HEPA is really an acronym that means High Efficiency Particulate Air. The Nationwide Air Filtration Association (NAFA) defines HEPA filters as a filter getting a minimal efficiency of 99.97% on 0.3 micrometer particles. HEPA filter’s paper media is made up of micro-glass fibers, synthetic fibers, or expanded movie like polytetrafluoroethylene (PTFE) which have been pleated back and forth like an accordion to form a decent and compact filter component with a significant floor spot. This restricted pleating is necessary as the paper has a high resistance to airflow plus the media velocity is normally in the variety of 6 fpm (.03 m/s). hepa filters for hvac HEPA filters do the job by forcing air through the media’s great mesh or “net” that traps hazardous particles for instance pm2.
To illustrate this, look at that a person micron is one particular-millionth of a meter, which could be about one hundred th the width of the human hair (according to the human being, needless to say).
