When the biggest particles are passing by this pathway, the bundles of fibers behave similar to a kitchen sieve which bodily blocks the particles from passing by. On the other hand, when smaller particles move Together with the air, as being the air twists and turns, the scaled-down particles cannot sustain Using the motion on the air and so they collide While using the fibers. The smallest particles have little inertia and they often shift across the air molecules like They can be bombarded by these molecules (Brownian movement).
