空气滤芯使受到污染的空气被洁净到生产、生活所需要的状态，也就是使空气达到一定的洁净度。

The filter element separates solid particles in liquid or gas, or allows different substance components to come into full contact, accelerating reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain specification of filter, its impurities are blocked, and the clean fluid flows out through the filter element. The liquid filter element enables the liquid (including oil, water, etc.) to be cleaned to the required state for production and daily life, which is to achieve a certain degree of cleanliness of the liquid.

The air filter enables the polluted air to be cleaned to the state required for production and daily life, which means that the air reaches a certain level of cleanliness.
