Which cabin filter is better - carbon or regular?

How the filter works

Air enters the car interior through air intake openings in the heating system. It can do this in two ways:

by gravity;
forced injection using a fan.

Based on its functionality, the filter is installed in the housing of the heating system. Classic filter devices are made of the thinnest paper, which is filled with electrostatic charges and impregnated with phenol-aldehyde liquid.

This technology of a filter device involves not only retaining large grainy air impurities by the device, but also attracting smaller particles, and in addition, unpleasant odors are neutralized.

Installing filters is most effective for people who suffer from respiratory diseases (asthma, allergies, etc.) who react to all kinds of odors, dust, pollen and other irritants in the inhaled air.

How the filter works

Types of cabin filters

When choosing a filter, you should first focus on its size. Depending on the car model, the sizes of cabin filters differ, and on the packaging with the consumable element, manufacturers indicate for which cars it is suitable. At the same time, cabin filters differ not only in size, but also in the materials from which they are made. Depending on the filter materials, the following types of filters can be distinguished:

Paper. The most common filter models are made of porous paper, which limits the passage of small particles while allowing air to penetrate into the cabin. Filtration occurs only at the mechanical level, and such filters are the cheapest;
Coal. Carbon filters are also made of paper, but with a special coating that can eliminate unpleasant odors coming from the air, as well as absorb harmful gases. The problem with carbon filters is that they show their benefits until the absorbent properties of the carbon are depleted, which happens faster than the recommended time for replacing the element. Accordingly, after several thousand kilometers, the properties of a carbon filter become equal to that of a conventional paper filter.
Carbon-polyphenolic. Common filters among people who have allergies to various particles that may be in the air. Such filters are partially coated with activated carbon and partially with polyphenol, which is an antioxidant and is able to fight allergens, preventing them from entering the cabin;
Electret. Expensive cabin filters that are rarely installed in cars by manufacturers. These filters differ from other options in that they contain not only a layer of sprayed paper for mechanical filtration, but also a separate layer of electrically charged fine fibers. Electric charges allow you to attract microscopic particles, preventing them from entering the cabin. Manufacturers of such filters claim that their efficiency in retaining impurities measuring tenths of a micron reaches 99%, and 30% for particles measuring hundredths of a micron.

Important: Cabin filters of any type are disposable elements that must be replaced when dirty. Cleaning the filter elements with a vacuum cleaner and other means will not remove retained microparticles and, accordingly, will not give any results.

Barrier filter

This copy is made from the finest paper or linen (natural or synthetic). Such filters are designed to retain the smallest mechanical suspensions in the air. They clean the air flow entering the cabin only from dust (sometimes from small insects).

Carbon filter device

A small layer of carbon is applied to the filter material of such a device. It helps to absorb hazardous impurities contained in the air and neutralize unpleasant odors. This filter has improved filtration qualities when compared with its barrier analogue. But it is important to know that over time the filtering properties of the key element (coal) are lost, which leads to their transformation into a regular filter.

Cabin air filter

Carbon element with special coating

In this version, an ordinary carbon filter has an additional polyphenolic antioxidant coating. Such devices neutralize allergens. In them, a layer of activated carbon is applied to one side of a porous material, and a layer of polyphenols, a natural antioxidant, is applied to the other side. This sample has a higher cost and is most in demand during periods of flowering plants and increased activity of allergens.

Electret filter element

In addition to the ordinary linen layer, such a device is equipped with an additional electrically charged layer of thin fiber. The first layer is assigned the function of mechanical filtration, while the second one is responsible for attracting microscopic particles of all kinds of air impurities. Manufacturers of such devices claim that this filter blocks:

99% of various particles ranging in size from 5 to 100 microns. Such impurities include pollen, fungal spores, dust of various origins;
over 65% of particles having a diameter from 0.3 to 1 microns (smoke/soot/bacteria);
up to 35% of microscopic particles having dimensions equal to a hundredth of a micron.

Combination filter

This device combines carbon elements and electret layers. The device has several degrees of cleaning. In addition, multilayer filter devices are commercially available. They have a mechanical cleaning layer combined with an electrostatic, antiseptic and carbon layer.

Barrier and carbon filter devices are most in demand among Russian motorists, since they have the lowest price. Filters with anti-allergenic characteristics are premium class devices.

Cabin filter function

When installing a cabin filter device, it is important to know that any filter, regardless of the type and cost of the device, is a disposable element that must be replaced after a certain period of time.

Is it possible to drive without an air filter at all?

The question of whether it is possible to operate a vehicle without a filter is often asked by owners of domestic cars. This issue is especially active on the Daewoo and Ravon forums, where the interior ventilation system is designed very wisely, but not very effectively. To change the filter in these cars, you will have to dodge for several hours if you have no experience. And the cleaner itself often becomes the cause of problems. It is not recommended to drive without a filter for the following reasons:

Unpurified air enters the cabin, and various solid particles, leaves, dust and other undesirable environmental elements reach the fan and radiator;
Air ducts, which are designed to blow glass and warm up the air in the cabin in winter, break down much faster and have to be cleaned and repaired;
fogging of windows becomes a normal phenomenon at the first temperature change, no blowing helps to cope, and sometimes aggravates the problem;
the efficiency of the stove in the winter cold decreases, the air intake nozzle from the street easily becomes clogged, which is also fraught with its own troubles during operation;
on budget cars, the housing of the filter device may become deformed, which in the future will not allow the normal installation of a new filter without any special problems and difficulties.

These are the kind of troubles that can happen to those car owners who decide not to install an air purifier in the cabin. On expensive foreign cars, you shouldn’t think about such an idea at all, as this can lead to breakdown of the climate control system, clogged air ducts and very expensive repairs in the future. So you should be more careful in taking into account advice on various forums from unverified experts.

How to understand when it's time to change the filter

Manufacturers recommend changing the cabin filter at least every 12-15 thousand km or once a year. If you drive your vehicle in a dry climate with moderate levels of dust in the air, the replacement intervals may be slightly longer. If you do not know the installation date, the following symptoms may indicate a replacement:

air flow has decreased. To ensure air circulation, you have to increase the speed of the stove motor. In summer, less fresh air will enter a car with a clogged filter, and in winter, the interior will warm up much more slowly;
An unpleasant odor appeared in the cabin, which intensified when the air conditioning system was turned on. If replacing the cabin filter does not produce results, you will have to clean the entire system;
glass fogging. A similar effect occurs due to the absorption of moist air, which becomes so after passing through a wet filter. If you have noticed a similar effect, check out the entire list of reasons that cause glass fogging in the cabin.

You can always pull out the filter and assess the condition of the filter element.

Replacement timing

Each manufacturer recommends replacing the cabin filter at different intervals. If we calculate the average number, we get 15-20 thousand mileage before replacement. Usually it is worth focusing on operating conditions. In the southern regions, where there is a lot of sand and dust, the filter will have to be changed twice as often as in regions with a temperate climate. Naturally, in polluted large cities the filter will not last as long. In any case, replacement is recommended at least once a year.

If you notice a decrease in air flow into the cabin from the ventilation system, this clearly indicates that it is time to change the cabin filter.

Which filters should you change when changing engine oil?

For normal and stable functioning of the engine and the car as a whole, filters need to be changed regularly. After all, even the highest quality fuel still contains some impurities that need to be kept from penetrating into the combustion chamber. It is also important that the air enters the engine without various impurities, so as not to complicate the operation of the engine. Therefore, many motorists have a question about which filters to change when changing the engine oil.

Most experts say that when changing lubricant, it is better to change all filters. This will allow you to clearly know at what specific mileage all filter elements were changed.

It is advisable to systematically monitor the performance of automobile cleaning elements. Untimely replacement of these elements can lead to contamination of the engine with foreign particles, which will ultimately cause engine failure or disruption of the normal functioning of its maintenance systems. Therefore, you need to clearly understand which filters to change when changing the engine oil.

Good to know: Which motor oil is not counterfeited in Russia, list of the best

Basic technological requirements for manufactured filters

Due to the significant dependence of the normal operation of the engine on its performance, the following requirements are presented to them:

optimal parameters;
high-quality and durable material;
convenient location in the car body for quick and convenient replacement;
maintaining an optimal level of performance under various weather and climatic conditions;
performance under increased technical loads.

Why is a filter installed in a car?

Modern cars have five filters: particulate filter, cabin filter, fuel filter, air filter and oil filter. They all perform certain functions:

ensuring normal engine operation in critical modes;
starting the engine at low temperatures;
reducing the flow rate of lubricant and air;
isolation and disposal of harmful foreign elements.

Oil filter operating mechanism

It controls the volume of lubricant supplied to the engine, while simultaneously cleaning the incoming substance from all existing coarse impurities. The filter housing contains high-strength porous paper. The surface of the paper is treated with a special waterproof resin.

It must be replaced simultaneously with the replacement of the lubricant. Basically, such a replacement is carried out after 12-15 thousand km. mileage This figure is an average, and the exact replacement parameters should be obtained from the car’s developers and manufacturers. The simple design provoked such a situation in the automotive spare parts market that many companies began to produce this filter element.

But for the correct purchase and reliable and long-term operation, you need to buy the original product and exclusively by the catalog number. This is the only way to avoid purchasing a fake and causing subsequent problems with the operation of the car. Installing a poor quality one can lead to rupture of the filter material or housing, which will cause lubricant to leak from the engine.

Purpose and mechanism of operation of the air filter

It functions to purify atmospheric air coming from the environment, which enters the power unit through air ducts. This element itself is made of porous and thick paper fixed in a plastic case.

It needs to be replaced at the same time as the oil change, but if the car travels most of its mileage on dusty dirt roads, then it should be replaced earlier.

You can replace the filter yourself, since it is located in a fairly accessible place and even a novice motorist can do this work.

Functions and principle of operation of the cabin filter

It is designed to purify the air that enters the car interior. The filter is assembled from a housing and activated carbon located in it, through which the air flow passes, and foreign particles remain in it. As various debris accumulates, it loses its functions and needs to be replaced.

You also need to remember that this filter protects the air conditioner evaporator from clogging. It is recommended to replace the filter simultaneously with updating the oil. But if the windows fog up in humid weather, then this is the main sign that this filter needs to be replaced.[/stextbox

Fuel filter characteristics

It is used to clean the fuel entering the power unit. The purity of the fuel used directly depends on the duration of normal operation. There are two types of fuel filters installed in cars: in-line and submersible.

They must be replaced according to the recommendations of the car manufacturer or the first signs of failure. If you do not change it, this can lead to the following consequences:

clogging and subsequent decrease in the efficiency of the fuel system;
breakdown of injectors;
reduction in engine power;
unstable operation of the unit as a whole.

Working principle of the diesel particulate filter

They are installed exclusively on vehicles equipped with diesel units for collecting soot and various solid particles. They are replaced only in exceptional cases, since they are capable of performing their functions throughout the entire life of the engine. You can clean the filters yourself using a post-injection process.

Good to know: Do I need to fill the filter with oil when changing the oil?

Conclusion

Car filters require constant care and, if necessary, replacement. The answer to the question of which filters to change when changing the engine oil remains open while there are several points of view on this topic.

To know how long each filter has worked, it is advisable to change them at the same time as changing the oil. You can follow the recommendations of various companies and change them at different times or due to their failure. The choice always remains with the motorist.

Where is the cabin filter located?

Car manufacturers can install the cabin filter in various places in the cabin, but they try to take into account the fact that the filter element has to be changed quite often, and accordingly, access to it should be easy. Only the operating book for a specific car model, in which this information should be displayed, can clearly say where the cabin filter is located.

Most often, the cabin filter is installed behind the glove compartment or under it. You can find cars in which the filtration element entering the cabin is installed on the driver's side, for example, under the dashboard. Some car manufacturers install a filter at the air inlet, that is, they place it under the hood in a special housing or recess, in which case it is easiest to replace.

Filter element installation location

Despite the differences in the designs of filters of different types and different manufacturers, in appearance the filtering devices are often not very different from each other. Although the installation location of the filter element varies in cars of different brands. The most common options are:

under the main panel, behind the glove compartment, opposite the passenger seat;
in the space under the hood of the car on the driver's side;
directly next to the steering column, above the pedals.

Depending on the location of the filter device (this is influenced by the vehicle model), the procedure for replacing it differs. Therefore, when it needs to be replaced, it is better to seek the services of a car service center. Otherwise, there are certain risks of deforming the edge or frame of the filter device, not fitting the device tightly enough into the socket, or damaging the seat of the filter element.

Filter location

When to change the filter

During operation and constant work, debris accumulates in the corrugated element of the filter, this leads to its incorrect operation and requires replacement of this device. The timing of filter replacement is indicated in the vehicle operational documentation and, as a rule, coincides with the scheduled maintenance period.

Note that sometimes replacing the air filter is required much more often. This is acceptable when the vehicle is used in conditions of excessive gas/dust pollution. Reducing the operating period of the filter element is recommended when:

continuous movement by car on a dirt road;
constant trips during the flowering period of plants, which shed a lot of petals and fluff;
traveling in big cities where traffic congestion is common.

In addition, the quality of the device itself also influences the frequency of replacement. While a high-quality filter element from a trusted manufacturer will last 15-30 thousand km, a counterfeit device may not last even 50% of the period stated in the regulations.

Replacing the filter
The fact that it is time to change the filter device can be determined by some indirect signs:

The air supplied to the cabin has an unpleasant odor.
When the fan is turned on, dust appears.
The strength of the air flow during blowing has decreased, the air conditioner/stove works worse.
The windows in the car began to fog up heavily due to the high humidity.

Failure to replace the filter device on time leads to the accumulation of dirt, which favors the development of fungus, mold and bacteria, which intensively spread through the system ventilation channels. Under such conditions, the device turns from an air purifying element into a source of spread of various diseases. You also need to understand that vacuuming, washing or washing does not restore the properties of the filter materials.

Is it possible not to change filters in a car?

The operation of a car involves various mechanisms that require filters to function correctly. They are necessary in fuel supply systems, air, climate control, and lubrication systems. How often to change filters in a car, because by retaining excess working mixtures and waste materials, they become dirty. Let's talk about this today.

How often to change the oil filter in a car

To understand how often to change the oil filter in a car, you need to pay attention to the following:

Engine Features
. Everything matters: what fuel it runs on, what the compression is, engine operating temperature, pressure, friction force of parts - these indicators significantly affect oil contamination. Therefore, in different engines, oil filters are stressed according to their characteristics. Powerful engine? This means you need to change the oil filter often.
Filter element
.
It uses a special porous material similar to paper. It is laid in an accordion to increase the filtration area. The better the filter element and the larger its area, the longer the filter will be able to perform its function. As soon as it is completely dirty, the bypass valve will start working, which means it’s time to change the filter. How often this should be done depends on the rate of contamination.
terms of Use
. One of the most important criteria that determines how often the filter needs to be changed. The change time depends on the mileage of the car, but it is necessary to note the fact that with the same mileage for cars with different purposes, filter wear can vary significantly.
Thus, the oil filter of a city car will be much more loaded than that of a car that travels mainly on highways, which means that it may need to be replaced often.

According to the rules, you need to change the filter as often as you change the oil in a car engine. Each brand of car has its own oil service life, but usually it is within 10,000-15,000 km.

But there are times when it is necessary to change the oil filter ahead of time:

After a major overhaul of a car engine, when the cylinder head (cylinder head) or sump is opened, the filter is changed along with the oil, regardless of whether they have expired or not.
When the engine lubrication system is washed with a special compound, a temporary filter is installed, preferably a cheap one, since it cannot be used after the procedure is completed. After washing, they install a good quality part for regular work until the next shift.
Happy owners of cars with powerful engines practice changing the filter ahead of time in order to avoid breakdowns. After all, it’s better to play it safe and spend extra money on a new filter and oil than to pay a considerable amount for repairing an engine with the latest technology.
If the car has been sitting for a long time. Even if fresh oil was poured into it before downtime, it has an expiration date and loses its lubricating properties, and also releases oxidation products that impregnate the filter materials. Therefore, if you decide to drive a car that has previously been parked for at least a couple of years, be sure to fill the engine with fresh oil and install a new filter.

When to change the air filter in a car

The principle of operation of an internal combustion engine is known to all motorists, but let us remind you that its essence lies in the interaction of the air supply with the fuel supply. And how well and in the correct volume fuel will flow into the combustion chamber depends on how much air enters the system. The filter in the air system cleans the air of impurities, and when it is dirty, it becomes an obstacle to the supply of the required volume.

The air filter is changed as often as a scheduled inspection; manufacturers advise doing this every 15,000-30,000 km. But you should still carefully monitor the degree of contamination of the element and change it in accordance with it, otherwise the engine may malfunction. Particular attention should be paid to the air filter if you had to visit dusty (rural or dirt) roads. In such conditions, its contamination occurs instantly.

Moreover, it is very easy to check the condition of the filter. It is located in a special box directly under the hood, which can be opened with a regular screwdriver. All you need to do is assess the condition of the filter. If it is clean, put it back and continue using it. If dirty, replace it. The air filter can be changed as often as you like.

How often to change a car's cabin filter

A modern car is a rather complex mechanism consisting of the interaction of many systems. Some parts can last quite a long time, and there are some that require replacement quite often. Cleaning elements are those that must be changed more often than others in order to maintain the correct operation of the entire car. A filter for cleaning the air in the cabin is of no small importance.

It turns out that some car owners do not think about changing the cabin filter and use it for years. Craftsmen and manufacturers advise carefully monitoring its contamination and changing it approximately every 20,000-25,000 km. After all, the cleanliness of the air in the cabin depends on this. In addition, modern cars are also equipped with carbon filter elements, which not only clean the air of dust, but also eliminate unpleasant odors.

It is also necessary to pay attention to the environment. If it is exposed to gas pollution (metropolis) or too dusty (steppes), then you may have to change the cabin filter more often. Tips on this issue can also be found in the operating instructions for your car. It’s better, of course, to pay attention to the rate of contamination of the part and then rely on the experience gained, since each case is unique and depends directly on the operating conditions of the car.

Do not underestimate the importance of the cabin filter. Its unsuitability can lead to bad consequences. Firstly, the entire air system may deteriorate. Secondly, freezing of the evaporator radiator occurs.

Thirdly, all this may create an unpleasant odor in the cabin, which will not be so easy to get rid of. In cars equipped with climate control, the entire operation of the system depends on the filter.

If it fails to clean the air, there is a risk of serious damage.

How often should you change the fuel filter?

The fuel filter performs one of the most important functions in the operation of a car engine, namely, cleaning the fuel from debris, excess particles, debris, and dust so that they do not get into the cylinders and interfere with their operation. In modern internal combustion engines, fuel purification occurs in two stages: through a coarse filter and a fine filter.

The first is a nylon net stretched directly in front of the gas pump; it sifts out large debris - debris, shavings, sawdust from friction of parts, etc. The fine filter is somewhat more complex and comes in two types: remote and built-in.

The remote is located outside the fuel tank, usually under the hood or underbody of the vehicle. Only remote filters are installed in diesel engines, because they additionally include water sensors and a drain plug, and sometimes heating.

Built-in filters are part of the fuel pump and are more relevant on modern cars. Manufacturers are abandoning remote filters due to their outdated design, and only some brands, such as Volkswagen and AVTOVAZ, continue to use them.

Manufacturers regulate different service life of different types of filters. It is recommended to change the remote ones not so often - approximately every 30,000-40,000 km. Built-in ones are even rarer - about 100,000 km! It's better not to change at all.

This is because replacing them will entail dismantling the fuel pump, which in turn can lead to disassembling the fuel tank, and this is hard and highly paid work.

So it is advised to finish the built-in filters to the end; fortunately, they are made with high quality and for a long time.

The remote filter must be changed with care. Due to its location, there is a risk of clogging the fuel injector nozzles through the supply hoses.

Changing fuel filters too often without following the manufacturers' instructions is completely pointless. But, if dangerous signals appear in the operation of the engine - consumption has increased, traction has disappeared, the engine is acting up - the first thing you need to do is check them.

Is it possible not to change some car filters?

During scheduled maintenance, technicians first advise changing all the filters in the car. This, in principle, complies with the manufacturers' regulations, but does not mean that you have to agree with it. Some filters do not need to be changed so often, but rather cleaned. Auto mechanics will help you with this. But this procedure is not suitable for all filters. To find out which ones, read on.

You definitely don't need to change the air filter that often. In winter, it is practically not polluted. And in the summer you can clean it yourself - using a cloth, a vacuum cleaner or a compressor. The main thing is to do this often so that it does not have time to become completely unusable. This way, its service life will increase significantly, and you will save money.

Still, you should listen to the recommendations of the manufacturers and not be too self-willed, because they will not give bad advice - only what will help the car function properly for as long as possible. And cleaning the air filter yourself can be useful as a last resort in an emergency.

The same recommendation applies to cleaning the cabin filter, because they also should not be changed too often. The manufacturer recommends doing this every 10-15 thousand km, in reality - not so often, you don’t need to worry earlier than after 20-30 thousand km. Again, we focus on our experience and take a closer look at the environment in which the car has to operate.

After the peat bogs burned in Moscow (everyone remembers that smog), absolutely all car owners were required to replace cabin filters, regardless of how often they were used to doing it. This is because even after a couple of thousand kilometers, the parts became shamelessly clogged with fumes, and it leaked into the cabin, threatening people’s health. Therefore, everything is individual and all factors must be taken into account.

In any case, timely cleaning of the cabin filter will help you save money on replacing it and protect you from malfunctions.

But it is worth noting that the service life of cabin filters is quite long, and even without cleaning they work properly for about a year. Most likely, after such a marathon, cleaning will no longer help, and you will have to change it.

But fuel filters cannot be cleaned - only changed. The good news is that you don’t have to do this so often. Oil ones too, but they have to be changed quite often - every 10-15 thousand km, depending on the manufacturer’s recommendations, along with the engine oil.

The car requires attention and care to maintain its performance. Frequently changing consumables and parts is the best way to achieve this. Follow the advice of manufacturers and experienced car owners, and your car will last you longer.

Preparation for replacement and necessary tools

The period during which you can complete the procedure for replacing an air purification device is 15-20 minutes. The procedure is carried out by the driver independently. The tools you need to have are a set of wrenches and screwdrivers and a clip remover or pliers. It is advisable to carry out the procedure in overalls and have a flashlight and gloves with you.

First you need to drive the car onto a pit or overpass. An example of the procedure for installing a filter unit can be given on a Lada Kalina car.

The procedure for replacing the cabin filter in Kalina is carried out according to the following principle:

turn on the wipers and turn off the ignition when the wipers are positioned at the top;
determine the right side of the frill and find the filter. Remove the frill grille and remove the element cover;
to remove it, you must follow the rules: pull the body to the right, lift the left side of the cover and pull it in the opposite direction;
bend the lock and remove the product;
Install the new filter with the side marked with the arrow pointing air upward.

The procedure is completed by assembling the parts in the reverse order.

How to change the cabin filter device

In fact, this element can be changed quite simply; you just need to correctly determine its location and then get close to it. It is extremely important, when removing the plastic inserts behind which the filter is located, not to damage the snap elements that secure them. It is advisable to read the car’s instructions several times, which detail how to remove the mount, how to restore it, or completely replace the element due to a breakdown.

After dismantling the used filter, do not rush to install a new element in its place. Experts advise using a vacuum cleaner or otherwise cleaning the area where the filter device was located. After this, you can begin installing a new filter. At the same time, do not forget to look at the indicators on the device - they will indicate which side to install the filter device correctly.

Old and new filters

Some companies provide installation diagrams for the filter device. Usually, this is an arrow that indicates the direction of air flow: when the pointer is pointing down, it means the air flow is coming from above.

If there are no indicators, you should determine on which side the grooves are deeper. It is through this side that the air passes before it is cleaned. The logic is that grooves with greater depth require a longer collection of large debris and leaves. Let's look at how the filter device changes on some car models.

Changing the filter on Toyota

In the Corolla model, the cabin air filter is located at the passenger's feet behind the glove box. To change the filter, you don't need anything, just a new device.

This is interesting: Instructions for replacing the fuel pump yourself

There are special latches on both sides of the glove compartment. When they are unfastened, the drawer lowers slightly. This will give access to the filter unit. The block is held in place by 2 latches that must be released. Now nothing will prevent the installation of a new filter device.

If during installation the drawer dropped lower, you should check the micro-lift drive (small piston), which ensures smooth opening of the drawer. Most likely, it simply flew out of the mount.

How to change the filter

The sequence of actions when replacing the filter device is as follows:

From the sides, inside the glove box, you need to remove 2 snap-on stops, moving them slightly and then pulling them towards you.
Unfasten the travel stop from the right edge.
When the glove compartment is lowered, the plastic cover of the filter device will become visible. The element can be changed by removing the cover, which is held in place by three snap elements.

Changing the filter on Daewoo

In the Lanos model, the internal filter is installed in the space under the hood. The steps to replace the filter element are performed in the following sequence:

Remove the rubber hood seal.
We unscrew the three fasteners on the left side of the “jabot” - the plastic part in which the wipers are attached. Then you need to slightly pull it towards the near wing and remove it.
Reach through the opening to find the top of the filter device. The new cabin filter is placed in the same place.

Note that when replacing the filter element on Lanos, you will need to show some resourcefulness.

How often to change the air filter in a car - Useful information

The air filter is a part without which the normal functioning of the engine is impossible. Due to the peculiarities of its operation, which we will discuss later, it often becomes clogged, which means it requires regular replacement.

Otherwise, you risk paying much more to repair the entire internal combustion engine. In this article we will talk about why it is necessary to change the engine air filter, how often it should be done, and also give some useful tips.

This information will help not only beginners, but also experienced car owners.

How does an air filter work and why does it need to be replaced regularly?

Everyone probably knows that in order for anything to burn, oxygen must be supplied. For example, you can put out a candle by covering it with a jar. The same thing happens in the engine. The fuel-air mixture burns in it, and the engine is designed in such a way as to ensure the required ratio of fuel and oxygen. This process occurs in any engine, regardless of its type, with some features:

In atmospheric engines, air enters through rarefaction, that is, it is simply sucked inside.
In compression and turbocharged engines, air is supplied forcefully, that is, under pressure. As a result, more fuel enters the engine, which ultimately allows you to burn more fuel. This, in turn, leads to an increase in engine power without the need to change the displacement and number of cylinders.

What function does the filter perform in this process? Air enters the engine from the outside, which means that particles of dust, dirt, moisture and other substances that do not belong in the engine can get there with it. The filter's job is to prevent this from happening. It purifies the air, removing all of the mentioned pollutants from it, without reducing the incoming volume and speed of entry into the engine. As a result, the required fuel combustion rate and protection of engine elements are ensured.

If the filter is not replaced on time, you may face a number of negative consequences:

The volume of air entering the engine will decrease. As a result, there will not be enough of it to burn fuel efficiently. In carburetor cars, this will lead to a sharp increase in fuel consumption. In more modern cars equipped with a lambda probe and an air flow sensor, this will not happen, since the automation will adjust the amount of fuel supplied, but this will reduce engine power. In addition to this, you may experience problems starting the engine, slow acceleration or jerking.
The risk of filter breakout increases. This is a fairly rare phenomenon, which most often occurs due to improper installation or poor quality of the part itself. If a breakthrough occurs, abrasive elements may enter the engine, which will greatly undermine its service life.
The wear of engine parts accelerates. The first to suffer are spark plugs, catalysts, and particulate filters. This is due to deposits that begin to form due to incomplete combustion of fuel. If they are not promptly removed, the harm to the engine can be very serious: the catalyst, for example, can melt.
Other negative consequences are also possible, for example, flooding of spark plugs, mixing of unburned fuel with engine oil, and breakdown of the oxygen sensor. The cost of all the listed parts is significantly higher than that of an air filter, and if you add to this the cost of repair services, the difference will be even more obvious.

To avoid negative consequences, you need to perform car maintenance in a timely manner. The air filter must be replaced during scheduled maintenance. If you trust the care of your car to professionals, then there should be no problems, but we still recommend periodically checking the condition of the part.

Not all drivers, however, take the time to travel to certified centers and prefer to service their car themselves. They regularly change the oil and the main elements of the engine, often forgetting about the less important parts, in their opinion. The air filter often falls into the latter category.

In addition, they often make two serious mistakes:

The decision to replace is made based solely on the results of a visual inspection.

Important!

At the same time, they forget that the absence of external defects in a part does not mean that it is fully operational.

They do not replace engine components on time, believing that their service life is longer than specified by the manufacturer.

They are wrong neither in the first nor in the second case.

When is it necessary to replace the air filter?

First of all, you need to have an idea of what this part looks like and where it is located. The air filter is a replaceable cartridge in which an “accordion” made of a special synthetic material traps all particles larger than 5 microns. There are seals along the edges that prevent contaminants from entering the motor bypassing the part.

The shape and type of filter can vary greatly. They can be:

Cylindrical.
Panel.
Frameless.

Manufacturers' requirements for replacing parts are usually the same: they recommend installing a new filter at every vehicle maintenance, that is, after approximately 15–30 thousand kilometers.

Important!

It is worth understanding that the service life of a part directly depends on the conditions in which the car is operated. If you live or often visit regions with dirty, dusty air, you will have to change filters more often

In this case, you will have to focus on their external condition. The same can be advised to people who service their cars themselves.

To check the air filter yourself, you must first remove it. This can be done by anyone without special skills. The filter is located under the hood, in a special plastic box. It is closed with a lid that is secured with latches or screws. In the first case, you can open it without tools, in the second you will have to use a screwdriver.

After this, you need to remove the filter and evaluate its condition “by eye”. For convenience, manufacturers always make synthetic elements that trap dust bright: yellow, white, and so on. This makes it easy to distinguish any contamination. If the filter is clean, you can safely put it back in and continue using it.

If you notice traces of dust, dirt, motor oil and other substances, especially in large quantities, then you should think about replacing it. Additionally, it is recommended to check the transparency of the part by holding it up to a light source.

If you decide to replace, then you should remove the old part, install a new one in its place and securely fix it. Pay special attention to ensure that there are no gaps between the walls of the box and the filter seals, otherwise dust will enter the engine bypassing the filter. After you have installed the new cartridge, close the cover and secure it. This completes the process of replacing the air filter.

Useful tips

In the last part of the article, we would like to look at some questions and errors that car enthusiasts encounter. Let's get straight to the most important tip.

Important!

Driving without an air filter is prohibited. If you decide to replace a part, do not try to remove it and go get a new one.

The absence of a filter will result in unfiltered air entering the engine, and with it various pollutants. This will lead to disruptions in the operation of the motor, and in some cases may lead to serious damage.

The first blow will be taken by the throttle system, as well as the flow meter and various sensors. Scores can form in the cylinders, which will significantly undermine the engine's service life. For these reasons, driving without a filter is prohibited. Even if the part is clogged, it will provide some protection. However, we recommend not using the engine at full power to avoid incomplete combustion of fuel.

The second piece of advice we would like to give is intended specifically for those who love excessive savings.

Important!

Trying to blow or wash the filter yourself is not an alternative to replacing it.

This money-saving approach may improve the appearance of the part, but will not change the fact that it is clogged. Cleaning will not remove small contaminants that remain between the fibers of the synthetic filter, and water can have the opposite effect than expected: the dirt can become wet and block the air flow. Another important point:

Important!

On the roads of Russia and the CIS countries, the level of dust is quite high, so it is recommended to change the filter more often than car manufacturers require.

For example, even if the car’s instructions indicate that a new part can be installed after 20–30 thousand kilometers, it is better to do this every 10–15 thousand. At the same time, do not forget that the condition of the filter should be checked regularly. This will help you avoid unnecessary expenses. Last tip:

Important!

If your car has a turbocharged engine, then you need to pay more attention to the condition of the filter element, that is, check it more often and change it as necessary.

To summarize the article, let us once again summarize the above.

The air filter should be changed:

no less often than indicated by the car manufacturer;
more often than the established deadlines, if the conditions of its operation require it.

Remember that the price of the part is incomparable with the cost of restoring the car’s engine after breakdowns that may arise as a result of your inaction.

Subtleties of filter replacement

Now I’ll tell you where the cabin filter is located on the Lada Kalina, Ford Focus 2, Nissan Qashqai, Chevrolet Lacetti, Lada Priora 1, Priora 2, VAZ 2110-2111-2112, Hyundai Solaris:

Lada Kalina. In this car, the cabin filter is located under the hood. To replace, remove the glass facing part and use a slotted screwdriver to remove the plug. Use a regular screwdriver to unscrew the cover screws. Press on the edges of the filter frame and remove it.
Ford Focus 2. In this car, it is recommended to change the filter every 25,000 km. The filter is located in the cabin, under the steering wheel, in a special niche. You will need a 7 mm wrench to remove 3 bolts from the accelerator (gas) pedal. Next, use the same key to unscrew the screws securing the filter cover. We remove the old one and install the new one.
Nissan Qashqai. The filter in this car is located in the cabin under the driver's feet. To replace, you need to remove the cover under your feet. To do this you need a wrench with heads. After unscrewing the bolts, move the cover to the side and open it. To dismantle the damper, you need to turn on the air conditioner at maximum power. The barrier will fall out on its own. Next, disconnect the fastenings of the car’s air system control unit. Behind this mount you will see a filter. When installing a new filter, it must be bent like an accordion and inserted into its place.
Chevrolet Lachetti. In this car, the filter is located in the cabin behind the glove compartment, or rather behind its lid. We usually remove the cover with a screwdriver. Attaches with 5 self-tapping screws. After removing the screws, you need to pull the cover towards you. Remove the filter and install a new one.
Lada Priora On this Russian car, it is recommended to change the filter every 15 thousand kilometers. The filter is located under the hood. Unscrew the sound insulation between the passenger compartment and the engine, the filter will be visible behind it.
Vaz 2112. In this car, the filter is protected by the windshield. First of all, unscrew the bolts from the outside of the hood using a spanner or a socket. Then unscrew the screws with a regular screwdriver. You can remove the glass washer fluid reservoir and unscrew the 4 screws on the cap. The filter is already visible behind the soundproofing sheet.
Hyundai Solaris. This car, which is called both Hyundai and Hyundai. It is recommended to change the filter every 15 thousand km. Located in the salon. In many Korean cars, it is convenient to remove the cabin filter. We unscrew the glove compartment valves with our hands, squeeze it from the sides and remove it from the mounts. After the glove compartment is removed, you will see this same filter.

Is it possible to restore

A popular question on car forums is whether cabin filters can be restored and cleaned? Some car owners try to vacuum them or even wash them. These actions are ineffective, since it will not be possible to remove at least 50% of all contaminants. Small particles sit tightly in the pores of the fiber, so even a cleaned filter cannot compare with a completely new model. Remember that the carbon layer cannot be restored, therefore, after the expiration of its service life, models with a carbon layer completely lose their absorbent properties and are equivalent to paper ones. Likewise, blowing will not help, even when using a special installation.
