Home / News / In addition to filtering particles in the air, do cabin filters have other functions, such as regulating the humidity in the car?
Cabin filters, also known as in-car air filters or air conditioning filters, are an important part of the air purification inside the car. In addition to the basic function of filtering particles in the air, Cabin filters also play more roles in modern cars. Although the function of directly regulating the humidity in the car is not traditionally included in its scope, it plays a vital role in improving the air quality in the car, protecting the health of passengers and improving driving comfort.
The primary function of Cabin filters is to filter particles from the air entering the car, including dust, pollen, smoke, etc. These particles not only affect the air quality in the car, but may also cause allergic reactions or respiratory problems. High-quality Cabin filters use a multi-layer filtering structure, such as a non-woven fabric layer and an activated carbon layer, which can effectively filter out particles in the air and provide passengers with a fresher air environment.
In addition to filtering particles, Cabin filters often contain activated carbon or other adsorbent materials to absorb harmful gases in the air, such as formaldehyde, benzene, TVOCs (total volatile organic compounds), etc. These harmful gases often come from car interior materials, external environmental pollution, etc., and pose a potential threat to the health of passengers. By absorbing these harmful gases, Cabin filters can further purify the air in the car and improve the health of the passengers.

Hyundai Cabin filters are also designed with bacteria, viruses and other microorganisms in mind. Some high-end models or professional filter brands use materials or coatings with antibacterial and antiviral functions to effectively prevent these microorganisms from growing and spreading on the filter. This helps reduce the number of microorganisms in the air in the car and reduces the risk of occupants contracting diseases.
Although Cabin filters do not directly adjust the humidity in the car, they can significantly improve driving comfort by purifying the air, removing odors and harmful gases. Fresh air and a comfortable environment can help reduce driver fatigue and improve driving concentration and safety.
Although Cabin filters themselves do not have the function of directly adjusting the humidity in the car, they can indirectly affect the humidity in the car to a certain extent. For example, in a humid environment, Cabin filters can filter out moisture and humidity in the air and reduce the feeling of humidity in the car. At the same time, by keeping the air in the car circulated and purified, Cabin filters help prevent mold and bacteria from growing in the car, thereby indirectly maintaining the dryness and cleanliness of the car environment.
In addition to filtering particles in the air, Cabin filters also have multiple functions such as absorbing harmful gases, preventing the spread of bacteria and viruses, and improving driving comfort. Although it does not have the function of directly regulating the humidity in the car, it can indirectly affect the humidity in the car to a certain extent by purifying the air and keeping the car environment clean and dry, providing passengers with a healthier and more comfortable driving environment. Therefore, regular replacement and maintenance of Cabin filters is of great significance to maintaining the air quality in the car and protecting the health of passengers.
