The modern device of this element of the air system involves several layers that serve as a barrier to garbage. It is considered normal to block particles up to 5 microns in diameter.

An additional layer in the design is activated carbon distributed over the area. Its task is to prevent soot particles and soot from entering the cabin, as well as blocking certain types of gases.

Hybrid models have maximum efficiency. In addition to the coal layer and mechanical protection, such filters have antimicrobial protection and blocking from electrostatics. In some cases, there is an additional aromatization of air.

No self-cleaning of such air cleaners occurs. They should be replaced, since the passageways become clogged with dirt, the effectiveness of the remaining filter layers decreases with time, moisture is retained, and an unpleasant odor forms in the cabin.

Terms of operation

It is recommended to change the most popular simple paper filters in the form of a corrugated cassette after an average of 5000 km of run. If the operating conditions are extreme, then inspection and replacement are carried out at a more frequent frequency.

You need to know that regular trips on a dusty primer lead to quick clogging of the filter.

Self replacement

It is possible to find out where the cabin air filter is located in the VAZ family of vehicles with the help of an automobile atlas. Indeed, on the “old” “dozens”, produced before 2003, it has a vertical location, and on later machines, the designers installed it horizontally.

To replace, you need to take the key for 10, unscrew the nuts. Then remove the screws and remove the latches. The washing system does not have to be affected, it is enough to loosen the plastic to release the passage. Next, push the hand into the heater, and, turning the corrugation, we get it out. Now we put the new filter back, checking the density of the installation. After that, fix the plastic cover.

In foreign cars, such as the Nissan Tiida, it can be positioned in such a way that its replacement passes through the salon. To do this, remove the glove box and change this item.


The operation to replace the cabin filter does not require highly skilled performer. Everything can be done independently.
