Classic Assortment Efficiency Curve with Filter Selection 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 concerning 0.5 and a pair of.0 micrometers. More often than not, these filters are composed of tangled bundles of wonderful fibers. These fibers produce a slim convoluted pathway through which air passes. When the largest particles are passing as a result of this pathway, the bundles of fibers behave just like a kitchen sieve which physically blocks the particles from passing by means of. Nonetheless, when lesser particles move Using the air, as the air twists and turns, the smaller particles cannot sustain While using the motion of your air and thus they collide Along with the fibers. The smallest particles have very little inertia they usually constantly shift within the air molecules like They are really bombarded by these molecules (Brownian motion).

This product does it all, and we discovered ourselves using it each and every day at the time we brought it residence, whether or not it had been to cool matters down or maintain the air refreshing.
