First decide whether you want a cooker hood inside a wall unit or a design hood. The hood is a distinguishing element of any kitchen, particularly a classic one.
Base you choice on both design and functionality.
If the kitchen is small, you need space, so we recommend a cooker hood inside a wall unit, which will leave space for extra shelves and add uniformity to the kitchen.
The visual impact of a design hood will be greater, but you might have to give up some space. An attractive design hood will enhance even the simplest kitchen.
Technical characteristics and functions
New regulations that came into force in January 2015 require all cooker hood manufacturers to provide an energy label, which may also be consulted on the various manufacturers' websites. It provides information on the energy class (A-G), annual consumption (kW/year), noise levels, suction efficiency of the filters and the lights
3 things you should know about choosing the right cooker hood:
- a powerful motor is quieter and consumes less energy, because it works efficiently at low speeds. Efficient suction performance without exceeding 55 db(A) in sound power is quiet enough to avoid disturbing you.
- You can choose between a suction hood or a filter hood. A suction hood expels the suctioned fumes and vapours outside the kitchen and is the most efficient solution. A filter hood, also called a chemical hood, sucks the air, filters out the fumes and vapours then returns it into the kitchen. Choose long-lasting active carbon filters if you opt for a filter hood. They can be reused a number of times, simply by washing them in the dishwasher and drying them in the oven. This means they can last up to 3 years, whereas normal anti-odour filters have to be replaced every 3 months. There are also cooker hoods that ionise the air to remove over 70% of odours. They also inactivate viruses, bacteria, allergens, moulds, fungi, spores and pollen and neutralise cigarette smoke. The ionisation process imitates the natural process occurring with waterfalls, waves, lightning or high-mountain areas: it makes the air clean and healthy, through a bipolar electrical field applied to the air flow produced by the cooker hood. This cooker hood not only eliminates odours while you cook, but can also be switched on to purify the air and make it healthier.
- How do you know if a cooker hood is efficient? Work it out! Calculate the necessary suction capacity before choosing the cooker hood. There is a simple formula for calculating the necessary suction capacity according to the size of your kitchen. An efficient cooker hood exchanges the air in the kitchen 10 times per hour, so the formula is: Efficiency = m² of the kitchen x height of the kitchen x 10 air exchanges = [m3/h]. Example: a 15 m² kitchen, 3 metres in height, needs a cooker hood that suctions at least 450 m3/h. In fact: 15 x 3 x 10 = 450 m3/h. At this point, check that your chosen cooker hood has a suction capacity equal to or higher than the one calculated.
Tip: always remember to switch on the cooker hood when you cook, or rather switch it on one minute before you start. This will create an air flow that channels fumes and vapours towards the suction surfaces. And your kitchen will last longer!
