The National Air Filtration Association (NAFA) defines HEPA filters as being a filter using a minimal efficiency of ninety nine.ninety seven% on 0.3 micrometer particles. HEPA filter’s paper media is made up of micro-glass fibers, artificial fibers, or expanded film like polytetrafluoroethylene (PTFE) that happen to be pleated forwards and backwards like an accordion to form a good and compact filter factor with a sizable area location. This tight pleating is required as the paper incorporates a high resistance to airflow and the media velocity will likely be inside the choice of six fpm (.03 m/s). HEPA filters perform by forcing air from the media’s fine mesh or “net” that traps risky particles such as pm2.
Every single pollutant leads to its very own CADR ranking, which is why you are going to see that air purifiers can have numerous CADR ratings.
