I. Introduction
When the car is driving, it is necessary to inhale the outside air into the compartment, but the air contains many different particles, such as dust, pollen, soot, abrasive particles, ozone, odor, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene and so on.
If there is no filter to filter, once these particles enter the compartment, not only will the car be polluted and the performance of the cooling system be reduced, but also people will have allergic reactions after inhaling dust and harmful gases, and their lungs will be damaged, and they will be agitated by ozone stimulation and have the influence of odor, which will affect driving safety. The high-quality air filter can absorb powder particles, relieve respiratory pain, reduce the stimulation to allergic people, make driving more comfortable and protect the cooling system.
Please note that there are two kinds of filter elements, one is without activated carbon, and the other is with activated carbon. The filter element with activated carbon not only has the above functions, but also has the effect of absorbing a lot of odor. The general replacement cycle of filter element is 8000 ~ 00 km.
Second, the main role
1. Ensure that unfiltered air will not enter the carriage;
2. Separate solid impurities such as dust, pollen and abrasive particles from the air;
3. Absorb moisture, soot, ozone, odor, carbon oxides, SO2, CO2, etc. in the air;
4. The automobile glass will not be covered with steam, so that drivers and passengers can see clearly and drive safely;
5. Provide fresh air to the driver’s room and effectively intercept pollen to prevent drivers and passengers from inhaling harmful gases;
6, strong sterilization and deodorization, to ensure that the air in the driving room is clean and does not breed bacteria, creating a healthy environment.
Third, the replacement tips
1. If the air flow blown out is significantly reduced, the filter element may be blocked. Clean the filter element first, or replace it if necessary;
2. The cleaning frequency depends on the road conditions (dusty roads, etc.);
3. The filter element should be correctly installed in its position. When the filter element is removed, it may cause dust-proof performance degradation and affect performance;
4. The general replacement cycle of filter element is once every 00 kilometers. If it is a city with poor air quality, it is suggested that the owner replace the filter twice a year to ensure health.

5. How to advise the owner to replace the air filter?
1. Before service, seasonal reminder:It is more common that SA can remind car owners to do routine maintenance with the change of seasons, car habits and environment. For example, the four-season insurance project launched by some enterprises is worth learning. On the one hand, it reflects the care for the owner, on the other hand, the owner will get used to such routine maintenance.
2. In service, service combined with sales:When the technician makes a routine inspection of the vehicle system, SA needs to make a detailed record of the use of the air filter, which can be actually displayed for the customer at this time. The advantage of the physical display is that it can make the owner have a visual impact. At the same time, explain the common sense of filters to customers, and focus on the health of car owners rather than product knowledge.
You can talk with the car owner about topics such as P.5, exhaust gas, bacteria and second-hand smoke in the car.
3. After the service, pay a return visit:Ask the owner about the experience of using the product after replacement, and encourage the owner to evaluate the product and service. The evaluation can be fed back to other departments of the company in time.
