Vintage Collection Efficiency Curve with Filter Assortment Mechanisms HEPA filters are made up of a mat of randomly arranged fibers.[16] The fibers are usually made up of polypropylene or fiberglass with diameters amongst 0.5 and a couple of.0 micrometers. Usually, these filters are composed of tangled bundles of high-quality fibers. These fibers make a slender convoluted pathway by which air passes. When the largest particles are passing by way of this pathway, the bundles of fibers behave similar to a kitchen area sieve which bodily blocks the particles from passing through. However, when scaled-down particles pass Along with the air, as being the air twists and turns, the smaller sized particles can not keep up With all the motion of the air and so they collide with the fibers. The smallest particles have hardly any inertia plus they normally shift throughout the air molecules like They are really bombarded by these molecules (Brownian movement).
