S90's cabin air filter is located inside the glove compartment on the passenger side. Below is relevant information about the cabin air filter: Function of the car's cabin air filter: It filters the air entering the cabin from outside to improve air cleanliness. The filtered substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust. The purpose of the cabin air filter is to prevent these substances from entering the air conditioning system, thereby protecting the system, providing a good air environment for passengers, safeguarding their health, and preventing window fogging. Replacement interval for the cabin air filter: It is recommended to replace the car's cabin air filter once a year. Otherwise, after prolonged use, the filter can become extremely dirty, severely affecting the air conditioning's performance and potentially leading to mold growth and unpleasant odors.

To answer your question about the location of the S90's cabin air filter, I've changed it several times in my own car, so I'm quite familiar with its hiding spot behind the glove box. When you sit in the passenger seat, empty the contents of the glove box, then gently press the clips on the sides of the compartment to release it. You'll then see a rectangular cover—open it, and the cabin air filter is right there. Volvo designed it in this location to make DIY replacement easier for users, as the cabin air filter is crucial for blocking dust and pollen, protecting the air quality inside the car, especially for those with allergies or children. I recommend replacing the filter every 12 months or after driving 15,000 kilometers. This not only keeps the cabin air fresh but also improves the efficiency of the air conditioning system. If you're unsure about doing it for the first time, you can check out YouTube tutorials, but remember not to use excessive force to avoid damaging the plastic components.

Based on my understanding of models, the cabin air filter for the S90 is located under the dashboard on the front passenger side, specifically behind the glove box. After removing the glove box, you'll find a box with a handle—simply pull it gently to remove the old filter and insert the new one. When selecting a filter, you can use either an OEM part or a compatible brand, with prices ranging from tens to a hundred yuan. The advantage of this design is that it makes replacement quick and easy, but if you're unfamiliar with car structures, it's best to visit a 4S shop or auto repair shop and have a professional handle it to avoid damaging the wiring. Regularly replacing the filter can reduce odors and bacterial growth, protecting your health and making long drives more comfortable.

Replacing it too infrequently can lead to odors from the air vents or reduced cooling efficiency. It's recommended to check the filter every 10,000 kilometers or at least once a year to prevent minor issues from escalating. If it feels troublesome, spending a little money to have a professional handle it is also safer.
