How to choose a hood for a kitchen without a duct: the criteria for selecting recirculation models

Clean air in the apartment is one of the factors that characterize the level of comfortable living. Kitchen - a kind of critical zone, within which the concentrated pollution arising during cooking. To improve the microclimate in the room, use special cleaning devices. One of the universal options is considered a hood to the kitchen without a duct - a convenient and inexpensive modern device with replaceable filters.

What is attractive for hoods without a duct

If you first decided to purchase a hood, you should know that there are only two types of operation mode:

  • flowing;
  • circulating (recirculating).

To install the first option, it is necessary to equip the tap in the ventilation, so that evaporation from cooking and unpleasant smells go to the mine, and from there - to the street.

Unsuccessful solution for duct mounting

Installation of the circulation hoods without a vent to the ventilation is much easier, since it does not require additional accessories and does not require construction measures. The process of air purification is autonomous, with the help of a set of filters.

Here are a few advantages of the second option, marked by users:

  • ease of installation (possibility of self-installation);
  • compactness (absence of plastic or metal pipes leading to the ventilation opening);
  • care that does not require special knowledge;
  • long service life (7-10 years).

One of the main advantages extends the possibilities of interior design. A feature of kitchen hoods with venting into ventilation is their "attachment" to the ventilation duct, therefore, the choice of cabinet furniture designs is substantially narrowed. Autonomous devices do not depend on the location of the vent, so the plate can be easily placed in any convenient place.


Kitchen without additional communications looks much more elegant

The disadvantages include lower performance than flow models, dependence on electrical power and noise.

Which type of mounting is better

Both flowing and circulating devices can be installed in various ways - depending on the location of fixation and design features. For a standard kitchen set, the formerly the most common hanging devices are suitable. Their place - above the stove, under the shelf or a small locker. The hood is completely in sight, but takes up a bit of useful space.

Now increasingly use built-in appliances. It is more productive and looks much more attractive: the working mechanism is disguised in the locker, and only a beautiful lower surface with a control panel on the front leaves the outside. The cabinet is not fake, since the technical filling takes up a small part of it, and the rest of the space is suitable for storing dishes or loose products.


Built-in hood in the classic interior

The latter type includes corner solutions, specially made for hanging in the corner. Their choice is small, because the angle is not the most suitable place for installing the hob, and therefore there is no active demand.


Angular model in the interior

Along with wall cooker hoods without air duct there are island ones, which you can not do without, if the working surface with the stove is moved to the middle of the room, to the so-called "island". Autonomous devices do not require suspended ceiling structures to mask communications, so many choose them.

Choosing a modern hood: technical specifications

External attractiveness is by no means the only quality that influences the choice. If we talk about household appliances in general, then the first place should be put functionality, which is completely dependent on technical properties. Before choosing a favorite hood for a kitchen without a duct, be sure to read the instructions and make sure the model matches your requirements.

Performance - a guarantee of comfort and cleanliness

The rule is very simple: the higher the productivity, the more effective the cleaning of the air, therefore, the more comfortable the microclimate in the house. But we remember that the filtering samples have a lower indicator than the flow analogs. How to define it?


Formula for calculating performance

We calculate the necessary value, relying on Russian sanitary norms. General formula for all exhaust devices:

room volume (area x ceiling height) x 12 x 1.3 (1.7)

The number 12 indicates the number of changes in the air volume for 1 hour. For flow models, the result obtained must be multiplied by an error factor of 1.3, including loss of productivity due to movement through the air duct, ventilation shaft, etc. For autonomous - multiply by 1, 7, since we take into account the resistance of the filtration equipment.


Table with minimum performance requirements

Suppose that the kitchen area is 8 m², the ceiling height is 2.7 m, so when selecting a hood without a tap with a filter, we are looking for devices with a capacity of at least 367 m³ / h, with a duct - no lower than 337 m³ / h.

How to determine the noise level

The level of noise generated by a working cleaning device depends entirely on its performance: the more powerful the technique, the more noise that interferes with rest. The only way out is to find the middle ground.

Manufacturers try to reduce noise in various ways: they equip fans with acoustic protection, strengthen the case with additional gaskets, create designs that allow air to move freely within communications.


Extractor MaunfeldTowerRound 6 with a normal noise level - 54 dB

Modern models should have a noise figure not exceeding 50 dB. If the instructions indicate values ​​of 40-45 db, you are very lucky - this technique is barely audible, almost noiseless.

Optimum size relative to the plate

We recommend you to choose one of the types of hoods for the kitchen without a duct at the stage of drafting, as the following dimensions will be required for planning:

  • width;
  • depth;
  • height;
  • the minimum distance to the cooking surface.

The width of the product directly affects the efficiency of cleaning: the wider the working panel, the more air it will capture. Ideally, the hood, slightly wider than the slab, should be placed exactly above the slab, without shifting to the side. Common standards are 50-60 cm, but samples from 30 to 120 cm can be found.

Optimal dimensions of the hood

Depth is especially important for embedded models, since it affects the size of at least one module, sometimes all the hinged furniture. Depth values ​​are also typical - from 30 to 120 cm (the largest - for island solutions). There is a rule for selecting a wall dome: it should not be wider than the countertop.

The height is focused on the type of device: for the built-in models it is minimal, for conventional ones it reaches 125 cm. Too bulky products are not suitable for tight 5-meter rooms, whereas in the studio they look more than appropriate.


Installation scheme for the plate

The distance from the appliance to the slab is regulated by sanitary standards and is 65 cm for electric and 75 cm for gas stoves.

Types of filters and care for them

The filtration system provides the process of recirculation: air, repeatedly passing through several layers of different material, leaves on the filters the tiny particles of fat and other impurities that get into it during cooking. Depending on the material and functions, all filters are divided into 2 categories:

  • grease, preventing suspended particles of fat from settling on furniture and walls;
  • Coal, adsorbing microscopic pollution and absorbing odors.

Fat protection is divided into two types: disposable of light polymer materials (sintepon, non-woven, acrylic) and reusable from a perforated metal frame. Synthetic gaskets after use must be disposed of, since after washing they completely lose all the functions of the barrier, the metal can be washed.


Metal grid - a filter of the first level - can be clearly seen from the outside

Durable aluminum or steel mesh is easily removed, and for cleaning they recommend using the same detergents as for metal dishes. It is necessary to use liquid and pasty formulations, since abrasive powders cover the surface with scratches.

Carbon filters are cassettes containing activated carbon inside which is the most suitable component for fine cleaning. After a certain period of use (specified in the manual), the cassettes must be replaced with new ones. Old contaminated parts not only lose the cleaning function, but also reduce productivity, as they increase the resistance.

A set of additional useful features

Models with minimal equipment are cheaper, have a mechanical control and a simplified design. Expensive devices are equipped with pleasant bonuses, useful for housewives spending a lot of time in the kitchen, and for those who rarely look in there.

Lovers of modern technology will appreciate the touch control, in which you do not need to press buttons or sliders, but rather light touch. Sensory products are equipped with electronic stuffing, which allows you to program the operation of the device. The parameters of the mode are displayed on the electronic display integrated in the front panel. To save time and additional ease of use, a remote control is provided.


Extractor Elikor with illumination and electronic control

Another nice addition - the backlight with the function Dimm (more often - white, red or blue), which illuminates the information on the display, and sometimes is an additional source of light. Power adjustment is also useful.

Tips for choosing from the manufacturer:

The choice of recirculation hood for the house should be based on design features and technical characteristics. If you buy a device that matches the size and performance of the room, and do not forget to change the filters in time, you can forget about the unpleasant smells and fatty divorce on the ceiling for at least 10 years.
