A one-to-one classification of disposable face masks to a cleanroom class according to ISO 14644-1 is not possible. Recommendations can only be made based on cleanroom specific requirements, e.g. "abrasion resistance" or "particle emission" and, to some extent, „filtration efficiency“. In the VDI guideline 2083 Part 9.2 chapter 6 the user can find additional information.
