How often do air filters and air conditioning filters change? Can you blow on it and continue to use it?
Air filter element and air conditioning filter element are the normal maintenance and replacement parts of the car. Normally, the air filter element can be maintained and replaced once every 10,000 kilometers. The general 4S shop requires that the air conditioning filter element be replaced at 10,000 kilometers, but in fact it can be replaced at 20,000 kilometers.
The air filter element is the mask of the engine. Normally, the engine intake must be filtered. Because there are many impurities in the air, sand particles are also common. According to experimental monitoring, the wear difference between the engine with air filter element and without air filter element is about eight times, therefore, the air filter element must be replaced regularly.
