How to choose a reliable kitchen hood: tips for pros
The question of how to choose a kitchen hood, interests all those who started repairing the house. With particular care to the choice of this technique are the mistresses, who have already seen how, in fact, bad without this tool.
Regardless of what you decide to buy the device, all designed to clean the kitchen. This is done in two ways: by air filtration or exhaust ventilation. In the first case, the air is cleaned, thanks to special filters that are built in the hood, in the second - the polluted air is removed from the premises.
Why clean the air in the kitchen
The hostess spends 60% of her time in the kitchen, her health depends on the state of the kitchen environment. The microclimate during cooking is contaminated with combustion products, the smallest pieces of food that are released when heated. If the room is not well ventilated, odors create discomfort. They negatively affect the mood of people, they can repel the appetite even from the hungry. Airing is one of the ways to deal with polluted air. But it is best to catch gassed air directly above the stove and to release the room from it. With this task, kitchen extractors can cope.
What model to buy for the kitchen
Great value when buying has the performance of the unit. This parameter is determined by the amount of air that it passes through itself per unit time. The efficiency of the device depends on this. According to the sanitary norms, the whole volume should be replaced in an hour. You can calculate the productivity necessary for your kitchen according to the formula: the area of the kitchen needs to be multiplied by the height of the ceiling, multiply the result by 12 (the air exchange rate accepted by the SES), multiply the result by the factor of the potential stock (equal to 1.3). So, for a kitchen with a ceiling height of 2.5 meters and an area of 6 meters, you need to choose a hood with a capacity of at least 234 cubic meters per hour.
How to choose the right kitchen extractor
When selecting, pay attention to the parameters: type, size, throughput (productivity), control methods, operating modes, presence or absence of filters.
Its width can not be less than the surface of the plate. If the size is smaller, the hood is less sensitive to polluted air. It is even better that the width of the hood exceeds the width of the cooking surface. So, if the width of your plate is 50-60 cm, it is better that the size be about 90 cm, if, of course, you are allowed to design furniture.
Ask the vendor-consultants, in what mode the hood chosen by you can work. This can be an exhaust mode, in which polluted air masses are removed from the apartment, or the filtration mode, when it is cleaned and gets back into the room, as well as its operation in both modes. It is believed that 100% cleaning in the room provides an exhaust mode. But if you decide to buy a filter, it is better to immediately purchase cartridges and change them as necessary.
They can be rough and fine cleaning. Coarse filters detain particles of fat. This is a metal reusable mesh that is washed as it gets dirty. An additional filter is a disposable mesh made of synthetic material. It needs to be changed as it gets dirty, because the grid that has exhausted its resource has a negative impact on performance. Fine filters - coal. They are bought separately. The frequency of their replacement depends on the frequency of work during circulation.
Method of management
Which way to control the cooker hood? It depends only on your personal preferences. With touch controls are activated by pressing a non-convex button. Pushbutton control involves pressing the convex buttons. Control can also be a slider - it is carried out with the help of a mechanical horizontal switch.
Taking a decision, for additional functions: the residual fan stroke, interval inclusion of the hood. The rest of the fan runs for several minutes after it is turned off (from 5 to 15 minutes), which allows you to completely clean the atmosphere of the kitchen. Interval switching enables the device to be switched on for a short time (for example, once per hour or two for 5-10 minutes) at minimum power. This is done so that the tide of fresh air does not stop.
In some, an electronic timer is built in. It should be turned on at the end of cooking, so that the device itself turns off after a certain time.
Almost all devices are equipped with lighting devices. Incandescent lamps, halogen lamps or fluorescent lamps may be used. With incandescent lamps are cheaper, but appliances with halogen lamps consume less electricity. Replace burnt out light bulbs is not difficult.
What determines the efficiency of the hood
The effect depends on many factors.
- From the pressure that creates the motor. If the pressure indicators are high, then the performance will be high.
- From the regime. If it is brought into the ventilation shaft, the work will be more efficient than in the recirculation mode.
- An important role is played by the cross section of grease filters and densities. Than they are denser, the smells are more effectively removed. But remember that not a single carbon filter cleans 100%.
- From the stock of performance. The most effective mode allows you to clean the air under extreme conditions, for example, when food is burned. When choosing, be sure to pay attention to this parameter.
- From the sizes. The larger the device, the larger the area is fence. And this means that there will be no big twists, the sidewalls of the kitchen hinged cabinet will not shrink due to hot air.
Types of exhaust devices
- Traditional or classical
This is a suspended hood, which is mounted on a wall under a suspended kitchen cupboard above the stove. Many manufacturers offer devices with grease filters from acrylic (disposable filters). Such devices operate mainly in recirculation mode. Requires disposable carbon filters that trap small particles. The smell is neutralized only partially. These devices are considered the cheapest.
Devices in which there is the possibility of connecting a corrugated hose are more expensive, but they clean the airspace much better, and coal filtration will not have to be spent so often.
Mount them in a pendant cabinet above the stove. Usually recessed hoods are equipped with a pull-out panel, which increases the working area - the area of air intake. This makes it easier to operate the instrument and increases its productivity. Turns on this extractor in the same mode in which it was turned off. Built in the same are usually equipped with two motors and multi-layer grease-collecting filters. Built-in hoods are not much more expensive than hanging.
- Fireplace (dome)
They do not mount the wall to the ceiling above the stove or the hob. Fireplaces they are called for the dome shape, which resembles a fireplace chimney. They come in three types: metal with glass, all-metal, classical wood or wood-trimmed. The design is versatile, the form can be very creative, for example, hi-tech hoods
Functional features of the device
Modern hoods can remove up to 96% of odors and air pollution that remain after cooking. Especially necessary for kitchen-dining rooms and kitchens, which are combined with a living room. In such cases, it is important that the hood not only had high performance, but also worked quietly enough.
The operation of the device can be estimated as "very quiet" if the noise created by the motor and the airflow is comparable to a whisper (up to 35 decibels). If the noise can be compared with talking at a distance of 10 m (up to 45 decibels), the work of the hood can be called quiet. If your kitchen is isolated (not combined with a room or a dining room), you can not cause any inconvenience to the hood, whose noise level is about 50 decibels (can be compared with a quiet conversation at a distance of 3 m). This noise level is rated as "normal". It is not recommended to purchase hoods whose noise level exceeds 50 decibels. For example, noise of 70 decibels in general can not be ignored: it is comparable with a loud conversation at a distance of about 5 m.
Also evaluate the material of the case. It can be plastic, enamelled steel, stainless steel, tempered glass, aluminum. In the ratio of price / quality, the most attractive is aluminum. The matte surface of this material is well combined with many types of kitchen equipment. The aluminum body does not show fingerprints, it is not corroded and is very easy to clean. The stainless steel case in combination with tempered glass looks very stylish. There are very expensive models, which are made according to the individual order taking into account the wishes of the client.
