How often should car air conditioning filters and air filters be replaced?
2 Answers
Car air conditioning filters and air filters should be replaced as follows: 1. Car air conditioning filters should be replaced every three to six months; 2. Air filters should be replaced every year or every 10,000 kilometers. The air conditioning filter is installed near the air conditioning intake, behind the blower, and is used to filter the quality of indoor or outdoor intake air. The air filter refers to the engine intake system, which filters the quality of the intake air in the engine intake pipe. The air conditioning filter, also known as the cabin air filter, filters the air entering the vehicle cabin from the outside, improving air cleanliness, providing a good air environment for passengers inside the vehicle, and protecting the health of the vehicle occupants.
I've been driving for almost ten years and have gained quite some experience in replacing cabin air filters and engine air filters. The cabin air filter is mainly responsible for the air inside the car. I usually replace it every six months or 10,000 kilometers, especially when there's a musty smell from the AC or reduced airflow – that's definitely time for a change. The engine air filter is even more critical as it protects the engine's intake system. I typically inspect it every 10,000 to 15,000 kilometers. If I frequently drive on dusty roads or in areas with poor air quality, it might need replacement as early as 8,000 kilometers. I remember that time after driving through a sandstorm – when I opened the air filter compartment, it was completely filled with sand, so I immediately installed a new one. Never try to save money on these, especially if you have elderly or children at home. A dirty cabin air filter can easily trigger allergies. In humid climates, it's better to replace them earlier to prevent mold growth, which can be a real headache.
