How to Use the PM2.5 Filter in Cars?
2 Answers
PM2.5 filters in cars are generally divided into two types: built-in and external. 1. The built-in type is integrated into the vehicle's air conditioning system. Some models with automatic air conditioning do not require manual operation of the PM2.5 filter, as the system controls it automatically. 2. The external PM2.5 filter is usually integrated into the front center armrest, with an on/off button on the armrest that can be pressed to activate it. Below is a related introduction to the PM2.5 filter in cars: 1. PM2.5, also known as fine particulate matter, can remain suspended in the air for a long time. The higher the PM2.5 content in the air, the more severe the air pollution. 2. The PM2.5 filter in cars is designed to filter out PM2.5 particles from the air. PM2.5 particles can be inhaled into the lungs, posing significant health risks, especially to sensitive individuals. The PM2.5 filter functions to filter these harmful particles from the air.
If you're driving a car equipped with PM2.5 filtration, I've found the simplest method is to press the air purification button on the center console immediately after starting the vehicle—usually marked with an air quality icon. Then, select the recirculation mode based on weather conditions to block external pollution, such as switching directly to recirculation during smoggy days. Don't forget to check the air conditioning system settings; many models can automatically adjust airflow by linking with the PM2.5 sensor—I do this frequently, especially during city traffic jams, as it helps reduce particulate concentration inside the cabin. Regular filter replacement is also crucial; I recommend checking it every six months or 10,000 kilometers to avoid clogging and maintain filtration efficiency. Overall, daily use is about forming habits—activate the filtration system as soon as you get in the car to protect respiratory health.
