Where is the cabin air filter located in a 2013 BMW 525?

BMW 525 cabin air filter is located in the engine compartment. Here are the relevant details: 1. Function: The primary role of the cabin air filter is to filter out dust, bacteria and other particles from incoming air, keeping the cabin air fresh. This ensures passenger comfort during driving while protecting occupants' health. 2. Risks: Without filtration, these particles would enter the cabin, contaminating the AC system and reducing cooling performance. Inhaled dust and harmful gases may cause allergic reactions, lung damage, ozone-induced irritability, and unpleasant odors - all compromising driving safety.
For the 2013 BMW 525, the cabin air filter is located in the footwell area in front of the front passenger seat, specifically behind a removable panel beneath the glove compartment. Let me briefly share my experience, as I've replaced it several times. You'll need to first open the front passenger door, crouch down to inspect the footwell area where there's a rectangular plastic cover secured with screws. After unscrewing and gently lifting the panel, you'll see a square-shaped filter housing—simply pull it out. The job isn't particularly difficult, but I recommend wearing gloves to avoid dirty hands. I suggest checking or replacing it annually, especially in cities with heavy air pollution, as a dirty filter worsens cabin air quality and can even cause sneezing on long drives. DIY replacement saves money, and online tutorials are available for reference—just be careful not to force and damage the clips.
