The air filter of the BMW 525li is located in the engine compartment, next to the engine hood support rod. Open the hood to see it. Here is more information about the air filter: 1. The air filter filters the air entering the cabin from the outside, improving air cleanliness. 2. The general filtering substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust, which can damage the air conditioning system and protect the health of passengers inside the car. It also prevents glass fogging. Extended content: The body dimensions of the BMW 525li are 5047mm in length, 1860mm in width, and 1491mm in height, with a wheelbase of 3108mm.
I think the air filter for the BMW 525Li is quite easy to locate—it's hidden behind the glove compartment on the passenger side. When you open the glove box, there's either a cover or a screw-fastened section. After unscrewing or prying open the cover, you'll find the filter inside. I’ve replaced it myself several times using basic tools like a screwdriver, and the process is pretty straightforward. It's recommended to replace the filter every two years or every 20,000 kilometers, especially if you often notice a dusty smell in the car or weaker airflow from the AC—these could be signs that the filter needs changing. Opting for an activated carbon filter is even better, as it helps eliminate odors and prevents allergies, which is great for health. When doing a DIY replacement, make sure the car is turned off and parked securely, wear gloves to protect your hands, and avoid using excessive force to prevent damaging the clips. After installing the new filter, you’ll immediately notice improved AC efficiency, fresher air, and even extended system lifespan with better fuel economy.
