Most vehicles have a **cabin filter** that helps clean the air entering the interior of the vehicle. This filter is important because street air can contain dirt and particles that, if not filtered, can affect the engine's performance and the air quality inside the vehicle.

- **Limited retention capacity:** Over time, the filter accumulates dirt and its ability to retain particles decreases. This means that the air passing through the filter may not be as clean as it should be, which can affect both the engine and the comfort of the vehicle's occupants.

- **Importance of replacement in spring:** At the beginning of spring, there is an increase in pollen and other particles in the air, which can saturate the filter more quickly. Replacing the filter at this time of year helps ensure that the air inside the vehicle remains clean and that the engine operates efficiently.

For these reasons, it is advisable to change the cabin filter, especially at the beginning of spring, to maintain its effectiveness and ensure a clean and healthy environment inside the vehicle.
