The cabin air filter in a BMW 320i is located inside the glove compartment on the passenger side. Below are the steps for replacing the cabin air filter: 1. Open the glove compartment and remove the fuse box cover. 2. Detach the spring cord buckle, then forcefully pull upward to remove the plastic crossbeam above the glove compartment. 3. Squeeze both sides toward the center to completely remove the glove compartment, exposing the cabin air filter housing. 4. Unclip the buckles on both sides to open the housing cover, then remove the old filter and install the new one before reassembling in reverse order. Below are the functions of the cabin air filter: It minimizes the entry of unfiltered air into the vehicle cabin. It filters out solid impurities such as dust, pollen, and abrasive particles from the air, while also absorbing harmful substances and moisture. Additionally, it ensures clean air in the passenger compartment and prevents bacterial growth.
I've replaced the cabin air filter on my BMW 320i before. The thing is actually located inside the glove compartment on the passenger side. After removing the glove box rear cover, you can see the filter housing - it's not too deep and quite easy to locate. During replacement, you can use a screwdriver or just hand strength to twist open the clips, pull out the old filter and insert the new one (just make sure not to install it backwards). I remember being a bit clumsy the first time, but it became much quicker after getting familiar with the process - saves me the trouble of visiting repair shops every time. The filter should ideally be replaced every year or 20,000 km, especially in dusty urban areas. Delayed replacement can lead to reduced airflow and unpleasant odors - I noticed significantly fresher air after my last replacement. The DIY cost is just a few dozen RMB, plus it extends the AC system's lifespan. Why wouldn't you do it?
I used the air conditioning filter in my BMW 320i for several years. To replace it, you need to remove the inner cover behind the glove box to access the slot. When pulling out the old filter and installing the new one, paying attention to the direction is crucial—otherwise, the filtration efficiency will be poor, affecting the air quality inside the car. I believe regular replacement can reduce bacterial growth, and checking before the rainy season helps prevent odor issues. Choose a filter of the right size—don’t skimp on cost, or you’ll end up losing more than you gain. The design of the location makes DIY feasible without professional tools; it can be done in just a few minutes, saving money and providing peace of mind.
