Again from the perspective of the appearance of the filter:
First, the glue is full?
Second, the end cover is rust?
Third, the filter paper is broken off and damaged?
These are related to the whole filter quality or not?
Our technical department will follow the market sample test, take you into the mysteries of the internal filter!
