Air filter element: 
1. The filter element is the core component of the filter. It is made of special materials and is a vulnerable part that requires special maintenance and maintenance;
2. When the filter has been working for a long time, the filter element in it has intercepted a certain amount of impurities, which will cause an increase in pressure and a decrease in flow rate. At this time, it needs to be cleaned in time;
3. When cleaning, be careful not to deform or damage the filter element;
4. Generally, the service life of the filter element is different according to the different raw materials used, but as the use time is extended, the impurities in the water will block the filter element, so generally the PP filter element needs to be replaced in three months; the activated carbon filter element needs to be replaced in six months ; As the fiber filter element cannot be cleaned, it is generally placed in the back end of PP cotton and activated carbon, which is not easy to cause clogging; the ceramic filter element can usually be used for 9-12 months；
5. The filter paper in the equipment is also one of the key points. The filter paper in high-quality filter equipment usually uses superfine fiber paper filled with synthetic resin, which can effectively filter impurities and has a strong dirt storage capacity. According to relevant statistics, when a passenger car with an output power of 180 kilowatts travels 30,000 kilometers, the impurities filtered out by the filtering equipment are about 1.5 kg. In addition, the equipment also has great requirements for the strength of the filter paper. Due to the large air flow, the strength of the filter paper can resist strong airflow, ensuring the efficiency of filtration and prolonging the service life of the equipment.
