Air filter VS air conditioning filter, do you really know the difference？

　　"You need to change this air filter."　

　　-Technicians often remind you to change the air filter.

　　But can you really tell the difference between two kinds of "air filtration"?

　　Both air filter and air conditioner filter filter air. What’s the difference between them? Today, Xiaobian will give you a detailed explanation.

　　First of all, focus! Remember clearly:Air filter is to filter the air entering the engine, while air conditioner filter is to filter the air entering the cab.

　　A protective engine,

　　A protector!

　　Although they have different positions, different functions and different replacement cycles,But they are equally important.

　　Location:　Open the front hood of the vehicle, usually around the engine (different models and different directions). Just open the fixing screw on the air filter box with a screwdriver and you can see the air filter element.

　　Function:　The air entering the engine cylinder is carefully filtered to ensure that sufficient and clean air enters the cylinder. Whether it can be kept clean and unobstructed is related to the life of the engine.

　　Replacement cycle:　Under normal circumstances, the vehicle should be replaced once every 10,000 kilometers or about half a year, and it is best to replace it once every three months when the fog or catkins are serious.

　　Harm of not replacing in time:　If the replacement cycle is exceeded, the filtering performance of the air filter element will deteriorate, and the particulate pollutants in the air will directly enter the cylinder, which will easily produce carbon deposition, leading to a decrease in power and an increase in fuel consumption, which will shorten the life of the engine for a long time.

　　Location:　Open the storage box of the co-pilot of the vehicle and take off the baffle to find the air conditioning filter. (except for a few models. )

　　Function:　Filtering the air that enters the interior of the carriage from the outside can improve the cleanliness of the air (filtered substances refer to impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and dust, etc.), which can provide a good air environment for people in the car and protect their health.

　　Replacement cycle:　Under normal circumstances, it is recommended to replace it once every six months, or it can be decided according to the external environment of driving. When air conditioners are often used in winter and summer or during the period of high smog, the replacement cycle can be shortened appropriately.

　　Harm of not replacing in time:　If the replacement cycle is exceeded, the air conditioning filter element will lose its filtering effect if it absorbs a large amount of impurities, which will lead to the breeding and reproduction of bacteria over time, seriously affecting the health of passengers in the car.

　　Seeing this, riders should be able to easily distinguish between air filter and air conditioning filter! Of course, they are so important that their maintenance or purchase can not be ignored.

　　At present, air pollution in many cities in China is serious, and air filters and air-conditioning filters are prone to blockage, which is harmful to health, so we must pay attention to cleaning or replacing them in time.

　　How to judge whether the air filter should be changed?

　　1. First of all, we must observe and carefully look at the air filter itself, whether it is dark or black. If the air filter is obviously black, then at this time, this air filter should be replaced.

　　2. Generally, the air filter that is about to break will be deflated. If it is found, it needs to be replaced.

　　3. The third point is maintenance. If there is a lot of dust around the air filter, then we need to clean it at this time. If the effect of the filter is still not good after cleaning, please replace it in time.

　　How to judge whether the air conditioning filter should be replaced?

　　1. If the air conditioner has been turned on to the maximum gear, but the air output for cooling or heating is still very small, if the air conditioning system is normal, the reason may be that the air conditioning filter used has poor ventilation effect, or the air conditioning filter has been used for too long, so it should be replaced in time;

　　2. If the air blown by the air conditioner is smelly, the reason may be that the air conditioning system has not been used for a long time, and the internal system and air conditioning filter are caused by damp and mildew. It is recommended to clean the air conditioning system and replace the air conditioning filter.

　　Xiaobian reminder: For the health of yourself and your family, remember to clean and maintain it in time ~
