[YesAuto Use Car Collection] Due to the epidemic and smog, masks have become a must-have item in daily life. Air purifiers large and small are now selling hotly, and everyone is paying more and more attention to the air quality in living areas. But many people have neglected whether the air quality in our cars meets the standards. For the health of everyone, I decided to teach you the DIY method of replacing the filter element that I practiced hard for 1 minute, so that we can get rid of the shackles of masks in the car and “breathe freely” with our mouths open.
This article takes Audi A6L (C7) as an example. Before we start to replace it, we need to pay attention to several points:
1. Ensure that the vehicle is parked, tighten the handbrake and turn off the engine.
2. Try to wear gloves to operate.
3. Pay attention to the appropriate force when screwing the screws and pulling out the clips.
4. The style of the filter element is different for different models, so you must choose a filter element that matches your own model to replace it.
5. Under normal circumstances, replacing the air filter and air conditioning filter by yourself will not affect the warranty, but individual brands may have restrictions in this regard. Please understand the brand's policy before you replace it.
●The role of the air filter:
The function of the air filter element is mainly to provide clean air for the engine. Because the engine needs to inhale a large amount of air when it is working, if it is not filtered, the dust in the air will be directly sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Broken, greatly reducing the service life of the engine. If larger particles enter between the piston and the cylinder, it will damage the inside of the engine. In severe cases, it will cause “cylinder pull”. The existence of the air filter is to help the engine filter out the impurities in the air and ensure clean air entering the cylinder.
●The replacement cycle of the air filter:
In fact, the air filter element does not have a more accurate replacement cycle. Generally, it is 10,000 kilometers or about 1 year, but it depends on our actual usage. If the air quality in our area is poor, it is recommended You can check the air filter regularly and shorten the replacement cycle.
● Replacement of air filter element:
The car air filter is in the engine compartment. Although there are differences in design between brands, the positions are roughly the same, and they are generally near the vehicle engine. We can check the maintenance manual of the vehicle before replacement, so that we can find its location more clearly.
It is recommended that you check the air filter element regularly according to the actual usage, because if it is not replaced for a long time, not only the filtering effect will be affected, but if the filter element is too dirty, it will also affect the air intake of the engine.
●The role of air conditioning filter:
The function of the air conditioning filter is roughly the same as that of the air filter. When we drive with the air conditioner, we need to inhale outside air into the car, but the air contains many different particles, such as dust, pollen, soot, abrasive particles, ozone, peculiar smell, Nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. The air conditioner filter can effectively help us filter out the impurities in the air and ensure that the air entering the car is clean.
● The replacement cycle of air-conditioning filter element:
The replacement cycle of the air conditioning filter element and the air filter element is roughly the same. Basically, they are replaced every 1 year, or 10,000 to 10,000 kilometers. There are more ways to determine whether the air conditioning filter element needs to be replaced. The first is that the air output of the air conditioner is compared with the previous one. Is it significantly smaller, the second is whether there is a peculiar smell from the air outlet, and the third is the use time of our filter element. Of course, the above three situations are only ways to assist us in judging whether the filter element should be replaced, and we need to consider the actual use situation and the air quality of the city to determine the replacement time.

In fact, replacing the filter element by yourself is a very simple matter. Not only can you save money, but we can also choose high-quality brand filter products. Of course, if the 4S shop of the brand where your model belongs to replace the filter element for free during maintenance, it is another matter, but it is definitely a good thing to master a new skill. Don’t check the filter element of your car while you are hot. . (Part of the picture comes from the network article/Car Home Zhao Xiang)
