The reasons for the strong odor in the car cabin during winter may include the following:
Long term use and accumulation of air conditioning pipes and filter elements: During the use of automotive air conditioners, the filter element will adsorb dust and odors in the air. If not cleaned and replaced for a long time, it will produce odors. At the same time, dirt and bacteria inside the air conditioning ducts can also produce odors.
Anti slip materials for seats and carpets: Anti slip materials for car seats and carpets can absorb dust and odors during use, and if not cleaned and maintained regularly, they can produce odors.
Smoking in the car: If someone smokes in the car, tobacco smoke will spread and adhere to various parts of the car, resulting in a strange smell.
Lack of air circulation: In winter, due to the large temperature difference between the inside and outside of the car, the windows often close, resulting in a lack of air circulation inside the car and the generation of odors.
To address these issues, the following measures can be taken:
Regular cleaning and replacement of air conditioning filter elements: Regular cleaning and replacement of air conditioning filter elements can avoid the occurrence of odors.
Regular cleaning of seats and carpets: Regular cleaning of seats and carpets can remove dust and odors.
Not smoking in the car: Not smoking in the car can avoid the generation of tobacco smoke.
Regular window opening and ventilation: Regular window opening and ventilation can ensure air circulation in the car and avoid the occurrence of odors.
