FFP2 masks are a “Filtering Face Piece” as defined in Europe by the EN 149 standard. These mechanical filters are used in what is technically called “respirators”, and more commonly just known as “FFP masks”. While similar to KN95 or N95 masks, FFP2 masks have distinct features and follow a different regulatory standard.
FFP2 masks are considered Personal Protective Equipment (PPE), as they protect the person wearing them against particulates such as dust droplets, particles, and aerosols.
This mask is normally used in construction, the pharmaceutical industry, the glass industry, foundry or agriculture. It effectively filters out powdered chemicals. It can also protects against respiratory viruses like avian influenza, Covid-19 or SARS.
According to the WHO and several health authorities, FFP2 masks are recommended primarily for health workers that are in regular contact with Covid-19.
FFP masks come in 3 types according to EN 149:2001+A1:2009:
