Air filters help keep your car running smoothly. But how, exactly? This guide to your car’s cabin air filters and engine air filters will help you better understand them — and know when it’s time to change them.
When air enters your car’s cabin, it must pass through your cabin air filter. This car component helps prevent pollution from the road from getting into your lungs while you’re driving.
Similar to the cabin air filter, the engine air filter cleans the air that passes through it. This happens so that your engine remains clean, though, instead of your car’s cabin.
