Tight-fitting FFP masks reliably protect the wearer from viruses. These respirators filter even the smallest particles and aerosols from the air. Respirators without an exhalation valve prevent the mask wearer from contaminating his environment with exhaled droplets.

How long can I wear the masks at a stretch?
The BGW’s recommendation on the maximum wearing times, the recovery period and the necessary breaks when using FFP2/FFP3 masks is based on DGUV regulation 112-190 “Use of respiratory protective devices”. According to this regulation, the maximum wearing time is two hours with a subsequent minimum recovery time of 30 minutes. In the case of an FFP mask without an exhalation valve, the maximum wearing time is 75 minutes with a subsequent minimum recovery period of 30 minutes.
