common symptoms include

  • A rash.
  • A cough/sneezing.
  • Red, sometimes swollen skin.
  • Watery eyes.
  • A runny nose.
  • A sore throat.

Less common symptoms can include…

  • Hair loss.
  • Frequent bouts of illness.
  • Breathing issues/ increase in asthma issues if you already had asthma.
  • Bowel issues.
  • Stomach aches.
  •  Nausea
  •  Vomiting

Understandably, these symptoms can coincide with a multitude of other health issues. If you have visited a doctor frequently for these symptoms with no resolution, but you also have mould in your home, it could be worth removing the mould.
