The additional markings, such as FFP1, FFP2, and FFP3 indicate the protection level available if you use it correctly. In response to Coronavirus COVID-19, the FFP3 mask will provide the best level of protection, though there are no guarantees that they will protect you.
Always carry out a pre-use check before you put on a mask, check that it fits according to manufacturer’s instructions, and test it for effectiveness with a simple breath test. Readjust the respirator if you detect any leakage around your face.
