There are different types of face mask and Coranvirus considerations. There are three main types of Filtering Face Piece (FFP) masks: FFP1, FFP2, and FFP3. These types are mainly used in industries for the protection against airborne particles. There should be CE marked to show that the design has been tested to a recognised standard. They must also be marked with that standard, which for disposable respirators, the standard is EN 149: 2001.
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.
