Guide to Dust Mask Ratings
Dust Masks protect workers against airborne particles such as dusts and powders. Different masks provide different levels of protection, so it’s important to find the right level of protection for your workplace. EN 149 designates three dust mask ratings; FFP1, FFP2, and FFP3. You can find out more about these ratings below.
FFP1 Dust Masks
FFP1 Dust Masks protect against low levels of dust, as well as solid and liquid aerosols. It protects against materials in concentrations up to 4x occupational exposure limit (OEL) or 4x assigned protection factor (APF). FFP1 Dust Masks are suitable for hand sanding, drilling, and cutting.
FFP2 Dust Masks
FFP2 Dust Masks protect against moderate levels of dust, as well as solid and liquid aerosols. FFP2 Dust Masks have a higher level of protection than FFP1 – FFP2 masks protect against materials in concentrations up to 12x OEL or 4x APF. FFP2 masks are ideal for plastering and sanding.
FFP3 Dust Masks
FFP3 Dust Masks protect against higher levels of dust. They also protect against solid and liquid aerosols. FFP3 masks protect against materials in concentrations up to 50x OEL or 20x APF. FFP3 masks are suitable for handling hazardous powders, such as those found in the pharmaceutical industry.
