       There are many nose bridge wires on the market, some are cheaper and some are more expensive. So is there any difference between them. If yes, what is the difference?


       There are roughly two ways to distinguish the quality of the aluminum nose bridge wire in the N95 mask: material, viscosity


       Judging from the surface of the aluminum nose bridge wire of the N95 mask, it is generally smooth and without burrs, and it is not obvious whether it is good or bad. Distinguish from the material, some manufacturers use A1100 as the raw material. This price is relatively cheap, and the bendability is worse. This test can be used to distinguish.

       It can also be seen from the glue of the aluminum nose wire that the glue of some aluminum nose wires is not evenly covered, and the workmanship is not good, especially at the edges of both ends. There are also stickiness. There are many types of hot melt adhesives. Different models have different prices and different stickiness. It is also important to understand what type of hot melt adhesive is used and how sticky is it? How durable is time?
