How many kilometers should the air conditioning filter of a truck be replaced?

Truck air conditioning filters should be replaced every 15,000 kilometers. The specific replacement cycle depends on the vehicle's usage conditions and driving environment. During cold weather, the requirements for air filters and diesel filters are higher, and the filter must be replaced no later than 15,000 kilometers; otherwise, it may affect the vehicle's lifespan. The air conditioning filter is a device that removes particulate impurities from the air. Its functions include: 1. Ensuring the filter fits tightly against the housing to prevent unfiltered air from entering the cabin; 2. Separating dust, pollen, and solid particles from the air; 3. Preventing car windows from fogging up, ensuring clear visibility for drivers and passengers; 4. Maintaining clean air in the cabin and preventing bacterial growth.
As a long-haul truck driver, I have to say that the replacement of the air conditioning filter depends on the specific situation. Generally, it is recommended to replace it every 15,000 to 20,000 kilometers. However, if you frequently drive on dusty or construction roads, it's best to check it every 10,000 kilometers. I learned my lesson the hard way when I delayed replacing the filter to save money. The air vents started emitting a strong odor, the air inside the cabin became polluted, and prolonged driving made my eyes itch. A clogged filter can reduce the cooling efficiency of the air conditioning, making it hard to feel cool air in the summer, and it can also lead to bacterial growth, which is harmful to health. For city driving, the frequency can be lower, but for long-distance transportation, regular checks are essential. I always make sure to replace it before summer every year, so I can drive with peace of mind.
Having worked in the repair shop for many years, I often see issues with truck air conditioning filters. There's no uniform standard for replacement intervals. It's best to check every 10,000 to 12,000 kilometers and replace immediately if dirty. The filter acts like a mask, blocking dust and pollen. If clogged, it restricts airflow, reduces AC airflow, and can even damage the blower motor. In practice, it's simple: usually located below the glove compartment, just remove the old filter to check dust accumulation. For frequent use in polluted areas like coal or construction waste transport, consider shortening the interval to 8,000 kilometers. DIY replacement is low-cost, while shop replacement only costs around 100-200 yuan. Neglecting it accelerates AC system aging, making expensive repairs even less worthwhile.
I believe the cabin air filter is crucial for health. The air inside trucks can be unclean, and a dirty filter may allow allergens or bacteria to enter. It's recommended to replace it every 12,000 to 15,000 kilometers. For those who frequently take long-distance trips, regular replacement can help reduce coughing or rhinitis.
