Measuring A Strainer Screen: Microns vs. Mesh
Mesh. Mesh is a bit more straightforward compared to microns. Take one square inch of filtering material (screen) and count the holes in it. If you have 80 openings in that area, then you have an 80mesh screen. If you have 200, then it is 200mesh and so forth. Therefore, the higher the mesh number, the smaller the particles that are filtered.
