Classic Assortment Efficiency Curve with Filter Assortment Mechanisms HEPA filters are composed of a mat of randomly arranged fibers.[16] The fibers are generally composed of polypropylene or fiberglass with diameters among 0.5 and a couple of.0 micrometers. Most of the time, these filters are made up of tangled bundles of fantastic fibers. These fibers create a slender convoluted pathway by which air passes. When the largest particles are passing through this pathway, the bundles of fibers behave like a kitchen sieve which physically blocks the particles from passing by way of. Even so, when scaled-down particles move Together with the air, as the air twists and turns, the smaller particles are not able to sustain Together with the movement on the air and therefore they collide Together with the fibers. The smallest particles have little inertia they usually generally shift round the air molecules like They may be bombarded by these molecules (Brownian movement).
