For example a 100 mesh sieve, said every inch has 100 mesh sieve. The larger the mesh number, the finer the particle size is described; the smaller the mesh, indicating the greater material size. Sieve particles that can pass through the screen mesh size. Filter cartridges, filter whole Xin (certified), filter by Anping Xin filter plant to provide.
