How to distinguish the quality of automobile air filter? These three points are enough.

Xiaobai's car went into the factory for overhaul because of engine jitter. The result of the inspection is that the engine throttle is dirty. Maintenance personnel said that in addition to deep cleaning, it is also recommended to check and replace the engine air filter. Faced with this situation, Xiao Bai is very confused, because the air filter was just replaced by him not long ago. Maintenance personnel removed the air filter for inspection and found that the air filter was inferior. It is understandable that car owners buy and replace vehicle consumables to save maintenance costs, but not everyone can accurately judge the quality of products, which also provides an opportunity for counterfeit and shoddy products. Today, I would like to introduce three key points to identify inferior air filters. Identification point 1: filter material status In order to ensure the filtering effect, the filter materials of genuine air filtration are closely arranged, and the parts in the sealing strip are all effective filtering areas. Inferior air filter products will reduce the amount of filter materials in order to save costs. The filtration area of inferior air filtration is thin, the number of filter materials is obviously small, and the structure is loose. It is difficult for this kind of filter material to provide good filtering effect continuously, which leads to impurities entering the engine. Another way to save the cost of inferior air filtration is to thicken the sealing strip, thus reducing the consumption of filter materials and simplifying the arrangement process of filter materials. The increase of sealing area will reduce the air circulation area, and the engine may lose power because it cannot get enough intake air. The reduction of filter material area will also speed up the complete blockage of air filter due to impurity accumulation. Discriminating point 2: Sealing strip status The sealing strip of paper air filter is usually made of rubber, which is used to eliminate the gap between the filter element and the air filter housing and prevent air from entering the engine without filtering. The sealing strip around the air filter should have good plasticity and flexibility. If you find that the newly bought air filter sealing strip is uneven or easily damaged by external forces, it means that you are likely to encounter inferior or counterfeit products. If it is found that the boundary between air filter sealing strip and filter material is very irregular, it usually means that air filter manufacturers are backward in production technology and ignore quality supervision, so it is difficult to guarantee product quality. In addition, the sealing strip of the air filter is close to the nose. If you can smell the pungent rubber smell, it means that the sealing strip is made of poor material, which is very common in inferior air filtration. Discrimination point 3: The packaging standard is a regular brand air filter product, and the product number, applicable model, inspection certificate and other information will be printed on the outer packaging. The main body of the product is usually wrapped in inner packaging to avoid damaging the product during transportation. Well-known suppliers will also print trademark, product number, production date and other information on the side of air filter products. If the information is not printed, it is inferior or forged. Summary When purchasing air filters, please try to choose products of well-known brands and buy them from their authorized dealers or authorized network channels. When buying automobile consumables, it is very likely to buy inferior products, which will bring many adverse effects to vehicles. Mahler brand engine air filter products cover a wide range of models and original quality. It is recommended to replace the engine air filter every 15000 km. In areas with more sandstorms and serious air pollution, the interval between replacing air filters should be shortened appropriately.
