Vintage Collection Efficiency Curve with Filter Assortment Mechanisms HEPA filters are made up of a mat of randomly organized fibers.[sixteen] The fibers are generally made up of polypropylene or fiberglass with diameters concerning 0.5 and 2.0 micrometers. More often than not, these filters are composed of tangled bundles of high-quality fibers. These fibers develop a slender convoluted pathway through which air passes. When the most important particles are passing through this pathway, the bundles of fibers behave similar to a kitchen sieve which physically blocks the particles from passing by means of. Having said that, when smaller sized particles move With all the air, because the air twists and turns, the scaled-down particles cannot keep up With all the movement in the air and thus they collide While using the fibers. The smallest particles have little inertia and so they constantly move round the air molecules like They're bombarded by these molecules (Brownian motion).

The Countrywide Air Filtration Association (NAFA) defines HEPA filters to be a filter getting a minimum efficiency of 99.ninety seven% on 0.3 micrometer particles. HEPA filter’s paper media is made up of micro-glass fibers, artificial fibers, or expanded movie like polytetrafluoroethylene (PTFE) which have been pleated backwards and forwards like an accordion to form a good and compact filter component with a significant area spot. This limited pleating is needed since the paper contains a high resistance to airflow as well as media velocity is often in the variety of six fpm (.03 m/s). HEPA filters operate by forcing air with the media’s high-quality mesh or “Web” that traps hazardous particles such as pm2.
