History of HEPA Filters High Efficiency Particulate Air filter Copyright National Air Filtration Association 2006 Rev. 2

To Be A HEPA Filter “Throwaway extended-medium dry-type filter in rigid frame having minimum particle-collection efficiency of 99. 97% (that is a maximum particle penetration of of 0. 03%) for 0. 3 µm particles of thermally-generated DOP particles or specified alternative aerosol. ” --IEST Copyright National Air Filtration Association 2006 Rev. 2

Background on HEPA Filters Copyright National Air Filtration Association 2006 Rev. 2

HEPA Filter Testing • HEPA filters should be factory tested to assure the minimum efficiency 99. 97% on 0. 3 micrometer particles • Personnel installing/replacing should be trained in proper installation – proper personal protection • In-place challenging for integrity is highly recommended Copyright National Air Filtration Association 2006 Rev. 2
