Usually, these filters are made up of tangled bundles of fantastic fibers. These fibers develop a narrow convoluted pathway through which air passes. When the biggest particles are passing by way of this pathway, the bundles of fibers behave like a kitchen area sieve which physically blocks the particles from passing by means of. On the other hand, when more compact particles go Using the air, since the air twists and turns, the smaller sized particles can not keep up While using the motion from the air and therefore they collide Using the fibers. The smallest particles have little inertia and so they often shift throughout the air molecules like they are bombarded by these molecules (Brownian motion).
