The car carbon filter can usually be replaced every 10,000 kilometers or so. Simply put, every time you maintain your car, you can replace it. Secondly, the high-pressure air duct can easily affect the surface structure of the car carbon filter, so that the car carbon filter loses the ability to filter, which may cause trouble to the vehicle.
The car carbon filter is used to filter the air conditioner, so even if it is never changed, it will not cause damage to the vehicle, but it will lead to poor air quality in the car. Therefore, there is no need to have a fixed time for car automotive cabin filters replacement. You can replace it when you feel that the air quality in the car is not good and the car smells bad. The car carbon filter is generally in the co-pilot glove box. It is difficult for you to use a blower to blow the old car carbon filter, because the air conditioner filter is in a humid condition and may rot to a certain extent after a period of use. At this time, you can blow it with a high-pressure blower. The car air-conditioning filter is not formed at all, so the air-conditioning filter is only changed without cleaning. It is recommended to replace it with a new one every summer before the peak period of use.
Many friends have the habit of cleaning the car carbon filter regularly. For example, before the maintenance time, take the high-pressure air duct of the auto repair factory and blow it against the air filter in advance. Of course, this operation can indeed clean up the floating ash on the surface, but it is only in the position that we cannot see with the naked eye (such as the gap on the air filter) will cause new problems, so it is better that the car carbon filter such as the passat cabin filter is full of floating ash, and it is not necessary to clean it. The surface floating ash is not terrible, but the surface of the car carbon filter blown by the high-pressure blower is terrible.
1. When the vehicle is running normally, the car carbon filter has a very large impact and contact area, so the pressure formed is relatively low, generally between 6-7 kPa. However, the high-pressure air duct in the auto repair shop has a small opening and a large pressure. Such a small opening blows against the car carbon filter, and the pressure in the windward position can reach 300-400 kPa. Such a large pressure change is enough to cause serious damage to the structure of the car carbon filter itself. The pores on the surface of the filter paper will be completely enlarged by the sudden increase of the pressure and thus lose the filtering ability, and the silica particles attached to the surface themselves are extremely difficult to blow off, and this operation will even be forced into the pores! In short, the car carbon filter after this operation basically loses the ability to filter air and block particles. Although it looks clean on the surface, it is just a kind of psychological comfort!
2. There was a test before, and it had three samples. New car carbon filter, 40,000-km car carbon filter, and 10,000-km mileage car carbon filter that have been cleaned by the blower. There is not much difference (slightly worse) in the filtering capacity of the filter, but the filter effect of the car carbon filter that was used for 10,000 kilometers but was blown by the blower was very poor.
To sum up, car carbon filter or jeep cabin filter is either replaced or left alone. The filtering effect of the old air filter covered with floating ash is also better than that of the air filter after cleaning. And car carbon filters are related to our health. After all, its quality is closely related to the air quality in the car. It is no problem to replace car filters frequently, and there is no harm in changing them in advance. The car carbon filter that works in a humid environment is too easy to breed bacteria and affect the body of the passengers in the car. Therefore, it is recommended to replace the air conditioner filter element more frequently, and the car carbon filter can be changed every 10,000 kilometers.
