Air conditioning filter VS air filter, do you know? How often do you change them?
Although the name is similar, the two are not different. Although the "air filter" and "air conditioning filter" both play the role of filtering air, and are replaceable filters, the functions are very different.
Air filter element
The air filter element of the car is unique to the internal combustion engine model, such as gasoline cars, diesel cars, hybrid vehicles, etc., its role is to filter the air needed when the engine is burning. When the car engine is working, fuel and air are mixed into the cylinder and burned to drive the vehicle. The air is purified and filtered by the air filter element, so the position of the air filter element is in the front end of the intake pipe in the automobile engine compartment. Pure electric cars have no air filter.
Under normal circumstances, the air filter can be replaced once half a year, and the high incidence of haze is replaced once every three months. Or you can check it every 5,000 kilometers: if it is not dirty, blow it with high pressure air; If it is obviously very dirty, it needs to be replaced in time. If the air filter element is not replaced for a long time, it will lead to poor filtration performance, and particulate pollutants in the air will enter the cylinder, resulting in carbon accumulation, resulting in decreased power and increased fuel consumption, which will shorten the engine life in the long run.
Air conditioner filter element
Because almost all household models have air conditioning systems, there will be air conditioning filters for both fuel and pure electric models. The function of the air conditioning filter element is to filter the air blown into the carriage from the outside world to provide a better driving environment for the occupants. When the car opens the air conditioning system, the air entering the carriage from the outside world is filtered through the air conditioning filter, which can effectively prevent sand or particles from entering the carriage.
Different models of air conditioning filter positions are different, there are two general installation positions: most models of air conditioning filter is located in the glove box in front of the passenger seat, the glove box can be seen; Some models of air conditioning filter under the front windshield, covered by a flow sink, the flow sink can be removed to see. However, very few vehicles are designed with two air conditioning filters, such as some Mercedes-Benz models, and another air conditioning filter is installed in the engine compartment, and two air conditioning filters work at the same time, the effect is better.
If conditions permit, it is recommended to check the air conditioning filter element every spring and autumn, if there is no odor and not too dirty, use a high-pressure air gun to blow it; In case of mildew or obvious soiling, replace it immediately. If it is not replaced for a long time, the dust is deposited on the air conditioning filter, and it is moldy and deteriorated in the humid air, and the car is prone to odor. And the air conditioning filter element absorbs a large number of impurities to lose the filtration effect, which leads to bacterial breeding and multiplication over time, which is harmful to the human body.
