Old model BMW 730 cabin air filters are located under the wipers in the engine compartment; new model BMW 730 cabin air filters are placed inside the glove compartment on the passenger side. The functions and types of cabin air filters are as follows: Cabin air filter functions: The cabin air filter supplies fresh air to the passenger compartment, effectively separating solid impurities such as dust, pollen, and grinding particles from the air, ensuring that drivers and passengers do not experience allergic reactions that could affect driving safety. Cabin air filter types: Based on filtration principles, air filters can be divided into several types: filtration type, centrifugal type, oil bath type, and composite type.
The cabin air filter on the BMW 730 is located behind the glove compartment on the passenger side. I've driven this model before and changed it several times myself. Open the glove box door, and you'll find a small cover inside. Remove a few clips with a screwdriver to access the filter. The placement is quite logical since the air intake for the AC is above the passenger footwell, allowing the filter to directly intercept dust and debris. Be careful not to use excessive force to avoid damaging the plastic components. The cabin air filter tends to get dirty quickly, especially with frequent driving or in dusty areas. If you notice reduced airflow or unpleasant odors, it's time for a replacement. I typically check it every two years or after driving 15,000 kilometers to maintain fresh air quality, which is better for respiratory health. The replacement process takes only about 10-15 minutes, and buying parts online can save you a significant amount of money.
I've been driving a BMW 730 for some time, and the cabin air filter is typically located in the footwell area on the passenger side, specifically behind the glove compartment. You'll need to remove the glove compartment door first, usually by unscrewing a few screws, then locate a small panel—once opened, the filter will be exposed. When replacing it, be careful not to damage the clips; simple tools like a screwdriver will suffice. The filter significantly impacts AC performance. If left unchanged for too long, the air inside the car may feel stuffy or develop odd odors, potentially triggering allergies. I recommend replacing it every 1-2 years, adjusting based on driving conditions and seasons—for instance, more frequently in dusty areas or during intense heat. The location makes it easy to maintain, and even beginners can attempt a DIY replacement. However, if unsure, it's best to visit a professional shop—they can get it done in about ten minutes while also performing a full vehicle inspection.
