HEPA vs. HE[edit]

@John P. Sadowski (NIOSH): so PAPRs may use High-Efficiency filters that filter particulates but are not High-Efficiency Air filters, or alternately HEPA filters that are not HE filters, if I read Powered air-purifying respirator#Filters correctly? Or are P100 filters HEPA filters[1]? HLHJ (talk) 03:43, 19 August 2020 (UTC)[reply]

HEPA is a certification for air filters in general, not respirators, and it has different standards that are governed by different organizations. The NIOSH standard is probably called HE instead of HEPA to avoid confusion. What it's called is based on whether it's been tested and certified by a certain organization to a certain standard, rather than whether it meets the definition. John P.
