When the most important particles are passing by means of this pathway, the bundles of fibers behave like a kitchen sieve which bodily blocks the particles from passing via.

The smallest particles have hardly any inertia they usually often shift within the air molecules like They may be bombarded by these molecules (Brownian motion).
