Open the hood and locate the air filter. Loosen the screws on the airbox to open it. Check the condition of the filter. If it is moldy or damaged, replace it with a new one and reinstall it.

I always change the cabin air filter on weekends. Open the glove compartment on the passenger side, gently press the clips on both sides to remove the entire glove box. Then you'll see a rectangular cover panel behind it—pinch the clip to open it. When pulling out the old filter, remember the arrow should face downward. Lightly tap the new filter to remove surface dust before inserting it with the arrow facing down. Close the cover and reinstall the glove box. The engine air filter is located in the engine bay—release the metal clip to lift the cover, remove the old filter and wipe any dust from the housing, then place the new one in smoothly and press the cover firmly. The whole process takes about ten minutes, requiring only a screwdriver as a tool. After replacement, you'll immediately notice fresher airflow. It's recommended to check these filters every 10,000 km or every six months.

I was quite nervous during my first filter replacement, so I specifically checked the vehicle manual to confirm the model. When replacing the cabin air filter, the engine must be turned off, and it's best to wear gloves to prevent scratches. Gently press open the glove box stopper as the plastic parts are prone to breaking. I noticed the filter slot often accumulates leaves, so I vacuumed it clean before installing the new filter, making sure the side with activated carbon faces the seat direction. Don't lose the screws from the air filter box and remember their positions when unscrewing. The new filter must be fully seated in the groove, and the box cover should click into place. After completion, start the engine to test the airflow; if there's any unusual noise, reopen and reinstall. While DIY replacement saves labor costs, it's advisable to watch a video tutorial for the first attempt.

Replacing the air filter is super easy: Open the engine hood, locate the black plastic square box, flip open the metal clips and lift the cover. After removing the old filter, wipe the box clean, insert the new filter smoothly, and snap the cover back on. The cabin air filter is behind the glove box - press the clips on both sides simultaneously to pull it out. The filter slot has a dust cover; remove it to take out the old filter. Pay attention to the arrow mark on the filter's side for correct orientation, and ensure the new one is fully pushed into place. I usually clean the AC drain outlet while at it, using a piece of wire to unclog the opening and prevent water accumulation. The whole process takes under 20 minutes. When buying filters online, make sure they match your vehicle model.

As a seven-year car owner, I've saved thousands in maintenance costs by changing the filters myself. The key is regularity: replace the air filter every time you change the oil, and always change the cabin air filter before the rainy season to prevent musty odors. When removing the glove box, avoid using excessive force—support the bottom to prevent it from dropping. For older cars, watch out for aging clips and keep some replacement clips on hand. Don’t skimp on filters by buying no-name brands; low-quality fibers can let dust through. After replacement, turn the AC to maximum airflow for two minutes before shutting it off to stabilize the filter’s position. Record the replacement date in your phone’s notes and have the technician check the installation during your next service.

Different methods for various cars: My SUV's cabin air filter is located above the accelerator pedal, requiring lying down to access it. Sedans often use cross-head screws to secure the air filter box, necessitating a special short-handle screwdriver. Japanese cars have hidden clips in the glove compartment, while American cars feature spring clips on the filter cover. Before starting, search for your car model + filter replacement video and watch it three times. When purchasing filters, pay attention to thickness specifications - ones that are too thick may not fit properly and could deform. Don't discard old filters carelessly; seal them in plastic bags to prevent dust dispersion. Additionally, inspect the AC ducts for cracks and address any damage promptly to prevent bacterial growth.
