Common Assortment Efficiency Curve with Filter Assortment Mechanisms HEPA filters are made up of a mat of randomly organized fibers.[sixteen] The fibers are usually composed of polypropylene or fiberglass with diameters among 0.five and a pair of.0 micrometers. Most of the time, these filters are made up of tangled bundles of great fibers. These fibers produce a slender convoluted pathway by which air passes. When the largest particles are passing via this pathway, the bundles of fibers behave similar to a kitchen sieve which bodily blocks the particles from passing by means of.
