microns. But w h a t is a 10 micron particle? W ell,
th e e ye of an a v e ra g e s ize sew ing n eed le is
abo ut 7 5 0 m icrons across, and th e dot in the

large con centrations, such as a puff of sm o ke.
Y o u r electronic air c le a n e r can rem ove even

Although particles 1 micron and sm a lle r m ake
