When respiratory protection is required or recommended for health care workers to help reduce their exposures to airborne particles, including bacteria and viruses that may cause disease, most often the requirement is for them to use an “N95, FFP2 or equivalent” filtering face piece respirator.
When used correctly, respirators can help reduce wearers’ exposures to airborne particulate hazards, including both bio aerosols and no biological aerosols. Respirators contain filter material and are designed to form a seal with the wearer’s face, so that air passes through the filter (instead of around the edges) before it is inhaled. A common choice is a disposable filtering face piece respirator (FFR).
