How to choose a cooker hood

Regardless of the type of the cooker hood you have chosen to buy, they are all designed for purification of the air in the room. It is achieved through two methods: either by air filtration or by extract ventilation. In the first case the air is purified due to special filters built into the hood; in the second one impure air is eliminated beyond the house.

Why purify the air in the kitchen ↑

Kitchen is the working place for the homemaker. She spends there about 60% of the time in the house, so the air condition in this room directly affects her health. Kitchen air during the process of cooking is being polluted with the combustion products, the smallest particles of food produced at heating. If the room is not ventilated well enough the smells create discomfort, negatively affect the mood and may even ruin the appetite of a very hungry person. Airing is one of the method of fighting impure air. But it is better to trap polluted air right over the cooking hob and remove it from the room. That is the task for cooker hoods.

 What model is good for the kitchen ↑


One of the essential things when buying the cooker hood is its capacity. This parameter is defined by the volume of air flown through the appliance over the unit of time. Efficiency of the appliance’s work depends on it. According to sanitary regulations, overall amount of air should change in an hour. You may calculate necessary capacity for your own kitchen according to the following formula: kitchen area multiply on ceiling height, obtained result multiply on 12 (air renewal norm adopted by Health Inspection Services), and then multiply the result on the potential supply coefficient (equals to 1,3). Thus, if kitchen celling’s height is 2,5 metres and area is 6 sq. metres you will need a Cooker hood with extraction rate at 234 m3/h.


How to choose a Cooker hood right ↑

While choosing the cooker hood you should pay attention to such parameters as a type of appliance, its size, capacity, methods of appliance’s control, its operating modes and presence or absence of filters.


Width of the cooker hood cannot be less than a cooking surface. At the lesser size the cooker hood extracts polluted air worse. Even better if the cooker hood’s width exceeds the cooking surface. Thus, if your range is of 50-60 cm it is better to buy the cooker hood of about 90 cm wide, if your furniture allows it, of course.

operating mode

Inquire from shop assistant what operating modes are available in the cooker hood you have chosen. There are three options for effective air filtration: extraction with an external motor letting the air out of the house, recirculation and both of these options. Extraction mode is considered 100% efficient for air purification. However, if you decided to buy extractor-filter, you had better simultaneously buy cartridges and change them when necessary.



There can be filters of primary and fine purification. Filters of primary purification stop grease particles. They look like multiple-use synthetic meshes, which can be washed as they accumulate dirt. An additional filter is a single-use synthetic mesh, which needs to be replaced when it gets dirty because a mesh with exhausted life-span negatively affects work of the cooker hood. Filters of fine purification are the carbon filters, which are bought separately. Frequency of their replacement depends on how often the cooker hood works in recirculation mode.

control mode


Which control mode is better to choose? This depends on your personal preferences only. Cooker hoods with sensor control are activated by pressing of inset button. Button control presupposes pressing of push buttons. There can also be slider control, which is done by mechanic horizontal switch.

additional options

While making a decision of what cooker hood to buy, pay attention to additional options of the appliance: remnant ventilation, interval switch on of the cooker hood. Remnant ventilation provides operation of the cooker hood during several minutes after switching off (from 5 to 15 minutes), which allows complete air purification after the cooking is done. Interval switch on of the appliance provides switching on for a short period (for instance, once in an hour or two for 5-10 minutes) on minimum capacity. It is design for continuous flow of fresh air in the room.

Some cooker hoods have an electronic timer built in them. It is to be switched on at the end of cooking process so that the appliance can automatically switch off in a pre-set time.

Most cooker hoods come with lights to illuminate your cooking. There can be used light bulbs, halogen lamps or fluorescent lamps. Of course, cooker hoods with lightbulbs are cheaper but appliances with halogen lamps consume less electric power. You will have no troubles in replacing a burnt-out lamp.

What the efficiency of the Cooker hood depends on ↑

Efficiency of the appliance operation depends on many factors:

  • On air pressure created by the motor. If indications of air pressure are high, it means the capacity will be high.
  • On operating mode of the cooker hood. If it is connected to the ventilation duct, its operation will be more efficient than in recirculation mode.
  • Important part is played by section of grease extracting filters and density of carbon filters (if any). The higher is the density of the filter, the more efficient is odour elimination. However, you should remember that no carbon filter provides 100% air purification.
  • On excess capacity. The most efficient mode allows air purification in extreme conditions, for instance when food starts burning. When choosing the cooker hood pay attention to this parameter.
  • On the cooker hood size. The bigger it is, the bigger area it covers while catching the air. It means there will be no big turbulence of air and sides of wall-mount cabinets will not be damaged by hot air rising from the hob.


Types of Cooker hoods ↑

  • Traditional or classic cooker hoods


It is a wall-mount cooker hood, which is mounted under the kitchen cabinet over the hob. Many manufacturers offer cooker hoods with grease extraction acryl filters (for single use). Such appliances mainly work in air recirculation mode. You will need single-use carbon filters catching the small particles. Odours are expelled only partially. Such cooker hoods are the cheapest choice.

Cooker hoods, which apart from carbon filters allow connecting flexible vent duct, cost more but they purify air much better. You will also have no need to spend money on frequent replacement of carbon filters.

  • Built-in cooker hoods


They are mounted inside a wall cabinet over the hob. Usually built-in cooker hoods are furnished with a sliding panel, which expands working surface for inlet vent. This simplifies appliance control and raises its capacity. Such a cooker hood switches on in the same operating mode as it was switched off with. Built in cooker hood is usually equipped with two motors and multilayer grease filters. Built-in cooker hoods are just a bit more expensive than traditional ones, so if you cannot set your mind on whether to buy a traditional cooker hood or a built-in one, buy the latter.

  • Chimney (canopy) cooker hoods


They are wall-mount at the ceiling over the range or hob. They are called chimney hoods for their dome-shaped form reminding a fireplace chimney. Such cooker hoods may be of three types: metal and glass, fullmetal, traditional a la wood or decorated with natural wood. These chimney cooker hoods are various in design and their shape can be very creative like, for example, chimney cooker hoods in Hi-Tech style.

Functional peculiarities of choice ↑


Modern cooker hoods are capable of expelling up to 96% of odours and air impurity remaining after cooking meals. Cooker hoods are especially necessary in dining kitchens and kitchens combined with dwelling room. In cases as these, it is important that cooker hood be not just of high capacity but also have a low noise level.

Operation of the appliance may be assessed as ‘very quiet’ is the noise produced by the motor and airflow is compared to whisper (up to 35dB). If the noise may be compared to the talk on 10 m distance (up to 45 dB) you can call such work as quiet. If your kitchen is not isolated (not combined with either room or dining room), you may find no inconvenience in noise level equalling to 50 dB (quiet talk in 3 m distance). Such a noise level is evaluated as ‘normal’. We do not recommend to buy cooker hoods with noise level exceeding 50 dB. For example, it is hard to ignore 70dB noise as it can be compared to a loud conversation at about 5 metres distance.

When choosing cooker hood, also pay attention to casing material. Manufacturing materials are enamel steel, stainless steel, tempered glass, aluminium. In quality-price ratio processed aluminium looks the most appealing. Its matt surface excellently combines with many kinds of kitchen equipment. Aluminium surface of the cooker hood remains no visible traces of fingerprints, is not apt for corrosion and is easily washable. Stainless steel casing in combination with tempered glass looks very stylish. There are also very expensive models customized according to the client’s demands.
