Optimal Replacement Timing for Air Conditioning Filters

The function of the air filter is very simple. In short, it is a device that filters out particulate impurities in the air. Because the engine needs to inhale a lot of outside air when working, the “inhalable particles” in the air are filtered out through the filtering effect of the air filter, and then enter the (intake duct or) cylinder to mix with gasoline and burn. If the air filter does not play the proper filtering effect.

Then the larger particles in the air will enter the engine and burn, and various faults will occur overnight, among which the typical fault is cylinder pulling! Regarding the question of when to replace the air conditioning filter, different brands may get different answers. Some people suggest replacing it every 10,000 kilometers, and some people suggest replacing it every 20,000 kilometers!

In fact, the replacement of the air filter depends on the actual situation. For example, in some areas with strong wind and sand and a lot of dust, the master suggests that the owner should check the air filter every time he maintains it, and shorten the replacement cycle, and replace it once if necessary. In some cities with relatively clean air, the replacement cycle can be appropriately extended.

Many car owners will blow or flick the air filter when they check it and find it dirty. Is this reliable? Suggestion: If the air filter is not very dirty and has fine sand and dust, you can blow it out. However, if the air filter is very dirty and affects the subsequent use, it must be replaced!
