The air into the car's salon comes from the environment all the air ducts to maintain a sufficient amount of oxygen inside the driver for the driver and passengers. In a dense flow of machines, the air is sent to the vehicle in a mixture with exhaust gases, coming from the car of the counter car. To breathe in such air is unsafe, and a cabin filter is installed for harmful impurities.

Why need a cabin filter in the car

Many drivers underestimate the importance of the element filtering the air that enters the car's salon. According to research, the cabin filter is able to hold up to 99.5% of harmful impurities contained in the incoming air. In the absence of a filtering element, the driver and passengers have to breathe fuel combustion products containing: soot, nitrogen oxides, sulfur and carbon, heavy metals, aldehydes and more than 200 other substances harmful to the body.

According to the research of environmental monitoring services of the situation, in large megalopolis, air pollution on roads exceeds 20-40 times established norms. Conducting in a car for several hours a day, the driver risks to get chronic respiratory diseases and nervous system. In addition to the impact of toxic substances, the harm to the respiration to the driver's breath of dust from tires, soot, asphalt and other things are applied.

In addition to preserving the health of the driver, the cabin filter performs a task to slow down the outage of the machine. Do not pass into the salon dust and nothing, the filter element allows you to prevent winding glass.

How often to change the cabin filter

There is no unambiguous answer to the question of how often it is required to replace the cabin filter. Each manufacturer of the car establishes its recommended time for replacing the filter element, which, in most cases, range from 20 to 25 thousand kilometers of the machine. It should be noted that these values \u200b\u200bare specified for European cities, where there is better with ecology than in large Russian megalopolis. Russian specialists in the field of ecology recommend drivers to change the salon filters every 10-15 thousand kilometers.

Since it is difficult to navigate on such scattered recommendations, it is easier to determine the clogs of the salon filter according to explicit symptoms:

• When the air ventilation system is turned on in the cabin, dust appears;
• During the movement of the car in the cabin, there was a unpleasant smell;
• Glasses began to move often from the inside.

If the listed problems are concerned, the correct solution will be removed the cabin filter and make sure it is contaminated or clean.

Important: The dirty cabin filter has a negative effect on the air in the cabin. Over time, harmful bacteria, fungus and mold develop in the filter. If the filter does not be able to hold the trace elements due to contamination, they will begin to enter the salon, providing a negative impact on the health of the driver.

Where is the cabin filter

Car manufacturers can install a cabin filter to various locations of the cabin, but they try to take into account the fact that the filter element has to be changed quite often, respectively, access to it must be lightweight. Definitely tell where the cabin filter is located only the book on the operation of a specific car model, in which this information should be displayed.

Most often, the cabin filter is installed behind the glove compartment or under it. You can find cars in which air entering the interior element is installed on the driver side, for example, under the dashboard. Some machine manufacturers put a filter at the air inlet, that is, they have it under the hood in a special case or recess, in which case it is simple to replace it.

How to replace the cabin filter

The cabin filter is very easy to replace, it is enough to detect its location in the cabin of the car and get to it. It is important when removing plastic inserts, followed by a filter element in the cabin, not damage the latches on which they hold. It is better once again to look in the instructions on the car, how the mount is removed than to restore it or completely change the item due to breakdowns.

After driving the old cabin filter, do not hurry to install a new one in its place. It is recommended to spend spelling or otherwise clean the location where the filter element was installed. Next, set the item to the place of the old, paying attention to the pointers on it, which will prompt which side to insert the cabin filter correctly.

Types of salon filters

Choosing a filter, first to be guided by its size. Depending on the car model, the size of the cabin filters differ, and on the package with the consumable element, manufacturers indicate for which machines it is suitable. At the same time, salon filters differ not only in size, but also by materials from which they are made.

Replacing the cabin filter is not only concern for the health of passengers auto, but also the extension of the operational resource of the air conditioning system. Timely replacement increases the intersavice air conditioner service intervals, which saves your time and means.

Do not ignore

Many drivers completely forget about such an important component of the car as a cabin filter. As they say, "does not affect the speed", with which it is impossible to argue. Despite the fact that the technical characteristics of the car do not change at all, the dirty cabin filter has an indisputable detrimental effect:

• reducing the filter ability of the paper element. Therefore, the air absorption requires greater effort, which leads to an increase in the load on the stove motor;
• the formation of bacteria that are spread over all air conditioning. Especially on the evaporator, because there is the most favorable environment. As a result, you will have to make the disinfection of the entire system more often. It is worth considering that if you do not want to spend, then the cost of cleaning a hundred times will exceed the cost of the timely replacement of the paper cleaner.

How to understand that the filter is time to change

Manufacturers recommend changing the cabin filter at least every 12-15 thousand km or once a year. If you are operating a car in a dry climate with a moderate dust content in the air, the replacement intervals can be slightly increased. If you are unknown information about the installation date, the following symptoms can be a signal for replacement:

You can always pull the filter and estimate the status of the filter element.

What filter is better to buy

New elements can be only two types: ordinary and coal. The traditional antique filter, which can be recognized on the natural white color of the filter element, delays only mud particles and dust.

Paper element of the coal filter is additionally processed by activated carbon. Such a cabin filter delays not only dust and dirt, but also some malicious chemical compounds. The molecular structure of activated carbon allows you to choose hydrogen sulfide, hydrocarbon, carbon monoxide and sulfuric gases. Manufacturers assure that such filter elements help clean air from exhaust and unpleasant odors.

If you want to buy a cabin-type cabin filter, be sure to check the catalog, whether they are produced for your car model. Each cabin filter is designed for the specific dimensions of the plastic box. For better sealing, the edges are compacted by a foam stroke. In case of failure, measure the original filter, in order to try to choose an analogue.

Where is

There are only two locations of the air purifier:

• in the windscarette space behind the engine shield. Very often, the space near the flashes is covered with a plastic cover;
• in the car inside the torpedo. In this case, it may require not only a screwdriver to replace, but also some degree of predisposition to gymnastics.

Before replacing the cabin filter, refer to the repair manual and the operation of your car. It will help you not only to find out where the salon filter is located, but also prepare the entire necessary tool. For example, we will consider several cars at once with your own hands.

How to install

Some manufacturers plants indicate the method of installing the filter element. It will be an arrow indicating the direction of air flow. If the arrow looks down, the air flow is sucked from above.

If there are no marked signs on a new filter, determine which side of the "groove" is greater depth. This will be the party through which crude air passes. The logic is that deeper grooves allow longer to collect large garbage, leaves.

Toyota Corolla (140/150)

In Tyta Corolla, the air filtration system is behind the glove box at the passenger legs. To replace, you do not need anything other than the new filter element.

At the top of each side of the glove box are latches. If you deduce them, the druel box will slightly drop out, which will open access to the filter housing. The housing is kept on two latches. After compressing them, nothing will not interfere with installing a new filter element.

If the glove box dropped during the installation further, inspect the microlift drive (this small piston is responsible for the smooth opening of the glove). Perhaps he just jumped out of his attachment.

Chevrolet Cruze

Replacing the cabin filter on Chevrolet Cruz:

• on the sides of the inner space of the glove box, you need to remove two latches limiters. It needs to be a little bend, and then pull to himself;
• on the right side, remove the stroke limiter;
• after lowering the box, you will appear view on the plastic cover of the filter element;
• replacing the cabin filter is possible after removing the lid (it lasts 3 latches).

Daewoo Lanos.

Replacing on Lanos is carried out from the boost space. You will need:

• remove the rubber compactor of the windscarette;
• unscrew 3 fastenings of the left side of the jab (plastic, from which wipers stick out). After pulling it a bit in the direction of the near wing and pull out;
• slide your hand in the opening to felt the top of the filter element. The new salon filter is installed at the place of the old.

In the case of Daewoo Lanos, you really have to show twice.

The daily operation of the car requires the correct and reliable operation of all its mechanisms. In this case, we will talk about the filtering systems of the machine, each of which performs important, but different tasks. The similarity and difference between the salon and air filters, the mechanism of their work, replacement and installation will be discussed below.

This air purification element is in every modern car. The cabin filter has long been not a luxury that wealthy car enthusiasts can afford. The air quality in the cabin depends on this filter, the intensity of the blowing, a decrease or complete removal of the concentration of harmful substances (nitrogen oxide, carbon monoxide, dust). Depending on the design of the filter element, the cabin filters are divided into cartridges and cabinets.


Cartridge filters are most popular among motorists, since it allows you to change the used plate (cartridge), and not a completely precast filter (housing with fastening and cleaning item). The cabin filter is located behind the glove compartment, most often closer to the driver's place. A little less often installed right under the hood - it is typical for many European cars.

It is located in front of the "stove", so the purified air through the damper system will flow directly into the car's salon.

The cabin filter can be coal or simple, depending on the materials located on the plate. A simple filter consists of a conventional polypropylene, which delays dust and cleans the air from odors. A coal version will be more efficient - activated carbon placed between the layers, perfectly copes with unpleasant odors and purifies air from chemicals. But the price of the carbon filter will be noticeably higher.

The frequency of replacement of the salon filter can be different, but not less than once a year. A certain kilometer (15, 20, 50 thousand km.) In this case, the landmark is also very conditional. Bad operation of the heating system, unpleasant smell, fogging glass from the inside of the cabin, scored by mud and dust plate of the filter element - these are the main signs of the wear salon filter.

Air filter is an important element in the car. It is intended for cleaning the air entering the engine, and also adjusts the temperature of the combustible mixture in gasoline vehicles. Filter wear can lead to a drop in engine power, increase fuel consumption and increase the concentration of harmful substances in the exhaust.

The air filter may have a different shape (panel, in the form of a cylinder and not having a frame, or frameless), and the effectiveness of a filter is determined by the number of air purification stages and dust fence system.
The multistage system allows you to better clean the air from trace elements capable of damaging the engine.

Dry dust fence is more effective compared to oil systems, so their distribution is quite explained. They are easy to replace, although they have a rather complicated design, which includes porous cardboard, various light metal and polymeric substances. The percentage of passed particles in dry air filters is very low and does not exceed 1%, while the oily systems can "not notice" 2-3%.

The need to replace this element occurs during the operation of the car, directly related to the mileage, and the appearance of the filter will be an additional factor that influenced the solution. On cars with a diesel engine, as well as with engines equipped with turbocharged, replacement of the air filter occurs even more often.

Similarity and differences

Air and cabin filters - elements very similar on the principle of operation and end result. Both cleaned air from dust, dirt and other trace elements. The air filter has a more complex design than saloon - at the same time the air filter is enough variable depending on the particular car, while the cabin is more universal in use. These items are not directly related to each other, but work separately from each other. But if the air filter serves for the correct and safe operation of the engine, the cabin filter provides comfort and clean air for the driver and passengers.

Many car enthusiasts are quite scrupulous to the issue of maintenance of their car and in most cases they even understood well in the device and the principle of operation of its main aggregates. However, there are a number of secondary details and systems that car owners do not pay due attention, considering them insignificant. For example, almost any owner of the machine will certainly take care of the timely replacement of the air filter, which is part of the engine inlet system. But about the need to replace the filter element responsible for cleaning the air cargo entering the interior, often forget. Some of the drivers do not recognize at all about its existence, until they get acquainted with the maintenance regulations. So, in this article, let's talk about the automotive salon filter.

Before you begin to consider the design and scheme of the work of modern cabin filters, we briefly remember the history of these air purifiers. Interestingly, they began to be applied much later than classic air filters designed to clean the flow of flow in the intake manifold. The awareness of the need to filter the air inwards came in the late 70s - early 80s, when the number of vehicles began to increase rapidly and began to appear first plugs, around which cloud from the exhaust gases were literally created. For the first time, the cabin filter was installed on the serial car in 1991. It was a filter paper that captures particles of more than 5 microns, and was powerless in the fight against toxic gases. In the second half of the 90s in Europe, the salon filters have become massively installed on cars of the average price category. These were already advanced filtering elements with the addition of activated carbon capable of absorbing the molecules of harmful substances, such as nitrogen oxides, sulfur and others. Currently, the cabin filter is an integral attribute of most cars. Only some budget models, and then, as a rule, in primary configurations, do not provide for the installation of such elements for air filtration.

Purpose of salon filter

Above, we have already noted that the interior air filter is designed to remove various kinds of harmful substances penetrating into the inner space of the car through the air ducts of the ventilation system. Many will probably become a matter - why pay great attention to air filtration if it enters the salon not only through the air intake, and also through the gaps in seals and simply when opening the doors of the car. This is true, however, the excess of the concentration of human-hazardous substances is characteristic only for the zone of intensive movement, when the flow of transport is quite dense and the speed of its movement is small. In this situation, the exhaust pipe of ahead of the vehicle is almost closely adjacent to the air intake moving along the car. It is in direct proximity to the exhaust system of the exhaust gases, the permissible norms of the concentration of harmful components can be exceeded 10-15 times. If you make measurements a few meters from the car operating on the outdoor, then there will be an excess or insignificant here, or it will not be at all.

In addition to toxic substances, the cabin filter of the car must capture dust particles, soot, rubber. These particles are quite large and problems with their screening usually do not occur even from the simplest filtering elements, so they will not stop on them, and it is better to pay attention to more difficult-to-boring products.

Exhaust gases contain a whole wipes of harmful compounds, at a certain concentration of negative impact on human health. We are talking both about the momentary consequences like headaches, involuntary sneezing and cutting in the eyes and the danger of serious chronic diseases in the future. The maximum permissible concentration of adverse chemicals is determined by the standards of GN 2.1.6.1338-03, which set the maximum one-time and average daily concentration, as well as the hazard class of each of the substances. The table below shows some of the harmful components indicating the MPC in atmospheric air.

Substance	Chemical formula	Hazard Class	MPC one-time, mg / m 3	MPC average daily, mg / m 3	Physiological action
Carbon oxide (carbon monoxide)	Co.	4	5.0	3.0	Oxygen starvation, leading to the occurrence of headaches, shortness of breath, reducing the velocity of psychomotor reactions
Nitrogen oxide	No.	3	0.4	0.06	Defeat of the respiratory tract and lungs
Nitrogen dioxide	NO 2.	2	0.2	0.04
Benzapiren	C 20 H 12	1	—	0.1 μg / 100 m 3	Carcinogen, can accumulate in the body
Hydrogen sulfide	H 2 S.	2	0.008	—	Dizziness, headache, nausea
Benzene	C 6 H 6	2	0.3	0.1	Carcinogen, can cause headaches, nausea, dizziness.
Carbon black (soot)	C.	3	0.15	0.05	Carcinogen
Formaldehyde	CH 2 O.	2	0.05	0.01	Carcinogen, negatively affects the respiratory tract, mucous membranes, nervous system
Methane	CH 4.	—	50	—	Oxygen starvation at high concentrations

The most dangerous of the above substances is carbonated gas - a colorless poisonous compound, devoid of taste and smell. This gas is formed as a result of incomplete fuel combustion, causing strongest poisoning at large dosages. In traffic jams, the permissible concentration of CO can be exceeded several dozen times, and, most unpleasant, almost none of the types of cabin filters can effectively deal with carbon monoxide. So, if possible, it is better to avoid long-term idle in the automotive congestion, otherwise light poisoning can be considered guaranteed. One of the options to combat carbon monoxide inside the cabin is the activation of the recirculation mode that excludes the outside of the air from the outside.

Nitrogen oxides, negatively affecting the respiratory organs, also constitute a pretty share of polluted urban air. NO compounds as a result of photochemical reactions with water in the atmosphere, lead to the formation of nitric acid, which together with precipitates falls on the ground in the form of so-called acid rains. For car enthusiasts, consolation is the fact that any nitrogen oxides are successfully neutralized by cabin filters, however, only those that have activated carbon. It should be noted that the adsorption properties of coal filters in terms of capturing NO deteriorate during operation, which leads to a significant reduction in their effectiveness of their work.

Formaldehyde belonging to a series of aliphatic aldehydes is a toxic colorless gas with a sharp smell. With large dosages, it may lead to poisoning, but even in highly rolled exhaust airs, its concentration rarely exceeds the maximum permissible values. In addition, coal salon filters are very well coped with formaldehydes.

On the other harmful substances we will not stop in detail. We only note that all of them, whether aliphatic hydrocarbons (methane, ethylene and others) or ordinary soot, are well eliminated by coal salon filters.

Types of salon filters

Salon filters used in the car are divided into two most common groups:

• Ordinary anti-free filters;
• Coal filters.

Simple dust filters carry out air purification from dust and soot, as well as from pollen plants and other allergens. As a filtering element, paper or synthetic fibers are used in such filters, which are able to delay particles up to 1 micron. Materials from synthetic fibers can be electrified, so in addition to mechanical retention, the ability to capture particles by attracting. The main differences between the dust salon filters from the air filters of the engine power system is the lower density of the filter material. This is due to the fact that the ventilation system of the car is not able to create such a strong craving, which is provided by the intake manifold. The cons of dust salon filters should include their absolute helplessness in the fight against toxic gases and unpleasant odors.

Coal salon filters are capable of purifying air from any harmful compounds, experiencing certain difficulties only with carbon monoxide. As a working element of this type of filter, activated carbon is used - a porous substance having a large specific surface. It is formed due to the set of microscopic pores, the smallest of which have a size of about one nanometer. It is due to these pores that the molecules in contact with the activated carbon of toxic gases are captured, and the capture is made with large-dimensions by macro and mesopores, and then transportation to micropores. This phenomenon received the name of adsorption. To delve into the nature of the occurrence of intermolecular forces, which can be realized by others, we will not, we note only that the larger the molecule of the absorbed substance, the easier it is to capture them and hold. The efficiency of adsorption by the coal filter does not last depend on such factors as the speed of the passing flow and air temperature.

If you refer to the constructive features of cabin filters, the activated carbon used for them is a granules of about 0.5 mm, fixed on a special substrate from textile material. Most coal filters have a multi-layered structure in which the "coal" layers alternate with layers from the usual anti-fiber. Each of the interlayers is responsible for capturing the particles of a particular type and size. As a result, the air turned into a multi-stage processing enters the cabin in absolutely clean and safe for inhalation.

Where is the cabin filter and how to replace it

Despite the fact that cars of different manufacturers have essential constructive differences, they use, as a rule, salon filters of the same shape. This is usually a rectangular cassette with a characteristic corrugated filtering element and a more or less rigid frame around the perimeter, providing installation without distortion in compliance with the required edge adjustment density. The installation site of the salon filters is also not much different. Usually they are either in the open space, or under the front panel in the passenger seat zone (often behind the glove box). Answer the question where the cabin filter is located in a specific model of the machine, only the manual for its operation will be able. It describes the sequence of actions when replacing.

The procedure for replacing the salon filter depending on the car may require different labor costs. For example, the owners of Toyota Corolla to fulfill this action do not have to make a lot of effort. In this case, the air conditioning unit in which the cabin filter is inserted, is located immediately behind the glove box. The latter can be thrown away by removing the side limiter and squeezing the box itself on both sides. Access to the salon filter is obtained, so now it is enough to remove the old cassette and replace it with a new one.

On some models there are certain nuances associated with the replacement of the salon filter. For example, in some cases, it is not so easy to get to the location of the filter element, so when installing the risk there is a risk of leaping any edge of the filter or not enough to put it in the fixation unit. It is clear that the occurrence of even the minimum gap in the filtering zone will lead to a clear decrease in the efficiency of the cleaning system. Another point, no longer dependent on the car, is the need to take into account the direction of movement of air flow. Install the cabin filter will properly help the corresponding arrows applied to the side edges of the element.

The frequency of replacement of air filter salon

In the course of operation, the cabin filter is inevitably clogged, so it will be necessary to replace it sooner or later. The manual for the car indicates a specific replacement interval of the filter element, tied to the execution of planned regulations. However, it is advisable to implement this procedure on the actual state of the salon filter, as it depends on a number of factors. Obviously, the replacement will have to be produced more often if the car is operated in conditions of severe dusting or gas supply. For example, the filter will explicitly come into disrepair with regular driving on dirt roads, where the concentration in the air of various kinds of particles is significantly higher than on little loaded urban streets. Large load on the cabin filter lies in large megalopolis, literally drowning in smith from car emissions and industrial enterprises. Also for the service life of the interior air filter has an influence of the type of material from which it is manufactured. More qualitative filtering elements are capable of functioning normally and after 15-30 thousand km of run, while the fake will not even stretch the half of this period.

There are several signs speaking the need to replace the salon filter:

1. Reducing the performance of the ventilation system, i.e. The flow of air from the deflectors was less intense than before;
2. The appearance of persistent odor in the cabin, obviously not related to external sources;
3. High fogging glass.

Many car enthusiasts for savings prefer to clean the salon filters with their own hands, and then re-use them. The idea, I must say, unsuccessful, because no cleaning with reservoir means can one hundred percent restore the initial properties of materials. This is especially true for coal filters, the principle of operation of which is based on very complex internal processes occurring at the molecular level.

conclusions

Of all the above, it is possible to do an unequivocal conclusion: a cabin filter is a necessary component, the timely service of which is the key to preserving inside the car of a pleasant atmosphere, eliminating the risk of light ailments and serious diseases. When choosing the air purifier, it is worth paying attention to products of well-known brands located in a higher price category. This is exactly the case when you can overpaid and get knowively better products, many times better performing your functions and at the same time maintaining performance when mileageing up to several tens of thousands of kilometers. Choosing between dust and coal salon filters, preference should be given to the latter, because they are more efficiently opposed to toxic substances.

The cabin filter does not affect the operation of the machine - the engine valves or the brake system will not work worse due to its clogging. But it cleans the air entering the car's salon, from dust and other harmful contaminants rising from the roadway. This node is especially important if the car owner or its passengers is possible allergic reactions to any substances. It will help make the air in the car's salon clean, without dangerous impurities. However, for a better result, this element must be changed regularly.

1 Where is the cabin filter?

The element may have a different location:

• for most cars, this element is located behind the "glove" - \u200b\u200bcompartment for gloves or immediately under it or above it - those Renault (Logan, Duster, Sandero and other models);
• some machines have a special design of the dashboard, and they have a cabin filter directly under it, and deep enough;
• there are cars in which this item is placed in a special cassette and is located under the hood (bright examples - Ford Focus 1, Daewoo Nexia, as well as model VAZ-Lada Kalina, Priora, Grant).

Difficulties with self-replacement of the cabin filter may experience only the owners of the machines from which it is very deep under the instrument panel. In other cases, change it with their own hands will not be much difficulty.

But there is one general rule: the frequency of replacement of the salon filter depends on the intensity and climatic operating conditions of the machine. If the car "works" in the southern region with a high content of sand and other similar substances in the street air, its cabin filter will be contaminated much faster than in the car operated in the latitudes with cleaner air.

It affects the frequency of changing the node and the ride time ratio in the city feature and outside the city.

If a significant amount of time, the machine is operated in the city feature, it is in a dense stream of cars and the clock is in multi-kilometer traffic jams, its cabin filter will be polluted much faster than a vehicle that is more often driving around the country roads.

But regardless of the operating conditions of the machine and manufacturer's recommendations, the filter replacement must be carried out at least once a year, even if the car has a small mileage.

However, on the trick of unscrupulous masters of the workshop or car wash should not be to succumb. If, when maintaining or cleaning the machine, you are inclined to the fact that the replacement of the node is needed, first examine its appearance. Perhaps the need for his change is still missing.

The element has become unusable if its plates are very dirty, there is garbage between them - leaves, small branches, soot, soot, insects. In this case, you really need a new filter.

3 signs of the need to replace the element

There are several indirect signs for which you can independently determine the moment when it comes to changing the filter in the cabin:

• on the street, the air is clean and fresh, but in the cabin of freshness and purity is not felt, when the auto movement, the situation is deteriorating, and air conditioning or flavors do not help correct the situation;
• when you turn on the maximum power system of the salon ventilation of a strong blowing of the air is not observed, but dust appears in a noticeable amount;
• the salon has an unpleasant "dusty" smell.

Also, you need to start the alarm, if the car started overly fogging from the inside glass.

4 Types of Filters for Salon

When choosing a new element, its size and compatibility with a particular brand of machine will become the main criteria. And the type of its main working material is chosen by the car owner on the basis of personal preferences. The choice of the following types:

• The usual paper, made of porous paper and ensuring filtering exclusively at the mechanical level.
• Coal produced from paper material with special spraying capable of eliminating unpleasant flavors and absorb some toxic gases.
• The coal-polyphenol, ideal for people with manifestations of allergies on a variety of particles, filling in the air. This is also paper on which activated carbon and polyphenol composition are applied.
• Electret, very expensive, but the most effective, containing a special layer of thin fibers with an electrical charge in its design.

The cabin air filter element of any type is a disposable consumable material to be replaced with its contamination. Attempts to clean them with a vacuum cleaner or other means, not only will not remove the microparticles already deleted by the element, but will make the node even more dangerous for the driver and its passengers.

5 How to replace your own hands

This operation is quite easily and quickly performed by your own hands. It is necessary to determine the location of the filter in the car, get to it and carefully remove, trying not to damage the locking latches.

The compartment in which the item was located, you need to spend it over or clean with a wet fabric. After that, a new filter is installed.
