FFP1 class medical respirators
FFP1
— the basic protection class for respirators offers around 85% filtration of particles sized 0.3 microns or larger. It is appropriate for scenarios where the maximum permissible concentrations (MPC) of pollutants are exceeded by less than 4 times.These respirators are primarily designed for safeguarding against larger solid particles, such as construction cement, wood and metal shavings, and non-toxic dust. While not specifically rated for continuous exposure to liquid aerosols, FFP1 respirators can offer intermittent protection, for instance, from someone nearby sneezing. Consequently, masks in this class are suitable for household prevention of infections transmitted through droplets, such as COVID-19, flu, or the common cold. However, for protection against airborne diseases like tuberculosis or chickenpox and for use in infectious diseases hospitals, more robust protection is necessary.
Considering the information provided, FFP1 respirators are suitable for medical use primarily in uncomplicated situations with a relatively low but consistent risk of contracting infections transmitted through droplets. For instance, they could be a viable option for sales assistants or other personnel engaging with people in everyday non-medical activities. However, models with a valve are generally unsuitable for such purposes; refer to "Additional — Valve" for more details.
