When the most important particles are passing by this pathway, the bundles of fibers behave like a kitchen area sieve which physically blocks the particles from passing by way of. Nevertheless, when smaller sized particles pass With all the air, as being the air twists and turns, the lesser particles can't sustain Together with the movement in the air and thus they collide Along with the fibers. The smallest particles have little inertia and they always move across the air molecules like they are bombarded by these molecules (Brownian movement).
