Induction hob with integrated extractor fan

Types of extractor fans

Traditionally the most common extractor fan is the wall mounted hood that sits proudly above the hob. Its purpose is to remove grease, fumes, smoke and steam from the air. While this style of extraction is still largely popular, there are now a number of options you can choose from taking into account the type of extraction method you’ll need, the design and size of your kitchen, as well as your budget. We take a look at the types of extraction methods you should be aware as well as the different types of extractor fans available to create a clean and enjoyable cooking environment.

Types of extraction methods

Extraction and recirculation are the two types of ventilation available for extractor fans, with most modern appliances offering both options. Both choices have advantages and disadvantages, so it’s important to consider which is suitable for your budget and the layout of your home before making a decision.

Extraction – Perhaps the most efficient method in terms of cleanliness and hygiene is extraction. Air is permanently removed from the room through a grease filter and ducting expelling it outside the building. While it might be the most effective method, it isn’t possible to utilise in every property for several different reasons – your kitchen might be set inside the building further than six metres from an external wall, for example.

Recirculation – Rather than removing the air entirely, recirculation passes it through a series of grease and carbon filters to remove any airborne fragrances before the air is reintroduced into the room. While this method is considered to be slightly less efficient than extraction, it does ensure warm air isn’t being expelled from the room, which is particularly useful during the winter. These systems are also less complex and expensive, but additional costs may come when the carbon filters need to be replaced in order to maintain maximum efficiency.

Types of extractor fans

Wall mounted hood
The ever so popular wall mounted hood extractor is a firm favourite in kitchen design. Today, this popular extractor has had a make-over with more options to choose from, as well as looking more aesthetically appealing. There are different sizes and finishes available including stainless steel and a sleek black as well as different shaped hoods including a flat or angled hood – this option is ideal for smaller kitchens as it is less obtrusive. If you prefer to have a ducted extractor (where the air is removed from the building entirely) then the wall mounted hood is the best choice.

Island ceiling extractor
Many of our customers request a kitchen island as a must-have for their new kitchen along with a hob located on the island as the main cooking area. This means the extractor fan needs to be located close by. A ceiling extractor built into a bulkhead (a boxy structure built onto a ceiling) directly above the hob is ideal for saving on worktop space and is out of view when cooking. Furthermore, you could also get the bulkhead to be designed to mimic the shape of your island for a design statement in the room.

Downdraft extractor
For contemporary, minimalist kitchens, a downdraft extractor is a great choice as it sits flush with your worktop when not in use. The slimline design rises out of the worktop behind the hob or to the side. The latest versions include the below by Siemens (pictured left) which is now even slimmer  with an elegant glass design that not only catches steam but the attention of your guests when lit, as it comes complete with dimmable LED lights. Bora’s Professional 3.0 option includes the downdraft system combined in-between the hob and a Tepan grill (pictured right) providing a minimal, premium option which boasts low-noise while cooking.

Induction hob with integrated extractor fan
The most space saving, minimal extractor is the extractor fan that is integrated into an induction hob. This two-in-one option sees the extractor in the middle of the hob drawing down any vapours and odours while cooking. This clever design takes away any worries about where to put an extractor fan, freeing up space in your kitchen, including space underneath for drawers.

Canopy (built-in) extractor
A canopy extractor is built into the cabinets so appears hidden in your kitchen, making them perfect for a seamless finish. This discreet option is positioned into the cabinet directly above the hob or a chimney breast offering multiple speed settings and LED lights perfect for when cooking.

Other considerations
As well as the style and extraction method, there are other considerations to be aware of. These include the noise level of your preferred extractor fan. Measured in dB (decibels) you’ll ideally want a rating of between 40-65dB for a more peaceful cooking experience.  The size of your room will also impact your purchasing decision as you’ll need an extractor fan that is strong enough to purify the air in the whole room – not just by the hob. To find out the extraction rate you’ll require, work out your room volume (length x width x height), then multiply by 10.  Whatever option you decide make sure you think about the practicality as well as the design.  Your kitchen designer can also help you to ensure you get the right type of extractor fan for your new kitchen.
