Usually, these filters are composed of tangled bundles of wonderful fibers. These fibers make a slim convoluted pathway through which air passes. When the biggest particles are passing by this pathway, the bundles of fibers behave like a kitchen area sieve which bodily blocks the particles from passing by means of.

HEPA filter’s paper media is made up of micro-glass fibers, artificial fibers, or expanded film like polytetrafluoroethylene (PTFE) which can be pleated backwards and forwards like an accordion to form a decent and compact filter ingredient with a considerable area location. This tight pleating is required since the paper includes a high resistance to airflow and the media velocity is usually from the selection of 6 fpm (.03 m/s). HEPA filters work by forcing air from the media’s good mesh or “Web” that traps hazardous particles like pm2.
Polices made by EPA, OSHA, CDC and various federal, state and native authorities organizations answerable for human well being and IAQ difficulties specify HEPA filters for asbestos, lead and mildew abatement, TB and SARS isolation rooms and healthcare renovation tasks.
