The protection must bear the «CE» logo and refer to the EN standard. Respiratory protection can be provided in the form of a half-mask or a full mask. In the case of a half-mask, safety glasses must also be worn to prevent splashing of the eyes. Half masks are designed to protect the respiratory tract against harmful gases and particles. Combined filters protect against particles, gases and vapours. They consist of two superimposed filters: a particle filter (P) and an anti-gas filter (A).
