1. Look at the thickness of the inner  skeleton of  vacuum pump exhaust  filter element.

Generally, quality filter element inner framework is between 0.8mm-1.5mm, but some filter factory  reduce the skeleton to 0.3mm-0.5mm in order to reduce raw material cost, there is no difference in appearance, but it seriously affects the pressure resistance of vacuum pump  filter element. .

3. Look at the glue of  vacuum pump filter element

At present, the structure of the filter element is generally composed of filter material,inner framework,  rubber etc. Of course,the glue of  genuine and fake  vacuum pump filter element is also different. The rubber of the genuine filter element has better texture and elasticity, while the rubber of the counterfeit filter element is soft and the texture is poor. The easier way to identify is to fold the air filter element . After loosening, the high-quality filter element quickly returns to its original state, while the fake  vacuum pump air filter element does not adhere well to the filter paper due to the rubber texture problem, and the middle mark of the fold is obvious.
