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.

FFP2 and P2 respirators are not NIOSH-approved, so they cannot satisfy OSHA-required workplace use in the US. This guide covers the legal rule, the ended COVID exception, the FFP2-to-N95 and FFP3-to-P100 translation table, voluntary-use cases, the reverse question abroad, and a spec-conversion worked example.
