Who doesn't like to sit in the kitchen over a cup of tea? And if your beloved wife cooks there, then watch this and chat about the day. The kitchen must have a comfortable environment. Unpleasant odors and gas decomposition products can ruin your time on it. And if people have a studio apartment? Life in it without a hood is simply unthinkable! Simple ventilation (natural ventilation) cannot solve this problem. For the purpose of eliminating discomfort, an exhaust hood should serve, which will help to remove the exhaust air.

All kitchen hoods are divided into three types.

  • Circulating (diverting). They are directly connected to the duct pipe.
  • Recirculating. Their principle of operation is to purify the air using special filters.
  • Combined. They are equipped with both filters and an air duct, which allows them to work in two modes. They are rarely used.

In some situations, a circulating and combined ventilation design is not possible. It so happens that the air duct is located too far or high from the hob. Sometimes people just do not want to mount the corrugation, which can spoil the interior a little. In a multi-storey building, installing a circulation hood model can provoke a complaint from neighbors about smells coming from your kitchen to their ventilation. In this situation, you can use a special autonomous hood without exhausting air into the ventilation.

Principle of operation

Using a reliable multi-stage filter system, this device cleans the air from various kitchen contaminants: odors, grease, and burning. At its core, the device does not extract air from the room, but is its filter. The recirculation hood consists of a housing, a motor itself and fans, of which there are always two. They are located inside the top of the filters or between them. The working performance depends on the power of the electric motor. When installing such a system, it is necessary to provide for the nearest location of the 220 volt outlet. The internal parts of the hood are made of non-oxidizing materials.

    Recirculation hoods for the kitchen are used in the following cases:

    • the hob is located very far from the ventilation hole and it is not possible to dismantle the pipes;
    • ventilation cannot be used directly due to its deterioration;
    • unsuccessful, too high location of the ventilation hole.

    Since the device has a whole complex of protective filters, the hood is also called filtration. It has two levels of protection. The first level of coarse cleaning is a special acrylic cleaner. Their main component is an acrylic filter. This also includes models with paper or non-woven disposable cassettes. The disadvantages of acrylic and paper filters are that they are single use only. Their service life does not exceed six months. Also, filters made of metal (aluminum, stainless steel) can be attributed to the first level of purifiers. They are more cost-effective as they do not require replacement. It is sufficient to wash them thoroughly with hot water and soap once a month. It is better to choose those hoods that have at least 5 layers of metal mesh. A smaller amount will be ineffective. The second level is characterized by a hood with charcoal filters.Coal is a well-known environmentally friendly natural absorbent.

    Unfortunately, carbon cartridges are also disposable.

    Electric hoods differ according to the type of housing.

    • Horizontal. Their geometry is the parallelism of the hob.
    • Vertical. The filter surface is perpendicular to the plate, which takes up a lot of space. For such systems it is necessary to have a very large kitchen.
    • Inclined. As the name suggests, they are located at an angle to the slab. They have a number of advantages, as they work efficiently and quietly, and they also significantly save space.
    • Telescopic (cassette). A type of built-in hood, which, if necessary, extends, increasing the suction surface. After finishing cooking it can be pushed in.

    According to the installation method, they can be as follows.

    • Suspended. They are wall-mounted and usually contain a hinged add-on panel to increase the usable filtration area.
    • Built-in. They are mounted inside the kitchen unit. They are very compact, but have low performance.
    • Island. Serve for those slabs that are not located close to the wall, but at some distance.

    There is also a difference in the material from which the case is made.

    • Metallic (stainless steel, aluminum). They are usually performed in a high-tech style. When using them, you can emphasize the modern style of the interior.
    • Enamel. These appliances are easy to clean and maintain. The most inexpensive representatives of the range of hoods.
    • Strained glass. Very beautiful models that require gentle care. They are easy to beat, which brings some inconvenience to the use of this technique.

    Advantages and disadvantages

    Based on numerous reviews about the operation of hoods without venting into ventilation you can determine the main advantages of this type of system.

    • Two-level air filtration very well cleans it from various household pollutants.
    • This type of hood operates at extremely low noise and vibration levels.
    • Conventional hoods partially block ventilation ducts. The recirculation hood will allow you to clean the air without stagnation. It will complement the ventilation system.
    • If there is a gas water heater in the apartment, the use of a conventional hood will create a reverse draft, which is very dangerous and can cause carbon monoxide poisoning. To avoid such an accident, it is necessary to use a hood without air extraction.
    • At the request of the client, such a hood can be installed not only in the kitchen, but also in any room, for example, in a garage.
    • It does not take up much space, which saves space for other irreplaceable elements of the kitchen interior. This is especially important for small kitchens in modern apartments.
    • These devices are very lightweight, which is a plus for both delivery and installation.
    • Recirculation hoods have a more laconic and versatile design compared to conventional systems.
    • Installation of such a structure is much cheaper than installing a system with an air duct.
    • These devices are much better at eliminating unpleasant odors. They will not be able to get to neighbors through the ventilation duct if you live in an apartment building.
    • Cleaning with a filter allows you not to use natural ventilation for a long time, which preserves the temperature regime of the dwelling. You don't have to use heaters or split systems again.
    • The appliance consumes a small amount of electricity.
    • With such a device, there is no need for maintenance of the ventilation duct.
    • The price of such devices can pleasantly surprise the buyer.

    Together with obvious advantages, such a filtration system has a number of disadvantages.

    • Filters must be replaced regularly. In addition to the fact that this is an additional financial waste, you need to spend time on this work.For a large family, this can be a real problem, as frequent cooking increases filter consumption. Also unlucky for lovers of fatty foods and fans to smoke under the hood. Such things will shorten the life of the cleaning system.
    • Filters for the system are difficult to find, despite the presence of numerous analogues.
    • If you accidentally delay replacing the filter, the hood may fail and require expensive repairs.
    • Recirculation hoods are sometimes more expensive than conventional hoods.
    • The design of such devices is less varied than conventional hoods.
    • If the air pollution is strong enough, the filtration system may not be able to cope with its purification.
    • Compared to classic air extraction hoods, the efficiency is not so high and amounts to about 70%.

    How to choose?

    By choosing a recirculating hood, the following points must be considered.

    • The power (performance) of the system must match the dimensions of your kitchen. In a private house, the size of such a room can be significant. If you choose a device without access to the roof with a lower power, air purification will be insufficient. In order to correctly select the required power, it is necessary to carefully study the technological passport of the selected product. The appropriate dimensions of the room should be spelled out there. You should not choose a hood with a power that is much higher than the required one. This will increase energy costs and significantly increase the noise level in the room.
    • Measure your hob before purchasing any appliance. The cleaning dome should ideally protrude 10 cm beyond the hob.
    • It is better to choose a hood with illumination - this is very convenient for a good housewife who spends a lot of time in the kitchen.
    • Explore the prices for the types of filters applied to the selected device. Since they must be replaced, it is best to immediately pay attention to whether you can update them regularly or is it better to choose a cheaper option.
    • Choose a means of care for the metal parts of the hood and its body. Calculate their cost. For example, special care is required for tempered glass hoods, which will require additional waste during the period of operation.
    • Find out which models have the ability to change the speed limit. The purchase of such a system will allow you to adjust the intensity of the filtration process depending on the amount of food prepared. This will help you save energy in some cases.
    • Modern models have additional options like gadgets: electronic touchscreen display, timer, clock, temperature indicator, automatic switching on of the device, remote control. If you need these functions, then choose a range hood with them.
    • Read customer reviews online. Perhaps it is they who will help you decide on the choice of the device.
    • It is important to remember that the more functions the presented technique has, the higher its cost.
