The main filter material of the air filter element is filter paper, and now the filter paper of the filter element mainly adopts domestic paper and imported paper.
Both domestic and imported paper have good filtering performance, and the inferior filter paper used in the counterfeit filter element cannot prevent dust from entering the engine, thereby affecting the normal operation of the engine.
Generally, the color of the filter paper of the genuine filter element is uniform, and the paper surface is relatively flat; while the color of the filter paper of the inferior filter element is not uniform, the paper surface is hairy, and the thickness is very poor.
Second look at the colloid of the filter elementNowadays, the structure of the filter element is generally composed of filter paper and rubber, and the gel quality of the real filter element is also different.
The rubber of the genuine filter element has better viscosity and elasticity, while the rubber of the counterfeit filter element is soft and has poor size.
The easier way to distinguish is to fold the air filter element in half. After loosening, the genuine filter element will quickly return to its original shape, while the counterfeit filter element does not adhere well to the filter paper due to the size of the rubber, and the center of the fold is obvious.
