The cabin air filter in the BMW 730 is located under the wipers in the engine compartment. The cabin air filter is a component installed in the vehicle's air conditioning system that absorbs dust particles, alleviates respiratory discomfort, reduces irritation for allergy sufferers, and protects the air conditioning cooling system. The BMW 730 is a full-size luxury sedan with dimensions of 5273mm in length, 1902mm in width, and 1498mm in height, with a wheelbase of 3210mm. This vehicle features a 4-door, 5-seat sedan body style, an 8-speed automatic transmission, turbocharged intake, rear-wheel drive configuration, electric power steering, and a unibody structure.

On the BMW 730, the cabin air filter is typically located behind the glove compartment on the passenger side. First, open the glove compartment door and check if there's a cover secured by clips or screws on the inner wall. Gently remove the cover to access the filter. Having driven several generations of the BMW 7 Series, I can confirm the location remains fairly consistent, making DIY replacement quite convenient—just prepare a new filter purchased by model number (online prices hover around a hundred yuan). Ensure the engine is off during the process to avoid accidental electrical damage. Post-replacement, air quality improves noticeably, eliminating stuffiness and providing fresher airflow. BMW's user-friendly design makes this a 10-minute job—no need to overpay at dealerships. DIY saves money while honing skills, plus it simplifies maintenance records. Remember to inspect every six months; urban driving accumulates dust quickly, clogging filters and impairing cooling efficiency.

As a young person who often drives a BMW, I found that the cabin air filter of the 730 is hidden behind the glove box, and the removal process is super simple. First, empty the glove box of any items. There are two plastic clips on the sides—pinch them inward to release the entire glove box door. Once removed, the filter cover is exposed; just pry it open with a screwdriver to pull out the old filter and replace it with a new one. I just changed mine last month, and a filter like the CUK2739 model will do the trick—just a few dozen RMB on Taobao. Notice strange odors when the AC is on high during highway driving? It’s likely due to an aging filter. Don’t wait until the sweltering summer to think about maintenance; pay attention to airflow changes from the vents during regular driving. Here’s a small tip: while replacing the filter, take the chance to clean out dust and debris inside the glove box—keeping the car tidy makes driving more pleasant. Regular maintenance extends the AC’s lifespan, saving you hassle, fuel, and even being eco-friendly.

The BMW 730 features a well-equipped air conditioning system, with the cabin air filter conveniently located behind the glove compartment on the passenger side. Simple steps: Open the glove box door, locate and release the internal clips to remove the cover panel, then directly replace the filter. It's crucial to select the correct activated carbon filter model for optimal filtration performance. The system's efficiency relies on proper airflow - a clogged filter not only reduces cooling effectiveness but also increases fuel consumption. I recommend consulting the owner's manual to verify the exact location or searching online for disassembly video references. As a general rule, inspect the filter every 10,000 kilometers to prevent odor buildup. For older vehicles, pay special attention to potential seal aging in the filter housing that may cause dust leakage. This minor maintenance task significantly impacts driving health - never overlook it.
