Typical Selection Efficiency Curve with Filter Assortment Mechanisms HEPA filters are made up of a mat of randomly arranged fibers.[sixteen] The fibers are typically composed of polypropylene or fiberglass with diameters among 0.five and a couple of.0 micrometers. Most of the time, these filters are made up of tangled bundles of great fibers. These fibers develop a slim convoluted pathway through which air passes. When the most important particles are passing by way of this pathway, the bundles of fibers behave similar to a kitchen sieve which bodily blocks the particles from passing by. Even so, when more compact particles go Using the air, given that the air twists and turns, the lesser particles are not able to keep up Using the movement on the air and thus they collide with the fibers. The smallest particles have little inertia they usually often go round the air molecules like They can be bombarded by these molecules (Brownian motion).

This slows down the particle’s path and increases the likelihood of the particle currently being captured via the media and website become trapped. Diffusion is most effective with great fibers and intensely lower air velocities.
These recommendations were being The idea of our assortment course of action and include the subsequent issues.
