The durability of the climate control system and the comfort of passengers directly depend on the condition of the air barrier, which protects the cabin from dust and exhaust gases. For the owner. Skoda Octavia A7 regular inspection and timely replacement of the filter element are not just a recommendation, but a necessity that prolongs the life of the air conditioner evaporator. Ignoring this simple maintenance can lead to an unpleasant odor, fogging of the glass and a decrease in the efficiency of the oven.
Many car owners mistakenly believe that if the airflow has not weakened, then nothing needs to be changed. However, even a visually pure element can be clogged with fine dust and allergens that are not visible to the naked eye. In a modern city with high levels of air pollution carbon cabin filter ceases to cope with its functions after 10-15 thousand kilometers of mileage.
In this article, we will discuss in detail how to choose the right consumables, where it is located on the Octavia A7 How to perform the replacement procedure yourself, saving money on visiting the service center.
Why change the filter and what types are there?
The main task of filtration is to clean the air entering the car cabin from mechanical impurities, pollen of plants and harmful chemical compounds. Nana Skoda Octavia A7 There are two main types of filter elements, which differ in composition and functionality. Understanding the difference between the two will help you make an informed choice when buying.
The first type is paper-filter. It effectively traps large dust, down and insects, but is practically useless against gases and unpleasant odors. This option is suitable for drivers who rarely drive in traffic jams or near large industrial areas, and for whom the priority is the maximum cost of consumables.
The second and more preferred option for Russian operating conditions is carbon filter. In its structure, a layer of activated carbon is added, which works as a chemical sorbent, trapping nitrogen oxides, sulfur and carbon monoxide. If you are often stuck in traffic jams or driving for freight transport, installing a coal cell will be critical to your family’s health.
In addition, it is worth paying attention to the design of the filter frame. A rigid cardboard or plastic frame provides a tight fit to the body, preventing unfiltered air from sucking on the edges. Savings on the quality of the frame can lead to the fact that even an expensive filter will work inefficiently due to the formation of gaps.
Watch the condition of the filter, as its clogging increases the load on the electric motor of the fan of the heater, which can lead to its premature failure.
Symptoms of pollution and diagnosis
To determine the need for replacement can be a number of indirect signs that become noticeable during the operation of the car. The most obvious signal is the appearance of a persistent unpleasant odor that does not disappear even when air recirculation is turned on. This is a sure sign that moisture has accumulated in the filter and mold or fungus has begun to develop.
The second alarming symptom is a decrease in the intensity of the blowing. If you turn the fan on at maximum speed, and the air flow from the deflectors seems weak, then the filter resistance has become too high.
