Most of the time, these filters are composed of tangled bundles of fine fibers. These fibers produce a slim convoluted pathway by which air passes. When the largest particles are passing via this pathway, the bundles of fibers behave just like a kitchen sieve which physically blocks the particles from passing as a result of. Nevertheless, when scaled-down particles pass with the air, as being the air twists and turns, the smaller particles simply cannot sustain Together with the motion of your air and therefore they collide with the fibers.
