The functions of the cabin air filter: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the vehicle cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture adsorption capabilities. 4. It prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers and safe driving. It provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. It also effectively sterilizes and deodorizes. 5. It maintains clean air in the cabin, preventing bacterial growth and creating a healthy environment. It effectively separates solid impurities such as dust, filter powder, and abrasive particles from the air. It also effectively blocks pollen, ensuring that drivers and passengers do not suffer allergic reactions that could affect driving safety. Replacement time for the cabin air filter: The cabin air filter should generally be replaced every 8,000-10,000 kilometers driven. The replacement interval can also be adjusted based on the external driving environment. If the environment has significant variations in dryness and humidity, is consistently dry, or has high levels of wind and sand, the filter should be replaced earlier.
As a parent who drives daily, I pay special attention to the air quality inside the car, especially its impact on children. The main function of the cabin air filter is to purify the incoming air by removing dust, pollen, bacteria, and odors. During pollen season or in heavily polluted urban areas, poor filtration can easily trigger sneezing or even asthma in children. I remember one time when I delayed replacing the filter, dust and musty smells accumulated inside the car, making everyone uncomfortable with constant coughing during the drive. Now I inspect and replace it every six months—it's a low-cost measure that significantly improves respiratory health. The filter also reduces unpleasant odors, making the AC airflow fresher, which is particularly noticeable during long trips when closed windows maintain smooth air circulation, creating a safer and more pleasant environment for the whole family. I recommend car owners not overlook this small component; regular maintenance is simple yet effectively prevents health risks.
As a commuter who drives in big cities year-round, the air quality inside my car directly affects my mood during the commute. The cabin air filter plays a significant role—it effectively removes external pollutants, exhaust fumes, and odors, keeping the interior clean and comfortable. When stuck in traffic with the AC on, the filter quickly purifies the air, making breathing easier and reducing fatigue. Once, when my filter was clogged, the airflow weakened and emitted a foul smell, leaving me drowsy on the road and affecting my work. After replacing it promptly, the odors noticeably decreased, and the airflow became stronger again. Though small, the filter makes a big difference. It’s easy to maintain, low-cost, yet greatly enhances the overall driving experience. Especially for those frequently driving in congested areas, it’s as crucial as an air purifier, protecting the respiratory system and eliminating extra hassles.
