The cabin air filter is installed in two locations: one is behind the glove box on the passenger side, and the other is on the lower right side of the windshield. The service life of the cabin air filter is 30,000 kilometers or one year. Regular cleaning of the cabin air filter can extend its service life. The cabin air filter is a filter installed in the car's air conditioning system that can absorb dust particles, reduce respiratory discomfort, minimize irritation for allergy sufferers, and protect the air conditioning cooling system. Functions of the cabin air filter: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air; 3. It absorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, and other substances from the air.

I found that the location of the cabin air filter is actually quite easy to locate. In most cars, it's hidden under the dashboard on the passenger side. If you open the glove compartment and remove it entirely—you might need to loosen a few clips or screws—you'll see a small rectangular box, which is the filter housing. My own car has this design, and I replace it once a year. Changing to a new filter before summer makes the air in the car especially fresh. If you don't replace it for a long time, dust buildup not only reduces airflow but can also lead to mold and unpleasant odors, affecting health. I recommend checking the manual regularly and replacing it approximately every 10,000 kilometers or every six months. Doing it yourself is simple; all you need is a screwdriver, and buying filters online is both cheap and convenient.

When doing DIY car repairs, the cabin air filter is usually within easy reach, located behind the glove box in 80% of vehicle models. I've replaced it several times: First, empty the glove box and press the clips on both sides or remove screws to take out the box; second, pull out the old filter housing, paying attention to the arrow markings to avoid installing it backward; third, insert the new filter and reassemble everything in place. The entire process takes less than 10 minutes, requiring only a Phillips screwdriver and a damp cloth to wipe off dust. For harder-to-access models, some are located under the hood near the windshield wiper cowl, but this is relatively rare. Regularly replacing it prevents bacterial growth, and it's recommended to check it every 8,000 kilometers.

The cabin air filter is usually located behind the glove compartment above the footwell on the passenger side. Incorrect positioning can lead to filtration failure, dust accumulation blocking the vents, and mold growth affecting air quality inside the car. I once experienced a situation where a clogged filter caused the AC to emit strange odors, which was very unpleasant. I recommend checking your owner's manual for the exact location or simply pulling open the glove box to peek inside. Don't extend replacement intervals too long - changing it every six months ensures healthy and safe operation.
