Respiratory protection in the form of disposable dust masks come in three respirator ratings:
FFP1, FFP2, and FFP3 - FFP stands for "Filtering Face Piece" and the number denotes the level of protection.
Many people shorten these acronyms even more as P1, P2 & P3 - but the meaning and level of respiratory protection is the same.
