Features of filters for exhaust

Kitchen air purifying devices are a necessary attribute of any modern home. Small studio apartments suggest the frequent combination of kitchen facilities. Devices called "hood" allow you to exclude the ingress of odors from the kitchen inside the premises. The main components of the hood are several, they all work together. But the most trouble-free technology after a while will require preventive care.


If the universal kitchen filter can be simply washed in the dishwasher, then the carbon filter for the hood in the kitchen will need to be replaced. It is worth considering in more detail the types of existing filters for kitchen hoods. There is a huge number of models from different manufacturers.It can be difficult to understand the differences between the mesh, round water filter. It is necessary to understand the advantages of the combined version of products.

The main varieties can be divided into such two large groups as:

  • grease catcher;
  • coal.

The first options perfectly protect the exhaust and facilitate the task of cleaning the hull. They are made of synthetic base or paper. The last option is a one-time and not to be used twice. Experts do not recommend washing a disposable grease filter for economical housekeeping. Synthetic base filters are easy to clean.

Grease filters are represented by the following varieties:

  • acrylic - these options are not considered durable;
  • from a flizelin or a synthetic winterizer - these options are offered by many manufacturers; recent products are simply replaced as they become soiled;
  • made of aluminum - these are durable options, as the devices can be simply washed with any suitable cleaning agent; this filter is presented in the form of a metal frame, which is quite easy to remove from the device;
  • stainless steel or galvanized - these are fairly common solutions.

Filters in the exhaust device may be several. Some models are supplied with special carbon filters. Experts consider these options best in comparison with other types of products.

Carbon filters have the following advantages:

  • easy installation;
  • small size;
  • simple operation;
  • inexpensive component parts.

In the device itself, there are usually two types of carbon filters, the first of which provides coarse cleaning and the second one is more subtle. Both filters require regular maintenance. Carbon filters look like a cassette element. The cassette includes several cartridges in which the powder coal mixture is placed. Sometimes these are ordinary granules. Carbon filters well remove odors from the air, thereby cleansing it.

Carbon and grease filters in some models are installed at the same time. In the device you can immediately see the grease catchers, and behind them squares. Thus, one device performs a comprehensive air purification. Standardly, models of extracts require replacement of filters once every 3-4 months.Some models have enough annual maintenance. The filter renewal period is related to the level of air pollution in the room.

In order to properly change the filters, you need to study the exhaust device in more detail.

Exhaust installation

The hood in the kitchen can be equipped with an air vent, and it can work without it. If ventilation is provided in the kitchen unit, it will function according to the principle of removing polluted air outside the room. A special diverting sleeve is connected to the ventilation, and the device's engine pumps air into it. Through ventilation, pure oxygen enters the room. Sometimes such a mine combines several rooms.

If a global system is not required or for some reason it cannot be mounted, devices that do not need to be connected to ventilation will be saved. Such devices are called recycling hoods. In fact, they return the same air back into the room, so it cannot be called pure oxygen. Air simply passes through the filtering elements. Devices are considered convenient as they do not require complicated installation.They can be placed anywhere in the kitchen, does not require the mandatory presence of the ventilation shaft. Filters inside the device are simply inserted for replacement.


Disposable fabric grease element in appearance resembles a rug made of thin non-woven fabric or sintepon. Such filters are called flat and usually stand in inexpensive hoods. The more expensive models are reusable products that are made from metal. If the filter has an aluminum or metal filter, the period of use of such a product can be extended for the entire life of the device.

Reusable filters are similar in appearance to a regular grid in a frame. Sometimes many layers of foil are used as a filtering element in such a product. Filtration elements can be perforated or mesh. Holes are not always symmetrically arranged, they may also be asymmetric. The job of the filter is to keep the fat particles on the surface, while the air flows through the perforated cassette freely. Usually popular models of extracts of the average price category,most of them are completed with several small cassettes. They are considered to be easy to clean, as the products are easy to remove and put back.

Not all filter products are multi-layered. Some models of hoods include filters, the base of which is very thin. Cleaning parts made of anodized aluminum are usually presented in expensive models. This base prevents oxidation. To understand the choice of filter is difficult, since many manufacturers offer a variety of models with similar characteristics and at different prices.

What models are better to put on the stove?

Devices in most cases vary in design and size. It is difficult to get acquainted with all possible variants of performance. It is important to understand that an option suitable for one interior is simply inappropriate for another. If the placement of the hood will be competent, it will become a stylish element of the interior.

Depending on the placement option, the hood can be of several types.

  • Wall mounted. Such a device is perfect for placement above the stove, which is installed against the wall. You can install the hood directly into the kitchen.To implement this idea, you can choose embedded or telescopic models.
  • Ceiling. If the stove is installed in the center of the room, then the hood is better to choose the ceiling. Such devices are made in a design performance, therefore, very often play the role of the main element that adorns the room.
  • Corner. Angular placement of plates is less common, so the market offers little corner models of hoods. Due to the small variety of the range, the demand for such products is practically absent. Models are mainly made to order and are single execution.

In the correct choice of those or other options will help users. Opinions of people differ, so when you purchase should understand how this or that device will be convenient to use. The design of the models can be dome or flat. Dome models are quite large, yet attractive in appearance. Often, these hoods make out in the form of a fireplace. Flat designs are considered the simplest options, their installation does not cause difficulties. Usually such models are installed parallel to the plate.

On sale you can find the device T-shaped. It is assumed that the models are fastened to a wide box. The installed structure is considered to be similar to an inverted T. There is another rare variant of island hoods that look like a pipe or a regular box. Such devices are preferred by lovers of style a la minimalism or other modern ways of decorating the premises.

Having defined the design of the hood, it is important not to forget about the parameters of the products. To choose the right size, it is important to focus on the size of the stove or the hob directly. The width of the latter is usually standard - from 45 to 90 cm. Manufacturers of hoods usually offer products with dimensions from 50 to 120 cm. Overall dimensions of the plate and the hood must be correlated. Exhaust with smaller dimensions will not provide high-quality air purification. A large width of the hood is allowed, evaporation from the stove will be well absorbed by the device.

When installing it is important to take into account the height of attachment. Regulatory standards involve the installation of the device at a distance of 0.75 m above the cooking surface.Location according to the regulations will provide the necessary degree of cleaning, as well as safe use of the device. If the hood is placed lower, fat accumulated on its walls may catch fire, which will lead to a fire hazard situation.

How to clean?

The possibility of cleaning the filter from the exhaust hotly discussed by users. Someone claims that it is impossible to wash the products with their own hands, while others suggest washing the filters in a dishwasher. The fact that the grease trap quickly polluted, the hostess know. If the filters are not cleaned for more than two months, then the accumulated fat is really difficult to remove. Layer by layer, the fat gradually hardens, as a result it can only be removed with a coarse brush. Sometimes it is easier to remove the filters with replaceable cartridges and replace.

Some housewives are trying to use a dishwasher as a means of removing grease from the filters, and if everything was not cleaned from the product the first time, the cleaning is restarted. However, not all filters can withstand such a procedure. If the kitchen hood is budget, then the filters built into it will most likely be without special coating.

It is not possible to clean such items in the dishwasher.After the first aggressive cleaning, the filters will turn black and crumble.

If the filter is aluminum, but looks brilliant, it means that it includes a special coating. You can learn about the presence of coating in the passport to the product. Such a filter can be washed in a dishwasher. In general, aluminum objects are not suitable for cleaning in the dishwasher. If aluminum is exposed to an alkaline environment for a long time, the metal will not only blacken, but also collapse. Even if this did not happen the first time, the subsequent washings will still turn black.

In general, the options for cleaning the hood is quite a lot. This should take into account the material manufacturing products. For example, a stainless steel filter is easy to clean from grease soda. But you need to use not dry powder, but soda solution. It is necessary to moisten the cloth and walk on a dirty surface. Another low-cost tool that can help cope with contaminated filters is laundry soap. It contains a large number of alkaline substances that can dissolve even the most stubborn fat.

If neither soda, nor household soap was found in the house, ordinary store-cleaning products will help to resolve the issue.To accurately get rid of the problem, you should choose potent formulations. The hood in the kitchen is well cleaned with professional tools that we usually use to clean the stove. It is clear that such funds will not be cheap. However, despite the fact that the funds will have to spend money, cleaning the filter elements will be exactly reliable.

The composition of high-quality funds, for example, may contain charcoal. Such cleaners will cope well with various types of pollution. Fat deposits dissolve alkaline substances well. These substances can be processed and the hood itself. If you manage to get rid of the dirt, then it will work much more efficiently. It is most convenient to remove the filters from dirt by placing the products in a suitable container. The water in the tank should be quite hot, it needs to be dissolved detergent.

Filters should be placed in the container so that the products are completely hidden in the water. Filters can be left in the detergent for several hours. At the end of time, the product can be cleaned without resorting to unnecessary effort. The cleaning procedure must be carried out with high quality.At the end of the work it is desirable to completely remove the cleaning agent from the filter. If it remains on the surface, it may adversely affect the operation of the entire product.

If you take the habit of wiping the working surface of the hood after each cooking, it will greatly simplify the task of performing a general cleaning. After cleaning, be sure to wipe the filters dry. Otherwise, extraneous odors may occur during operation of the hood. Manufacturers are trying to make modern products from durable and unpretentious materials.
