FFP1

Respirators may only be used in working environments where no toxic or fibrogenic aerosols or dusts are present. The 4-fold occupational exposure limit (OEL) of FFP1 respirators must not be exceeded. With a separation efficiency of 78%, no more than 25% of the particles may pass through the mask in an FFP1 respirator (total leakage). FFP1 masks are mainly used in the construction industry or in the food industry.

FFP2

FFP2 respirators should be used in work environments where substances hazardous to health and mutagenic substances are present in the air breathed. FFP2 respirators have a separation efficiency of 92%. The occupational exposure limit (OEL) may be 10 times higher than the industry standard. FFP2 protective masks protect against less toxic dusts, mists and smoke.

FFP3

Respirators are suitable for toxic, carcinogenic and radioactive particles. With a separation efficiency of 98%, the mask retains at least 98% of the particles when properly fitted. FFP3 masks are used in laboratories when handling viruses and bacteria or also in wood processing.
