To maintain a normal microclimate and preserve the decoration of the room in proper form in a modern kitchen, you cannot do without a hood. However, it is not always possible to connect the device to the general ventilation system. In this case, you can bring the duct directly to the street. The ideal solution is recirculating cooker hoods, which is the subject of this article.
What is a recirculating cooker hoods?
There are often cases when the ventilation duct is located too high or far from the hob or the owners do not want to install a corrugation that spoils the interior of the kitchen. The ideal solution for these situations would be to install a hood with a charcoal filter without venting into the ventilation. It is also a suitable option for apartments in multi-story buildings since the diverting device models can provoke complaints from neighbors about the smells that enter them into the premises from the ventilation duct.
What is the name of the hood without venting into the ventilation? It is referred to as a recirculation device. Such equipment is a kind of filter, which, thanks to a multi-stage filtration system, cleans the air from all kinds of contaminants in the form of burning, grease, and odors.
Helpful advice! The installation of a recirculation filtering device is advisable in case of ineffective operation of the ventilation duct or in case of its malfunctioning; in this situation, it is also possible to mount a kitchen hood with an outlet to the street.
The recirculation device consists of a housing, a motor, and two fans, which are located between the filters or on top of them. All internal elements are made of non-oxidizable materials. The performance of the device depends on the power of the engine.
How does a recirculating range hood work?
The recirculation hood is equipped with two levels of protection. The first one is represented by special acrylic purifiers, which perform a rough purification of air from impurities. In addition, non-woven or paper disposable cassettes can be used here as filters. The service life of such filters does not exceed 6 months. New elements can be original or universal. The first option corresponds to the given brand of the hood, while the second one can be suitable for different models. Its cost will be lower, while the quality is also inferior.
At the first level of cleaning, metal filters made of aluminum and stainless steel can be used. This option is more economical since the cassettes do not need to be replaced. For cleaning, the filters are washed under running hot water with detergent, which is performed at least once a month.
Helpful advice! The most effective are metal filters with 5 mesh layers.
The grease filter is an indispensable element of the design, without which the hood will be able to function for a short time. This will happen due to the fact that all the internal parts of the system will quickly become covered with fatty deposits, which are extremely problematic to remove.
The second level of cleaning is represented by charcoal filters. These cassettes are disposable. They are round or rectangular. The inner space of the cassette is filled with an environmentally friendly absorbent in the form of activated carbon. Such filters are able to function effectively for 3-4 months with the active operation of the equipment.
How does a cooker hood work? When the fan is running, polluted air enters the grease filter through the operating panel. Then it goes through the second level of cleaning, where it is freed from odors and small impurities. The purified air is returned to the room through the openings in the device case.
Which is better ducted or ductless range hood?
Considering the question of which hood to choose for the kitchen: with a ventilation outlet or without an air duct, the main advantages of recirculation devices should be studied. Thanks to the two-level filtration system, efficient air purification in the kitchen from various contaminants is ensured. Recirculating hoods often block the exhaust ducts of ventilation, and recirculation hoods exclude the possibility of stagnant air. Such devices are characterized by low noise and vibration levels during operation.
Installing a hood with a charcoal filter in the kitchen without venting into the ventilation is most justified if there is a gas water heater in the room. The operation of the circulating fume hood can provoke backdraft, which increases the likelihood of carbon monoxide poisoning.
Important! The recirculation hood can be installed to clean the air in rooms other than the kitchen, such as a garage.
The recirculation hood is not equipped with an air duct, which saves space in the kitchen. This is especially important for small spaces and does not spoil the interior.
In comparison with diverting devices, such a device is characterized by a laconic and versatile design, lighter weight, which simplifies its transportation and installation. The device consumes less electricity than circulation options. Its operation eliminates the need for maintenance of the ventilation duct.
Air purification with the help of a built-in filtration system eliminates the use of natural ventilation, which will help maintain the temperature regime in the room.
Disadvantages of recirculating range hood?
When choosing such a filtration system for the kitchen, one should take into account the disadvantages of the device. For efficient operation of the hood, it is necessary to periodically change the filters, which entails additional financial costs. In addition, for some models of hoods, it is quite problematic to find the necessary accessory.
With sufficiently strong air pollution, the purification system may not cope properly with the function assigned to it. In this case, it is possible to envisage a combined type of kitchen hood, which operates in exhaust and recirculation modes.
Helpful advice! It will allow you to save money by making a charcoal filter yourself, which is possible for some models.
The operation of the recirculation hood does not promote proper air exchange in the kitchen area. Therefore, in the case of installing a gas stove, a continuous flow of fresh air should be ensured, which eliminates the likelihood of carbon monoxide poisoning.
Recirculating devices without venting into ventilation are characterized by an efficiency of 70%, which is lower than that of circulating hoods. In addition, the price of coal filtration systems is much higher than the cost of other analogs.
Types of recirculating range hoods
Based on the type of casing, hoods with a filter without exhausting into the ventilation duct can be horizontal, vertical, inclined, and telescopic. The first option is located parallel to the hob. For vertical devices, the filtration surface will be located perpendicular to the plate, as a result of which it will take up more free space.
The inclined version is located relative to the slab at a certain angle. This hood is characterized by efficient and quiet operation. Thanks to its convenient location, it saves space in the kitchen. A telescopic device is a type of built-in hood. The working surface of the device is pulled out if necessary, and after the end of the work, it returns to its place.
According to the installation option, there are the following types of hoods for the kitchen without venting into the ventilation: suspended, built-in, and island. The first type of device is fixed to the wall. The second option is installed inside the kitchen unit. Such devices are characterized by lower performance. Island devices are located at some distance from the wall and are attached to the ceiling.
Based on the design features, hoods are stationary and retractable. The latter option draws in steam over a larger area. This improves the efficiency of the device. Recirculating hoods can be flat, domed, and curved in the shape of the body.
The recirculation hood housing is often made of stainless steel or aluminum. Such options look harmonious in kitchens decorated in modern and high-tech styles. The surface of the products can be enameled. This option has a low cost. These hoods are easy to maintain.
The most expensive devices are made of tempered glass. Such devices have a stylish look. However, the hoods need careful maintenance, since the material is rather fragile, which brings inconvenience to the operation of such equipment.
How to choose a ductless range hood
When deciding which hood to choose for the kitchen, you should first study the operational characteristics of the devices. An important parameter is the power of the device, which is in the range of 150-350 W. It is selected depending on the size of the room. You should not purchase a device with low power for a large room, which simply will not cope with the task at hand.
It is also not recommended to give preference to a model with high power, exceeding the optimal value for a particular room. Such a decision is economically unjustified since electricity costs will increase. In addition, a more powerful kitchen hood is characterized by an increased noise level.
The performance of the device is selected based on the intensity of the load on the hood. For a small family in which simple meals are prepared, a model with an indicator of 200-300 m³ / hour is sufficient. For large families who eat a variety of foods, hoods with a capacity of 300-400 m³ / hour are suitable. For those who cook a lot and often, it is necessary to give preference to models with a capacity of 500-600 m³ / hour.
The noise level is of no small importance, which determines the comfort of using the device. The optimal figure for a small space is 45 dB. For a spacious room, this parameter can reach 55 dB.
The size of a cooker hood with a charcoal filter without venting into the ventilation must correspond to the dimensions of the hob. The ideal option is a model, the dome of which will protrude 10 cm beyond the slab. The backlit model is convenient to use.
What should I look for in a ductless range hood?
It is advisable to choose a quality device from a trusted manufacturer, which has proven itself in the home appliance market from the best side. An important nuance is the type of filters that are used in the system. The degree of distribution of cassettes depends on this criterion since they must be changed periodically.
The material used for the manufacture of the hood with a charcoal filter affects the particulars of the device’s care. The most capricious equipment is made of tempered glass.
Some hood options are equipped with a function for changing the speed mode. This option allows you to adjust the intensity of filtration depending on the type and amount of food that is being prepared in the kitchen. This helps to reduce energy costs.
Hoods for the kitchen without venting into the ventilation can have a mechanical or electronic control panel. The first option is presented in the form of buttons or sliders. Push-button adjustment is popular because it is more convenient. The slider setting is not very reliable and can start to jam after a while due to the accumulation of fatty deposits.
Helpful advice! Some modern models for ease of use are equipped with a filter clogging indicator, remote control, an option to automatically turn on and off the device, a timer, a clock, which increases the cost of the device.
Hood models with an electronic panel are characterized not only by the ease of use but also by increased cost. The command can be given both by means of a touch screen and by means of remote control.
Recommendations for installing a kitchen hood without a vent
The functionality of the exhaust system directly depends on the correct installation of the device, which should be carried out in strict accordance with the instructions. The equipment is predominantly fixed to walls and ceilings. Before installing the appliance, it is necessary to check the strength of the base to exclude the possibility of falling. If the device is to be installed in a cabinet, it must be prepared in advance.
A kitchen hood without venting into the ventilation must be located relative to the hob at a certain distance, which is normalized by current rules. It is necessary that the device is at a height of 75 cm above the gas stove, 65 cm above the electric one.
A 220 V socket should be installed near the hood. The device should be positioned in such a way as to provide free access for the purified air outlet.
According to the instructions, holes for fasteners are made in the base with a drill, which is fixed with dowels and screws. Then the device is hung on the fasteners, after which it is connected to the electrical network. After installation, it is necessary to check the functionality of the hood without a branch.
How do you clean a ductless range hood?
Coal cooker hoods need to be looked after regularly in order to work effectively and efficiently. The grease filter, as it gets dirty, needs to be removed and washed with special detergents.
Important! When performing any preventive procedures, the hood must be de-energized.
The carbon cartridge should be replaced periodically. The frequency of manipulation is related to the intensity of use of the device and the characteristics of the model. To replace the filter, it is necessary to pull out the grease mesh from the device, then remove the cassette. After that, the element is replaced with a new one, which is mounted on a seat with subsequent fixation. Then the grease filter is put back in place.
You can use a universal option that fits the size of the worn element. Some filters, as they become dirty, just need to be washed under running water and dried, and then reinstalled. This remanufactured accessory is only offered by Elica. Depending on the model, you can simply replace the cassette filling or make your own cleaner.
To make a homemade filter for an exhaust hood without a drain, you will need a pad of padding polyester and activated carbon in tablets or granules. A filter is cut out of the blank on the basis of the pattern of the old product, which consists of two pieces. Carbon filler is placed between the sheets of padding polyester. The finished filter is inserted into the cassette.
Some models of hoods are equipped with charcoal filters covered with a protective fabric layer. It can be removed and washed and then reused. In such cassettes, it is easy to replace the carbon filler, which is poured between the tissue layers.
Important! Possible manipulations with charcoal filters depend on the hood model and on the manufacturer’s recommendations, which are set out in the instructions.
