As with the model types, there is a wide variation, but generally they fit into the 60, 70 or 90cm sub-categories. In-built and integrated hoods tend to be smaller as they need to fit both the depth and width of a standard kitchen storage cupboard.
Chimney cooker hoods vary in size of the hood, the height of the chimney, and the diameter of the duct you will need. Island hoods tend to be much larger as they will likely be clearing a large area. It is worth bearing in mind the space your hood will fit into, as well as how big your kitchen is and how the size of the product effects the design.
How Cooker Hoods Work
These items play an important role in the overall function of your kitchen, so you need to think about whether they will work correctly for your needs as well as how they complement your other appliances. Extraction hoods remove the necessary air from your kitchen and send it outside via a ventilation hose.
They need to be mounted to either an external wall or somewhere where the hose can reach outside, so are very reliant on the layout of your room (but most modern kitchens will cater for this). If you can’t vent it externally, a hood that offers air recirculation is your best option. Charcoal filters remove unwanted odours and smoke, before releasing the air back into the room, making them fully flexible. Most modern-day hoods give you both options.
This number determines how quickly your hood is able to remove bad air and is given as a rate per hour. The larger your kitchen space, the larger the rate required for fast action. As a recommendation, the rate should be 12x the size of your kitchen – meaning the air can be changed 12 times in an hour to guarantee full purification.
This ranges from A+ to G, as with all electrical appliances. The higher the efficiency rating, the better for the environment and the lower the cost to run. As there is a lot for an extraction fan to do, including lighting, they generally rate quite low but plenty of high rated appliances are available.
How Often Will I Have To Clean The Cooker Hood?
To keep your kitchen grease free, you should ideally clean your grease filter once a month. This also ensures grease does not build up on the filter, which may cause a lack of fresh air and stubborn smell after time.
Some filters are dishwasher safe, but the majority aren’t, so if this is something you are conscious about you may have to spend nearer the top end of the price range. The charcoal/carbon filters will also need to be maintained and replaced every so often, so ensure you get to grips with how to do this and look into how expensive they are to replace. Before you buy, ensure this will be achievable.
Do I Need Lighting?
The majority of modern cooker hoods provide extra lighting, but the type differs greatly. LED lights are the most energy efficient and longer lasting, and halogen or bulb lights may need replacing more frequently depending on how much they are used.
Think about whether you want LED lighting that is expensive to replace but has an average life span of 15 years or you would rather spend smaller amounts more frequently. All of the cooker hoods we have featured have in-built lighting. It is good to research how expensive the lights would be to replace, and if you would be able to do it easily yourself. Most have more than one light, as well.
How Should I Fit The Cooker Hood?
The majority of manufacturers recommend that you consult a qualified engineer when fitting an item that concerns electricity supply and wiring. A lot of suppliers offer an instillation service, whether free or at an extra cost, and most will remove your old product for recycling.
How Loud Will The Extraction Fan Be?
If you are after a cooker hood which will offer little disturbance sound wise, then look for a 45dB to 66dB item. If the product is large and needs to clear a large space, be prepared for it to be a bit louder as it has to work a lot harder than its smaller counterparts.
