What is the purpose of a car's air conditioning filter?

[JuliaRose]

The function of the air conditioning filter: The air conditioning filter is installed at the engine's air intake, where it effectively filters out dust and impurities from the air, significantly increasing the purity of the air entering the combustion chamber, thereby ensuring complete fuel combustion. Below is some relevant information about air conditioning filters: 1. Air filters generally use paper filter elements, which can actually be cleaned and reused. 2. Cleaning precautions: Do not use water or oil for cleaning; instead, use the tapping method or the blowing method. The tapping method involves gently tapping the end face of the filter to dislodge dust. The blowing method involves using compressed air to blow the filter from the inside out. However, the number of times it can be cleaned is limited because, over time, its ability to filter air decreases. In such cases, the air filter should be replaced.
