What is the purpose of replacing the car air filter? There won't be anything too bad. Don't underestimate this small component. It is an important device responsible for cleaning up particulate debris in the air. The car air filter is an object used to clean the particulate matter in the air inside the car. The car air conditioning filter can effectively reduce the intake of air pollutants through the heating, ventilation and air conditioning systems, avoiding the inhalation of air pollutants that are harmful to the human body.

The function of car air filters

The air filter of a car is mainly a device responsible for cleaning particulate debris from the air. When piston-type machinery (such as internal combustion engines and reciprocating compressors) is in operation, if the air it sucks in contains dust and other impurities, it will accelerate the wear of components. Therefore, it is essential to be equipped with an air filter. The air filter is composed of two parts: the filter element and the casing. The specific standards for air filters are high filtration efficiency, low flow resistance, and the ability to be used continuously for a long time without maintenance.

Why do we need to replace the air filter in a car?

This also depends on the component it protects, that is, the car engine. It is a very delicate mechanical part. Even the tiniest debris can damage the car engine. Therefore, before the gas enters the cylinder, it must first pass through the fine filtration of the air filter before it can enter the cylinder. The air filter is the guardian of a car engine. The condition of the air filter is closely related to the service life of the car engine. If a dirty air filter is used in a car during operation, it will cause insufficient air intake to the engine, incomplete fuel combustion, and result in unstable engine operation, reduced power and increased fuel consumption. Therefore, it is essential to ensure that the air filter of a car is clean.

After reading the above, are you still wondering whether you should replace the car air filter or not? Leaving aside other impacts, just considering the fact that not changing the air filter for a long time can damage the car engine, is it more cost-effective to replace the air filter regularly or to have the car engine repaired or replaced when it breaks down? Of course, this does not take into account the issue of time. Therefore, it is more convenient and cost-effective for us to replace the car air filter regularly.

The replacement cycle of car air filters

This is not immutable. There are many conditions and restrictions. Under normal circumstances, it is proposed that customers replace it every 15,000 kilometers of driving. However, for vehicles that frequently operate in extreme natural environments (such as deserts and construction sites), they should be replaced no more than once every 10,000 kilometers. Sedans need to be replaced every 30,000 kilometers, while business vehicles need to be replaced every 80,000 kilometers. Of course, this is only under normal circumstances. The specific replacement cycle also depends on the quality of the air filter selected. The air filters in the Yisun smart accessories cabinet are of relatively good quality. They are all products from the well-known brand Kaka Mai and are of guaranteed quality.
