Why it matters: The cabin air filter cleans the air coming through your vents — it doesn't affect the engine. A clogged one causes weak airflow, musty smells and tired AC performance.
On most cars it sits behind the glovebox and takes 5–10 minutes to swap with no tools — one of the easiest DIY jobs there is. Filters run $10–25.
