What are dust particles? Everyone should know
Dust particles, also known as particulate matter (PM), are minuscule fragments suspended in the air, invisible to the naked eye but omnipresent in our environment.These particles, ranging in size from a few to tens of micrometres, are about 1/25th the width of a human hair, highlighting their tiny scale.
Dust | Description, Components, & Facts | Britannica
Particle size. Dust particles range in size from 1 to 400 micrometers (μm; 1 μm = 0.001 mm [about 0.00004 inch]). Particles larger than about 100 μm (0.1 mm [0.004 inch]), which is about the width of a human hair, are visible to the unaided eye. Human lungs are capable of filtering out particles as small as 1 μm.
