Classic Selection Efficiency Curve with Filter Selection Mechanisms HEPA filters are made up of a mat of randomly arranged fibers.[sixteen] The fibers are generally made up of polypropylene or fiberglass with diameters concerning 0.5 and 2.0 micrometers. Most of the time, these filters are made up of tangled bundles of fantastic fibers. These fibers produce a narrow convoluted pathway by which air passes. When the most important particles are passing by way of this pathway, the bundles of fibers behave similar to a kitchen area sieve which physically blocks the particles from passing by way of. Nevertheless, when scaled-down particles go Together with the air, as being the air twists and turns, the more compact particles cannot sustain Together with the motion of your air and therefore they collide Using the fibers.
