EN 143

Respiratory protective devices are a special type of PPE, manufactured to protect workers from inhaling hazardous substances in the air of the workplace. These masks are used as a last resort in the hierarchy of control measures, where an adequate control of exposure is not possible with other means. The filters are one of their components and they are inserted on the face masks and half-face masks to capture solid and/or aeriform contaminants. They are characterised by colours or coloured stripes to protect against different types of contaminants while those protecting against dust are white.
UNI EN 143 dust filters are designed to filter solid particles such as glass wool and dust from demolitions. They are classified P1, P2, P3 according to their filtering capacity.
