I remember once my BMW 330i's AC had a strange odor, so I decided to replace the filter myself. It's located on the passenger side, above the footwell area, roughly near the bottom of the glove compartment. Bend down and lift that thick soundproofing foam cover, and you'll see a small housing where the filter sits. Be careful when removing it – don't apply too much force or you might break the small clips. I'd recommend watching a year-specific video tutorial since designs vary slightly between models. After replacement, the air became much fresher, especially during spring when there's lots of pollen – it filters out many impurities. For safety, disconnect the battery negative terminal before starting to prevent accidental short circuits. The location is somewhat hidden, but once you're familiar with it, the next time will be much quicker, and you can save some money on dealership inspections.

I learned about the location of the BMW 3 Series' cabin air filter from a friend, who said it's under the passenger seat. Later, I checked the owner's manual and confirmed it's in the footwell area, covered by a soft pad. I tried replacing it myself but found the space too tight—it's hard to even get my hand in there. Messing up the wiring would just add more trouble. I recommend taking it directly to a professional repair shop. The technicians know their way around and can get it done in minutes, plus they'll check the system's sealing. A dirty filter affects respiratory health, especially during long drives when there's more dust. Don't risk it to save a few bucks—regular replacement is good for the car's lifespan too. Generally, once a year is the most suitable interval.
