How often should the car's air filter be replaced?

According to the car's maintenance manual, it should be replaced every 10,000-20,000 kilometers or once a year. It is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The location of the car's air filter element is determined by the intake form and the engine structure, and it is generally located in the air filter on the engine intake pipe. There are two types of air filters in cars: dry and wet. The dry type is made of paper or organic materials, while the wet type is made of metal wire mesh. The function of the air filter: to filter out particulate impurities in the air, ensure that sufficient clean air enters the cylinder, and prevent floating dust in the air from being sucked into the engine, which accelerates the wear of the piston group and cylinder. Air filter: It is a type of filter, also called an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand in the air, ensuring that sufficient and clean air enters the cylinder. Using a dirty air filter in a car will cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several clean air filter components. Its main function is to filter out harmful impurities in the air that is about to enter the cylinder, to reduce early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When checking the air filter, if it is found to have little dust and is lightly clogged, it can be cleaned with high-pressure air from the inside out and continue to be used. A heavily dirty air filter should be replaced promptly.
I've been driving for almost ten years, and the frequency of changing the air filter really depends on the specific situation. Generally, it's recommended to replace it every 10,000 to 15,000 kilometers or once a year, but this is just a starting point. If I mostly drive in the city where the air is cleaner, I might stretch it to a year and a half. But if I work in dusty rural areas with constant wind and sand, the filter gets clogged faster and might need checking every six months. I have an old car myself, and when the filter gets dirty, the engine sound becomes muffled, acceleration slows down, and fuel consumption can increase. Replacing it early not only saves fuel but also protects the engine's lifespan. My neighbor procrastinated on changing it and ended up spending a fortune on engine repairs. Actually, checking it yourself is easy—just pop the hood, and the filter box is right there; see if it's covered in black dust. Remember, don't skimp on this small expense. Regular maintenance ensures a smooth and enjoyable ride.
As a working professional who drives frequently, I prioritize environmental protection and car maintenance efficiency. How often should the air filter be replaced? Roughly once a year or every 10,000 kilometers, but environmental factors must be considered. If you live in a city with heavy smog or near construction sites, the air is dirty and the filter clogs faster, becoming filthy in just three to four months. Replacing it early helps the engine breathe better. I’ve tried being lazy with replacements, and fuel consumption increased by over 5%, wasting money. Regularly changing the filter improves air quality, protects the environment, and reduces emissions. Simple maintenance: every three months, take a moment to check the filter’s color. If it’s dirty, clean it with compressed air; if it’s beyond cleaning, replace it. The fuel savings can cover the cost of a new filter, allowing for more long-distance trips and a greener, safer lifestyle.
