EN 149 grades European disposable respirators FFP1, FFP2, and FFP3; EN 143 grades P1-P3 filters. This guide decodes the classes, the CE marking string, NR/R/D suffixes, gas-filter types, and Regulation (EU) 2016/425 — plus how the European system maps to NIOSH N95 and P100, with a dual-certified GVS Elipse worked example.

CBRN stands for chemical, biological, radiological, and nuclear — but a “CBRN-rated” filter can mean very different things depending on who certified it. This reference decodes NIOSH CBRN approvals and European ABEK ratings, explains expiry and storage rules, and covers the hazards no filter can stop.
