Identify true and false filter elements

Identify true and false filter elements Look at the filter material. The main filter material of the air filter is filter paper. At present, the filter filter paper mainly uses domestic paper and imported paper. Both domestic and imported paper have good filtering performance, and the inferior filter paper used by the fake filter element cannot prevent dust from entering the engine. This will affect the normal operation of the engine. The color of the filter paper of the general genuine filter element is uniform, and the paper surface is relatively flat; while the color of the filter paper of the poor quality filter element is not uniform, the paper surface is fluffy, and the texture is very poor. Look at the gel quality of the filter element; at present, the structure of the filter element is generally composed of filter paper and rubber adhesion, and the gel quality of the true and false filter elements is also different. The rubber of the genuine filter element has a good texture and is flexible, while the rubber of the fake filter element is soft and has a poor texture. The easier way to distinguish is to fold the air filter in half. After loosening, the genuine filter will quickly return to its original state, and the fake filter will not adhere well to the filter paper due to the rubber texture problem, and the middle part of the fold is obvious.
