2 Answers
BMW 320's cabin air filter is located behind the glove compartment on the passenger side. Below are the steps to locate the BMW 320 cabin air filter: 1. First, remove the floor mat. 2. Locate the upper part of the footwell and use tools to remove the partition panel. 3. After removing the panel, you will see the air conditioning ducts. Use a screwdriver to open the plastic layer of the air conditioning ducts. 4. Once opened, you will find the filter. Here is some information about automotive filters: 1. A typical gasoline-powered passenger car generally has four filters. 2. For the engine, there is an oil filter to filter engine oil; an air filter to filter combustion air; and a fuel filter to filter gasoline. 3. Only the cabin air filter, also known as the interior filter, is responsible for filtering the air inside the vehicle cabin.
I've driven several BMW 3 Series cars and found that the cabin air filter is usually located in the footwell on the passenger side or behind the glove box. Open the glove box, and you might see a small cover—just unscrew or unclip it to access the filter. DIY replacement is really convenient. Last time I changed it, the new filter cost me less than 100 yuan, and all I needed was a screwdriver. The key is to replace it regularly and not delay too long. A clogged filter reduces airflow from the AC and can cause bad odors or even allergies, especially on long drives. Personally, I replace mine once a year or every 15,000 kilometers—it’s hassle-free and safer. Just make sure to choose the correct filter model for your car to avoid mistakes.
