More often than not, these filters are made up of tangled bundles of great fibers. These fibers develop a slender convoluted pathway by which air passes. When the biggest particles are passing via this pathway, the bundles of fibers behave similar to a kitchen sieve which bodily blocks the particles from passing by.

is the mechanism by which the smallest particles are captured at decrease air velocities. As polluted air passes in the filter media the smallest particles move erratically or an in zig-zag pattern from higher concentrated regions, this is named Brownian Movement.
