HEPA filter’s paper media is made up of micro-glass fibers, artificial fibers, or expanded movie like polytetrafluoroethylene (PTFE) that happen to be pleated backwards and forwards like an accordion to form a decent and compact filter factor with a considerable floor place. This restricted pleating is required since the paper includes a high resistance to airflow and the media velocity is generally during the variety of six fpm (.03 m/s). HEPA filters get the job done by forcing air with the media’s fine mesh or “Internet” that traps harmful particles for instance pm2.
