Replacing the cabin filter of Lada 2109 (VAZ 2109) with your own hands

Each component in a car plays an important role, including the cabin filter, which is responsible for the cleanliness of the air inside the car. The performance of this element is important primarily for the health of the driver and his passengers, and also generally affects traffic safety.

How to properly replace the air filter in a VAZ-2109.

How to become the owner of an adapter

The adapter allows you to seriously improve the ventilation system, so for many owners of this hatchback the question of how to become its owner is quite relevant. Let's look at all the available options:

The good thing about buying a ready-made device on the Internet is that you get a high-quality product. This adapter is made from fairly thick metal and is powder coated. The disadvantage of this method is the high cost (delivery costs can also be considerable);
ordering from local craftsmen will cost you much less, but the guarantee here will not be as good, and the quality will be clearly lower;
You can make the adapter yourself - in this case you will only have to spend money on consumables, but the manufacturing itself will take a lot of time and effort. The quality of the product will depend only on you, on your skills and the availability of the appropriate tools.

Replacing the VAZ-2109 cabin filter - it's time to breathe fresh air

How to properly replace the air filter in a VAZ-2109.

Peculiarities

The cabin filter cleans the air entering the car from dirt, dust, and unpleasant odors. All modern technical equipment are equipped with it. But VAZ 2109 cars from the factory are deprived of such a “cleaner”.

The air in these vehicles enters the heater fan through the air intake box. It is for this reason that the heater often does not work due to contamination with all kinds of debris, of which there is more than enough on the road.

The smallest particles enter the car interior, forcing the driver and passengers to breathe dust.

Way to solve the problem

Of course, you can’t drive such a car for a long time, especially with the windows closed, as you can get pneumonia or other respiratory diseases.

Nevertheless, resourceful developers still found a way out of such an unpleasant situation by inventing a cabin filter adapter, which is a grille on which filter elements are attached.

The unit is installed on the fan casing in the place where the air intake occurs.

Advantages and disadvantages of the adapter

Since the factory did not initially intend to use such a component, it is therefore not at all surprising that after installing the adapter, the level of air entering the car interior will decrease significantly.

The advantages include effective resistance to dirt and dust, as well as protection from dust accumulation on the upholstery, panels, and windows of the car.

The main advantage of this filter material lies in the ability to ensure clean air in the cabin, allowing the driver and passengers to breathe deeply.

When replacement is necessary

Signs for replacement are as follows:

Reduced air flow - naturally detected - makes it more difficult to breathe in the cabin. Also, in the winter season, the stove does not work well, and in the summer it does not cool, and the front window quickly fogs up.
Color - the stronger the contamination, the darker the color of the VAZ 2109 cabin filter.
Service life - when it comes to an end, all the above symptoms appear.

How to make a filter yourself

When removing the old adapter, remove the already contaminated padding polyester from it (it is best to use a utility knife to perform this operation). Afterwards, get a new piece of padding polyester of the same size and glue it to the frame. Ready!

How to change the cabin filter

Naturally, it is better if repair work is carried out by professionals. However, replacing the cabin filter is a very simple task that even an amateur can handle. So, in order to replace this automotive component in a VAZ 2109 with your own hands, you need to work according to the following rules and with the following tools:

Tool set

Prepare the following equipment:

New (store-bought) or your own (made with your own hands) filter;
Rags (must be clean);
Phillips screwdriver;
Sealed glue.

What to do

Having opened the hood of the car, find the installation location of this filter element;
Found the mounting location for this filter element, remove the rubber seal with all fasteners;
Unscrew the screws that secure the casing;
Remove the plastic plugs at the fixation points;
Remove the casing of the heating system, and then remove the mesh located inside.
The filter is accessible - remove it and replace it with a new one.

Installation should be done in the opposite order to disassembly.

We hope that this article was useful to you and provided answers to all your questions. After reading it, now you will be able to not only change the filter yourself, but also make it yourself! Good luck!

When replacement is necessary

Signs for replacement are as follows:

Reduced air flow - naturally detected - makes it more difficult to breathe in the cabin. Also, in the winter season, the stove does not work well, and in the summer it does not cool, and the front window quickly fogs up.
Color - the stronger the contamination, the darker the color of the VAZ 2109 cabin filter.
Service life - when it comes to an end, all the above symptoms appear.

Signs for replacement

If the filter becomes dirty or clogged, it will no longer be able to protect against dust, dirt, and unpleasant odors inside the car. Plus, a worn filter element negatively affects the heater fan motor; it wears out faster.

All this indicates the need for timely replacement of the device. If this is not done, you risk developing an allergy, as well as soon spending money on repairing other components that directly depend on the condition of the cabin filter.

Symptoms of a problem	Peculiarities
Reduced air flow	This can be discovered in practice. If the air flow has become noticeably less, this will cause poor cooling in the summer and ineffective heating in the winter. Most often, the windshield begins to fog up in winter.
Color	Some filters have snow-white filter elements, so from the outside it is not difficult to determine that the device is dirty and needs to be replaced. But most modern products are impregnated with activated carbon, which is why they are characterized by a gray color. Therefore, focusing solely on the color of the filter elements is not always relevant.
Lifetime	The filter does not have a specific resource as such. It all depends on the operating conditions and the characteristics of the roads you travel on. But in practice, it is recommended to change the device as it becomes dirty or at least 2-3 times a year

If, after replacing the filter, unpleasant odors still continue to appear inside the cabin, you can use chemical compounds that are poured into the system and forcefully remove dirt. If this does not help, you will have to completely disassemble the system, manually clean it and put it back together.

How to change it yourself?

If the cleaning device cannot effectively filter the air flow entering the interior of a car with an injector engine, it is necessary to change the device. You can replace the filter yourself or with the help of specialists. Since this procedure is simple, below we will tell you how to do it yourself.

User Alexey Romanov provided a video that shows the process of dismantling the filter device on the Four.

Tools and materials

What to prepare:

new cleaning device;
a Phillips head screwdriver;
clean rags;
sealed glue.

Algorithm of actions

How to remove and install a new filter:

Stop the engine and open the hood of the car. Find the installation location of the filter device. Remove the rubber seal along with the fasteners.
Using a Phillips-head screwdriver, unscrew the screws securing the casing located in the area of the center of the windshield. Self-tapping screws are secured with nuts.
Remove the plastic plugs from the seats.
Remove the plastic casing of the heating system. Remove the mesh located inside. This will give you access to the cleaning element. Remove it and install a new filter. To install the device, first the product itself is mounted, after which the frill is installed and the filter element is pressed against it. Before installation, lubricate the joints of the casing with the vehicle body, use sealant for this. This will allow the frill to fit most tightly to the filter.
Screw the screws back in. The procedure for replacing and installing a new filter is completed.

Nuances of choosing a filter for the cabin of the VAZ-2112

The main criterion when choosing a cabin filter VAZ-21124 and other modifications of this family is the exact match of geometric dimensions. Let us remind you that old-style filters are placed vertically and have large dimensions - 230.0x193.0 mm. with a thickness of 45 mm. The filter element, installed since 2003, is much more compact: 210.0x160.0 mm. with a thickness of 40 mm. The second factor determining the choice is the conditions in which your car is used. If this is a rural area characterized by high dust levels, a regular anti-dust product will do. For large cities, where there is a large concentration of exhaust gases and products of industrial enterprises, it is advisable to purchase a carbon filter.

If we talk about a specific brand, then it is not at all necessary to give preference only to original products - currently there are many brands on the market offering equally high-quality and more affordable models. The main thing, as we have already noted, is compatibility in size, and we have already indicated the guidelines.

Replacing the filter

Instructions on how to change the cabin filter on a VAZ-2112 depend on how the filter is located on your car: horizontally or vertically. In essence, the differences are small, but ignorance of some nuances can lead to undesirable consequences. In any case, to carry out the replacement we need the following tool:

Phillips screwdriver;
flat screwdriver;
10mm head with ratchet;
rags;
car vacuum cleaner;
new cabin filter.

To begin with, we present an algorithm for those cases where the VAZ-2112 has an old-style cabin filter (vertical, installed on cars produced before 2003):

open the hood;
Using a 10 mm wrench, unscrew the nuts holding the facing panel;
to dismantle the frill, it is necessary to remove the decorative caps, under which the actual bolts securing the decorative panel are recessed - we use a flat-head screwdriver for this, being careful not to damage the caps themselves;
use a Phillips screwdriver to unscrew the five self-tapping screws located on the casing;
using a flat-head screwdriver, pry up and disengage the plastic clips holding the cladding (special care is required here, since the clips are fragile and can break if excessive force is applied);
we move the frill up and to the side, while the jets of the glass washer mechanism do not need to be unscrewed;
Since the filter element is located near the heater and is located vertically, to remove it, you need to grab the filter with your hand and try to turn it counterclockwise. With such an impact, he must freely leave his seat;
Installation of a new VAZ-2112 cabin filter is carried out in the reverse order. The filter itself must be installed in its original place, this time turning it clockwise until it locks into place;
Once again we check the reliability of the fixation and proceed to assembling all the fastening elements of the structure.

Now let’s describe how to replace the cabin filter on a new VAZ-2112 model (installed horizontally):

we open access to the engine compartment;
unscrew the nuts holding the wipers with a 10mm wrench; they should be removed easily, without the need to use additional tools and devices;
Using the same key, unscrew the bolts located around the perimeter of the frill;
to remove the decorative trim, you need to use a flat screwdriver to carefully pry and remove the plastic plugs, under which the self-tapping screws for fastening the trim are hidden;
unscrew the screws, remove the frill;
access to the plastic casing opens, under which the cabin filter is located - dismantle it using a Phillips screwdriver;
since in this case the filter element is located horizontally, there should be no problems when dismantling it;
in the same way, we install a new product in its regular place (the main thing is that it fits perfectly in size, otherwise the efficiency of air filtration will drop significantly);
when installing a new filter, it is necessary to observe the correct orientation - there is an arrow on its body indicating the path of air flow, from the air intake holes on the frill towards the heater;
Once again we check that the filter element is securely fixed and that there are no visible gaps and proceed to assembly in the reverse order.

Note that many car owners do not want to put up with water getting into the cabin filter of the VAZ-2112 and are fighting this problem by installing fairings on the frill that do not allow drops flowing down the glass to get into the holes in the air intake grille. This solution usually leads to a slight deterioration in the aerodynamic properties of the car and howling when driving at high speeds. But this is a completely acceptable price to pay for the inconvenience that a horizontally located filter brings to the driver.

Step-by-step instructions for making a cabin adapter

So, before you start working with metal, you should make templates for parts from paper. We print out drawings of the parts of the structure and glue them together. Here's what we got:

Printed from Compass 3D V12 1:1

After this, we take the resulting stencils, metal scissors and cut out the galvanized parts.

Next, we bend the parts in a large vice, using a wooden mallet so as not to spoil them.

Then we drill holes with a drill, metal drill bit 3.

We fasten the parts with M3 bolts.

Next, you can install our craft. First, the part for the motor. Then on top is the part with the frame for the filter.

To make installation easier, the plastic grille to protect against leaves was removed.

We treat the adapter itself with glass sealant, carefully coating all the cracks and joints so as not to siphon, otherwise the whole point of the installation will be lost.

We also treat the places where the adapter comes into contact with the car body with auto sealant (silicone will not work)

The final touch is a rubber seal on the top of the adapter to protect the hood trim.

Now you can install a cabin filter of the new tenth sample.

Bottom line: if you wish, you can also paint the resulting upgrade and begin to fully enjoy the clean air of the cabin!

VAZ-21099 cars are still very popular in Russia. These are inexpensive, fairly reliable and durable machines, well adapted to our operating conditions. At the same time, we are talking about a product from AvtoVAZ, with which few people are fully satisfied due to its shortcomings. The disadvantages of model 21099 can be safely attributed to the fact that there is no full-fledged cabin filter. The first cars produced at the AvtoVAZ plant did not even have a conventional filter element. Only after some time they began to install designs on these cars that are somewhat reminiscent of cabin air purifiers, but in reality are just a parody of the filter. Therefore, car owners had to take everything into their own hands. The most effective solution was to install an adapter for the cabin filter. Finding it is not difficult, and the installation itself does not cause any problems.

Replacing the cabin filter Lada 2109 (VAZ 2109)

How to solve a problem
Signs for replacement
Installation

The task of the cabin filter is to clean the incoming air from all kinds of contaminants, dust, and odors. Every modern car is equipped with a similar component. But the VAZ 2109 is deprived of a filter at the factory.

In VAZ 2109 cars, air enters through the air supply box into the heater fan. Because of this, the heater is regularly contaminated with leaves and all kinds of debris, of which there is more than enough on the road. Small particles fall directly into the cabin. And this is what the driver and passengers have to breathe.

How to solve a problem

Obviously, polluted air inside the VAZ 2109 is a serious problem for car owners. In such a situation, it is impossible to leave everything as it is. Measures must be taken to eliminate this deficiency.

An adapter was developed especially for nines - this is an analogue of a cabin filter, presented in the form of a plastic grille with filter elements attached to it. Installation is carried out on the heater fan casing in the area where air is taken in.

Adapter

Many people believe that installing an adapter is a complete replacement for a standard cabin filter. But how can you completely replace something that is not in the car?! This is a kind of modification that will lead to a narrowing of the air flows coming from the stove deflectors. This measure will protect against large debris, that is, we get an anti-dust component.

The positive qualities of the adapter include its accessibility, effective resistance to dust, and protection against the accumulation of deposits on the dashboard, upholstery, and glass.

Installation

In fact, installing a cabin filter adapter on a VAZ 2109 is quite simple. The most important thing here is to get an adapter. Some people make it themselves, while others purchase it from auto stores or online. Decide for yourself what is more convenient for you to do.

The adapter is installed in place of the standard stove motor casing. To mount the device, the existing holes for fasteners are suitable.
The design of the adapter includes two components, which allows you to install the unit in confined spaces without much discomfort.
It is not at all necessary to remove the cabin fan when installing the adapter.
Lift the hood, unscrew the screws that hold the frill.
Carefully remove the side of the frill from the visor.
Remove the rubber seal. It is located on the partition separating the engine compartment from the air supply box.
Remove all screws holding the factory heater fan shroud on.
Remove the cover. You won't need it anymore.
Install the back of the adapter structure first. The fasteners remain the same.
Next, the front part of the device is installed.
Using fastening brackets, the structure is connected together.
Return the side of the frill to its place.
Secure the adapter using self-tapping screws to the existing mounting holes.
Place a rubber seal on the side.
Insert into the installed filter adapter.

All that remains is to check how the new air purification system in the cabin will work. To do this, you need to drive several kilometers, feel new smells, or rather their absence in the car.

Do not confuse the cabin air filter with an air filter.

Despite its simplicity, the air filter is a very important part for stable engine operation.

And if it is, for example, in engine oil, then this indicates the presence of serious malfunctions, which, in turn, depend on which fuel supply system is a carburetor or an injector.

In general, you can’t do it without a professional master.

How to clean the air inside a VAZ 2109 car

A device resembling a cabin filter is built into the VAZ 2109 car. This is a plastic grille with filter elements attached to it. It is put on the heater fan casing in the place where it takes in air. Such filters are installed standard on the VAZ 2114, VAZ 2115 models. But it cannot be said that such a device is a complete replacement for the cabin filter on the VAZ 2109. In this case, the air flow from the heater deflectors is greatly narrowed, and it only protects from large particles. In fact, the device is an anti-dust filter. Replacing the cabin filter on a VAZ 2109 with an adapter from a VAZ 2110 car has become the most acceptable solution to the issue of cleaning the air in the cabin. The adapter can be purchased from the manufacturer or made by yourself. The device retains dust well and prevents its deposition on the control panel, the inner surface of the glass, and the upholstery. And most importantly, the driver and passengers will breathe clean air, free of dust and odor.

Types of cabin filters

These products are usually divided into two large subcategories:

conventional dust filters designed to filter the external air flow from small debris and dust. They consist of two layers of special filter paper or synthetic fiber: the first is for rough cleaning, the second is for finishing. Such filter elements cope with their task perfectly, preventing dust from entering the cabin;
Carbon filters contain a third protective layer containing activated carbon. Thanks to this, such a filter is able to retain (adsorb) many volatile substances and microorganisms, protecting the interior from the penetration of unpleasant odors from the outside, and also preventing many pathogenic bacteria from entering the car.

The efficiency of cabin protection of modern filter elements is about 95%, and this is a very good indicator. It is almost impossible to achieve absolute purification by filtration, since as the density of the filter paper increases, its ability to pass air deteriorates.

By the way, with the ventilation system turned on, in just one hour about 200 thousand liters of air pass through the VAZ-2114 cabin filter - you can imagine the load placed on it and why it is so important to maintain good throughput of the filter element. Unfortunately, over time, filtered debris inevitably clogs the pores of the paper, which becomes the reason for the need to periodically replace the cabin filter.

Note that many owners of 2114 consider the original filter element to be insufficiently effective, upgrading it by installing an additional fabric layer. This certainly improves the quality of filtration, but at the same time it worsens the air flow, and this causes more harm than good.

So such experiments should be abandoned. Moreover, if you are not satisfied with the original filter, it is quite possible to purchase a non-original product

Moreover, a filter element from another brand or model may well be suitable - the main thing is that it matches in size (critically important - in width and height, the thickness may be slightly smaller or larger). Due to its low cost (around 200 rubles), most VAZ-2114 owners prefer the VF-014 product, which is not a carbon filter

Adapter and its advantages

To solve the problem of the lack of effective air purification in the cabin on VAZ-21099 cars, the most correct solution would be to install an adapter. Moreover, finding this adapter or adapter for a full-fledged filter element is not difficult. The easiest way to purchase it is through trusted suppliers. Such parts are not popular among scammers trying to counterfeit adapters. Therefore, the vast majority of proposals are of decent quality. A similar adapter is widely available on sale and costs about 2 thousand rubles. Yes, you can try to save money and try to make the design yourself. But there are a number of pitfalls that may not justify your investment in developing your own adapter. That is, it is objectively more correct and rational to buy a ready-made adapter from the manufacturer. This will allow you to operate your VAZ-21099 with a cabin filter of good quality and high efficiency.

The adapter will be mounted in place of the standard casing that covers the electric motor of the heater on the VAZ-21099. Moreover, standard holes are suitable for installation. You definitely won’t have to drill anything additional or dismantle half of the interior. The design of the adapter for the cabin filter is presented in the form of 2 parts. This was done for more convenient installation, since you have to work in a fairly limited space of the air supply box. The adapter box itself is made in the form of a fairly voluminous product, the basis of which is metal coated with powder paint. Although on sale you can also find analogues that are made of galvanized steel. There is no fundamental difference between them.

The adapter parts are divided into rear and front. It is into the latter that the cabin filter is inserted. Rubber seals are provided on the joint planes of the two parts of the adapter. They allow you to ensure the required degree of sealing of the housing during its assembly. Thus, the casing prevents water and moisture from penetrating inside, additionally protecting the electric fan of the stove itself. Similar seals are available on the lower plane of the adapter structure. The sides on the front prevent water from getting into the filter when the car is being washed or driving in heavy rain. The design is oriented in such a way that the filter is located forward in the direction of travel of the vehicle. This allows you to use corrugated or accordion-type cabin filters, just like those used on VAZ-2110 cars. In addition to the metal structure itself, you also receive all the necessary fasteners and instructions from the manufacturer.

The adapter can be considered a modernized heater fan casing. By installing the adapter, it becomes possible to use cabin filters intended for the tenth AvtoVAZ family, that is, for the VAZ-2110. The filters themselves are inexpensive, so the total cost of purchasing all components will be insignificant. By installing an adapter or adapter for a full-fledged cabin filter on your VAZ-21099 car, you get a number of advantages. Namely:

There will always be clean and safe air in the cabin. This is due to the good performance of the filter itself, which can trap small debris, dust and smoke coming from the exhaust pipes and from under the wheels of vehicles in front.
The efficiency of air passage through the filter increases with simultaneous highly effective cleaning. That is, the air flows will become more intense, in winter the interior will be able to warm up faster, and the efficiency of your electric heater fan will increase. This effect is due to the fact that the new cabin filter has minimal air resistance. This is explained by the material used and the thoughtful design of the consumable.
Having an adapter in the engine compartment, it will take literally a few minutes to replace the filter itself located inside. This will make servicing the cabin air filtration system as simple as possible and accessible even to beginners.
Basic installation. To install the adapter for the cabin filter in its new place, you will need to perform a minimum amount of dismantling work, followed by no less simple reassembly.

Types of cabin filters

There is no official classification of products designed to provide high-quality protection of the car interior from dust and other pollutants that are abundantly present in the atmospheric air. However, experts distinguish two large subgroups of cabin filters:

conventional dustproof ones, the main task of which is to prevent microparticles of a certain size from entering the cabin;
coal, designed, among other things, to prevent external odors and substances harmful to human health that are in a gaseous or suspended aggregate state from penetrating into the car.

Conventional filters are made from special paper or synthetic fibers. The first such car filters were single-layer, but now the de facto standard is the presence of two layers: the first carries out rough cleaning, preventing small twigs, insects and other contaminants of similar sizes from penetrating further. The second layer performs final cleaning of the inlet air flow from fine particles and dust.

The advantage of carbon filters is their ability to resist the penetration of unpleasant odors from outside. This is achieved through the use of certain additives and activated carbon in the third layer. As is known, activated carbon is an excellent adsorber that qualitatively absorbs a wide range of volatile substances. It also does not allow the passage of the smallest particles of soot present in car exhausts, as well as powdered rubber - the result of abrasion of car tire treads on the road surface. A carbon filter can be distinguished from a regular one purely in appearance: it has a darker color, while a regular one is made from white synthetic fiber or special paper.

Domestic car enthusiasts are used to saving on everything they can. Even if he belongs to the category of very disciplined drivers, accustomed to performing all maintenance operations on time. In particular, it is not uncommon to reuse cabin filters after cleaning and washing them. There are also individuals who do not want to spend even 500 rubles on this consumable, preferring to make it from available materials - foam rubber, padding polyester and the like. Such a replacement of the VAZ-2112 cabin filter, as a rule, is characterized by extremely low efficiency - homemade filters retain no more than 20-30% of dust, which makes such an operation pointless.

Adapter

Alas, the quality and efficiency of the standard cabin filter provided for the VAZ 2114 leaves much to be desired.

Essentially, it is a strip of filter material that is located between two plastic grilles. The effectiveness of this design is insignificant, which forces car owners to take certain measures.

The best measure is to install a filter adapter. Making it yourself is not difficult, although there are other ways to obtain this design.

Adapter drawing example

Thanks to the adapter, it becomes possible to install a truly effective air purifier for the cabin, which retains the smallest particles and does not allow the driver and passengers to breathe dust.

Externally, the adapter is an improved housing for the interior ventilation system with a filter built into it. The design consists of two elements - the rear and the front. A filter is inserted into the rear component, and the joints between the adapter parts are sealed with rubber gaskets. This ensures the necessary tightness. The design nuances will allow you to avoid moisture penetration even when washing the car.

When planning the installation of the adapter, experts strongly recommend using a pleated cabin filter borrowed from the VAZ 2110.

The simplicity of the adapter design makes it possible to replace the filter with your own hands in the shortest possible time. And during installation you do not have to remove the heater. So this is an ideal solution to significantly improve the ventilation system of your VAZ 2114.

Options for obtaining an adapter

If you have made the right decision that you want to get an adapter for your VAZ 2114, you need to decide how exactly you will get it.

There are three main options for this.

You should start making your own adapter only if you are completely confident in your own abilities. Spend the money you save on purchasing a high-quality carbon filter from a VAZ 2110.

Making the adapter

The instructions for creating an adapter with your own hands are quite simple. Another question is how accurately you can implement your plans.

Find diagrams to create an adapter. Now there are many of them on the Internet. Just keep in mind that you need an adapter specifically for the VAZ 2114.
Make a layout out of paper so that you understand exactly where each part goes and how they are connected to each other.
Stock up on the required amount of stainless or galvanized steel. Some people use plastic, but it is a little more difficult to work with, plus it can cause problems when getting bends.
Cut out the necessary adapter elements from the material, guided by the drawing and layout.
Use a vice and mallet to make bends. The walls will be thin, so do not use a metal hammer. It is better to take a wooden or rubber mallet.
The parts are connected using M3 bolts or rivets.
The advantage of rivets is that you do not need to drill holes in the metal. But they also have a drawback - a high probability of damage to a thin sheet of metal.
At the last stage, carefully treat all joints, connections and holes with sealant. This will allow the structure not to make unnecessary noise while driving.

Finished design
The manufacturing process will take at least 6 hours. Plus, you will additionally have to spend time studying diagrams, drawings and creating a layout. So be patient.

What does the cabin filter adapter look like and what functions does it perform?

The cabin filter adapter allows you to install a modern cleaning element in your car that will retain dust and prevent it from settling on the inside of the windshield, dashboard and interior trim.

The product is a modernized casing for the cabin ventilation system with the function of integrating a cabin filter from VAZ 2110 cars. It has a detachable metal structure, consisting of two parts - front and rear, into which the filter is installed. The joints of both parts of the adapter are sealed with rubber gaskets, which improve the tightness of the structure and prevent moisture from entering the interior blower fan. The lower plane of the adapter is also treated with the same seal. The sides of the front part are responsible for keeping the filter dry when it rains or when washing the car. The location of the adapter in the car ensures that the filter is installed forward in the direction of travel of the vehicle. This orientation of this design allows the installation of a pleated cabin filter of the tenth Samara family. At the same time, removal and installation of the filter component for its periodic cleaning and replacement can be done in a few seconds. The adapter can be installed on cars with various modifications of the standard casing, and all thanks to the universal fastening of the adapter. There is no need to remove the heater fan during installation.

How to replace the cabin filter?

The cabin filter is a rectangular frame that can be made of high-density cardboard, plastic or non-woven material. In the middle of the frame there is a filter element made of different materials, for example, paper or fine-fiber non-woven material. And along the perimeter of the frame there is a seal.

Experts and car manufacturers recommend changing the cabin filter every 10,000 kilometers. They explain this by saying that over time, a layer of dust accumulates on the surface of the filter paper, which is an obstacle to the heater fan drawing in the required amount of air.

So, the fact that your cabin filter is dirty may be indicated by the lack of fresh air in the cabin, fogging of the windows in the car, poorly functioning air conditioning in the summer, or poor supply of warm air to the deflectors in the winter.

This happens less often in foreign cars due to the fact that many automakers, especially Japanese ones, simply do not install a cabin filter in their cars to avoid glass fogging and other problems.

But this does not mean that there won’t be dirt - there will be, it will just penetrate deeper - into the air conditioner evaporator, and installing a cabin filter yourself won’t help here anyway. The only thing that can be done in such a situation is to dismantle the air conditioner and clean it, having first pumped out the freon from it.

If the cabin filter is present in your car and is dirty, then it is better to replace it with a new one.

How to replace the cabin filter with your own hands, instructions

The first step is to start by dismantling the windshield wiper arms and plastic “protection”. For injector “ten” engines, you initially need to remove the sound insulation (it’s located on the left), located between the engine compartment and the heater, but on the right side, dismantling is not required.

Then you should get rid of the mounting brackets, for which we unscrew the two screws located at the bottom and move the air collector cover to the left and remove it.

On the front side of the heater you will see a rounded protrusion, which is located in the center, and at the top there is an air collector hole. Older car models in this location have a recirculation switch cover, which also needs to be removed. Now you can begin to directly remove the old cabin filter and install a new one.

Replacement frequency
