Replacing the air filter involves the following steps: 1. Open the engine hood; 2. Remove the air filter element; 3. Thoroughly clean the air filter box; 4. Install the prepared air filter. The functions of the air filter are: 1. To ensure the air filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. To separate dust, pollen, and solid particles from the air; 3. To absorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2 from the air, providing strong and lasting moisture absorption; 4. To prevent car windows from fogging up, ensuring clear visibility for the driver and safe driving; 5. To maintain clean air in the passenger compartment and prevent bacterial growth.
I just helped my neighbor replace the air filter last week. Open the hood and locate that black plastic square box, usually near the engine. Use a screwdriver to loosen the fixing screws, or gently pry open for models with clips. Don't rush to throw away the old filter when removing it - check how much dust and leaves are clogged on it first, as this helps determine the next replacement time. Cleaning sand particles in the filter box is crucial; last time I found a thick layer of sand accumulated at the bottom. When installing the new filter, pay attention to align the arrow direction with the airflow direction - installing it backwards affects filtration efficiency. Finally, close the box tightly and start the engine to listen if the intake sound is smooth. The whole process takes about 20-30 minutes. Beginners are advised to prepare a 10mm socket and gloves.
