They are mostly loose or unpacked products.

Secondly, look at the appearance and craftsmanship

The sealing rubber ring is soft, elastic, and of uniform thickness; Fake products have rough outer shells, mottled paint surfaces, obvious welding gaps, stiff rubber rings, uneven thickness, and are prone to aging and cracking.

Thirdly, check the internal filter element
The genuine filter element has uniform and neat folds, fine and thick filter material, and no impurities or debris. The central support tube is sturdy and thick; Fake products have messy and sparse folds, thin and transparent filter materials, and a slender central tube that is prone to collapse.

Fourth, check anti-counterfeiting traceability
Authentic products can be scanned and queried on the official website and official account, and the traceability information is complete and available; Fake products with no information or displaying false content when scanned.

Fifth, check the weight
