When the largest particles are passing via this pathway, the bundles of fibers behave similar to a kitchen area sieve which bodily blocks the particles from passing by way of. However, when smaller sized particles pass with the air, given that the air twists and turns, the lesser particles are not able to sustain Together with the motion from the air and thus they collide Along with the fibers. The smallest particles have little inertia and they constantly transfer within the air molecules like They're bombarded by these molecules (Brownian motion).
