There is a very important reason why car owners like to ask how often does car ac cabin filter change. That is, you can't know whether cars will be "uncomfortable" because of your own negligence. Therefore, out of a sense of anxiety about the unknown, car owners are very concerned about the replacement cycle of the wearing parts. Car ac cabin filter can be regarded as a "wonderful" existence in the car's wearing parts, because this thing is not for the car, but for the people. In other words, whether to change it or not, no one has a say as you do.
We all know that the role of car ac cabin filter is to filter the air blown out by the air conditioner. It is a same concept with the filter of our home air conditioner. Regardless of whether the internal circulation or the external circulation is used, the air inside and outside the car must be filtered before it can be blown out from the air outlet. So the question is, while the total amount of filterable material of a filter is certain, how to calculate its service life? This depends on the quality of the ambient air. If the air quality is good, it will take a long time for the filter to reach the saturation of the filter; if the air quality is poor, the filter will soon become full of dirt and fail. .
Because the same model will be sold in different regions, the air quality and car owners' habits vary greatly, but the maintenance manuals that the car owners get are the same, so the above unified standards must be problematic. In addition, there are many different kinds of car ac cabin filters, such as BMW cabin air filter, Audi cabin air filter and Toyota aircon filter. Now everyone should understand why the cycle given in the maintenance manual is inaccurate. Imagine that there are two cars: one is driving in the sandstorm all day, and the driver is a big-footed man who often smokes cigars in the car; the other has been used in northern Europe with pure air, and the driver is a beautiful woman who does not smoke. Can the air-conditioning filter replacement cycle of the two cars be the same?
Please note that what is said here is "relatively reasonable", because absolute rigor cannot be done, unless you can use a professional microscope to observe the number of microorganisms and harmful particles on the filter paper. Owners who work in the microbiology laboratory can give it a try. For ordinary car owners, we only need to use three rough methods:
1. Smell with nose
If you feel that you can smell the smell every time you turn on the air conditioner, then you can consider replacing the filter. Car ac cabin filter is meant to serve people. Now that your nose is protesting, you can replace the car ac cabin filter.
2. Touch it by hand
Feel the air volume at the air outlet of the air conditioner by hand. If you hear the blower whirring, but the air volume is much smaller than before, it is very likely that the car ac cabin filter is blocked by dirt. At this time, it is also recommended to replace it, after all, a small air output will also affect the effect of the air conditioner.
3. Look with your eyes
Take down the car ac cabin filter and take a look at how many dirty things are on it, such as leaves, corpses, wool, dust, and even dead mice. Then imagine for yourself that all the air blowing into the car has to touch these things. If you feel sick, get a new one quickly.
