The graph below shows different types of
material and the average size of dust particle they create in
microns. It is critical to know the fractional filter efficiency of
the filters when working with dust collection equipment. Different
material has various ranges of particle size and if your dust
vacuum filters are unable to capture that size of dust particle the
health of your employees and others can be put at risk.

The
size of contaminants and particles are usually described in
microns, a metric unit of measure where one micron is
one-millionth of a meter. There are 25,400 microns in
one inch. The eye can see particles around 40 microns.
