Where is the cabin air filter located in a Jetta?

The cabin air filter in a Volkswagen Jetta is located at the lower left side of the front passenger seat. Below are the functions of the cabin air filter: 1. It helps filter out fine impurities and dust inside the vehicle, providing a more comfortable and superior cabin environment. During engine operation, a large amount of outside air is required, which inevitably draws in impurities. The cabin air filter removes these impurities and microorganisms from the air. 2. The recommended maintenance interval for the cabin air filter is every 20,000 kilometers or once a year. If the vehicle is frequently used in areas with severe smog, it is advisable to replace the filter more frequently as needed. Using an original activated carbon filter from the manufacturer can provide better results. It is also recommended to replace the cabin air filter at the start of spring and autumn each year to coincide with seasonal changes.
I've been driving my Jetta for many years and always change the cabin air filter myself. The location is very clear - right behind the glove compartment on the passenger side. Removing the glove box is easy, just pinch the clips on both sides and pull it down. Then you'll see a plastic cover, open it to pull out the old filter. When replacing, pay special attention to the arrow direction - align it properly before inserting the new filter. My Jetta runs over 20,000 kilometers a year, so I change the filter every six months without fail, otherwise the air blows out full of dust. Especially before and after the southern rainy season when mold grows most easily. Spending a dozen yuan on a good activated carbon filter can both filter dust and absorb odors. Changing it before using the AC in summer makes the air much fresher.
