Cooking in the kitchen is always accompanied by various odors that you want to get rid of. Extraction filters will help to cope with this. It is very important to choose the right filter that suits you, since the timely capture of contaminated air streams and their removal through ventilation systems depends on it. A useful purchase for the home will be a split system, an electric built-in hob, a gas hob, and a humidifier for newborns and children. The rating of the best Karcher washing vacuum cleaners will allow you to choose a similar device.
What is the advantage of buying a kitchen hood with a filter without a drain
Circulating (recirculating) models of hoods are distinguished by the fact that they do not need to be removed into ventilation using an air duct, because the air flow is cleaned by passing through two cleaning stages. In kitchen hoods with a charcoal filter, the polluted air first passes through the anti-grease filter, and then through the charcoal filter, after which it returns to the room.
Kitchen hoods with a filter without a drain are distinguished by the fact that they do not need to be vented
Interesting information! In addition to recirculation hoods, carbon filters are also installed in combined models of devices. A distinctive feature of the models is the ability to start air recirculation, as well as the output of the flow to the ventilation using an air duct.
Despite the fact that recirculating types of hoods require constant filter replacement, which entails additional costs, they are very popular due to the presence of a large number of advantages, among which the following stand out:
- Autonomy. To operate the device, the presence of a ventilation shaft is not necessary, which is especially important in a situation where it is located far from the place where the hob is planned to be installed and you do not want to stretch a massive pipe through the entire kitchen.
- Small size. Hoods with a charcoal filter take up a minimum amount of space above the surface of the stove, they are easy to hide even in a small cabinet. Particularly little space is taken up by sliders, which are extended only for the period of use.
- High-quality air purification without unnecessary ventilation. In winter, when it is cold outside, frequent ventilation will lead to a drop in the temperature in the room, which will entail additional costs for heating. After installing the hood with a filter, frequent ventilation is not required.
- Ease of installation and connection. To use the device, you just need to fix it above the hob, and you do not have to build any decorative boxes or mask volumetric pipes.
- Ease of maintenance. For normal operation, it is necessary to select the correct filters for the hood and change them from time to time; grease nets also require additional cleaning.
Despite the fact that filter hoods require constant replacement, they are very popular.
The price of a charcoal hood is slightly more than the cost of a conventional device connected to ventilation. Among budget models, you can find good options, the price of which is 2500-5500 rubles. The filter needs to be replaced every six months, depending on the application. The price of a carbon filter for ventilation, depending on the model and characteristics, is in the range of 400-1000 rubles.
In addition to a large number of advantages, there are several disadvantages of circulating hoods, for example, low productivity and the need to constantly replace filters. Whether this is a disadvantage, everyone decides for himself.
Cleaning rules
The built-in hood with a charcoal filter without an outlet implies the constant replacement of a component to clean the air. Depending on the characteristics and the selected filter, the latter must be changed frequently. This is a necessary element, which you will not be able to do without.
The aluminum or stainless steel strainers should be inspected once a month to remove soot and grease from their surface. It is best to do this once a week, so the cleaning process will be easy. At the same time, the lattice itself will not have time to overgrow with a new layer of plaque. Manufacturers recommend using a simple method to remove it: remove the mesh and put it in the dishwasher. If the pollution is quite intense, the technique may not be able to cope. In this case, you can resort to household products with an alkaline composition.
Removing various contaminants and vapors harmful to health is the task of the charcoal filter. But the element itself periodically needs cleaning. Laundry soap and ordinary soda dissolve well fats. Alternatively, you can use dishwashing gel, gas stove cleaning compounds.
Procedure
If the hood has not been washed for years, more powerful products will be required. This can be a gel for cleaning sewer pipes. For minor contaminants, it makes no sense to purchase such formulations. Regular soda can easily and easily deal with the problem.
Clean metal filters as follows:
- Remove the hood grill and place in any wide container.
- Prepare the detergent composition. To do this, pour a pack of soda with three liters of water. After that, transfer the solution to a container with a grid.
- Heat on the stove, simmer for about 10 minutes over low heat. If after this it was not possible to get rid of the dirt, boiling should be continued. At the end of washing, rinse the filter with running water and dry. After that, you can put it in place.
Special detergents and gels are used in accordance with the instructions on the package. Usually they are applied to the grid and kept for a certain time. It is better if the hostess goes over the mesh cells with a brush or a plastic brush. Next, you will need to wash it under water and dry it.
Why it is recommended to purchase carbon filters
The work of any hood is based on air purification and prevention of cooking odors in the kitchen. The principle of operation of a charcoal filter for a kitchen hood is based on purifying the air passing through it not only from smell, but also from small particles of dust, dirt and grease. Externally, the device is a rectangular cassette installed in a plastic case. Sometimes in retail outlets you can find options made of synthetic material.
The work of the charcoal filter is to cleanse the air passing through it not only from smell, but also from dirt, dust and grease.
There are also differences between the filters that are used in circulating hoods. So, a cartridge-type filter has an adsorbent located inside. In the case of using a textile filler, the active ingredient is an impregnation. Universal exhaust filters provide a high degree of protection of the air flow from both harmful impurities and hot steam particles.
In a carbon filter cartridge, the active ingredient is small granules of activated carbon or even carbon powder, the main feature of which is the ability to absorb and retain various impurities contained in the drawn air.With active use, the filter on the hood is recommended to be changed at least once every 4 months. The cleaning element is installed immediately behind the grease screen, which protects it from the ingress of large fat particles that can disrupt the operation of the carbon sorbent.
Interesting information! The purchase of a charcoal filter for the hood in the kitchen allows you to make the appliance work efficiently and to establish a microclimate inside the room. And also the constant use of a charcoal hood not only helps to reduce air pollution, but also protects kitchen furniture from plaque and grease particles that form during work in the kitchen.
The active ingredient in the carbon filter cartridge is small granules of activated carbon
Various types of activated carbon are used for the production of filters: stone, peat or coconut. For production, impregnated coal is also used, which is a stone or coconut material treated with special compounds and certain reagents that increase its operational capabilities.
Filters are classified according to their application. So, many companies, in addition to filters for household use, also produce industrial options, which differ not only in appearance, but also in weight. Some models of industrial filters reach a weight of 300 and even 400 kg. Such options for carbon filters are appropriate to install in public institutions and in production.
It is interesting! Some types of carbon filters are designed for installation in waste water treatment plants in order to absorb organic pollutants. They differ not only in the granularity of the coal content, but also in shape, because they can be concave or convex.
The combined filter, in addition to the carbon granule cartridge, has a dense textile layer
What material?
Modern manufacturers suggest purchasing a grease filter for drawing from acrylic, aluminum, special paper. Each of the varieties has features of functioning. So, cleaning of acrylic models is required depending on the intensity of use of the hood. Most often, cleaning is required about once a month, the filters themselves just need to be soaked with a cloth and not wrung out.
The peculiarity of aluminum filters is the need to wash a couple of times a month, using a special fat-free composition for this. The effectiveness of its work will be reflected in the color: if it has changed, then it must be replaced. Layers of perforated aluminum are used to create aluminum filters. The holes are the guarantee that the air will pass as much as possible with minimal noise. It is necessary to wash aluminum products carefully so as not to break thin layers of metal.

The peculiarity of filters made of special paper, non-woven, synthetic winterizer is the impossibility of washing them. That is, if such a filter fails, it only remains to replace it. Replacement is needed when signs appear at the bottom of the product - they can also be seen through the grill. Many manufacturers supply their hoods with a special indicator that will tell you when the filter needs to be replaced in them.
Charcoal filter for hood: what is the principle of operation
Carbon deposits, dust, small particles inevitably appear during the cooking process, and recirculating hoods prevent them from settling on various surfaces. Unlike extraction grease filters, the carbon cartridges can be replaced depending on the degree of soiling.
Another distinguishing feature of them (in comparison with conventional air duct hoods) is the fact that the air, passing double filtration, is not discharged into the ventilation shaft, but returns to the room. This is especially true if a gas boiler is installed in the kitchen, which consumes a large amount of air. During an hour of operation, the device can cope with cleaning from 2.5 to 22 thousand cubic meters of air, and the aerodynamic resistance reaches 120 Pa. It is important to note that for normal operation of the hood, it is required that the humidity in the room does not exceed 70%.
The direct operation of filters for a kitchen hood is provided by turning on the motor, which supplies the air flow to the hood through one or more fans. In this case, the carbon adsorbent is capable of absorbing harmful impurities, and the inner filling of the cartridge also absorbs light ions. In some cases, the degree of filter contamination can be estimated by the increase in its initial mass, as well as by the change in density. In order for the hood to work efficiently, you should constantly monitor the cleanliness of the filter, especially during prolonged work in the kitchen.
The operation of the charcoal filters is ensured by turning on the fan, which supplies the air flow to the hood
The combination filter works slightly differently from the conventional carbon filter. In this case, at the first stage, the polluted stream enters through a dense synthetic textile layer, in which there is a carbon impregnation. Most often, viscose acts as a synthetic textile, on which most of the large particles remain.
After the first stage of cleaning, the second begins, which consists in passing air through the cartridge with carbon granules. The result of this double purification is truly clean air that does not have any foreign smell.
For ease of use, many modern hoods are equipped with special sensors that signal the need to replace a dirty filter. This helps to extend the life of the instrument and to ensure efficient cleaning of harmful particles.
Scope of use of FRIP bag filters
Bag filter "Folter" is used for highly efficient cleaning of highly dusty gas or air from dust in aspiration exhaust systems of various industries, namely: woodworking, metallurgical, construction and chemical industries. It is important to choose the right filter depending on the tasks that will be set for the equipment. Folter ventilation filters of sleeve type are able to cope with polluted air, which is not toxic, explosive and fire hazardous. You can independently select a device of a certain model for capturing explosive dust or a filter that is used to purify high-temperature gases (up to 260 degrees).
Pros and cons of carbon cartridges, differences from grease filters for hoods
There is a big difference between different types of filters. This is due to the fact that anti-grease aluminum filters for extraction are considered to be designs that provide coarse air purification, while after using carbon cartridges, the flow is freed from both large and small air polluting particles.
Aluminum hoods for extractor hood provide only coarse air purification
Important! The main purpose of anti-grease filters is to protect the fans located inside the hood, and the result of the use of carbon cartridges is complete air purification.
The main advantages of carbon filters (relative to ordinary aluminum ones) are considered to be a good work result and high-quality air purification from odors, as well as the ease of replacing contaminated elements.To change the charcoal filter, you do not need to contact a specialist or do not use the device for a long time. You don't have to choose the most expensive filter options. There is always the possibility of purchasing more affordable options that are not inferior in quality to the original cartridges.
The undoubted advantage of using coal systems, in comparison with ordinary grease systems, is the fact that the smells coming out through the ventilation shaft will not irritate the neighbors, since the air does not leave the kitchen.
Among the disadvantages of installing coal systems, one can single out the fact that for the most part they are disposable, in contrast to aluminum filters for hoods, which, as they become dirty, can be washed and cleaned using simple methods. If the carbon cartridge is heavily soiled, the air is practically not cleaned.
The carbon adsorbent of the filter absorbs harmful impurities, and the inner filling of the cartridge absorbs even light ions
Features of installing and replacing carbon filters for hoods
Before installing a built-in hood with a charcoal filter, you should pay attention to the manufacturer's recommendations regarding which replacement cartridges are required for it. This is due to the fact that many firms impose certain restrictions on use and replacement. So, on average, it is recommended to replace the cleaners at least once every 4-5 months, and with infrequent use, it is permissible to stretch the terms up to 6 months.
Charcoal filters for a German exhaust hood are designed to work throughout the year, because reliable adsorbents are used in the manufacture, and the build quality of the device is at a high level. Of course, the price of these filters will be significantly higher than the cost of products of other less popular brands, but the cheaper the cartridge is, the more often it will have to be changed.
Helpful information! Before purchasing additional carbon filters, you should study the technical part of the issue, clarify for what period of use the design is designed. It should not be forgotten that the service life of the filter can both increase and decrease: it all depends on how often and for how long the hob is used.
Manufacturers recommend replacing carbon filters at least once every 4-6 months.
You need to understand that it is impossible to clean the used carbon filter with your own hands, because the main component is finely crushed coal that cannot be recycled. Most often, manufacturers recommend purchasing cassettes of their own production, although there are universal carbon filters for hoods that can be installed in a device manufactured by any company.

Types of hoods with outlet for ventilation. Selection options. Varieties of air ducts. Features of installation.
The purchase of such a product allows you to save time searching for the desired option. After the purchase, it is important to adhere to a certain algorithm to carry out a safe replacement of the part.
How to extend the term of use and is it possible to change the contents of the cassette
The first thing to do before replacing the cartridge is to disconnect the device from the mains and dismantle the air intake mesh. After that, the grease trap for the hood is removed, as a result of which access opens directly to the cassette with the carbon filter.
After replacing the cartridge, it is recommended to turn on the hood for 4-5 minutes to dry the contents of the charcoal filter
Some cassette designs offer the ability to open the case, which allows you to replace content as it gets dirty without buying an entire cassette.To perform this action, after the filter has expired, it is necessary to pour out the dirty filler and fill in new granular activated carbon. The updated cassette is then assembled and reinstalled.
The correct installation of the filter is indicated by a characteristic click. If the installation is not carried out correctly, most likely the device will not turn on. In a similar way, in the future, you can update the contents of the charcoal filter for the hood with your own hands.
In order to extend the life of the cleaning cartridge, experts recommend leaving the device to work for an additional 4-5 minutes after the installation is complete. During this time, drier air passes through the mesh on the hood, and the contents of the carbon filter will dry out, which will prevent it from pressing. In addition to ensuring a longer life of the cartridge, this simple manipulation will help to extend the operation of the hood itself.
To extend the life of the charcoal filter, experts recommend keeping grease nets clean.
Keeping the grease mesh clean is considered another point that can increase the service life of the filter. The cleaner it is, the less likely large particles will get onto the sorbing element. This means that the coal will retain its loose state longer, especially since the anti-fat cleaning process does not take much time. Basic mesh cleaning options:
- wash the part in soapy water or using a good fat-dissolving detergent using a stiff brush;
- pour over with boiling water and grate with a soda-based paste;
- clean with a directed jet of hot air from a household steam cleaner;
- pass through the wash cycle at the highest temperature in the dishwasher.
Users note that any of the methods allows you to make the grease trap cleaner, but the best result can be achieved only after mechanical action on the part with a brush. It should be borne in mind that the installation of the mesh in place should be carried out only after complete drying, otherwise it will quickly clog up again.
Some designs of charcoal filter cassettes offer the possibility of opening the housing and replacing the contents.
When buying a hood, it is additionally recommended to take into account the fact that some models are produced without a grease mesh. Such devices are not advised to choose due to the fact that there is a large load on the carbon filter, which, in addition to small particles, has to filter large, wet and oily particles. All this affects the cleaner and leads to its rapid failure. For this reason, it is better to give preference to hoods with a grease trap.
How to choose the filter that is optimal for the functioning of the hood
For the most part, the charcoal filter is suitable for use in a variety of hood models. Any consultant in the shopping center will help you choose the right option for a specific device. But nevertheless, experts recommend inquiring about the possibility of purchasing and replacing filters before buying a circulating hood, and it is even better to immediately buy several replaceable filters, which will be enough for 1-2 years of use.
Helpful information! When buying a charcoal filter from a source other than the hood manufacturer, pay attention to the box. Most often, a list of hood models is indicated on the packaging, which are designed for the installation of a specific filter. It should be borne in mind that the shape of the filter must be selected depending on whether the device has a pull-out panel or it is a stationary version.
When buying a carbon filter, you need to pay attention to the packaging, which indicates a list of hood models to which the cartridge is suitable.
You should not rely on the fact that a cooker hood with a charcoal filter, regardless of the area of the room, is able to completely rid the kitchen of odor and prevent its spread throughout the home. Recirculating devices, like ordinary ones, are designed to purify a certain volume of air, therefore, before buying, you need to pay attention to what area the device is suitable for in the room. Often, coal hoods, in contrast to flow-through ones, are 20% less efficient.
The choice of a filter element should be done thoughtfully in order to acquire a truly correct design, because it will not be possible to place a synthetic version of the purifier in a place designed for installing a cartridge. Very often, due to the lower cost, users purchase filters made of synthetic fabric, not taking into account the fact that they are not suitable for many models of coal hoods. Even if it is possible to install the structure, the performance of the hood will be significantly affected by this.
Despite the fact that cheaper universal filter systems have been invented, it is still recommended to give preference to the models of the same manufacturer from which the hood was purchased. It is precisely the cassettes designed for a specific version that will ideally occupy the niche intended for them, which will ensure more efficient operation of the device.
Scope of the filter brand SUF
If you are considering Folter air filters, you should pay attention to the aforementioned brand, which is the carbon filter section. The device is designed to clean the air from steam and gaseous contaminants, which can be inorganic, organic and molecular. Among other things, such filters are installed in the exhaust ventilation systems of cafes, kitchens, restaurants and sewage treatment plants.
Main manufacturers of charcoal filters for household use
All companies that produce recirculation hoods for kitchens are engaged in the production of carbon filters. For the convenience of users, filters are made not only for standard rectangular hoods, but also for wall-mounted and corner versions. Depending on the build quality, the work of many hoods is carried out practically without unnecessary noise, which cannot be said about devices with an air duct.
It is not recommended to purchase charcoal filters for hoods of dubious manufacturers.
When buying a model, you need to take into account the number of charcoal filters and be sure to choose options equipped with fat nets for the hood. It must be remembered that the more built-in filters there are, the more you need to buy for replacement, which will affect further waste.
You should not buy cassettes for hoods of dubious manufacturers that do not indicate the recommended period of use of filters. Otherwise, there is a possibility that the hood will not work efficiently. It is necessary that the performance of the filter not only matches the performance of the exhaust fan, but also slightly exceeds this figure in order to increase the service life. For example, if, according to its characteristics, the hood is designed to purify 250 cubic meters of air, and a filter designed for 500 m³ is installed in it, it will need to be changed not after 3 months, but at least six months later.
Important! Before buying a filter, you should make sure that it is suitable for a specific hood model, otherwise the purchase will be useless. And you should also pay attention to the build quality and the availability of certificates from the seller.

It should be noted that filters for Hansa hoods are not considered universal, therefore, before buying, it is better to check with a consultant about their compatibility with a particular device. The high quality of the adsorbents used and the long service life without replacement explain the high cost of one filter - at the level of 1600 rubles.
Which brand should you choose?
Many manufacturers offer to evaluate charcoal and grease filters. We suggest paying attention to the most popular options, which are also attractive in terms of economy. The filter for the crown hood has proven itself well. Most models of modern hoods have indicators that tell you about the degree of contamination of the cleaning element. This means you can always change it to a new one. You can always choose high-quality cleaning elements for KRONA equipment, which will ensure the stability of any recirculation system.The service life of the accessories depends on the degree of use of the exhaust system itself. On average, the kit will work for about 100-130 hours, that is, about six months.
Carbon filters for hoods folter are suitable for cleaning the air - supply, exhaust, recirculation - from contamination in the form of gases, odors. Using these accessories, you can provide high-quality air purification to achieve environmental and sanitary compliance.
Many consumers note Filtero hood filters, which are based on carbon absorbent. Distinctive features of the accessories of this brand are simple installation and durability of work. These cleaning elements show good operational properties, as they consist of a number of components - stone, peat, coconut and impregnated coal and chemisorbent. The filter elements can easily cope with both when installing the hood in everyday life, and in professional models. In addition to their low cost and ease of installation, these accessories attract attention with a high level of filtration, even if the ventilation is not of high quality.
There are a lot of good reviews about filters for ZEMAN hoods, which, in addition to their innovative design, attract attention with a double effect, that is, cleaning the room from both combustion products and smell. This is achieved due to the two-layer filter: the first is made of dense viscose material and impregnated with activated carbon, the second consists of a dense layer of activated carbon granules. This design provides excellent air purification due to its good passage through the filter.
