1. Close the windows: Harmful particles in the air can easily follow the flying dust and enter the interior space through the windows. Closing the windows and sunroof effectively blocks pollutants from the outside of the car, but it does not mean complete isolation.
1. Close the windows: Harmful particles in the air can easily follow the flying dust and enter the interior space through the windows. Closing the windows and sunroof effectively blocks pollutants from the outside of the car, but it does not mean complete isolation. Therefore, the air quality inside is not particularly bad, so don't open any windows on hazy days. If you feel that the air in the car is cloudy or in good weather, remember to open the windows for a short time to let the air in the car circulate.
2. Open the internal circulation: After closing the window, the internal circulation of the car air conditioner can be opened to form a closed circulation airflow in the cabin. Internal circulation can effectively bring external dust and harmful gases into the car. At the same time, the car air conditioner has the function of air filtration, which can further reduce the concentration of suspended particles in the car, but the air filter element can only achieve a rough filtering effect. However, it is recommended that if you run at high speed or stay in the car for too long, briefly turn on the external circulation to update the air in the car.
3. Regularly clean and replace the air conditioner filter element: the engine air intake filter element and the air conditioner filter element are equivalent to the masks of the car, absorbing a large amount of dust, particles and pollutants in the air. However, after accumulating too much pollutants, the air intake efficiency will be reduced, resulting in a decrease in engine power and insufficient air volume of the air conditioner. More importantly, the pollutants on the air-conditioning filter element will breed bacteria or mildew, causing the air-conditioning odor, which not only affects the ride comfort, but also poses a threat to health. The influence of the air conditioner filter element on the air quality in the car is actually very important. The domestic brother recommends cleaning the air conditioner filter element with a high-pressure air gun at least once every six months, and replaces it every two years.
