The FFP3 mask is Europe's highest disposable respirator class: at least 99% filtration with tight leakage limits under EN 149. This guide covers FFP2 vs FFP3 selection, the UK's APF 20, silica and hardwood-dust uses, valve and NR/R/D markings, US N99/P100 equivalents, and a four-step check for spotting counterfeits.

Face fit testing is the UK's proof that tight-fitting RPE actually seals. This guide covers INDG479's seven-exercise protocol, qualitative vs quantitative methods, Fit2Fit accreditation, the UK's 4/10/20/40 protection-factor ladder, CE vs UKCA status after Brexit, and a worked example fit-testing a site crew with a qualitative kit.

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.
