Face Masks


  • multiple types of face mask are used for personal protection


  • personal protection
  • protection of patient from health care nasopharyngeal secretions


Standard Surgical Facemask (some come with a visor attached)

N95 Face Mask (‘duckbill’)

N100 Face Mask


  • placed over the mouth and nose


Surgical Face Mask

  • designed to catch bacteria shed in liquid droplets and aerosol form from the wearer’s mouth and nose
  • can protect wearer from being splashed in the mouth from body fluids
  • also serves as a reminder not to touch mouth or nose
  • they do not prevent inhalation of bacteria or viruses


  • Used for respiratory droplet infection spread (eg SARS, influenza, Tb) for general presence in room (not procedures)
  • used for  reverse barrier nursing in severely immunocompromised patients
  • certified to filter 95% of particles of a particular test size
  • The N refers to the ability to resist oil (N stands for Non-oil resistant). R means resistant to oil and P means oil proof
  • filters out the droplets that carry viruses (the viruses themselves would be small enough to pass through the filter)
  • should not be put back on if removed
  • should be replaced every 6 hours (WHO recommendation)


  • more expensive
  • highest filtering of respiratory particles/diseases
  • CDC recommends masks better than N95 for procedures likely to produce droplets (e.g. airway suctioning, intubation) if airborne precautions are needed
