How often should car air conditioning filters and air filters be replaced?

[VanAlexandra]

The replacement cycle indicated in the vehicle maintenance manual suggests that the air filter should generally be replaced every 20,000 to 60,000 kilometers. If the driving mileage is low, it is recommended to replace it every 12 months. The air conditioning filter should be replaced approximately every 10,000 kilometers. If it is not replaced for a long time, it will affect the performance of the air conditioning and the health of the passengers. Air conditioning filter: The car's air conditioning filter is a crucial component of the air conditioning system. Its main function is to filter bacteria, PM2.5, moisture, pollen, dust, and other particles from the air. It is recommended to inspect both the air and air conditioning filters during every maintenance service. The car's air filter location varies depending on the intake design and engine structure, but it is typically located in the air filter housing on the engine intake pipe. The air conditioning filter is usually installed under or inside the glove compartment on the passenger side, though in some models, it may be located under the windshield in front of the passenger seat. Function of the air conditioning filter: It absorbs fine particles, reduces respiratory discomfort, minimizes irritation for allergy sufferers, and protects the air conditioning cooling system. Without the air conditioning filter, these particles could enter the cabin, contaminating the air conditioning system, reducing cooling efficiency, and causing health issues such as allergic reactions, lung damage, and irritation from ozone exposure, all of which can affect driving safety. Dirty air conditioning filter: If the car's air conditioning filter becomes dirty, it can clog with impurities, reducing airflow and affecting the cooling performance. This can also increase fuel consumption, generate noise, and shorten the lifespan of the air conditioning system. Residual impurities on the filter can breed bacteria and mold, posing health risks to passengers and potentially leading to serious illnesses. Air filter: Also known as an air cartridge, air cleaner, or air element, it is a type of filter used in engineering vehicles, cars, agricultural machinery, laboratories, sterile operating rooms, and other precision environments. Function of the air filter: It filters particulate impurities from the air, ensuring sufficient clean air enters the cylinders and preventing airborne dust from being drawn into the engine, which could accelerate wear on piston assemblies and cylinders. Dirty air filter: Using an excessively dirty air filter while driving can restrict engine airflow, leading to incomplete fuel combustion. This results in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean or replace it promptly.
