Salon filter: where is it, how often change and why need. Salon filter: where is it, how often change and why do the types of salon filters

The air in the interior of the car comes from ambient Constantly through 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. Breathe such air is unsafe, and to hold harmful impurities is established salon filter.

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 road road 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 exposure toxic substancesThe harm to the respiration to the driver's breath is applied dust microparticles from tires, soot, asphalt and other things.

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. Unambiguously say where the cabin filter is located only specific model The car 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 the air filtration element entering the cabin is installed on the driver side, for example, under 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 View 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.

If I do not see the subject, it means that it does not exist. This rule is widely used by us under normal conditions, but when we are talking about a micrometer, the rules that contradict common sense come into force here. Many people, without seeing anything in the inhaled air, except except for dust particles (and even then under certain conditions of lighting), they are confident that nothing-threatening for health is contained in it. And deeply mistaken. We will not talk about flu strains, cholera, African plague and other similar things - today it is really exotic. But what enough on the streets big CitySo it is a whole spectrum of microparticles, which are very well distinguishable only with multiple increases. We are talking about ordinary dust, about the rubber crumb that falls into the air from automotive tires, about the smallest particles of asbestos peeled from brake shoes, about heavy metals, soot, high molecular weight hydrocarbons and carbon black gas - combustion products. Their concentration on urban roads exceeds all conceivable norms, and it is naive to believe that breathing every day this rattling mixture, you will not feel any consequences for the body. It is even more irresponsible to think that, being inside the car, you are reliably protected from this cocktail. It is exactly the opposite to the contrary - it is estimated that in the cabin vehiclenot equipped with filter, concentration harmful substances exceeds their number on the city highway 25 times!

Installation of the coal salon filter.

Purpose of salon filter

Fortunately, on most cars recent generations Such protection is present in the form of a salon filter, which can be installed in different places, but most often in front of the furnace radiator. In this case, the air heats up after cleaning and enters the interior, distributed through the air ducts. This is the most successful design solution, since if the filter was standing after the radiator, the air would have managed to cool. In addition, in this case, the radiator is contaminated inside, which significantly increases the service life. In addition to small mechanical impurities, such as pollen plants and dust, the SF detains both volatile substances, as well as high molecular weight gases, and models having a layer with activated carbon, also oppose the penetration of unpleasant odors into the salon.

Types of salon filters

The principle of action of any filter installation is unchanged: the working element standing on the path of the uncleaned air flow, thanks to a finely stubborn structure, detains particles of a certain size, freely flowing air. Modern capable of delaying particles of order of about 0.1 μm of which sufficient to screen practical any mechanical impurities. The classification of salon filters by the filtering method involves their division into two more groups: mechanical and adsorption. The first are conventional paper / synthetic corrugated products, which have a certain cell size between adjacent fibers through which air passes, and dust - no. Adsorption SF, besides an ordinary filter element, have a layer with activated carbon, the principle of operation of which is based on another chemical phenomenon - the ability to absorb other substances, including volatile compounds and gases. In other words, they absorb and unpleasant odors, which is an important factor in the contemporary metropolis.

By type of constructive execution, the SF is divided into body and cartridge type. Cabinet devices are a soft filter element enclosed in a hard frame (plastic or cardboard). This filter is easier to insert on planting placeBut provides a greater degree of tightness. Cartridge products are a corrugation without a rigid edging, with soft cardboard sides, located around the perimeter or sides. They are cheaper than case of body analogues, and when the sizes are lost, you can always purchase a more overall option that is easy to shorten. The prevalence of frameless salon filters is higher, but this is, as they say, the case of taste.

Since modern cars are literally stuck with a variety of nodes and aggregates, find the place for the filter is not easy. This is how it is possible to explain the fact that the form of the SF is different, from square or rectangular to round, in the form of a trapezium and other exotic outlines. It is dictated by the presence and configuration of free space, but it greatly makes it difficult to replace the devices of the devices. Many drivers, especially those who have never ever had the case, arise, arise with the understanding of which side to put coal, especially if there are no explanatory inscriptions and pictograms. We will look at this question a little later.

Coal filters: high quality step forward

The cabin filters began to be installed in serial models relatively recently, thirty years ago. Over the past time, they were pretty evolved, having passed the way from primitive paper filter elements with minimal efficiency, to the current multilayer structures that protect against most of the extraneous impurities present in atmospheric air. The degree of filtering at the current coal filters So large, which allows you to delay particles of molecular sizes. Unfortunately, it is impossible to infinitely improve this parameter, otherwise the filter will not be able to pass and air. That is why even the most perfect coal filter is powerless against harmful gases, whose molecules have small size, for example, against carbon dioxide, but they are struggling with another way - including exhaust system Catalytic neutralizers absorbing such gases at the release stage.

However, as the coal filter of the pores of its filler is gradually clogged by those particles that it is designed to catch, worsening air passivity, and as soon as the saturation turns out to be critical, the reverse process can begin - desorption, in which all these accumulated substances leave the filter by clogging by different paths everything around. That is why coal on time, without waiting for critical clogging. Another question is the correct definition of the moment when it is necessary to replace. Some particularly frozen cars are equipped with sensors that signal the need to produce a speedy replacement. Everyone else has to be observed to observe the regulatory deadlines, which is far from always justified, or focus on symptoms indicating the deterioration of the cleansing properties of the cabin filter.

In most cases, the procedure does not represent difficulties, since it is located in the area of \u200b\u200bthe furnace radiator. But even if access to the cabin filter is facilitated (many models of the car it is located either directly in the glove box, or behind the glove compartment), this does not mean that it will be uncomplicated in the place of the closed SF. The fact is that it is necessary to follow the desired orientation of the filter element. This is especially important if the coal filter is used, due to the reasons described above. Well, if the design of the SF does not allow you to install it not by the rules, but it happens rarely. Rectangular cartridge filters (they are also called cartridges) usually allow symmetry that allows them to be improperly installed. As a rule, on the original products there are arrows indicating right direction Airflow (the edge of the arrow is always directed towards the deflector, that is, to the cabin).

But such designations may not be. In this case, you can use a universal rule regarding only coal filters: the dark side (with a coal layer) filter is placed to the air duct that provides air flow from the outside. Obtaining ordinary dust filters both sides are the same, but there is no such rigor to install the device, so the error will not have such unpleasant consequences.

About that, cabin filter, many car owners are thinking only after there are problems with the flow of clean air into the interior of the machine. To deal with the change of consumility, it is necessary for motorists who, with the onset of the cold season, regularly have to include the heating system on a constantly increasing speed. Most of the manufacturers of domestic and foreign vehicles are recommended to conduct a filter change procedure after 15 thousand km. In the following article, consider the principle that allows without certain knowledge and skills to dismantle the previous cleansing element and install a new one.

Change the cabin filter in the car is very easy. It is much easier and faster to do it yourself, rather than give a car to the service

Replacing the component in the car with air conditioning

Installing the cabin filter in a vehicle in which there is air conditioning, has several features. First of all, it should be noted that the manipulation on such machines is a bit more complicated. The main task of the car owner is to get to the replaceable item, which is located for. The device from above is closed with a noise absorbing casing.

You need to know how to properly implement the task, in view of which it should be strictly followed by the instructions below.

• initially, the self-tapping screws are dismantled through which the protective casing is attached, subsequently removed from its fasteners. Perhaps the motorist will have to remove the nozzles that it is advisable to disconnect in advance, which will help get rid of their deformation and damage;
• open access to the plug of the cleaning system component, which has a fastener in the form of a self-drawing or a latch ,. After that, you can easily remove the spent device using a special label. In most models, the flexion of the slots helps to extract the device. After the previous element is outside, it is necessary to place a new one and collect previously dismantled parts in the reverse order.

Before installing a new unit into the system, the car owner should know which side you need to position the device. Most often, the manufacturer plays the parties to the device, so you only need to pay attention to the letter notation on the body of the product. An appropriate element of the design element with a screw with self-drawers, which will ensure reliability of fixing.

Change cleaning device in car without air conditioning

As mentioned above, install the cabin filter into the car without a pre-installed air conditioner is much easier and easier.

First of all, it is necessary to open the hood and remove the protective lattice, which is located opposite the passenger chair. As a rule, it will be there a replaceable device.

Fixed bolts holding a component of the cleansing system, the unit can be removed outward. In the purified seat, in which, as a rule, there are clusters of dirt and dust, you need to insert a new cleaner device. By the way, it is possible to clean the location of the device by a vacuum cleaner, pre-turning the mode of medium power.

Conclusion

The above recommendations will help to understand how to deliver the cabin filter. In fact, it is a simple task whose solution can find absolutely any motorist. It is worth noting that it will take about 10-20 minutes to work, which is much less than the time required for a trip to the service center and waiting for your car. Along with moral satisfaction, the auto owner independently carried out the replacement will receive cash savings.

The air entering the auto cabin through the air ducts of the fan must contain the required volume of oxygen. It does not simply create a comfortable setting inside the cabin, but also provides the extension of the operational terms of important units and knots of the car as a whole. And therefore completely in vain, many motorists consider the salon filtering device as sufficiently significant element in order to devote to him special attention. In this article we will tell, where the cabin filter is located, what filters are equipped with modern cars And how to change it if necessary.

In the thick stream of cars towards any vehicle, a mixture is sent exhaust gases From the other participants in the air. It is extremely dangerous to breathe such a "runday" mixture, so the air filter of the salon is put in the car to delay the malicious impurities.

Installing the cabin filter

The simplest paper filters began to put on cars since the 80th year of the last century. They were an accurate copy of the filters used in engines that suggest mechanical cleaning. After some time, special cartridges were presented with two layers of cleaning. Key advantage Such a filter was that the first layer was detained by a relatively large trash, and particles, less than 50 microns, sedated in the following layer.

Later, filters equipped with coal elements were created for carswhich much better absorbed dust particles. Nowadays, filters that combined the best qualities of their predecessors are most effective and expensive. And the most demanded devices remain filters with a coal cartridge that have an optimal value for money.

How filter works

Air penetrates into the interior of the car through the air intake holes in the heating system. It can come in two ways:

• samoter;
• forced injection with a fan.

Based on its functional, the filter is installed in the heating system housing. Classic filtering devices are performed from the finest paper, which is filled with electro-static charges and is impregnated with phenoloaldehyde fluid.

This filtering device technology implies not just the holding by the device of large grainy air impurities, but also attracting smaller particles, in addition, the unpleasant smell is neutralized.

Installation of filters is most effective for people who suffer from diseases of the respiratory organs (asthma, allergies, etc.), reacting to all sorts of smells, dust, pollen and other stimuli inhaled air.

Principle of filter operation

Types of salon filtering devices

The air filter of the cabin is a rectangular block having defined dimensions. Each device is equipped special Material which performs filtering and has a view of a corrugated plate. The frame is made from plastic, and its main purpose is to protect the plate from the roaming and its hold in the nest.

By type of filter material used, the device can be divided into several varieties.

Barrier filter

This instance is made from the finest paper or the web (natural or synthetic). Similar filters designed to hold the smallest mechanical suspension in the air. They purify the air flow, which is served inside the cabin, only from dust (sometimes from small insects).

Coal filtering device

A coal is applied to the filter material of such a device with a small layer. Exactly it promotes the absorption of dangerous impuritiescontained in air and neutralization unpleasant odor. Such a filter is characterized by improved filtering qualities, if compared with its barrier analogue. But it is important to know that from time to time the filter properties of a key element (coal) are lost, which leads to their transformation into a regular filter.

Saloon air filter

Coal element with special coating

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

Electretty filter element

A similar device, in addition to the ordinary linen layer, is equipped with an additional electric-charged layer of thin fiber. The first of the layers is assigned a mechanical filtering function, while on the second - attracting microscopic particles of all sorts of impurities air. Manufacturers of such devices declares that this filter delays:

• 99% of a variety of particles in size from 5 to 100 microns. These impurities include pollen, fungal disputes, dust of various origin;
• over 65% of particles having a diameter from 0.3 to 1 μm (smoke / soot / bacteria);
• up to 35% of microscopic particles having dimensions equal to the cell of the micron.

Combined type filter

This device combined coal elements and electret layers. The device has several degrees of cleaning. In addition, there are multilayer filtering devices on sale. They have a layer of mechanical cleaning in combination with an electrostatic, antiseptic and coal layer.

The most in demand from Russian motorists barrier and coal filtering devices, as they have a minimal price. Filters with anti-allergenic characteristics are premium class devices.

Salon Filter Function

When installing the cabin filtering device, it is important to know that any filter, regardless of the type and cost of the device, is a one-time element that is subject to a mandatory replacement after a certain period of time.

Place of placement and frequency of replacement

Place installation of the filter element

Despite the differences in the filter structures different types and different manufacturers, by appearance Filtering devices, often not too different from each other. Although the installation site of the filter element is different in the car different brands. The most common options are:

• under the main panel, for the "glove compartment", opposite the passenger seat;
• in space under the hood of the car from the driver's side;
• directly at the steering column on top of the pedals.

Depending on the location of the filtering device (This is affected by the vehicle model), it is distinguished by the procedure for its replacement. And therefore, when it is necessary to replace, it is better to seek the services of the Masters of the Car Service. Otherwise, there are certain risks to deform the edge or the framework of the filtering device, it is not sufficiently tightly to take the device into the socket or damage the planting place of the filter element.

Filter location

During operation and constant work in the corrugated element of the filter accumulates garbage, this leads to his incorrect work and implies a replacement this device. The timing of filter replacement is indicated in the operational documentation of the TC and, as a rule, coincides with the period of planning service.

Note that sometimes replacement air filter It takes much more often. Suppose when the TC is used in excessive gas and dusting conditions. Reducing the period of operation of the filter element is recommended when:

• continuous movement on the car by primer;
• constant trips during the flowering of plants from which many petals and fluff are reset;
• movement in large cities, where the roads on the roads are common.

In addition, the requirements of the device itself affect the regularity of the replacement. So the good filter element from the proven manufacturer will serve 15-30 thousand km, then the fake device may not work and 50% of the term declared in the Regulations.

Replacing the filter

The fact that time has come to change the filtering device can be determined by some indirect features:

1. The air supplied to the salon has an unpleasant smell.
2. At the time of turning on the fan, dust appears.
3. The power of the air flow during blowing decreased, the air conditioner / stove works worse.
4. Glasses in the car's cabin began to fogged a lot because of much moisture.

Violation of the replacement of the filtering device leads to the accumulation of dirt, conducive to the development of fungus, mold and bacteria, which are intensively distributed across the system ventilation channels. In such conditions, the device turns from the air cleansing element to the source of the spread of various diseases. You still need to understand that cleaning with a vacuum cleaner, wash or wash does not restore the properties of filter materials.

How to change the salon filtering device

In fact, this element is simply changing, it is only necessary correctly define its locationAnd then get it. It is extremely important, removing plastic inserts, followed by a filter, do not damage the snap-on elements that are fixing them. It is advisable to read the instructions for the car several times, where it is described in detail how to remove the mount than to restore it or completely replace the element due to breakage.

Dismantling the exhaust filter, do not hurry to put on his place new element. Specialists advise you to take advantage of the vacuum cleaner or in other ways clean the place where the filtering device stood. After that, you can start installing a new filter. At the same time, do not forget to look at the pointers available on the device - they will indicate which side to correct the filtering device.

Old and new filters

Some companies indicate the installation schemes of the filter device. Usually, this is an arrow, which indicates the direction of air flow: when the pointer is directed down, then the air flow comes from above.

In the absence of any pointers, you should install which side of the grooves have more in-depth. It is through this side that there is air to clean it. The logic is such that grooves having a greater depth, suggest a longer garbage collection, leaves. Consider how the filtering device changes on some models of machines.

Change the filter on Toyota

IN models Corolla The cabin filter is located At the feet of the passenger behind the discharge box. Nothing is required for changing the filter, only a new device.

On both sides of the bad drawer there are special latches. When disgraving, the mailboxes are slightly lowered. This will give access to the filter block. The block is held on 2 tag, which must be squeezed. Now nothing will prevent the installation of a new filter device.

If the box is set below, you should check the micro-elevator (small piston) drive, which provides smooth when the drawer is opened. Most likely, he elementally flew out of the attachment.

How to change the filter

Change the filter on Chevrolet Cruze

Sequence of actions when replacing The filtering device is as follows:

1. From the sides, inside the broad box it is necessary to remove 2 latching limiters, slightly moving away, and then pulling it to yourself.
2. From the right edge to sweep the stroke limiter.
3. When the glove box goes out, the plastic cover of the filtering device will be visible. An element change can be made after removing the lid, which is held with three snap-on elements.

Change the filter on Daewoo

In the model Lanos. internal filter installed in space under the hood. Actions to replace the filter element are performed in such a sequence.
