When the biggest particles are passing by means of this pathway, the bundles of fibers behave just like a kitchen sieve which physically blocks the particles from passing through. Nonetheless, when smaller sized particles move With all the air, as the air twists and turns, the more compact particles are not able to keep up with the movement on the air and so they collide with the fibers. The smallest particles have little or no inertia and they generally transfer round the air molecules like These are bombarded by these molecules (Brownian movement).
