The 5-Second Trick For hepa filters

Basic Collection Efficiency Curve with Filter Selection Mechanisms HEPA filters are composed of a mat of randomly organized fibers.[sixteen] The fibers are typically composed of polypropylene or fiberglass with diameters among 0.five and 2.0 micrometers. Most of the time, these filters are composed of tangled bundles of fine fibers. These fibers create a slim convoluted pathway by which air passes. When the biggest particles are passing by means of this pathway, the bundles of fibers behave just like a kitchen sieve which bodily blocks the particles from passing through. However, when scaled-down particles pass with the air, as being the air twists and turns, the smaller particles can not sustain Together with the movement with the air and therefore they collide Along with the fibers. The smallest particles have little or no inertia they usually generally go throughout the air molecules like they are bombarded by these molecules (Brownian motion).
