Where is the Cabin Air Filter Located in a BMW 525?

The cabin air filter in a BMW 525 is located on the right side of the engine within the engine compartment. The functions of the cabin air filter are: 1. To provide fresh air; 2. To absorb harmful substances; 3. To filter solid impurities. Taking the 2021 BMW 525 as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 5106mm, width 1868mm, height 1500mm, a wheelbase of 3105mm, a fuel tank capacity of 68 liters, and a curb weight of 1705kg. The 2021 BMW 525 features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 184PS, a maximum power of 135kW, and a maximum torque of 290Nm, paired with an 8-speed automatic transmission.
As a long-time owner of a BMW 525, I clearly remember that the cabin air filter is located behind the glove compartment on the front passenger side. When replacing it, first gently release the clips on both sides of the glove box to remove it - be careful not to break anything by applying too much force. Then, you'll see a rectangular cover; use a screwdriver to remove three small screws, open the cover, and you'll find the air filter. I change it myself every 10,000 km or so. An OEM filter costs just a few dozen yuan, and the air feels much fresher afterward. It's quite simple to do it yourself - just wear a pair of dust-proof gloves for protection, and the only tools needed are a basic set of screwdrivers, saving you hundreds at the dealership. By the way, regularly changing the filter prevents odors in the car, improves AC efficiency, and is good for your health too.
From a car enthusiast's perspective, let me talk about the BMW 525's cabin air filter. It's usually hidden behind the glove compartment. You'll need to remove the glove box first, unscrew the clips, then remove the cover to take out the filter. Don't underestimate this component - it blocks dust and prevents odors, similar to the engine air filter but located differently. I've seen cases where aged filters restricted airflow, causing the AC to blow weakly while increasing fuel consumption. It's recommended to inspect it every year or 15,000 km, and when replacing, use a filter of the matching model available online or at auto shops. A quick tip: when removing the glove box, don't toss it around; place it on the ground to avoid scratches. After replacement, you'll notice improved AC performance and fresher cabin air.
