Any housewife is familiar with the problem associated with kitchen odors. The aroma of the preparing dinner, tempting in the immediate place of its preparation, may not be particularly appropriate in other rooms of the apartment.
Flour dust, steam from hot pots or splashes of oil, which fried cutlets strive to splatter all around, also do not add health to the atmosphere of the kitchen. In order to somehow reduce the spread of odor, hoods for the kitchen were invented.
A properly selected exhaust hood will easily solve the problem of the spread of kitchen odors
If you just imagine how much foreign volatile substances can form in the kitchen in a year, what room for the emergence and reproduction dangerous microflora on those drops of fat that settle on all surfaces, it becomes clear that the invention of the "hood" significantly improved a life. And this is in ordinary apartments.
What, then, can be said about the kitchens of large restaurants, where only thanks to powerful hoods, kitchen smells do not penetrate into the hall? Thanks to them, everything remains where it should be.
Types of ventilation
In order to choose one or another type of ventilation in the house, you need to remember what it can be:
- Natural.
- Forced.
- Air recirculation combined with air filtration.
A well-thought-out ventilation system for multi-storey residential buildings in Soviet times was a vertical box "piercing" the house from the basement to the very roof. Large cross-section, sufficient length of such air ducts ensured good natural draft and heated house air masses (along with odors) were continuously removed, replacing them with cold air streets.
All kitchens and bathrooms had direct access to the common exhaust system, which was arranged in such a way that odors from neighbors' apartments could not penetrate into the apartment.
Modern, not always justified, aspirations to improve their living space are coupled with such alterations and transformations inside houses, which, at times, violates the entire intelligently arranged system of natural air renewal.
Often, redevelopment in apartments on the upper floors leads to the fact that their neighbors living below you have to choose between the use of industrial air cleaners and what they can create do it yourself.
How does an exhaust hood work?
The whole variety of devices for filtering kitchen air can be divided into two main types:
- Exhaust umbrella. The main purpose of units of this type is to simply remove air into the air duct system, filtering it from dust and grease. Such a kitchen umbrella with a grease trap does not allow the air flow to carry fat particles into the general system. All contaminants settle in a special receiver that requires periodic cleaning.
- Supply and exhaust umbrella. This type of hood not only removes kitchen dirt with an air stream, but also blows clean air into the room.
Types of hoods depending on the type of filtration
The main material from which the hoods are made is stainless steel.
She was preferred due to the following properties:
- durability;
- resistance to moisture;
- resistance to various typical kitchen stains;
- ease of care.
The hood filters are also made of stainless steel (see also article Cooker hood filters: how to make the air really clean). All elements of the "labyrinth" of the air cleaning system, the intake tanks that are part of it, can serve an unlimited amount of time.
Advice! Do not forget from time to time to restore filtering properties to rinse the filters with water to remove accumulated grease and other contaminants.
Exhaust hood options
Kitchen hoods offered to consumers on the market amaze with a variety of sizes, shapes, colors, additional technological characteristics (see also article Cooker hoods - types, principle of operation and maintenance). Their price is also different.
Let's consider some modifications:
- Flat hood:
- The lowest budget option for an exhaust hood.
- It has no outlet to the external air outlet. Only recirculated air mode is available.
- The disadvantage is the significant noise level.
- The filters need to be changed regularly (twice a year).
- Built-in hood:
- "Hides" in the cabinet, hung over the work surface of the stove.
- The air duct from the umbrella to the general ventilation system is hidden inside, without spoiling the overall appearance.
- It operates in two modes - air extraction and recirculation.
- The disadvantage is the additional cost of installing a hanging cabinet.
Built-in model of an exhaust hood
- Dome cooker hood:
- With a modern design, it is suitable for any style of kitchen decoration.
- A huge variety of materials from which the umbrella itself is made, colors and mounting methods.
- It works, like built-in hoods, in two modes (exhaust and recirculation).
- There is a possibility of adjusting the noise level.
- It has the highest capacity among the exhaust units.
- Great for large kitchens.

Features of exhaust hoods
When choosing a kitchen hood, you need to carefully consider all the characteristics and their additional possibilities that can become a necessary and pleasant addition to the direct "exhaust" function of your acquisition.
Basic characteristics
Let's start with the size of the hood's umbrella. The size of the umbrella should not be smaller than the hob. The optimal hood size for a stove, for example, having a width of 50 cm, will be 80 cm. If the store does not have a hood of a suitable size (from 50 to 120 cm), you can always order its production according to a special project.
Optimum height for attaching the hood to the wall:
- for a gas stove - 80 cm;
- for an electric stove - 70 cm.
The level of its noise directly depends on the power of the hood. Constant noise from the ventilation system can negatively affect your well-being. Safe and, therefore, comfortable for humans, the noise level does not exceed 40 dB.
The most modern models of hoods have fans equipped with noise-absorbing devices. The material of the product is also important.
For the manufacture of kitchen hoods, as can be seen in the photos of different hoods presented in the article, high-quality materials are used:
- stainless steel;
- aluminum;
- glass.
An extremely important component of any kitchen exhaust device is a filter, the performance of which determines the effect that will be achieved during the operation of the unit.
Filters are divided into:
- coal;
- fatty.
The most modern filters used in the new umbrella models:
- multilayer;
- removable;
- reusable.
Grease filters, which are equipped with most models of hoods, are made of materials that can be washed with warm water using detergents. These are filters from:
- aluminum threads;
- synthetic materials.
The hood must be equipped with filters.
Then look at performance. The power (performance) that the hood possesses is one of its characteristics.
It is a misconception that some buyers want to buy the most powerful exhaust system possible. It is only necessary to clean the air directly above the working surface of the stove, therefore, when choosing, you should not focus on the total area of the kitchen.
There is no need to purchase an umbrella with a maximum performance (up to 2000 m3/ч). This will only add extra noise in the room, not guaranteeing a more thorough air purification.
Advice! For high-quality air purification in a kitchen of any area, it will be enough to purchase an exhaust hood with a capacity of 600 m3/ч. The main thing is to choose the optimal size and position it correctly on the wall.
Exhaust hood control
When choosing an exhaust hood for the kitchen, you should pay attention to one more characteristic - the way to control it.
There are two options:
- Button control:
- simple and reliable way;
- has a drawback - grease and dirt can settle in places that are difficult to clean.
- Touch control:
- a more practical option;
- does not cause hassle when leaving: just wipe the touch panel to clean it of grease.
Push-button kitchen umbrella control can be a hassle while cleaning
Electronic or touch control is most practical
Kitchen umbrellas work, as a rule, in the following modes:
- air removal (exhaust mode);
- recycling.
Exhaust operation allows the umbrella to remove soot, grease, polluted air arising in during cooking, through a corrugation inserted into a special hole, directly into the shaft ventilation duct.
Unlike houses in which a hole is provided for feeding corrugations, in houses where they do not exist, it is more advisable to use hoods operating in the recirculation mode. In this case, the polluted air, passing through the cleaning on the charcoal filter, returns to the kitchen already cleaned.
The disadvantages of the recirculation mode are:
- low exhaust power, which leads to insufficiently effective air purification;
- the need for frequent replacement of spent carbon filters.
How to install an exhaust hood?
Installation in a private house of exhaust equipment that will effectively remove unpleasant odors and polluted air from the kitchen, creating a favorable atmosphere throughout the house, can help the proposed instruction:
Step-by-step process of self-connecting the hood
- Measure the width of the slab and select a suitable exhaust hood and air outlet.
- Determine on the wall the location of the hood installation directly above the stove, not forgetting that its lower edge should rise 60-75 cm above the hob.
- Cover the plate with thick paper and ensure that debris generated during subsequent work is quickly removed.
- Use a circular saw to cut the air outlet in the ceiling.
- Drill a small hole (10 mm) in the roof strictly along the axis of the resulting opening, using a long drill. This is the center of the duct channel.
- Draw a circle on the roof with chalk, taking the hole in the middle.
- Saw through the roof and the sheathing underneath.
- Install the fan on the hole in the roof: insert its branch pipe into the hole.
- Fasten the flange and seal the perimeter joint well.
- Connect the fan branch pipe with the ventilation duct from below.
- Connect the fan motor to the electrical network.
- Route the wires from the fan to the kitchen (through the ceiling).
- Connect the flexible exhaust duct to the canopy socket.
- Check the strength of all joints, wrap the joints with foil.
- Attach (with screws) the brackets strictly horizontally for installing the exhaust hood, in accordance with the marks made on the wall in advance.
- Hang an exhaust hood on the bracket.
- Connect the fan wires to the electrical network.
Take on yourself only for the installation of small hoods, but the installation of large products should be entrusted to professionals
You can qualitatively install an exhaust umbrella yourself, guided by the recommendations, by watching the proposed video, or you can turn to professionals for help.
Professionals with sufficient qualifications will help to install new equipment so that it meets all safety requirements and guaranteed, exactly for its purpose, performed the function of cleaning the air on your kitchen.
