Your cabin air filter filters the air that you breathe in. The air that flows through your vents has to go through the cabin air filter first. This filter catches dust, dirt, debris, smoke, allergens, and mold spores. Over time your cabin air filter will become dirty. When it becomes dirty it restricts the air flow from your heater and air conditioner. It can also accumulate moisture. When it starts to do this those mold spores can grow and so will mildew. This will cause an unpleasant odor that will make your vehicle smell badly. This can be harmful to you and your family. Your cabin air filter should be changed every year. If you have pets, or live in an area with a lot of wildfire smoke and dust then it should be changed more frequently.
