Due to poor air quality, everyone wears masks, and cars also have masks. This mask is called an air filter, which means air filter or air grid in local dialect.
It is used to filter out particles and dust in the air to reduce engine wear and ensure normal operation, just like a car mask.

zuerst, how long does the lifespan of an air filter last?

Erste, let’s take a look at how long the lifespan of an air filter is under normal conditions.

The air filter for household cars is usually dry and has a service life of about 20000 Kilometer. Zum Beispiel, maintenance manuals for models like the Sylphy and Lavida require replacement after 20000 Kilometer.

Tatsächlich, the service life of air filters is closely related to the environment of the car. If the car is frequently used in areas with heavy smog and sandstorms, it may need to be replaced after 10000 Kilometer, or even less than 10000 Kilometer.

So it’s best to check every maintenance to see if the air filter is clean. You can’t just rely on whether the mileage has been reached, but also consider your actual usage situation.

Letztendlich, even food packaging has “patterns for reference only”, so the complex mechanical structure of cars needs to be analyzed on a case by case basis.

After the air filter gets dirty, it is indeed possible to clean it and continue using it, but it should be noted that the performance of the cleaned air filter is not as good as that of a brand new one, and it needs to be checked regularly. At most, it needs to be cleaned three times before being replaced.

In addition to the dry air filter used in household cars, there is another type of wet air filter that is not commonly found in household cars, which is divided into oil immersed and oil bath types.

This type is usually used on construction machinery and heavy trucks. It can be reused as long as it can be cleaned and maintained, but the filtering effect is not as good as dry type.

And it should be noted that although dry air filters can be cleaned, it does not mean that they can be directly washed with water and then hung there like clothes.

Most car air filters nowadays are made of paper, and washing them directly with gasoline or water may cause damage. The breathability of the air filter may decrease, and even malfunction may occur.

The most common cleaning method is to use an air gun to blow away the dirt, but the pressure of the gun should also be noted, generally controlled at around 0.2-0.29 megapascals, which is called 2-2.9 kilograms in local dialect.

When blowing, attention should also be paid to the direction, blowing from the inside to the outside. If the direction is reversed or the airflow is too strong, it may also cause damage.

And the air filter of this dry paper cannot be washed with water, including the possibility that the drain hole is blocked or the cover in other parts of the car is not properly closed, causing water to enter the air filter. This can result in a decrease in performance or even render it unusable.

Zweitens, the impact of damaged air filters on cars.

If this air filter is broken, it will have an impact on our car, after all, it is also an internal component of the car.

The first thing that will be affected is the engine, which can lead to accelerated wear and carbon buildup.

The service life of internal combustion engines depends on the speed of wear and tear, and there are many factors involved in wear, but particle wear is the primary factor among all wear factors.

The main source of particles causing particle wear is brought in by the media used in internal combustion engines (air, Kraftstoff, lubricating oil), and the filter is the component that eliminates particles from the media.

So if there is a problem with the air filter and a large amount of particles enter the internal combustion engine, its service life will be affected.

Just like wearing a mask, if the mask is broken, it won’t be able to filter out the dirt in the air, and you’ll feel dust entering your throat. Wearing a mask is meaningless.

Another issue is that the engine’s intake duct can also become dirty. Dust not only enters the engine, but also remains on the intake duct, polluting it.

Long term use of such a broken air filter, even without it, will cause the intake duct to become dirty and still have an impact on the engine.

It’s still similar to using a mask. If you use a dirty mask, not only will your throat be bad, but your respiratory tract will also be affected.

So if you feel that the air filter is dirty, the best way is to blow it with an air gun. Do not wash it with water or other things, as it may cause damage.
