When the largest particles are passing by means of this pathway, the bundles of fibers behave just like a kitchen area sieve which physically blocks the particles from passing by way of. Having said that, when smaller particles move with the air, given that the air twists and turns, the smaller sized particles can't keep up Together with the motion in the air and thus they collide With all the fibers. The smallest particles have very little inertia and so they generally transfer throughout the air molecules like They're bombarded by these molecules (Brownian movement).
