What Causes the Bad Smell Inside the Car?

[DelWilliam]

Causes of bad smell inside the car: 1. Odors from items in the car: such as smoking, eating, or placing unclean items in the car; 2. New car smell: When the car leaves the factory, the plastic panels or rubber rings inside the car may contain substances like formaldehyde that have not yet dissipated, which can produce a certain odor; 3. Air conditioning odor: If the air conditioning filter is not cleaned for a long time, it can accumulate bacteria and dirt. When air passes through these substances and circulates into the car, it can produce an unpleasant smell. Tips to avoid bad smells: 1. Try not to eat strongly flavored food in the car; 2. Avoid placing fragrances or similar items in the car; 3. When using the air conditioning, try to use the external circulation mode; 4. After purchasing a new car, promptly remove the plastic protective films inside the car.
