Where is the cabin air filter located in a Volvo V40?

Volvo V40's cabin air filter is located on the passenger side, beneath the glove compartment towards the left position. The cabin air filter requires regular replacement. Failure to replace it periodically may lead to the following issues: 1. Severely clogged filters will increase intake resistance and reduce engine power. 2. Increased fuel intake may cause an overly rich air-fuel mixture, resulting in poor engine performance, higher fuel consumption, and increased carbon deposits. 3. In humid environments, the cabin air filter is prone to mold and bacterial growth, leading to musty or foul odors when using the air conditioning. 4. The activated carbon in the cabin air filter loses its adsorption and filtration efficiency over prolonged use.
Last year, I replaced the cabin air filter on my V40 by myself and found it located near the passenger footwell. Specifically, after lifting the floor mat, there's a small panel beneath the glove compartment that can be pried open to reveal the filter housing. The replacement process isn’t difficult—first, use a socket wrench to loosen two screws, then remove the old filter while paying attention to the arrow direction. The new one fits snugly once installed. Regularly changing the filter is crucial—every 6 months—to prevent dust and odors in the car, ensuring fresher air while driving. After trying it, I even noticed improved airflow from the AC. I recommend keeping spare filters at home and doing it yourself to save both time and money on dealership visits.
I've been driving the V40 for several years, and the cabin air filter is located in the footwell on the passenger side. Just lift the floor mat or footwell liner, and you'll see a plastic clip. Pry it open to reveal the filter. Replacing it is quite convenient—all you need is a small screwdriver or you can even do it by hand. Just make sure to align it correctly and avoid installing it backward to prevent airflow issues. If the filter gets dirty and isn't replaced in time, the AC may produce noise or a musty smell, affecting cabin comfort. I usually replace it once between spring and summer, so I don't have to worry about odors when using the heater in winter. Keeping the cabin air clean significantly improves the overall driving experience.
