Mesh Size (Mesh) Particle Size Range (millimeters, mm) Common Application Notes
4-8 mesh ~ 4.75 - 2.36 mm Very large particles, used in large industrial equipment, water treatment systems, for handling high-flow, high-turbidity water bodies.
6-12 mesh ~ 3.35 - 1.70 mm Large particles, commonly used in air purification, chemical tower packing, etc.
8-16 mesh ~ 2.36 - 1.18 mm General industrial-grade size, used in water treatment, chemical filtration, etc.
10-20 mesh ~ 2.00 - 0.85 mm
12-30 mesh ~ 1.70 - 0.60 mm Medium particles, widely used, such as in drinking water filtration, gold extraction, etc.
20-40 mesh ~ 0.85 - 0.425 mm One of the most commonly used specifications, very suitable for household water purifiers (such as filter element filling), sugar liquid decolorization, wine processing, etc.
30-60 mesh ~ 0.60 - 0.25 mm Finer particles, used in fine chemicals, gas phase adsorption, small filter elements, etc.
40-80 mesh ~ 0.425 - 0.18 mm Fine grade, commonly used in laboratories, reagent purification, special gas phase adsorption.
80-120 mesh ~ 0.18 - 0.125 mm The starting range of powdered activated carbon, used in liquid phase decolorization, refining, etc.
Above 200 mesh < 0.074 mm Usually classified as powdered activated carbon, mainly used in liquid phase decolorization and wastewater treatment, separated by sedimentation or filtration after stirring and mixing.
