Ffp2 Nr En 149:2001 + A1:2009 Ce 2841

Filtering Facepiece (abbreviated FFP), where the number at the end denotes the amount of protection, Respirators that adhere to EN149:2001 specifications are made to guard against solids, water-based aerosols, and oil-based aerosols. The three protection levels described in EN149:2001 are FFP1, FFP2, and FFP3, and filtering facepieces are categorized based on filter effectiveness. This study demonstrates that after being sterilized once and twice using a rapid hydrogen peroxide process, FFP2 face masks kept their shape and could hold onto particles in a "quick" test. In times of shortage, FFP2 masks can be sanitized twice and used three times.
