How can a portable HEPA filter unit help control TB?
Portable HEPA filtration units recirculate room air, and the HEPA filters effectively remove all particles from the air in the size range of droplet nuclei, resulting in a dilution of the concentration of infectious particles in the room. <> Respiratory Protection • What is the difference between a CDC/NIOSH-certified respirator and a surgical or procedure mask? Respirators are designed to help reduce the wearer’s (i.e., HCW’s) exposure to airborne particles. The primary purpose of a surgical or procedure mask is to help prevent biologic particles from being expelled into the air by the wearer (i.e., patient). • How important is the fit of the respirator? This step is critical. The fit of a respirator is substantially important. If a respirator does not fit tightly on the face, airborne hazards can penetrate or enter underneath the facepiece seal and into the breathing zone. Before each use, the wearer of a respirator should perform a user-seal check on themselves to minimize contamina
