Product recommendation based on cleanroom classes
Air cleanliness class EN ISO 14644-1
particulate monitored areas
Hygiene zones according to GMP
microbiological monitored areas
A one-to-one classification of 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". In the VDI guideline 2083 Part 9.2 the user can find additional information.
