How to choose a hood for the kitchen?

We continue to give useful recommendations for the arrangement of your home. This time we will talk about the kitchen, namely about the hood. Everyone understands that most of the time we spend in the house, we spend in the kitchen. First of all, it is necessary to cook food, then to eat and wash after yourself, it takes more than one hour. In the process of cooking, food does not produce the most pleasant odor, humidity increases, combustion products and other factors that adversely affect health are also released. All this can significantly worsen not only the appetite itself, but, in general, the mood. You can also worsen your health, which is already not the best thing in this life. Yes, you can often ventilate the kitchen to eliminate unpleasant odors, but for an ordinary small kitchen, as a rule, ordinary room ventilation is not enough. We gave you recommendations how to choose aerogrill, and now we will give advice on how to eliminate odors.


To keep the atmosphere in the kitchen always at the proper level, the air should be cleaned of all sorts of impurities contained in it.This task is performed by the kitchen hood.


The hood is a block device, which is divided into the main components:


- body of a decorative look;

- one or more electric motors with a fan;

- filtration system for air purification;

- lighting and control unit.


Types of structures



It depends on the location of the planned installation and in which case the hood will be made, as well as several other technological features. All hoods are divided into several types:


1. Island: there is a fixture to the surface of the ceiling directly above the working area. Island hood is placed when the stove is in the middle of the kitchen and does not touch any of the walls. Consequently, the hood and is an "island".


2. Wall (dome or chimney): designed for wall mounting and are considered the most common version of the kitchen hood. They have various forms: a rectangle, a dome, a pyramid and others.


3. Corner: also considered wall hoods. Their enclosures are optimized for installation in the corner of the room.


4. Recessed: can be installed in the lower part of the cabinet above the stove.Typically, these hoods have drawers designed to increase air intake. So in most modern homes, kitchen areas are not large in size, and there is a need to save space, which allows this type of hood.


All extracts are also divided into 2 categories, according to the method of air purification: continuous extracts and circular extracts. Now they make such a type of models, which at the request of the owner can work in both modes.


Circulating hoods can clean the air using a filtration system, after which the air enters the room again, which makes it possible to keep the apartment warm, which is not unimportant in the winter season.


First, the air goes through a grease filter that traps large particles. Filters of this kind are both disposable and reusable. Usually, disposable filters are made of paper, physiceline or synthetic winterizer, after it becomes clogged, the filter is discarded. It will be more economical to use a metal or acrylic reusable filter. After passing through such a filter, then the air passes into the carbon filter, which is also disposable, it must be replaced as soon as it becomes dirty.




- there is no need to arrange ventilation in the building;

- easy to connect;

- heat is stored indoors in the cold season.




- low cleaning efficiency;

- the need to replace the carbon filter as pollution.

Based on all of the above, we conclude that the circulation hoods should be connected only when there is no possibility of drawing the hood to the general house ventilation system.

The flow-through type of cleaning is based on the principle of removing polluted air from the room. Installation of this kind of exhaust is considered more complicated, since there is a need to drill through the walls and make holes for technological purposes to connect to the ventilation system. But it is also possible to note that exhaust hoods with such a cleaning system are much more efficient, since polluted air is thrown out, and a clean one is pumped to replace it.


Flow hoods are equipped with only one filter - grease catcher. This is necessary so that the blades and the walls of the hood do not accumulate a layer of fat, so its presence can adversely affect the operation of the entire device and lead to breakdown.

Types of filters: cleaning, replacement


1. Grease catchers (coarse filters) are one-time type filters, which in turn are divided into 3 types:


- paper;

- non-woven;

- sinteponovy.


On the surface of such grease filters put special marks that can be seen through the protective grid of the hood. When the tags no longer appear, it is time to change the filter.


2. Aluminum filters should be reusable. Once a month, as they are contaminated, the filters must be cleaned with a special degreaser, then washed in a dishwasher. Usually, aluminum filters consist of several layers, therefore, in order to avoid damage to the surface, it is necessary to handle them very carefully.


3. Another type of reusable filter - acrylic. The acrylic filter is washed monthly in warm water with soap. The filter is easily damaged, therefore, it is not recommended to squeeze it.


4. Fine filters, that is, carbon filters - are made of activated carbon. These are disposable filters, they are replaced about once every six months. Carefully read the instructions for use, there must necessarily be specified the exact duration of the filter.


Remember, observations require absolutely all types of filters, since clogged filters can add an additional load, which can lead to a rapid failure of the entire device.


Drawing capacity



Quite an important parameter when choosing a hood for the kitchen is its productivity, that is, throughput. This parameter will be able to tell you how much air the device can process in a certain period of time. Air cubic meter per hour - it is in these units that this parameter is measured. To calculate the parameter, use this formula:


Performance = The multiplicity of the air exchange multiplied by the volume of the room


Therefore, multiplying the height of the ceilings on the area of ​​your kitchen, you can get the volume of the entire room. If you want to calculate a more accurate volume, then subtract the area occupied by kitchen furniture.


The air exchange rate is a quantity that determines how many air changes take place in a given room in one hour. For optimum air exchange, this parameter should be 12.


It is recommended to choose a hood, whose performance is greater,what is necessary in accordance with the calculations, because if the hood continues to function at the maximum of its power, then its service life will be significantly reduced. Also it is necessary to take into account that the hood, working at the maximum speed, can create a lot of noise. The additional load on the device will also fall in that situation if there are bends in the air outlet, and in the case that the filters are dirty. All these points must also be taken into account.


Remember that the formula we cited above has only a recommendatory character. In any case, it is necessary to take into account the features of the kitchen area, as well as the food that they prepare. If you cook mainly food, during the preparation of which there is a release of a large amount of harmful substances, then with the active mode the critical values ​​will increase very much. To avoid this situation, pay attention to those hoods, which have a capacity of 1.5-2 times more than the recommended.


Noise level and dimensions



It is well known that the noise level is measured in decibels (dB). For example, a noise of 40 dB is a rather quiet speech of a person, which can be heard only a few meters away. The noise of 60 dB is a human speech at a distance of one meter.Therefore, the average noise emitted by a working hood is 60-70 dB. That is why, if you stay in the kitchen with a functioning hood for a long time, your mood may sharply decline and your general well-being will deteriorate.


When choosing the size of the hood, you should pay attention to the dimensions of the kitchen stove - should be repelled from this parameter. Hood width should be equal to the width of the plate, or be slightly larger. So the hood can capture the entire flow of air polluted with volatile impurities.


Hood control



The main body for controlling the exhaust is considered an electric motor switch, turning off the lights, as well as regulating the rate of air intake. The last switch is very useful, since it is not always necessary to use the hood to its full capacity. However, with very air saturated with volatile suspensions, you can turn on the “turbo” mode, which is far from being present in all models of hoods.


Just be sure to pay attention to the method of switching: push-button, electronic or touch. The simplest and most familiar button control is considered.There is a whole group of switches located on the front panel of the device. Electronic control is the most expensive type of control hood. With the help of a special electronic unit it is possible to set the required operation mode up to time intervals. In addition, exhaust hoods with electronic control have several additional functions, for example, automatic acceleration of work in case of particularly strong air pollution, automatic activation at the time of the start of cooking, an indicator of filter contamination, lighting activation and much more. Of course, these options add convenience in operation, but you can do without them quite easily.


The touch type of inclusion has the advantage that instead of buttons there are only small switches that start the kitchen hood at a light touch to them. In this case, the buttons are located at the level of the panel itself, which significantly simplifies the care of the surface of the device. Another advantage of the touch type of control can be called the decent appearance of such an extract.


The possibility of a residual stroke is also very useful: the fans can continue their work for another 10 minutes after turning off the electrical supply of the hood. Therefore, the air is cleaned completely.


Also interesting is the option of the hood called “Interval Mode” - in this mode, the hood can be activated automatically every hour. It works at a not very high speed in this mode. This provides additional ventilation of the kitchen.


The cost of kitchen hoods



It is very difficult to specify the exact price or price range, since the cost of kitchen extracts is almost always subject to change. Also on the price can significantly affect the performance of the hood and brand name. But it must be borne in mind that you pay your money not for the image, but for the quality that you should receive from the manufacturer of the goods you bought. But it often happens that model hoods are cheaper to show themselves much better compared to similar models of more expensive manufacturers. It is better, nevertheless, to consult with comrades about whether the work is suitable for them, to ask for some recommendations and to see the extract itself in the work.


In general, the following picture emerges: the simplest kitchen extractor with flow-through air purification and control by means of buttons is in the range from $ 70 to $ 150. In the average price category can be attributed hoods, the cost of which varies from 300 to 400 dollars. Here you will always have the opportunity to choose what you want. But there are also so-called elite models of hoods that have very useful and useless functions, an exclusive design and they cost from $ 1,000. But there are also elite models, with the necessary and unnecessary options, with an exclusive design and cost from $ 1000.
