The Nationwide Air Filtration Association (NAFA) defines HEPA filters as a filter using a minimum amount efficiency of ninety nine.ninety seven% on 0.three micrometer particles. HEPA filter’s paper media is composed of micro-glass fibers, artificial fibers, or expanded film like polytetrafluoroethylene (PTFE) which are pleated forwards and backwards like an accordion to form a good and compact filter element with a big surface region. This tight pleating is necessary as the paper contains a high resistance to airflow and the media velocity is usually within the array of six fpm (.03 click here m/s).

HEPA filter efficiency is outlined at a specific particle size, called one of the most penetrating particle size (MPPS). The MPPS would be the particle size that can most commonly passes with the filter material.
