Filtering facepieces after DIN EN 149
The three protection classes as defined by EN 149 distinguish between the quantity of the filtered particles rather than their size.
FFP1 respirators filter out at least 80% of particles, while FFP2 respirators filter out 94% and FFP3 filters 99,95%. The more particles that need to be filtered, the more filter material layers are required. For this reason, masks in the higher protection classes are thicker, which results in higher breathing resistance.
In order to reduce the breathing resistance of FFP2 and FFP3 masks, uvex has developed the unique High Performance masks, which offer lower breathing resistance and ensure improved temperature regulation.
