How Often Should the Car Air Conditioning Filter Be Replaced?
2 Answers
Car air conditioning filters should be replaced approximately every 10,000 kilometers. The method for replacing the air conditioning filter is as follows: 1. Remove the damping rods on both sides of the glove box; 2. Take off the glove box to reveal a black rectangular cover plate, pry it open, and remove the clips; 3. Take out the old air conditioning filter; 4. Install the new filter. The functions of the air conditioning filter include: 1. Providing fresh air; 2. Ensuring safety and hygiene; 3. Absorbing harmful substances; 4. Filtering solid impurities. The method for using the air conditioning system is: 1. Turn on the AC switch; 2. Adjust the air outlet selection knob—direct the air outlet upward when cooling and downward when heating; 3. Adjust the fan speed switch; 4. Adjust the air recirculation conversion knob; 5. Adjust the temperature control knob.
After 10 years of car maintenance, I've learned that you can't rigidly stick to the recommended intervals for cabin air filter replacement. As a city commuter running the AC at full blast during summer rush hours, I need to change mine every six months. Last week, I was shocked when I opened the filter – completely clogged with leaves and dead insects! For those frequently driving through construction sites or heavily polluted areas, inspection every three months is necessary. Nowadays, activated carbon filters on Taobao cost just 30 yuan, and DIY replacement takes only 10 minutes, saving over 200 yuan compared to dealership service. Here's a pro tip: if you notice a musty smell or reduced airflow when using the AC, immediately check the filter behind the glove compartment – if it feels stiff or looks blackened, it's time for a replacement.
