Particle Size - uwec.edu

Particle Size Sizes. The size of particulates is generally described by the "aerodynamic" diameter of the particles. Common size designations are PM 10 = particles that are 10 micrometers (um) and smaller, PM 4 = particles 4 um and smaller (these are often referred to as "respirable"), and PM 2.5 = particles 2.5 um and smaller (these are often called "fines").
