BMW X3's cabin air filter is located under the grille cover beneath the wipers. Below are the steps for removing the BMW X3 cabin air filter: 1. Open the engine hood, then release the clip at the bottom left corner. 2. Disconnect the wiring harness, paying special attention to remove both the clip and harness together - never pull out just the wiring harness alone. 3. Gently lift the clip upwards, then raise the entire plastic cover to remove the grille cover. 4. Hold the four clips to remove both the filter and plastic housing together, then take out the second-layer filter.
The cabin air filter for the BMW X3 is typically located behind the glove compartment on the passenger side. First, open the glove box - you'll find small clips or buttons on both sides. Gently press them to remove the trim panel, then you'll see the filter housing cover. Unscrew it to access and replace the old filter. Pay attention to align the arrow direction with the fan to ensure proper airflow and filtration efficiency (installing it backward reduces performance). I usually DIY this: a new filter costs around tens of RMB, and all you need is a small screwdriver. Wear gloves to avoid dust - the whole process takes about five minutes. After replacement, the air becomes noticeably fresher, especially in summer when using AC without that musty odor. Check it every six months or 10,000 km - don't neglect this, as prolonged delays can damage the expensive AC system. DIY saves money and builds good maintenance habits.
I think the cabin air filter of the BMW X3 is located on the inner side of the glove compartment on the passenger side. It's not difficult to find - just open the glove box and reach inside, there might be a trim panel to remove before seeing the filter housing. Why change it frequently? It filters dust and pollen, blocks odors and bacteria, keeping the cabin air clean for comfortable breathing, especially important for children or allergy sufferers - safety first. I replace mine every season, the filters are cheap and convenient to buy online. DIY is easy: pull out the old one and insert the new one, just be careful not to install it backwards. After replacement, the AC airflow will become more even. Don't wait until it smells bad - proactive maintenance means peace of mind and better health.
